The present invention relates to a branch sleeve for connecting a distribution line that can prevent a safety accident by preventing corrosion and low voltage caused by electrolysis caused by the connection of a heterogeneous metal.

일반적으로 전력의 배전시 22.9kV의 특고압을 배전전압으로 하여 전기공급장소의 주상변압기까지 공급한 후, 배전용 주상변압기에서 220V, 380V의 저압으로 변환하여 일반 가정이나 산업체 등의 전기 수요자에게 공급하게 된다.In general, when the power is distributed, it supplies to the columnar transformer of the electricity supply site with the special high voltage of 22.9kV as the distribution voltage, and then converts it to the low voltage of 220V and 380V in the distribution columnar transformer and supplies it to the electric consumers such as general homes or industries. Done.

이러한 배전선로의 본선로에서 선로를 분리하거나 본선로에서 주상변압기로 전력을 제공하는 경우 본선과 분기선에 분기 슬리브를 장착하여 두 선을 접속하게 되는데, 본선과 분기선을 접속하고 있는 분기 슬리브에는 커버를 장착하여 빗물이나 조류에 의한 피해 등 외부로부터의 여러 가지 악영향들을 방지하는 한편 분기부를 절연시키고 있다. When the main line of the distribution line is separated from the main line or the electric power is supplied from the main line to the main transformer, the branch sleeve is connected to the main line and the branch line to connect the two lines, and the branch sleeve connecting the main line and the branch line has a cover. It prevents various adverse influences from the outside, such as damage caused by rainwater or algae, and insulates the branch.

종래의 가공배전선로가 설치된 전주의 설치형태는 도 1에 도시된 바와 같다.The installation form of the pole installed with the conventional overhead distribution line is as shown in FIG.

즉, 전주(1)에는 전력이 송전되는 본선(2)과 컷아웃스위치(3)와 주상변압기(4) 및 애자 등이 장착되어 있으며, 본선(2)을 통해 배전되는 전력은 컷아웃스위치(3)를 거쳐 주상변압기(4)로 제공되고, 주상변압기(4)는 특고압으로 배전되는 전력을 사용 가능한 정격 전압(220V, 380V)으로 낮추어 인하선(8)을 통해 전력선(5)으로 제공하여 가정이나 산업체 등의 전기 수용자에게 공급하게 된다.That is, the main pole 1 is equipped with a main line (2) and a cutout switch (3), a pole transformer (4), insulator, etc., the electric power is transmitted, the power distributed through the main line (2) is cutout switch ( 3) is provided to the columnar transformer (4), the columnar transformer (4) is provided to the power line (5) through the lower line (8) by lowering the power to be distributed to the extra high voltage to the available rated voltage (220V, 380V) In order to supply electricity to households and industrial consumers.

이러한 구성에서 본선(2)은 전주(1)에 설치된 양측 인류클램프 커버(6)에 고정 설치되고, 양측 인류클램프 커버(6) 사이의 장력이 걸리지 않는 본선(2) 부위에 분기선(7)이 분기 슬리브(10)로 접속되어 컷아웃스위치(3)로 전력이 공급되며, 분기 슬리브(11)의 외부에 커버(11)가 설치된다.In this configuration, the main line 2 is fixedly installed on both human clamping covers 6 provided on the pole 1, and branch lines 7 are formed at the main line 2 where the tension between the two human clamping covers 6 is not applied. It is connected to the branch sleeve 10 to supply power to the cutout switch 3, and a cover 11 is installed outside the branch sleeve 11.

