[0002] In power transmission systems, distribution lines are a crucial link between power stations and users, and their stability and safety are crucial. However, under certain meteorological conditions, such as freezing winter weather or strong winds, distribution lines are prone to galloping. This galloping not only increases the difficulty of line maintenance but can also lead to serious safety issues such as conductor breakage, short circuits, and power outages, significantly impacting the economy and residents' lives.

[0003] Existing anti-galloping measures primarily rely on various anti-galloping devices, such as turbulent anti-galloping devices, detuned pendulums, centralized anti-vibration hammers, double-pendulum anti-galloping devices, and wire clamp rotary spacers. These anti-galloping devices are complex structures, consisting of multiple components and connecting hardware. Under harsh operating conditions, they are prone to accumulation of dirt and ice spikes, forming conductive channels or ice bridges, increasing the risk of flashover and ice flashover. Therefore, regular inspection and maintenance of the anti-galloping devices are required to ensure their proper operation. Furthermore, due to the wide coverage of distribution network lines, anti-galloping devices are often installed in hard-to-reach locations such as high mountains and deserts, greatly increasing the difficulty of maintenance. Frequent maintenance in these situations further increases maintenance costs. Utility Model Content

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] See also Figures 1 to 12 As shown, the utility model provides an anti-dance spacer, which includes a rod body 1, an umbrella skirt 2 and a wire clamp 3. The umbrella skirt 2 is arranged on the rod body 1, and the wire clamp 3 is arranged at the end of the rod body 1. The first surface 21 and the second surface 22 of the umbrella skirt 2 are both conical surfaces. The inclination direction of the first surface 21 and the second surface 22 is the same, and the taper of the second surface 22 is smaller than the taper of the first surface 21.

[0036] In the above technical solution, the rod body mainly plays the role of mechanical connection and insulation, connecting the conductors between phases through the rod body to avoid entanglement and dancing between the conductors; the shed is set on the rod body, and its main function is to improve the anti-dance spacer's ability to withstand voltage, prevent flashover, and increase the creepage distance, that is, the length of the insulation path between the live part and the grounded part; the first surface 21 and the second surface 22 of the shed 2 are both conical surfaces, and the taper of the second surface 22 is smaller than that of the first surface 21. The first surface 21 and the second surface 22 are inclined in the same direction, so that the second surface 22 of the insulator shed is concave inward, forming an aerodynamic shed through the above design. Due to the conical design of the shed, dirt and ice spikes are more easily removed by wind or rain even in harsh environments, reducing the accumulation of dirt and ice spikes on the shed surface, thereby improving the shed's self-cleaning ability. In addition, the aerodynamic shed design makes the anti-dance spacer have better wind resistance and stability in strong wind conditions, helping to disperse the impact of wind on the anti-dance spacer, thereby reducing the risk of damage to the anti-dance spacer due to wind. Compared with the existing anti-dance devices that require regular maintenance to ensure that they can continue to effectively suppress the dance of the distribution network lines, the anti-dance spacer proposed in the present invention forms an aerodynamic umbrella skirt by setting a first surface 21 and a second surface 22 with the same inclination direction and different tapers, so that the anti-dance spacer has good self-cleaning and wind resistance. Therefore, the anti-dance spacer does not require maintenance during its life cycle, thereby greatly reducing maintenance costs.

[0037] In one embodiment of the present invention, the taper of the first surface 21 is 5° to 8°.

[0038] In the above technical solution, the taper of the first surface 21 is set to 5° to 8°, which can reduce the probability of dirt particles adhering to the surface of the insulator. When rain or wind blows, the inclination of the first surface 21 can more effectively cause dirt and water to slide off, preventing dirt from forming a stable accumulation on the surface, thereby reducing the risk of flashover. At the same time, this taper design helps to disperse the impact of wind and reduce wind-induced vibration of the insulator, thereby improving the wind resistance and long-term operational reliability of the insulator. The conical surface design makes it more likely that moisture will flow along the conical surface of the first surface 21 even on rainy days, rather than forming a continuous water flow between the sheds, thereby preventing rainwater from forming a continuous water bridge. This also reduces the risk of surface flashover to a certain extent and improves the anti-rain and flashover performance of the insulator.

[0039] In one embodiment of the present invention, the taper of the second surface 22 is 2° to 3°.

