Description

Technical Field

[0001] The invention belongs to the technical field of insulators, and more specifically, particularly relates to a transformer substation insulator. Background Art

[0002] Insulators are devices installed between conductors at different potentials or between conductors and grounded structures, which can withstand voltage and mechanical stress. There are many types of insulators with different shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting fittings. Insulators play an important role in substations. They can not only achieve electrical isolation and support and fixation, but also protect the safe operation of electrical equipment and ensure the safety of personnel. Therefore, insulators are indispensable in substations.

[0003] In order to prevent leakage and ensure better power transmission, insulators need to be connected to each other. When connecting existing insulators, multiple insulators need to be connected by hammering pins with the help of tools. However, insulator installation often involves high-altitude operations. When working at heights, carrying and using tools will increase the complexity of the operation, which not only increases the operation time, but may also affect the accuracy and efficiency of the operation, thereby affecting the maintenance of power equipment and the stability of power transmission. Installation, replacement and disassembly are inconvenient.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a substation insulator is provided to achieve a more practical purpose. Summary of the invention

[0014] Preferably, an inclined baffle is fixedly connected to the upper end of the support seat, and the inclined baffle is rotatably connected above the insulator body, and a second sliding rod is fixedly connected to a side of the second rotating rod close to the sliding block.

[0015] Preferably, a convex groove is provided inside the sliding block, and the second sliding rod is slidably connected inside the convex groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, a rotating disc is provided. When connecting multiple insulator bodies, the rotating handle is screwed to ensure that the clamping block is in a retracted state, and the hanging rings of the multiple insulator bodies are inserted into the connecting cap. At this time, the connecting cylinder in the retracted state is put into the connecting cap, and the rotating handle is screwed. The rotating handle drives the rotating disc to rotate through the round rod. During the rotation of the rotating disc, the first sliding rod slides in the arc groove to drive the clamping block to slide outward, so as to connect the multiple insulator bodies. Only the rotating handle needs to be screwed to drive the clamping block to slide for limiting and fixing. The operation is simple and there is no need to carry additional tools when working at high altitudes, which improves work efficiency, reduces the risks of operators when working at high altitudes, improves the convenience of connecting the insulator bodies, and facilitates replacement and maintenance work.

[0018] In the present invention, a cleaning brush is provided. When the insulator body needs to be cleaned after being used for a long time, the first rotating rod is screwed, and the first rotating rod drives the cleaning brush to rotate. The cleaning brush is installed between the two groups of insulator bodies. The surface of the insulator body is wiped and cleaned by the rotation of the cleaning brush, so that the surface of the insulator is kept clean to ensure its insulation performance and prevent the accumulated dirt from causing insulation failure or flashover, thereby improving the reliability and safety of the entire power system.

[0019] In the present invention, by providing a first gear, when the first rotating rod drives the cleaning brush to rotate for cleaning, the first rotating rod drives the first gear to rotate, and the first gear drives the two second gears to rotate through meshing, and the rotation of the second gear drives the first connecting pin to produce a rotation direction opposite to the first gear. The cleaning brush and the insulator body produce opposite rotation directions, thereby increasing their contact area, ensuring that the cleaning brush wipes evenly, thereby effectively cleaning the surface of the insulator body, reducing gaps that cannot be cleaned, and improving the comprehensiveness and efficiency of cleaning.

[0020] In the present invention, by providing an inclined baffle, during the daily operation of the insulator body, a sliding block can slide downward, and when the sliding block slides, it drives the second sliding rod to slide in the convex groove, and during the sliding of the convex groove, it drives the second rotating rod to rotate, and the second rotating rod drives the inclined baffle to rotate and rise through the support seat, and the insulator body is covered by the inclined baffle, so as to protect the insulator body from the influence of the external environment and climate (such as dust, dirt, rain, bird droppings, etc.) during daily work, extend the service life of the insulator body, improve the reliability and stability of the equipment, and the two inclined baffles are lifted and covered by pushing the sliding block to slide, and the covering action is completed quickly, thereby saving time and improving work efficiency.

