【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.更多还原
