Power transformer with auxiliary maintenance function and maintenance method thereof

Abstract

The invention discloses a power transformer with an auxiliary maintenance function and a maintenance method thereof. The power transformer comprises a transformer body, a bearing plate and a flaw detection assembly; a base is arranged below the transformer body, a lead screw base and a second motor are arranged above the transformer body, and the output end of the second motor penetrates through the lead screw base to be rotationally connected with a second lead screw. The invention specifically relates to the technical field of power transformer maintenance. According to the power transformer with the auxiliary maintenance function and the maintenance method of the power transformer, due to the fact that the movable flaw detection assembly is arranged, cracks in the transformer can be detected through the ultrasonic flaw detector, so that the problems that a coil module and the like in the transformer generate cracks to affect the transformation effect of the power transformer and even damage the transformer due to the fact that charges break down the power transformer are solved. Meanwhile, high-strength current and high potential difference can be shielded through the Faraday cage, so the problem that the ultrasonic flaw detector fails due to interference caused by electricity-to-magnetism is solved.

Description

technical field [0001] The invention belongs to the technical field of power transformer maintenance, and in particular relates to a power transformer with an auxiliary maintenance function and a maintenance method thereof. Background technique [0002] A transformer is a static electrical device used to convert AC voltage and current to transmit AC power. It is based on the principle of electromagnetic induction to achieve electrical energy transfer. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers in terms of their uses: power transformers are necessary equipment for power transmission and distribution, and power user distribution; test transformers can withstand voltage (boost) for electrical equipment Test equipment; instrument transformers are used for electrical measurement and relay protection of power distribution systems (PT, CT); special-purpose transformers include electric furnace tr...

AI Technical Summary

Problems solved by technology

[0003] Existing power transformers are generally only inspected for electrical connection lines, coil modules, and input and output voltages of the power transformer during maintenance, and lack crack detection operations for power transformer components. Cracks will affect the voltage transformation effect of the power transformer, and even cause the charge to break down the power transformer and cause the transformer to be damaged.
