Abstract: Power supply system is the power source of mine production, and its operation effectiveness and stability have a significant
impact on the comprehensive benefits of mine production. Based on the analysis of the overall design of the line protection
device, this paper analyzed the function of the protection device, and discussed its hardware circuit design and logic, hoping to
provide reference for the development of similar projects in other mines.
