Abstract
The invention relates to an accuracy testing method for an oil chromatogram online monitoring device. The method comprises the following steps of: (A), vacuum-pumping a testing system, and filling purified transformer oil which is dehydrated and degassed into the testing system until a proper oil level is reached; (B), connecting an in-and-out oil pipe of an online monitoring device for the oil chromatogram to be tested and the testing system in a sealed mode; (C), starting a heating device and an oil circulating pump to heat the testing oil; (D), adjusting the online monitoring device for the oil chromatogram to be tested in a good working state; (E), adding high-concentration mixed standard gases into the testing system in sequence, gradually increasing the content of components in the oil from low concentration, after the oil sample in the testing system is uniform, starting sampling, performing the offline and online comparison test, and simultaneously performing the offline test by using a laboratory gas chromatograph; and (F), by the offline and online comparison test, testing the accuracy of the oil chromatogram online monitoring device. The method has the advantages that testing accuracy is high, the accuracy of the oil chromatogram online monitoring device is improved, the cost is low, and the like.
