Embodiment:
As shown in Figure 3: a kind of intelligent vacuum circuit breaker speed on-line monitoring method, this method may further comprise the steps:
A. the intelligent vacuum circuit breaker device for monitoring speed is connected on the vacuum circuit breaker, the sensor of speed on-Line Monitor Device is arranged in the vacuum circuit breaker insulator;
B. described sensor is gathered in real time to the vacuum circuit breaker trip information, then to signal amplify, conversion process, and transfer to control module;
C. described control module is analyzed contrast to the trip information of vacuum circuit breaker;
D. the information of handling is directly fed back on device for monitoring speed by the acousto-optic mode.
It is vacuum circuit breaker speed on-line monitoring that described control module is analyzed contrast to the trip information of vacuum circuit breaker: pressure transducer is installed in isolating switch, the test force value changes when the isolating switch on/off switch, by sensor transmissions to controller, the power value parameter that receives calculates the divide-shut brake speed parameter by central processing unit, and with default divide-shut brake speed alarming value relatively, in time send alarm.
