Abstract: As a key factor in the production process of coal mines, the safe operation of electrical equipment and power supply
system is very important, which directly determines the economic benefits of coal mining enterprises. This paper discussed in
detail the significance and related common protection types of the protection of electrical equipment and power supply system in
coal mines, and analyzed in detail the devices and protection measures to realize the leakage protection function, which has a
certain reference significance for the protection of electrical equipment and power supply system in coal mining.

Key words: electrical equipment; power supply system; protection function
