摘要（英）：

The utility model provides a 35kV and below high-voltage vacuum circuit breaker protection device. A first mounting cavity is formed in the mounting box; a mounting shaft is mounted in the first mounting cavity; the periphery of the mounting shaft is sleeved with a shaft sleeve; a first insulating plate and a first conductive shaft are mounted on the shaft sleeve; a first wire mounting shaft and afirst limiting plate are mounted on the first conductive shaft; a second conductive shaft is mounted at the lower end of the first conductive shaft; the periphery of the first conductive shaft is sleeved with an insulating sleeve; a first piston shaft and a first piston are mounted at the lower end of the insulating sleeve; a hydraulic pump is installed on the first piston, a second insulating plate is installed on the periphery of the installation shaft, a third conductive shaft is installed on the second insulating plate, a second wire installation shaft is installed on the third conductiveshaft, a fourth limiting plate is installed on the second wire installation shaft, and the center line of the second conductive shaft coincides with the center line of the third conductive shaft. The35kV and below high-voltage vacuum circuit breaker protection device is high in stability, good in safety and low in maintenance cost.