[0040] In the above technical solution, the second surface 22 has a taper of 2° to 3°, which reduces the chance of contaminants adhering to the insulator surface. When rain or wind blows, the tilt of the second surface 22 more effectively encourages contaminants and moisture to slide off, preventing them from accumulating on the surface and thus reducing the risk of flashover. Furthermore, the 2° to 3° taper of the second surface 22 is a crucial component of the aerodynamic sheds. This taper helps disperse wind impact, reducing direct wind damage to the insulator and minimizing wind-induced vibration, thereby improving the insulator's wind resistance and long-term operational reliability. This tapered design ensures that even in rainy weather, water tends to flow along the tapered surface of the second surface 22 rather than forming a continuous stream between the sheds. This prevents rainwater from forming continuous water bridges, which in turn reduces the risk of surface flashover and improves the insulator's flashover resistance.

[0041] In one embodiment of the present invention, the edges of the shed 2 are rounded.

[0042] In the above technical solution, the rounded corner design of the shed edge helps to improve the electric field distribution around the composite insulator and reduce the concentration of the electric field at the edge, thereby reducing the risk of partial discharge. In a high-voltage environment, the electric field lines will concentrate at sharp edges, which is prone to corona discharge. The rounded edges can smooth the electric field lines and improve the electrical performance of the insulator. At the same time, in cold areas, ice spikes may form on the surface of the insulator. If the shed edge is designed with sharp corners, the ice spikes are more likely to form bridges at these corners, thereby reducing the insulation performance of the insulator. The rounded edges can reduce the possibility of such ice spike bridging and increase the ice flash voltage. In addition, the rounded edges can also help improve aerodynamic performance, reduce wind resistance, and make the insulator have better stability and wind resistance under strong wind conditions.

[0043] In one embodiment of the present invention, the fillet radius of the edge is 1.2 mm to 2 mm, which does not increase the processing cost of the fillet of the shed edge too much, and can also meet the design requirements for the electrical, self-cleaning and anti-icing performance of the shed edge.

[0044] In one embodiment of the present invention, the umbrella skirt 2 includes a first umbrella skirt and a second umbrella skirt, the diameter of the first umbrella skirt is larger than that of the second umbrella skirt, and the first umbrella skirt and the second umbrella skirt are arranged on the rod body 1 at intervals.

[0045] In the above technical solution, the alternating arrangement of large and small sheds improves the composite insulator's stability and wind resistance in strong winds. Furthermore, the alternating arrangement of large and small sheds disrupts the continuous conductive path formed by dirt and moisture on the insulator surface, thereby reducing the occurrence of flashover accidents. Furthermore, the alternating arrangement of large and small sheds prevents ice spikes from forming a continuous bridge path between the large sheds, thereby enhancing the insulator's insulation performance in freezing conditions. Furthermore, the design of non-uniform sheds helps optimize the electromagnetic field distribution around the insulator, reducing the density of electric field lines in the central portion of the insulator and effectively controlling the occurrence of flashover.

[0046] In one embodiment of the present invention, the rod body 1 further includes a connecting portion 11 . The connecting portion 11 is provided at an end of the rod body 1 , and the wire clamp 3 is connected to the rod body 1 via the connecting portion 11 .

[0047] In the above technical solution, connection portion 11 is used to connect wire clamp 3 or right-angle bracket 4 to rod body 1, ensuring a stable and secure connection between them. Connection portion 11 also features features such as reinforcing ribs, optimized geometry, or material selection to disperse stress transmitted from wire clamp 3 or right-angle bracket 4 to rod body 1, reducing stress concentration on connection portion 11 and preventing material fatigue or structural damage caused by prolonged vibration and wind loads, thereby improving the reliability and service life of the entire device.

[0048] In one embodiment of the present invention, the rod body 1 includes a first connecting portion 111 at the first end and a second connecting portion 112 at the second end, the first connecting portion 111 is provided with a first connecting hole 113, and the second connecting portion 112 is provided with a second connecting hole 114, the wire clamp 3 includes a first wire clamp 31 and a second wire clamp 32, the first wire clamp 31 is detachably connected to the first connecting hole 113, and the second wire clamp 32 is detachably connected to the second connecting hole 114.

[0049] In the above technical solution, a first connecting hole 113 and a second connecting hole 114 are provided on the first connecting portion 111 and the second connecting portion 112. The first wire clamp 31 is detachably connected to the first connecting hole 113, and the second wire clamp 32 is detachably connected to the second connecting hole 114 by bolts or pins, so that the connection between the connecting wire clamp 3 or the right-angle hanging plate 4 and the rod body 1 does not require complicated tools or techniques, which simplifies the on-site installation process and thus reduces construction costs and time.

