Description

Technical Field

[0001] This invention relates to the field of power component technology, specifically to a novel power insulator. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. There are many types of insulators with different shapes. Although different types of insulators have significant differences in structure and appearance, they are all composed of two main parts: insulating components and connecting hardware.

[0003] Conventional insulators have significant limitations in practical applications. They are typically installed as a single unit on the surface of power equipment, with a fixed and non-adjustable structure. This characteristic makes it difficult to adjust them flexibly according to actual operating conditions, hindering efficient use. Moreover, harsh environments become their formidable adversaries during use. Extreme conditions such as strong winds, torrential rains, high temperatures, and extreme cold can cause varying degrees of erosion and damage to insulators, leading to cracks, aging, and other problems, ultimately preventing them from functioning properly and affecting the stable operation of the power system.

[0004] Therefore, it is necessary to design a new type of power insulator that is practical, stable, and efficient. Summary of the Invention

[0005] The purpose of this invention is to provide a novel electrical insulator to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a novel power insulator, comprising a main base, an insulator working mechanism being provided on the top of the main base, and an internal support mechanism being provided on the surface of the insulator working mechanism; The insulator working mechanism includes a base disposed on top of a main seat. A hollow column is fixedly connected to the top of the base. A large umbrella-skirt type insulator is installed on the surface of the hollow column, and a small umbrella-skirt type insulator is also installed on the surface of the hollow column. An insulating material fixing ring is installed on the outer side of the bottom end of the hollow column. A connecting plate is fixedly connected to the outer end of the insulating material fixing ring. A lower windproof cover is fixedly connected to the top of the connecting plate. A detachable connector is installed on the top of the lower windproof cover, and an upper windproof cover is installed on the top of the detachable connector. This device adopts a variable diameter umbrella skirt design, with a large umbrella-skirt type insulator and... The alternating arrangement of small umbrella-shaped insulators and the large umbrella-shaped insulators increase the creepage distance and improve the insulation performance of the insulators. The small umbrella-shaped insulators reduce the accumulation of rainwater on the insulator surface and reduce the risk of flashover. In addition, the edges of the umbrellas adopt a special streamlined design to reduce wind resistance and corona discharge. At the same time, a lower windproof cover and an upper windproof cover are set at the outer end of the insulator. The windproof cover adopts a streamlined design, which can effectively reduce wind resistance and reduce the force of strong wind on the insulator. The setting of this mechanism enhances the efficiency of the insulator itself and improves the overall service life.

[0007] According to the above technical solution, the large umbrella-type insulator and the small umbrella-type insulator are staggered on the surface of the hollow column, and the edges of the large umbrella-type insulator and the small umbrella-type insulator adopt a streamlined design.

[0008] According to the above technical solution, the lower wind shield is fixedly connected to the top outer end of the connecting plate, and the lower wind shield, the detachable connector and the upper wind shield are all located at the outer end of the hollow column.

[0009] According to the above technical solution, the internal support mechanism includes an internal plug-in seat, which is fixedly connected to the center of the top of the base. A main support plug-in column is plugged into the top of the internal plug-in seat. A telescopic column is fixedly connected to the surface of the main support plug-in column. A spring is sleeved on the surface of the telescopic column. An insulating elastic support pad is fixedly connected to the outer end of the telescopic column. A top seat is fixedly connected to the top of the main support plug-in column. A connecting mounting block is installed on the top of the top seat. Fastening bolts are provided on the surfaces of the connecting mounting block and the top seat. A wire frame is fixedly connected to the top of the connecting mounting block. A top wiring block is fixedly connected to the top of the wire frame. During device installation, the internal plug-in... The base and main support plug-in column fix the internal support mechanism inside the hollow column. The overall support effect of the hollow column is ensured by telescopic columns, springs and insulating elastic support pads. The internal support structure is made of high-strength carbon fiber reinforced resin matrix composite material. Carbon fiber has the characteristics of high strength, low density, high modulus and good corrosion resistance, which can effectively improve the mechanical properties of the support structure. The resin matrix plays the role of bonding carbon fiber and transferring load, ensuring the integrity of the entire support structure. The composite material formed by the combination of the two not only ensures the required strength and rigidity of the support structure, but also reduces the overall weight of the insulator, and can also prevent strong winds from affecting the stability of the device.

[0010] According to the above technical solution, the internal plug-in seat is disposed inside the hollow column, and the main support plug-in column, telescopic column, spring and insulating elastic support pad are all disposed inside the hollow column, with the outer end of the insulating elastic support pad contacting the inner wall of the hollow column.