[0021] In the present invention, a limit block is provided, and the sliding block slides in the rectangular slide groove. During the sliding process of the sliding block, the sliding block is limited by the rectangular slide groove to limit its sliding trajectory and ensure that the sliding block maintains a stable position during the sliding process. The sliding block squeezes the limit block inward when sliding. When the sliding block slides into place, the return spring drives the limit block to slide outward to limit the sliding block, so as to improve the stability and reliability of the inclined baffle during the shielding and protection process.

The second fixing plate 25 is connected to the first fixing plate 11 and the second fixing plate 25 and the substation equipment in the substation. The wire is fixed in the air or on other equipment through the insulator body 14 to ensure the stable operation of the power equipment, and the wire is isolated from the support (such as a transmission tower or substation equipment) to prevent the current from entering the ground or other equipment through the support, which plays the role of electrical insulation. When connecting multiple insulator bodies 14, the rotating handle 18 is screwed to ensure that the clamping block 22 is in a retracted state, and the hanging rings 13 of the multiple insulator bodies 14 are inserted into the connecting cap 15. At this time, the retracted The connecting cylinder 16 in the state is put into the connecting cap 15, and the rotating handle 18 is screwed. The rotating handle 18 drives the rotating disk 19 to rotate through the round rod 17. During the rotation of the rotating disk 19, the first sliding rod 23 slides in the arc groove 21 to drive the clamping block 22 to slide outward, so as to connect multiple insulator bodies 14. It only needs to screw the rotating handle 18 to drive the clamping block 22 to slide for limit fixing.

[0033] The first fixed plate 11 is internally rotatably connected with a first rotating rod 26, and a cleaning brush 27 is sleeved on one side of the first rotating rod 26 close to the second fixed plate 25. The cleaning brush 27 is rotatably connected to the center of the second fixed plate 25. A first gear 28 is sleeved on the outer surface of the first rotating rod 26, and a second gear 29 is sleeved on the outer surface of the first connecting pin 12. The first gear 28 and the second gear 29 are meshed with each other.

The cleaning brush 27 is installed between the two groups of insulator bodies 14. The surface of the insulator body 14 is wiped and cleaned by the rotation of the cleaning brush 27 to keep the surface of the insulator clean. The surface is kept clean to ensure its insulation performance and prevent accumulated dirt from causing insulation failure or flashover, thereby improving the reliability and safety of the entire power system.

The rotation of the second gear 29 drives the first connecting pin 12 to produce a rotation direction opposite to the first gear 28, and the cleaning brush 27 and the insulator body 14 produce opposite rotation directions, thereby increasing their contact area and ensuring that the cleaning brush 27 is wiped evenly, thereby effectively cleaning the surface of the insulator body 14, reducing gaps that cannot be cleaned, and improving the comprehensiveness and efficiency of cleaning.

[0034] A rectangular slot 31 is provided inside the first fixed plate 11, and a sliding block 32 is slidably connected inside the rectangular slot 31. A return spring 33 is fixedly connected to the inner wall of the rectangular slot 31. One end of the return spring 33 close to the sliding block 32 is fixedly connected to a limit block 34. The limit block 34 is slidably connected inside the rectangular slot 31. The rectangular slot 31 and the sliding block 32 are on the same horizontal line. A second rotating rod 35 is rotatably connected inside the first fixed plate 11, and a support seat 36 is fixedly connected to the upper end of the second rotating rod 35. The upper end of the support seat 36 is fixedly connected to a bevel baffle 37, which is rotatably connected to the top of the insulator body 14. The second rotating rod 35 is fixedly connected to the side of the sliding block 32 close to the second sliding rod 38. The sliding block 32 has a convex groove 39, and the second sliding rod 38 is slidably connected to the convex groove 39. When the insulator body 14 is working normally, the sliding block 32 can be slid downward, and the sliding block 32 drives the second sliding rod 38 to slide in the convex groove 39. The sliding process of the convex groove 39 The second rotating rod 35 is driven to rotate through the support seat 36, and the second rotating rod 35 drives the inclined baffle 37 to rotate and rise, and the insulator body 14 is covered by the inclined baffle 37 to protect the insulator body 14 from being affected by the external environment and climate (such as dust, dirt, rain, bird droppings, etc.) during daily work, thereby extending the service life of the insulator body 14 and improving the reliability and stability of the equipment. The two inclined baffles 37 are raised and shielded by pushing the sliding block 32 to slide, and the covering action is completed quickly, thereby saving time and improving work efficiency.

