Description

A ground wire end with adjustable angle

technical field

The utility model relates to the field of electric equipment, in particular to an angle-adjustable ground wire end.

Background technique

In the maintenance work of 35-220kV high-voltage transmission lines, hanging and removing the grounding wire is an important step and means to ensure the safety of maintenance workers. According to the previous experience in maintenance operations and the situation of hanging the ground wire on site, there are still hidden dangers that threaten the safety of operators. The end of the existing grounding wire and the insulating rod are a fixed integral structure, which cannot meet the safety requirements for hanging and removing the grounding wire on some tension poles, and restricts the flexibility of the operator's operation.

The existing wire terminals mainly have the following problems:

1. The grounding wire is hung upside down in the vertical direction of the straight pole tower. With the vibration of the wire, the grounding wire may be separated from the wire and the grounding protection will be lost;

2. The grounding wire is hung horizontally on the tension tower, and the grounding wire end is at an angle to the wire. In fact, the grounding wire end is not in close contact with the wire, resulting in low grounding efficiency between the grounding wire and the tower, posing a safety hazard;

3. The grounding wire of the tension pole tower is hung vertically on the drainage wire. When removing the grounding wire, the drainage wire moves back and forth together with the grounding wire, and it is difficult to disengage. If the grounding wire is removed abruptly, it will damage the aluminum strand of the wire or cause the bolts of the parallel groove clamp to loosen. , resulting in drainage failure.

Utility model content

The purpose of the utility model is to provide an angle-adjustable ground wire end to solve the above-mentioned defects in the prior art.

An angle-adjustable grounding wire end, including an integrally formed metal hook and grounding copper wire, the grounding copper wire is connected to the side of the tail of the hook through bolts, and the inner side of the hook is provided with two symmetrically arranged elastic clips , The tail of the hook is welded with a U-shaped joint, and a connecting rod is riveted in the U-shaped joint, and an insulating operating rod is connected to the connecting rod by connecting bolts for rotation.

Preferably, a section of insulating sleeve is provided near the hook on the grounding copper wire.

Preferably, two symmetrically arranged connecting pieces are connected to the top end of the insulating operating rod, and the connecting bolt passes through the connecting piece and the connecting rod and connects the connecting piece and the connecting rod through a nut.

The utility model has the advantages that: the utility model improves the quality of hanging and removing the grounding wire, ensures the effective grounding rate of the connecting wire, improves the grounding efficiency, eliminates potential safety hazards, and ensures the safety of maintenance operators.

detailed description

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

As shown in Figure 1, an angle-adjustable grounding wire end includes an integrally formed metal hook 1 and a grounding copper wire 2, the grounding copper wire 2 is connected to the side of the tail of the hook 1 by bolts, and the hook 1 The inner side is provided with two symmetrically arranged elastic clips 3, the tail of the hook 1 is welded with a U-shaped joint 4, and a connecting rod 5 is riveted inside the U-shaped joint 4, and an insulating operating rod 7 is connected to the connecting rod 5 through a connecting bolt 6 in rotation. , so that the insulating operating rod 7 can be rotated according to the position of the operator, which facilitates the disassembly and assembly of the grounding wire end, improves the quality of hanging and removing the grounding wire, ensures the effective grounding rate of the connecting wire, and improves the grounding Efficiency, eliminate potential safety hazards, and ensure the safety of maintenance operators.

In this embodiment, the ground copper wire 2 is provided with an insulating sleeve 8 close to the hook 1, which improves the insulation effect and prevents the ground copper wire 2 from contacting the connecting rod 5 too close to cause an effect. The top of 7 is connected with two symmetrically arranged connecting pieces 9, and the connecting bolt 6 passes through the connecting piece 9 and the connecting rod 5 and connects the connecting piece 9 and the connecting rod 5 through a nut.

Based on the above, the utility model facilitates the disassembly and assembly of the ends of the grounding wires, improves the quality of hanging and removing the grounding wires, ensures the effective grounding rate of the connecting wires, improves the grounding efficiency, eliminates potential safety hazards, and ensures that maintenance operators safety.

It can be known from technical knowledge that the utility model can be realized through other implementations without departing from its spirit or essential features. Accordingly, the above-disclosed embodiments are, in all respects, illustrative and not exclusive. All changes within the scope of the utility model or within the range equivalent to the utility model are included in the utility model.
