    Shock absorber for circuit breaker

    DLC Series

    Product introduction

    DLC Series

    Among the high voltage circuit breakers, the shock absorber is a very important core component. There are many reasons for this wide application. Firstly, when the circuit breaker is opened and closed, the mechanism moves the open end of the arc extinguishing chamber to a limited position, and the high-speed motion will produce a violent collision, so the metal collision will inevitably rebound. The rebound reduces the opening distance of the fracture, so that the withstand voltage of the fracture will be reduced, and the closing of the fracture will fail in critical circumstances.

     

    CJAC designed a specific shock absorber for the circuit breaker. The shock absorber dedicated to the circuit breaker can absorb the collision energy generated during the machine opening, so it will minimize the rebound.

     

    In order to reduce the arcing time, the circuit breaker requires faster opening speed. Moreover, in order to reduce the impact on the opening speed of the circuit breaker, we have designed the front section of the softer damping.
