They are structurally classified into iron-core and air-core reactors. Air-core reactors have an air-based magnetic circuit, which prevents saturation and maintains a fixed reactance, making them widely used in power systems.
[0003] Reference is made to a hollow reactor disclosed in patent application publication number CN110491650A. The hollow reactor comprises a coil and first and second busbars, each busbar being provided with terminals for electrical connection to an external circuit. Each busbar comprises a ring body and a cross arm, the cross arm extending radially along the coil and disposed on the ring body.

[0037] Compared with the prior art, the present invention has the following beneficial effects:
[0038] 1. The three coil groups are separated and isolated by an isolation plate. The isolation plate uses materials with good magnetic conductivity to limit the magnetic field to a set area, forming a shielding layer to prevent interference between the three coil groups. The spacing between the coil groups only needs to consider the electrical safety distance, and will not increase with the increase in the volume of the reactor. The spacing between the reactors is greatly reduced, saving land occupation area; and the magnetic fields do not affect each other, ensuring the normal operation of the equipment.
[0039] 2. After water is input into the bottom cylinder, the water inside the bottom cylinder is pushed upward and enters the inside of the rising cylinder through the folding tube, thereby pushing the rising cylinder and the rising plate fixedly connected to the top of the rising cylinder to rise, so that the rising plate moves to the gap of the coil group, and the inside of the coil group is cleaned by the brushes at both ends of the rising plate. The rising plate is controlled by controlling the inflow and outflow of water to control the lifting and lowering of the rising plate, thereby achieving the effect of cleaning the gap of the coil group up and down, and the driving part drives the moving frame to swing back and forth along the gap of the coil group, thereby cleaning the gap of the coil group.
[0040] 3. When the driving part drives the moving frame to swing, the cleaning belt and the gap between the coil group swing together, thus forming another way to clean the gap between the coil group. When the rising plate descends, the winding disk is wound by the action of the spring, and the cleaning belt is rewound to the outside of the winding disk. In the process of swinging cleaning, the cooling fan continuously blows air to discharge the cleaned dust, thereby improving the cleaning effect.
[0041] 4. The water flow inside the cooling expansion tube contacts the cleaning belt. First, support the cleaning belt, and the water flow of the cooling expansion tube contacts the hot air inside the coil group, taking away the heat to improve the overall cooling effect. Then it flows out through the connecting water pipe and flows into the first fixed frame, so that the water passes through the water collection pipe, the installation bottom tube, the folding tube, the folding tube, the rising tube and the cooling expansion tube in turn to perform a cooling cycle of the water circuit, and cooperate with the cooling fan to perform a cooling process together. The driving of the cleaning mechanism can be targeted at the inflow of water, and a temperature sensor can be installed inside the support. When the temperature of the coil group reaches the set value, the coil group is cleaned and cooled by a combination of water cooling and air cooling. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] like Figures 1 to 12 As shown, a three-phase integrated air-core reactor includes the following embodiments:
[0059] Example 1: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, it includes three coil assemblies 101 and further includes:
[0060] The mounting bracket 1 has three coil assemblies 101 arranged in a ring around the center of the mounting bracket 1, and an isolation plate 103 is fixedly connected to the top of the mounting bracket 1 to separate the three coil assemblies 101;
[0061] Three mounting supports 2 are arranged in a ring around the center of the mounting bracket 1, and three isolation plates 103 are fixedly connected to the top of the mounting supports 2. A protective layer 102 formed by pouring epoxy resin is provided on the outside of the coil assembly 101, the mounting supports 2, and the mounting bracket 1;
[0062] A cleaning mechanism is provided inside the mounting support 2, the cleaning mechanism comprising a plurality of cleaning members extending into the gaps between the coil assembly 101 and a driving member for driving the cleaning members to swing back and forth around the center of the mounting support 2;
[0063] Three cooling fans 3 are respectively arranged at the bottom of the three mounting supports 2 and fixedly connected to the mounting bracket 1 for dissipating heat for the coil assembly 101 .
[0064] In specific implementation, when the three coil groups 101 are integrated and used, since the installed phase spacing is usually 1.7 times the outer diameter of the reactor 1.7D; the larger the volume of the reactor, the larger the occupied area; when the installation distance is reduced, the magnetic field strength around the reactor will change; the magnetic fields in the three-phase coils affect each other, generating mutual inductance, thereby affecting their electrical parameters, inductance, loss and temperature rise, etc.; causing the equipment to not operate normally and be damaged, etc., so in this solution, the three coil groups 101 are respectively installed on the top of the three mounting supports 2 on the top of the mounting bracket 1, and an isolation plate 103 is set between the three coil groups 101, and the three coil groups 101 are separated and isolated by the isolation plate 103, and the isolation plate 103 uses a material with good magnetic conductivity to limit the magnetic field to a set area to form a shielding layer to avoid interference between the three coil groups 101, so that the spacing between the coil groups 101 only needs to consider the electrical safety distance, and will not increase due to the increase in the volume of the reactor; greatly reducing the spacing between the reactors, saving land occupation area; and the magnetic fields do not affect each other, ensuring the normal operation of the equipment;
[0065] At the same time, a template is set on the outside, and a high-temperature resistant epoxy resin is poured between the mounting bracket 1 and the three coil groups 101 to form a protective layer 102 to protect the whole. At the same time, a cooling fan 3 is set at the bottom of the mounting bracket 2, and air is blown toward the upper coil group 101 through the cooling fan 3, so that the coil group 101 is accurately cooled.
[0066] Example 2: Figure 6 、 Figure 9 、 Figure 10 and Figure 11 As shown, the cleaning parts include:
[0067] The movable frame 4 is disposed below the coil assembly 101 , and a plurality of mounting base cylinders 701 are fixedly connected to the interior of the movable frame 4 ;
[0068] Rising plates 704 are provided in plurality and are respectively provided on the top of the plurality of mounting base cylinders 701 , and brushes for cleaning the gaps between the coil assembly 101 are provided at both ends of the plurality of rising plates 704 ;
[0069] Rising tube 702 is fixedly connected to the bottom of rising plate 704, and a folding tube 706 is fixedly connected between rising tube 702 and mounting base tube 701. When water is introduced into mounting base tube 701, the water flows through folding tube 706 to push rising tube 702 upward and extend to the gap between coil assembly 101.
[0070] The second spring 707 is sleeved on the outside of the folding tube 706, and the two ends of the second spring 707 are fixedly connected to the mounting base 701 and the rising tube 702 respectively, for resetting and supporting the rising tube 702;
[0071] The liquid supply part is used to provide liquid to the multiple installed bottom cylinders 701 to push the rising cylinder 702 to rise.

