Description

Technical Field

[0001] The invention belongs to the technical field of voltage grading rings, and in particular relates to a voltage grading ring for an ultra-high voltage segmented synthetic insulator and a use method thereof. Background Art

[0002] The voltage grading ring is a ring-shaped protective hardware that improves the voltage distribution of the insulator string. Its main function is to prevent side lightning strikes. It is suitable for occasions where the voltage is AC. It 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.

[0003] The prior art discloses a Chinese patent with application number CN201510587863.8, which discloses a fixing structure of an ultra-high voltage power transmission and transformation equipment grading ring, including a fixing clamp, a bracket and an intermediate flange. A clamping cavity for clamping and fixing the grading ring is formed in the middle of the fixing clamp. One end of the bracket is connected to the fixing clamp, and the other end of the bracket is connected to the intermediate flange. The surface of the intermediate flange is provided with a flange mounting hole for fixing the intermediate flange on the power transmission and transformation equipment. The present invention has good structural identity and is easy to install. It replaces the simple welding of the bracket and the grading ring, increases the structural strength between the grading ring and the bracket, and thus improves the resistance of the grading ring to harsh climate environments.

[0004] The voltage-equalizing rings on the market are generally fixed by bolts. Since the voltage-equalizing rings are installed on the insulating pillars, and most of them are installed in the middle position of the insulating pillars, the installation and disassembly are very cumbersome. When the voltage-equalizing ring itself fails or needs to be replaced, the entire insulating pillar needs to be disassembled, which is time-consuming and labor-intensive. In addition, the voltage-equalizing rings on the insulating pillars are easily affected by high temperatures. Excessive temperature may cause the material properties of the voltage-equalizing rings to deteriorate, thereby affecting their electrical properties and mechanical strength. In addition, high temperature may cause material deformation and reduce the service life. For this reason, we propose a UHV segmented synthetic insulator voltage-equalizing ring and a method for using the same. Summary of the invention

[0016] As a preferred solution of the present invention, the heat dissipation mechanism includes a heat exchange box, a micro pump and a radiator, the heat exchange box is fixedly connected to the horizontal plate of the mounting seat, the side of the heat exchange box is provided with a micro pump and a reflux port, the radiator is fixedly connected to the surface of the heat exchange box, and the ends of the two insulating ring bodies are respectively provided with a liquid inlet and a liquid outlet, a first pipe is fixedly connected between the liquid inlet and the micro pump, and a second pipe is fixedly connected between the liquid outlet and the reflux port.

[0022] A method for using a UHV segmented composite insulator grading ring comprises the following steps:

[0023] S1. When installing, first fix the positioning seat to the upper end of the insulating pillar with bolts, then assemble the insulating ring, heat exchange box and photovoltaic panel on the mounting seat. After assembly, put the mounting seat on the surface of the positioning seat until the block is engaged in the limit part. Due to the obstruction of the boss part, the block cannot move up and down, and the quick installation is completed;

[0024] S2. When disassembly is required, the dial is rotated to drive the turntable to rotate. Under the limiting action of the second outer slide groove, a plurality of sliders are synchronously moved linearly in the first outer slide groove, and then a plurality of blocks are driven away from the limiting portion until the blocks are separated from the limiting portion. At this time, the mounting seat is moved upward, and the overall structure assembled by the mounting seat and the insulating ring body can be separated from the positioning seat, so that the rapid disassembly is completed and the entire structure can be replaced and maintained;

After flowing in the insulating ring body, it enters the second pipe through the liquid outlet, and finally returns to the heat exchange box from the reflux port. The heat on the surface of the insulating ring body is taken away by the circulation of the heat exchange liquid, and then the heat is quickly dissipated through the radiator, and the insulating ring body is continuously cooled to ensure stable operation of the insulating ring body.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. In this solution, during installation, the mounting seat is sleeved on the surface of the positioning seat until the block is stuck in the limit portion. At this time, the block cannot move upward due to the obstruction of the boss portion, thereby fixing the position of the mounting seat and realizing rapid installation of the insulating ring body. When disassembly is required, the dial block is driven to drive the turntable to rotate slightly. Under the dual limiting action of the second outer slide groove and the slider, several sliders expand outward synchronously, and then drive several blocks to move outward synchronously until the block is separated from the limit portion. At this time, the mounting seat can be directly separated from the positioning seat upward to realize rapid disassembly of the mounting seat and the insulating ring body. The overall structure is easy to assemble and disassemble, which greatly reduces the time for later replacement, and the positioning seat is installed on the insulating pillar and can be reused without causing waste of resources.

