Single-phase oil-immersed transformer and special iron core therefor

Abstract

The invention provides a single-phase oil-immersed transformer and a special iron core therefor. The single-phase oil-immersed transformer comprises a box body with a box cover, an iron core, a radiating pipe, an oil conservator, a lifting mechanism, a power mechanism and an oil tank, wherein the iron core is a single-frame dual-core column with a groove, is arranged at the center of the box body and is immersed by an oil body; a coil is led out of the box cover; a high-voltage insulating sleeve and a low-voltage insulating sleeve respectively sleeve a lead; the radiating pipe is arranged on the side wall of the box body; the oil conservator is arranged at the upper end of one side of the box body; the lifting mechanism is arranged below the iron core; the bottom end of the lifting mechanism is fixedly connected with the box body; the power mechanism is connected with the lifting mechanism; the oil tank is connected with the power mechanism; and the oil tank is arranged outside the box body. The single-phase oil-immersed transformer can drive the lifting mechanism to take out the iron core by taking the oil in the box body as a power source through the power mechanism and stores the oil in the box body into the oil tank, so that maintenance of the iron core and oil-change operation are facilitated; the cost is saved; and the maintenance efficiency is also improved.

Description

technical field [0001] The invention relates to the technical field of electric power transmission equipment, in particular to a single-phase oil-immersed transformer and its special iron core. Background technique [0002] The main components of the transformer are iron core and coil, and the iron core plays the role of magnetic conduction and skeleton in the transformer, and its processing quality directly affects the quality of the transformer. At present, transformer iron cores generally adopt laminated iron core structure, which is different from the manufacture of small transformer iron cores in the manufacturing process, mainly reflected in the stacking and lifting methods of iron cores. Transformer iron cores generally only need to be placed on the working platform After the stacking is completed, it can be lifted directly from the working platform with a sling so that it can be changed from a horizontal position to a vertical position. During the lifting process, it...
