Description

Technical Field

[0001] The utility model belongs to the technical field of pressure equalizing rings, and in particular relates to a composite pressure equalizing ring. Background Art

[0002] The voltage grading ring is a ring-shaped hardware used to improve the voltage distribution of the insulator string. Its main function is voltage grading, which can evenly distribute the high voltage around the object to ensure that there is no potential difference between the various parts of the ring, thereby achieving the effect of voltage grading. The voltage grading ring is suitable for AC voltage and can be used in high-voltage electrical appliances, high-rise buildings and other fields.

[0003] A Chinese patent with application number CN202021334063.8 in the prior art discloses a composite equalizing ring, which relates to the field of power hardware technology, including an equalizing ring body, a bird-proofing device placement area is provided on the equalizing ring body, a bird-proofing device is installed on the bird-proofing device placement area, the bird-proofing device includes a fixed bracket and a bird-proofing device, the fixed bracket is provided with a tightening screw, the fixed bracket is an "I"-shaped bracket, the fixed bracket is provided with a threaded hole, and the tightening screw is passed through the threaded hole; the bird-proofing device includes a base, a bird-proofing needle is provided in the base, the bird-proofing needle is fixedly provided in the central part of the base, a ball head groove is staggered on the outer edge side of the base, a ball head is clamped in the ball head groove, and the bird-proofing needle is provided on the ball head, an external threaded portion is provided on the upper part of the base, a rotating cylinder is sleeved on the base, the interior of the rotating cylinder is hollow, and an internal threaded portion is provided at the bottom of the rotating cylinder.

[0004] The voltage-equalizing ring is installed at a higher position, so it is more laborious to fix and install. The more complex the structure is, the longer it takes for the staff to install it. It is inconvenient to install and disassemble. In addition, the birds' stay will cause stains to accumulate in the porcelain bottle, causing the insulation strength of the porcelain bottle surface to decrease, resulting in line tripping. For this reason, we propose a composite voltage-equalizing ring. Utility Model Content

[0023] Example

[0024] See also Figure 1-Figure 3 , the technical solution provided by this embodiment is as follows:

[0025] A composite pressure equalizing ring comprises a main ring body 1 and a secondary ring body 2, and is characterized in that an ear shaft 3 is provided at one end of the main ring body 1, one end of the secondary ring body 2 is rotatably connected in the ear shaft 3, a mounting portion 6 is provided at the center of the main ring body 1 and the secondary ring body 2, the main ring body 1 and the secondary ring body 2 are fixedly connected by bolts 8, and the tops of the main ring body 1 and the secondary ring body 2 are both detachably connected with triangular wind cups 11.

[0026] In a specific embodiment of the utility model, the main ring body 1 and the auxiliary ring body 2 are symmetrically designed to form a ring body together, so as to evenly distribute the high voltage around the object and ensure that there is no potential difference between the various parts of the ring, thereby achieving the effect of equalizing the voltage. The mounting portion 6 is used to fix the main ring body 1, and can be connected to metal parts such as metal doors and windows, metal railings, etc. The main ring body 1 and the auxiliary ring body 2 are both provided with positioning holes 7 on the side close to each other, and the bolt 8 is installed in the positioning hole 7. The position of the positioning hole 7 is far away from the ear axis 3. After the main ring body 1 and the auxiliary ring body 2 are fitted, the bolt 8 is passed through the positioning hole 7 and then tightened. The fixing method is simple and easy to operate. Compared with the existing assembly structure, the installation method is simpler and easy to carry. It is important to install a triangular wind cup 11 in the equipment hole 9. A total of two triangular wind cups 11 are set, and no electricity is required. A reflective lens is installed on the inner wall of the triangular wind cup 11. Based on the characteristics of birds being afraid of light, especially the fear of flashes, by reflecting light or emitting dazzling light, birds dare not approach, thereby achieving the purpose of driving away birds, protecting the ring body from birds staying, and extending the service life.

[0027] Specifically, the tops of the main ring body 1 and the auxiliary ring body 2 are both provided with equipment holes 9, a positioning rod 10 is arranged in the equipment hole 9, a triangular wind cup 11 is rotatably connected to the upper end of the positioning rod 10, and the lower end of the positioning rod 10 passes through the equipment hole 9 and is threadedly connected with a nut 12.

[0028] In the specific embodiment of the utility model, the positioning rod 10 and the nut 12 are both made of plastic material, which is an insulating material and will not affect the pressure-dividing effect of the ring body itself. The positioning rod 10 can be fixed by only passing it through the equipment hole 9 and then tightening the nut 12. The installation method is simple and time-saving.

[0029] Specifically, a clamping groove 4 is provided at the other end of the main ring body 1 , and a clamping block 5 is provided at the other end of the auxiliary ring body 2 , and the clamping block 5 is embedded in the clamping groove 4 .

[0030] In a specific embodiment of the utility model, the thickness of the block 5 is the same as the width of the slot 4. After installation, the block 5 can be seamlessly embedded in the slot 4, making it easier to align the positioning hole 7 during installation, thereby preventing the main ring body 1 and the auxiliary ring body 2 from deformation and extending the service life.

[0031] Working principle: After the main ring body 1 and the auxiliary ring body 2 are fitted together, the bolt 8 is passed through the positioning hole 7 and then tightened. The fixing method is simple. The triangular wind cup 11 is installed in the equipment hole 9. A total of two triangular wind cups 11 are set. No electricity is required. The inner wall of the triangular wind cup 11 is installed with a reflective lens. Based on the characteristics of birds being afraid of light, especially the fear of flashes, by reflecting light or emitting dazzling light, birds dare not approach, thereby achieving the purpose of driving away birds, protecting the ring body from birds staying, and extending the service life.
