摘要： 为了保障矿井电力系统的安全运行，设置了多级断路器跳闸保护。但在很多情况下，断路器会出现越级跳闸，
这给矿井的安全生产带来了很大的威胁。针对矿井保护的越级跳闸问题，分析了传统防越级跳闸方法的优缺点，并结合
现场情况分析了基于电力监控系统的防越级跳闸方案，可以为矿井电力系统的安全运行提供一定的参考。

Abstract: In order to ensure the safe operation of the mine power system, the multi-level breaker trip protection is set up. But in
many cases, the circuit breaker will trip over the level, which brings a great threat to the safety of production of the mine. In view
of the problem of overtrip of mine protection, this paper analyzed the advantages and disadvantages of the traditional anti-overtrip
methods, and combined with the field situation, analyzed the scheme of anti-overtrip based on the power monitoring system, which
can provide a certain reference for the safe operation of the mine power system.

Key words: mine; power supply; anti-overtrip; power monitoring system
