Problems solved by technology

[0004] The peak time of the chromatographic curve of gases in transformer oil will change with the environmental conditions in the transformer oil-filled pipeline. When the variation of the peak time of the chromatographic curve accumulates to a certain extent, it will affect the identification of component gases with long peak time , causing component gas identification errors and affecting the calculation accuracy of component gas content

Abstract

The invention discloses a peak time calculation method of multicomponent gases in transformer oil, and relates to the technical field of power transformers. The method is used for improving the calculation accuracy of the gas content. The method comprises the steps that: a typical chromatogram of each component gas in the transformer oil is acquired; the peak time of each component gas on the typical chromatogram is recorded; a real-time chromatogram of each component gas is acquired; the peak time of a first component gas and a second component gas on the real-time chromatogram is acquired; and the peak time and an appearance time range of other component gases on the real-time chromatogram are calculated according to the peak time of the first component gas and the second component gas on the real-time chromatogram as well as the peak time of each component gas on the typical chromatogram. The method can effectively avoid component gas identification errors, and can improve the calculation accuracy of the component gas content.

Description

technical field [0001] The invention relates to power transformer technology, in particular to a technology for calculating the peak time of multi-component gas in transformer oil. Background technique [0002] The insulating material in the oil-filled pipeline of a transformer in normal operation will gradually age under the action of heat and electricity, and produce a variety of flammable gases. These gases accumulate, convect, diffuse, and dissolve in the oil in the oil-filled pipeline of the transformer. Bubbles will be precipitated until saturated, the gas in the oil will be precipitated, and the gas content of the gas components will be analyzed to identify the insulation status of the transformer and the discharge of internal electrical equipment, which can effectively reduce the occurrence of transformer accidents. [0003] The identification method of multi-component gas in transformer oil usually adopts the online state detection method. The principle is to separa...
