    Abstract: In order to reduce the response time of the motor operating mechanism driving the motor in the opening and closing operation of the circuit breaker, increase the opening and closing speed of the circuit breaker and improve the contact oscillation of the circuit breaker. This paper proposes a boost converter technology using energy storage capacitors in the control system of the motor operating mechanism. Aiming at the technical requirements for opening and closing of the 126 kV vacuum circuit breaker, a switched capacitor bank is used as a boost device, and the capacitor switching technology is used to change the energy storage and release mode of the circuit breaker for opening and closing operations, and to control the movement process of the moving contact of the circuit breaker in sections.In this paper, under the condition of the switched capacitor bank and the ordinary energy storage capacitor, the opening and closing experiment of the motor operating mechanism of the 126 kV vacuum circuit breaker is carried out. The experimental results certificate that, comparing with the experiment of opening and closing characteristics using ordinary energy storage capacitors, the motor control system based on the switched capacitor bank can effectively speed up the opening and closing rate of the circuit breaker. In addition, it can improve the contact bounce of the circuit breaker.
    Key words: switched capacitor bank; vacuum circuit breaker; control system; opening and closing time
