Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to an electrical aging-resistant ultra-high voltage AC suspension insulator string. Background Art

[0002] Thermal aging is a fundamental form of material aging. After prolonged exposure to heat, some insulating materials experience a significant reduction in both flexural and tensile strength.

[0003] There are also protective devices for insulators on the market, but the installation process is complicated. Since the protective cover is fixed by bolts, it is difficult to remove it, which reduces the replacement efficiency and causes the equipment to be unable to be used normally. When the internal insulator needs to be broken or replaced, the protective cover needs to be separated, which increases the difficulty of repairing the protective cover and insulator. Summary of the Invention

[0004] The purpose of the utility model is to provide an electrical aging resistant ultra-high voltage AC suspension insulator string to solve the above-mentioned defects caused by the prior art.

[0005] An electrical aging-resistant ultra-high voltage AC suspension insulator string includes a ceramic skirt and an arc-shaped cover. A positioning disk is provided directly above the ceramic skirt, and a shielding mechanism is provided on the outside of the positioning disk. The shielding mechanism covers the outside of the ceramic skirt to prevent external rain and dust from accumulating on the surface of the ceramic skirt, thereby slowing down aging damage to the ceramic skirt. A positioning mechanism is provided on the other side of the ceramic skirt. The positioning mechanism positions the other side of the arc-shaped cover to prevent the arc-shaped cover from shaking during use, while facilitating the disassembly and assembly of the arc-shaped cover.

[0006] Preferably, the shielding mechanism includes a positioning disk body, a base, a positioning shaft, a curved cover body, a double-sided adhesive strip and a sealing film. The base is connected directly above the positioning disk body, and the positioning shaft is connected to both sides of the positioning disk body.

The other end of the curved cover body is fitted with a sealing film, and the curved cover body is arranged on one side of the ceramic skirt body.

[0007] Preferably, a positioning shaft is passed through the interior of the positioning disc body and connected to the outer side of the arc-shaped cover body.

[0008] Preferably, the positioning mechanism includes a limiting disk body, a slot, a metal rod, a wiring terminal, a fastener and a block.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. During use, the outer side of the arc-shaped cover is directly positioned by the positioning shaft, which facilitates the direct positioning of the arc-shaped cover and the positioning plate.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 5 As shown, the electrical aging resistant ultra-high voltage AC suspension insulator string includes a ceramic skirt 1 and a curved cover 5. A positioning disk 2 is provided directly above the ceramic skirt 1, and a shielding mechanism 7 is provided on the outside of the positioning disk 2. The shielding mechanism 7 covers the outside of the ceramic skirt 1 to prevent external rain and dust from being absorbed on the surface of the ceramic skirt 1, thereby slowing down the aging damage of the ceramic skirt 1. A positioning mechanism 8 is provided on the other side of the ceramic skirt 1. The positioning mechanism 8 positions the other side of the curved cover 5 to prevent the curved cover 5 from shaking during use, and at the same time facilitates the disassembly and assembly of the curved cover 5.

[0023] In this embodiment, the shielding mechanism 7 includes a positioning disk body 2, a base 3, a positioning shaft 4, a curved cover body 5, a double-sided adhesive strip 6 and a sealing film 15. The base 3 is connected directly above the positioning disk body 2, and the positioning shaft 4 is connected to both sides of the positioning disk body 2. The outer side of the positioning shaft 4 is connected to the curved cover body 5, and the outer side of the curved cover body 5 is evenly spaced with double-sided adhesive strips 6. The other end of the curved cover body 5 is fitted with a sealing film 15, and the curved cover body 5 is arranged on one side of the ceramic skirt body 1.

[0024] In this embodiment, a positioning shaft 4 is passed through the interior of the positioning disc body 2 and is connected to the outer side of the arc-shaped cover body 5 . The arc-shaped cover body 5 is positioned by the positioning shaft 4 , thereby improving the convenience of installing the arc-shaped cover body 5 .

[0025] In this embodiment, the positioning mechanism 8 includes a limiting disk body 9, a slot 10, a metal rod 11, a wiring terminal 12, a fastener 13 and a block 14. A slot 10 is provided on the outside of the limiting disk body 9. One side of the block 14 is connected to one side of the arc-shaped cover body 5. The outside of the slot 10 is connected to the other side of the block 14. The metal rod 11 is connected to the inside of the limiting disk body 9. The bottom end of the metal rod 11 is connected to the wiring terminal 12. The metal rod 11 is connected to the fastener 13 through the metal rod 11. The wiring terminal 12 set at the bottom end of the metal rod 11 is connected to the wire for power supply.

[0026] In this embodiment, the metal rod 11 is connected to the limit plate body 9 via a transversely penetrating fastener 13 , and one side of the limit plate body 9 is positioned by the fastener 13 to prevent the limit plate body 9 from loosening.

[0027] In this embodiment, the arc-shaped cover body 5 is connected to the outer side of the card slot 10 via a card block 14 provided on one side, and the other end of the arc-shaped cover body 5 is positioned by the card block 14 .

[0028] The practical application of this type of electrical aging resistant UHV AC suspension insulator string includes the following work contents:

[0029] Step 1: The operator first installs the base 3 on the outside of the electrical tower, connects the base 3 to the outside of the positioning plate body 2 with bolts, and connects the positioning shaft 4 that passes through the outside of the positioning plate body 2 to the outside of the arc-shaped cover body 5, and then positions the outside of the arc-shaped cover body 5. The arc-shaped cover body 5 is used to cover the outside of the ceramic skirt body 1. At the same time, the double-sided tape 6 provided on the outside of the arc-shaped cover body 5 is used to bond it with another group of arc-shaped covers 5, completing the covering of the ceramic skirt body 1 by two groups of arc-shaped covers 5;

[0030] Step 2: The operator pulls the limit plate 9 on the surface of the metal rod 11 to shift the limit plate 9, thereby connecting the slot 10 on the outside of the limit plate 9 with the block 14 on the other side of the arc-shaped cover 5. When the other set of limit plates 9 needs to be positioned, the block 14 of the other set of limit plates 9 can also be installed inside the slot 10, and the two sets of limit plates 9 are bonded together using the double-sided tape 6.

[0031] Step 3: When the ceramic skirt 1 needs to be replaced or repaired, the operator rotates the fastener 13 to separate the fastener 13 from the inside of the metal rod 11, and at the same time, the fastener 13 loosens the back positioning of the limit plate 9, and shifts the limit plate 9 on the surface of the metal rod 11, so that the limit plate 9 loosens the positioning of the clamping block 14 on one side of the arc cover 5;

[0032] Step 4: The ceramic skirt 1 is connected to the wires through the terminal 12 provided at the bottom. The operator can separate the bonded limit plate 9 from the double-sided adhesive strip 6 to facilitate the rotation and opening of the arc cover 5, so that the positioning shaft 4 connected to the outside of the arc cover 5 is extended on the outside of the positioning plate 2. The operator can replace or clean the ceramic skirt 1.

[0033] Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
