Abstract

An electromagnetically operated switching device is provided with an electromagnetic-operation-mechanism driving shaft and a main-circuit-contact moving shaft connecting to a contact pressure spring section or an insulated rod section and opening and closing a main circuit contact section.  A gap in the radial direction of both the shafts is provided at the joint between the shafts, and a gap is also provided in the axial direction of both the shafts so that the shafts can be displaced relative to each other in the radial direction.  The number of winding of the contact pressure spring section using a coiled spring is set to a number other than integers by shifting the start portion and the end portion of winding of the contact pressure spring section from each other in the circumferential direction.  An angle change link for changing the angle of connection between the electromagnetic-operation-mechanism driving shaft and the main-circuit-contact moving shaft, which connects to the contact pressure spring section or the insulated rod section and opens and closes the main circuit contact section, is used to interconnect both the shafts such that the shafts are tilted in the range from 45˚ to 180˚.  The configuration stabilizes pole opening/closing operation of the electromagnetically operated switching device so that the operation is independent of the accuracy of parts and assembling, and the electromagnetically operated switching device occupies a reduced installation space.

　この発明は、電力の送配電および受電設備等に用いられる、電磁操作機構を用いた開閉装置に関するものである。 The present invention relates to a switchgear using an electromagnetic operation mechanism, which is used in power transmission / distribution and power receiving facilities.
　従来の電磁操作方式開閉装置は、主回路電流の開閉を行う主回路接点部，主回路部と操作機構とを電気的に絶縁する絶縁ロッド部、および主回路接点に接圧を与える接圧ばね部と、電磁操作機構部とが一軸上に配置、締結され、操作回路によって制御される電磁操作機構の開極用コイル、および閉極用コイルに電流を流すことにより可動子を所定の方向に駆動させ、主回路接点の開極、あるいは閉極動作を行っている（例えば、特許文献１参照）。 A conventional electromagnetic operation type switchgear includes a main circuit contact part that opens and closes a main circuit current, an insulating rod part that electrically insulates the main circuit part and the operation mechanism, and a contact pressure spring that applies contact pressure to the main circuit contact And the electromagnetic operation mechanism unit are arranged and fastened on one axis, and a current is passed through the opening coil and the closing coil of the electromagnetic operation mechanism controlled by the operation circuit to move the mover in a predetermined direction.

特願２００４－５６０５６７公報（図１）Japanese Patent Application No. 2004-560567 (FIG. 1)
　このように従来の電磁操作方式開閉装置においては、主回路接点部，絶縁ロッド部，接圧ばね部、および電磁操作機構部が一軸上に配置されているため、上記主回路接点部，絶縁ロッド部，接圧ばね部、および電磁操作機構部での中心軸の軸心ずれ、あるいは中心軸の倒れにより、電磁操作機構に偏荷重が印加され、電磁操作方式開閉装置の動作が安定しない問題があった。また、主回路接点部，絶縁ロッド部，接圧ばね部、および電磁操作機構部が一軸上に配置したため、電磁操作方式開閉装置の全長が長くなり、電磁操作方式開閉装置の設置スペースが大きくなる問題があった。 As described above, in the conventional electromagnetic operation type switching device, the main circuit contact portion, the insulating rod portion, the contact pressure spring portion, and the electromagnetic operation mechanism portion are arranged on one axis. There is a problem that an eccentric load is applied to the electromagnetic operating mechanism due to a shift of the center axis of the central axis in the contact portion, the contact pressure spring portion, and the electromagnetic operating mechanism unit, or a tilt of the central axis, and the operation of the electromagnetic operating type switchgear is not stable. there were. In addition, the main circuit contact part, the insulating rod part, the contact pressure spring part, and the electromagnetic operation mechanism part are arranged on one axis, so the total length of the electromagnetic operation type switchgear becomes longer and the installation space for the electromagnetic operation type switchgear becomes larger. There was a problem.
