| Abstract: | This paper analyzes a 500kV high-voltage shunt reactor fault accident.According to the inspection of primary and secondary equipment,combined with the results of on-site equipment disassembly,it is judged that the cause of the fault is the aging failure of the top cable-through gasket of the high-voltage casing and the reduction of insulation by moisture inside the casing,which triggers the grounding short circuit of the high-resistance winding.The preventive measures are presented. |
