Abstract：The traditional protection devices achieve protection and control functions based on a variety of relays Coordination, the successful application of microcomputer relay protection device greatly simplifies protection and control loop and reduces loop failure rate, generally getting recognition in the breaker applications. But the traditional protection devices and microcomputer relay protection device is designed and developed for high voltage circuit breaker application, as the design reasons of electrical contactor control schematic, the FC switch tripping miss operation in Huangdao Power Plant the No.5 and the No.6 running, causing the switch burned phenomenon. Due to the problem, this paper carry out a more detailed analysis analyses for electrical control principle of high-voltage vacuum contactors with the maintaining mechanical type and proves reliable solution.
