Abstract
Description
Technical Field
[0001] This application relates to the technical field of porcelain insulators, and in particular to an anti-aging cylindrical porcelain insulator. Background Technology
[0002] Porcelain insulators are a key electrical component in power systems used to support transmission lines and prevent current leakage to the ground or other conductors. They are widely installed in various equipment requiring insulation or in overhead transmission lines.
[0003] In related technologies, porcelain insulators include a body and multiple skirts, with the multiple skirts disposed on the body.
[0004] In cold and humid regions, especially when the ambient temperature fluctuates near freezing point and is accompanied by freezing rain, sleet, or dense fog, the surface of the insulator is prone to icing, forming icicles. When the icicles are eccentric or unevenly distributed, the excessively large uneven icicles will generate a severe eccentric load. Since the body is a rigid material with low bending strength, brittle fracture may occur at the joints of the insulator body, affecting the service life of the porcelain insulator. Summary of the Invention
[0005] To address the problem of severe eccentric loads caused by excessively large, uneven ice crystals, this application provides an anti-aging cylindrical ceramic insulator.
[0006] This application provides an anti-aging cylindrical porcelain insulator, which adopts the following technical solution: An anti-aging cylindrical porcelain insulator includes a body and multiple skirts. The body includes a connecting part and a supporting part. The connecting part is disposed on the supporting part, and the multiple skirts are disposed on the supporting part. The connecting part is flexible, and both the connecting part and the supporting part are conductive. When one side of the skirt is iced, the connecting part bends. When one side of the skirt is iced to a certain extent, the connecting part drives the supporting part to return to its original position.
[0007] By adopting the above technical solution, when one side of the insulator skirt freezes, the flexible connection part can bend, and the weight of the icicle is converted into elastic strain energy of the connection part. As the icicle continues to freeze until it has a certain thickness, the icicle causes the connection part to bend to a certain angle, allowing the connection part to accumulate a large elastic potential energy. The elastic potential energy of the connection part overcomes the adhesion of the icicle, allowing the support part to quickly reset. During the reset process, the icicle shakes, allowing it to detach from the insulator skirt and fall, thus achieving the separation of the icicle from the insulator skirt. At the same time, it reduces the aging rate of the insulator skirt and extends the service life of the insulator.
[0008] Optionally, the umbrella skirt has a threaded groove on its surface away from the connecting part, and a through hole communicating with the threaded groove is formed on the side of the umbrella skirt, with water passing through both the through hole and the threaded groove.
[0009] By adopting the above technical solution, water flows along the groove wall of the threaded groove and can flow out from the perforation, so that water does not flow continuously to one side, reducing the possibility of ice accumulation on the same side of the umbrella skirt.
[0010] Optionally, the umbrella skirt is provided with a protective cover, and the surface of the protective cover away from the connecting part is provided with a guide strip. The guide strip is provided with a guide slope, and the distance between the guide slope and the ground gradually increases along the direction from the umbrella skirt to the support part.
[0011] By adopting the above technical solution, the guide strip is set on the surface of the protective sleeve away from the connecting part. When the icicle falls, the icicle can first hit the guide strip and slide along the guide slope to reduce the damage to the umbrella skirt caused by the icicle directly colliding with it, so that the protective sleeve can protect the umbrella skirt. At the same time, the icicle freezes on the protective sleeve to reduce the damage to the umbrella skirt caused by the icicle shaking and falling off.
[0012] Optionally, the umbrella skirt has a mounting groove on its surface near the ground, and the protective sleeve has a mounting ring for inserting into the mounting groove.
[0013] By adopting the above technical solution, the protective cover can be stably installed on the umbrella skirt by inserting the mounting ring into the mounting groove, so as to facilitate the replacement of the protective cover and allow the guide strip to stably protect the umbrella skirt.
[0014] Optionally, the connecting part includes a connecting strip and a limiting ring. The connecting strip is disposed on the supporting part, and the limiting ring is sleeved on the connecting strip. Both the connecting strip and the limiting ring are elastic.
[0015] By adopting the above technical solution, the connecting strip is set on the support part. Since the connecting strip itself is relatively thin, it is easy for the connecting strip to bend and deform. The limiting ring is sleeved on the connecting strip, so that the limiting ring can support the connecting strip and protect it, reducing the damage to the connecting strip.
[0016] Optionally, the limiting ring is provided with a receiving groove, and a receiving ring is provided in the receiving groove. The receiving ring is sleeved on the connecting strip. When the connecting strip abuts against the receiving ring, the connecting strip can drive the support part to reset.
[0017] By adopting the above technical solution, when the connecting strip undergoes bending deformation, the receiving ring is sleeved on the connecting strip, allowing the connecting strip to abut against the receiving ring, preventing excessive deformation of the connecting strip, and the limiting ring can support the support part, so as to realize the reset of the support part.
[0018] Optionally, a limiting inclined surface is formed on the surface of the limiting ring near the umbrella skirt, and the distance between the limiting inclined surface and the umbrella skirt gradually decreases along the direction from the connecting strip to the limiting ring; when the body is in a vertical state, the limiting inclined surface abuts against the support part.
[0019] By adopting the above technical solution, the surface of the limiting ring near the umbrella skirt is used as a limiting slope. When the support part tilts, the support part presses against the limiting slope, so that the force of the limiting slope on the support part increases with the increase of the tilt angle of the support part, thereby allowing the limiting ring to stably drive the support part to return to its original position.
[0020] Optionally, the limiting ring has a through hole, the support part has a positioning groove, and the limiting ring has a positioning block for inserting into the positioning groove; when the positioning block is inserted into the positioning groove, the limiting ring is sleeved on the connecting strip.
