摘要
针对煤矿供电系统中出现的越级跳闸,造成矿井大面积停电、瓦斯集聚等安全问题。本文从越级跳闸形成的机理入手进行研究,分析了煤矿供电线路的特点及防爆开关自身机构缺陷,并提出基于GOOSE的闭锁短路保护,并在凤凰台煤矿进行实施,有效的防止越级跳闸的发生,提高了煤矿供电系统的稳定性。
According to override trip in coal mine power supply system, it resulted in mine large area blackout, gas concentration and other security issues, from the formation of leapfrog trip mechanism, the characteristics of the coal mine power supply line and the explosion-proof switch mechanism defects were analyzed in the paper, and the lock short-circuit protection based on goose was proposed and was implemented in Phoenix coal mine, which was effective to prevent the occurrence of override trip, and improve the stability of coal mine power supply system.
