Research on Partial Discharge Detection Technology for 110 kV GIS Basin-Type Insulators
Gas insulated metal enclosed composite electrical appliances have been widely used in China's power en-gineering due to their advantages such as small footprint,high reliability,convenient installation,and simple opera-tion.However,due to the compact structure,narrow internal space,and concentrated electric field of Gas Insulated Switchgear(GIS),process issues during installation may cause burrs and metal particles,leading to partial discharge and equipment safety accidents.Regarding the partial discharge situation of 110 kV GIS basin-type insulators,based on a certain detection case,this paper analyzes the partial discharge positioning method for 110 kV GIS basin-type insulators,including signal amplitude comparison,signal sequence comparison,and time difference calculation.It also elaborates on partial discharge detection techniques of standard lightning,oscillating lightning impulse,and opti-cal inspection technology.
