The rapid increase of power grid load has given rise to the heating problem of operating disconnectors and con-sequently seriously threatened the stable operation of power system.This paper reports a typical case of heating fault en-countered by an actual disconnector,entailing the comprehensive causal analysis by means of infrared detection,appear-ance inspection,disintegration inspection,and electrical test,as well as the proposal of specific countermeasures to pre-vent operating disconnectors from heating faults.
