Abstract
The invention relates to a high-voltage conveying switching device, in particular to a high-reliability outdoor pile high-voltage alternating current single-phase disconnecting switch. The high-reliability outdoor pile high-voltage alternating current single-phase disconnecting switch comprises a left composite insulator, a right composite insulator and a movable blade, and is characterized in that a support is fixedly installed at the lower end of the right composite insulator, a wire-out copper bar is arranged on the support, the movable blade is of an integral rod piece structure, and the right end of the movable blade is connected with the support through a rotating part and is connected with the wire-out copper bar in a soft-connection mode at the same time. A wire-in copper bar and a static contact arm connected with the wire-in copper bar are arranged at the lower end of the left composite insulator, a plum blossom contactor is fixedly arranged at the lower end of the static contact arm, and a movable contactor is arranged at the left end of the movable blade to be connected with the plum blossom contactor in an opening and closing mode. The high-voltage conveying switching device overcomes the defects that an ordinary disconnecting switch is corroded and loosened easily, switching-on positioning is not accurate, and the service life is short, and is mainly used for isolating overhead lines with the 12-kilovolt nominal voltage or the voltage below the nominal voltage.
Description
Technical field
The present invention relates to high-tension electricity and carry device for switching, high-voltage alternating single-phase isolating switch on especially a kind of high reliability outdoor column.
Background technology
At present for isolating switch on the outdoor column of voltage 12KV and following high-tension line (referring to Fig. 1,2) mainly by left and right composite insulator 1 and 8, line copper bar 2 and 7 and cutting blade 4 form, cutting blade 4 of the prior art is to be fastened by bolt clip by two blades, the one end is rotatably connected with the fixed contact 6 on right composite insulator 8 by axle 5, and adopt simultaneously spring 9 to strengthen the conduction connection with this conducting outlet copper bar 7(), the other end adopts 3 foldings of hook formula moving contact to be connected with right insulator, realizes separating brake, the closing operation of isolating switch.In the long-term work process, cutting blade and dynamic and static contact, friction, very easily cause surface abrasion due to isolating switch, thereby cause blade heating, distortion, finally cause the location of closing a floodgate inaccurate, destroyed the electric property of isolating switch, greatly shortened the useful life of isolating switch.
Summary of the invention
Purpose of the present invention will solve high-voltage alternating single-phase isolating switch on existing outdoor column exactly, conductive contact surfaces is easy to wear, and the blade distortion of easily generating heat causing the location of closing a floodgate inaccurate, the problems such as useful life is short, provide high-voltage alternating single-phase isolating switch on a kind of high reliability outdoor column.
Concrete scheme of the present invention is: improve for high-voltage alternating single-phase isolating switch on common outdoor column, it includes left and right composite insulator and cutting blade, it is characterized in that: in right composite insulator lower end, support is housed fixedly, outlet copper bar is housed on support, described cutting blade is the integral type member structure, its right-hand member is connected with support by rotating parts, and the right-hand member of cutting blade adopts simultaneously to be flexible coupling and is connected with outlet copper bar; Inlet wire copper bar and the stationary contact arm be connected with the inlet wire copper bar are housed in left composite insulator lower end, in stationary contact arm lower end, Mume flower contact are housed fixedly, at the left end of described cutting blade, moving contact is housed and is connected with the Mume flower contact opening and closing.
Being flexible coupling between cutting blade described in the present invention and outlet copper bar is flexible coupling for red copper.
Rotating parts between cutting blade described in the present invention and support is to adopt the aluminium alloy hinge.
An end of the present invention has been introduced the red copper conduction that is flexible coupling, and the other end adopts the Mume flower contact opening and closing to connect conduction, has avoided the possibility of blade because of wearing and tearing heating distortion fully, the combined floodgate accurate positioning, and never distortion, greatly extend useful life.The present invention is simple in structure, compactness, handling safety, convenience, stable and reliable operation, combined floodgate accurate positioning.
