Description
technical field [0001] The invention belongs to the field of transformer oil detection equipment, in particular to an error calibration device for transformer oil gas analysis. Background technique [0002] Transformer oil is a fractionation product of petroleum, which has the functions of insulation, heat dissipation and arc suppression in transformer applications. The transformer oil after long-term use needs to be tested regularly to avoid deterioration of the oil and cause the effect to decline. At present, spectrometers are used to detect transformer oil. There are insoluble sludge, fibers and dirt in the transformer oil that has been used for a long time. These substances may cause the spectrometer to block and cause a failure. When a spectrometer is used for detection, it is easy to cause errors due to operation and other conditions, which will affect the detection results. Contents of the invention [0003] In order to solve the above problems, the object of the...
