As for the frequent accidents of shunt capacitor bank heating in a 500 kV substation at southern grid in Hebei Province
the statistics on heating of shunt capacitor bank in recent 2 years is made. It is considered that the main reason leading frequent heating of shunt capacitor bank is in the treatment processing technology of the joint contacting surface. Through analysis of heating infrared images and the heated contacting surfaces
the misunderstanding existing in the treatment of contacting surface is pointed out
the correct treatment process and a kind of new connection mode are proposed. Good results are achieved in the maintenance and defect elimination.
