Abstract
The invention relates to an embedded pole type vacuum load switch which comprises a pole body and a spring actuating mechanism. The pole body comprises a vacuum arc-extinguishing chamber, an insulating shell, an upper outlet, a lower outlet, an insulated pull rod and a crank arm. The vacuum arc-extinguishing chamber is sealed in the epoxy resin shell, so the insulating property is good, and thereby the service life and safety of the vacuum load switch are increased. A conductive rod of the moving end of the vacuum arc-extinguishing chamber is connected with the lower outlet through a flexible copper strip connector, and the upper outlet is embedded into the insulating shell, so the electrical insulation property is high.
Description
Technical field
The present invention relates to a kind of accessory of high voltage electric power equip ment, particularly a kind of embedded pole type vacuum load switch.
Background technology
Vacuum load switch has been widely used in the switch cubicle, and the vacuum load switch major loop mainly is made up of conduction major loop and operating mechanism.The conduction major loop develops into the pole type structure from unenclosed construction at present.This structure is that vacuum interrupter and insulation shell are integrated into an overall structure, and vacuum interrupter is cast in the epoxy resin by embedded technology, make the exposed conductive component of vacuum interrupter to external insulation, but the outlet seat is exposed outside up and down, the conductive component electrical safety performance is poor, has potential safety hazard.
Summary of the invention
The objective of the invention is at above shortcomings in the prior art, and a kind of embedded pole type vacuum load switch that provides.
The technical scheme that adopts is: a kind of embedded pole type vacuum load switch comprises pole body and spring operating mechanism.The pole body comprises vacuum interrupter, insulation shell, last outlet seat, following outlet seat, insulated tension pole and connecting lever.
Its main points are: vacuum interrupter is enclosed in the insulation shell admittedly, and last outlet seat embeds in the insulation shell, and last outlet seat upper end is provided with the isolating switch axle bed, and the lower end of last outlet seat is connected with the quiet end of vacuum interrupter.
Conductive clip is installed on the conducting rod of vacuum interrupter moved end, and the upper end that the copper conduction band is flexible coupling is connected in insulation shell with conductive clip, and the lower end that the copper conduction band is flexible coupling is connected with following outlet seat.
The vacuum interrupter operating mechanism comprises insulated tension pole and connecting lever.The right-hand member of insulated tension pole is connected with conducting rod, and the left end of insulated tension pole and the right-hand member of connecting lever are hinged, and the left end of connecting lever is connected with spring operating mechanism.Spring operating mechanism is a known technology, so repeated description not.After independently spring operating mechanism assembled, spring operating mechanism was connected with mounting panel and connecting lever.
Its advantage is: compact conformation, volume is little.Vacuum interrupter is enclosed in epoxy resin admittedly with outlet seat up and down, good insulation preformance, thus improved the useful life and the security performance of vacuum load switch.The conducting rod of vacuum interrupter moved end is flexible coupling by the copper conduction band and is connected with following outlet seat.
