Convenience-for-transportation disorganized transportation transformer and transport case thereof

Abstract

The invention relates to a transportation-friendly disintegrating transportation transformer and a transport case, belonging to the transformer technical field, which comprises single frame double column iron cores, an upper oil tank, a lower oil tank, a coil, an upper integral iron core product clamp and a lower integral iron core product clamp; wherein, two layers of insulation paperboards are arranged between two adjacent single frame double column iron cores and are fixed by adhesive tapes; the coil is arranged on the adjacent single frame double column iron core; a steel washer is arranged between the lower integral product clamps of two adjacent single frame double column iron cores; the upper integral iron core product clamp is arranged above the assembled single frame double column iron core and is fixed with the assembled integral iron core; the upper oil tank and the lower oil tank are combined and then arranged on one end of the iron core. The invention has the advantages that the transportation weight of a single part of the transformer is reduced to 30 tons or below due to disintegrating transportation of the transformer, so the overall transportation weight of the transformer is also reduced; meanwhile, the transformer can bear transportation acceleration during transportation, thereby avoiding deformation and ensuring good performance after reaching the site; the transformer, the transportation clamps of the iron cores and the integral product clamps are all convenient to assembly to meet the on-site assembly requirements.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a disassembled transportation transformer and a transportation box thereof which are convenient for transportation. It is suitable for single-phase or three-phase disintegrated transport transformers with voltage above 220kV, capacity above 360MVA, and total weight between 200 and 400 tons. Background technique [0002] With the rapid development of my country's economic construction, the transformers required for power generation and transmission are developing in the direction of high voltage and large capacity, and the weight of the products often exceeds 200 tons. In the poor mountains and rivers, when the total weight of the transformer required for the project exceeds the carrying capacity of the road, it will limit the smooth construction of the project. There are mainly the following defects: [0003] 1. Traditionally, under extremely harsh natural conditions, the t...

AI Technical Summary

Problems solved by technology

[0003] 1. Traditionally, under extremely harsh natural conditions, the transportation of high-voltage and large-capacity transformers requires mountain-building and road construction, and the project construction funds are huge;

[0004] 2. Engineering construction, road construction and bridge construction seriously damage the natural environment and do not meet environmental protection requirements;

[0006] 4. The method of splitting the three-phase transformer into three single-phase transformers and combining them on site can basically meet the transportation requirements of the transformer, but when the product transportation weight is limited to 40-60 tons, the above method cannot meet the transportation requirements
