This series mine explosion-proof type mobile substation is a mobile complete set of powerdistribution and transformer device. It is applicable in underground coal mines withexplosive and dangerous gas(methane) and coal dust, and is used to change the powersupply of 10kV, 6kV into low-voltage power supply of 3450(3300)V, 1200(1140)V, 400(380)V,which are required in the coal mine, and it also offers safety protection. It is combined withthree parts, namely, mining explosion-proof type high-voltage vacuum power distributiondevice, dry type transformer for mining explosion-proof type mobile substation, miningexplosion-proof type low-voltage protective box.
It realizes protection by cutting off high voltage side switch when fault like short, loss ofphase, over temperature in transformer of mobile substation or fault like overload,short circuit, electric leakage, leakafe lockout, over voltage , under voltage etc in powerdistribution system happens.
Standard RS485/232 communication interface for high-low voltage switch.
Users can select high voltage load switch and low voltage vacuum feeder switch andequip them on high or low voltage side of the transformer.
