Abstract

The invention discloses transformer detection equipment, and the equipment comprises a variable-frequency power supply which is connected with an integrated measurement and control device, and is used for providing a power supply for integrated measurement and control equipment; and the integrated measurement and control device which is connected with a to-be-detected transformer and is used for outputting a preset voltage signal to the to-be-detected transformer and detecting the to-be-detected transformer according to the operation data of the to-be-detected transformer. The transformer detection equipment disclosed by the invention has the capability of testing transformers with the voltage class of 10 kV to 500 kV; the test capability of a 60Hz product can be carried out while the test capability of a 50Hz transformer is met. The partial discharge test capability is met, and the partial discharge problem of the IGBT power supply is solved; one set of variable frequency power supply can replace the original voltage regulator, power frequency generator set and intermediate frequency generator set equipment; highly integrated measurement is achieved, and errors and uncertainty of a measurement loop are reduced.

Description

technical field [0001] The present invention relates to the technical field of transformer detection, and more specifically, to a transformer detection device. Background technique [0002] The vigorous development of the power industry has led to a sharp increase in the demand for power transmission and transformation equipment, and the requirements for the technical performance of power transmission and transformation equipment are getting higher and higher. Transformers are the basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities, etc. For transformer manufacturers, transformer testing is an important part of controlling and ensuring product quality in the manufacturing process; for testing departments, a complete transformer testing system is one of the important means to supervise the transformer products shipped by the manufacturer, so the test station And equipment investment is a key...