여기서, 도 2에 도시된 바와 같이, 상기 분기 슬리브(10)는 빗물이 스며들지 못하게 하는 한편 절연시켜 감전사고를 방지하고자 분기 슬리브 커버(11)에 의해 감싸진 체 전선을 접속하도록 되어 있는 바, 상기 분기 슬리브 커버(11)는 분기 슬리브(10)가 안치될 수 있는 내부공간이 마련된 양단부에 원추형태로 인출구(12)가 형성되어 본선(2)이 끼워져 설치되며, 인출구(12)에서 하단부로 절개되어 양분할되고, 분할된 하단부의 양쪽에 체결턱과 체결편으로 이루어진 수개의 체결구(13)가 형성된다.Here, as shown in Figure 2, the branch sleeve 10 is to be connected to the sieve wire wrapped by the branch sleeve cover 11 to prevent rain from seeping into the insulation and to prevent electric shock, The branch sleeve cover 11 is formed with a conical outlet (12) formed at both ends provided with an inner space in which the branch sleeve (10) can be placed, the main line (2) is fitted, from the outlet (12) to the lower end A plurality of fasteners 13, each consisting of a fastening jaw and a fastening piece, are formed on both sides of the cut and divided into two parts.

이처럼 종래의 분기 슬리브(10)는 본선(2)의 피복을 제거하고 분기선(7)을 접속한 상태에서 분기 슬리브 커버(11)의 분할된 하단부를 벌려 분기 슬리브(11)를 내부에 안치하고, 양측 본선(2)을 인출구(12)에 끼워 인출시킨 다음 분기선(7)을 한쪽 인출구(12)로 인출한 상태에서 수개의 체결구(13)를 결합하고, 양측 인출 구(12) 부위를 테이핑 작업으로 밀폐시켜 빗물이 스며들지 못하게 하는 한편 절연시켜 감전사고를 방지하게 된다.As such, the conventional branch sleeve 10 opens the divided lower end of the branch sleeve cover 11 in a state in which the covering of the main line 2 is removed and the branch line 7 is connected, and the branch sleeve 11 is placed therein. The two main wires 2 are drawn out by inserting them into the outlet port 12, and then several fasteners 13 are engaged with the branch line 7 being drawn out to one outlet port 12, and the two outlet ports 12 are taped. It is sealed by work to prevent rainwater from seeping into it, and it is insulated to prevent electric shock.

그리고, 도 3 및 도 4에 도시된 바와 같이, 종래의 일반적인 분기 슬리브(10)는 상부측에 분기 슬리브의 본선 측 장착홈(12)이 형성되어 있고, 하부 측에는 분기선(7) 측 장착홈(14)이 형성되어 있다.3 and 4, in the conventional general branch sleeve 10, the main line side mounting groove 12 of the branch sleeve is formed on the upper side, and the branch line 7 side mounting groove ( 14) is formed.

이에 따라 상기 분기 슬리브(10)의 본선(2) 측 장착홈(12)에는 본선(2)이 압착된 상태로 장착되고, 분기선(7) 측 장착홈(14)에는 분기선(7)이 압착되어 분기 접속되는 것이다.Accordingly, the main line 2 is mounted to the main line 2 side mounting groove 12 of the branch sleeve 10 in a crimped state, and the branch line 7 is crimped to the branch line 7 side mounting groove 14. It is a branch connection.

그런데, 종래 알루미늄 전선과 동선을 연결하기 위하여 알루미늄 재질이며 일부에 절결부를 갖는 원호상의 장착부를 양측에 설치한 기존의 알루미늄선용 분기슬리브(10)를 사용하였다.However, in order to connect the aluminum wire and the copper wire in the related art, the conventional aluminum wire branch sleeve 10 provided with mounting portions on both sides of an arc material having a cutout portion in aluminum is used.

그러나, 일반적인 분기 슬리브(10)는 알루미늄과 구리가 이질 접속됨과 아울러 분기 슬리브(10)와 동선이 완전 밀착이 이루어지지 않아 이의 경계면에 수분, 습기 또는 이물질이 침투하게 되고, 이에 따라 이온화 전위가 낮은 알루미늄이 용해부식되어 접촉저항을 증가시켜 접속부의 온도상승으로 인한 전해 부식이 가속화되어 산화피막이 형성되고, 접촉불량을 야기하여 단선사고등을 일으키는 등의 문제점이 발생되었다.However, the general branch sleeve 10 has a heterogeneous connection between aluminum and copper, and the branch sleeve 10 is not completely in contact with the copper wire, so that moisture, moisture, or foreign matter penetrates the interface thereof, and thus the ionization potential is low. As aluminum is melted and corroded, the contact resistance is increased to accelerate the electrolytic corrosion due to the temperature rise of the connection part, thereby forming an oxide film, causing contact failure, and causing disconnection accidents.

