| Abstract: | Combining with the case of medium voltage bushing of phase C No. 1 main substation forJinfeng 220 kV substation, the causes and treatment process were introduced. By the comprehensiveanalysis of the high voltage bushing disassembling and infrared thermal imaging test, the causes wereconfirmed that the high voltage bushing heating and the initial influence on the heating place judge-ment by the operators, and the concrete suggestions were proposed for the treatment to improve thereliability of the operating equipment. |
