Description

Technical Field

[0001] The present invention relates to the technical field of insulators, in particular to an anti-fouling suspended tempered glass insulator. Background Art

[0002] Suspension tempered glass insulators are vital components in power transmission systems. Their main functions are to provide electrical insulation and mechanical support to ensure the safe and stable operation of high-voltage transmission lines. Their electrical insulation effectively isolates the conductors from the supporting towers or the ground to prevent current leakage; their mechanical support ensures the stable suspension of the conductors by bearing their own weight and external loads (such as wind, ice and snow). In addition, suspension tempered glass insulators have excellent anti-pollution capabilities, can reduce dirt accumulation through their smooth surface characteristics, and maintain stable insulation performance with the help of the self-cleaning effect of rainwater; structurally, suspension tempered glass insulators consist of a tempered glass cover, metal rings, terminals and connectors. The tempered glass cover not only provides insulation, but also has strong tensile strength and impact resistance, while the metal parts ensure the stability of mechanical connection and electrical conduction. For example, an aerodynamic anti-pollution type suspension insulator disclosed in the authorization announcement number CN106298105B is composed of a steel cap, an umbrella skirt and a steel foot. The umbrella skirt is composed of an upper umbrella skirt and a lower umbrella skirt, and the radius of the upper umbrella skirt is larger than that of the lower umbrella skirt. A small annular umbrella ridge facing downward is provided at the outer edge of the upper umbrella skirt, which is not easy to deposit sand and dust on the surface of the insulator in a windy and sandy environment, thereby reducing the degree of pollution of the insulator; the large and small umbrellas cooperate with the small umbrella ridges to prevent bird pollutants, ice and rainwater from bridging, thereby improving the pollution flashover resistance of the insulator. The existing suspension insulator technology and use methods are basically the same, that is, when current passes through the conductor, the insulator can effectively prevent current leakage, and the glass insulator has good electrical properties. Even under wet or polluted conditions, its electrical The gas insulation can also remain stable. However, when multiple suspended insulators are currently used in series, the top insulator is connected to the angle steel crossarm using a right-angle hanging plate, while the bottom insulator uses a tension clamp to support the cable that needs to be insulated. The installation steps of the tension clamp are relatively complicated and usually require multiple processes for precise docking. During this process, the stability and safety of each connection part need to be ensured, and operators often need to work at high altitudes or in complex environments, which increases the difficulty of the work and potential safety risks. At the same time, the connection part of the tension clamp and the assembly process of the same cable are also relatively cumbersome. It is necessary to ensure that the connection between the insulator and the power conductor is stable and reliable, otherwise it may cause unstable operation of the power system, and even current leakage, system failure and other problems.

[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] Embodiment 1, by Figures 1 to 5 The present invention includes a tempered glass insulating disk 1 and a steel cap 2 fixed at the center of the top of the tempered glass insulating disk 1. A steel foot 3 for engaging with the steel cap 2 is installed at the center of the bottom of the tempered glass insulating disk 1; a suspension seat 7 is provided at the bottom of the steel foot 3, and a square column connector 4 for detachably connecting to the steel foot 3 is provided at the top of the suspension seat 7; a self-seepage cable support structure 8 for supporting the cable is provided at the bottom of the suspension seat 7; A mountain seat 9 is provided on one side outer wall of the suspension support 7. A bolting structure is provided between the suspension support 7 and the mountain seat 9. A double-spring cable pressure structure 10 is installed inside the mountain seat 9, which automatically adjusts the downward pressure according to the cable diameter in the self-seepage cable support structure 8. The mountain seat 9 is fixed to the outer wall of the suspension support 7 by the bolting structure. After the suspension support 7 and the mountain seat 9 are connected, the double-spring cable pressure structure 10 applies sufficient downward pressure on the power cable to ensure that the cable can be firmly fixed in the suspension support 7 and ensure that the cable will not slide or loosen due to external force or vibration. The steel cap 2 of the top insulator connected in series is connected to the angle steel cross arm through a ball head hanging ring and a right angle hanging plate. An opening for the steel leg 3 to enter is provided on one side of the surface of the steel cap 2, and a through groove is provided on the back of the steel cap 2 opposite to the opening. When multiple insulators are connected in series, the upper and lower adjacent insulators are clamped together by the steel cap 2 and the steel leg 3. That is, an opening is provided on the steel cap 2 to be clamped with the steel leg 3. Through such an opening, the two glass insulators can be clamped and connected. After the clamping, in order to prevent the two glass insulators from detaching, a through groove is provided on the steel cap 2 opposite to the opening. The steel leg 3 is locked by pushing the locking pin in the through groove. In actual operation, a special assembly device is used to push this locking pin. The locking operation is completed by moving the pushing head fixedly connected to one end of the pushing column toward the locking pin and contacting and knocking with the locking pin.