[0074] A second rotating ring 1001 is rotatably connected to the inner side of the second fixed frame 10 and forms a sealing ring with the second fixed frame 10;
[0075] The water collection pipe 1002 is fixedly connected to the second rotating ring 1001 and communicated with the second fixed frame 10. The other end of the water collection pipe 1002 passes through the movable frame 4 and communicates with multiple mounting base cylinders 701 inside the movable frame 4, and is used to supply water to the mounting base cylinders 701.
[0076] In specific implementation, a large amount of dust will adhere to the gaps of the coil assembly 101 during daily use, and the dust will cause problems in the heat dissipation of the coil assembly 101 itself. Therefore, in this solution, an external delivery pipe is connected to the connecting pipe of the second fixed frame 10, and external water is delivered to the interior of the installation bottom cylinder 701 inside the multiple mobile frames 4 through the second fixed frame 10 through the water collection pipe 1002. When water is input into the installation bottom cylinder 701, the water inside the installation bottom cylinder 701 is pushed upward and enters the rising cylinder 70 through the folding pipe 706. 2, thereby pushing up the rising cylinder 702 and the rising plate 704 fixedly connected to the top of the rising cylinder 702, so that the rising plate 704 moves to the gap between the coil group 101, and the brushes at both ends of the rising plate 704 clean the inside of the coil group 101. The rising plate 704 is controlled by controlling the inflow and outflow of water to control the lifting and lowering of the rising plate 704, thereby cleaning the gap between the coil group 101 up and down, and the driving member drives the moving frame 4 to swing back and forth along the gap between the coil group 101, thereby cleaning the gap between the coil group 101.

