Device and method for synchronously lifting two bodies of transformer

Abstract

The invention relates to a device and method for synchronously lifting two bodies of a transformer, and belongs to the technical field of transformer manufacture. The device adopts the technical scheme that a main transformer boy iron core lower clamping piece (12) at the lower part of a main transformer body (4) is fixed on a transformer body lower part connecting steel plate (6); an auxiliary transformer body iron core lower clamping piece (13) and an insulating padding plate II (17) are fixed on the transformer body lower part connecting steel plate; the top of the main transformer body is fixed on a main body iron core upper clamping piece (8); the top of an auxiliary transformer body (5) and an insulating padding plate I (7) are fixed on the main body iron core upper clamping piece through an upper part connecting bracket (3); a synchronous lifting point (2) is connected with a lifting beam (1) at the upper part through a suspension cable. The device integrally lifts the main transformer body and the auxiliary transformer body, can realize the fact that two independent transformer bodies provided with leads are synchronously lifted and put into a transformer oil tank, avoids repeated dismounting of the leads between the two independent transformer bodies, shortens the production manufacturing cycle of products, and effectively guarantees the insulation distance between the two independent transformer bodies.

Description

technical field [0001] The invention relates to a synchronous lifting device and method for double transformer bodies, belonging to the technical field of transformer manufacturing. Background technique [0002] In recent years, with the rapid development of power grids and power plants, more and more transformers need to adopt a structure in which two independent bodies are installed in the same oil tank. The two independent bodies of the transformer need to be connected by lead wires (formed lead wires). At the same time, in order to effectively ensure the electrical insulation distance, the relative position between the two independent bodies should be strictly controlled. Due to the limited space inside the transformer, it is necessary to connect the lead wires (formed lead wires) outside the fuel tank between the two independent bodies. After the lead wires are assembled, open the lead wires, lift the two bodies separately, put them into the fuel tank, and then enter th...

AI Technical Summary

Problems solved by technology

Background Art The separate lifting method of two device bodies requires repeated disassembly and assembly of the lead wires (formed lead wires) between the two device bodies. The operation is cumbersome, and the production cycle is long, which will also increase safety hazards in terms of electrical insulation.
