The high voltage circuit breaker is an important power system equipment. The reliability of its running relationship with the safe operation of the entire power system. High voltage circuit breaker on-line monitoring system enables real-time monitoring of various parameters during the operation in which the circuit breaker, and the use of communication to achieve data transfer bus information. Through monitoring points, closing coil current signals to constitute the core of C8051F online monitoring unit via RS-485 serial bus will monitor information is uploaded to the master computer.

High Voltage Circuit Breaker

In this paper, mainly for the problem that high voltage circuit breaker closing at the random phase can bring hard harmfulness to the power system. We design the 35kV SF6-Phase Control circuit breaker can control speed smartly, and opens or closes with phase selection, which is equipped with the magnetic actuator. In the article, the static and transient simulation analysis which includes the load force, and carried out prototype trial and test validation. At last, the results of simulation and test is given.
