摘要： 介绍了煤矿井下高低压保护定值整定，从三段式电流保护、电压保护、选择性漏电保护、附加直流保护和非
电量保护等多方面研究，以三段式电流保护整定为例，科学设计煤矿井下高低压保护定值，避免因高低压保护定值设置
有误而导致煤矿供电网络出现保护拒动问题，从而确保电网系统的正常运行，为井下安全作业奠定基础。

Abstract: This paper introduced the setting of the high and low voltage protection setting value in coal mines, which was studied
from three-stage current protection, voltage protection, selective leakage protection, additional DC protection and non-electricity
protection, etc. Taking three-stage current protection setting as an example, the high and low voltage protection setting value in
coal mines was scientifically designed to avoid the protection failure of the coal mine power supply network due to incorrect settings
of the high and low voltage protection setting value, so as to ensure the normal operation of the power grid system and lay
the foundation for safe underground operations.

Key words: underground coal mine; high and low voltage; protection setting value; setting; power grid system
