Iron core transporting method and iron core transporting device for field-assembled transformer

Abstract

The invention provides an iron core transporting method and an iron cover transporting device for a field-assembled transformer. The method comprises the following steps of removing the assembled part of an upper iron yoke, an iron cover upper beam and a coil of an iron core of the field-assembled transformer, wherein the iron core with the assembled part of the upper iron yoke, the iron cover upper beam and the coil removed is an un-disassembled iron core; and putting the un-disassembled iron core into an oil tank at the lower section of a transformer body for transportation. By adopting the method for transporting the iron core, the transportation cost is relatively low, total transportation weight of existing field-assembly transformers in transportation can be reduced, and the procedure of field assembly can be reduced after transportation.

Description

technical field [0001] The invention belongs to the technical field of transformer manufacturing, and relates to an iron core transportation method and an iron core transportation device for on-site assembled transformers. Background technique [0002] In recent years, with the rapid development of my country's power grid construction, more and more ultra-high voltage, ultra-high voltage, and large-capacity transformers are used in the power grid, and the above-mentioned transformers are generally difficult to transport due to their large size and heavy weight. question. Especially for the traditional high-voltage three-phase main transformer, due to its large size and heavy weight, the transportation problem is more serious, especially for remote mountainous areas where transportation conditions are severely restricted. With the continuous development of transformer technology, in order to solve the above transportation problems, field-assembled transformers emerged as the ...

AI Technical Summary

Problems solved by technology

[0004] For this method of dismantling and transporting the iron core of the transformer, since it is necessary to make a plurality of iron core frame transport boxes and boxes for transport clips for transporting the iron core frame, the transportation cost is relatively high, and each iron core frame is transported During the process, it needs to be kept firm and not loose, so the process of transporting the disassembled iron core is complicated, and to a certain extent, the on-site iron core assembly process is increased
