Abstract

A method for calculating the area of chromatographic peaks of a gas in electric power equipment oil relates to the technical field of electric power equipment detection, and can solve a technical problem of the increase of the calculating precision. The method comprises the following steps: drawing a chromatographic curve of the gas in transformer oil, calculating the chromatographic starting point value, the cutoff point value and the peak maximum height value according to the beginning and ending time points and the smooth time length of the chromatographic curve, and calculating according to a peak processing function to obtain the chromatographic peak area of the chromatographic curve of the target gas. The method is suitable for detecting the content of the gas in the transformer oil.

Description

technical field [0001] The invention relates to electric equipment detection technology, in particular to a technology for calculating the gas chromatographic peak area in oil of electric equipment. Background technique [0002] In the power system, the insulating material and insulating oil in the oil-filled pipeline of power equipment in normal operation will gradually age under the action of heat, electricity, etc., and produce a variety of flammable gases. These gases in the oil-filled pipeline of power equipment Continuous accumulation, convection, diffusion, and dissolution in the oil until it is saturated and bubbles are precipitated. Analysis of the gas content in the power equipment oil can identify the insulation status of the power equipment and the discharge of the internal electrical equipment, which can effectively reduce power equipment accidents happened. [0003] One of the detection methods of gas content in power equipment oil is to use chromatograms. The...
