Abstract：This paper analyzes the present research status of vacuum circuit breaker, and points out the low reliability of the existing vacuum circuit breaker with single opening and closing coil, and puts forward a new structure of fast vacuum circuit breaker with 10kV double opening and closing coil. This type of circuit breaker has two separate opening and closing coils, which acts on the metal disc of the circuit breaker, and ensures the reliability of the breaking. Then, the electromagnetic repulsion force of the metal disc of the circuit breaker is analyzed mathematically.
