    Abstract: Status of microcomputer protection device for mine-used high-voltage explosion-proof switch was introduced from aspects of hardware structure and basic functions. Some problems of the microcomputer protection device for mine-used high-voltage explosion-proof switch were pointed out, such as lack of uniform standards, low accuracy of selective leakage protection, uncomprehensive performance of anti-override trip, lack of fault diagnosis function and poor communication reliability. Development trends of the microcomputer protection device for mine-used high-voltage explosion-proof switch were proposed, which included unified technical standards, selective leakage protection based on multi-criteria fusion, anti-override trip based on intelligent substation, fault diagnosis of mine-used high-voltage explosion-proof switch and combination of multiple communication modes.