이에 본 고안은 상기와 같은 종래 분기 슬리브의 문제점을 개선하기 위하여 안출된 것으로, 본 고안의 목적은 분기슬리브의 동선이 안착되는 장착부 내주면에 일측에 절결부를 갖는 원호상의 동관을 완전밀착 삽입고정하여 동선 연결시 원호상의 동관에 접속되도록 하거나 장착부 내주면에 주석 도금을 실시함으로써, 장시간 사용으로 발생되는 전식에 의한 부식의 발생을 최대한 방지하여 저전압을 방지하고 안전사고를 예방할 수 있는 배전 선로 접속용 분기 슬리브를 제공함에 있다.The present invention has been devised to improve the problems of the conventional branch sleeve as described above, the object of the present invention is to fully insert the arc-shaped copper tube having a cutout at one side on the inner peripheral surface of the mounting portion in which the copper wire of the branch sleeve is seated Branch copper sleeves for connection to distribution lines that can be connected to copper tubes on arcs or tin-plated on the inner circumference of the mounting part to prevent corrosion due to electrical corrosion caused by prolonged use to prevent low voltage and prevent safety accidents. In providing.

상기와 같은 목적을 달성하기 위한 본 고안은 배전 선로의 본선과 분기선을 상호 접속하기 위하여 일측이 개구 절결된 본선 측 제1접속홈과 분기선 측 제2접속홈을 갖춘 알루미늄 도체의 배전 선로 접속용 분기 슬리브에 있어서, 상기 분기선 측 제2접속홈은 밀폐공 구조를 갖고, 이 제2접속홈 내주면에 동(銅)재질의 동관이 삽입 장착되며, 상기 동관에 분기선을 인입시켜 압축하여 분지 접속시키는 것을 특징으로 하는 배전 선로 접속용 분기 슬리브를 제공함으로써 달성된다.The present invention for achieving the above object is a branch for connecting a distribution line of an aluminum conductor having a main connection side first connection groove and a branch line side second connection groove in which one side is opened to interconnect the main line and the branch line of the distribution line. In the sleeve, the branch line side second connecting groove has a closed hole structure, and a copper tube made of copper material is inserted into the inner peripheral surface of the second connecting groove, and a branch line is inserted into the copper pipe to compress and branch. It is achieved by providing a branch sleeve for connecting a distribution line.

여기서, 상기 제2접속홈의 내주면에는 주석 도금이나 은도금을 실시하는 것이 바람직하다.Here, it is preferable to perform tin plating or silver plating on the inner circumferential surface of the second connection groove.

본 고안에 따르면, 분기 슬리브의 제2접속홈에 동관을 삽입하고, 여기에 동선인 분기선을 결합시에 피복을 벗긴 상태로 분기 슬리브의 제2접속홈에 삽입하여 결합 후에 압축하여 제2접속홈 외면에 틈새가 전혀 없도록 함으로써, 접속부위의 부식을 방지하고, 접지면의 저항치를 줄여 접속부위의 온도 상승으로 인한 잦은 정전을 예방하여 안전사고를 방지하도록 하는 효과가 있다.According to the present invention, the copper tube is inserted into the second connecting groove of the branch sleeve, and the copper wire is inserted into the second connecting groove of the branch sleeve in a state where the copper wire is stripped at the time of joining, and then compressed after joining. The absence of any gaps on the outer surface prevents corrosion of the connection area and reduces the resistance of the ground plane to prevent frequent power failures caused by the temperature increase in the connection area, thereby preventing safety accidents.