[0050] In one embodiment of the present invention, the central axis of the first connecting hole 113 is perpendicular to the central axis of the second connecting hole 114, and the anti-dance spacer also includes a right-angle hanging plate 4, the first end of the right-angle hanging plate 4 is rotatably connected to the second wire clamp 32, and the second end of the right-angle hanging plate 4 is rotatably connected to the second connecting hole 114.

[0051] In the above technical solution, since the conductors in the distribution network are generally arranged in parallel, and the central axis of the first connection hole 113 and the central axis of the second connection hole 114 are perpendicular to each other, it is impossible to connect the conductors. Therefore, by providing a right-angle hanging plate 4 at one end of the rod body 1, the clamping directions of the first wire clamp 31 and the second wire clamp 32 are parallel, thereby ensuring that the anti-dancing spacer proposed by the utility model can better clamp the conductor. At the same time, the first end of the right-angle hanging plate 4 is rotatably connected to the second wire clamp 32, and the second end of the right-angle hanging plate 4 is rotatably connected to the second connection hole 114, so that the right-angle hanging plate 4 has a certain degree of freedom in the radial and axial directions of the conductor, so that the anti-dancing spacer can adapt to a certain degree of dancing of the conductor, thereby improving the adaptability and reliability of the device.

[0052] In one embodiment of the present invention, the wire clamp 3 includes a body 33 and a pressure cover 34, which are connected by bolts. A first groove 351 is provided on the body 33, and a second groove 352 is provided on the pressure cover 34. The first groove 351 and the second groove 352 are arranged opposite to each other and form a wire clamping hole 353.

[0053] In the above technical solution, the main body 33 is used to cooperate with the pressure cover 34 to clamp the distribution network line. At the same time, the main body 33 is connected to the connecting part 11 by bolts or pins, thereby realizing the connection between the wire clamp 3 and the rod body 1. The main body 33 and the pressure cover 34 are connected by bolts, which can quickly realize the buckling and fixation of the main body 33 and the pressure cover 34, reducing the difficulty of installing the wire clamp 3. The first groove 351 and the second groove 352 are used to accommodate cables. The first groove 351 and the second groove 352 are arranged opposite to each other. When the main body 33 and the pressure cover 34 are connected by bolts, the first groove 351 and the second groove 352 form a wire clamping hole 353. The wire clamping hole 353 plays a role in limiting and fixing the cable, thereby realizing the connection between the cable and the anti-dance spacer.

[0054] In one embodiment of the present invention, the clamping hole 353 is circular or polygonal. This allows the clamping hole 353 to fit more closely with the clamped cable, improving the clamping strength of the wire clamp 3 on the wire. It also prevents sharp edges from clamping the wire, protecting the wire and reducing the risk of damage to the wire's outer insulation layer.

[0055] In one embodiment of the present invention, a double nut is used in conjunction with a screw to secure the body 33 and the gland 34. A single nut can gradually loosen under prolonged vibration, potentially leading to failure of the connection between the wire clamp 3 and the conductor. However, the double nut design, through the preload and friction between the two nuts, effectively resists thread loosening, achieving self-locking and maintaining a long-term stable connection, even under conditions of continuous vibration.

[0056] In one embodiment of the present invention, a buffer pad 354 is disposed in the first groove 351 and the second groove 352 , and the buffer pad 354 is made of a flexible material.

[0057] In the above technical solution, buffer pad 354 is made of a flexible material such as rubber and is primarily used to provide a soft contact surface for the wire, reducing direct friction between the hard material and the wire and preventing abrasion of the insulation layer. Furthermore, buffer pad 354 can absorb the vibration energy generated by the dancing wire, reducing the relative vibration between the wire clamp and the wire, and reducing the mechanical stress and damage risk caused by vibration. Because the flexible material can undergo elastic deformation within a certain range, thereby adapting to slight changes in the wire outer diameter, buffer pad 354 can also improve the adaptability of wire clamp 3 to wires of different diameters and shapes to a certain extent.

[0058] In an embodiment of the present invention, a limiting groove 355 is further provided in the first groove 351 and the second groove 352 , and the protruding portion of the buffer pad 354 is provided in the limiting groove 355 .

[0059] In the above technical solution, the limiting groove 355 is mainly used to limit the buffer pad 354. By clamping the protrusion on the buffer pad 354 in the limiting groove 355, the buffer pad 354 is prevented from being displaced due to vibration during the dancing of the wire, thereby ensuring that the buffer pad 354 works normally at the correct position.

