Description

Technical Field

[0001] This invention relates to the field of transformer technology, and in particular to a magnetically conductive thermal balance transformer and its control method. Background Technology

[0002] A transformer is a static electrical device that uses the principle of electromagnetic induction to change alternating voltage and current, thereby achieving power transmission and isolation. It is a core component of power systems and electronic equipment. When alternating current passes through a set of coils, it generates a changing magnetic field. This magnetic field induces a current in another set of coils. By adjusting the turns ratio of the two sets of coils, the voltage can be increased or decreased. The transformer utilizes the principle of mutual electromagnetic induction to achieve this through the coordinated operation of various components. It has a compact structure and is compatible with printed circuit board integration.

[0003] Chinese Patent Publication No. CN118899157B discloses a transformer, which includes: an iron core comprising a main column and a side column; a first winding disposed on the main column; and a second winding disposed on the side column, wherein the second winding is connected in parallel with the first winding and is supplied with an excitation current.

[0004] Chinese patent CN104575968A discloses a circuit board transformer, which includes a coil assembly, an iron core assembly and a base; the coil assembly is cylindrical with a through hole in the middle and has a coil area; the iron core assembly includes a lower iron core and an upper iron core.

[0005] The above technical solution has some problems in use. The main magnetic flux is constrained by the iron core, but there will be some leakage flux that is not constrained by the iron core. The leakage flux does not pass through the primary winding and the secondary winding at the same time and will flow to the insulation frame and the isolation shell, which will lead to local overheating and material aging. The traditional method of relying on the isolation shell to shield and prevent leakage flux is not effective.

[0006] If a magnetic sheet is used to guide the leakage flux into the main flux path, and the distribution of the magnetic sheet is adjusted accordingly to avoid eddy currents, when the power input from the external device increases, the amount of magnetic flux flowing in the primary and secondary windings increases. At this time, a single and fixed magnetic sheet cannot fully guide the leakage flux, thereby reducing the guiding efficiency of the leakage flux.

[0007] However, by adjusting the distribution of the magnetic sheets to adapt to different external electrical inputs, eddy currents are more likely to occur in the magnetic sheets as they gather and guide more leakage flux, causing the internal temperature to rise rapidly. The performance of the existing heat dissipation ports cannot meet the requirements for adaptive heat dissipation, and the insulation protection effect on the internal structure of the isolation shell is reduced accordingly, affecting the service life of the magnetic sheets.

[0008] After prolonged use, a small amount of eddy currents may exist inside the magnetic sheet, leading to temperature changes. This can cause the magnetic sheet structure to age or even crack, thus reducing its guiding effect on leakage flux. Magnetic sheets closer to the primary and secondary windings guide more leakage flux, making them more prone to eddy currents and resulting in greater cracking and aging in these areas.

[0009] Meanwhile, the primary winding is completely fixed on the insulating frame, while the secondary winding has an air gap with the primary winding and is fixed to the upper part of the insulating frame and the supporting inclined plate respectively. Therefore, the fixation stability of the secondary winding is not as good as that of the primary winding. After long-term use, the secondary winding is extremely prone to tilting and shifting. The change in the main magnetic flux is not significant, but the leakage flux will change abruptly. As a result, the magnetic sheet cannot accurately conduct the leakage flux again. Moreover, the secondary winding may collide after a long period of tilting and shifting, which will reduce the insulation of both the primary and secondary windings and cause damage to both the primary and secondary windings.

[0010] If the primary and secondary windings are damaged, an inter-turn short circuit will occur inside the primary and secondary windings, preventing the electrical energy from operating normally and potentially leading to safety hazards.

[0011] Therefore, it is necessary to invent a magnetically conductive thermal balance transformer and its control method to solve the above problems. Summary of the Invention

[0012] The purpose of this invention is to provide a magnetically conductive thermal balance transformer and its control method to solve the problems mentioned in the background art.

