Abstract

The utility model discloses a ground wire clamp for testing, which belongs to the field of power transmission. Including the clamp body, the clamp body is fixed with bolts, the threaded hole is provided on the lower side plate of the clamp body, the rotating part is arranged in the threaded hole, the fastener is provided at the top of the rotating part, and the inner side of the upper side plate of the cable clamp body is provided. There are sawtooth, and said sawtooth includes triangular sawtooth and rectangular sawtooth. In the utility model, the sawtooth on the inner side of the upper side plate of the clamp body is arranged in a triangle and a rectangle at intervals. The bottom of the triangular sawtooth is relatively sharp, which can grind off the insulating layer on the grounding down-conductor, while the rectangular sawtooth can make the clamp and the grounding The contact between the down conductors is relatively good.

Description

Test ground clamp

technical field

The utility model belongs to the field of power transmission, in particular to a grounding clamp for experiments.

Background technique

In the process of overhauling and maintaining electric equipment, grounding wire clamps need to be fixed on the grounding down conductors. The existing grounding wire clamps are shown in Figure 1, including the wire clamp body 2, and the wire clamp body 2 is fixed with bolts 6. There is a threaded hole on the lower side plate of the clamp body 2, a rotating part 7 is arranged in the threaded hole, a fastener 3 is provided on the top of the rotating part 7, and a sawtooth is provided on the inner side of the upper side plate of the cable clamp body 2. The saw teeth are all in the shape of a triangle. When the surface of the grounding down conductor is oxidized or has an insulating layer such as spray paint on the surface, by moving the grounding clamp, use the triangular sharp sawtooth to grind off the insulating layer on the surface of the grounding down conductor 1. The connection between the clamp and the grounding down-conductor 1, but due to point contact or line contact between the bottom end of the triangular sawtooth and the grounding down-conductor, the contact between the clamp and the grounding down-conductor 1 is still unsatisfactory.

Utility model content

The technical problem to be solved by the utility model is that the contact between the grounding wire clip and the grounding down conductor is not good, and a grounding wire clamp for testing that can be in good contact with the grounding down wire is provided.

The technical scheme of the utility model is realized in the following manner:

A grounding clamp for testing, comprising a clamp body, on which a bolt is fixed, a threaded hole is provided on the lower side plate of the clamp body, a rotating part is arranged in the threaded hole, and a fastener is provided on the top of the rotating part. Serrations are provided on the inner side of the upper side plate of the clamp body, and the serrations include triangular serrations and rectangular serrations.

The triangular sawtooth and rectangular sawtooth are distributed at intervals.

The top surface of the fastener is provided with triangular serrations and rectangular serrations distributed at intervals.

In the utility model, the serrations on the inner side of the upper side plate of the clamp body are arranged at intervals of triangles and rectangles, and the bottom of the triangular serrations is relatively sharp, which can grind off the insulating layer on the grounding down-conductor, while the rectangular serrations can make the clamp and the grounding The contact between the down conductors is relatively good.

Detailed ways

Example 1

As shown in Figure 2, this embodiment includes a clamp body 2, on which a bolt 6 is fixed, a threaded hole is provided on the lower side plate of the clamp body 2, a rotating part 7 is arranged in the threaded hole, and a rotating part 7 A fastener 3 is provided at the top, and serrations are provided on the inner side of the upper side plate of the clamp body 2 , and the serrations include triangular serrations 5 and rectangular serrations 4 . The triangular sawtooth 5 and the rectangular sawtooth 4 are distributed at intervals.

The application process of the utility model is as follows: put the grounding down conductor 1 above the fastener 3, twist the rotating part 7 to move the fastener 3 upwards, clamp the grounding down conductor, if the surface of the grounding down conductor 1 has Insulating layer, then move the clamp body left and right, use the triangular sawtooth 5 to grind off the insulating layer, so that there is good contact between the clamp and the grounding down conductor.

Example 2

As shown in FIG. 3 , the top surface of the fastener 3 is provided with triangular saw teeth 5 and rectangular saw teeth 4 distributed at intervals. Other structures and implementations are the same as in Example 1. the
