The invention discloses an insulating oil plasma chromatograph sample gas passage airtightness on-line detection method, which comprises a gas collecting pipe, an enrichment chamber, a pressurizing member and a sensor, the gas collecting pipe is hermetically sleeved outside the insulating oil plasma chromatograph sample gas passage, two ends of the enrichment chamber are respectively connected with the gas collecting pipe through pipelines, and the pressurizing member is connected with the gas collecting pipe through a pipeline. The pressurizing piece is connected to the gas inlet end of the enrichment chamber, and the sensor is located in the enrichment chamber; the gas collection pipe is communicated with the enrichment chamber during detection, the pressurizing part pressurizes the gas in the gas collection pipe and then the gas enters the enrichment chamber, the sensor detects the pressurized gas, and if the detected sample gas is leaked, the gas collection pipe is communicated with the enrichment chamber
