Manual opening and closing spring operating mechanism and vacuum circuit breaker thereof

Abstract

The invention discloses a manual opening and closing spring operating mechanism, comprising a main energy storage sealing cylinder, wherein one end of the main energy storage sealing cylinder is sealed and the other end of the main energy storage sealing cylinder is opened; secondary energy storage sealing cylinders are fixedly welded on the main energy storage sealing cylinder outside three through holes; the three secondary energy storage sealing cylinders are all communicated with the main energy storage sealing cylinder body; secondary sealing pistons are arranged in the three secondary energy storage sealing cylinders; the secondary sealing pistons are fixedly connected with an opening and closing connecting rod; a main sealing piston is arranged in the main energy storage sealing cylinder; and an energy storage spring is fixedly installed on the side, close to a telescopic rod, of the main sealing piston. According to the energy storage device of the manual opening and closing spring operating mechanism, labor can be saved, and energy storage operation can be completed at a time, and energy storage is faster, and on-off is more convenient, meanwhile, a traditional energy storage pull ring and an opening and closing pull ring are integrally arranged, and the operation difficulty is reduced, and the operation error rate is reduced.

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned intelligent high-voltage dual-power vacuum circuit breaker still has obvious defects in the use process: 1. The above-mentioned device needs to store energy during the opening and closing operation, and the energy storage rod needs to be pulled repeatedly during manual energy storage. The circuit processing is not fast enough. At the same time, most of the circuit breakers currently on the market use the above energy storage methods; 2. The energy storage ring and the opening and closing ring of the above device are set separately, and energy storage is required when opening and closing operations After the on-off, the power workers need to aim at the energy storage ring hole on the ground and then open and close the hole, which increases the difficulty of operation and prolongs the processing time
