摘要： 随着煤矿现代化的进行，煤矿开采已经实现了机械化，使用了大量的机电设备。为了保证井下供电的安全性，
在供电系统中安装了保护装置。然而，在实际生产中，由于各种原因，一些保护器出现越级跳闸，严重影响了煤矿的安
全生产。因此，需要采用技术手段防止保护装置越级跳闸。介绍了目前煤矿中几种常用的防越级跳闸技术，结合实例探
讨了防越级跳闸技术的应用效果，可以为煤矿供电系统防越级跳闸提供技术指导。

Abstract: With the modernization of coal mines, coal mining have been mechanized, and a large number of electromechanical
equipment has been used. In order to ensure the safety of underground power supply, protection devices have been installed in the
power supply system. However, in actual production, due to various reasons, override trip has happed in some protectors, which
seriously affects the safety production of coal mines. Therefore, technical means should be used to prevent the protection device
from override trip. This paper introduced several commonly used anti-override trip technologies in coal mines, and discussed the
application effect of anti-override trip technology in combination with examples, which can provide technical guidance for the
anti-override trip of the coal mine power supply system.

Key words: coal mining; power supply system; anti-override trip
