The scope and purpose
KSG series flameproof dry-type transformers (hereinafter simply referred transformer) applies to coal mine methane and coal dust explosion hazard. AC power line 50Hz / voltage to 660V in the coal drilling or lighting provide 380V, 220V, 127V, 36V and other power.
Transformer design according to the relevant standards GB3836.1-83 "explosive environment with explosion-proof electrical equipment General requirements" GB3836.2-83 "explosion-proof electrical equipment for explosive atmospheres flameproof electrical equipment" d "" and so on. Manufacturing and testing.
The main characteristics of the product]
KSG type transformer flameproof enclosure, the Department is made of welded steel plate, the enclosure can withstand 8 atmospheric pressure hydraulic test; along the contact surface between the lid and the box in line with explosion-proof requirements;
Cover made of sheet steel, the above two sets of cable outlet, outlet sleeve surface placed rubber gaskets, cables through the rubber gasket, after tightening the coil may be made by pressing the cable to ensure the rubber gasket seal, the choice of cable outer diameter, must cooperate closely with the rubber gasket, 务使 cable can be pressed, completely sealed to ensure a guaranteed performance;
KSG type flameproof high voltage winding of the transformer can be connected into a star connection or delta connection. The corresponding power supply voltages of 380 and 220V, or 400 and 230V (see nameplate data). When changes need to be connected to the transformer and the power is turned off, open the lid, in the body of the terminal plates.