[0028] 2. In this scheme, the inside of the insulating ring body is hollow and heat exchange liquid can flow. The heat exchange liquid is pumped into the first pipeline through a micro pump, enters the insulating ring body through the liquid inlet, flows in the insulating ring body, enters the second pipeline through the liquid outlet, and finally returns to the heat exchange box from the reflux port. The heat on the surface of the insulating ring body is taken away by the circulation of the heat exchange liquid, and then quickly dissipated through the radiator, continuously cooling the insulating ring body to ensure stable operation of the insulating ring body, effectively preventing deformation of the insulating ring body in a high temperature environment, preventing the electrical performance and mechanical strength from being affected, ensuring stable operation of the insulating ring body, and extending the service life.

[0029] 3. This solution is designed with a directional label on the guide plate indicating the direction of the shift block. By shifting the shift block in the direction indicated by the directional label, several card blocks can be controlled to move outward synchronously, and then the mounting seat can be mechanically disassembled, which simplifies the cost of learning and use and reduces the possibility of human error.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0044] See also Figure 1-Figure 10 , the technical solution provided by this embodiment is as follows:

[0045] A grading ring for an ultra-high voltage segmented synthetic insulator comprises an insulating support 1, a positioning seat 2, a mounting seat 5, an insulating ring body 6, a buckle mechanism, and a heat dissipation mechanism, wherein: the positioning seat 2 is fixedly connected to the circumferential surface of the insulating support 1, and a boss portion 3 and a limit portion 4 are provided on the circumferential surface thereof, and the limit portion 4 is located on the lower side of the boss portion 3; the mounting seat 5 is detachably connected to the surface of the positioning seat 2; two insulating ring bodies 6 are provided and are respectively located on the upper and lower sides of the mounting seat 5, which are fixed to the mounting seat 5 by a reinforcement frame 18, and the interiors thereof are all hollow structures; the buckle mechanism is provided on the mounting seat 5, and is used to fix the mounting seat 5 on the surface of the positioning seat 2; the heat dissipation mechanism is placed on the mounting seat 5, and it dissipates heat from the insulating ring body 6 by circulating a heat exchange fluid into the insulating ring body 6.

[0046] In a specific embodiment of the present invention, the insulating support 1 is composed of a plurality of segmented insulators, the positioning seat 2 is fixed to the upper end of the insulating support 1 by bolts, the hollow structure inside the insulating ring body 6 is respectively located on the upper and lower sides of the positioning seat 2, the reinforcement frame 18 is welded to the lower side of the insulating ring body 6, and the hollow structure at the center of the mounting seat 5 can be sleeved on the surface of the positioning seat 2, the boss portion 3 gradually increases in diameter from top to bottom, and the limiting portion 4 has a smaller diameter than the boss portion 3. During installation, the mounting seat 5 is sleeved on the surface of the positioning seat 2 until the block 8 is inserted into the limiting portion 4. At this time, under the obstruction of the boss portion 3, the block 8 cannot move upward, thereby fixing the position of the mounting seat 5 and realizing rapid installation of the insulating ring body 6. When disassembly is required, the dial block 14 is driven to drive the turntable 12 to rotate slightly. Under the dual limiting action of the second outer slide groove 13 and the slider 11, the plurality of sliders 11 expand outward synchronously, thereby driving the plurality of blocks 8 to move outward synchronously until the block 8 is separated from the limiting portion 4. At this time, the upward movement can be directly The mounting base 5 is then separated from the positioning base 2 to achieve quick disassembly of the mounting base 5 and the insulating ring body 6. The overall structure is easy to assemble and disassemble, which greatly reduces the time for later replacement. The positioning base 2 is installed on the insulating pillar 1 and can be reused without causing waste of resources. What is important is that the insulating ring body 6 of the present scheme is hollow inside and can allow heat exchange liquid to flow. The heat exchange liquid is pumped into the first pipe 25 through the micro pump 23, and the heat exchange liquid enters the insulating ring body 6 through the liquid inlet 20. After flowing in the insulating ring body 6, it enters the second pipe 26 through the liquid outlet 21, and finally returns to the heat exchange box 22 from the reflux port 24. The heat on the surface of the insulating ring body 6 is taken away by the circulation of the heat exchange liquid, and then the heat is quickly dissipated through the radiator 27, and the insulating ring body 6 is continuously cooled to ensure that the insulating ring body 6 works stably. It can effectively prevent the insulating ring body 6 from deforming in a high temperature environment, prevent the electrical performance and mechanical strength from being affected, ensure the stable operation of the insulating ring body 6, and extend the service life.

