Description

A bird-repelling lightning arrester

technical field

The utility model relates to the field of power distribution equipment, in particular to a bird-repelling lightning arrester.

Background technique

In the field of power distribution, when spring comes, there will be a period of frequent bird damage. Grounding short-circuit accidents caused by bird damage occur from time to time, resulting in power outages. Flying birds pose a great threat to the security of the power grid. In the past two years, with the improvement of the environment, the number of birds has increased, so the hidden dangers of the power grid security have also increased. In particular, lightning arresters installed on power transmission towers have become nesting grounds for more and more birds. It is known that some migratory birds will pick up metal wires to build nests, which can easily cause electrical accidents. In addition, due to the water contained in bird droppings, once it falls on the transmission line, it is easy to cause a short circuit. Installing a bird preventer and a lightning arrester on the pole and tower respectively has low efficiency, high cost and cumbersome installation.

Invention content:

The technical problem to be solved by the utility model is to provide a bird-repelling lightning arrester to prevent birds from landing on the lightning arrester and ensure the safety of the lightning arrester.

The utility model adopts following technical scheme to realize the object of the invention:

A bird-repelling lightning arrester, comprising a utility pole, characterized in that: the utility pole is connected to the lightning arrester body through a fixed rod, the upper end of the lightning arrester body is provided with a diversion ring, and the lower side of the lightning arrester body is provided with an insulating support , a group of wind chime brackets and wind chimes are arranged on the insulating platform, the bottom of the insulating platform is connected with rollers, the rollers are arranged on the insulating bracket, the insulating bracket is arranged on the utility pole, the The bottom of the insulating platform is connected to the rotating cylinder, the rotating cylinder is connected to the insulating bracket through bearings, the bottom of the rotating cylinder is connected to the vertical shaft, and the vertical shaft is connected with four evenly distributed connecting rods Each of the connecting rods is threadedly connected with a wind panel, and a grounding guide wire is arranged inside the fixed rod, one end of the grounding guide wire is connected to the arrester body, and the other end passes through the utility pole to ground.

As a further limitation of the present utility model, the guide ring is in the shape of a semicircle.

As a further limitation of the present utility model, a tightening bolt is arranged on the connecting rod.

Compared with the prior art, the advantages and positive effects of the utility model are: the utility model drives the rotation of the wind panel through the wind force, and under the function of the bearing to reduce the friction force, it quickly drives the insulation bracket to rotate, and the insulation bracket drives The wind chime rotates and makes a burst of sound, preventing the birds from landing, thereby protecting the lightning arrester from damage. Due to the tip discharge effect of the guide ring, the lightning discharges it first, and the lightning strike current is introduced into the ground through the grounding guide wire and the grounding device, thereby avoiding the occurrence of lightning around the wire and lightning strike against the utility pole. The utility model has the advantages of convenient installation and maintenance, high efficiency and low cost.

detailed description:

Below in conjunction with embodiment, further illustrate the utility model.

Referring to Fig. 1-Fig. 3, the utility model includes an electric pole 1, the electric pole 1 is connected to the arrester body 3 through the fixed rod 2, the upper end of the arrester body 3 is provided with a guide ring 4, and the lower end of the arrester body 3 An insulating pallet 5 is arranged on the side, and a group of wind chime brackets 6 and wind chimes 7 are arranged on the insulating pallet 5. The bottom of the insulating pallet 5 is connected with a roller 8, and the roller 8 is arranged on the insulating bracket 9. The insulating bracket 9 is arranged on the utility pole 1, the bottom of the insulating bracket 5 is connected to the drum 10, and the rotating drum 10 is connected to the insulating bracket 9 through a bearing 11, and the rotating drum 10 The bottom of the vertical shaft 12 is connected to the vertical shaft 12, and four evenly distributed connecting rods 14 are connected on the vertical shaft 12. Each of the connecting rods 14 is threaded with a wind panel 15, and the fixed rod 2 is provided with a A grounding guide wire 13 , one end of the grounding guide wire 13 is connected to the arrester body 3 , and the other end passes through the utility pole 1 to ground.
