Full-automatic dielectric oil chromatographic analysis system

Abstract

The invention discloses a full-automatic insulating oil chromatographic analysis system which comprises an automatic desaeration and sample introduction device, an insulating oil chromatographic analysis system and a monitoring platform; wherein, the automatic desaeration and sample introduction device comprises an oil sample pretreating device, a pressurizing sampling device and a transmission pipeline; the insulating oil chromatographic analysis system includes an insulating oil gas chromatograph and an air source; the monitoring platform comprises a signal communication system and a data processing system; the automatic desaeration and sample introduction device is connected with an introduction port of the insulating oil chromatographic analysis system through the transmission pipeline, and the automatic desaeration and sample introduction device and the insulating oil chromatographic analysis system are connected with the monitoring platform by a USB signal wire. The chromatographic analysis system has high degree of automation as well as simple and convenient operation, can automatically finish the process of insulating oil sample desaeration, extraction and sample introduction analysis, and automatically judges the types of the fault of an oil charge electrical device.

Description

technical field [0001] The invention relates to a detection and analysis instrument, in particular to an automatic chromatographic analysis system for monitoring the running state of a power transformer, in particular to a high degree of automation that can automatically process, analyze and monitor collected insulating oil samples Automated chromatographic analysis system for transformer failure types. Background technique [0002] At present, the domestic power system needs to analyze the dissolved gas in the insulating oil when the oil-filled electrical equipment is maintained and tested. The most widely used is laboratory chromatographic analysis, and it is also an arbitration method adopted by the testing department. In the short term, online chromatographic monitoring equipment Difficult to replace laboratory chromatography. Because laboratory chromatographic analysis requires special degassing of the retrieved oil samples, and then performing chromatographic analysis...

Problems solved by technology

[0002] At present, when the domestic power system conducts maintenance and testing on oil-filled electrical equipment, it needs to analyze the dissolved gas in the insulating oil. The most widely used is laboratory chromatography analysis, which is also the arbitration method adopted by the testing department. Difficult to replace laboratory chromatography

Because the laboratory chromatographic analysis needs to carry out special degassing treatment on the retrieved oil samples, and then carry out chromatographic analysis through manual gas extraction, the whole process has many steps, complicated operation, high requirements for operators, and many error factors. The accuracy of chromatographic analysis has a great influence, thus affecting the accurate judgment of oil-filled electrical equipment failure