[0019] Example 2, based on Example 1, Figure 6 、 Figure 7 and Figure 8 The square column connector 4 includes a square-mouthed connecting column 401 for plugging into the steel leg 3, a sinking hole 402 provided at the top of the square-mouthed connecting column 401 for plugging into the steel leg 3, and a positioning pin 403 installed inside the square-mouthed connecting column 401. A through hole is provided at one end of the surface of the steel leg 3. The through hole is used to maintain a concentric state with the positioning pin 403 after the steel leg 3 and the square column connector 4 are plugged in. The bottom end of the square-mouthed connecting column 401 is movably connected to the top end of the suspension bracket 7. When the suspension bracket 7 is connected to the steel foot 3 through the square column connector 4, the staff makes the square column connector 4 plug into the steel foot 3 through the sinking hole 402 until the through hole at one end of the surface of the steel foot 3 is concentric with the positioning pin 403, and then inserts the positioning pin 403 from the square column connector 4 into the through hole of the steel foot 3 until one end of the positioning pin 403 passes through the square column connector 4 and screws on the nut, so that the suspension bracket 7, the U-mouth joint 6, and the rotating shaft 5 are connected to the steel foot 3 through the square column connector 4. The square column connector 4 serves as a connecting bridge, which can firmly install the suspension bracket 7 on the steel foot 3 and ensure the stability of the entire insulator, so as to help evenly distribute the weight and tension borne by the cable and avoid excessive stress on a certain part. The square column connector 4 makes the connection and fixing process simpler and more efficient, and reduces complicated operation steps. A U-shaped joint 6 is hingedly connected to one side of the top of the suspension bracket 7, and a rotating shaft 5 is fixed to the top of the U-shaped joint 6. The top of the rotating shaft 5 extends into the interior of the square column connector 4 and is rotatably connected to the square column connector 4. An annular groove is provided at one end of the interior of the square column connector 4, and an annular lip is integrally formed on one end of the surface of the rotating shaft 5 to rotatably cooperate with the annular groove. The rotating shaft 5 is rotatably mounted on the bottom end of the square column connector 4, allowing the U-joint 6 and the suspension bracket 7 to perform C-axis circumferential deflection. The U-joint 6 and the suspension bracket 7 are hinged to improve the flexibility of the suspension bracket 7. The orientation of the suspension bracket 7, the mountain-shaped seat 9, the double-spring cable pressure structure 10 and other components can be freely adjusted according to the direction of the cable. The self-seepage cable support structure 8 includes a Y-shaped cutout portion 801 arranged at the bottom end of the suspension support 7, an arc-shaped suspension plate 802 integrally formed at the bottom of the suspension support 7, and a straight notch 803 arranged inside the arc-shaped suspension plate 802. The suspension support 7 is made of tempered glass, and a glaze layer is formed on the outer surface of the suspension support 7 through a glazing process. During the processing, the tempered glass is heated to a high temperature and then rapidly cooled, so that compressive stress is formed on its surface, thereby greatly enhancing the material's impact resistance and bending resistance. At this time, the strength and toughness of the tempered glass can effectively improve the load-bearing capacity of the suspension support, ensuring that it is not easily damaged or failed during long-term use; and the formation of the glaze layer can effectively improve the corrosion resistance of the suspension support, especially in environments where power equipment is often exposed to wind, rain, moisture, chemicals, etc., which can prevent external corrosive substances from directly eroding the glass surface; The dipping process forms a smooth glaze layer on the surface of tempered glass, reducing surface roughness. This smooth surface not only reduces the adhesion of dirt and dust, but also has a self-cleaning function. When rain or wind blows, water droplets can quickly slide off, carrying away dust or impurities on the surface. This self-cleaning function helps keep the components clean and reduces the need for manual cleaning. The cable to be supported is located in the arc-shaped suspension plate 802. In rainy and snowy weather, rainwater covering the cable can flow out of the suspension seat 7 along the arc-shaped outer wall of the cable, the straight groove 803, and the Y-shaped cutout 801, thereby reducing the collection of rainwater.

