Description

technical field [0001] The present invention relates to the technical field of testing equipment, and more particularly, to a fixture device for transformer testing. Background technique [0002] In the operation of power equipment, transformer DC resistance test is a simple and very important test link in transformer test. By testing the DC resistance of the transformer winding connected to its bushing, it can check the internal wire joints of the winding and the welding quality of the leads and the winding joints. Whether the connection of the parallel branch is correct, and at the same time, it can also check whether the current-carrying part of the transformer is open or not, the contact is poor, and the winding is open. However, in the prior art, most of the clamps used for detection are wire clamps composed of left and right half clamps. When clamping the cable head, there is a problem of poor clamping stability. SUMMARY OF THE INVENTION [0003] The purpose of the...
