The invention discloses a configuration device and method of standard oil for online monitoring and verification of transformer oil chromatography, the size of the internal volume of an oil cylinder is adjusted through the movement of a piston, an oil pump pumps oil into an oil distribution cylinder, and a circulating pump circulates the oil from the bottom to the upper part and sprays the oil in the form of oil mist, so that dissolved gas in the oil is convenient to separate; the vacuum pump pumps out original gas in oil for oil filtering, the standard gas bottle is opened, and standard gas needing to be added is sucked in through a certain vacuum degree in the oil distribution cylinder. The circulating pump enables oil to circulate in the cylinder to be fused with gas, and the oil distribution process can be completed after standing for a period of time. The device has the innovation points that the device can be connected with oil sample detection equipment to detect prepared oil, and if a detection result is unqualified, gas can be automatically refilled until the requirement is met. Therefore, oil distribution can be achieved, and the functions of oil sample detection, oil chromatography detection and the like are achieved.
Description
technical field [0001] The invention belongs to the technical field of power equipment monitoring, and in particular relates to a standard oil configuration device and method for on-line monitoring and verification of transformer oil chromatography. Background technique [0002] Transformer is one of the most important equipment in power system. Early detection of transformer latent fault or detection of fault type and severity is very important for safe and reliable operation of the entire power system, reducing fault repair time and reducing economic losses. There are many methods for fault diagnosis and operation status evaluation of power transformers, among which the analysis of gas composition and concentration in transformer oil is one of the most important basis for judging transformer faults. The "Preventive Test Regulations for Electric Power Equipment" lists the detection method of dissolved gas in oil as the first transformer condition monitoring technology. Whe...