[0011] According to the above technical solution, a height adjustment mechanism is provided on the top of the main seat; the height adjustment mechanism includes an adjustment base, which is fixedly connected to the bottom of the base, and side sliding seats are fixedly connected to the left and right sides of the adjustment base. A fixed adjustment slide rod is fixedly connected to the top of the main seat, and an elastic limiting sleeve is installed on the surface of the fixed adjustment slide rod. A locking element is provided on the surface of the elastic limiting sleeve. A telescopic support column is fixedly connected to the center of the bottom of the adjustment base, and a bottom support cylinder is fixedly connected to the top of the main seat. During the use of the device, the height of the insulator can be finely adjusted by the height adjustment mechanism. The limiting element can be released by removing the locking element on the surface of the elastic limiting sleeve, and the height can be adjusted by sliding the side sliding seats. This adjustable height mechanical structure has the advantages of simple structure, convenient operation, and high adjustment accuracy. Under different terrain conditions, such as mountains, hills, or when the tower height changes relatively due to terrain subsidence, the height of the insulator can be quickly and effectively adjusted to ensure that it maintains a suitable electrical safety distance from the conductor, improve the applicability and stability of the insulator in complex environments, and ensure the reliable operation of the power system.

[0012] According to the above technical solution, the side sliding seat is slidably connected to the surface of the fixed adjusting slide rod, and the side sliding seat is limited to the surface of the fixed adjusting slide rod by the elastic limiting sleeve and the locking member. The telescopic support column is fixedly connected to the inside of the bottom support cylinder.

[0013] According to the above technical solution, the bottom of the main seat is provided with a bottom cable port, the left and right sides of the main seat are fixedly connected with main mounting blocks, the bottom of the main mounting blocks are fixedly connected with cross-shaped inserts, and the front and back of the main mounting blocks are fixedly connected with auxiliary bolt mounting blocks.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This invention, through the provision of an insulator working mechanism, employs a variable-diameter shed design, with large-shed and small-shed insulators arranged alternately. The large-shed insulators increase the creepage distance and improve the insulation performance of the insulators; the small-shed insulators reduce the accumulation of rainwater on the insulator surface, lowering the risk of flashover. In addition, the edges of the sheds adopt a special streamlined design to reduce wind resistance and corona discharge. Simultaneously, a lower windproof cover and an upper windproof cover are provided at the outer end of the insulator. The windproof cover adopts a streamlined design, which can effectively reduce wind resistance and reduce the force of strong winds on the insulator. The provision of this mechanism enhances the efficiency of the insulator itself and improves the overall service life.

[0015] 2. This invention, through the provision of an internal support mechanism, addresses the crucial role of its installation and material selection in ensuring the stability and performance of the device during installation. Specifically, the internal support mechanism is securely fixed within the hollow column via internal connectors and main support connectors. Simultaneously, the synergistic effect of the telescopic column, springs, and insulating elastic support pads effectively guarantees the overall support effect of the hollow column, providing a robust internal support structure for the device. Regarding material selection, the internal support structure utilizes high-strength carbon fiber reinforced resin matrix composite material. This is a high-performance material combination; carbon fiber itself possesses significant characteristics such as high strength, low density, high modulus, and excellent corrosion resistance. These properties enable it to achieve high performance... The improved mechanical properties of the support structure enable it to withstand greater external forces without easily deforming. The resin matrix plays a crucial role in bonding carbon fibers and transferring loads, ensuring the integrity of the entire support structure and allowing all parts to work together to share external forces. The application of this composite material brings many advantages. On the one hand, it guarantees the required strength and stiffness of the support structure, enabling the device to operate stably in various complex environments. On the other hand, it significantly reduces the overall weight of the insulators, lowering the difficulty of installation and maintenance. Furthermore, due to its excellent mechanical properties and stability, it can effectively prevent the impact of severe weather such as strong winds on the stability of the device, further improving the reliability and service life of the device.

[0016] 3. This invention, through the inclusion of a height adjustment mechanism, plays a crucial role in the actual use of the device. It allows for precise fine-tuning of the insulator height, and the operation is extremely simple. Simply remove the locking element from the surface of the elastic limit sleeve to immediately release the limit, then slide the side sliding seat to smoothly adjust the height. This ingenious height-adjustable mechanical structure design has many significant advantages: it is simple in structure, without complex parts or cumbersome assembly procedures; it is easy to operate, requiring no professional tools or complex training, and can be easily mastered by ordinary workers; it has high adjustment accuracy, meeting the precise height requirements of insulators under different working conditions. In complex terrain conditions such as mountains and hills, or when the tower height changes relatively due to terrain subsidence, this mechanism can quickly and effectively adjust the insulator height, ensuring that it always maintains a suitable electrical safety distance from the conductor. This greatly improves the applicability and stability of the insulator in complex environments, providing a solid guarantee for the reliable operation of the power system.