[0060] In one embodiment of the present invention, the shed 2 is integrally formed of a composite insulating material, such as high-temperature vulcanized silicone rubber, and both the first surface 21 and the second surface 22 are smooth surfaces.

[0061] In the above technical solution, the integrally molded composite insulation shed design ensures the structural integrity and mechanical strength of the insulator, improves the durability and reliability of the anti-dancing spacer, and enables it to maintain stable insulation performance even in high-voltage environments, effectively preventing flashover and the formation of conductive paths. High-temperature vulcanized silicone rubber exhibits excellent electrical insulation and weather resistance, capable of withstanding electric field and temperature fluctuations in severe weather conditions. It also maintains good electrical and mechanical strength even under harsh operating conditions, meeting the performance requirements of insulator materials. The smooth, edgeless first and second surfaces 21, 22 allow rain and wind to more effectively wash away surface dirt and ice, improving the insulator's self-cleaning properties.

[0062] The rod body 1 also includes a connecting portion 11, and the anti-dance spacer rod also includes a right-angle hanging plate 4. The wire clamp 3, the connecting portion 11 and the right-angle hanging plate 4 are all made of high-strength lightweight alloys, such as aluminum alloy, titanium alloy and magnesium alloy.

[0063] In the above technical solution, the high-strength lightweight alloy material has high mechanical strength and can withstand stress and loads in harsh environments, ensuring that the anti-dance spacer can maintain structural integrity and stability when encountering extreme conditions such as strong winds, ice and snow. In addition, the high-strength lightweight alloy material has a lower density than traditional steel, which can significantly reduce the weight of the entire device. This is especially important for distribution network lines, because the carrying capacity of distribution network lines is limited. Overweight equipment will bring additional burdens to the lines, affecting the normal operation of the lines and the sag of the conductors. High-strength lightweight alloy materials such as aluminum alloys, titanium alloys and magnesium alloys also have good corrosion resistance and can work stably for a long time in harsh environments such as humidity and saline-alkali, reducing the need for maintenance due to corrosion.

[0064] In one embodiment of the present invention, the first umbrella skirt and the second umbrella skirt are arranged on the rod body in a three-umbrella-five combination, a large and small umbrella, or a large and small umbrella.

[0065] In the above technical solution, the first and second sheds are arranged on the rod body in a three-shed-five arrangement, a large-small shed, or a large-small-small shed arrangement. This helps optimize the distribution of the electric field on the insulator shed surface, significantly improving the composite insulator's pollution and ice flashover protection. This arrangement, combined with the aerodynamic shed design, further reduces wind resistance, improves the composite insulator's stability and wind resistance in strong winds, and reduces wind damage and maintenance costs.

[0066] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the rod body mainly plays the role of mechanical connection and insulation, and the phase conductors are connected through the rod body to avoid entanglement and dancing between the conductors; the shed is arranged on the rod body, and its main function is to improve the ability of the anti-dancing spacer to withstand voltage, prevent flashover, and increase the creepage distance, that is, the length of the insulation path between the live part and the grounded part; the first surface 21 and the second surface 22 of the shed 2 are both conical surfaces, the taper of the second surface 22 is smaller than the first surface 21, and the inclination direction of the first surface 21 and the second surface 22 is the same, so that the second surface 22 of the insulator shed is concave inward, and an aerodynamic shed is formed by the above design. Due to the conical design of the umbrella skirt, dirt and ice spikes are more easily removed by wind or rain even in harsh environments, reducing the accumulation of dirt and ice spikes on the surface of the umbrella skirt, thereby improving the self-cleaning ability of the umbrella skirt. In addition, the design of the aerodynamic umbrella skirt enables the anti-dance spacer to have better wind resistance and stability under strong wind conditions, which helps to disperse the impact of wind on the anti-dance spacer, thereby reducing the risk of damage to the anti-dance spacer due to wind. Compared with the existing anti-dance devices that require regular maintenance to ensure their continued and effective suppression of distribution network line dance, the anti-dance spacer proposed in the present invention forms an aerodynamic umbrella skirt by setting a first surface 21 and a second surface 22 with the same inclination direction and different tapers, so that the anti-dance spacer has good self-cleaning and wind resistance. Therefore, the anti-dance spacer does not require maintenance during its life cycle, thereby greatly reducing maintenance costs.
