Method, device, equipment and medium for measuring content of functional groups in transformer oil sample

Abstract

The invention discloses a method, a device and equipment for measuring the content of functional groups in a transformer oil sample and a medium. The content measurement method comprises the following steps: acquiring an infrared absorption spectrum of a transformer oil sample functional group and a background infrared absorption spectrum of a transformer-free oil sample functional group; determining absorbance corresponding to a preset range wavelength according to the infrared absorption spectrum; determining the wave path length of infrared light of the infrared absorption spectrum according to the background infrared absorption spectrum; and determining the content of the specific luminous energy group of the transformer oil sample according to the absorbance and the wave path length. According to the scheme, the content of the functional group of the transformer oil sample is accurately measured, and the measuring method is simple and reliable.

Description

technical field [0001] The embodiments of the present invention relate to the technology for measuring the content of functional groups in oil and gas, and in particular to a method, device, equipment and medium for measuring the content of functional groups in transformer oil samples. Background technique [0002] The quality of transformer oil in oil-immersed transformers is of great significance to the safe and stable operation of the transformer. However, there are many cases showing that during the handover and acceptance process of the transformer, the insulation test of the transformer oil will fail. After investigation, it is found that the transformer oil is not provided according to the contract requirements, and there are "subsequent" and "fake ones". This phenomenon poses a great hidden danger to the security of the power grid. On the other hand, the case also shows that the insulation resistance of some main transformers has not been up to the standard, and sti...

Problems solved by technology

[0003] However, in the prior art, the quality of transformer oil is often judged and screened by the dissolved gas in the oil, volume resistivity, dielectric loss, copper ion content, etc. This method comprehensively judges the performance of the oil product from the perspective of several physical properties, collect There are many parameters, resulting in a more cumbersome detection process