[0080] A rotating disk 603 is fixedly connected to the top of the transmission gear 602, and a connecting shaft 605 is fixedly connected to the top of the rotating disk 603;
[0081] A swing plate 604 is provided on the top of the rotating disk 603. The bottom of the swing plate 604 is rotatably connected to a connecting rod 606. The connecting rod 606 is rotatably connected to the fixed frame 5. A sliding groove is provided at one end of the connecting rod 606 close to the rotating disk 603. A connecting shaft 605 extends into the sliding groove and is slidably connected to the swing plate 604. A limiting groove is provided at the other end of the swing plate 604.
[0082] The toggle rod 607 is fixedly connected to the bottom of the connecting support plate 401 , and the toggle rod 607 extends into the limiting groove and is slidably connected to the swing plate 604 .
[0083] During specific implementation, when the rising plate 704 extends to the gap between the coil group 101, a driving motor is installed at the bottom of the fixed frame 5, and the output shaft of the driving motor drives the rotating rod 6 to rotate, and the rotating rod 6 drives the gear plate 601 to rotate, and the gear plate 601 drives multiple meshing transmission gears 602 to rotate, and the transmission gear 602 drives the rotating disk 603 fixed at the top to rotate, and then drives the swing plate 604 to swing back and forth around the connecting rotating rod 606 through the connecting shaft 605 at the top of the rotating disk 603. Since the toggle rod 607 fixedly connected to the bottom of the connecting support plate 401 extends to the inside of the limit slot opened at one end of the swing plate 604, the swing plate 604 drives the toggle rod 607 to swing, and then the toggle rod 607 drives the connecting support plate 401 to rotate around the center of the rotating rod 6, and keeps the same arc swing with the gap between the coil group 101, thereby improving the cleaning effect of the cleaning piece.
[0084] Example 4: Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, the cleaning piece also includes:
[0085] Two support frames 801, the two support frames 801 are fixedly connected to both sides of the mounting base 701;
[0086] The winding reel 802 is disposed inside the support frame 801, and both ends of the winding reel 802 pass through the support frame 801 and are rotatably connected to the support frame 801;
[0087] A fixed cylinder 806 is sleeved on both ends of the winding disk 802, and the fixed cylinder 806 is fixedly connected to the support frame 801. A spring 805 is provided inside the fixed cylinder 806. The two ends of the spring 805 are fixedly connected to the fixed cylinder 806 and the winding disk 802 respectively, and are used to drive the winding disk 802 to reset and rotate;

[0089] The guide roller 804 is rotatably connected to one end of the support frame 801 and is used to guide the cleaning belt 803.
[0090] During specific implementation, when the rising plate 704 is pushed by water and extends to the gap of the coil group 101, the fixedly connected cleaning belt 803 is pulled from the winding position of the winding disk 802 through the two ends of the rising plate 704, so that the cleaning belt 803 contacts the gap of the coil group 101. When the driving member drives the movable frame 4 to swing, the cleaning belt 803 swings in contact with the gap of the coil group 101, thereby forming another way to clean the gap of the coil group 101. When the rising plate 704 descends, the winding disk 802 is wound by the action of the clockwork spring 805, and the cleaning belt 803 is rewound to the outside of the winding disk 802. In the process of swinging cleaning, the cooling fan 3 continuously blows air to discharge the cleaned dust, thereby improving the cleaning effect.
[0091] In this embodiment, a push plate 703 is slidably connected inside the rising tube 702 , and a first spring 705 is provided on the top of the push plate 703 , and both ends of the first spring 705 are fixedly connected to the push plate 703 and the rising plate 704 respectively.

[0094] In specific implementation, when water rushes into the interior of the rising cylinder 702 through the installation bottom cylinder 701, it first contacts the pushing plate 703 inside the rising cylinder 702. When the rising cylinder 702 is pushed to rise as a whole, when the folding tube 706 is in a fully extended state, the water flow continues to push the pushing plate 703 to rise, squeezing the first spring 705. When the water flow pushes the pushing plate 703 higher than the connection point between the water pipe 901 and the rising cylinder 702, the water flow flows through the water pipe 901 into the cooling expansion pipe 902, and the cooling expansion pipe 902 expands. The water flow inside the cooling expansion pipe 902 contacts the cleaning belt 803, first supporting the cleaning belt 803, and then The water flow in the cooling expansion tube 902 contacts the hot air inside the coil group 101, takes away the heat and improves the overall cooling effect, and then flows out through the connecting water pipe 903 and flows into the first fixed frame 904, so that the water passes through the water collection pipe 1002, the installation bottom tube 701, the folding tube 706, the folding tube 706, the rising tube 702 and the cooling expansion tube 902 in sequence, and performs a cooling cycle in the water circuit, and cooperates with the cooling fan 3 to perform a cooling treatment together. In addition, the drive of the cleaning mechanism can be driven according to the inflow of water, and a temperature sensor can be installed inside the support 2. When the temperature reaches the set value, the coil group 101 is cleaned and cooled by a combination of water cooling and air cooling.
