An external withstand voltage test equipment for power transformers

Abstract

The invention discloses an externally applied withstand voltage test equipment for a power transformer, which comprises a base plate and a support frame fixedly connected to the upper surface of the base plate, one side of the support frame is connected with a voltage adjustment mechanism for input voltage change, the The other side of the support frame is connected with a collection mechanism corresponding to different input voltages, the voltage adjustment mechanism includes a second installation plate, the second installation plate is fixedly connected to the side wall of the support frame, and the back of the support frame A drive mechanism for intermittently rotating the second installation shaft is connected, and a transmission mechanism is connected between the drive mechanism and the collecting mechanism. The invention can change the size of the incoming current through the change of the length of the resistance ring, and can realize the adjustment of the voltage. At the same time, with the function of the transmission mechanism, the first rotating rod can be further contacted with a single collection block, and different voltage values ​​can be completed. Under the corresponding data collection, thus greatly improving the efficiency of the experiment.

Description

technical field [0001] The invention relates to the technical field of power transformers, in particular to an external voltage withstand test equipment for power transformers. Background technique [0002] A transformer refers to a device that uses the principle of electromagnetic induction to change the AC voltage. It is an extremely important device in power construction and is widely used in today's production and life. It is precisely because of such an important position that the transformer needs to be withstand voltage For testing, the existing external voltage withstand test equipment for power transformers generally needs to collect multiple sets of data by changing the voltage value. In this process, the data collection efficiency is low, it is not convenient for a single collection of corresponding points, and errors are prone to occur. Contents of the invention [0003] The purpose of the present invention is to provide an externally applied withstand voltage ...
