Abstract
With the rapid development of the electric power projects and electrization of industrial corporations, more and more transformers have been used. When in operation, the real time supervision of Transformer Fault is very important to the secure operation of transformer. The Infrared imaging techniques played an important role in Fault diagnosing for transformer. The infrared imaging technique based on infrared radiation knowledge, by using this technique, the Fault modes of Power transform as well as the application of infrared imaging on Power transformer were studied. Then a series of practical engineering problems, such as the image shaping principle of infrared laser device, the utilizing of infrared laser device in power transformer fault diagnosis, the working procedure in real field operation, the acquiring of heat spectrum from fault transformer in field test, the analyzing of heat image spectrum etc, were considered and overcame. Finally, an example was presented by using the studied infrared heat imaging technique to diagnose the primary transformer at Baitaling substation. The results are closely according with the real situation.
