Vacuum Circuit Breaker With PT is a device that integrates a voltage transformer (PT) on the basis of a vacuum circuit breaker. The vacuum circuit breaker itself is a circuit breaker whose contacts are closed in a high vacuum bubble, and its high vacuum environment is used as an arc extinguishing and insulating medium. The voltage transformer is used to monitor the voltage of the power system to ensure the stable operation of the system. By combining the two, the device can not only perform circuit closing, bearing and breaking operations, but also monitor the voltage situation in real time.
