Withstand voltage test device and withstand voltage test method of transformers

Abstract

The invention relates to the technical field of transformer testing, in particular to a withstand voltage testing device and a withstand voltage testing method of transformers. The withstand voltage testing device comprises a testing unit, a plurality of conveying units arranged at intervals in the front-back direction and a control unit, wherein the test unit is provided with a plurality of teststations; the control unit is respectively connected with the plurality of conveying units, and the control unit controls the conveying units to convey transformers to be tested to the corresponding test stations for voltage withstanding test or output the tested transformers, and accumulates the test time of the transformers. The plurality of transformers can be placed on the plurality of conveying units, and the control unit controls the conveying units to operate to the test stations of the test units to carry out voltage withstanding tests and can monitor the test time of the transformerson each conveying unit; and when the testing time reaches a preset value, the conveying units are controlled to output the transformers, withstand voltage testing can be conducted on a plurality of the transformers at a time, and the testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of transformer testing, in particular to a transformer withstand voltage test device and a withstand voltage test method. Background technique [0002] The transformer withstand voltage test (externally applied high voltage test) is mainly to check whether the main insulation of the transformer is qualified, that is, the insulation condition between the primary coil and the secondary coil, between them and the iron core and the shell. If it is unqualified, it will not only endanger the transformer itself and other connected electrical devices, but also cause danger to the equipment and personnel using electricity. [0003] In the transformer withstand voltage test in the prior art, the testing machine can only test one transformer at a time. Generally, it takes 3 minutes to test the transformer, and the test time is relatively long. On the one hand, it leads to low transformer testing efficiency, which is n...
