Development of 66kV New Rotating Grounding Insulating Rod

the conventional 66kV grounding insulating rod hanging and dismantling the grounding wire can not meet the maintenance of 66kV power cut transmission lines and equipment in a variety of tower types and operation positions. In order to meet the maintenance of transmission lines and equipment in various environments of 66kV power failure, a new 66kV rotatable grounding insulating rod will be developed in this paper, which will be improved and innovated in the two directions of chain and PTZ structure. Through the comparative and comparative experimental methods, the experimental results show that the PTZ structure is adopted as a new 66kV rotatable grounding insulating rod from the perspectives of efficiency, safety and economy. The improvement scheme shortens the time of hanging and removing the grounding wire for 66kV power outage maintenance, greatly reduces the operation difficulty, improves the operation efficiency, and further improves the safety of personnel, power network and equipment.
