Abstract

The invention relates to electrical engineering and can be used to fasten the wires of overhead transmission lines of various voltage classes. The goal is to simplify the design and installation. The clamp contains a boat 2 with vertical cheeks 3, a suspension in the form of a U-shaped bracket 9 with a spherical socket 10, open from the side of the vertical cheeks Z. On each cheek 3, an annular protrusion 11 located along the horizontal axis 5 of the suspension is executed. A hole 12 located along the vertical axis 13 of the bracket 9 and a side groove 14 are formed in the recess 10, the cheeks 3 of the boats 1 are located relative to the recess 10 so that they overlap the tank groove 14 by at least 1/4 heights. The goal is achieved by the introduction of a U-shaped bracket, g-performance and location. 2 Il. S (l

WITH

The invention relates to the field of electrical engineering and can be used to fasten the wires of overhead power lines of various voltage classes.

The purpose of the invention is to simplify the design and installation.

Fig. 1 shows a supporting clip for wires of an overhead transmission line, side view (along the wires 3 of the split phase), in Fig. 2 the upper part of the device is a front view.

The supporting clamp for wires 1 of the overhead power line comprises a boat 2 with vertical cheeks 3 in which coaxial holes 4 are made, a horizontal axis 5 located in the holes 4 of the vertical cheeks 3, and a pushing device 6 fixed in the slot 7 of the boat 2 filled in its base 8 The clip suspension is made in the form of a U-about different bracket 9 with a spherical protrusion 10 in the upper part, unlocked on the side of the vertical cheeks 3 of the boat 2. The U-shaped bracket is mounted on the horizontal axis 5 and covers the vertical cheeks 3 boat 2. On each of the vertical cheeks 3 of the boat 2, an annular protrusion 11 is arranged, which is located around the horizontal axis 5. On the spherical protrusion 10 of the U-shaped bracket 9, a hole 12 is formed, which is located on the vertical axis 13 of the bracket 9, and The horizontal part of the rectangular shape with rounded edges and the vertical part of a smaller width and connected to the hole 12 on the spherical protrusion 10. The vertical cheeks 3 of the boats 2 are positioned relative to the spherical protrusion 10 in such a way that they provide ekrytie said lateral groove 14 is not less than 1/4 of its height. The pressing device 6 of the supporting clamp for the wires of the overhead transmission line is performed by any acceptable design, for example, in the form of dies 15 bolted by 1 & and mounted in the base 8 of the boat 2, where the corresponding groove 7 is made.

When assembled (with an isolator) between the pestle 17 of the insulator 17 (not shown) and the ends of the vertical cheeks 3 of the boat 2, there is a gap L equal to

2-3 mm for the required mobility of the hinge, while the lateral groove 14 through which the insulator pestle 17 is inserted partially overlaps with the vertical cheeks 3 of the boat 2. The overlap amount C corresponds to the height of the spring lock, which is now excluded from the configuration supported by i of the clamping clamp, thereby preventing the splitting of the boat 2 of the clamp with the pestle 17 of the insulator. The mounting clamp is mounted in the following sequence.

On base 8 (bottom) of boat 2, wire 1 is laid, then pressure device 6 is installed in groove 7 of base 8 of boat 2 and dies 15 are stacked on wire 1 with bolts 16. A U-shaped clip 9 is installed on insulator pestle 17 and then it is connected by means of a horizontal axis 5 to the vertical 5 cheeks of the 3 boats (screwed | Nut 18 and pin 29 is installed).

The device is designed to suspend the wires of overhead transmission lines with a voltage of 35-110 kV.

With the use of these clips, material consumption is reduced, since the spring lock is excluded from the design to lock the pestle of the insulator in the clip suspension. In addition, the manufacturability is improved, since the half plate can be made by simple methods of casting or stamping, the construction height of the suspension is reduced by making the U-shaped bracket instead of the lug and the possibility of approaching the vertical cheeks of the boat to the spherical nest of the bracket and blocking the lateral groove . Due to the use of standard parts and structural elements, the device is easy to assemble and manufacture.
