Description

technical field [0001] The invention belongs to the technical field of on-line monitoring of transformer oil chromatography, and in particular relates to a degassing device for on-line monitoring of transformer oil chromatography. Background technique [0002] At this stage, the application of power equipment such as generators, transformers, and motors in my country has tended to be large-scale (ultra-large) and high-voltage. Large-scale power transformers are important substation equipment in power systems, and their operating status directly affects the safety of the system. Real-time or regular online monitoring of the operating status of power transformers is of great significance. [0003] The internal faults of power transformers are mainly manifested in the form of heat and electricity. Whether it is an electrical fault or a thermal fault, gas will be generated in the oil. The composition and content of the gas in the transformer oil can be used as the characteristic...