　この発明は、上記のような問題を解消するためになされたものであり、電磁操作機構部への偏荷重の発生を簡単な機構で確実に抑制し、また電磁操作方式開閉装置の全長を短縮し電磁操作方式開閉装置の設置スペースを縮小可能な電磁操作方式開閉装置を提供することを目的とする。 The present invention has been made to solve the above-described problems, and it is possible to reliably suppress the occurrence of an uneven load on the electromagnetic operation mechanism with a simple mechanism, and to shorten the overall length of the electromagnetic operation type switching device. It is an object of the present invention to provide an electromagnetic operation type switchgear that can reduce the installation space of the electromagnetic operation type switchgear.
　この発明は、主回路電流の開閉を行う主回路接点部，主回路部と操作機構とを電気的に絶縁する絶縁ロッド部，主回路接点に接圧を与える接圧ばね部、および主回路接点を開閉動作させさらに開状態および閉状態を保持させる電磁操作機構部を有する電磁操作方式開閉装置において、電磁操作機構部駆動軸と、接圧ばね部あるいは絶縁ロッド部につながり主回路接点部を開閉させる主回路接点可動軸との接合部にて、両軸の径方向に空隙を設け、両軸が互いに径方向に変移出来るよう軸方向にも空隙を設けたものである。 The present invention relates to a main circuit contact portion that opens and closes a main circuit current, an insulating rod portion that electrically insulates the main circuit portion and an operation mechanism, a contact pressure spring portion that applies a contact pressure to the main circuit contact, and a main circuit contact In an electromagnetic operation type switchgear that has an electromagnetic operation mechanism that opens and closes and opens and closes the main circuit contact part connected to the electromagnetic operation mechanism drive shaft and the contact pressure spring or insulation rod A gap is provided in the radial direction of both shafts at the joint with the main circuit contact movable shaft to be moved, and a gap is also provided in the axial direction so that both shafts can be shifted in the radial direction.
　また、主回路電流の開閉を行う主回路接点部，主回路部と操作機構とを電気的に絶縁する絶縁ロッド部，主回路接点に接圧を与える接圧ばね部、および主回路接点を開閉動作させさらに開状態および閉状態を保持させる電磁操作機構部を有する電磁操作方式開閉装置において、コイルばねを用いた接圧ばねのコイル巻き始め端部とコイル巻き終わり端部とを周方向にずらし整数以外の巻き数としたものである。 In addition, the main circuit contact part that opens and closes the main circuit current, the insulating rod part that electrically insulates the main circuit part and the operating mechanism, the contact pressure spring that applies contact pressure to the main circuit contact, and the main circuit contact In an electromagnetic operation type switchgear having an electromagnetic operation mechanism for operating and maintaining an open state and a closed state, a coil winding start end and a coil winding end of a contact pressure spring using a coil spring are shifted in the circumferential direction. The number of turns is other than an integer.
　また、主回路電流の開閉を行う主回路接点部，主回路部と操作機構とを電気的に絶縁する絶縁ロッド部，主回路接点に接圧を与える接圧ばね部、および主回路接点を開閉動作させさらに開状態および閉状態を保持させる電磁操作機構部を有する電磁操作方式開閉装置において、電磁操作機構部駆動軸と、接圧ばね部あるいは絶縁ロッド部につながり主回路接点部を開閉させる主回路接点可動軸との接続角度を変換する角度変換リンクを用いて、電磁操作機構部駆動軸と主回路接点可動軸とを４５°から１８０°傾けて接続したものである。 In addition, the main circuit contact part that opens and closes the main circuit current, the insulating rod part that electrically insulates the main circuit part and the operating mechanism, the contact pressure spring that applies contact pressure to the main circuit contact, and the main circuit contact In an electromagnetic operation type switchgear having an electromagnetic operation mechanism part that operates and further maintains an open state and a closed state, the main circuit contact part connected to the electromagnetic operation mechanism part drive shaft and the contact pressure spring part or the insulating rod part is opened and closed. The electromagnetic operating mechanism drive shaft and the main circuit contact movable shaft are connected at an angle of 45 ° to 180 ° using an angle conversion link that converts the connection angle with the circuit contact movable shaft.
