They play an important role in power transmission and transformation projects to ensure the safe operation of the power grid system. Among them, the grading ring belongs to the anti-interference type electric power fitting. The grading ring is an electric power fitting used to control corona discharge, reduce radio interference, and improve the voltage distribution of the insulator string. It reduces or resists external electromagnetic interference through the anti-interference characteristics of the grading ring, thereby improving the stability and reliability of the power system.

[0003] For example, the application number CN208970246U discloses a bird-proof grading ring. Aiming at the problem that the feces discharged by birds cause the porcelain bottle to accumulate stains, resulting in a decrease in the surface insulation strength of the porcelain bottle and a line trip, a connecting body is fixedly arranged inside the grading ring body. A fixing device is fixedly arranged on the connecting body. Fixing holes are opened on the side of the fixing device. A sound and light bird repelling device is also arranged on the fixing device; a support rod is fixedly arranged on the grading ring body. A wind turbine is arranged at the upper end of the support rod. The power output end of the wind turbine is electrically connected to the sound and light bird repelling device. This device is installed on the top of the insulator. The connecting body prevents bird droppings from falling onto the insulator through the shielding effect. The sound and light bird repelling device can effectively prevent birds from approaching. This device has a simple structure, is convenient to manufacture and install. It can not only achieve the due function of the grading ring, but also effectively prevent bird droppings from polluting. This bird-proof grading ring can effectively prevent birds from approaching and avoid the accumulation of stains on the porcelain bottle caused by the feces discharged by birds.

[0004] However, this grading ring is usually welded by two annular objects. After welding, the grading ring occupies a large area and requires too much space during transportation, thus causing the problem of increased transportation costs.

A connecting plate 212 is fixedly arranged on one side of the annular clamping plate 211. Hole grooves 213 are symmetrically arranged on the annular clamping plate 211. Fixing rods 214 are threadedly connected in the hole grooves 213, and the fixing rods 214 penetrate out of the inside of the hole grooves 213. The annular clamping plates 211 are movably installed on the connecting columns 21. When it is convenient to assemble the power fitting, it is convenient to assemble the power fitting by installing the annular clamping plates 211. First, clamp the annular clamping plate 211 on one side of the connecting rod 2 on the first ring 1. Wrap the symmetric annular clamping plates 211 around the first ring 1. Then, rotate the fixing rods 214 in the hole grooves 213 to connect and fix the symmetric annular clamping plates 211, so as to be stably fixed on the first ring 1.

The operation is simple and convenient. The grading ring is set as a power fitting that is convenient for assembly and disassembly, and is assembled on site after being transported to the site, reducing the packaging volume and the transportation cost.

[0023] Further, a mounting plate 12 is fixedly arranged on the first ring 1. The mounting plate 12 is used for installing and connecting power fittings. A plurality of holes are arranged on the mounting plate 12. After the grading ring is assembled, fixing tools are installed on the mounting plate 12 to fixedly install the grading ring at the position of the insulator.

[0024] Embodiment 2

[0025] As Figure 1 and Figure 2 shown, a kind of anti-interference high-voltage power fitting proposed by the present utility model. Compared with Embodiment 1, as another implementation manner of the present utility model, adhesive plates 3 are pasted on both the first ring 1 and the second ring 11. A bird repelling pad 31 is arranged on the adhesive plate 3. The end face of the bird repelling pad 31 is a spiked end. When preventing birds from interfering with the power fitting, the power fitting is protected from the damage of bird droppings through the arrangement of the bird repelling pad 31. First, an adhesive layer is arranged on the back of the adhesive plate 3. Through the adhesive layer, the adhesive plate 3 with the bird repelling pad 31 is adhered to the first ring 1 and the second ring 11.

[0026] Working principle: When using the anti-interference high-voltage power fitting, first, when it is convenient to assemble the power fitting, it is convenient to assemble the power fitting through the installation of the annular clamping plate 211. First, the annular clamping plate 211 on one side of the connecting rod 2 is clamped on the first ring 1. The symmetric annular clamping plates 211 are wrapped around the first ring 1. Then, the fixed rod 214 rotates in the hole groove 213 to connect and fix the symmetric annular clamping plates 211, so as to be stably fixed on the first ring 1. Then, the annular clamping plate 211 at the other end of the connecting rod 2 is fixed on the second ring 11 in the same steps, so as to connect the first ring 1 and the second ring 11. The operation is simple and convenient. The grading ring is set as a power fitting that is convenient to assemble and disassemble. It is assembled on site after being transported to the site, reducing the packaging volume and lowering the transportation cost.

[0027] Finally, the arrangement of the bird repelling pad 31 protects the power fitting from the damage of bird droppings. First, an adhesive layer is arranged on the back of the adhesive plate 3. Through the adhesive layer, the adhesive plate 3 with the bird repelling pad 31 is adhered to the first ring 1 and the second ring 11. When birds try to land on the spiked bird repelling pad 31, they will feel uncomfortable or scared, so they will avoid these areas, thereby reducing the chance of birds perching on the power fitting, protecting the power fitting from the damage of bird droppings and bird bodies, and further preventing power interruption or equipment damage caused by bird damage. The bird repelling pad 31 is installed on the first ring 1 and the second ring 11 through the adhesive plate 3 without opening holes, reducing the influence on the uniform power transmission of the grading ring.
