Research on Stroke Detection Technology for High-Voltage Distribution Devices in Coal Mine

The continuous advancement of intelligent technology in coal mines has raised increasingly high demands for the reliability and safety of power grids. Based on an analysis of the structure and voltage levels of coal mine power supply systems, a stroke detection system for high-voltage distribution devices in coal mines has been designed, centered around a PIC microcontroller and linear displacement sensors. This system enables real-time monitoring of the movement of the dynamic contacts in high-voltage distribution devices, providing valuable reference for the design of such equipment in coal mines.
