Abstract

As a new type of equipment, 220kV GIS double-break disconnect switch can effectively solve the stubborn problem of busbar outage when the GIS interval is modified and expanded. According to the technical characteristics of the double-break disconnect switch, its wiring form, equipment size versatility and other engineering applicability are discussed. Using the double busbar as a bridge and making full use of the own characteristics of the double-break busbar disconnect switch, a new test scheme is proposed, which can complete the puncture test of the double-break busbar disconnect switch at the spare interval during the first phase construction of the substation. By comparing with conventional busbar disconnect switches, the economic benefits of this type of equipment in substations are verified and it has good application prospects.
