Description

Technical Field

[0001] The present invention relates to the technical field of inductors, and in particular to an adjustable high-current inductor. Background Art

[0002] Inductors, capacitors, and resistors are known as the three major passive components. They have developed rapidly after capacitors and resistors to achieve chip-type components. Basic principle Self-inductance phenomenon: Electromagnetic induction occurs when the current flowing through the conductor itself changes. When a coil is made of metal wire and the current flowing through the coil changes, a very obvious electromagnetic induction phenomenon will occur. The self-induced reverse electromotive force of the coil hinders the change of current and plays a role in stabilizing the current.

[0003] At present, in order to meet the market demand, adjustable inductors are mostly used. However, the existing inductors are mostly such as the adjustable inductor disclosed in the announcement number CN220509838U, which adopts an inner coil wound on an inner frame, a connecting shaft is electrically connected to the inner coil, and a sleeve is electrically connected to the outer coil. By rotating the inner frame relative to the outer frame around the rotation axis, the relationship between the magnetic field generated by the inner coil and the magnetic field generated by the outer coil can be changed, thereby achieving adjustable inductance. However, the inner coil, the sleeve and the outer coil are connected in a fixed and fitted manner, which makes the adjustment method more complicated, and it is impossible to accurately control the adjustment degree and current inductance between the three.

[0004] Secondly, as disclosed in the announcement number CN107045918B, an adjustable inductor for transformer current flow test has a ventilation system in the adjustable inductor box, which includes a fan arranged in the adjustable inductor box. Wind energy enters the inner cavity of the fixed inductor group and the segmented adjustable inductor group through the wind guide hole and the transverse through hole from the air guide cavity, and then blows to the top vent through the inner cavity of the continuous adjustable inductor. However, when an overload accident occurs in the circuit, if the circuit is not disconnected in time, it is very easy to cause a short circuit accident, and even further cause a serious safety accident.

It should be noted that the center line segment 401 and the two end line segments 402 have the same diameter. The center line segment 401 is in contact with the thick center segment 301, while the two end line segments 402 are not in contact with the thin end segment 302, thereby creating space for the end cover 17 and the magnetic arc isolation plate 18 to move.

[0083] The strong spring 9 is fixedly installed in the guide long hole 7, and the guide push block 10 is slidably mounted in the guide long hole 7. Under the elastic support of the strong spring 9, the guide push block 10 moves linearly, and the guide push block 10 is used to pull and drive the first limit slider 11.

[0084] The first limiting sliding block 11 is slidably installed in the first limiting long groove 8 .

[0085] The limiting clamp 12 is integrally connected to the first limiting slider 11 . Under the elastic force of the strong spring 9 , the limiting clamp 12 clamps and limits the damping shaft 14 in a closed state to prevent the damping shaft 14 from rotating.

[0086] Secondly, the adjustment tool also includes a damping shaft 14, a double-headed swing rod 15, a moving frame 16 movably pulled by the double-headed swing rod 15, an end cover 17 corresponding to the magnetic core 3, and a magnetic arc isolation plate 18:

[0089] The movable frame 16 is slidably mounted on the load-bearing rod 2 .

[0090] The end cover 17 is fixedly mounted on the moving frame 16. The end cover 17 moves back and forth linearly along the load-bearing rod 2 under the traction of the double-headed swing rod 15 to adjust the horizontal position of the magnetic arc isolation plate 18, and the magnetic properties of the magnetic core 3 are controlled on and off to meet the adjustment needs of the inductance.

[0091] Please refer to the instruction manual for details Fig.10 -Attached Fig.12 The circuit breaker is arranged in the main cavity 102 through the conductive terminal 5 and the conductive pin 6. The circuit breaker includes:

[0092] The first part includes a second limiting long groove 20 and a second limiting slider 21 therein, and a conductive plate 22 for contacting and connecting the conductive terminal 5 and the conductive pin 6;

[0093] The second part includes a load-bearing bracket 23, a deflection shaft 24 and a deflection pull rod 26 of a conductive plate 22 for active traction, an electrically connected voltage sensor 29, a central controller 30 and a driving cylinder 31, a booster plate 32, an I-shaped lifting rod 33 and a return spring 34, a placement table 35, a composite capsule 36 with solid sodium azide built in, and a driven gear 25 and a double-sided rack 37 in meshing connection:

[0094] Further explanation:

[0095] The second limit slot 20 is opened in the left-right direction at the bottom end of the main cavity 102 , and the second limit slider 21 is slidably installed in the second limit slot 20 . It should be noted that the second limit slider 21 is made of insulating silica material.

