Abstract: As the power source of mine production, the operation safety of power supply system is of great significance to ensure
the continuous and safe production. Taking this as a starting point, this paper analyzed and probed into the optimization of antioverride
trip technology of underground power supply system. Firstly, it made a comprehensive analysis of the operation principle
of the anti-override trip, and on this basis, it put forward the optimization measures of the anti-override trip system, then made a
comprehensive analysis of the structure of the optimized power supply system, and gave a comprehensive overview of the
precautions to ensure the full and effective play of the anti-override trip protection function of the power supply system. The
practical application shows that the optimized anti-override trip technology has a good effect, which not only greatly reduces the
number of failures, but also significantly improves the effectiveness of power supply system operation and increases the comprehensive
benefits of the mine.
