Abstract: The theory, realization and application of permanent magnetic synchronous switch
are proposed in this paper. High-speed and high-precision A/D sampling and multi-processor
systems is designed in the system. It can be used to monitor and analyze the electrical parameters of 10KV power net, and realize the dynamic selection of the best closing time for circuit breakers according to control strategy. The system parameters and states can be set and checked by the keyboard, and the results can be displayed on the LCD. Result shows that the system can reduces the transient processes during the close processes of circuit breakers compared with traditional methods, so it can be applied for practical usages.
Key words: permanent magnetic mechanism; synchronous switch; multi-processor
