Application of power monitoring and override trip prevention system in coal mine
LIU Bo
Abstract：In order to solve the short-circuit fault override trip, caused by poor environment of underground coal mine, complex power supply line, multi joint, resulting in underground blackout, the necessity of monitoring and inspecting was explained for coal mine power supply system. The problems in coal mine power supply system of Wuhai Coal Group were introduced, which was the matching difficulty of switch protection setting, as the large-amount switches purchased in different coal mines, were of different batches or different manufacturers. A solution scheme was proposed using the power monitoring and override trip prevention system toguarantee the reliability and safety of coal mine underground power supply.