[0020] Example 3, based on Example 2, Figure 1 and Figure 2 The bolting structure includes a notch 701 provided on the outer wall of one side of the suspension seat 7 and a perforated rocker plate 901 integrally formed on both sides of the top of the mountain-shaped seat 9. The mountain-shaped seat 9 is plugged into the notch 701. An internal threaded hole 702 is provided on the outer wall of the suspension seat 7 on one side of the notch 701. The perforated rocker plate 901 and the internal threaded hole 702 are bolted together by bolts. When the mountain seat 9 is assembled with the suspension bracket 7, the mountain seat 9 is inserted into the notch 701 on the outer wall of the suspension bracket 7 until the perforated seesaw plate 901 contacts the suspension bracket 7. Then, the perforated seesaw plate 901 and the suspension bracket 7 are fastened with bolts and internal threaded holes 702 to complete the assembly of the mountain seat 9 and the suspension bracket 7. The double-spring cable pressure structure 10 includes a support shaft 1001 fixed to one end of the inner side of the mountain seat 9, connecting clips 1002 fitted at both ends of the surface of the support shaft 1001, and a pressure arm 1003 integrally formed at one end of the two connecting clips 1002 away from the mountain seat 9. A U-shaped notch 1004 is provided at the end of the connecting clip 1002 close to the mountain seat 9. A torsion spring 1005 is installed on the outer circumference of the support shaft 1001 at the U-shaped notch 1004. One end of the torsion spring 1005 abuts against the bottom end of the mountain seat 9. An inner groove is provided on the outer wall of the connecting clip 1002 close to the torsion spring 1005. The other end of the torsion spring 1005 extends into the inner groove. After the mountain seat 9 and the suspension seat 7 are assembled, the pressure arm 1003 will deflect around the support shaft 1001 according to the diameter specification of the cable. During this process, the pressure arm 1003 and the connecting card 1002 will rotate around the support shaft 1001. Since the torsion spring 1005 is located in the U-mouth notch 1004, and one end of the torsion spring 1005 is in contact with the bottom end of the mountain seat 9, and the other end of the torsion spring 1005 is embedded in the connecting card 1002, the torsion spring 1005 is twisted and deformed to generate elastic force, so that the pressure arm 1003 is tightly pressed on the cable, and can provide continuous pressure to ensure that the cable always remains in the correct position to avoid displacement or loosening due to external force; and the pressure can be automatically adjusted according to the force conditions of the cable to avoid damage to the cable due to excessive pressure.

[0021] When the embodiment of the present application is used, the staff first inspects the installation site to ensure that all equipment and tools are ready, including the tempered glass insulator, suspension bracket 7, mountain-shaped bracket 9, double-spring cable pressure structure 10, square column connector 4, etc. Secondly, the staff must fully evaluate the voltage level, climatic conditions and installation environment of the power line to ensure that an appropriate installation plan is adopted. During the installation process, the end of the steel foot 3 away from the tempered glass insulation disk 1 is first accurately docked with the square column connector 4. The through holes provided on the surface of the steel foot 3 can be connected to the square column connector 4 through hardware such as bolts and nuts. Bolt connection to ensure that the connection is firm and reliable, so as to use the square column connector 4 as a stable connection foundation to support the suspension seat 7 and the power cable it supports. At this stage, it is necessary to ensure that the square column connector 4 and the steel foot 3 are correctly fixed, and the position of the steel foot 3 is stable to avoid deviations during the subsequent installation process. Once the steel foot 3 and the square column connector 4 are fixed, the operator can start to install the suspension seat 7 and embed the cable body into the self-seeping cable supporting structure 8, and use the self-seeping cable supporting structure 8 to adjust the cable position by itself and provide sufficient support to ensure that it can firmly support the power cable and reduce the risk of deviations caused by If the cable becomes loose or unstable due to installation errors, the staff needs to install the mountain seat 9 after the cable enters the self-seeping cable supporting structure 8 of the suspension seat 7, that is, fix the mountain seat 9 to the outer wall of the suspension seat 7 through the bolting structure. After the suspension seat 7 and the mountain seat 9 are connected, the double-spring cable pressure structure 10 applies sufficient downward pressure on the power cable to ensure that the cable can be firmly fixed in the suspension seat 7, and ensure that the cable will not slide or loosen due to external force or vibration. At the same time, the double-spring cable pressure structure 10 will adjust itself according to the outer diameter of the cable in the suspension seat 7, and will not cause damage to the cable due to excessive pressure. After completing the above steps, the staff will conduct the final inspection and testing, including checking the stability of the entire support structure to ensure that the suspension seat 7 and the mountain seat 9 will not loosen or wear during long-term operation. In addition, a tension performance test is required to simulate the stress that the power cable may encounter during long-term operation to ensure that it can withstand external loads such as strong winds, ice and snow, and will not affect the stability of the power system due to loosening or falling of the cable. Compared with the use of traditional tension clamps, it not only improves installation efficiency and reduces the tedious steps and high-risk operations required in traditional installation methods, but also enhances the stability and safety of the cable.
