Flameproof and intrinsically safe permanent magnet vacuum feeder
key word:
It is suitable for coal mine in explosive environment, in the power supply system with rated frequency 50Hz, rated voltage 1140V, 660V, rated current 630A and below the three-phase neutral point is not grounded, as the main switch or separate switch of the distribution system, and can also be used as the infrequent start and stop of large capacity motor. Connected with KJ series underground coal mine power grid monitoring system, it can realize remote automatic control, monitoring and monitoring of power equipment, and realize modern management such as unattended substation.
