Transformer vibration test system and transformer vibration test method

Abstract

The invention discloses a transformer vibration test system and a transformer vibration test method, and relates to the technical field of power equipment. The technical problem that the vibration of a transformer cannot be tested in the moving process of the transformer is solved. The transformer vibration test system comprises a sensor unit used for measuring vibration data of a transformer, and an acquisition unit used for automatically acquiring and processing the vibration data measured by the sensor unit. The sensor unit is installed on a transformer. The input end of the acquisition unit is connected with the data output end of the sensor unit. The power interface of the acquisition unit is connected with an attachment unit used for supplying power to the acquisition unit. The transformer vibration test system of the invention is applied to vibration test in the moving process of transformers.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a transformer vibration testing system and method. Background technique [0002] The transformer is the core electrical equipment in the substation. For the UHV substation, the transformer is huge in scale and can weigh up to 300 tons to 500 tons. Due to the limitation of the lifting capacity of the crane, the movement of the transformer in the substation cannot be completed by hoisting the crane. [0003] There are two ways to move the existing transformer into place. The first is to remove the bushing of the transformer, release the transformer oil in the transformer box to reduce the weight, and then use jacks and temporary rails to move the transformer into place; the second The second is to move the fully assembled transformer into place, that is, use a special track and a rail transfer car, and move the transformer to the special transfer car through a jack without ...

Problems solved by technology

[0004] However, when using the second method of moving the transformer into place, since the transformer is fully assembled and the bushings and other components are not removed, the vibration during the moving process will have an impact on the safety of the transformer. Especially sensitive parts, the unfavorable vibration during the moving process may cause structural damage to the transformer bushing or affect the function of the transformer bushing during operation. Moreover, the transformer bushing is expensive, and replacing the failed bushing will also cause serious damage. huge economic loss
