Abstract

The invention discloses a transformer core pressure resistant test fixture which comprises a base and a placing board. The transformer core pressure resistant test fixture is characterized by further comprising a horizontal test assembly and a vertical test assembly. The horizontal test assembly comprises a front probe unit, a rear probe unit and a horizontal actuating mechanism used for driving the front probe unit and the rear probe unit to be close to each other. The vertical test assembly comprises an upper probe unit and a vertical actuating mechanism used for driving the upper probe unit to be close to the placing board. The transformer core pressure resistant test fixture has the advantages of being capable of testing pressure resistant performance of multiple transformer cores at a time, simple in structure, convenient to operate and capable of avoiding errors of manual tests and improving test accuracy.

Description

technical field [0001] The invention relates to a testing jig for a transformer magnetic core, in particular to a testing jig for withstand voltage of a transformer magnetic core. Background technique [0002] After the production of the transformer magnetic core is completed, the manufacturer needs to conduct self-inspection on all aspects of the performance of the transformer, and the quality supervision department also needs to inspect the product, and only those that pass the inspection can enter the market. [0003] In the prior art, for the detection of the withstand voltage performance of the transformer magnetic core, it is necessary to manually hold the voltage rod and make contact measurements on each pin of the transformer one by one. Inaccurate. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a testing fixture capable of testing the withstand voltage performance of multip...
