Abstract

The special tool for hanging the ground wire is used for the three-phase line of the power transmission line, including the ground wire connection device and the insulating telescopic operating rod. One of the hooks is facing upwards, the other is facing downwards, and the downward hook is located at the top of the insulated telescopic operating rod; After the improvement of the grounding wire, use an operating lever equipped with a hook to hook the ring on the top of the grounding wire clamp to complete the suspension and disassembly of the three-phase grounding wire, saving time, effort and safety , efficient.

Description

Special tool for ground wire suspension

technical field

The utility model relates to the field of equipment for electric power construction, in particular to a ground wire suspension tool.

Background technique

When grounding wires are used for power outage operations on towers of 110kV and above, each phase of the existing grounding wires is equipped with an operating rod and an extension rod. It is very inconvenient to carry so many parts; When the grounding wire is used, since the insulator is placed horizontally, whether the grounding wire is suspended or removed, the grounding wire clip hook and the wire hanging point are at a horizontal angle, and the connection is not firm, and the wire clip hook is easily damaged when hanging.

Utility model content

The purpose of the utility model is to provide a special tool for hanging the grounding wire, which is easy to carry, especially convenient for hanging the grounding wire on the tension tower, and improves the working efficiency.

The technical scheme of the utility model is:

The special tool for hanging the ground wire is used for the three-phase line of the power transmission line, including the ground wire connection device and the insulating telescopic operating rod. One of the hooks is facing upwards, the other is facing downwards, and the downward hook is located on the top of the insulated telescopic operating rod; The ground wire clip is connected with the touch-type ground wire clamp, and the lower ends of the three ground wire connection wires are connected to the fixed end of the ground wire after being connected.

The rod body of the insulated telescoping lever is made of lightweight insulating composite material.

The utility model has the advantages of:

1. Install the hanging ring on the top of the grounding wire clamp, and install the hook on the operating rod.

2. Light in weight, suitable in length, easy to be transported by vehicle and carried by people.

3. After the improvement of the grounding wire is completed, it is convenient to hang the grounding wire to the hanging point smoothly, especially for the suspension and disassembly of the tension tower.

After the improvement of the grounding wire, the suspension and disassembly of the three-phase grounding wire can be completed by hooking an operating lever equipped with a hook to the hanging ring on the top of the grounding wire clip, which saves time and effort, is safe and efficient.

Fig. 1 is the structural representation of the utility model.

detailed description

As shown in Figure 1, the special tool for ground wire suspension of the present utility model is used for three-phase lines of power transmission lines, and includes a ground wire connection device and an insulating telescopic operating rod 1. The insulating telescopic operating rod 1 is a telescopic structure, and the insulating telescopic operation There is a hook on both sides of the top of the rod: the first hook 3 and the second hook 4, wherein the hook of the first hook 3 faces upward, the hook of the second hook 4 faces downward and the second hook 4 is located on the insulating telescopic operating rod 1 top of the . The ground wire connecting device includes three hanging rings 2, and the lower end of each hanging ring 2 is connected with a touch-type ground wire clamp 5, and the touch-type ground wire clamp 5 is connected with a ground wire connecting wire 6, and three ground wire connecting wires After the lower end of 6 is connected, it is connected with the fixed end 7 of the ground wire.

The rod body of the insulating telescopic operating rod 1 is made of lightweight insulating composite material.

Use process:

The duckbill type touch-type ground clamp 5 is directly connected to the ground wire 6 (copper wire ground wire), and the length of the soft copper wire is determined by the standard distance without the operating rod. Add a hanging ring 2 to the top of the clamp of the grounding wire. An operation rod 1 that is easy to carry and has a suitable length. The front part of the rod is equipped with hooks 3 and 4 that are suitable for horizontal suspension of tension towers and vertical suspension of straight towers. The line is sent to the hanging point for hanging or detaching. The suspension of the three-phase grounding wire can be completed with one operating rod, which saves two operating rods 1 and makes the work more convenient.
