Switching Tests of Energized GIS Disconnectors in UHV AC Pilot Demonstration Project
摘要
Abstract
In order to verify the safety of switching of gas insulated switchgear （GIS） disconnectors energized in ultra high voltage（UHV） AC Pilot Demonstration Project, we experimentally investigated switching of all GIS disconnectors energized in Changzhi, Nanyang, and Jingmen substations, and monitored very fast transient overvoltage （VFTO） and transient enclosure voltage （TEV） generated . The tests results show that switching of UHV GIS disconnectors energized is safe, the effect of TEV on secondary equipment should be paid attention to, and damping resistor in disconnector can mitigate VFTO and TEV significantly, The tests provide technical support for the future switching of GIS disconnector energized in UHV substations.关键词
