Analysis and Optimization of Anti-bouncing Circuits for Circuit Breakers
The working principles of operation box anti-bouncing circuit and circuit breaker mechanism anti-bouncing circuit are elucidated.The differences between operation box anti-bouncing circuit and circuit breaker mechanism anti-bouncing circuit are analyzed.A case of mismatch of anti-bouncing circuit component parameters is discussed,and the improvement measures are pro-posed to optimize the anti-bouncing circuit,such as series connection of resistor and series connection of open position auxiliary contact of circuit breaker in the anti-bouncing circuit,which prevent multiple opening and closing of circuit breaker in a short pe-riod of time and provide a more solid guarantee for the safe and reliable operation of power system.
