Description

Technical Field

[0001] The invention belongs to the technical field of reactors, and in particular relates to an iron core tuned filter reactor. Background Art

[0002] The iron core tuned filter reactor is a reactor that combines the iron core structure and the tuning filter function. It is mainly used in low-voltage filter cabinets and is used in series with filter capacitors to absorb the harmonic currents generated in the power grid and reduce the impact and harm of harmonics on electrical equipment. Through the coordination of the tuned filter reactor and the capacitor, specific harmonics in the power grid can be effectively filtered out, the system voltage waveform can be improved, and the system power factor can be increased.

[0003] However, the conventional device still has the following problems when used:

All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] For example, see Figures 1 to 9 The present invention provides a technical solution: it includes a reactor body 1, and the upper and lower sides of the reactor body 1 are fixedly connected with heat sinks 12, an iron core body 11 is arranged inside the reactor body 1, and the outer walls of the upper and lower sides of the iron core body 11 are movably plugged with U-shaped heat conductive parts 13, and the opposite sides of the two U-shaped heat conductive parts 13 are fixedly connected to the outer walls of the heat sink 12, the surface of the heat sink 12 is uneven, and the outer wall at the top of the heat sink 12 is fixedly connected with a device shell 2, and the inside of the device shell 2 is fixedly connected with a heat dissipation mechanism, and the outer walls on both sides of the device shell 2 are provided with square grooves.

[0031] The heat is transferred to the heat sink 12 through the U-shaped heat conductor 13, and then dissipated through the heat sink 12. The heat is quickly dissipated into the surrounding environment through the heat sink 12, thereby reducing the temperature of the reactor body 1 and its internal components, avoiding local accumulation of heat, and correspondingly ensuring that the heat can flow quickly along a predetermined path, thereby reducing the stability inside the reactor body 1.

[0032] Embodiment 2, on the basis of embodiment 1, the outer wall at the top of the device shell 2 is fixedly connected with a temperature sensor 21, the outer wall at the top of the device shell 2 is provided with a placement groove, the interior of the placement groove is fixedly connected with a controller 22, the upper part of the interior of the device shell 2 is fixedly connected with a battery 211, the upper side of the interior of the device shell 2 close to the battery 211 is fixedly connected with a motor 23, the output end of the motor 23 is fixedly connected with a threaded rod 24, the outer wall of the threaded rod 24 is threadedly connected with a moving plate 26, the interior of one end of the moving plate 26 is fixedly connected with a push rod 27, the outer wall of the push rod 27 is slidably connected with a driving plate 25, the outer wall of the driving plate 25 passes through the interior of the square groove and is fixedly connected to the outer wall of the insertion head 15, and the upper and lower sides of the push rod 27 are fixedly connected with a limited block 2 10. The opposite sides of the two limit blocks 210 are fixedly connected with support springs 28, and the opposite sides of the two support springs 28 are fixedly connected with the outer walls on both sides of the driving plate 25. The outer wall at the top of the limit block 210 is fixedly connected with a support rod 29, and the outer wall at the top of the support rod 29 is in active contact with the outer wall at the bottom of the driving plate 25. The outer wall at the top of the heat dissipation plate 12 is fixedly connected with a protective shell 3 on one side close to the device shell 2. The interior of the protective shell 3 is fixedly connected with a connector 14, and the interior of the connector 14 is movably plugged with an insertion head 15. The outer wall of the insertion head 15 is slidably connected with the interior of the protective shell 3. Slide grooves are provided on both sides of the outer wall of the protective shell 3. The outer walls on both sides of the insertion head 15 are fixedly connected with U-shaped blocks 31, and the interior of the U-shaped block 31 is slidably connected with the interior of the slide groove.

[0033] By driving the movement of the plate 25, the insertion head 15 can drive the U-shaped block 31 to move downward inside the slide groove on the protective shell 3, so that the insertion head 15 is separated from the connecting head 14, and the power of the reactor body 1 can be cut off, thereby avoiding damage or malfunction of the reactor body 1 caused by overheating, correspondingly extending the service life of the equipment and reducing the maintenance cost, and providing a certain amount of time for cooling.

