Method for integrally supporting coil inner paper tube of transformer

Abstract

The invention relates to a method for integrally supporting a coil inner paper tube of a transformer, and belongs to the technical field of transformers, wherein the method is applicable to supporting operation in the integral sleeve installation process of coil inner paper tubes of the transformers, electric reactors and mutual inductors. According to the technical scheme, a tool is composed of a clamping part (1), a lead screw inserting-connecting part (2), a lead screw thread buckle (3) and a supporting shaft (4), a compression flange of the tool is fixedly connected with a cantilever of a coil lifting tool, the coil inner paper tube is clamped into two supporting pieces of the tool supporting shaft, after a coil is lifted, the supporting force of the tool is adjusted, the coil inner paper tube is supported in place, and the tool does not loose. The method for integrally supporting the coil inner paper tube of the transformer has the advantages that the coil inner paper tube is reliably supported and prevented from moving upwards, repeated operation work caused by the upward movement of the paper tube can be reduced effectively, product quality is ensured, working efficiency is improved, the tool is convenient to disassemble and can be adjusted at will in the length direction, and operation is easy, convenient and reliable.

Description

technical field [0001] The invention relates to a method for supporting a paper tube in an integral coil of a transformer, which is suitable for supporting operations in the process of fitting the paper tube in the integral coil of a transformer, a reactor, and a transformer, and belongs to the technical field of transformers. Background technique [0002] At present, some transformer coils adopt a structure with a hard paper tube inside. During the coil packaging process, it is necessary to ensure that the coil package is tight. During this process, the inner paper tube of the coil is likely to jump up, requiring repeated operations, and affecting product quality. Contents of the invention [0003] The purpose of the present invention is to provide a method for supporting the paper tube in the integral coil of a transformer, which can reliably support the paper tube in the coil, avoid the upward movement of the paper cylinder, effectively reduce the repeated operation work...
