Technical Field

[0001] This utility model relates to the field of lightning protection wire support technology, and in particular to a lightning protection wire support used for overhead single-circuit power distribution lines. Background Technology

[0002] An overhead lightning protection wire is a grounding device that connects the support poles of an overhead power line to the ground via a conductor, thereby grounding the line to the earth. Its function is to protect the lines and equipment from lightning strikes by diverting electrical charges to the ground during thunderstorms.

[0003] Traditional overhead lightning protection wires have a relatively complex structure and are difficult to install, making it inconvenient for users to install grounding leads. Therefore, there is an urgent need for a lightning protection wire bracket for single-circuit overhead power distribution lines. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lightning protection wire support for overhead single-circuit power distribution lines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A lightning protection wire support for a single-circuit overhead power distribution line includes a lightning protection pole top support, which is divided into a middle support and a terminal support, both of which are installed on a column. Both the middle support and the terminal support are equipped with U-shaped hanging rings, and the bottom of the U-shaped hanging rings is equipped with suspension clamps. An aluminum-clad steel strand is inserted into the pole top bracket on the terminal bracket, and a lead-in strand is inserted into the suspension clamp. The aluminum-clad steel strand and the lead-in strand are connected by a parallel groove clamp. An aluminum-clad steel strand is inserted into the suspension clamp on the middle support, and a drain strand is inserted into the pole top support. The aluminum-clad steel strand and the drain strand are connected by a parallel groove clamp.

[0006] In addition, a preferred structure is that aluminum sheathing is provided on both sides of the suspension clamp, and the aluminum-clad steel strand or the drain strand passes through the aluminum sheathing.

[0007] In addition, a preferred structure is that multiple grounding terminals are fixedly installed on the top support of the lightning protection pole, and the current-carrying strands all pass through the grounding terminals.

[0008] In addition, in a preferred configuration, the other end of each of the current-draining strands is connected to a grounding round steel, and a grounding terminal is adapted to be provided on the grounding round steel corresponding to each current-draining strand.

[0009] Furthermore, in a preferred configuration, hydraulic tension wires are provided on both sides of the pole top support on the terminal bracket, and the hydraulic tension wires are all installed via U-shaped hanging rings.

[0010] Furthermore, in a preferred configuration, the terminal supports are installed at both ends of the aluminum-clad steel strand, and the middle support is installed in the middle of the aluminum-clad steel strand.

[0011] The beneficial effects of this utility model are as follows: by setting up the terminal bracket and the middle bracket, multiple current-draining stranded wires and aluminum-clad steel stranded wires can be connected together by parallel groove clamps, and all current-draining stranded wires can be connected and installed together with the grounding round steel through the grounding wire terminal. In this way, the grounding wire of the aluminum-clad steel stranded wire can be installed, and the installation method is simple and convenient, making it easy for users to operate.

The other end of each current-carrying strand 6 is connected to a grounding round steel 9, and a grounding terminal 8 is adapted to each current-carrying strand 6 on the grounding round steel 9.

[0024] Then, the second drain wire 6 is passed through the terminal bracket and connected to the grounding round steel 9 through the grounding terminal 8. Then, the first drain wire 6 and the second drain wire 6 are connected together through the parallel groove clamp 7.

[0025] Next, pass the aluminum-clad steel stranded wire 10 through the suspension clamp 4 on the middle support, then pass the first current-draining stranded wire 6 on the terminal support through the middle support, and connect it to the grounding round steel 9 through the grounding terminal 8.
