Abstract

The invention relates to the technical field of mutual inductor testing, in particular to dry-type current transformer testing equipment and method, and the testing equipment comprises a testing frame which is of a U-shaped structure, and further comprises a placement table which is arranged at the rear side of the testing frame and is used for placing a dry-type mutual inductor; the lifting mechanism is arranged on the testing frame, is positioned below the frame plate surface and is used for lifting the dry-type mutual inductor on the placing table to the frame plate surface of the testing frame for testing; and the testing mechanism is arranged on the rack plate surfaces at the left side and the right side of the testing rack and is used for testing the dry-type mutual inductor lifted to the rack plate surfaces of the testing rack and displaying a testing result. The problem of existing manual carrying is solved; the problems that in the prior art, manual testing is needed one by one, so that the workload is large, the testing effect is low, and the testing result accuracy is not high are solved.

Description

technical field [0001] The invention relates to the technical field of transformer testing, in particular to a dry-type current transformer testing device and method. Background technique [0002] Transformer is a device that can change high voltage into low voltage and large current into small current for measurement or protection systems. According to the insulation medium, it is divided into two types: dry transformer and oil-immersed transformer. Among them, for the dry-type transformer, in order to ensure the stability and safety of the transformer's work, the dry-type transformer needs to be tested in the production process. The current test process is generally to manually move the dry-type transformers to the test platform. Two people: one person holds the test tool to test the dry-type transformers one by one, and the other person records the results, which has a large workload and low test effect. , The accuracy of the test results is not high.
