Application of Double-Gap Disconnector in 220 kV GIS Substation
With the increasing demand for power supply reliability and sustainability in the power grid system,in order to achieve uninterrupted expansion,maintenance,and on-site insulation testing of existing substations,it is necessary to use a double-gap disconnector in conjunction with a temporary earthing switch to effectively solve these problems.At the same time,through the reasonable design of the double break isolation switch structure,it can effectively be compatible with existing equipment and intervals,improve equipment interchangeability and later maintainability.
