Problems solved by technology
However, for large-scale multi-functional transformers, due to their complex electrical properties, there are too many index data to be detected, and manual detection is extremely error-prone.
In addition, there are many types of instruments involved in performance testing, and the workload of testing is heavy. A little carelessness may damage the instruments or even cause safety accidents.

According to the detection device, the multiple performance indexes of the transformer can be automatically detected.
Description
technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a transformer performance detection device. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components include primary coil, secondary coil and iron core (magnetic core), which are mainly used for voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. Before the transformer leaves the factory or is used, it needs to be tested for various performance indicators. In the prior art, most of the accurate values are obtained by directly contacting the instrument probe with the transformer. But for large-scale multi-functional transformers, due to their complex electrical properties, there are too many index data to be detected, and manual detection is extremely error-prone. In addition, there are many types of instruments involved ...
