Abstract
A double-body transformer with a hoisting device relates to the field of transformers. The transformer lifting device is mainly designed for solving the problem that a box cover is easy to deform when the existing transformer is lifted. The transformer comprises an oil tank, wherein two transformer bodies of a voltage regulating transformer and a series transformer are arranged in the oil tank, the two transformer bodies are connected together by a cold pressing connector, a tank cover is arranged at the top of the oil tank, the upper ends of two transformer pull screws are connected to angle steel on the lower surface of the tank cover, and two lifting devices are welded on the high-voltage sides of the two transformer bodies; the lifting device comprises a lifting screw rod, the lower end of the lifting screw rod is welded on the upper clamping piece, the upper end of the lifting screw rod is in threaded connection with the device body connecting block, a flat gasket is arranged between the device body connecting block and the box cover, the screw rod at the top of the device body connecting block extends out of the flat gasket and the box cover, and a nut is screwed outside the screw rod; the box cover is welded with a flange, the outer surface of the nut is covered with a protective cover, and the protective cover is in threaded connection with the flange. The advantage is that the weight of hoisting the double-ware body can not cause the case lid to warp because of the bearing.
