BXB-Y Mining Explosion Proof Intrinsically Safe Low Voltage Protection Box
Use: The mining explosion proof low-voltage protection box used in movable transformer substation is used in explosive and dangerous coal mine where is filled with methane and coal dust, installed at low voltage side of movable transformer substation, it is used with our KJG series mining explosion proof intrinsically safe high voltage vacuum distribution device, form an ideal movable transformer substation system with low voltage fault breaking high voltage function.To supply power system with 3300V,1140V,660V,380V/50Hz,rated current is below 1600V,has protection functions of electric leakage, leakage latch, short-circuit, overload, phase balance, wind and electricity latch, etc. It can automatically cut off power when supplying power circuit is over-load, short-circuit, phase break or leakage. Over-current protection has inverse time-limited characteristics,proximal output short-circuit adopt no voltage rele asing big current protection circuit.
We are paying effort to prompt the development of explosion proof industry.We will bring innovation and surprise for the industry.
We are ready to face the challenge
Making our dream come true....
