Description

Technical Field

[0001] The present invention relates to the technical field of reactors, and in particular to a reactor. Background Art

[0002] Reactors, also called inductors, are widely used in circuits. Due to electromagnetic induction, they exhibit a certain degree of inductance, which acts as a barrier to current changes. When current flows through a conductor, it generates a magnetic field within the space it occupies. Therefore, all current-carrying conductors generally exhibit inductance. However, the inductance of a long, straight conductor carrying current is small, and the magnetic field generated is weak. Therefore, a typical reactor is a wire wound into a solenoid, called an air-core reactor. Sometimes, to increase the inductance of this solenoid, an iron core is inserted, creating an iron-core reactor. Reactance is categorized into inductive reactance and capacitive reactance. The more scientific classification is that inductive reactance (inductors) and capacitive reactance (capacitors) are collectively referred to as reactors. However, because inductors existed first and were called reactors, capacitors are now referred to as capacitive reactances, while reactors refer specifically to inductors.

[0003] If the internal heat of the reactor cannot be effectively dissipated during long-term operation, it will lead to a series of negative effects. Continuous temperature rise will gradually increase the temperature of the windings and core, exceeding the design allowable range, accelerating the aging process of the insulation material, reducing its dielectric strength and mechanical properties. In severe cases, it may cause partial discharge or even insulation breakdown, threatening the safe operation of the equipment. High temperature will also promote the oxidation and decomposition of mineral insulating oil, generating acidic substances and sludge, which not only affects the cooling and insulation properties of the oil, but may also clog the oil channel, further worsening the heat dissipation conditions, forming a vicious cycle. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a reactor, including a chassis, an iron core and a coil winding, the coil winding is sleeved on the outer surface of the iron core, the lower surface of the iron core is fixedly connected to a lower insulating frame, the lower insulating frame is fixedly connected to the bottom surface of the chassis cavity, the upper surface of the iron core is fixedly connected to an upper insulating frame, the upper insulating frame is fixedly connected to the top surface of the chassis cavity, the iron core and the coil winding are two core components, which together determine the inductance characteristics, energy efficiency and stability of the equipment, by setting the iron core, the main function of the iron core is to provide a low magnetic resistance path, concentrate and enhance the magnetic field, thereby increasing the inductance of the reactor, which is made of stacked silicon steel sheets with high magnetic permeability, and is designed and gas-cooled by segmentation. Gap adjustment is used to prevent magnetic saturation and ensure that the inductance value can be kept stable under high current. The structure of the iron core can also reduce leakage magnetic field and eddy current loss. By setting the coil winding, the coil winding is the conductive part of the inductor. The current-carrying conductor generates an induced magnetic field under alternating current to achieve the inductance effect. The coil winding is wound with copper wire and adopts a pancake structure to meet the requirements of different current and voltage levels. The outer surface of the coil winding is wrapped with insulating oil paper for insulation treatment, which is crucial for voltage resistance and heat dissipation. The number of turns and arrangement can optimize the magnetic field distribution and reduce the additional loss caused by skin effect and proximity effect. By setting the upper and lower insulating frames, the iron core and coil winding can be located in the middle of the chassis cavity.

By setting the iron core 7, the main function of the iron core 7 is to provide a low magnetic resistance path, concentrate and enhance the magnetic field, thereby improving the inductance of the reactor, and is made of stacked silicon steel sheets with high magnetic permeability, through segmented design and air gap Adjustment is performed to prevent magnetic saturation and ensure that a stable inductance value can be maintained under high current. The structure of the iron core 7 can also reduce leakage magnetic field and eddy current loss. By setting the coil winding 8, the coil winding 8 is the conductive part of the inductor, and the current-carrying conductor generates an induced magnetic field under alternating current to achieve an inductive effect. The coil winding 8 is wound by a copper wire and adopts a pancake structure to meet the requirements of different current and voltage levels.

By setting the upper insulating frame 9 and the lower insulating frame 6, the iron core 7 and the coil winding 8 can be located in the middle of the inner cavity of the chassis 1;

[0039] The oil discharge mechanism 2 is used to discharge viscous oil. When the reactor works for a long time, the insulating oil stored in the inner cavity of the chassis 1 will produce viscous clumps due to long-term operation. These clumps will adhere to the outer surface of the coil winding 8 and affect the operation of the reactor. Therefore, by providing the oil discharge mechanism 2, when the insulating oil flows inside the chassis 1, the viscous oil with small clumps can be placed at the bottom of the chassis 1, which makes it easier for maintenance personnel to discharge the clumped oil, thereby extending the service life of the reactor.

The end of the coil winding 8 is connected to a terminal 10, and the top of the terminal 10 is connected to a terminal 11. The terminal 11 passes through the chassis 1. By pouring mineral insulating oil into the inner cavity of the chassis 1, it can be in contact with the outer surface of the coil winding 8, and then during operation, the heat on the outer surface of the coil winding 8 can be taken away by the mineral insulating oil. By setting the terminal 10, the terminal 11 can be connected to the coil winding 8, so that current can enter the coil winding 8.