When the sliding block 32 slides, it squeezes the limit block 34 inwardly. When the sliding block 32 slides into place, the limit block 34 is driven by the reset spring 33 to slide outward to limit the sliding block 32, so as to improve the stability and reliability of the inclined baffle 37 in the shielding and protection process.

[0035] Working principle:

[0036] The first step is to connect the first fixing plate 11 and the second fixing plate 25 to the substation equipment in the substation, and fix the wire in the air or other equipment through the insulator body 14 to ensure the stable operation of the power equipment, and isolate the wire from the support (such as a transmission tower or substation equipment) to prevent the current from entering the ground or other equipment through the support, so as to play the role of electrical insulation. When connecting multiple insulator bodies 14, screw the rotating handle 18 to ensure that the clamping block 22 is in a retracted state, and put the hanging rings 13 of the multiple insulator bodies 14 into the connecting cap 15. At this time, the retracted The connecting cylinder 16 is placed in the connecting cap 15, and the rotating handle 18 is screwed. The rotating handle 18 drives the rotating disk 19 to rotate through the round rod 17. During the rotation of the rotating disk 19, the first sliding rod 23 slides in the arc groove 21 to drive the clamping block 22 to slide outward, so as to connect multiple insulator bodies 14. Only the rotating handle 18 needs to be screwed to drive the clamping block 22 to slide for limited fixing. The operation is simple and there is no need to carry additional tools when working at high altitudes, which improves work efficiency, reduces the risks of operators when working at high altitudes, improves the convenience of connecting the insulator body 14, and facilitates replacement and maintenance work.

[0037] In the second step, when the insulator body 14 needs to be cleaned after being used for a long time, the first rotating rod 26 is screwed, and the first rotating rod 26 drives the cleaning brush 27 to rotate. The cleaning brush 27 is installed between the two groups of insulator bodies 14. The surface of the insulator body 14 is wiped and cleaned by rotating the cleaning brush 27 to keep the surface of the insulator clean to ensure its insulation performance and prevent accumulated dirt from causing insulation failure or flashover, thereby improving the reliability and safety of the entire power system. When the first rotating rod 26 drives the cleaning brush 27 to rotate and clean, the first rotating rod 26 drives the first gear 28 to rotate, and the first gear 28 drives the two second gears 29 to rotate through meshing. The rotation of the second gear 29 drives the first connecting pin 12 to generate a rotation direction opposite to that of the first gear 28. The cleaning brush 27 and the insulator body 14 generate opposite rotation directions, increasing their contact area, ensuring that the cleaning brush 27 is wiped evenly, thereby effectively cleaning the surface of the insulator body 14, reducing gaps that cannot be cleaned, and improving the comprehensiveness and efficiency of cleaning.

[0038] In the third step, during the daily operation of the insulator body 14, the sliding block 32 can be slid downward. When the sliding block 32 slides, it drives the second sliding rod 38 to slide in the convex groove 39. During the sliding process of the convex groove 39, the second rotating rod 35 is driven to rotate. The second rotating rod 35 drives the inclined baffle 37 to rotate and rise through the support seat 36. The insulator body 14 is covered by the inclined baffle 37 to protect the insulator body 14 from the external environment and climate (such as dust, dirt, rain, bird droppings, etc.) during daily work, thereby extending the service life of the insulator body 14 and improving the reliability and stability of the equipment. The movable sliding block 32 slides to realize the raising of the two inclined baffles 37 for shielding, and the covering action is completed quickly, thereby saving time and improving work efficiency. The sliding block 32 slides in the rectangular slide groove 31. During the sliding process of the sliding block 32, it is limited by the rectangular slide groove 31 to limit its sliding trajectory and ensure that the sliding block 32 maintains a stable position during the sliding process. When the sliding block 32 slides, it squeezes the limit block 34 inwardly. When the sliding block 32 slides into place, the return spring 33 drives the limit block 34 to slide outward to limit the sliding block 32, so as to improve the stability and reliability of the inclined baffle 37 in the shielding and protection process.
