Study on the Influence of Internal Discharge on Temperature Distribution in Complex-insulation System
【摘要】 研究了复合绝缘系统中内部放电的热效应及双层复合绝缘结构在高压电场作用下,内部气隙产生放电对绝缘系统热分布的影响,在传热学的基础上建立内部放电能量与温度的对应关系,并借助于计算机对包含缺陷的绝缘系统的热分布进行了计算,讨论了基于热效应进行复合绝缘结构诊断的新方法。
【Abstract】 In this paper, the thermal effect of internal discharge in complex insulation system is investigated, and the influence of internal discharge due to inner voids on the thermal distribution in double-layer insulation construction under high-voltage is studied emphatically. A relationship between the energy of internal discharge and temperature distribution based on the theory of heat-transfer is presented, and the thermal distribution of insulation system including known defects is calculated by the help of computer. Finally, the diagnoses of complex-insulation system based on the thermal effect of internal discharge are discussed.
