Abstract

The invention provides a transformer state analysis method based on oil chromatography, and a terminal device. The method comprises the steps of: sampling oil in a transformer at preset time intervals, and performing chromatographic analysis on sampling results to obtain content information of a preset characteristic gas; calculating an absolute gas production rate of the preset characteristic gaswithin a preset time period according to the content information of the preset characteristic gas; and judging whether the transformer is faulty according to at least one of the content information of the preset characteristic gas and / or the absolute gas production rate of the preset characteristic gas within the preset time period. According to the transformer state analysis method provided by the invention, online monitoring is performed on the oil chromatography of the transformer to perform intelligent analysis on the state of the transformer in real time, thereby improving the efficiencyof fault analysis of the transformer.

Description

technical field [0001] The invention belongs to the technical field of electric power detection, and in particular relates to a transformer state analysis method and terminal equipment based on oil chromatography. Background technique [0002] Transformer is one of the more important electrical equipment in the power system, which directly affects the safe operation level of the system. Once an accident occurs, it will cause huge direct and indirect losses. Large-scale power transformers are generally oil-immersed transformers, which are usually composed of cores, primary windings, secondary windings, oil tanks, high and low voltage insulating bushings, etc. The complex structure affects the reliability of transformer operation. Transformer faults can be divided into internal faults and external faults according to the transformer body. The faults in the transformer oil tank are called internal faults. The damage caused by the internal faults of the transformer is much great...