　この発明の電磁操作方式開閉装置によれば、電磁操作機構部駆動軸と、接圧ばね部あるいは絶縁ロッド部につながり主回路接点部を開閉させる主回路接点可動軸との接合部にて、両軸の径方向に空隙を設け、両軸が互いに径方向に変移出来るよう軸方向にも空隙を設けたものなので、電磁操作機構部駆動軸と主回路接点可動軸との軸ずれ、軸の傾きに起因する電磁操作機構部駆動軸への偏荷重を抑制し、電磁操作方式開閉装置の動作の安定化が可能となる。 According to the electromagnetic operation type opening / closing device of the present invention, both the electromagnetic operation mechanism drive shaft and the main circuit contact movable shaft connected to the contact pressure spring portion or the insulating rod portion to open and close the main circuit contact movable shaft A gap is provided in the axial direction of the shaft, and a gap is also provided in the axial direction so that both shafts can shift in the radial direction. Accordingly, it is possible to suppress the unbalanced load on the drive shaft of the electromagnetic operation mechanism unit due to the above, and to stabilize the operation of the electromagnetic operation type switchgear.
　また、コイルばねを用いた接圧ばねのコイル巻き始め端部とコイル巻き終わり端部とを周方向にずらし整数以外の巻き数としたものであるので、コイルばねの特異点であるコイル巻き始め端部とコイル巻き終わり端部とを相対的にずらし、コイル巻き始め端部とコイル巻き終わり端部に起因するコイルばねの倒れを抑制することができ、電磁操作機構部駆動軸に印加される偏荷重の発生を抑えることが可能となる。 In addition, since the coil winding start end portion and the coil winding end end portion of the contact pressure spring using the coil spring are shifted in the circumferential direction so as to have a winding number other than an integer, the coil winding start which is a singular point of the coil spring is used. The end of the coil winding and the end of the coil winding end are relatively shifted, and the coil spring collapse caused by the coil winding start end and the coil winding end end can be suppressed and applied to the electromagnetic operation mechanism drive shaft. It is possible to suppress the occurrence of an uneven load.
　また、電磁操作機構部駆動軸と、接圧ばね部あるいは絶縁ロッド部につながり主回路接点部を開閉させる主回路接点可動軸との接続角度を変換する角度変換リンクを用いて、電磁操作機構部駆動軸と主回路接点可動軸とを４５°から１８０°傾けて接続したものであるので、主回路接点部，絶縁ロッド部，接圧ばね部、および電磁操作機構部を一軸上に配置する必要がなくなり、電磁操作方式開閉装置の全長を短縮することが可能となり、電磁操作方式開閉装置の設置スペースを縮小することが可能となる。 In addition, the electromagnetic operation mechanism unit is configured using an angle conversion link that converts the connection angle between the electromagnetic operation mechanism unit drive shaft and the main circuit contact movable shaft that opens and closes the main circuit contact unit connected to the contact pressure spring unit or the insulating rod unit. Since the drive shaft and the main circuit contact movable shaft are connected at an angle of 45 ° to 180 °, the main circuit contact portion, the insulating rod portion, the contact pressure spring portion, and the electromagnetic operation mechanism portion need to be arranged on one axis. Therefore, it is possible to reduce the total length of the electromagnetic operation type switchgear and to reduce the installation space of the electromagnetic operation type switchgear.