[0044] The oil discharge mechanism 2 includes a base 21, which passes through the lower surface of the chassis 1, and a transparent plate 22 is fixedly connected to the inner wall of the base 21. The outer surface of the base 21 is penetrated by a blocking plate 23, and the blocking plate 23 is frictionally adapted to the lower surface of the transparent plate 22. The end of the blocking plate 23 is fixedly connected to a handle 24, and the outer side surface of the base 21 is penetrated by a discharge valve 25. By setting the transparent plate 22, the viscous small clumps generated by the long-term operation of the mineral insulating oil can pass through the transparent plate 22 into the inner cavity of the base 21. By setting the blocking plate 23 and the handle 24, the mineral insulating oil agglomerated above the transparent plate 22 can be leaked when the blocking plate 23 is pulled out, and the oil agglomerated in the mineral insulating oil can be discharged through the discharge valve 25 after the discharge valve 25 is opened.

[0045] The lifting mechanism 4 includes a hydraulic cylinder 41, and a moving rod 42 is provided at the output end of the hydraulic cylinder 41. The top of the moving rod 42 is fixedly connected to a sliding frame 43, and the sliding frame 43 passes through the chassis 1. The sliding frame 43 is located at one end of the inner cavity of the chassis 1 and is fixedly connected to a pushing mechanism 47. The pushing mechanism 47 includes a guide box 471, and the guide box 471 is fixedly connected to the bottom end of the sliding frame 43. A sieve plate 472 is fixedly connected to the inner wall of the guide box 471. A liquid spray port 473 is passed through the side of the guide box 471 close to the coil winding 8. The outer side of the guide box 471 is fixedly connected to an extrusion frame 474, and a first rotating column 475 is rotatably connected to the inner cavity of the extrusion frame 474. The first rotating column 47 5 is fixedly connected to the outer surface of the anti-skid wheel 476, the end of the first rotating column 475 is fixedly connected to the scraper 477, the scraper 477 is frictionally adapted to the outer surface of the coil winding 8, the end of the extrusion frame 474 away from the first rotating column 475 is rotatably connected to the second rotating column 478, the end of the second rotating column 478 is fixedly connected to the stirring plate 479, the outer surface of the stirring plate 479 is fixedly connected to the anti-skid column 4710, the anti-skid column 4710 is frictionally adapted to the inner wall of the chassis 1, the upper surface of the stirring plate 479 is fixedly connected to the spring 4712, the top of the spring 4712 is fixedly connected to the positioning plate 4711, the positioning plate 4711 is fixedly connected to the upper surface of the extrusion frame 474, and the liquid is set The pressure cylinder 41 can, under control, make the moving rod 42 at the output end move vertically up and down, thereby making the sliding frame 43 move vertically up and down. When the sliding frame 43 moves downward in the inner cavity of the chassis 1, the pushing mechanism 47 will move downward in the inner cavity of the chassis 1, thereby making the mineral insulating oil in the inner cavity of the chassis 1 flow downward. The outer surface of the chassis 1 is fixedly connected to the limiting rod 45, and the outer surface of the limiting rod 45 is slidably connected to the sliding rod 44. The top end of the sliding rod 44 is fixedly connected to the outer surface of the sliding frame 43, and the bottom end of the sliding rod 44 is fixedly connected to the tooth plate 46. By setting the limiting rod 45, the sliding rod 44 can be limited so that the sliding frame 43 is subjected to the pulling force of the moving rod 42. When moving downward, the sliding rod 44 moves vertically up and down on the outer surface of the limit rod 45. By setting the tooth plate 46, the working state of the heat dissipation mechanism 5 can be adjusted. By setting the pushing mechanism 47, the mineral insulating oil in the inner cavity of the chassis 1 can be pushed when moving up and down, so that the mineral insulating oil can circulate in the inner cavity of the chassis 1, and at the same time, the mineral insulating oil attached to the outer surface of the coil winding 8 can be scraped off, so that the mineral insulating oil can fully take away the heat from the outer surface of the coil winding 8. By setting the sieve plate 472, the viscous mineral insulating oil can be blocked to prevent the mineral insulating oil from entering the inner cavity of the guide box 471 and finally spraying it from the liquid spray port 473 to the outer surface of the coil winding 8. By setting the extrusion frame 474,The mineral insulating oil in the inner cavity of the chassis 1 can be circulated during the up and down movement. By providing an anti-skid wheel 476, the anti-skid wheel 476 can be rotated during the up and down movement, thereby driving the scraper 477 and the first rotating column 475 to rotate, thereby accelerating the contact rate between the mineral insulating oil and the coil winding 8. At the same time, the scraper 477 scrapes off the mineral insulating oil adhering to the outer surface of the coil winding 8 to prevent it from becoming sticky due to prolonged contact. The stirring plate 479 can stir the mineral insulating oil in the inner cavity of the chassis 1 during the up and down movement.

