Automatic control device for vacuum circuit breaker on electric distribution network

The invention relates to an automatic control device for a vacuum circuit breaker on an electric distribution network. The control circuit of the device mainly comprises a signal acquisition and working power supply unit, a logic judgment unit, a man-machine interface and an execution mechanism which are connected. The control device can be matched with the vacuum circuit breaker on the electric distribution network; when the electric distribution network fails, logic judgment can be performed according to acquired information and a failure area is quickly identified and isolated; meanwhile, the normal power supply of a non-failure area is recovered, power failure areas caused by the failure are greatly reduced and power failure time is shortened; and work amount is greatly reduced and the safety factor of field operation is improved. The control device has a simple structure, a reasonable design, safe and reliable performance and low cost, and is flexible and convenient to operate and convenient to install and maintain.