[0096] The conductive plate 22 is fixedly mounted on the second limit slider 21, and the conductive plate 22 is located between the conductive terminal 5 and the conductive pin 6. By driving the conductive plate 22 to move horizontally, when the conductive plate 22 contacts the conductive terminal 5 and the conductive pin 6, the copper wire turn 4 is in a powered state, otherwise the copper wire turn 4 is in a powered-off state.

[0097] The load-bearing bracket 23 is fixedly installed in the main cavity 102. Fig.10 The load-carrying bracket 23 includes a first support 2301 for mounting the deflection shaft 24, a second support 2302 for mounting the voltage sensor 29, the central controller 30 and the driving cylinder 31, and an extension support 2303 for mounting the I-shaped lifting rod 33:

[0098] The first support 2301 is a gantries arranged in two forward and backward directions, and the first support 2301 is fixedly installed at the bottom end of the main cavity 102, so as to facilitate the symmetrical arrangement of the deflection shaft 24 driven by the double-sided rack 37.

[0099] The second support 2302 is a gantry arranged in a left-right direction, and the second support 2302 is integrally connected to the first support 2301 .

[0100] The extension support 2303 is two horizontal plates extending forward and backward, and the extension support 2303 is integrally connected to the second support 2302, so that the return spring 34 is telescopically adjusted with the extension support 2303 as the fulcrum, supporting the I-shaped lifting rod 33 to move up and down.

[0101] The deflection shaft 24 is rotatably mounted on the load-bearing bracket 23 , and the deflection rod 26 is fixedly mounted on the deflection shaft 24 .

[0102] The voltage sensor 29, the central controller 30 and the driving cylinder 31 are all fixedly mounted on the load-bearing bracket 23, and the voltage sensor 29 is connected in parallel with the copper wire turns 4. The voltage sensor 29 is used to monitor the voltage of the copper wire turns 4 in real time. The central controller 30 synchronously controls the opening and closing of the driving cylinder 31 according to the voltage information fed back by the voltage sensor 29.

[0103] The boost plate 32 is fixedly mounted on the output end of the driving cylinder 31. The driving cylinder 31 drives the boost plate 32 to move onto the placement table 35 to apply intense pressure to the solid sodium azide in the composite capsule 36, so that the solid sodium azide decomposes a large amount of nitrogen.

[0104] The I-shaped lifting rod 33 is slidably mounted on the load-bearing bracket 23 , and the return spring 34 is welded between the load-bearing bracket 23 and the I-shaped lifting rod 33 .

[0105] The placement platform 35 is fixedly installed on the I-shaped lifting rod 33 .

[0106] The composite capsule 36 is fixedly mounted on the placement table 35 , and the composite capsule 36 is fixedly in contact with the pressurizing plate 32 .

[0107] The driven gear 25 is fixedly mounted on the deflection shaft 24, and the double-sided rack 37 is integrally connected to the bottom end of the placement table 35. Under the driving action of the double-sided rack 37, the two deflection shafts 24 are deflected towards or in opposite directions, thereby driving the two conductive plates 22 to move towards or in opposite directions.

[0108] Please refer to the instruction manual for details Figure 3 With attached Figure 4 The upper tank body 101 , the main cavity body 102 and the lower tank body 103 are distributed from top to bottom, and the observation window 104 corresponds to the level of the main cavity body 102 , so that the main cavity body 102 can be observed easily.

[0109] A limiting countersunk hole 105 communicating with the observation window 104 is provided in the reinforcement shell 1 , and a transparent window located in the observation window 104 is installed in the reinforcement shell 1 through the limiting countersunk hole 105 , so as to facilitate observation and management of the main cavity 102 .

