Description

Technical Field

[0001] The utility model relates to a disc spring device for high - voltage opening. Background Art

[0002] The high - voltage opening spring device is an important component in a high - voltage circuit breaker. Its main function is to provide the necessary force when the circuit breaker needs to open. When the circuit breaker receives an opening signal, the opening spring releases the stored energy, driving the moving contact of the circuit breaker away from the static contact, thereby realizing the opening operation of the circuit breaker. In the existing disc spring device for high - voltage opening, the protection of the disc spring is relatively weak. After multiple openings, the end of the disc spring is easily affected by factors such as vibration, resulting in dislocation and position deviation, which greatly reduces the energy storage effect, there is a hidden danger that the opening action is not in place, and the service life of the disc spring is not high. Therefore, the existing disc spring device for high - voltage opening is improved and optimized. Summary of the Utility Model

[0003] To solve the above problems, the technical problem to be solved by the utility model is to provide a disc spring device for high - voltage opening.

[0004] The technical solution adopted by the disc spring device for high - voltage opening of the utility model is as follows: It is characterized by including a main shaft assembly, a disc spring fixing plate, a disc spring, and an energy storage turntable that are sleeved on the main shaft assembly and arranged in sequence from top to bottom. The main shaft assembly drives the energy storage turntable to rotate. The disc spring is provided with a disc spring inner through - hole, which includes disc spring inner positioning feet arranged inside, disc spring contraction parts arranged at intervals around the disc spring inner through - hole in a ring shape, and disc spring outer docking feet arranged outside. The disc spring outer docking feet are provided with docking foot driving ports inside. The energy storage turntable includes a turntable main body for placing the disc spring, and the turntable main body is vertically bent to form a turntable docking block inserted into the docking foot driving port.

[0005] The disc spring fixing plate includes a fixing plate main body covering the disc spring. The fixing plate main body is provided with a fixing plate through - hole. At the fixing plate through - hole on the back of the fixing plate main body, there is a fixing plate perimeter arranged in the disc spring inner through - hole.
