Description

Flexible wire shielding cover Technical Field The invention relates to the technical field of safety protection equipment for live working of a power distribution network, in particular to a flexible wire shielding cover. Background In the live working process of the power distribution network, the insulation isolation of live wires is a core link for guaranteeing personal safety of operators and smooth operation development. The safety operation boundary is constructed through the wire shielding cover, so that the short circuit between the live wire and the grounding body, between the live wire and different potential components or between the live wire and the working tool can be effectively prevented, and meanwhile, the electric shock accident caused by the fact that personnel touch the live body by mistake is avoided, so that the live wire shielding cover is indispensable safety protection equipment for live operation. According to the difference of operation modes, the existing wire shielding covers are mainly divided into two types, namely a wire shielding cover for a glove operation method and a wire shielding cover for an insulating rod operation method. The wire shielding cover for the glove operation method is specially designed for an operator to wear insulating gloves to directly operate, is made of hard PE materials, but is not adaptive to the operation of an insulating rod in structure, cannot meet the use requirement of the insulating rod for remote operation, consists of a hard PE pipe and a hardware clamp, is adaptive to a remote operation scene of the insulating rod, and has the obvious defects that firstly, the weight is heavy, the weight of a single sleeve is usually about 2.1kg, when the operator lifts the insulating rod, the load is born for a long time, arm fatigue and shaking are easily caused, the operation accuracy is further reduced, secondly, the bayonet design is too tight, larger external force is required to be applied for opening and closing, the difficulty of force generation is large when the insulating rod is controlled remotely, bayonet closure can be completed by repeatedly adjusting the angle of the insulating rod, the operation is complicated, the operation is time is consuming, and the operation efficiency is often seriously influenced. Therefore, there is a need to develop a novel wire shielding cover capable of overcoming the above-mentioned drawbacks to improve the safety, convenience and efficiency of the live working of the power distribution network.
