Transformer insulation state testing equipment, method and device and storage medium

Abstract

The invention relates to transformer insulation state testing equipment, method and device and a storage medium. The insulation state testing equipment of the transformer comprises a controller, a data acquisition device and a stress applying device used for applying stress to a to-be-tested oil paper insulation test sample. The data acquisition device comprises a temperature detection device used for collecting the winding temperature of a to-be-tested transformer, a vibration measurement device used for collecting vibration data of the to-be-tested transformer, and a voltage acquisition device used for collecting the operation voltage of the to-be-tested transformer. The controller obtains temperature data transmitted by the temperature detection device, vibration data transmitted by the vibration measurement device and voltage data transmitted by the voltage acquisition device, and instructs the stress applying device to apply corresponding stress to the to-be-tested oil-paper insulation test sample according to the temperature data, the vibration data and the voltage data. Through the insulation state testing equipment of the transformer, the insulation state of the transformer can be obtained in a lossless mode, and the normal operation of the transformer can be kept.

Description

technical field [0001] The present application relates to the technical field of transformer detection, in particular to a transformer insulation state testing equipment, method, device and storage medium. Background technique [0002] The power transformer is the core equipment of the power grid. The design life of the power transformer reaches 40 years, but in actual use, its life is often affected by various factors during operation. Accurate evaluation of the insulation state of power transformers is an important link to ensure the safe operation of transformers. At present, methods for evaluating the insulation state of transformers include various detection methods such as frequency-domain dielectric spectroscopy, dissolved gas analysis in oil, and partial discharge. [0003] During the implementation process, the inventor found at least the following problems in the traditional technology: the traditional testing method has the problems of high testing cost and low te...
