Embodiment Construction

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] Before the on-site assembly method of the disassembled UHV AC transformer of the present invention, it is first necessary to determine the design of the construction plant.

[0027] The disassembled UHV AC transformer assembly plant of the present invention divides the plant into areas according to the number and weight of the components of the transformer, and places specific components of the transformer in a specific area, thereby greatly reducing the cost of the ground of the plant; During the assembly process, determine the equipment requirements of each process, and select the appropriate power supply according to the power supply of the equipment, so as to standardize the configuration of the power equipmen...

Abstract

The invention relates to a field assembly method for a split extrahigh-voltage alternating-current transformer. The method includes the steps of lower-segment oil tank packaging, iron core splicing, coil sleeving, upper iron yoke insert and upper clamp installation, lead assembly, semi-finished product testing, upper-segment oil tank installation, transformer body drying, vacuum oil injection, cover hoisting for checking, general assembly, hot-oil circulation and the like. The field assembly method special for the split extrahigh-voltage transformer is proposed on the basis of an existing split transformer assembly plant in combination with the characteristics of the large-capacity extrahigh-voltage alternating-current transformer, and the method can meet various technological requirements of assembly of the split extrahigh-voltage transformer and is beneficial to standardized construction of the split extrahigh-voltage transformer field assembly plant.

Description

technical field [0001] The invention relates to the field of power equipment assembly, and more specifically, relates to a field assembly method of a disassembled ultra-high voltage AC transformer. Background technique [0002] The disassembled UHV AC transformer adopts a modular assembly design process, which can be disassembled and transported, thereby effectively reducing transportation risks and costs, and solving the construction problems of UHV substations in remote mountainous areas with transportation heights and bridge load bearings, etc., and significantly improving The economy of UHV substation has broad application prospects. [0003] The research on disassembled UHV AC transformer is a cutting-edge technology. At present, field assembly and application of disassembled UHV AC transformer has not been realized. With the development of pilot applications of disassembled UHV AC transformers, it is urgent to solve the problems of on-site assembly technology of UHV l...
