Device for detecting dissolved gas in insulating oil of oil-filled electrical equipment

The invention discloses a device for detecting dissolved gas in insulating oil of oil-filled electrical equipment. Accurate and quantitative analysis of the dissolved gas in the insulating oil of the oil-filled electrical equipment is realized through a simple and practical gas path flow. Comprising a sample inlet, a chromatographic column, a thermal conductivity detector (TCD), a hydrogen flame ionization detector (FID) and a six-way valve, the sample inlet is communicated with an inlet of the chromatographic column, an outlet of the chromatographic column is communicated with an inlet of the thermal conductivity detector (TCD), an inlet (6) of the six-way valve is connected to an outlet of the thermal conductivity detector (TCD), a nickel catalyst converter (Ni) is connected to a first outlet (1) of the six-way valve, and a second outlet (2) of the six-way valve is connected to a second outlet (3) of the six-way valve. The output port of the nickel catalyst converter (Ni) is communicated with the input port
