Mine flameproof high voltage leakage protection device ZBL-H

The device is suitable for the underground coal mine with explosive dangerous gas and coal dust, installed in the 10(6)kV underground central substation, substation in the mining area, using centralized synchronous real-time sampling, distributed control structure of high voltage selective leakage protection, suitable for the neutral point is not grounded or grounded by the arc suppression coil power supply system. It can quickly and accurately find the single-phase grounding fault line, and locate the fault within 20 meters, prevent the power system from leakage and tripping, and avoid large-scale power outage accidents. With optical fiber communication interface, it can access the power monitoring system through optical fiber to realize synchronous real-time remote monitoring.
