Description

technical field [0001] The invention relates to a novel transformer oil chromatography on-line monitoring device, which 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 accuracy and sensitivity of oil-gas separation of transformer oil chromatographic analyzer will directly determine the accuracy of online monitoring. Regarding the three degassing methods o...
