Transformer winding deformation on-line monitoring method based on on-line frequency response method

The invention provides a transformer winding deformation on-line monitoring method based on an on-line frequency response method. The transformer winding deformation on-line monitoring method comprises the steps that a swept-frequency signal is generated and is loaded to a transformer winding through a power amplifier; a data acquiring module acquires a low-voltage signal filtered through a second filter and converts the low-voltage signal to a digital signal; a data processing module converts the digital signal to a frequency response, calculates coefficients related to distinguishing of transformer winding deformation according to the input digital signal and judges the degree of the transformer winding deformation. The transformer winding deformation is analyzed based on the frequency response method so that the deformation degree of the transformer winding can be monitored on line, and the accidents caused by the transformer winding deformation can be prevented in time. Due to the fact that the frequency of an interference signal is not located in the range of frequency scanning points, electromagnetic interference is effectively reduced. A frequency spectrum signal is directly output and displayed, a frequency-response curve can be analyzed visually, and the deformation degree of the transformer winding can be judged.
