The embodiment of the present application provides a transformer testing device and a testing method. The testing device includes: a high-voltage generating unit connected to the input end of the transformer so that the transformer can generate the required high voltage; a high-voltage testing unit connected to the The output terminal of the transformer is connected to measure the high-voltage signal actually generated by the transformer; the processing module is connected to the high-voltage test unit to receive the high-voltage signal transmitted by the high-voltage test unit and perform data processing to judge whether the transformer is qualified. The transformer testing device of the embodiment of the present application excites the transformer to make the transformer work to generate high voltage, so as to test the high voltage generated during the actual operation of the transformer, and judge whether the transformer is qualified according to the measured high voltage value, thereby improving the accuracy of the detection result Rate.
Description
technical field [0001] The present application relates to the technical field of transformer detection, in particular to a transformer testing device and testing method. Background technique [0002] Transformers need to withstand extremely high voltages during actual use. Existing transformer withstand voltage tester outputs high voltage through the tester, and applies AC high voltage or DC high voltage between the primary pins of the transformer, between the secondary pins, and between the primary and secondary pins, so as to The transformer is tested for withstand voltage. Contents of the invention [0003] In view of this, the embodiment of the present application proposes a transformer testing device and testing method to solve the following problems in the prior art: in the transformer test, because the transformer itself does not work, it is impossible to simulate and detect The high voltage generated when the transformer is working. [0004] On the one hand, the...
