Analysis and Treatment of Transformer Heating Based on Infrared Thermometric Technology

Abstract

In order to realize the diagnosis and analysis of electrical equipment running state, improving the detection technical level, the infrared thermometric technology has become an important way of state maintenance and evaluation for electrical equipment. As an important equipment in the power gird, the running reliability of transformer are directly affect the accuracy of power grid monitoring data. As for the abnormal heating of transformer, analyzed the internal structure of current transformer and voltage transformer, discussed the common faults and causes, which combined with the application of infrared thermometric technology. The abnormal heating fault of transformer are researched and summarized such as the poor internal contact, increased dielectric loss and abnormal secondary connection terminals, etc. The abnormal heating reason are analyzed according to the related testing data, and give out the processing scheme. The corresponding faults are established, it provide a reference for the causes and types of abnormal heating faults in transformer.
