The correct switching of the power protection pressing plate is directly related to whether the relay protection equipment normally operates, and the wrong switching state can bring huge threats to power safety, wherein the misoperation of the pressing plate comprises error switching, missing switching and missing switching. Therefore, how to prevent the power protection pressing plate from being mistakenly thrown or withdrawn becomes a main problem of the current power protection pressing plate.
