摘要： 在煤矿供电系统中，装有多级保护装置。然而，在生产过程中，由于保护装置的原因或其他原因，保护装置
会发生越级动作，非常不利于矿井的安全生产。分析了煤矿供电系统发生越级跳闸的原因，并提出了一些合理地预防越
级跳闸的措施，从而保证煤矿的安全高效生产。

Abstract: Multi-level protection devices are installed in the coal mine power supply system. However, in the production process,
due to the protection device or other reasons, the protection device will have over-level action, which is very unfavorable to the
safe production of the mine. This paper analyzed the reason for the over-level trip of the coal mine power supply system, and put
forward some reasonable measures to prevent the over-level trip to ensure the safe and efficient production of the coal mine.

Key words: coal mine production; power supply system; over-level trip
