Design of Motor Protection Systems for Explosion-proof Coal Mine Digging Device

In order to improve the safety level of motors in explosion-proof coal mine digging device and adapt to the development needs of intelligent coal mines, an explosion-proof coal mine digging device motor protection system based on the main controller is proposed. Based on the analysis of the status of coal in the national economy and the current situation of coal mine safety production, the motor protection system of coal mine explosion-proof digging device is designed, and the overload detection module and leakage detection module are designed in detail to provide the basis for the development of intelligent technology of coal mine explosion-proof digging device motor.
