Title:
SPRING ACTUATOR MECHANISM FOR CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2020/164253
Kind Code:
A1
Abstract:
A spring actuator mechanism for a circuit breaker, comprising an energy storage module and an activation and deactivation module. The energy storage module can ensure sufficient energy storage in an energy storage process so as to avoid the position of a dead point. An interlocking board (203) structure is used in activation, accelerating the quick reset of an activation lever (25) and improving activation efficiency. Manual deactivation and an deactivation electromagnet (23) are used for deactivation, avoiding the situation that deactivation cannot be performed due to a deactivation failure. The spring actuator mechanism for a circuit breaker is stable in structural quality, low in cost, high in reliability and suitable for promotion and use.
