Development of 66kV Isolation Switch V Type Porcelain Column Fracture Insulation Protection Frame

The mechanical strength of old 66kV disconnect switches (V-type porcelain column type) in outdoor substations has been affected by weather and daily operation for a long time, the change internal force caused external during open closed circuit is very likely to cause fracture, which poses safety hazard people equipment. In order ensure personal equipment maintenance switch, this paper proposes kind insulation protection frame disconnecting switch V-type fracture. simple structure, flexible operation, reliability protective have proved practice that after using work, efficiency work obviously improved effectively guaranteed.
