Quick vacuum circuit breaker

The invention relates to a quick vacuum circuit breaker. The quick vacuum circuit breaker is characterized in that the tail end of a movable conducting rod is connected with one end of an insulator (2), the other end of the insulator (2) is connected with one side of an opening coil (3) by a connecting rod, the other side of the opening coil (3) is connected with one side of a closing coil (5) by a connecting rod, the other end of the closing coil (5) is connected with a disc spring by a connecting rod, and an eddy current disc (4) is further mounted on the connecting rod between the opening coil (3) and the closing coil (5); a second wiring terminal of the opening coil (3) and a second wiring terminal of the closing coil (5) are respectively connected with two output ends of a selector control switch (K), and the quick vacuum circuit breaker further comprises a first energy storage capacitor (C1) and a second energy storage capacitor (C2) which are serially connected with each other. The quick vacuum circuit breaker has the advantages that the closing time can be about 12ms, and the opening time can be within a range of 5ms under the control.
