Mining explosion-proof mobile substation

Mining explosion-proof mobile substation is designed to used in the mines with methane, coal dust and the danger of explosion. It could be used in the 3-phase power system with the rated frequency of 50Hz, the first voltage of 6kV or 10kV and the neutral ungrounded. It’s used to supply the power for the power equipment and electric appliances in the mines.

When 3-phase power wire (6kV or 10kV) is connected with the input ports of A, B and C of the dry-type transformer, according to the principles of electromagnetic induction, the power voltage would be transferred into the voltage required by the power equipments and the electric appliances (1200V or 693V, 693V or 400V)