이하 본 고안의 바람직한 실시예에 대해서 첨부도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 5 내지 도 7에 도시된 바와 같이, 본 고안은 배전선로의 본선(111)과 분기선(112)을 상호 접속하기 위하여 본선(111) 측 제1접속홈(101)과 분기선(112) 측 제2접속홈(102)을 갖춘 분기 슬리브(100)에 관한 것으로, 상기 분기 슬리브(100)는 알루미늄 재질로 제조된다.As shown in FIG. 5 to FIG. 7, the present invention provides the first connection groove 101 and the branch line 112 side of the main line 111 in order to interconnect the main line 111 and the branch line 112 of the distribution line. It relates to a branch sleeve 100 having a two-connected groove 102, the branch sleeve 100 is made of aluminum.

여기서, 본 고안에 따른 분기 슬리브(100)는, 상기 분기선(112) 측 제2접속홈(102)에 동(銅)재질의 동관(110)이 삽입 장착되고, 여기에 분기선(112)을 삽입하여 압축함으로써 분지 접속시킨 구조로 되어 있다.Here, the branch sleeve 100 according to the present invention, the copper tube 110 of the copper material is inserted into the second connecting groove 102 on the branch line 112 side, the branch line 112 is inserted therein. By compression to form a branched connection.

즉, 본 고안은 도 7에 도시된 바와 같이 본선 측 제1접속홈(3)은 일측이 개구된 고리형 절결부로 구성되어 있어 여기에 전력 본선(1)이 압착 장착되게 되고, 분기선(112) 측 제2접속홈(102)은 밀폐공 구조로 형성되어 여기에 분기선(112)이 삽입 압착되어 분기 접속상태를 유지하게 되는 바, 상기와 같이 제2접속홈(102)에는 동관(110)이 삽입되어 이 동관(110)을 통해 피복이 벗겨진 분기선(112)이 접속되도록 되어 있는 것이다.That is, the present invention, as shown in Fig. 7, the main connection side first connection groove 3 is composed of an annular cut-out portion of which one side is opened so that the power main line 1 is crimp-mounted and the branch line 112 The second side connection groove 102 is formed in a closed hole structure, and the branch line 112 is inserted and compressed therein to maintain the branch connection state. As described above, the second connection groove 102 has a copper tube 110. The branch line 112 which is inserted and peeled off through the copper pipe 110 is connected.

다시 말해, 종래 도 3 및 도 4에 도시된 바와 같은 분기 슬리브(10)의 경우, 분기선(7)이 장착되는 분기선(7) 측 장착홈(14)의 일측이 개구되어 있으나, 본 고안의 경우, 상기 동관(110)이 삽입 안착되는 제2접속홈(102)이 밀폐공 구조를 갖는 차이점을 가지고 있다.In other words, in the case of the branch sleeve 10 as shown in FIGS. 3 and 4, one side of the mounting groove 14 on the branch line 7 side on which the branch line 7 is mounted is opened, but in the present invention The second connection groove 102 into which the copper tube 110 is inserted and seated has a difference in a closed hole structure.

그리고, 상기 제2접속홈(102)이 형성된 분기 슬리브(100)의 몸체 하단 폭을 최대한 줄여서 도시되지 않은 압착기를 이용하여 압착할 때, 압착 작업을 용이하게 수행하도록 하고 있다.In addition, when the bottom width of the body of the branch sleeve 100 in which the second connection grooves 102 are formed is reduced as much as possible, the compression operation is easily performed by using a compactor (not shown).

특히, 상기 제2접속홈(102)의 내주면에는 전도율이 좋은 주석 도금이나 은 도금을 실시하는 것이 바람직하다.In particular, it is preferable to perform tin plating or silver plating with good conductivity on the inner circumferential surface of the second connection groove 102.

즉, 알루미늄 재질로 이루어진 분기 슬리브(100)에 형성된 제2접속홈(102) 내주면에 주석 도금이나 은 도금을 실시함으로써, 상기 제2접속홈(102)에 동관(110) 삽입 시 이질 금속의 접촉에 의한 전해부식 정도를 완화시킬 수 있는 효과가 있는 것이다.That is, tin plating or silver plating is performed on the inner circumferential surface of the second connecting groove 102 formed in the branch sleeve 100 made of aluminum, so that the contact of the foreign metal when the copper tube 110 is inserted into the second connecting groove 102. The effect is to mitigate the degree of electrolytic corrosion.