　以下、本発明の実施例１について説明する。図１は主回路接点閉状態における電磁操作方式開閉器の１相に対する全体構成図であり、各相に設けられるものである。開閉可能に配設された主回路接点１は、可動側主回路接点１ａおよび固定側主回路接点１ｂにて構成され、主回路接点１は例えば真空中にて開閉を行う。可動側主回路接点１ａは可とう導体２を介して可動側端子３に接続されるとともに、主回路を電気的に絶縁する絶縁ロッド４，主回路接点可動軸５に接続され、電磁操作機構側接圧ばね受け９ａ，主回路接点側接圧ばね受け９ｂ，ばね受け接続金具９ｃに保持された接圧ばね６を介して電磁操作機構駆動軸７を駆動する電磁操作機構８に接続されている。また固定側主回路接点１ｂは固定側端子２１に接続されている。 Hereinafter, Example 1 of the present invention will be described. FIG. 1 is an overall configuration diagram for one phase of an electromagnetically operated switch in a main circuit contact closed state, and is provided in each phase. The main circuit contact 1 arranged to be openable / closable is composed of a movable side main circuit contact 1a and a fixed side main circuit contact 1b. The main circuit contact 1 opens and closes in a vacuum, for example. The movable side main circuit contact 1a is connected to the movable side terminal 3 through the flexible conductor 2, and is connected to the insulating rod 4 and the main circuit contact movable shaft 5 to electrically insulate the main circuit. The contact pressure spring receiver 9a, the main circuit contact side contact pressure spring receiver 9b, and the contact pressure spring 6 held by the spring receiver connection fitting 9c are connected to the electromagnetic operation mechanism 8 that drives the electromagnetic operation mechanism drive shaft 7. . The fixed-side main circuit contact 1 b is connected to the fixed-side terminal 21.
　図２は電磁操作機構駆動軸７および接圧ばね６付近を示す拡大図であり、図３は主回路接点開状態における電磁操作機構駆動軸７および接圧ばね６付近を示す拡大図である。電磁操作機構駆動軸７には、ナット１０ａ，１０ｂがばね受け接続金具９ｃの両側に固定され、０．１ｍｍ程度の空隙１１ａあるいは１１ｂが設けられている。ナット１０ａあるいは１０ｂとばね受け接続金具９ｃとは接触状態であり、主回路接点閉状態ではナット１０ａとばね受け接続金具９ｃとが接触部１２ａ部にて接触、主回路接点開状態ではナット１０ｂとばね受け接続金具９ｃとが接触部１２ｂ部にて接触している。 2 is an enlarged view showing the vicinity of the electromagnetic operating mechanism drive shaft 7 and the contact pressure spring 6, and FIG. 3 is an enlarged view showing the vicinity of the electromagnetic operating mechanism drive shaft 7 and the contact pressure spring 6 in the main circuit contact open state. The electromagnetic operating mechanism drive shaft 7 has nuts 10a and 10b fixed to both sides of the spring support fitting 9c, and is provided with a gap 11a or 11b of about 0.1 mm. The nut 10a or 10b and the spring receiving connection fitting 9c are in contact with each other. When the main circuit contact is closed, the nut 10a and the spring receiving connection fitting 9c are in contact with each other at the contact portion 12a. The spring receiving connection fitting 9c is in contact with the contact portion 12b.
