Study on Typical Diversion Structures and Fault of 220kV Cable-Conductor Bushings

Abstract:

According to a TOM bushing faults, three typical 220kV cable-conductor bushings (COT, TOM and BRDLW) widely used in the power grid are analyzed about diversion structure. Bushing diversion structure, diversion contact surface, current path and installation sensitivity are discussed in the paper. The study found that installation accuracy of TOM bushing has greater effect on contact resistance of diversion path than others. The improper installation of TOM bushing caused overheating defects and finally developed into this bushing fault.