여기서, 본 고안은 상기 알루미늄 재질의 본선(111) 측 제1접속홈(101)에는 알루미늄 전력 본선(111)이 장착되고, 동(銅)재질의 동관(110)이 내장된 분기선(112) 측 제2접속홈(102)에는 동(銅)선인 분기선(112)이 장착되어 분기 접속되어 있다. Here, the present invention is the main line 111 side of the aluminum material, the first connection groove 101, the aluminum power main line 111 is mounted, the branch line 112 side in which the copper tube 110 of the copper material is embedded.

It can be prevented.

상기와 같이 구성된 본 고안은 전신주 등에 사용되는 중선선인 전력 본선(111, 즉,알루미늄 전선)을 제1접속홈(101)의 내주면에 피복을 벗긴 상태로 일정 길이만큼 안착시킨 다음, 도시되지 않은 압착기에 의해 제1접속홈(101)을 압착하여 개구된 절결부를 밀폐하여 본선(111,알루미늄 전선)을 접속한다.According to the present invention configured as described above, the electric main line 111 (that is, an aluminum wire), which is a heavy wire used for telegraph poles, is seated by a predetermined length in a state in which the inner circumferential surface of the first connection groove 101 is peeled off, The first connection groove 101 is pressed to close the open cutout portion to connect the main wire 111 (aluminum wire).

By pressing using a non-compressor to compress, the connection is made in the state that the gap between the inner circumferential surface of the copper tube 110 and the second connection groove 102 and the contact surface gap between the branch line 112 and the copper tube 110 are removed as much as possible. To complete.

이때, 상기 제2접속홈(102)의 내주면에 동관(110)이 알루미늄 재질인 분기 슬리브(100)와 안전 밀착되어 구비되고, 상기 분기선(112)은 동관(110)의 내주면에 안착되어 접속되어 있으므로 동관(110)과 분기선(112)은 동일한 재질끼리 접촉되어 있어 전해부식을 방지하여 저전압의 발생을 방지할 수가 있다.At this time, the copper tube 110 is provided on the inner circumferential surface of the second connection groove 102 in close contact with the branch sleeve 100 made of aluminum, and the branch line 112 is seated and connected to the inner circumferential surface of the copper tube 110. Therefore, the copper tube 110 and the branch line 112 are in contact with the same material, it is possible to prevent the electrolytic corrosion to prevent the occurrence of low voltage.

또한 상기 동관(110)과 제2접속홈(102)의 내주면은 이질 금속으로 접촉되어 있으나, 상기 동관(110)이 제2접속홈(102)에 완전 밀착된 상태로 삽입 압착됨에 따라 동관(110)과 제2접속홈(102)의 내주면과의 틈새가 최대한 제거되어 틈새에 수분, 습기 또는 이물질이 침투되는 것을 최대한 방지하여 전해부식을 방지할 수 있는 것이다.In addition, the inner circumferential surface of the copper tube 110 and the second connection groove 102 is in contact with the heterogeneous metal, but the copper tube 110 is inserted and pressed in a state that the copper tube 110 is completely in contact with the second connection groove 102, the copper tube 110 ) And the gap between the inner circumferential surface of the second connection groove 102 is removed as much as possible to prevent the penetration of moisture, moisture or foreign matter to the gap to prevent electrolytic corrosion.

특히, 상기 제2접속홈(102)의 내주면에 주석 도금이나 은 도금을 할 경우에는 동관(110)과 알루미늄 재질의 분기 슬리브(100)와의 접속 관계가 아닌 동 관(110)과 주석과 접속 관계를 가짐으로 상대적으로 전해 부식을 방지하는 효과가 더 배가될 수 있는 것이다.In particular, when tin plating or silver plating is performed on the inner circumferential surface of the second connection groove 102, the connection relationship between the copper tube 110 and the tin is not connected to the copper tube 110 and the branch sleeve 100 made of aluminum. By having the relative effect of preventing electrolytic corrosion can be further doubled.
