HZ-600H Transformer Winding Deformation Detection Equipment

System Introduction

Transformer winding deformation tester is used to test the deformation of 66kV and above voltage level power transformers and other special-purpose transformer windings. Power transformers will inevitably be impacted by various fault short-circuit currents or physical impacts during operation or transportation. Under the action of strong electrodynamic forces generated by short-circuit currents, transformer windings may lose stability, resulting in local distortion, bulging or displacement Such as permanent deformation phenomenon, which will seriously affect the safe operation of the transformer. This instrument uses the frequency response analysis method to measure the winding deformation of the transformer according to the national electric power industry standard DL/T911-2016 and the international electrical standard IEC60076-18. It detects the amplitude-frequency response characteristics of each winding of the transformer and conducts longitudinal or horizontal analysis of the detection results. By comparison, according to the degree of change in the amplitude-frequency response characteristics, the possible deformation of the transformer winding can be judged.

The system consists of a measurement part and an analysis software part, the analysis part is completed by a laptop, and the measurement part is connected to the laptop through a USB cable.
