[0002] A vacuum circuit breaker refers to a switching device that can close, carry, and break the current under normal circuit conditions and can close, carry, and break the current under abnormal circuit conditions within a specified time. Currently, most vacuum arc extinguishing circuit breakers use a single vacuum arc extinguishing chamber, and the sensitivity of vacuum arc extinguishing is relatively low;

[0003] After retrieval, the utility model with the patent publication number CN214378191U discloses an outdoor high-voltage AC vacuum circuit breaker. A transmission rod is arranged between an insulating pull rod inside a large insulating cylinder and a vacuum arc extinguishing chamber B. A tension spring is arranged above one side of the moving rod, and the other end of the tension spring is cooperatively installed with a connecting column between the inner wall of the base.