[0034] Embodiment three, on the basis of embodiment two, the bottom of one end of the driving plate 25 is fixedly connected with the mounting plate 4, the interior of the mounting plate 4 is fixedly connected with the magnetic plate 41, the interior of the rotating block 46 is rotatably connected with the rotating shaft 42, the outer wall of one end of the rotating shaft 42 is fixedly connected with the mounting shell, the interior of the mounting shell is fixedly connected with the magnetic block 2 410, the outer wall on one side of the magnetic block 2 410 and the outer wall on one side of the magnetic plate 41 repel each other with the same polarity, the outer wall on the other end of the rotating shaft 42 is fixedly connected with the fan blade 43, the outer wall on one side of the rotating block 46 is fixedly connected with the mounting sleeve 44, and the interior of the mounting sleeve 44 is rotatably connected to the outer wall of the rotating shaft 42.

[0035] The fan blades 43 are driven to rotate by the rotating shaft 42, thereby increasing the flow of air inside the reactor body 1. By increasing the flow of air inside the reactor body 1, the transfer and dissipation of heat can be accelerated, thereby reducing the temperature of the equipment and protecting the safety of the equipment. The rotation of the fan blades 43 is precisely to achieve this purpose. It uses the principles of aerodynamics to discharge the hot air inside the reactor and at the same time inhale relatively cold air from the outside to form a circulation, thereby improving the heat dissipation efficiency, reducing the power-off time of the reactor body 1, and facilitating the control of the temperature inside the reactor body 1.

[0036] Embodiment 4, on the basis of embodiment 3, mounting rods 2 412 are rotatably connected to the two sides inside the mounting frame 45, the outer walls of the two mounting rods 2 412 are fixedly connected to the driving wheel 47, the opposite side of the two mounting rods 2 412 is fixedly connected to the rotating block 46, the outer wall of one side of the mounting frame 45 is fixedly connected to a protrusion, the side opposite to the two protrusions is rotatably connected to the mounting rod 1 411, the outer wall of the mounting rod 1 411 is fixedly connected to the half gear 48, the outer wall of the half gear 48 is meshingly connected with the outer wall of the driving wheel 47, the interior of the half gear 48 is fixedly connected to the magnetic block 1 49, the outer wall of one side of the magnetic block 1 49 and the outer wall of one side of the magnetic plate 41 repel each other with the same poles.

[0037] The installation sleeve 44 is driven to move by the rotating block 46, and the movement of the rotating block 46 and the installation sleeve 44 can be used to make the rotating shaft 42 drive the fan blades 43 to move accordingly, thereby changing the angle of the fan blades 43. The change in the angle of the fan blades 43 directly affects the air volume and air pressure generated by them, thereby adjusting the air flow speed and direction inside the reactor body 1.

[0038] Embodiment 5, on the basis of embodiment 4, a return spring 5 is fixedly connected to the lower part of the interior of the mounting frame 45, the outer wall of the top of the two return springs 5 ​​is fixedly connected to a mounting seat 51, the interior of the mounting seat 51 is fixedly connected to a connecting rod 52, the outer wall of the connecting rod 52 is rotatably connected to a support plate 53, and the outer wall of the top of the support plate 53 is fixedly connected to the outer wall of the bottom of the rotating block 46.

[0039] The support plate 53 changes the angle along with the rotating block 46 on the connecting rod 52 inside the mounting seat 51. At this time, the reset spring 5 always maintains a vertical movement state and the angle does not change. Maintaining the vertical movement state by the reset spring 5 means that its elastic force is always transmitted in a straight line direction, and there is no component force generated by the angle change. This straight-line transmission ensures the effectiveness and accuracy of the force and prevents energy loss or unnecessary mechanical stress caused by the component force.

[0040] The working principle and use process of the present invention are as follows: during operation, first, when the reactor body 1 is used, the temperature of the reactor body 1 can be transferred to the core body 11 through the setting of the U-shaped heat conductor 13, and then transmitted to the heat sink 12 through the U-shaped heat conductor 13, so that the heat is dissipated through the heat sink 12, and the heat is quickly dissipated to the surrounding environment through the heat sink 12, thereby reducing the temperature of the reactor body 1 and its internal components, avoiding local accumulation of heat, and correspondingly ensuring that the heat can flow quickly along a predetermined path, thereby reducing the stability inside the reactor body 1.

