摘要：This paper introduces the development history of vacuum circuit breakers. According to the low reliability of the vacuum circuit breakers with single opening and closing coil, this paper proposes a new type of 10kV quick vacuum circuit breaker with double opening and closing coils. This new type circuit breaker has two opening and closing coils, which together act on the metal disc of the circuit breaker to ensure the reliability. Then, the electromagnetic repulsion force of the metal disk is deduced using the equivalent calculation method. On this basis, mathematical analysis and calculation are performed on the electromagnetic repulsion of the circuit breaker's metal disc. Thereby the reliablity of the quick vacuum circuit breaker with double opening and closing coils is proved.
