A kind of power transformer operation and maintenance method

Abstract

The invention relates to a power transformer operation and maintenance method, which uses a surface cleaning device. The surface cleaning device includes a frame, a handrail, a mounting rod and a cleaning device. The handrail is installed on the side wall of the frame, and the upper end of the frame is installed with a The installation rod is installed with a cleaning device between the installation rod and the frame; the specific methods of using the above surface cleaning equipment to maintain the box-type transformer are as follows: circuit disconnection, shell cleaning, accessories cleaning, accessories replacement and circuit connection. The surface cleaning equipment provided by the present invention can cooperate with the manual cleaning method to complete the cleaning of the box-type transformer casing, reducing the workload of the staff. The cleaning device is provided with a No. 1 cleaning mechanism adapted to the casing structure and The No. 2 cleaning mechanism can effectively clean the top surface of the casing and the protrusions, avoid the occurrence of cleaning dead corners, and improve the overall cleaning effect.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method for operation and maintenance of a power transformer. Background technique [0002] The box-type transformer concentrates the traditional transformer in the box-type housing. Because the box-type transformer has many advantages such as small footprint, convenient operation, high application benefits, flexible combination, and high operating safety, it is widely used in various fields. Among them, it has become an indispensable and important power equipment in today's power engineering construction. [0003] In order to ensure the normal operation of the box-type transformer, it needs to be maintained regularly, including the cleaning of the box-type transformer shell. At present, there are some problems in the process of cleaning the box-type transformer shell: [0004] (1) Due to the large overall size of the box-type transformer, it takes a lot of time and physical stren...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the large overall volume of the box-type transformer, it takes a lot of time and physical strength to clean the surface of the shell only by manual methods, and the labor intensity of the staff is relatively high. Working for a long time or the overall cleaning speed gradually slows down, and then lead to low work efficiency

[0005] (2) The top surface of most box-type transformer shells has a pointed structure, and the upper side wall is provided with eave-like protrusions. When the surface of the box-type transformer is cleaned manually, the top surface and protrusions of the box-type transformer shell are usually not available. Effective cleaning, so the cleaning is not thorough, and the residual dust and other stains not only reduce the aesthetics of the shell surface, but may also affect the normal operation of the components installed on the box-type transformer shell
