Basic Or The Infrared Thermovision Technics To The Diagnosis To The Inside Breakdown In The Transformer

On the basis of the diagnosis of interior breakdown in the transformer using the technique of infrared thermovision, this paper explores the theory and use of the technique of infrared thermovision by expounding the inner structure and the mechanism caused by the breakdown of transformer .In addition, the author applies the theory of heat conduction to define the nature and location of inside breakdown of the transformer by means of the data obtained from the distribution of surface temperature on the transformer measured by the infrared thermovior .therefore it provides theoretical basis for accomplishing a predictable maintenance to the transformer as well as a research approach to the diagnosis to the inside breakdown in the transformer.
