Description

Technical Field

[0001] The present invention belongs to the technical field of high-voltage tubular busbars, and in particular relates to an adaptively supported high-voltage tubular busbar based on multi-physical field coupling. Background Art

[0002] High-voltage tubular busbars consist of a series of pipes, insulation materials, and connectors. These pipes are typically made of highly conductive materials (such as aluminum or copper) and have a large cross-sectional area to withstand high current loads and reduce resistance losses. The insulation is used to isolate the electromagnetic field between the conductors and the casing, ensuring the safety of power transmission. The casing is usually made of a sturdy material (such as steel) to protect the conductors and insulation materials from environmental corrosion. The main function of the high-voltage tubular busbar is to transmit electricity from one device or area to another. It is commonly used in urban power supply systems, industrial plants, and large buildings to transmit high-voltage electricity from power stations or substations to various power load points. In power systems, high-voltage tubular busbars play a key role in connecting and distributing electricity. High-voltage tubular busbars are efficient, safe, and reliable power transmission devices with broad application prospects and development potential in power systems.

[0003] In smart grid systems, high-voltage tubular busbars need to adapt to dynamically changing power loads. Eddy current losses (approximately 15%-20% of total losses) caused by uneven electromagnetic field distribution in traditional busbars severely restrict grid energy efficiency. Furthermore, smart distribution networks require busbars to have real-time monitoring and adaptive adjustment capabilities to meet the needs of new energy access and load fluctuations. Existing technologies lack coordination with grid monitoring systems and cannot achieve dynamic electromagnetic field optimization. There is an urgent need for an energy-saving high-voltage tubular busbar that is deeply integrated with smart grids.

[0004] However, existing high-voltage tubular busbars do not have the ability to regulate the electromagnetic force field. The uneven distribution of the electromagnetic force field will cause induced electromotive force inside the busbar, thereby inducing eddy currents and causing additional energy loss. It will also cause the local electromagnetic force field intensity to be too high, increasing the risk of insulation breakdown, and thus affecting the normal operation and life of the busbar. Summary of the Invention

[0005] In response to the above situation, in order to overcome the defects of the existing technology, the present invention provides an adaptive supported high-voltage tubular busbar based on multi-physical field coupling, which effectively solves the problem in the above background technology that the existing high-voltage tubular busbar does not have the ability to adjust the electromagnetic force field, and the uneven electromagnetic force field distribution will affect the normal operation and life of the busbar.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) During operation, when the electromagnetic field sensor detects an abnormal electromagnetic force field around it, it will transmit data to the control panel, and the control panel will start the driving motor to operate. When the driving motor operates, it will drive the rotating shaft to rotate inside the bearing through the large gear. When the rotating shaft rotates, it will push the two push-pull rods to move in opposite directions through the transmission bar. When the two push-pull rods move in opposite directions, they will drive the two transmission plates to move in opposite directions through the two moving rods.

When the two transmission plates move in opposite directions, they will drive the eight transmission pins to move through the eight transmission grooves.

When the eight moving blocks move, they will drive the sliders to slide inside the sliding grooves, thereby increasing the stability of the eight positioning hoops when they move. When the eight positioning hoops move, they will drive the four high-voltage tubular busbar bodies to move and expand the spacing, thereby changing the electromagnetic force field between the four high-voltage tubular busbar bodies.

[0018] (2) When the large gear rotates, it also drives the driving sprocket to rotate through the small gear. When the driving sprocket rotates, it drives the driven sprocket to rotate through the chain. When the driven sprocket rotates, it drives the shaft rod to rotate inside the shaft sleeve. When the shaft rod rotates, it drives the threaded sleeve downward through the threaded rod. Since the thread pitch of the threaded rod is large, the threaded sleeve can move quickly. When the threaded sleeve moves downward, it drives the first sliding sleeve to slide on the surface of the first sliding rod through the fixed rod, thereby increasing the stability of the threaded sleeve when it moves. When the threaded sleeve moves downward, it also drives the support arm to move downward. When the support arm moves downward, it drives the three electromagnetic shielding plates to move downward to the four high-voltage tubular busbar bodies for isolation, thereby avoiding electromagnetic mutual influence between the four high-voltage tubular busbar bodies. When the support arm moves downward, it also slides along the surface of the two limit rods through the two limit sleeves, thereby increasing the stability of the three electromagnetic shielding plates when they move downward;

