Description

Technical Field

[0001] The present invention belongs to the technical field of electric power equipment, and in particular relates to an adaptive insulation coordination device. Background Art

[0002] Insulators are devices installed between conductors at different potentials, or between a conductor and a ground-potential component, capable of withstanding voltage and mechanical stress. They are specialized insulating components that play a vital role in overhead transmission lines. In the early days, insulators were primarily used on utility poles. Gradually, they evolved into high-voltage transmission towers, where numerous disc-shaped insulators, typically made of glass or ceramic, are hung from one end to increase creepage distance. Insulators must not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions. Otherwise, they will not be able to effectively function, compromising the service life and operational life of the entire line. An insulator string is an assembly of two or more insulator components combined to flexibly suspend a conductor. They are used to suspend the conductor and insulate it from the tower and the ground.

[0003] Since the insulators in an insulator string are closely spaced, when one insulator is affected by voltage and its temperature rises, it is easy to cause the surface temperature of other insulators to rise, thereby reducing the insulation performance. Summary of the Invention

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; 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.

[0028] Embodiment 1, by Figures 1-6 The present invention includes two fixing plates 1, a middle insulator 2 is installed between the two fixing plates 1, both ends of the middle insulator 2 are inserted into the inside of the fixing slot 8, the fixing slot 8 is opened in the middle of the fixing plate 1, a wire slot 9 is opened on one side of the fixing slot 8, a wire is inserted into the inside of the wire slot 9, and the wire is fixed to both ends of the middle insulator 2, fixing components 4 are symmetrically installed on both sides of the fixing plate 1, and temperature sensing components 5 are also symmetrically installed on both sides of the middle insulator 2.

[0029] Embodiment 2, on the basis of embodiment 1, the fixing assembly 4 includes a first fixing unit 401 and a second fixing unit 402, wherein the first fixing unit 401 includes a connecting rod 4011 symmetrically installed between the two fixing plates 1, a swivel 4012 is installed in the middle of the connecting rod 4011, a telescopic plate 4013 is installed at the bottom end of the swivel 4012, a clamp 4014 is provided at the bottom end of the telescopic plate 4013, and the telescopic rod is sleeved inside the telescopic plate 4013, a telescopic spring is installed at the top of the telescopic rod, and the clamp 4014 is fixedly connected to one end of the telescopic rod, and the second fixing unit 402 includes a slot 4023 symmetrically opened inside the fixing plate 1, a screw 4022 is inserted into the inside of the slot 4023, the screw 4022 is symmetrically installed on one side of the connecting plate 4021, and the connecting plate 4021 is fixedly connected to the side insulator 3, and a bolt is also installed on the outside of the screw 4022;

[0030] During installation, first insert the screw 4022 into the screw hole of the electrical equipment, and then fix the screw 4022 and the screw hole with bolts. Then, after pulling out the telescopic plate 4013, clamp the clamp 4014 to a suitable fixed position, so that the fixing plate 1 is installed.

[0031] Example 3, based on Example 2, the temperature sensing component 5 includes a fixed rod 501 symmetrically installed between the two fixed plates 1, a temperature sensing tube 502 is installed in the middle of the fixed rod 501, an air cavity 504 is symmetrically opened inside the temperature sensing tube 502, a movable block 505 is inserted into the air cavity 504, a transverse spring 506 is installed on one side of the movable block 505, and one end of the transverse spring 506 is installed inside the air cavity 504, limit blocks 507 are symmetrically installed on both sides of the fixed rod 501, and a moving component 6 is further installed on the top of the movable block 505, and a heat transfer ring 503 is installed on the outer side of the temperature sensing tube 502, and the length of the heat transfer ring 503 is the same as the sum of the lengths of the air cavities 504 on both sides;

[0032] When the middle insulator 2 is under the action of voltage, the temperature of the surface of the middle insulator 2 rises. Since a temperature-sensing tube 502 is installed between the middle insulator 2 and the side insulator 3, when heat is transferred to the temperature-sensing tube 502, the heat transfer ring 503 transfers the heat to the inside of the air cavity 504, causing the air inside the air cavity 504 to expand due to the heat. As the temperature rises, the air pressure inside the air cavity 504 increases, thereby pushing the movable blocks 505 on both sides to move outward.