[0021] By adopting the above technical solution, since the limiting ring has a through hole, the worker can directly put the limiting ring on the connecting strip, so that the limiting ring can be installed without removing the connecting strip. The limiting ring can be fixed on the connecting strip by inserting the positioning block into the positioning groove.
[0022] In summary, this application includes at least one of the following beneficial technical effects: When one side of the insulator skirt freezes, the flexible connection allows it to bend. The weight of the icicle is converted into elastic strain energy in the connection. As the icicle continues to freeze until it reaches a certain thickness, it causes the connection to bend at a certain angle, accumulating significant elastic potential energy. This elastic potential energy overcomes the adhesion of the icicle, allowing the support to quickly reset. During this reset process, the icicle sways, detaching from the insulator skirt and falling off, thus separating the icicle from the skirt. This also reduces the aging rate of the insulator skirt and extends the service life of the insulator.
[0023] By setting guide strips on the surface of the protective sleeve away from the connecting part, when icicles fall, they can first hit the guide strips and slide along the guide slope, thereby reducing the damage to the umbrella skirt caused by direct collision of the icicles with the umbrella skirt, and allowing the protective sleeve to protect the umbrella skirt.

[0026] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0027] This embodiment discloses an anti-aging cylindrical porcelain insulator. (Refer to...) Figure 1 An anti-aging cylindrical porcelain insulator includes a body 1 and multiple skirts 2. The body 1 includes a connecting part 12 and a supporting part 11, with the connecting part 12 disposed on one end of the supporting part 11.
[0028] Reference Figure 1 and Figure 2 Multiple umbrella skirts 2 are fixedly connected to the support 11, and the multiple umbrella skirts 2 are arranged in an array along the height direction of the support 11. The umbrella skirts 2 are inclined on the surface away from the ground, and the distance between the umbrella skirts 2 and the ground gradually increases along the direction from the umbrella skirts 2 to the support 11. Threaded grooves 21 are formed on the surface of the umbrella skirts 2 away from the ground, and multiple through holes 22 are formed on the side of the umbrella skirts 2, which are connected to the threaded grooves 21. Water is supplied through both the threaded grooves 21 and the multiple through holes 22.
[0029] Reference Figure 1 and Figure 3 The umbrella skirt 2 is equipped with a protective sleeve 23. Multiple guide strips 231 are fixedly connected to the surface of the protective sleeve 23 away from the ground. These guide strips 231 are arranged in a circumferential array along the protective sleeve 23, and are staggered with the perforations 22. A guide ramp 232 is formed on the surface of the guide strips 231 away from the ground. The distance between the guide ramp 232 and the ground gradually increases from the umbrella skirt 2 to the support 11. The guide ramp 232 is located on the path of falling ice, allowing the ice to fall onto the guide ramp 232, thus reducing damage to the umbrella skirt 2.
[0030] Reference Figure 3A mounting ring 233 is fixedly connected to the protective sleeve 23, and the mounting ring 233 extends circumferentially along the protective sleeve 23. A mounting groove 234 is provided on the ground-facing surface of the umbrella skirt 2 for inserting the mounting ring 233, and the mounting groove 234 extends circumferentially along the umbrella skirt 2. When the mounting ring 233 is inserted into the mounting groove 234, the protective sleeve 23 can be fixed to the umbrella skirt 2.
[0031] Reference Figure 4 The connecting part 12 includes a connecting strip 121 and a limiting ring 122. The limiting ring 122 is sleeved on the connecting strip 121. The connecting strip 121 is elastic and conductive, while the limiting ring 122 is elastic and insulating. A through hole 13 is provided on the limiting ring 122, through which the connecting strip 121 passes. One end of the connecting strip 121 is fixedly connected to the support part 11. A limiting inclined surface 131 is provided on the surface of the limiting ring 122 near the support part 11, and the limiting inclined surface 131 extends circumferentially along the limiting ring 122. The distance between the limiting inclined surface 131 and the ground gradually decreases along the direction from the limiting ring 122 to the connecting strip 121. When the support part 11 is tilted, the support part 11 can press against the limiting inclined surface 131, causing the limiting ring 122 to deform, so that the force of the support part 11 is distributed between the limiting ring 122 and the connecting strip 121.
[0032] Reference Figure 4 A receiving groove 132 is formed on the surface of the limiting ring 122, and a receiving ring 133 is fixedly connected in the receiving groove 132. The receiving ring 133 is sleeved on the connecting strip 121, and the receiving ring 133 does not abut against the support part 11. When the support part 11 is tilted, the connecting strip 121 undergoes bending deformation. At this time, the connecting strip 121 abuts against the receiving ring 133, and the receiving ring 133 restricts the connecting strip 121 from continuing to deform, thereby reducing the possibility that the connecting strip 121 may bend due to excessive force.
[0033] Reference Figure 4 A plurality of positioning blocks 14 are fixedly connected to the end face of the limiting ring 122 near the support portion 11, and the plurality of positioning blocks 14 are distributed in a circumferential array along the limiting ring 122. A plurality of positioning grooves 141 are formed on the end face of the support portion 11 for the positioning blocks 14 to be inserted, and the plurality of positioning grooves 141 are distributed in a circumferential array along the support portion 11. When the positioning block 14 is inserted into the positioning groove 141, the limiting ring 122 is fixedly connected to the support portion 11.
[0034] The implementation principle of an anti-aging cylindrical porcelain insulator according to an embodiment of this application is as follows: When one side of the umbrella skirt 2 is icy, the umbrella skirt 2 will tilt due to uneven force, causing the support part 11 to tilt and the connecting part 12 to bend and deform. Until the weight of the ice reaches a certain level, the elastic potential energy accumulated in the limiting ring 122 and the connecting strip 121 is greater than the weight of the ice, allowing the connecting part 12 to automatically reset, thereby restoring the umbrella skirt 2 and breaking the ice.
