Transformer Oil Chromatography-line Monitoring Device To Establish Network Testing Platform

It’s particularly important to monitor the working condition of Power Transformer, which is one of the most important power system equipment. Oil-immersed transformer is the most widely used one, when the internal failure insulating oil and paper will break down a variety of gases dissolved in transformer oil mainly. Transformer oil chromatography-line monitoring device uses this principle to early fault diagnosis of transformer operation.However, through the remote maintenance to the oil chromatography-line monitoring device which has been installed, find that the state apparatus can not work monitoring and reporting effectively to the Important large transformer. Therefore, in order to enable on-line monitoring device to better serve us, decide to test the on-line monitoring before it join the network, the purpose is keeping the quality of the on-line monitoring device has been strictly controlled, reduce the probability of failure after installation.According to the State Grid Corporation of corporate standards "substation equipment on-line monitoring device testing norms", After the comparison and analysis with the traditional methods of domestic oil chromatography-line monitoring device. In order to determine the accuracy of the device, this article design a standard oil sample preparation device, which is also called calibrator, to simulate the running transformer oil, by comparing the results of this analysis of oil samples and oil sample standard value with which device to be tested. And according to this idea, based on the Offline existing laboratory chromatography detector, established Network testing platform of Line monitoring devices.The main portion of the platform also includes laboratory chromatographic detection systems and communications test systems. Wherein the platform Calibrator is important equipment and innovation. The Calibrator design ideas, design principles and workflow is described importantly in this paper, then the accuracy of the device is verified.At last, after the building of oil chromatographic network testing platform, take measures of standardized testing to the equipment which is about to access substation and comes from different manufacturers, and track the equipment which is qualified. Compared with the equipment which has been tested and the one which has not been tested showed that the accuracy of the device and the failure rate of the device reduced significantly.
