Description

Technical Field

[0001] The present invention relates to the technical field of electrical components, in particular to an adjustable air-core reactor and a method. Background Art

[0002] Reactors, also called inductors, provide inductance in circuits and play roles in limiting short-circuit current and providing inductive reactive power in different situations. Structurally, they are divided into iron-core reactors and air-core reactors. The magnetic circuit of the air-core reactor is air, there is no saturation phenomenon, and the reactance value is a fixed value. Therefore, it is widely used in power systems. At present, the newer domestic air-core reactors with adjustable inductance use resin casting as the encapsulation method for the coil. The adjustable performance of this reactor is poor, and the reactance value of the product cannot be adjusted as needed. To address this problem, the existing patent announcement number CN105529164B provides an open air-core reactor with adjustable inductance. Although the reactance value of this product can be adjusted as needed, this adjustment is relatively fixed and not flexible enough, and the heat dissipation is only carried out by constructing an air duct. The heat dissipation is affected by the surface resin and the effect is not good. In order to improve the heat dissipation effect, the existing patent announcement number CN110491650 B provides a hollow reactor. This device dissipates heat by constructing a guide channel in contact with the inductor wire. However, the heat dissipation here is only internal passive convection heat dissipation, and the heat dissipation limitation is large.

DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0034] In one embodiment, Figures 1-9As shown, an adjustable air-core reactor includes a support platform 27 and a winding column 11 arranged at the upper end thereof, an inductor 12 is wound around the outside of the winding column 11, and the inductor 12 is spirally sleeved on the surface of the winding column 11. An inner channel 13 is provided inside the winding column 11, and a vertically arranged connecting frame 23 is provided on the right side of the inductor 12. The upper and lower ends of the connecting frame 23 are connected and fixed to the winding column 11 through a connecting cross bar frame 15. A terminal block 21 for wiring is provided on the side of the connecting frame 23, and a terminal head for wiring is provided on the terminal block 21. The terminal block 21 is electrically connected to the inductor 12 through an adjustment unit. The adjustment unit can adjust the reactance value of the product during actual use as needed; a protective cover 19 for protecting the adjustment unit is provided on the right side of the connecting frame 23;

[0035] The outer side of the winding column 11 is provided with a resin layer for covering the inductor 12, and the right side of the resin layer is provided with a power connection notch that matches the power connection rod 16;

[0036] A refrigerant channel 14 for heat dissipation is provided inside the winding column 11, a return channel is provided between the connecting cross bar frame 15 and the connecting vertical frame 23, a cache channel is provided inside the support platform 27, and the return channel connects the refrigerant channel 14 and the cache channel to form a circulation structure, and heat dissipation fins 37 for increasing the heat dissipation area are distributed on the lower end surface of the support platform 27, and an isolation box 31 for covering the heat dissipation fins 37 is provided at the lower end of the support platform 27, and an air inlet hole 34 is provided at the lower end of the isolation box 31, and an exhaust duct 24 for exhaust is provided on the outside of the isolation box 31, and an air intake duct 35 passes through the support platform 27, and the lower end of the air intake duct 35 passes through the isolation box 31, and the air intake duct 35 is rotatably set on the support platform 27, located The outside of the intake duct 35 of the cache channel is provided with a fluid blade 32, and the inside of the intake duct 35 is provided with an intake blade 36 for promoting airflow. The upper end of the intake duct 35 extends to the inside of the winding column 11. When the product is working, the inductor 12 generates heat, which heats the liquid inside the refrigerant channel 14. The heated liquid rises, thus causing the liquid to flow clockwise in the circulation structure, thereby completing the circulation heat dissipation. While the liquid is flowing, under the action of the fluid, the fluid blade 32 drives the intake duct 35 to rotate, and the intake duct 35 drives the intake blade 36 to rotate. When the intake blade 36 rotates, it sends external cold air into the inner channel 13, thereby sending away the heat inside the inner channel 13, further improving the heat dissipation effect.

[0037] It should be noted that the support platform 27 is internally provided with an arc-shaped blocking block that cooperates with the fluid blades 32. The arc-shaped blocking block is staggered with the connecting crossbar frame 15. In this way, the fluid blades 32 on one side of the intake duct 35 are subjected to force, prompting the intake duct 35 to rotate.

