Description

technical field [0001] The invention relates to a degassing device specially used for a novel transformer oil chromatographic on-line monitoring device, and belongs to the technical field of automatic monitoring equipment. Background technique [0002] Transformer oil chromatographic analyzer is a device that uses gas chromatography to determine the content of dissolved gas components in insulating oil. It is an oil-filled power equipment for power generation and power supply companies to judge the operation. It is used to monitor whether there are latent overheating, discharge and other faults. It is an effective means to ensure the safe and effective operation of the power grid, and it is also a necessary means for oil-filled electrical equipment manufacturers to conduct factory inspections of their equipment. [0003] The transformer oil chromatographic analyzer needs to be equipped with a degassing device for oil-gas separation, and the accuracy and sensitivity of oil-ga...

AI Technical Summary

Problems solved by technology

[0003] The transformer oil chromatographic analyzer needs to be equipped with a degassing device for oil-gas separation, and the accuracy and sensitivity of oil-gas separation will directly determine the accuracy of on-line monitoring. There are three degassing methods: membrane permeation, headspace degassing and vacuum degassing In terms of vacuum degassing, it not only has high efficiency and good oil-gas separation effect, but it requires high vacuum degree of the system, which leads to defects in the sensitivity and stability of the degassing effect.