[0110] Please refer to the instruction manual for details Figure 7 The copper wire turn 4 is fixedly mounted on the thick-diameter center segment 301 through the center segment 401 , and the end segment 402 corresponds to the thin-diameter end segment 302 .

[0111] The arc-isolating plates 18 are fixedly mounted on the end cap 17 at equal intervals in the circumferential direction. Fig.13 With attached Fig.14 The inner wall of the magnetic arc plate 18 is a flat arc surface structure to match the thin-diameter end section 302, while the outer wall of the magnetic arc plate 18 is an inclined slope structure, which is more convenient to penetrate into the gap between the magnetic core 3 and the copper wire turns 4. Silicon steel sheets are preferred. Although silicon steel sheets can play a magnetic isolation role, they cannot completely isolate the magnetic field. Generally, the silicon content of silicon steel sheets is only 0.5%-4.5%. The higher the silicon content, the better the magnetic isolation effect can be, which is used to interfere with the magnetic force of the magnetic core 3, thereby affecting the effect of the magnetic core 3 on the copper wire turns 4.

[0112] A first traction link 13 is pin-connected between the guide push block 10 and the first limit slider 11 .

[0113] A second traction link 19 is pin-connected between the double-headed swing arm 15 and the moving frame 16 , and the magnetic arc isolation plate 18 is located between the small-diameter end segment 302 and the end line segment 402 .

[0114] Based on this, further explanation:

[0115] A third limit slot 27 extending vertically is formed in the conductive plate 22 , and a third limit slider 28 connected to the deflection rod 26 is slidably mounted in the third limit slot 27 . It is worth noting that the third limit slider 28 is made of insulating silica.

[0116] A guide column 38 which is slidably mounted in the double-sided rack 37 is fixedly installed at the bottom end of the main cavity 102 to provide guide support for the double-sided rack 37 moving up and down, thereby ensuring that the double-sided rack 37 is always meshed and connected with the driven gear 25.

[0117] It should be noted that the specific models and specifications of the voltage sensor 29, the central controller 30 and the driving cylinder 31 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0118] The present invention can be explained by the following operation mode:

[0119] Under the tension of the return spring 34, the conductive plate 22 contacts the conductive terminal 5 and the conductive pin 6, so that the inductor is powered on and operates as a whole;

[0120] When the inductance needs to be adjusted, by applying pressure to the guide push block 10, the guide push block 10 drives the limit clamp 12 to move horizontally through the first traction link 13 and the first limit slider 11;

[0121] By deflecting the damping shaft 14, the damping shaft 14 drives the double-headed swing rod 15 to deflect, and the double-headed swing rod 15 drives the moving frame 16 to move horizontally on the load-bearing rod 2 through the second traction link 19, and the moving frame 16 drives the magnetic arc isolation plate 18 to move through the end cover 17, so that the magnetic arc isolation plate 18 moves corresponding to the small-diameter end section 302, so as to adjust the corresponding range of the magnetic core 3 and the copper wire turn 4;

[0122] The voltage sensor 29 is used to monitor the voltage of the current in the inductor. When the voltage exceeds the warning threshold, the central controller 30 drives the driving cylinder 31 to open, and the driving cylinder 31 drives the booster plate 32 to move vertically downward to squeeze the solid sodium azide in the composite capsule 36, so that the solid sodium azide decomposes a large amount of nitrogen, thereby supporting the composite capsule 36;

[0123] The composite capsule 36 squeezes the placement table 35, so that the placement table 35 drives the double-sided rack 37 to move vertically downward, and the double-sided rack 37 drives the deflection shaft 24 to deflect through the driven gear 25, and the deflection shaft 24 pulls the third limit slider 28 through the deflection pull rod 26, so that the conductive plate 22 drives the second limit slider 21 to move along the second limit long groove 20, thereby disconnecting the conductive terminal 5 and the conductive pin 6;

[0124] When it is needed to be used again, the composite capsule 36 can be replaced.

[0125] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
