[0028] Example 1

[0029] like Figure 1-4 As shown, the present invention is a voltage-equalizing ring for adjusting electric field distribution, comprising a No. 1 ring body 1, an annular groove 2 is arranged on the top of the No. 1 ring body 1, and movable hinge seats 3 are arranged near both sides of the inner bottom surface of the annular groove 2, and a movable plate 4 is hinged on the top of each movable hinge seat 3, and an arc clamp 5 is arranged on the top of each movable plate 4, and a reinforcing column 6 is arranged on one side of each movable plate 4, and two installation openings 7 are arranged on one side of each arc clamp 5 near the other two sides, and screw rods 8 are arranged between the opposite sides of the inner sides of the four installation openings 7, and nuts 9 are arranged on the outer walls of the four screw rods 8, and a tilting rod 10 is arranged at the bottom of the No. 1 ring body 1, and four tilting rods 10 are arranged at the bottom of the No. 1 ring body 1 in a circular equidistant array, a No. 2 ring body 11 is arranged between the sides of the four No. 1 ring bodies 1, a No. 3 ring body 12 is arranged between the bottoms of the four tilting rods 10, and an adjusting moving component 13 is arranged on the top of the No. 3 ring body 12.

[0030] Example 2

[0031] like Figure 1-4 As shown, the adjustment moving assembly 13 includes an annular track 131, which is arranged at the top of the No. 3 ring body 12. The top of the annular track 131 is slidably connected with eight sliders 132. The top of the eight sliders 132 is provided with a No. 1 connecting rod 133, one side of the eight No. 1 connecting rods 133 is provided with a No. 2 connecting rod 134, and one side of the eight No. 2 connecting rods 134 is provided with a ball 135.

[0032] In this embodiment, the annular track 131 can facilitate the sliding adjustment and movement of the slider 132 thereon, the slider 132 can support the No. 1 connecting rod 133, the No. 1 connecting rod 133 can support the No. 2 connecting rod 134, the No. 2 connecting rod 134 can support the sphere 135, the No. 1 connecting rod 133 and the No. 2 connecting rod 134 can guide the distribution of electric field lines through geometric shapes, improve the uniformity of the electric field, and also have a certain shielding effect on the electric field, reducing the local field strength, which can also ensure that the position and angle of the sphere 135 are stable and maintain the electric field optimization effect. The sphere 135 has a uniform curvature radius, which can reduce the local electric field strength. Multiple spheres 135 are dispersedly arranged to form multiple low field strength areas to improve the overall electric field distribution.

[0033] Example 3

[0034] like Figure 1-4 As shown, a drainage port 136 is provided on the inner bottom surface of the annular track 131 , and a drainage groove 14 is provided on the inner bottom surface of the annular groove 2 .

[0035] In this embodiment, the drain port 136 can facilitate the drainage of water inside the annular track 131, and the provided drain groove 14 can allow the water inside the annular groove 2 to be drained, which can facilitate outdoor use.

[0036] Working principle:

[0037] When it is necessary to replace it, the movable plate 4 on the movable hinge seat 3 inside the annular groove 2 can be clamped and fixed on both sides of the insulator with the arc clamp 5. When the equalizing rings on both sides of the insulator are damaged, the screw rod 8 is passed through the installation port 7, and the nut 9 is screwed in to fix it. This makes it easy to replace and install when it is damaged, saving the consumption of resources. There is no need to replace all of them. A more uniform electric field distribution can be formed through the No. 1 ring body 1, the No. 2 ring body 11 and the No. 3 ring body 12. The distribution area of ​​the No. 1 connecting rod 133 can be controlled by the annular track 131 and the slider 132. 33 and the second connecting rod 134 can first guide the distribution of electric field lines through geometric shapes to improve the uniformity of the electric field. This can also make the electric field have a certain shielding effect and reduce the local field strength. It can also support the position and angle stability of the sphere 135 by itself to maintain the electric field optimization effect. The sphere 135 above has a uniform curvature radius, which can reduce the local electric field strength. Multiple spheres 135 are dispersedly arranged to form multiple low field strength areas, improve the overall electric field distribution, and adjust the density and position of the sphere 135 according to the electric field distribution requirements. This can effectively improve the electric field distribution and performance of the grading ring.
