摘要：This paper deals with the electric field characteristics in the inter-phasesregion of three-phase gas insulated switchgear (GIS). The electric field in a three-phaseconstruction of a simplified GIS model was analyzed. The results show that in the interphasesregion the direction and the magnitude of electric field vector varies with thelocation of the observation point while in the phase-enclosure region the direction of theelectric field vector tends to linear and constant. There is no zero electric field on theparticle tip of a particle in the inter-phases region, except S90 particle. There is zeroelectric field on the particle tip of a particle in the phase-enclosure region every halfcycle of applied voltage. The maximum electric field of the particles on the inter-phasesregion generally is higher than one of the particles on the phase-enclosure region. Theelectric field vector locus in the inter-phases region varies: linear, elliptic, or circularwhile one in phase-enclosure region is constant and linear.
