Research and Development of High Voltage Lead-in Device for Gas Insulated Switchgear Insulation Level Test
The inner-cone or outer-cone bushings are always used as high voltage lead-in interface for gas insulated switchgear in insulation level tests.The high voltage lead-in devices normally includes the high voltage test cable
the epoxy casting inner-cone voltage adapter etc..Propose a new silicone rubber insulated high voltage adapter design which is applicable of high voltage leading interface for insulation level test of various C-GIS or other gas insulated switchgear.This design has the advantages of simple structure
low manufacturing cost
convenient and fast installation
as well as it has been widely used in the application of factory routine test
delivery test and acceptation tests on site of gas insulated switchgear as the high voltage lead-in device.