[0038] The support platform 27 is further provided with a circulation unit for promoting the flow of liquid in the circulation structure. The control end of the circulation unit is electrically connected to a temperature sensor, which is provided on the surface of the winding column 11. When the temperature is higher than the set value, the circulation unit starts to work, thereby achieving active heat dissipation.

[0039] The circulation unit includes a rotating column 52 rotatably arranged on the outside of the support platform 27, and the rotating column 52 is connected to a rotating drive member for driving its rotation. A fluid push ring 29 for pushing the liquid to flow upward is rotatably provided at the top of the cache channel at the lower port of the refrigerant channel 14. Blades that push the liquid to flow upward are distributed on the fluid push ring 29. A second transmission friction ring 53 is provided on the outside of the fluid push ring 29, and a first friction wheel 38 that cooperates with the second transmission friction ring 53 is provided on the inside of the rotating column 52. When the rotating column 52 rotates, the friction between the first friction wheel 38 and the second transmission friction ring 53 drives the fluid push ring 29 to rotate, and the blades on the fluid push ring 29 push the liquid to flow upward along the refrigerant channel 14. This active acceleration method helps to improve the heat dissipation effect;

[0040] The circulation unit also includes a blowing module for blowing air to the outside of the winding column 11. When the temperature exceeds the set temperature, the blowing module can further improve the heat dissipation effect. The blowing module includes a rotating side disk 26 rotatably arranged at the upper end of the support platform 27. The rotating side disk 26 is coaxially arranged with the winding column 11. An air guide cavity is provided inside the rotating side disk 26. The upper end surface of the rotating side disk 26 is a conical surface facing the winding column 11. A plurality of air blowing nozzles 28 are distributed on the conical surface. An air intake notch is provided on the outside of the rotating side disk 26. A guide blade 25 for guiding air to the inside is provided at the position of the air intake notch. A first transmission friction ring 50 is provided at the lower end of the rotating side disk 26. A second friction wheel 47 is provided at the outer end of the rotating column 52, which cooperates with the first transmission friction ring 50. The pressing surface of the second friction wheel 47 is a conical surface, which makes it fit better with the first transmission friction ring 50. The second friction wheel 47 is connected to an expansion pusher for driving its lateral movement. When the temperature is lower than the set value, the second friction wheel 47 is separated from the first transmission friction ring 50, and the blowing module does not work at this time. When the liquid temperature inside the refrigerant channel 14 reaches the target position, the expansion pusher will drive the second friction wheel 47 to contact the first transmission friction ring 50, thereby providing power for the rotation of the rotating side plate 26. When the air nozzle 28 revolves around the winding column 11, it can evenly dissipate heat from the outside of the winding column 11.

[0041] The expansion pusher includes an expansion filler cavity 39 provided inside a rotating column 52, an expansion piston block 54 being slidably provided in the expansion filler cavity 39, the right side of the expansion piston block 54 being filled with an expansion filler, which may be mercury, and the left end of the expansion piston block 54 being connected to an expansion transmission rod 51, the cross-section of the expansion transmission rod 51 being rectangular or elliptical, the rotating column 52 being provided with a sliding through-hole for facilitating the sliding of the expansion transmission rod 51, and the end of the expansion transmission rod 51 being provided with a mounting end for facilitating the connection of the second friction wheel 47, when the liquid temperature reaches the target value, the expansion filler expands, thereby pushing the expansion piston block 54 to slide, the expansion piston block 54 driving the expansion transmission rod 51 to move, and the second friction wheel 47 at the end of the expansion transmission rod 51 will move accordingly, so as to be tightly pressed into the first transmission friction ring 50;

[0042] The isolation box 31 is further provided with a spray mechanism for spraying water onto the surface of the heat dissipation fins 37. The air inlet duct 35 where the air inlet hole 34 is located is provided with a blowing blade 33 on the outside. The air inlet duct 35 is provided with a blowing blade 33 on the outside for blowing air onto the heat dissipation fins 37. The spray mechanism sprays water mist onto the heat dissipation fins 37 and the lower end surface of the support platform 27. The evaporation of the water mist absorbs heat, thereby improving the heat dissipation effect.

