Abstract

The invention discloses a circuit breaker device which comprises a permanent magnetic mechanism shell, a movable iron core, a shifting fork, a movable contact, a static contact, a shielding box, an optical fiber temperature sensor, a mechanism action sensor and a contact action sensor. The state of the circuit breaker is monitored through the mechanism action sensor, the contact action sensor and the optical fiber temperature sensor, and the problem that the state of the circuit breaker cannot be monitored in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker device. Background technique [0002] The mainstream circuit breakers currently on the market only function as breaking, short-circuiting and connecting to the DC traction power supply system, and lack the status monitoring of the circuit breaker itself. It can only cooperate with the DC integrated measurement and control protection device to detect the opening and closing speed, bounce and short-circuit current of the circuit breaker. It is impossible to judge the health status of the circuit breaker after long-term operation, as well as the remaining life of the circuit breaker, which increases operation and maintenance. The difficulty of personnel work and the cost of operation and maintenance. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the prior art, a circuit breaker device provided by the present invention ...
