This series mining explosion-proof type transformer is applicable in underground coal mines of three-phase indirect neutral-point earthling with explosive and dangerous gas (methane) and coal dust, and it is used to change the power supply of 10kv, 6kv into low-voltage power supply of 3450(3300v), 1200(1140v), 693(660)v, 400(1380)v, which are required in the coal mine. When the dry type transformer is used alone as mining explosion-proof dry type transformer, it can cut off lead-in wire of high-voltage power supply by pressing emergency button in emergent situation.
It realizes protection by cutting off high voltage side switch when fault like short, loss of phase, over temperature in transformer of mobile substation or fault like overload, short-circuit, electric leakage, leakage lockout, over voltage, under voltage etc in power distribution 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 and equip them on high or low voltage side of the transformer.
Rated capacity(KVA): 50, 100, 200, 315, 500, 630, 800, 1000, 1250, 1600, 2000, 2500, 3150, 4000
Primary voltage: 10kV/6kv
Secondary voltage: 3450(3300)V, 1200(1140)V, 693(660)V, 400(380)V
Short-circuit impendance(%): 4, 4.5, 5, 5.5, 6