[0033] Example 4, based on Example 3, the moving assembly 6 includes a first rotating seat 601 installed on the top of the movable block 505, a rotating rod 602 is installed on the outside of the first rotating seat 601, one end of the rotating rod 602 is installed on the second rotating seat 603, and a slider 604 is installed on one side of the second rotating seat 603. The slider 604 is slidably connected to the inside of the movable groove 608, and the movable groove 608 is symmetrically opened on one side of the fixed plate 1. The bottom end of the slider 604 is installed with a bottom spring 606, and the two sides of the movable groove 608 are symmetrical. A card slot 609 is provided, and a card strip 605 is inserted into the card slot 609. The card strips 605 are symmetrically installed on both sides of the slider 604. The top of the slider 604 is provided with an arc slot 607. Side insulators 3 are fixedly installed in the arc slots 607 on both sides. The side insulators 3 are symmetrically arranged on both sides of the middle insulator 2. Wires are installed at both ends of the side insulators 3 and are inserted into the inside of the connecting slot 610. The connecting slot 610 is provided on one side of the movable slot 608. A wire pulling assembly 7 is also installed on one side of the slider 604.

[0034] When the movable block 505 moves, it drives the first rotating seat 601 to move, thereby causing the rotating rod 602 to rotate, thereby pushing the slider 604 to move upward, and the slider 604 is fixedly connected to the side insulator 3, so that the slider 604 drives the side insulator 3 to move upward in the movable groove 608, thereby increasing the gap between the side insulator 3 and the middle insulator 2, thereby increasing the heat dissipation space between the middle insulator 2 and the side insulator 3, thereby increasing the heat dissipation speed of the middle insulator 2 and the side insulator 3, and reducing the temperature influence between the insulators, thereby improving the insulation performance of the insulator, and achieving the purpose of adaptive adjustment of the insulator.

[0035] Example 5, based on Example 4, the wire pulling assembly 7 includes a connecting plate 701 installed on one side of the slider 604, a tooth groove 702 is equidistantly provided on one side of the connecting plate 701, a belt 703 is provided on the outer side of the tooth groove 702, a transmission gear 704 is installed on the inner side of the top of the belt 703, the transmission gear 704 is rotatably connected to the fixed plate 1, a rotating gear 705 is installed on the inner side of the bottom end of the belt 703, the rotating gear 705 is rotatably connected to the fixed plate 1, and a mounting rod 7 is installed on one side of the rotating gear 705 06, a limit plate 707 is symmetrically installed on the outside of the mounting rod 706, and a turning handle 708 is installed on one side of the outer limit plate 707. The belt 703 is arranged inside the mounting groove 709, and the mounting groove 709 is opened on one side of the connecting groove 610, and a positioning groove 710 is opened at the bottom end of the mounting groove 709. The mounting rod 706 is inserted into the positioning groove 710. Teeth are equidistantly installed on the inner wall of the belt 703, and the teeth are meshed with the tooth groove 702, and the transmission gear 704 and the rotating gear 705 are both meshed with the teeth;

[0036] When the slider 604 moves upward, the tooth grooves 702 on the connecting plate 701 mesh with the teeth on the inner wall of the belt 703, so that the slider 604 moves upward, driving the belt 703 to move. The belt 703 also meshes with the rotating gear 705, so that the rotating gear 705 rotates and drives the mounting rod 706 to rotate. The mounting rod 706 has a wire wound around its outer side. When the mounting rod 706 rotates, the wire is unwound, so that the length of the wire is adapted to the position of the side insulator 3, so that the wires on both sides of the side insulator 3 are always in a taut state, avoiding the change of the wires due to the movement of the side insulator 3, thereby improving the insulation performance of the electrical equipment.

[0037] When maintenance is required, the distance between the middle insulator 2 and the side insulator 3 needs to be adjusted. At this time, the handles 708 at both ends are rotated so that the handles 708 drive the rotating gear 705 to rotate, so that after the rotating gear 705 rotates, the belt 703 is driven to rotate, and then the belt 703 moves to drive the slider 604 to move upward, so that the slider 604 pushes the side insulator 3 to move upward, thereby increasing the gap between the middle insulator 2 and the side insulator 3, thereby facilitating the maintenance of the insulators, thereby shortening the maintenance speed and improving the maintenance efficiency.
