Multi-frequency-multiplication induction voltage withstanding device for voltage transformer frequency multiplication induction voltage withstanding test

Abstract

The invention discloses a multi-frequency-multiplication induction voltage withstand device for a voltage transformer frequency multiplication induction voltage withstand test, a transposition mechanism comprises a connecting box, the outer surface of the connecting box is movably connected with the inner surface of a connecting groove, the outer surface of the connecting box is fixedly connected with the outer surface of a connecting plate, and the invention relates to the technical field of voltage withstand tests. According to the multi-frequency-multiplication induction voltage withstand device for the voltage transformer frequency multiplication induction voltage withstand test, the transposition mechanism is arranged, the connecting thread sleeve rotates so as to be in threaded connection with the connecting stud, and the connecting thread sleeve is electrically connected with the access end of the multi-frequency-multiplication induction voltage withstand test device, so that the test structure is more accurate, and the test efficiency is improved. The service life of the access circuit can be prolonged, the situation that the device cannot be used due to damage of the access circuit is avoided, and through the combination of the structures, the problems that an existing multi-frequency-multiplication induction withstand voltage testing device is only provided with one access end used for being connected with 220V and 380V voltages, the testing result is prone to being affected after long-term use, and the access circuit is damaged are solved.

Description

technical field [0001] The invention relates to the technical field of withstand voltage testing, in particular to a multi-frequency induction withstand voltage device for a voltage transformer frequency-multiplied induction withstand voltage test. Background technique [0002] The multi-frequency induction withstand voltage test device can realize the functions of automatic boosting, automatic timing after boosting to the set value, and automatic voltage reduction after timing. The operation is extremely simple, integrated structure, light weight, and easy to carry. [0003] The existing multi-frequency induction withstand voltage test device has only one power input terminal, and can be used to connect 220V or 380V wiring voltage. Because the difference between the two voltages is large and they share one access circuit, it not only affects the withstand voltage test The test structure of the device, and long-term use is likely to cause damage to the access circuit, so it ...
