| Abstract: | Heat emitting due to resistance deterioration and surface contamination of high voltage insulator is related to the voltage distribution of the insulator strings,it is important both for engineering design and the practical test to study the relationship of the voltage distribution and surface temperature rise of insulator strings.By using the equivalent circuit model of insulator,the voltage distribution of voltage insulator strings and its influencing factors are discussed,and then the relationship between the voltage distribution and the surface temperature rise of the insulator strings is discussed.The conclusions will be certain significance for infrared detection and diagnosis of the insulator fault. |
