Description

Insulation isolation bar for live work

technical field

The utility model belongs to the technical field of power line maintenance tools, and in particular relates to a spacer rod used for live replacement of insulators on transmission lines.

Background technique

The maintenance of power lines sometimes requires live replacement of insulators. In the existing operation, it is usually to utilize the wire tightening machine to operate. When in use, first connect the wire tensioner to the live wire at the rear end of the insulator to be replaced, and then use an insulating rope to connect the wire tensioner to the tower pole to operate. The problem is that there is only an insulating rope between the live wire and the tower pole for single-layer insulation protection. The insulating rope is often damp due to the weather, and the damp insulating rope is prone to insulation breakdown, resulting in equipment and personal safety accidents. .

Contents of the invention

The technical problem to be solved by the utility model is to provide an isolating device for live line insulator replacement with good safety performance and convenient use.

In order to solve the above-mentioned technical problems, the utility model includes an insulating rod, and its structural feature is that the two ends of the insulating rod are provided with connecting members, and the body of the insulating rod is provided with an umbrella skirt.

Preferably, the connecting members at both ends of the insulating rod are hooks and collars respectively.

It is further preferred that the two ends of the insulating rod are provided with insertion ports, the connecting member is plugged and fixed with the two ends of the insulating rod, and the rod body between the two ends is a solid structure.

Another preferred method is that 3-5 sheds are arranged on the rod body of the insulating rod, and sheds with different diameters are arranged alternately on the rod body of the insulating rod.

The hook includes a hook and a hook handle hinged together, and the hook handle is tightly connected with the insulating rod.

The beneficial effect of the utility model lies in that the utility model is composed of an insulating rod and connecting members arranged at both ends thereof, and the rod body of the insulating rod is provided with an umbrella skirt which increases the creepage distance. When in use, the insulating rod replaces the original insulating rope, and the connecting members at both ends are respectively connected with the rod body of the transmission line and the live line. Not only is it easy to use, but also has good insulation and isolation performance, which can effectively prevent insulation breakdown problems caused by high air humidity and other reasons, and is safe to use.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the overall schematic diagram of the utility model;

Fig. 2 is a sectional view of the utility model.

Detailed ways

Referring to the accompanying drawings, the live working insulation isolation rod includes a silicone rubber insulation rod 1, and an insertion port is provided at both ends of the insulation rod 1, and the rod body between the two ends is a solid structure. The rod body of the insulating rod 1 is provided with 3-5 sheds 11, and the sheds 11 have different diameters, and the sheds 11 with different diameters are arranged alternately on the rod body of the insulating rod 1. The sockets at both ends of the insulating rod 1 are plugged with a connecting member 2, which is a hook 21 and a collar 22 respectively. Solid connection, the collar and the ring handle that the collar 22 is connected together, the ring handle is firmly connected with the other end of the insulating rod 1.

When in use, the hook 21 of the utility model is connected with the rod body of the transmission line, and the collar 22 is connected with the wire tightener and then connected with the line to be replaced with an insulator; Insulation isolation effect.
