Features:
      KSG-type flameproof transformers box shell, made by the steel plate welded, box 8 shell can withstand the atmospheric pressure hydraulic test; lid and box meet along the contact surface between the explosion-proof requirements;
      Cover from the steel plate, the top two cable outlet cover, outlet comprising a surface placed rubber gaskets, cables through the rubber washer and tighten the coil, the cable may be pinched by the rubber gasket to ensure sealing, the choice of cable outside diameter, must work closely with the rubber gasket, ensure the cable can be pressed, completely sealed to ensure a guaranteed cost;
      KSG-type flameproof transformer primary winding can be connected into a star connection or delta connection. Corresponding power supply voltage is 380 and 220V, or 400 and 230V (see nameplate data). Grafting required transformers and power supply will be disconnected, open the lid, in the body of the terminal board.


One. Scope and purpose
      KSG-2.5, 4.0/0.66 type flameproof dry-type transformer (hereinafter simply called transformers) for a coal mine methane and coal dust explosion hazardous areas. In AC 50Hz / 660V power supply voltage to the circuit / drill for the coal to provide 127V power supply.
Transformer according to GB3836.1-83 "electrical equipment for explosive atmospheres General requirements" GB3836.2-83 "proof electrical equipment for explosive atmospheres flameproof electrical equipment" d "" and other relevant standard design. Manufacturing and testing.
