Breaker for realizing on-line monitoring of vacuum degree of vacuum explosion chamber

The present utility model discloses a breaker for realizing on-line monitoring of vacuum degree of a vacuum explosion chamber. The breaker comprises a monitoring device arranged on the edge of a shielding cover of the vacuum explosion chamber, the monitoring device is connected with a control device through an optical fiber transmission line, the control device is used for receiving vacuum explosion chamber vacuum monitoring signals emitted by a sensor and comparing the signals with data set in the control device, displaying in real time and giving out a vacuum explosion chamber leakage alarm; a monitoring method is realized through arranging the voltage sensor on the edge of the shielding cover of the vacuum explosion chamber to detect the level change of the shielding cover, thus pressure change of gas inside the vacuum explosion chamber can be monitored, and the method comprises high voltage area monitoring and safety area judging. In the beaker for realizing on-line monitoring of vacuum degree of the vacu