　次に実施例１の動作について説明する。図１，図２では主回路接点閉状態にあり、電磁操作機構８は電磁操作機構駆動軸７、およびナット１０ａとの接触部１２ａを介して接圧ばね６を押し込み主回路接点１に接圧を与えている。主回路接点閉状態から開状態への駆動は、まず可動側主回路接点１ａが固定側主回路接点１ｂより離れる方向に、電磁操作機構駆動軸７が動作開始する。電磁操作機構駆動軸７の開動作に伴い接圧ばね６の押し込みが開放され、押し込みが完全に無くなると、主回路接点可動軸５を介して可動側主回路接点１ａが動作を開始する。可動側主回路接点１ａが開状態まで移動すると、例えば、主回路接点１が真空中にて開閉を行う場合、可動側主回路接点１ａには真空圧による自閉力が働くため、ばね受け接続金具９ｃとナット１０ｂが接触部１２ｂにて接触し、０．１ｍｍ程度の空隙１１ｂができる。 Next, the operation of the first embodiment will be described. 1 and 2, the main circuit contact is in a closed state, and the electromagnetic operation mechanism 8 pushes the contact pressure spring 6 through the contact portion 12a with the electromagnetic operation mechanism drive shaft 7 and the nut 10a to contact the main circuit contact 1. Is given. In driving from the main circuit contact closed state to the open state, first, the electromagnetic operating mechanism drive shaft 7 starts to move in a direction in which the movable side main circuit contact 1a is separated from the fixed side main circuit contact 1b. With the opening operation of the electromagnetic operating mechanism drive shaft 7, the pressing of the contact pressure spring 6 is released, and when the pressing completely disappears, the movable side main circuit contact 1 a starts to operate via the main circuit contact movable shaft 5. When the movable main circuit contact 1a moves to the open state, for example, when the main circuit contact 1 opens and closes in a vacuum, a self-closing force due to vacuum pressure acts on the movable main circuit contact 1a. The metal fitting 9c and the nut 10b come into contact with each other at the contact portion 12b, and a gap 11b of about 0.1 mm is formed.
　このように、実施例１では、ナット１０ａあるいは１０ｂとばね受け接続金具９ｃとは接触状態であり、主回路接点閉状態ではナット１０ａとばね受け接続金具９ｃとが接触部１２ａ部にて接触、主回路接点開状態ではナット１０ｂとばね受け接続金具９ｃとが接触部１２ｂ部にて接触しているため、電磁操作機構駆動軸７と主回路接点可動軸５との軸ずれ、軸の傾きに起因する電磁操作機構部駆動軸への偏荷重を抑制し、電磁操作方式開閉装置の動作の安定化が可能となる。 Thus, in Example 1, the nut 10a or 10b and the spring support fitting 9c are in contact with each other, and when the main circuit contact is closed, the nut 10a and the spring support connection fitting 9c are in contact with each other at the contact portion 12a. When the main circuit contact is in the open state, the nut 10b and the spring receiving connection fitting 9c are in contact with each other at the contact portion 12b, so that the axis of the electromagnetic operation mechanism drive shaft 7 and the main circuit contact movable shaft 5 are not aligned. It is possible to suppress the unbalanced load on the drive shaft of the electromagnetic operation mechanism section resulting from the stabilization of the operation of the electromagnetic operation type switchgear.
　なお、図４に示した通り、溝付電磁操作機構駆動軸７ａ，溝付ばね受け接続金具９ｄ，接続ピン２５を用いての接合においても上記と同様な効果が得られる。 Note that, as shown in FIG. 4, the same effect as described above can be obtained also in the joining using the grooved electromagnetic operation mechanism drive shaft 7a, the grooved spring receiving connection fitting 9d, and the connection pin 25.
　以下、本発明の実施例２について説明する。図５はコイルばねを用いた接圧ばね６の構造図であり、コイル巻き始め端部６ａとコイル巻き終わり端部６ｂとを接圧ばね６の周方向に１８０°の角度にずらしたものである。 Hereinafter, Example 2 of the present invention will be described. FIG. 5 is a structural diagram of the contact pressure spring 6 using a coil spring, in which the coil winding start end portion 6 a and the coil winding end end portion 6 b are shifted by an angle of 180 ° in the circumferential direction of the contact pressure spring 6. is there.
