Description

Technical Field

[0001] The present application relates to the field of reactors, and in particular to an iron core column and a three-phase magnetically controlled reactor. Background Art

[0002] The reactor is an electronic component that is often installed in a circuit to limit current fluctuations in the circuit. Since the coil and core of the reactor will generate a lot of heat during use, it is necessary to apply additional heat dissipation measures to the heat accumulation areas of the coil and core of the reactor while dissipating the heat naturally to ensure the stable operation of the reactor.

[0003] Currently, the two most common cooling methods are air cooling and water cooling. However, cooling the reactor by air cooling will generate a lot of noise, and cooling the reactor by water cooling not only requires the cooling pipe to be wrapped around the surface of the reactor, causing the size of the reactor to become larger, but also water cooling may cause water leakage, resulting in corrosion to the reactor or even damage to the reactor. Summary of the invention

[0025] The following is combined with Figure 1 —6 Provide further details of this application.

[0026] In the first aspect, the present application embodiment discloses an iron core column, referring to Figure 1It includes an iron core column body 1, two heat dissipation tubes 11 made of heat conductive material and two heat conductive plates 12 made of heat conductive material. The heat conductive plates 12 are fixedly mounted on the end surface of the iron core column body 1, one end of the two heat dissipation tubes 11 are respectively fixedly mounted on the two heat conductive plates 12, and the other end of the heat dissipation tube 11 is fixedly connected to the heat dissipation shell of the reactor coil.

[0027] The heat of the core column body 1 is conducted to the heat dissipation shell of the reactor coil through the heat conduction plate 12 and the heat dissipation pipe 11 , and then the heat is dissipated through the heat dissipation shell of the reactor coil, thereby improving the heat dissipation efficiency of the core column body 1 .

[0028] In a second aspect, the present application discloses a three-phase magnetically controlled reactor, referring to Figure 2 and Figure 3 , including a frame 2, a reactor body 21, a temperature detection mechanism 3, a cooling fan 22, a water cooling device 23 and a water leakage alarm device 6 for checking whether the water cooling device 23 is leaking.

[0029] The iron core column in the reactor body 21 mentioned above adopts the iron core column mentioned above.

[0030] Reference Figure 2 and Figure 3 The cooling fan 22 is fixedly mounted on the frame 2 to blow air toward the heat accumulation area of ​​the reactor body 21, and the water cooling device 23 is used to perform water cooling on the air inlet end of the cooling fan 22 to provide cold air.

[0031] Reference Figure 3 and Figure 4 A fan knob 24, a cooling knob 25 and a transmission mechanism 4 are also fixedly mounted on the frame 2. The fan knob 24 is used to control the speed of the fan, the cooling knob 25 is used to control the cooling effect of the water cooling device 23, and the transmission mechanism 4 is used to transmit and connect the temperature detection mechanism 3, the cooling knob 25 and the fan knob 24.

[0032] After the temperature of the heat accumulation part of the reactor body 21 is detected by the temperature detection mechanism 3, the temperature detection mechanism 3 drives the fan knob 24 and the cooling knob 25 to rotate through the transmission mechanism 4, and then controls the cooling fan 22 and the water cooling device 23 to force heat dissipation of the heat accumulation part of the reactor body 21.

[0033] Reference Figure 3 and Figure 5The temperature detection mechanism 3 includes a heat-conducting rod 31 fixedly mounted on the top of the frame 2, a mounting box 32 fixedly mounted on the frame 2, a push rod 35 provided on the mounting box 32, a thermistor spring 33 and a reset spring 34. A heat-insulating layer is provided inside the side wall of the mounting box 32. One end of the heat-conducting rod 31 vertically extends to the highest heat accumulation part of the reactor body 21. The other end of the heat-conducting rod 31 is inserted into the mounting box 32 to introduce heat into the mounting box 32. The thermistor spring 33 is made of memory metal. When the thermistor spring 33 is stretched and then heated, it will return to its original shape.

[0034] Reference Figure 3 and Figure 5 The push rod 35 is slidably mounted on the installation box 32, the thermosensitive spring 33 is sleeved on one end of the push rod 35 located inside the installation box 32, and the two ends of the thermosensitive spring 33 are respectively fixedly connected to the installation box 32 and one end of the push rod 35. The reset spring 34 is sleeved on one end of the push rod 35 located outside the installation box 32, and the two ends of the reset spring 34 are respectively fixedly connected to the side wall of the installation box 32 and one end of the push rod 35. The reset spring 34 is a tension spring. Under normal conditions, the reset spring 34 pulls the thermosensitive spring 33 apart through the push rod 35. When the thermosensitive spring 33 is heated and restored, it pushes the push rod 35 to open the reset spring 34.

[0035] Reference Figure 3 and Figure 4 The transmission mechanism 4 includes a connecting rod 41 slidably mounted on the top of the frame 2, a rack 42 integrally provided on one end of the connecting rod 41, a first gear 43 rotatably mounted on the frame 2 and meshing with the rack 42, and a transmission assembly 5 for transmitting the rotation of the first gear 43 to the fan knob 24 and the cooling knob 25.

[0036] Reference Figure 3 and Figure 4 The end of the connecting rod 41 away from the rack 42 is fixedly connected to the push rod 35, and the connecting rod 41 is pushed to slide by the push rod 35. The transmission assembly 5 includes a mounting shaft 56 rotatably mounted on the frame 2, and a first incomplete gear 52 and a second incomplete gear 53 coaxially fixedly mounted on both ends of the mounting shaft 56. The second gear 51 meshing with the first gear 43 is coaxially fixedly mounted on the mounting shaft 56, the first driven gear 54 meshing with the first incomplete gear 52 is coaxially fixedly mounted on the fan knob 24, and the second driven gear 55 meshing with the second incomplete gear 53 is coaxially fixedly mounted on the cooling knob 25.

