The invention discloses a main transformer oil chromatography on-line monitoring system. The system comprises a box body, an oil suction pipe, an oil pump, an oil-gas separator, a check valve and a backflow pipe, wherein one end of the oil suction pipe is arranged in the middle of the bottom end of the right side of the box body; the oil pump is mounted on the right side of the bottom of the inner cavity of the box; the oil-gas separator is mounted at the upper right corner of the rear side of the inner cavity of the box body; the check valve is fixedly mounted on the left side of the oil-gas separator; and the backflow pipe is arranged at the bottom end of the right side of the box body and located on the rear side of the oil suction pipe. The main transformer oil chromatography on-line monitoring system can extract fault gas from a collected sample at any time for analysis, realizes real-time operation state monitoring of the transformer, can timely discover potential faults in the operation process of the power transformer, forms a perfect and reliable analysis report, and the mounting frame can be stably moved out of the box body from the inner cavity of the box body, and the height of the mounting frame is reduced in the moving process, so that an operator can conveniently maintain or replace the gas storage tank regularly, and time and labor are saved.
Description
technical field [0001] The invention relates to the technical field of oil chromatography monitoring, in particular to an online monitoring system for main transformer oil chromatography. Background technique [0002] Oil chromatography on-line monitoring system is a precision equipment integrating control, measurement and analysis technology. It can monitor oil-immersed high-voltage equipment such as power transformers, electric arc furnace transformers, reactors, and transformers with a voltage level of 110kV and above. Accurately detect the concentration and change trend of various fault characteristic gases dissolved in insulating oil. According to the national standard "GB / T 7252-2001 Dissolved Gas Analysis and Judgment Guidelines in Transformer Oil", the oil chromatography online monitoring system must be able to analyze the To judge the internal fault gas of electrical equipment, among them, the fiber is overheated and decomposed to produce carbon monoxide, carbon dio...