　このように、実施例２では、接圧ばね６のコイル巻き始め端部６ａとコイル巻き終わり端部６ｂとを接圧ばね６の周方向に１８０°の角度にてずらしたものであるため、コイルばねの特異点であるコイル巻き始め端部６ａとコイル巻き終わり端部６ｂとをコイルばね中心軸に対し対称位置にずらし、コイル巻き始め端部６ａとコイル巻き終わり端部６ｂに起因するコイルばねの倒れを抑制することができ、電磁操作機構部駆動軸に印加される偏荷重の発生を抑えることが可能となる。 As described above, in Example 2, the coil winding start end portion 6a and the coil winding end end portion 6b of the contact pressure spring 6 are shifted in the circumferential direction of the contact pressure spring 6 at an angle of 180 °. The coil winding start end 6a and the coil winding end 6b, which are singular points of the coil spring, are shifted to a symmetrical position with respect to the coil spring central axis, and the coil resulting from the coil winding start 6a and the coil winding end 6b The fall of the spring can be suppressed, and the occurrence of an unbalanced load applied to the electromagnetic operating mechanism drive shaft can be suppressed.
　以下、本発明の実施例３について説明する。図６は電磁操作機構駆動軸７と主回路接点可動軸５との接続に角度変換リンク１３を用いた接続状態を示す構造図であり、電磁操作機構駆動軸７と、接圧ばね６あるいは絶縁ロッド４（図示せず）につながり主回路接点１（図示せず）を開閉させる主回路接点可動軸５との接続角度を変換する角度変換リンク１３を用いて、電磁操作機構駆動軸７と主回路接点可動軸５とを９０°傾けて接続している。また、電磁操作方式開閉装置の開状態検出および閉状態検出に用いる回転式補助接点１４を、前記角度変換リンク１３に直接取り付けている。 Hereinafter, Example 3 of the present invention will be described. FIG. 6 is a structural diagram showing a connection state in which the angle conversion link 13 is used for connection between the electromagnetic operating mechanism drive shaft 7 and the main circuit contact movable shaft 5, and the electromagnetic operating mechanism drive shaft 7 and the contact pressure spring 6 or insulation. An electromagnetic operation mechanism drive shaft 7 and a main shaft are connected to each other by using an angle conversion link 13 that converts a connection angle with a main circuit contact movable shaft 5 that is connected to a rod 4 (not shown) and opens and closes a main circuit contact 1 (not shown). The circuit contact movable shaft 5 is connected at an angle of 90 °. Further, a rotary auxiliary contact 14 used for detecting an open state and a closed state of the electromagnetic operation type switchgear is directly attached to the angle conversion link 13.
　このように、実施例３では、電磁操作機構駆動軸７と、接圧ばね６あるいは絶縁ロッド４（図示せず）につながり主回路接点１（図示せず）を開閉させる主回路接点可動軸５との接続角度を変換する角度変換リンク１３を用いて、電磁操作機構部駆動軸と主回路接点可動軸とを９０°傾けて接続したものであるため、主回路接点１（図示せず），絶縁ロッド４（図示せず），接圧ばね６，および電磁操作機構８を一軸上に配置する必要がなくなり、電磁操作方式開閉装置の全長を短縮することが可能となり、電磁操作方式開閉装置の設置スペースを縮小することが可能となる。また回転式補助接点１４を角度変換リンク１３に直接取り付けているため、回転式補助接点１４を駆動させるリンクや引きばね等の部品が不要となり、部品点数の少ない回転式補助接点の設置が可能となる。 Thus, in Example 3, the main circuit contact movable shaft 5 connected to the electromagnetic operation mechanism drive shaft 7 and the contact pressure spring 6 or the insulating rod 4 (not shown) to open and close the main circuit contact 1 (not shown). Since the electromagnetic operation mechanism unit drive shaft and the main circuit contact movable shaft are connected at an angle of 90 ° using the angle conversion link 13 that converts the connection angle with the main circuit contact 1 (not shown), It is not necessary to arrange the insulating rod 4 (not shown), the contact pressure spring 6, and the electromagnetic operating mechanism 8 on one axis, and the overall length of the electromagnetic operating switchgear can be shortened. The installation space can be reduced. Further, since the rotary auxiliary contact 14 is directly attached to the angle conversion link 13, parts such as a link and a pulling spring for driving the rotary auxiliary contact 14 become unnecessary, and it is possible to install the rotary auxiliary contact with a small number of parts. Become.