[0037] Reference Figure 3 and Figure 4At room temperature when the reactor body 21 is not started, the push rod 35 and the connecting rod 41 are located at the initial position, and the cooling knob 25 and the fan knob 24 are both located at the stop position. When the reactor body 21 starts to accumulate heat, the thermal spring 33 pushes the push rod 35 and the connecting rod 41 to slide, and then drives the first gear 43 and the second gear 51 to rotate through the rack 42, and the rotation of the second gear 51 drives the first incomplete gear 52 and the second incomplete gear 53 to rotate.

[0038] Reference Figure 3 and Figure 4 When the first incomplete gear 52 is meshed with the first driven gear, the second incomplete gear 53 is separated from the second driven gear 55 . When the first incomplete gear 52 is rotated to separate from the first driven gear 54 , the second incomplete gear 53 is meshed with the second driven gear 55 .

[0039] Through the above design, when the reactor body 21 just starts to accumulate heat, if the heat dissipation can be completed only by blowing natural air through the cooling fan 22, the water cooling device 23 will not be started. When the full power operation of the cooling fan 22 cannot meet the heat dissipation demand, the second incomplete gear and the second driven gear 55 engage to start the water cooling device 23 to cool the air at the air intake end of the cooling fan 22, thereby enhancing the cooling effect of the cooling fan 22.

[0040] During use, if the water cooling pipe of the water cooling device 23 is corroded and leaks, the air blown to the reactor body 21 will contain a large amount of moisture. Long-term exposure to high-humidity air will also easily cause damage to the reactor body 21. Therefore, a leakage alarm is required through the water leakage alarm device 6.

[0041] Reference Figure 2 and Figure 4 The water leakage alarm device 6 includes a protective shell 61 fixedly mounted on the frame 2 at the air inlet end of the cooling fan 22, a water detection mechanism 7 arranged on the protective shell 61, and a reverse thrust mechanism 8 arranged on the frame 2 for reverse thrust connecting rod 41.

[0042] Reference Figure 2 and Figure 4 The water cooling device 23 is fixedly installed on the protective shell 61. The protective shell 61 is provided with an air inlet and an air outlet. The air outlet is opposite to the air inlet of the cooling fan 22. The water cooling pipe of the water cooling device 23 is fixedly installed in the protective shell 61 to cool the air in the protective shell 61.

[0043] Reference Figure 2 and Figure 6The water detection mechanism 7 includes a mounting box 32 fixedly mounted on the bottom wall of the protective shell 61 and a short-circuit protection circuit disposed in the mounting box 32. A drain port 611 is provided at the bottom of the protective shell 61. If water leaks in the protective shell 61, the leaked water will be discharged from the drain port 611 of the protective shell 61. The top wall of the mounting box 32 is funnel-shaped. A guide tube 72 is fixedly mounted in the middle of the top wall of the mounting box 32. One end of the guide tube 72 extends to the short-circuit protection circuit. After dripping, the water will be gathered by the top wall of the mounting box 32, and then drip along the guide tube 72 onto the short-circuit protection circuit, causing the short-circuit protection circuit to short-circuit and disconnect.

[0044] Reference Figure 2 and Figure 6 At the same time, a desiccant layer 73 is fixedly laid on the inner wall of the installation box 32. The guide tube 72 reduces the contact between the installation box 32 and the outside world, and the desiccant layer 73 absorbs moisture inside the installation box 32. The combination of the two makes the short-circuit protection circuit in the installation box 32 not easily disturbed by external moisture.

[0045] Reference Figure 2 and Figure 4 The reverse thrust mechanism 8 includes a power-on self-locking motor 83 fixedly mounted on the frame 2 and connected in series to the short-circuit protection circuit, a push rod 81 slidably mounted on the frame 2, a baffle 85 fixedly mounted on the push rod 81, a push block 84 fixedly mounted on the shaft of the power-on self-locking motor 83, and a reverse thrust spring 82 sleeved on one end of the push rod 81. The power-on self-locking motor 83 is powered by the short-circuit protection circuit.

[0046] Reference Figure 2 and Figure 4 After the self-locking motor 83 is powered on, the top block 84 on its shaft presses against the baffle 85, and the two ends of the reverse spring 82 press against the baffle 85 and the frame 2 respectively, and the reverse spring 82 is compressed at this time. The top rod 81 is opposite to the rack 42. When the self-locking motor 83 is powered off, the reverse spring 82 pushes the top rod 81 to slide through the baffle 85, and then pushes the rack 42 to slide in the opposite direction through the top rod 81. When the reverse spring 82 stabilizes again, the rack 42 slides to drive the second incomplete gear 53 to rotate, and the second driven gear 55 is separated again. At this time, the cooling knob 25 rotates to the water cooling device 23 to stop.

[0047] Through the above-mentioned scheme, the water cooling device 23 can be stopped in a more timely manner. Compared with directly connecting the short-circuit protection device in series with the water cooling device 23, it is less likely to cause damage to the water cooling device 23 due to a short circuit. Between repairing the water cooling device 23 and repairing the power-on self-locking motor 83, it is obviously more cost-effective and convenient to repair or replace the power-on self-locking motor 83.

[0048] An alarm light 9 and a start switch 91 for starting the alarm light 9 are fixedly mounted on the protective shell 61. When the push rod 81 slides under the push of the reverse thrust spring 82, the baffle 85 pushes the top block 84 to press the start switch 91 to start the alarm light 9 to sound an alarm.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
