Experimentation and Research of Three-Phase Switching Synchronous Operation of Novel High Speed Switch Gear

Abstract:

This paper has proposed a novel high speed switch gear (NHSSG) whose contacts could detach quickly; it exploits the principle of the repulsion force generated by eddy effect. The NHSSG is mainly used in the hybrid switch gear (HSG) to cut off the fault circuit cooperate with the solid state thyristor switch gear (SSTSG) in a short time, so it is important for the NHSSG to motion at a certain time. Consequently, a lot of experiments have been done in different aspects to find out the impact extent of the six factors to the actuation time of the NHSSG, and the three-phase switching synchronous operation (TPSSO) experiments have been done based on the result of the analysis, and the accurate three-phase switching synchronous operation was obtained at last.
