KBSG- /10(6)



  • 1. Function
    This series mine explosion-proof type transformer is applicable in underground coal mines
    of three-phase indirect neutral-point earthing 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(3300)V , 1200(1140)V , 693(1660)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.

    2. Model



    3. Characteristics
    3.1 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, leakafe lockout, over voltage , under voltage etc in power
    distribution system happens.
    3.2 Standard RS485/232 communication interface for high-low voltage switch.
    3.3 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 .