[0043] The spray mechanism includes an annular tube arranged on the inner wall of the isolation box 31, and an atomizing nozzle 30 is provided on the surface of the annular tube for spraying toward the heat dissipating fins 37. The water inlet end of the annular tube is connected to the injection cylinder 42, and the water outlet end of the injection cylinder 42 is provided with a one-way valve. The water inlet of the injection cylinder 42 is connected to the liquid extraction pipe 41, and the liquid extraction pipe 41 is provided with a one-way water inlet valve. The lower end of the liquid extraction pipe 41 extends into the liquid storage tank 40, and the liquid storage tank 40 is filled with water. A piston block is provided for sliding inside the injection cylinder 42, and a tail plate 43 is provided at the end of the piston rod at the left end of the piston block. The piston block is connected to the inner wall of the injection cylinder 42 by a return spring, and a pushing cam 44 for squeezing it is provided on the left side of the tail plate 43. The upper end of the pushing cam 44 is connected to the vertical transmission rod, and a locating bearing is provided on the outer side of the vertical transmission rod for rotation. The positioning rod outside the locating bearing is connected to the isolation box 31, and a fourth friction wheel 49 is provided at the upper end of the vertical transmission rod, and a receiving port is provided on the left side of the second friction wheel 47. A third friction wheel 48 corresponding to the fourth friction wheel 49 is provided in the receiving port. The third friction wheel 48 is connected to the inner wall of the receiving port by a receiving spring. The second friction wheel 47 is provided with a limit hole for facilitating the sliding of the expansion transmission rod 51. The inner wall of the limit hole is provided with a limit groove. The outer side of the expansion transmission rod 51 is provided with a limit protrusion that cooperates with the limit hole. The cooperation between the limit protrusion and the limit groove ensures that the second friction wheel 47 and the expansion transmission rod 51 do not rotate relative to each other, but can slide relative to each other. In this way, when the expansion transmission rod 51 is further extended, the third friction wheel 48 will be in close contact with the fourth friction wheel 49, thereby completing further transmission. Under the action of the third friction wheel 48, the fourth friction wheel 49 will drive the push cam 44 to rotate. When the push cam 44 rotates, it will intermittently generate a driving force on the tail plate 43. The liquid inside the injection cylinder 42 will be sprayed out along the atomizing nozzle 30. When the return spring drives the piston block to return, the water in the liquid storage tank 40 will be sucked away to prepare for the next spray.

[0044] It should be noted that the exhaust duct 24 here sends the moist air to a distant place to prevent the moist air from affecting the normal use of the product;

[0045] The rotary drive member includes a driven gear disposed outside the rotating column 52, the driven gear meshing with a driving gear 46, the driving gear 46 being connected to a driving motor 45 for driving the same, the driving motor 45 being mounted outside the isolation box 31. Under the action of the driving motor 45, the driving gear 46 drives the driven gear to rotate, and the driven gear drives the rotating column 52 to rotate, thereby providing power for the rotation;

[0046] The adjustment unit includes two adjustment sliders 18 slidably arranged on the connecting vertical frame 23, and each adjustment slider 18 is provided with a power rod 16 on the side, and the other ends of the two power rods 16 are slidably arranged with the inductance line 12 on the surface of the winding column 11. Each adjustment slider 18 is provided with an adjustment screw hole, and an adjustment screw 22 is provided in the two adjustment screw holes. The lower end of the adjustment screw 22 is rotatably connected to the connecting cross bar frame 15 on the lower side, and the upper end of the adjustment screw 22 passes through the connecting cross bar frame 15 on the upper side, and the upper end of the adjustment screw 22 is provided with an adjustment knob 17 for easy rotation, and the surface of the adjustment knob 17 is provided with an indicator As shown in the arrow, the surface of the connecting crossbar frame 15 where the adjustment knob 17 is located is provided with a scale bar showing the reactance value. The surface of the adjustment screw 22 is provided with a threaded area that cooperates with the two adjustment sliders 18. The two threaded areas rotate in opposite directions. The adjustment knob 17 drives the adjustment screw 22 and the adjustment slider 18 to rotate relative to each other. Under the action of the thread, the two adjustment sliders 18 slide along the connecting vertical frame 23, thereby adjusting the distance between the two adjustment sliders 18. The closer the distance between the two adjustment sliders 18, the smaller the effective reactance value of the inductor line 12. The two adjustment sliders 18 are electrically connected to the terminal block 21 through the wire 20;

[0047] The width of a single connection rod 16 is greater than the pitch of the inductor line 12 , thereby avoiding the problem of disconnection between the connection rod 16 and the inductor line 12 .