[0047] Specifically, the buckle mechanism includes a clamping block 8 and a turntable 12. The mounting seat 5 is provided with an inner slide groove 7 near the clamping block 8. The clamping block 8 is slidably connected to the inner slide groove 7. A spring 9 is fixedly connected between the clamping block 8 and the inner wall of the inner slide groove 7. A slider 11 is fixedly connected to the top of the clamping block 8. The turntable 12 is rotatably connected to the upper side of the mounting seat 5. A plurality of second outer slide grooves 13 are provided on the upper side of the turntable 12. A plurality of first outer slide grooves 10 are provided on the mounting seat 5. The clamping block 8 is provided with a plurality of sliders 11. Each slider 11 is slidably connected to the corresponding first outer slide groove 10 and second outer slide groove 13. The side of the clamping block 8 close to the positioning seat 2 is a slope structure, and the limiting portion 4 close to the clamping block 8 is a groove structure.

[0048] In a specific embodiment of the present invention, the block 8 is an inclined surface close to the positioning seat 2. When installing, the mounting seat 5 is sleeved on the surface of the positioning seat 2 from top to bottom. The block 8 can transition from the boss portion 3 to the limiting portion 4, and then under the elastic action of the spring 9, the block 8 is inserted into the limiting portion 4. Under the obstruction of the boss portion 3, the block 8 cannot move. Several blocks 8 are designed and evenly distributed around the positioning seat 2, and then the positions of the mounting seat 5 and the insulating ring body 6 are quickly fixed. The first outer slide groove 10 and the second outer slide groove 13 both play a limiting role. The first outer slide groove 10 is used to limit the linear movement of the slider 11. The second outer slot 13 can rotate with the turntable 12. When the turntable 12 rotates, the position of the second outer slot 13 gradually changes. The slider 11 moves linearly in the slider 11 as the position of the second outer slot 13 changes. The slider 11 and the second outer slot 13 are evenly distributed, so that a plurality of sliders 11 expand outward or contract inward synchronously. When contracting synchronously, the block 8 is inserted into the limit portion 4 to play a fixing role. When the block 8 expands synchronously until it is separated from the limit portion 4, the mounting seat 5 can be directly separated from the positioning seat 2. The mounting structure is stable, and the disassembly is simple and easy to operate, which reduces the workload.

[0049] Specifically, the heat dissipation mechanism includes a heat exchange box 22, a micro pump 23 and a radiator 27. The heat exchange box 22 is fixedly connected to the horizontal plate of the mounting base 5. The micro pump 23 and the reflux port 24 are arranged on the side of the heat exchange box 22. The radiator 27 is fixedly connected to the surface of the heat exchange box 22. The ends of the two insulating ring bodies 6 are respectively provided with a liquid inlet 20 and a liquid outlet 21. A first pipe 25 is fixedly connected between the liquid inlet 20 and the micro pump 23, and a second pipe 26 is fixedly connected between the liquid outlet 21 and the reflux port 24.

[0050] In a specific embodiment of the present invention, the heat exchange liquid is stored in the heat exchange box 22, and the micro pump 23 is a micro liquid pump with a small size and does not occupy space. When in use, the heat exchange liquid is pumped into the first pipe 25 through the micro pump 23, and then enters the insulating ring body 6 through the liquid inlet 20. After flowing in the insulating ring body 6, it enters the second pipe 26 through the liquid outlet 21, and finally returns to the heat exchange box 22 through the reflux port 24. During the flow in the insulating ring body 6, heat is exchanged on the surface of the insulating ring body 6. In an extremely high temperature environment, even if the insulating ring body 6 itself does not generate a large amount of heat, it may be affected by the increase in ambient temperature. Excessive temperature The degree may cause the material performance of the insulating ring body 6 to decline, thereby affecting its electrical performance and mechanical strength. The insulating ring body 6 is made of metal, and the thermal expansion coefficient of the metal material exists. When the temperature rises, the insulating ring body 6 may undergo a slight deformation. Although this deformation is usually very small, in some precision electrical systems, even a slight deformation may cause performance degradation or failure. The radiator 27 is installed on the surface of the heat exchange box 22, which can quickly dissipate the heat of the heat exchange liquid. The circulating heat exchange liquid can continuously dissipate the heat of the insulating ring body 6, thereby ensuring that the insulating ring body 6 maintains a stable working state and prolongs its service life.

