煤矿供电系统防越级跳闸技术研究

Technologies of Preventing Leapfrog Trip of Coal Mine Power Supply System

煤矿开采过程中,供电系统的稳定、安全运行极其重要,直接关系到煤矿设备的正常运行。然而,煤矿供电系统在运行过程中会发生越级跳闸,导致煤矿生产无法顺利进行,严重影响了煤矿的经济效益。主要详细分析了煤矿供电系统越级跳闸的影响因素,探讨了几种防越级跳闸技术。这些技术的应用可以有效控制越级跳故障的发生,有利于供电系统的长期稳定运行。

In the process of coal mining,the stable and safe operation of power supply system is extremely important,which is directly related to the normal operation of coal mine equipment.However,leapfrog trip may occur in the coal mine power supply system in the process of operation,so that the coal mine production can not proceed smoothly,which seriously affects the economic benefits of coal mine.The factors affecting leapfrog trip of coal mine power supply system were analyzed in detail,and several technologies of preventing leapfrog trip were discussed.The application of the technologies can effectively control the occurrence of leapfrog trip fault,which is conducive to the long-term stable operation of power supply system.
