Description

[0001] The utility model relates to a combined insulator for bypass cable connection, belonging to the technical field of electric power. Background Art
[0002] With the implementation of the requirement of "continuous power supply", more and more construction, emergency repair and operation and maintenance are carried out in the way of live working. Bypass operation and power generation operation need to introduce cables on the original equipment, and there are extremely high requirements for the selection of access points.
[0003] In the normal process of replacing pole-mounted switches and power generation and power supply protection operations, it is necessary to strip the insulating layer of the overhead insulated wire and then connect the bypass cable or the shunt wire to the conductor part. After the work is completed, the insulating layer of the overhead wire is restored with insulating tape.
[0004] In some scenarios where the outgoing sides of pole-mounted switches and pole-mounted transformers are power cables, due to the limitation of the access point, it is difficult for the bypass cable to play a role, because once the insulating layer of the power cable is damaged, it will be difficult to restore.
[0005] According to the specification requirements, after the small jib crane lifts the wire, the insulating bucket is not allowed to move. Therefore, the electrician in the bucket cannot adjust the working position when replacing the insulator, and the limitation of the working position will greatly affect the safety and convenience of the operation.
