Abstract

The invention provides an oscillatory wave partial discharge data conversion method and a related device and belongs to the technical field of data conversion. The method comprises the following steps of firstly, judging whether testers of other models are replaced or not, if so, entering a data correction process, adjusting a wavelet denoising parameter and a discharge amplitude correction parameter by using standard oscillation wave partial discharge data, then denoising and correcting the input oscillation wave partial discharge data to be converted by using the two parameters, and finally, converting to obtain partial discharge data with a unified format standard. According to the method, a problem that oscillation wave partial discharge measurement data of different oscillation wave partial discharge detectors cannot be de-noised and analyzed uniformly is solved.

Description

technical field [0001] The invention belongs to the technical field of data conversion, and in particular relates to an oscillatory wave partial discharge data conversion method and a related device. Background technique [0002] Partial discharge mainly refers to the non-penetrating discharge phenomenon of the electrodes of the insulating medium of high-voltage equipment under the action of high electric field strength, which leads to certain safety hazards and accelerates the aging of the insulating layer. With the help of the oscillating partial discharge tester, various types of partial discharges in the high-voltage equipment can be quickly found out without stopping the operation of the high-voltage equipment, and on this basis, targeted safety measures can be taken to avoid damage caused by A series of equipment accidents caused by partial discharge will ensure the long-term stable operation of high-voltage equipment. [0003] Oscillatory wave detection technology ha...
