Insulating oil plasma chromatograph sample gas passage airtightness detection device

The utility model discloses an insulating oil plasma chromatograph sample gas path air tightness detection device, which comprises a gas collecting pipe, an enrichment chamber, a pressurizing piece and a sensor, the gas collecting pipe penetrates along the length direction, two ends of the enrichment chamber are respectively connected with the gas collecting pipe through pipelines, the pressurizing piece is connected with the gas inlet end of the enrichment chamber, and the sensor is connected with the gas collecting pipe. And the sensor is positioned in the enrichment chamber. The device has the beneficial effects that a detection gas path and a sample gas path are relatively independent and do not interfere with each other, the problem that the tiny leakage of the insulating oil plasma chromatograph is not detected in place is solved, and the detection accuracy of the insulating oil plasma chromatograph is improved. 本实用新型公开绝缘油等离子色谱仪样气通路气密性的检测装置，包括集气管、富集室、增压件、传感器，所述集气管沿长度方向贯穿，所述富集室的两端分别通过管路连接所述集气管，所述增压件连接在富集
