Description

A parallel ditch wire clamp insulation shield

technical field

The invention belongs to the technical field of electric power system auxiliary equipment, and in particular relates to an insulating shield for parallel trench line clamps.

Background technique

In the power system, through the statistical analysis of bird damage faults on the 10Kv distribution network, it is found that the equipment that causes the fault is mainly concentrated on the weak single equipment such as the wire connection of the tension pole and the high-voltage knife switch, among which the tension pole The main reason for the fault at the wire connecting point is that the parallel trench clamp is not fully insulated. The parallel trench clamp is a device that uses a splint to overlap two cables together. This is one of the main faults that cause power failures in power supply facilities. , has brought influence to enterprise and resident's electricity consumption, so how to put an end to the bird damage fault that occurs at the parallel ditch line clip place has become the important subject before those skilled in the art.

Contents of the invention

In order to solve the above problems, the object of the present invention is to provide an insulating shield for parallel-groove clamps that can be installed without power failure.

In order to achieve the above-mentioned purpose, the insulating shield of the parallel trench clamp provided by the present invention is made of a soft insulating rubber sheet, which includes a top and two side parts; wherein the top is a cuboid structure with an open lower end; the two side parts The structure is relatively symmetrical, and both the inner side and the bottom surface are open-shaped cuboid structures. The upper ends of the two sides are symmetrically connected to the opening edge of the top, and a cable through hole is formed on the front and rear end faces, and the cable through hole A gap is formed on the edge close to the opening, and two installation tool insertion holes are formed on the lower end of the outer surface.

The edge of the cable through hole protrudes outward.

The cable through-hole is a round hole, and its diameter is equal to the outer diameter of the cable on the parallel groove clamp.

The insulating cover of the parallel trench wire clamp provided by the invention can realize live installation, so the installation process is simple and timely. In addition, it is made of soft insulating rubber sheet, which can be completely attached and covered on the surface of the parallel trench clamp, so it can prevent birds from nesting on the parallel trench clamp, which will cause problems such as distribution line failures. In addition, the insulating cover of the parallel trench line clamp has the advantages of reasonable and simple structural design, convenient installation and the like.

Detailed ways

The parallel trench wire clamp insulating shield provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in Fig. 1-Fig. 3, the insulation cover of parallel trench clamp provided by the present invention is made of soft insulating rubber sheet, which includes a top 1 and two side parts 2; wherein the top 1 is a cuboid with an open lower end Shaped structure; the structures of the two side parts 2 are relatively symmetrical, and both the inner side and the bottom surface are open cuboid structures. The upper ends of the two side parts 2 are symmetrically connected to the opening edge of the top 1, and a The cable through hole 3 has a gap 4 formed on the edge of the cable through hole 3 close to the opening, and two installation tool insertion holes 5 are formed at the lower end of the outer surface.

The edge of the cable through hole 3 protrudes outward.

The cable through-hole 3 is a round hole, and its diameter is equal to the outer diameter of the cable on the parallel groove clamp.

Now, the method for installing the insulation shield of the parallel trench clamp provided by the present invention is described as follows: the installation needs to be carried out by using the insulation installation rod head 6 shown in Figure 4 and Figure 5, and the insulation installation rod head 6 includes the main rod 7 and the suspension part 8, wherein four hooks 9 are provided on the hanging part 8. Firstly, the maintenance personnel will insert the four hooks 9 on the insulation installation rod head 6 from the outside into the four installation tools on the insulating cover of the parallel trench line clamp and insert them into the holes 5, and then screw the rear end of the main rod 7 At the upper end of the insulation operating rod 10 commonly used in maintenance work at present, then go up to the height near the place where the parallel ditch line clamp is set, and then lift the insulation operation rod, the insulation installation rod head 6 and the insulation shield of the parallel ditch line clamp until the parallel ditch line Clamp the insulating shield close to the parallel groove clamp, then place the top 1 on the top outside of the upper splint of the parallel groove clamp, and make the two cables at the front and rear ends of the parallel groove clamp upper splint enter the corresponding cables through the gap 4 Through the inside of the hole 3, and then pull the insulation installation rod head 6 backward, so that the two hooks 9 at the rear end withdraw from the two corresponding installation tool insertion holes 5 on the insulation shield of the parallel trench clamp, and then push the insulation installation forward. Rod head 6, so that the two hooks 9 at the front end are withdrawn from the two corresponding installation tool insertion holes 5 on the insulating shield of the ditch cable clamp, and finally the edges of the side part 2 and the cable through hole 3 are arranged with the front end hook 9 Well, make it fit tightly on the plywood of the parallel groove clamp and the surface of the root of the cable to complete the entire installation process.