[0048] The above embodiment discloses an adjustable air-core reactor, wherein, in actual use, the product is connected to the circuit through the terminal board 21, and the adjusting screw 22 and the adjusting slider 18 are driven to rotate relative to each other by the adjusting knob 17. Under the action of the thread, the two adjusting sliders 18 slide along the connecting vertical frame 23, thereby adjusting the distance between the two adjusting sliders 18, thereby completing the adjustment of the reactance value; when the product is working, the inductor 12 generates heat, and the heat heats the liquid inside the refrigerant channel 14. The heated liquid rises, thus causing the liquid to flow clockwise in the circulation structure, thereby completing the circulation heat dissipation. While the liquid is flowing, under the action of the fluid, the fluid blades 32 drive the air intake duct 35 to rotate, and the air intake duct 35 drives the air intake blades 36 to rotate. When the air intake blades 36 rotate, they send the external cold air into the inner channel 13, thereby sending the heat inside the inner channel 13 away, further improving the heat dissipation effect; When the temperature of the liquid inside the refrigerant channel 14 reaches the target position, the expansion pusher will drive the second friction wheel 47 to contact the first transmission friction ring 50, thereby providing power for the rotation of the rotating side disk 26. When the air nozzle 28 revolves around the winding column 11, it can evenly dissipate heat to the outside of the winding column 11; in this way, when the expansion transmission rod 51 is further extended, the third friction wheel 48 will be in close contact with the fourth friction wheel 49, thereby completing further transmission. Under the action of the third friction wheel 48, the fourth friction wheel 49 will drive the pushing cam 44 to rotate. When the pushing cam 44 rotates, it will intermittently generate a driving force on the tail plate 43. The liquid inside the injection cylinder 42 will be sprayed out along the atomizing nozzle 30. When the reset spring drives the piston block to reset, the water in the liquid storage tank 40 will be sucked away to prepare for the next spray. When the sprayed water mist evaporates, it will absorb a large amount of heat, thereby further improving the heat dissipation effect. The moisture generated in the isolation box 31 will be discharged along the exhaust duct 24.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure.

9. A method for using the adjustable air-core reactor according to claim 8, characterized in that: The following steps are involved: Step 1: Connect the product to the circuit through the terminal board (21), and drive the adjusting screw (22) and the adjusting slider (18) to rotate relative to each other through the adjusting knob (17). Under the action of the thread, the two adjusting sliders (18) slide along the connecting vertical frame (23), and then adjust the distance between the two adjusting sliders (18), thereby completing the adjustment of the reactance value. When the product is working, the inductor (12) will generate heat, and the heat will heat the liquid inside the refrigerant channel (14). The heated liquid will rise, so that the liquid will flow clockwise in the circulation structure, thereby completing the circulation heat dissipation. While the liquid is flowing, under the action of the fluid, the fluid blade (32) will drive the air intake duct (35) to rotate, and the air intake duct (35) will drive the air intake blade (36) to rotate. When the air intake blade (36) rotates, it will send the external cold air into the inner channel (13), thereby sending the heat inside the inner channel (13); Step 2: When the temperature of the liquid inside the refrigerant channel (14) reaches the target position, the expansion pusher drives the second friction wheel (47) to contact the first transmission friction ring (50), thereby providing power for the rotation of the rotating side disk (26), and the air nozzle (28) can evenly dissipate heat on the outside of the winding column (11) when it revolves around the winding column (11); Step 3: When the expansion transmission rod (51) is further extended, the third friction wheel (48) will be in tight contact with the fourth friction wheel (49), thereby completing further transmission. Under the action of the third friction wheel (48), the fourth friction wheel (49) will drive the push cam (44) to rotate. When the push cam (44) rotates, it will intermittently generate a driving force on the tail plate (43). The liquid inside the injection cylinder (42) will be sprayed along the atomizing nozzle (30). When the reset spring drives the piston block to reset, the water in the liquid storage tank (40) will be sucked away to prepare for the next spray. When the sprayed water mist evaporates, it will absorb a large amount of heat, thereby further improving the heat dissipation effect.