[0019] (3) The high-voltage tube-type busbar has the ability to adjust the electromagnetic force field to avoid uneven electromagnetic force field distribution affecting the normal operation and life of the busbar. BRIEF DESCRIPTION OF THE DRAWINGS

The output end of the drive motor 10 is provided with a transmission assembly, which is transmission-connected to the three electromagnetic shielding plates 8 and the eight positioning hoops 6. When the drive motor 10 is running, power is output to the three electromagnetic shielding plates 8 and the eight positioning hoops 6 through the transmission assembly, so that the three electromagnetic shielding plates 8 move down between the four high-voltage tubular busbar bodies 7 for isolation, and the eight positioning hoops 6 drive the four high-voltage tubular busbar bodies 7 away from each other to change the electromagnetic force field between the four high-voltage tubular busbar bodies 7. A control panel 44 is fixedly installed on one end of the bottom of the support plate 1, and an electromagnetic field sensor 45 is fixedly installed on the top of the support frame 9. The control panel 44 is electrically connected to the electromagnetic field sensor 45 and the drive motor 10;

[0033] The sliding assembly includes eight moving blocks 41, which are respectively fixedly installed at the bottom of the eight positioning hoops 6, and the eight moving blocks 41 are divided into two groups and are equidistantly arranged inside the two strip grooves 26. Slide blocks 42 are fixedly installed on both sides of the eight moving blocks 41, and sliding grooves 43 are provided on the inner walls of both sides of the two strip grooves 26. The sliders 42 are respectively slidably installed in the corresponding sliding grooves 43.

[0034] During operation, when the electromagnetic field sensor 45 detects an abnormality in the surrounding electromagnetic force field, it will transmit data to the control panel 44. The control panel 44 will start the drive motor 10 to operate. When the drive motor 10 operates, it will drive the transmission assembly to operate. When the transmission assembly operates, the eight positioning hoops 6 are driven to move through the eight moving blocks 41. When the eight moving blocks 41 move, they all drive the sliders 42 to slide inside the slide grooves 43, thereby improving the stability of the eight positioning hoops 6 when they move.

[0037] When the drive motor 10 is running, it will drive the small gear 12 to rotate through the large gear 11. When the small gear 12 rotates, it will drive the driving sprocket 14 to rotate. When the driving sprocket 14 rotates, it will drive the driven sprocket 15 to rotate through the chain 16.

[0039] When the shaft 17 rotates, the threaded sleeve 21 is driven downward by the threaded rod 20. Since the thread pitch of the threaded rod 20 is large, the threaded sleeve 21 can move quickly.

When the two push-pull rods 33 move backwards, the two moving rods 34 drive the two transmission plates 35 to move backwards.

[0042] The transmission plates 35 are each provided with four transmission grooves 36 on their surfaces, each of which is inserted with a transmission pin 40. The tops of the eight transmission pins 40 are respectively fixedly connected to the eight moving blocks 41.

One end of the four second sliding rods 38 is respectively fixedly connected to the lower portion of the two support platforms 3, and the other ends of the four second sliding rods 38 are respectively fixedly connected to the side of the two support platforms 3 that is close to each other through fixing brackets 39.

[0043] When the two transmission plates 35 move, they drive the second sliding sleeve 37 to slide on the surface of the second sliding rod 38, thereby increasing the stability of the two transmission plates 35 when moving. When the two transmission plates 35 move in opposite directions, they drive the eight transmission pins 40 to move through the eight transmission grooves 36.

When the grid load suddenly increased from 80% to 120%, the electromagnetic field sensor 45 detected an excessive local electromagnetic field intensity. The control panel 44 then activated the motor 10 to increase the busbar spacing by 15% and simultaneously lowered the electromagnetic shield 8 to isolate the interference. Test results showed that eddy current losses decreased from 18% to 4.2%, reducing the risk of insulation breakdown by 60%.