[0041] When the power of the reactor body 1 is large and the heat sink 12 can no longer meet the heat dissipation demand of the reactor body 1, the temperature inside the reactor body 1 will increase. At this time, the temperature sensor 21 is set. When the temperature inside the reactor body 1 reaches the preset value of the temperature sensor 21, the signal sensed by the temperature sensor 21 is transmitted to the controller 22, and then the motor 23 is controlled by the controller 22. The temperature sensor 21 can monitor the temperature inside the reactor body 1 in real time. Once the temperature reaches the preset threshold, a signal is immediately sent out. The real-time monitoring function ensures that the system can detect and respond to abnormal temperature conditions in a timely manner, thereby buying precious time for subsequent heat dissipation measures.

[0042] Then, through the operation of the motor 23, the movable plate 26 can drive the push rod 27 to move downward inside the driving plate 25. While the push rod 27 moves, the upper limit block 210 can be driven to squeeze the support spring 28, thereby pushing the driving plate 25 to move. The existence of the support spring 28 and the pushing process provide a certain stability and buffering effect for the driving plate 25. The spring can absorb part of the energy and slow down the vibration transmission, thereby protecting the driving plate 25 and the insertion head 15 from damage. By utilizing the movement of the driving plate 25, the insertion head 15 can drive the U-shaped block 31 to move downward inside the slide groove on the protective shell 3, thereby separating the insertion head 15 from the connecting head 14, and then the power of the reactor body 1 can be cut off, thereby avoiding damage or failure of the reactor body 1 caused by overheating, correspondingly extending the service life of the equipment and reducing the maintenance cost, and providing a certain amount of time for cooling.

[0043] When the temperature of the reactor body 1 is lowered, the movable plate 26 can drive the push rod 27 to return to its original position, and the push rod 27 can drive the lower limit block 210 to move upward, thereby squeezing the support spring 28, thereby pushing the driving plate 25 to drive the insertion head 15 to move upward. By setting the support rod 29, the support for the driving plate 25 can be increased, thereby increasing the stability of the insertion head 15 inside the connector 14. The automatic reset function ensures that the equipment can quickly return to normal working state after power-off protection, thereby improving the reliability and availability of the equipment. The stability of the support rod 29 helps to ensure that the insertion head 15 maintains close contact inside the connector 14, thereby improving the reliability and safety of current transmission.

[0044] While the driving plate 25 moves downward, the magnetic plate 41 on the mounting plate 4 can be driven to move downward. When entering between the two half gears 48, the magnetic plate 41, the magnetic block 1 49 and the magnetic block 2 410 can enter the inner range of the magnetic force. At this time, the magnetic block 2 410 can drive the rotating shaft 42 to rotate by utilizing the effect of like-pole repulsion between the magnetic block 2 410 and the magnetic plate 41, and then the fan blade 43 can be driven to rotate through the rotating shaft 42, thereby increasing the flow of air inside the reactor body 1. By increasing the flow of air inside the reactor body 1, the transfer and dissipation of heat can be accelerated, thereby reducing the temperature of the equipment and protecting the safety of the equipment. The rotation of the fan blade 43 is precisely to achieve this purpose. It uses the principle of aerodynamics to discharge the hot air inside the reactor and at the same time inhale relatively cold air from the outside to form a circulation, thereby improving the heat dissipation efficiency and reducing the power-off time of the reactor body 1.

[0045] Through the repulsive action between magnet block 1 49 and magnet block 2 410, magnet block 1 49 can drive half gear 48 to rotate, and through the rotation of half gear 48, driving wheel 47 can drive mounting rod 2 412 to rotate, so that rotating block 46 drives mounting sleeve 44 to move, and then by utilizing the movement of rotating block 46 and mounting sleeve 44, rotating shaft 42 can drive fan blade 43 to move accordingly, thereby changing the angle of fan blade 43. The change in the angle of fan blade 43 directly affects the air volume and wind pressure generated by it, thereby adjusting the air flow speed and direction inside reactor body 1.

[0046] It should be noted that the teeth of the two half gears 48 are arranged in opposite directions, so that the two half gears 48 drive the two driving wheels 47 to rotate in different directions.

[0047] When the rotating block 46 is rotated upward, the reset spring 5 can drive the mounting seat 51 to move downward. When the rotating block 46 is tilted, the support plate 53 can change its angle on the connecting rod 52 inside the mounting seat 51 along with the rotating block 46. At this time, the reset spring 5 always maintains a vertical movement state and does not change its angle. Maintaining the vertical movement state by the reset spring 5 means that its elastic force is always transmitted in a straight line direction without any component force caused by angle changes. This straight-line transmission ensures the effectiveness and accuracy of the force and prevents energy loss or unnecessary mechanical stress caused by component force.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
