Description

Technical Field

[0001] The invention relates to the field of online monitoring, in particular to a rapid monitoring device for dissolved acetylene in oil. Background Art

[0002] During the normal operation of the transformer, transformer oil and fiber insulation materials will slowly age and decompose under the influence of moisture, oxygen, heat, and the catalytic effects of materials such as copper and iron. The small amount of acetylene gas produced will mostly dissolve in the oil. The acetylene content in the transformer oil is related to the normal use of the transformer, so it is necessary to regularly detect the acetylene gas in the transformer oil. The invention of the existing publication number CN115235855B discloses a degassing device, a degassing method and a gas detection system in transformer oil. The degassing device includes a degassing container, a gas source storage module, a collecting container and a gas source driving element. It points out that the transformer oil is degassed and separated online by the source driving element of the degassing device to obtain the gas to be detected. Since the online detection needs to rely on the detection unit for chromatographic detection, the shortest conventional monitoring cycle in the power industry is 1 hour. When the transformer fails and the acetylene content in the oil increases significantly, the monitoring may be delayed, which brings certain hidden dangers to the safe use of the transformer. In addition, during the monitoring process, when the acetylene gas content in the transformer oil is low, the separation effect and efficiency are relatively low during the oil-gas oscillation separation, thereby affecting the analysis and judgment of key data.
