Transformer core transporting and fixing method

Abstract

The invention discloses a transformer core transporting and fixing method. The transformer core transporting and fixing method involves a box body with an opening at the upper end of the box body, a cover body is installed on the box body, an air inlet is formed in the lower part of the box body, and connecting structures are arranged on the lower bottom of the box body and side walls of the box body; the method further involves an upper clamping piece, a lower iron yoke, a lower clamping piece, a core column and an iron core of a side column, the iron core is fastened into a rigid body through transportation clamping pieces, a positioning pressing beam strides over the lower iron yoke and the lower clamping piece, trapezoidal wood is installed among the positioning pressing beam, the lower iron yoke and the lower clamping piece, the two ends of the positioning pressing beam are fixedly connected with the connecting structures of the lower bottom of the box, a fixing bracket is fixedlyconnected with the connecting structure on one side wall of the box body, a group of jacks are arranged on the inner side of an adjustable bracket, an insulating partition plate is arranged between each jack and the transportation clamping pieces, and the jacks are screwed out to abut against the transportation clamping piece and are fastened. According to the transformer core transporting and fixing method, the possibility of long-distance transportation of the iron core part of the transformer is realized, and meanwhile, the iron core can be ensured to be good in fixing effect and not to deform in the transportation process so that the possibility of damage, destruction and the like of the iron core caused by transportation can be greatly reduced.

Description

technical field [0001] The invention relates to a method for transporting and fixing a transformer iron core. Background technique [0002] With the development of DC transmission in China, in order to meet the installation of large-scale converter transformers in remote areas with poor transportation conditions, the iron core is designed to be disassembled, and the iron core can be decomposed into several U-shaped frames, which are respectively loaded into the transportation device transportation. Since there is no upper iron yoke and the core column of the U-shaped iron core frame is semicircular, the silicon steel sheet is likely to be displaced during transportation, and the dimensions such as core diameter and column spacing cannot be guaranteed, resulting in difficulty in coil assembly. Contents of the invention [0003] In order to solve this problem, a transportation and fixing method for the transformer iron core was invented, which can effectively ensure the siz...