[0051] Specifically, a shift block 14 is fixedly connected to the edge of the rotating disk 12 .

[0052] In a specific embodiment of the present invention, the shift block 14 is located on the outer side of the mounting seat 5. The shift block 14 can rotate the turntable 12, so that the plurality of second outer slide grooves 13 rotate along with the turntable 12, and finally control the movement of the card block 8, thereby playing a role in assisting the extension and retraction of the card block 8. The structure is simple and easy to operate.

[0053] Specifically, a guide plate 16 is fixedly connected to the top of the mounting seat 5 , and the guide plate 16 is located on the upper side of the turntable 12 .

[0054] In a specific embodiment of the present invention, a directional label indicating the direction in which the shift block 14 is shifted is designed on the guide plate 16. By shifting the shift block 14 in the direction indicated by the white label, a plurality of card blocks 8 can be controlled to move outward synchronously, and then the mounting base 5 can be mechanically disassembled, thereby simplifying the cost of learning and using and reducing the possibility of human error.

[0055] Specifically, a battery 28 is fixedly connected to the transverse plate of the mounting base 5 , and the micro pump 23 is electrically connected to the battery 28 .

[0056] In a specific embodiment of the present invention, the battery 28 is used to power the micro pump 23. Preferably, a thermometer can be designed on the insulating ring body 6. When the temperature of the insulating ring body 6 reaches a threshold, the micro pump 23 is started to circulate the heat exchange fluid. If the threshold is not reached, the micro pump 23 stops working to reduce power waste.

[0057] Specifically, an oblique bracket 30 is fixedly connected to the horizontal plate of the mounting seat 5 , and a photovoltaic panel 29 is fixedly connected to the end of the oblique bracket 30 . The photovoltaic panel 29 is electrically connected to the battery 28 .

[0058] In a specific embodiment of the present invention, supported by the inclined bracket 30, the photovoltaic panel 29 is in an inclined state, has a better illumination angle, improves power generation efficiency, and charges the battery 28 without additional wiring.

[0059] A method for using a UHV segmented composite insulator grading ring comprises the following steps:

[0060] S1. During installation, first fix the positioning seat 2 to the upper end of the insulating support 1 by bolts, then assemble the insulating ring 6, the heat exchange box 22 and the photovoltaic panel 29 on the mounting seat 5. After assembly, the mounting seat 5 is sleeved on the surface of the positioning seat 2 until the block 8 is engaged in the limiting portion 4. Due to the obstruction of the boss portion 3, the block 8 cannot move up and down, and the quick installation is completed;

[0061] S2. When disassembly is required, the rotating block 14 drives the rotating disk 12 to rotate. Under the limiting action of the second outer slide groove 13, the plurality of sliders 11 synchronously move linearly in the first outer slide groove 10, and then drive the plurality of clamping blocks 8 away from the limiting portion 4 until the clamping blocks 8 are out of the position of the limiting portion 4. At this time, the mounting seat 5 is moved upward, and the overall structure assembled by the mounting seat 5 and the insulating ring body 6 can be separated from the positioning seat 2, completing the rapid disassembly, and the entire structure can be replaced and maintained;

[0062] S3. When the temperature needs to be controlled, the heat exchange liquid is pumped into the first pipe 25 through the micro pump 23, and the heat exchange liquid enters the insulating ring body 6 through the liquid inlet 20. After flowing in the insulating ring body 6, the heat exchange liquid enters the second pipe 26 through the liquid outlet 21, and finally returns to the heat exchange box 22 from the reflux port 24. The heat on the surface of the insulating ring body 6 is taken away by the circulation of the heat exchange liquid, and then the heat is quickly dissipated through the radiator 27, so as to continuously cool the insulating ring body 6 and ensure the stable operation of the insulating ring body 6.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.

The heat on the surface of the insulating ring body (6) is taken away by the circulation of the heat exchange liquid, and then the heat is quickly dissipated through the radiator (27), so that the insulating ring body (6) is continuously cooled to ensure stable operation of the insulating ring body (6).
