The phase-control switching technology of circuit breakers, which provides an important technical approach for smart grid construction, can effectively mitigate the transient caused by switching operations in power systems. The key technology of phase selections with vacuum switches is to control the operating characteristic of permanent magnetic actuators in vacuum switches, so as to realize a stable operating time for vacuum switches under different environmental conditions. This paper proposed a new type of control-driven program for vacuum switches with permanent magnetic actuators using the fuzzy self-adaptive PID control technology. And the design of this new type of control-driven system for permanent magnetic actuators in vacuum switches was accomplished based on the TMS320LF2407A processor. According to the experimental results, the system can keep the switching time error within ± 0.25 ms under different environmental conditions.
