Problems solved by technology

However, because this method is limited to the scope of threshold diagnosis, it is often necessary to diagnose the result when the content of some characteristic gases exceeds the threshold, so that it is difficult to diagnose the fault type in the early stage of the fault.

Abstract

The invention relates to the technical field of transformers, and provides a transformer fault diagnosis method and device. The method comprises the steps: obtaining the current DGA data of a target transformer and the current operation data of the target transformer; inputting the current DGA data and the current operation data into a trained fault diagnosis model to obtain a transformer fault type output by the trained fault diagnosis model, wherein the trained fault diagnosis model is obtained by learning pre-collected historical fault data by adopting a deep learning technology. Accordingto the method disclosed in the technical scheme provided by the invention, the fault type of the transformer can be quickly and accurately diagnosed.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer fault diagnosis method and a transformer fault diagnosis device. Background technique [0002] The transformer is the core equipment of the power system, and it is very important in the production, transmission and consumption of electric power. The research on the fault diagnosis method of the power transformer is of decisive significance to improve the safety and reliability of the power system operation. [0003] Transformer faults can generally be divided into overheating faults and discharge faults. Mechanical faults and internal water and damp faults will develop into electrical faults. Transformer fault types are usually divided into low-energy discharge, high-energy discharge, partial discharge, low-temperature overheating (when the temperature is less than 300°C), medium-temperature overheating (when the temperature is between 300°C and 700°C), and hig...
