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

The invention discloses a manual opening and closing spring operating mechanism, which includes a main energy storage sealing cylinder, one end of the main energy storage sealing cylinder is sealed and the other end is open, and the main energy storage sealing cylinders outside the three through holes are All are fixedly welded with secondary energy storage sealing cylinders, and the three secondary energy storage sealing cylinders are all connected to the main energy storage sealing cylinder body, and the three secondary energy storage sealing cylinders are all provided with secondary sealing pistons, The secondary sealing piston is fixedly connected with the opening and closing connecting rod. The main sealing piston is provided with a main sealing piston. Installed on the energy storage sealing cylinder, the energy storage device of the present invention can save labor and complete the energy storage operation at one time, the energy storage is faster, and the on-off is more decisive. The integrated settings reduce the difficulty of the operation and reduce the rate of operational errors.
