Product Description
Purposes
QBZ-2×120(80)/1140(660, 380)SF mining explosion-proof Ventilator with dual-power vacuum electromagnetic starter is ideal for use in AC 50Hz, 1140V, 660V or 380V power supply system in coal mines for automatic switching of double-power-supply and double-blower to realize that the two power supplies work together, and to ensure both working blower and standby blower are available for switching in operation, in order to a long-period ventilation in mines. Therefore, it is an ideal ventilation and power supply equipment for coal mines, especially for mines with high concentration of gases.
Technical features
Two independent power supplies and two independent explosion-proof chambers;
Double channel indication of power supply working, stop and examination; Parameters With power, run, slip of the fault protection, maintenance and other display;
Protective functions of overload, short-circuit, phase loss, current leakage, under voltage and overvoltage etc;
Switching time: 0-10s adjustable;
Protective function of gas, wind and electricity interlocking;
Total four outlets, each power has two contactors;