　以下、本発明の実施例４について説明する。図７は電磁操作機構８と角度変換リンク１３を主回路接点可動軸５に対して対称配置した状態を示す構造図である。 Hereinafter, Example 4 of the present invention will be described. FIG. 7 is a structural diagram showing a state in which the electromagnetic operation mechanism 8 and the angle conversion link 13 are arranged symmetrically with respect to the main circuit contact movable shaft 5.
　このように、実施例４では、実施例３と同様な効果が得られ、さらに電磁操作方式開閉装置の開極距離の増加や接圧ばね荷重の増大等の電磁操作方式開閉装置の定格が異なるものへの対応が必要になった場合でも、電磁操作機構の個数を容易に増加させることが可能であり、様々な定格への変更が容易である。 As described above, in Example 4, the same effects as in Example 3 are obtained, and the ratings of the electromagnetically operated switchgear such as an increase in the opening distance of the electromagnetically operated switchgear and an increase in contact pressure spring load are different. Even when it becomes necessary to deal with things, it is possible to easily increase the number of electromagnetic operation mechanisms, and it is easy to change to various ratings.
　以下、本発明の実施例５について説明する。図８は主回路接点閉状態におけるワッシャー状接点消耗量インジケータ１５を示す構造図であり、図９は主回路接点閉状態にて接点消耗状態におけるワッシャー状接点消耗量インジケータを示す構造図である。ワッシャー状接点消耗量インジケータ１５は主回路接点可動軸５に設けられ、電磁操作方式開閉装置の閉状態にて電磁操作機構側接圧ばね受け９ａとワッシャー状接点消耗量インジケータ１５との主回路接点可動軸方向距離、つまり接圧ばねの圧縮量を測定することにより、主回路接点の接点消耗量が監視可能となる。 Hereinafter, Example 5 of the present invention will be described. FIG. 8 is a structural diagram showing the washer-like contact consumption amount indicator 15 in the main circuit contact closed state, and FIG. 9 is a structural diagram showing the washer-like contact consumption amount indicator in the contact consumption state in the main circuit contact closed state. The washer-like contact consumption amount indicator 15 is provided on the main circuit contact movable shaft 5, and the main circuit contact between the electromagnetic operation mechanism side contact pressure spring receiver 9 a and the washer-like contact consumption amount indicator 15 in the closed state of the electromagnetic operation type switching device. By measuring the distance in the movable axis direction, that is, the compression amount of the contact pressure spring, the contact consumption amount of the main circuit contact can be monitored.
　このように、実施例５では、電磁操作方式開閉装置の点検等にて主回路接点の接点消耗量を測定する場合、特別な測定器や治具等の必要性が無くなり、接点消耗量を測定作業の省力化が可能となる。 As described above, in Example 5, when the contact consumption amount of the main circuit contact is measured by inspection of the electromagnetic operation type switchgear, the need for a special measuring instrument or jig is eliminated, and the contact consumption amount is measured. Labor saving work is possible.
　なお、図１０はワッシャー状接点消耗量インジケータ１５の使用例であり、ワッシャー状接点消耗量インジケータ１５を、「要取替え」表示領域１５ａ，「注意」表示領域１５ｂ，「正常」表示領域１５ｃの３領域に塗分け、図８，図９図示の電磁操作機構側接圧ばね受け９ａ部からのワッシャー状接点消耗量インジケータ１５の突出部の上記領域を監視することにより、容易に接点消耗量を判定することが可能となる。 FIG. 10 shows an example of use of the washer-like contact consumption amount indicator 15. The washer-like contact consumption amount indicator 15 is divided into three parts, ie, “required replacement” display area 15a, “caution” display area 15b, and “normal” display area 15c. Easily determine the amount of contact wear by monitoring the above area of the washer-like contact wear amount indicator 15 protruding from the electromagnetic operating mechanism side contact pressure spring receiver 9a shown in FIGS. It becomes possible to do.
