Function
This series mining explosion-proof type high-voltage vacuum distribution device is applicable in underground coal mines with explosive and dangerous gas (methane) and coal dust, it is equip ped with BXB7-800/1140(660) mining explosion-proof type low-voltage protective box and used on the high and low voltage side of dry type transformer for mining explosion-proof type mobile substation, there it is used as high and low voltage distribution switch for explosion-proof type mobile substation and protector to the off the high-voltage power supply when fault happens to low-voltage side or transformer.
Characteristics
Real-time display for each kind of work data with simple and straight forward parameter setting;
Standard RS485 communication interface;
Various kinds of protective functions for overload, short circuit, under voltage, over voltage, loss of phase, electric leakage, three-phase unbalance etc.
It realizes cutting off power supply on high-voltage side for fault on low-voltage side by being equipped with mining explosion-proof type low voltage protective box as mobile substation.
