Mine explosion-proof low voltage side protection box for mobile substation is applicable inunderground coal mines with explosive and dangerous gas (methane) and coal dust, it isequipped on low voltage side of dry type transformer for mine explosion-proof type mobilesubstation, it is a mine explosion-proof type mobile substation when it is combined with drytype transformer for mine explosion-proof type mobile substation and mine explosionprooftype high-voltage vacuum distribution device. It can detect each kind of fault of lowvoltagenetwork and send the fault signal to high-voltage vacuum distribution device forcutting off high-voltage power supply.
Real-time English display work data such as parameter of three-phase current, threephasevoltage, insulating resistance etc.
Standard RS485 communication interface.
Various kinds of protective functions for overload, short circuit, under voltage, overvoltage, loss of phase, electric leakage, three-phase imbalance, fan and power supplylockout, gas lockout etc.
It realizes cutting off power supply on high-voltage side for fault on low-voltage side bybeing equipped with mine explosion-proof type high-voltage vacuum distributiondevice as mine explosion-proof type mobile substation.
