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