Abstract
The utility model discloses a fixedly embedded pole for a vacuum load switch. The fixedly embedded pole comprises a vacuum arc-extinguishing chamber, an insulation casing, an upper wire outgoing seat and a lower wire outgoing seat. The stationary end of the vacuum arc-extinguishing chamber is fixedly connected with the upper wire outgoing seat, an isolation switch shaft seat is arranged at the upper end of the upper wire outgoing seat, the movable end of the vacuum arc-extinguishing chamber is fixedly connected with the lower wire outgoing seat, and the vacuum arc-extinguishing chamber, the lower wire outgoing seat, the upper wire outgoing seat and the isolation switch shaft seat arranged at the upper end are fixedly embedded in the insulation casing. A conductive clamp, a conductive pole and an insulation pull rod are arranged in the insulation casing at one side of the movable end of the vacuum arc-extinguishing chamber, the conductive clamp is mounted on the conductive pole connected with the movable end of the vacuum arc-extinguishing chamber, and the conductive clamp is flexibly connected with the lower wire outgoing seat through a copper conductive belt. The insulation pull rod is connected with the conductive pole, and the conductive pole is connected with a crank arm on an operating mechanism of the vacuum load switch through the insulation pull rod. According to the fixedly embedded pole structure adopted by the utility model, the insulation property and the resistance to severe environment of the vacuum load switch are greatly improved, the structure is compact, the size is small, the service life is long, and the safe and stable working of the vacuum load switch is guaranteed.
Description
Technical field
The utility model relates to technical field of vacuum switches, particularly relates to the vacuum load switch pole.
Background technology
Vacuum load switch is widely used in the switch cubicle, and vacuum load switch mainly is comprised of conduction major loop and operating mechanism.The conduction major loop has developed into open design the pole type structure at present.Pole is vacuum interrupter to be cast in the epoxy resin solid insulating material form pole, the insulation of pole makes its external environment be reduced to minimum to the impact of vacuum interrupter, also greatly improved the dielectric strength of vacuum load switch, but the conductive parts that the up and down wire outlet seat that has is relevant with vacuum load switch is exposed outside, the conductive parts electrical security is poor like this, has potential safety hazard.
The utility model content
The technical problems to be solved in the utility model is, a kind of compact conformation is provided, and volume is little, and good insulation preformance improves the vacuum load switch pole of useful life and security performance.
The technical scheme that adopts is:
The vacuum load switch pole comprises vacuum interrupter, insulation shell, upper wire outlet seat, lower wire outlet seat.The quiet end of described vacuum interrupter is fixedly connected with wire outlet seat, upper wire outlet seat upper end is provided with the isolating switch axle bed, the moved end of vacuum interrupter is fixedly connected with lower wire outlet seat, and the isolating switch axle bed that described vacuum interrupter, lower wire outlet seat, upper wire outlet seat and upper end are provided with is enclosed in the insulation shell admittedly.Be provided with conductive clip, conducting rod, insulated tension pole in the insulation shell of described movable end of vacuum arc extinguishing chamber one side, on the conducting rod that conductive clip is installed in movable end of vacuum arc extinguishing chamber is connected, conductive clip is by the copper conduction band lower wire outlet seat that is flexible coupling.Insulated tension pole connects conducting rod, is connected with connecting lever on the vacuum load switch operating mechanism by insulated tension pole.
The utility model adopts pole mechanism, has greatly improved insulation property and the anti-adverse environment performance of switch, compact conformation, and volume is little, and long service life is guaranteed the switch safe and stable operation.