[0046] The outer side of the chassis 1 is symmetrically penetrated with a heat dissipation pipe 3, which is made of metal material. The heat dissipation pipe 3 is a flat tube with a rectangular cross-section, and a plurality of copper fins are welded on the outside. The anti-slip wheel 476 is friction-fitted with the inner surface of the heat dissipation pipe 3. By setting the heat dissipation pipe 3, the heat in the mineral insulating oil in the inner cavity of the chassis 1 can be transferred to the air through the heat dissipation pipe 3 during normal operation, thereby achieving heat dissipation of the inductor. The heat dissipation mechanism 5 includes a connection port 51, which passes through the bottom of the outer side of the chassis 1, and the end of the connection port 51 is fixedly connected A cylindrical tube 52 is connected, and holes are opened at both ends of the cylindrical tube 52. The outer surface of the cylindrical tube 52 is rotatably connected to a rotating sleeve 53. The outer surface of the rotating sleeve 53 is fixedly connected to a gear 54. The gear 54 is engaged with the tooth plate 46. By setting a connecting port 51, when the pushing mechanism 47 is pressed downward in the inner cavity of the chassis 1, the mineral insulating oil in the inner cavity of the chassis 1 can enter the inner cavity of the cylindrical tube 52 through the connecting port 51, and then flow evenly into the inner cavity of the rotating sleeve 53 through the holes at both ends. By setting a gear 54, when the tooth plate 46 moves downward, the mineral insulating oil in the inner cavity of the chassis 1 can enter the inner cavity of the cylindrical tube 52 through the connecting port 51. When the gear 54 drives the rotating sleeve 53 to rotate, thereby changing the heat dissipation state, the upper surface of the rotating sleeve 53 is fixedly connected to the support frame 56, the upper surface of the rotating sleeve 53 is penetrated by a connecting pipe 55, the top of the supporting frame 56 is fixedly connected to a heat dissipation bracket 57, the heat dissipation bracket 57 includes a connecting pipe 571, the connecting pipe 571 is fixedly connected to the top of the supporting frame 56, the top of the connecting pipe 55 penetrates the connecting pipe 571, and by providing the connecting pipe 55, the mineral insulating oil in the inner cavity of the rotating sleeve 53 can flow into the connecting pipe through the connecting pipe 55.

The number of the limiting rings 572 is several, and the limiting rings 572 are evenly distributed. The inner cavity of the limiting ring 572 is rotatably connected to a rotating tube 573. The end of the rotating tube 573 is fixedly connected to a heat sink 574. The heat sink 574 is a hollow metal plate. By setting the limiting ring 572, the rotating tube 573 can be limited so that the rotating tube 573 can rotate at the inner circle of the limiting ring 572, thereby changing the angle of the heat sink 574.

[0047] Working principle: During use, after the reactor has been working for a long time, the operator starts the hydraulic cylinder 41, causing the moving rod 42 at the output end of the hydraulic cylinder 41 to move vertically downward. During the movement, the pushing mechanism 47 moves downward in the inner cavity of the chassis 1, and drives the mineral insulating oil in the inner cavity of the chassis 1 to move downward. At the same time, the mineral insulating oil that has become viscous due to long-term work will accumulate on the upper surface of the transparent plate 22 due to gravity. Then the blocking plate 23 is pulled out to allow the mineral insulating oil to fall into the inner cavity of the base 21. Finally, the discharge valve 25 is opened to discharge the waste oil, and then new oil is added to the inner cavity of the chassis 1. While the pushing mechanism 47 squeezes the mineral insulating oil downward, the mineral insulating oil will enter the inner cavity of the cylindrical tube 52 through the connecting port 51, and enter the inner cavity of the rotating sleeve 53 through the holes at both ends, and finally pass through It enters the inner cavity of the connecting pipe 571 through the connecting pipe 55. When the tooth plate 46 moves downward, it will engage with the gear 54, so that the rotating sleeve 53 drives the support frame 56 and the connecting pipe 571 to rotate, so that the heat sink 574 no longer wraps the heat pipe 3, and increases the contact space between the heat sink 574 and the air. When the mineral insulating oil enters the connecting pipe 571 and the connecting pipe 571 is tilted, the multiple heat sinks 574 will be in a parallel and vertical state due to gravity, further increasing the contact area between the heat sink 574 and the air, so that the mineral insulating oil inside the heat sink 574 can be fully dissipated. After the inductor has dissipated heat well, the hydraulic cylinder 41 is reversed to restore the connecting pipe 571 and the heat sink 574 to their original state. Then, under the action of gravity, the mineral insulating oil in the connecting pipe 571 and the heat sink 574 flows back into the inner cavity of the chassis 1.