[0013] To achieve the above objectives, the present invention provides the following technical solution: a magnetically conductive thermal balance transformer, comprising a body assembly, the body assembly including an isolation shell, and further comprising: A guiding component, which is located at the inner bottom of the main body component, includes a magnetic conductive sheet, through which the leakage magnetic flux generated by the main body component is guided back; A connecting component is located at one end of the magnetic sheet. The connecting component drives the guiding component to move. The connecting component includes a movable inclined plate and a supporting inclined plate. When the external power increases, the movable inclined plate moves closer to the supporting inclined plate and reduces the gap between multiple magnetic sheets, thereby increasing the leakage magnetic flux guided back by the magnetic sheets. When the body assembly tilts to one side, the movable inclined plate at the corresponding position moves closer to the supporting inclined plate and reduces the gap between the magnetic sheets. The connector, which is slidably disposed on the inner top of the isolation housing, moves to its maximum value away from the supporting inclined plate and disconnects the connector when a short circuit occurs inside the body assembly.

[0014] Preferably, the body component further includes: The base, which is fixedly installed with external equipment, is used to connect and support the transformer equipment; An insulating frame, mounted on a base, is used for electrical isolation between live parts; The iron core is inserted into the interior of the insulating frame, and the upper and lower parts are joined together to form a closed magnetic circuit as the main magnetic flux path. One end of the magnetic conductive sheet is vertically slidably connected to the lower side of the iron core.

[0015] Preferably, the body component further includes: The primary winding is sleeved on the surface of the insulating frame and has an insulating layer on the surface. The primary winding is connected to the power supply side to receive electrical energy. The secondary winding is sleeved outside the primary winding and has an insulating layer on its surface. The bottom of the connector is fixedly electrically connected to the top of the secondary winding. The secondary winding senses the electrical energy of the primary winding and connects to the load side to output electrical energy. The leakage magnetic flux generated by the primary winding and the secondary winding is guided to the main magnetic flux on the iron core side by the magnetic sheet. The port is installed on the top of the isolation enclosure, and the top of the connector is electrically connected to the port to enable the secondary winding to output electrical energy.

[0016] Preferably, the guiding component includes: The insulating pad, which is installed between the magnetic sheets, is used to increase the resistance of the eddy current path in the magnetic sheets, thereby reducing the eddy current; The magnetic conductive sheet is installed at the bottom inside the isolation shell, with multiple magnetic conductive sheets on the same side concentrated in the middle of the isolation shell and dispersed on both sides.

[0017] Preferably, the guiding component further includes: A shielding shell, which is installed at the end of the magnetic sheet, is used to isolate the magnetic sheet inside the shielding shell; The drive unit is installed inside the shielding shell, and the output end of the drive unit is fixedly connected to the magnetic plate on the side, which is used to drive the magnetic plate to move and adjust the gap between the magnetic plates.

[0018] Preferably, the connection component includes: The chuck is fixedly installed at the output end of the guide component, and the guide component drives the chuck to move. The connector has a bottom groove that engages with the protrusion of the chuck. The output end of the drive device drives the magnetic sheet to move, which in turn drives the connector to move.

[0019] Preferably, one end of the movable inclined plate is fixedly connected to one end of the connector, and a heat dissipation vent is provided on the side of the isolation shell for ventilation and heat dissipation inside the isolation shell. The side of the movable inclined plate is slidably connected to the heat dissipation vent, and the movable inclined plate moves with the movement of the connector. The inclined surface of the supporting inclined plate is slidably engaged with the inclined surface of the movable inclined plate, and the supporting inclined plate moves longitudinally with the lateral movement of the movable inclined plate.

[0020] A control method for a magnetically conductive thermal balance transformer, the control method utilizing the magnetically conductive thermal balance transformer for control, the control method comprising the following steps: S1. The main magnetic flux generated by the primary winding links with the secondary winding and performs electro-magnetic-electric conversion of electrical energy; S2, where the leakage flux is guided by the magnetic sheet to the main magnetic flux path inside the iron core; S3. When the external voltage increases, the connecting component drives the magnetic sheet to gather towards the center and the opening of the heat dissipation port increases. S4. When the magnetic sheet fails, the connecting component drives the magnetic sheet to gather in the middle while the opening of the heat dissipation port remains unchanged. S5. When the secondary winding is tilted, the connecting component in the tilt direction of the secondary winding drives the magnetic sheet to gather in the middle and the opening of the heat dissipation port increases, and the secondary winding moves in the opposite direction to correct it. S6. When the primary winding and the secondary winding are short-circuited, the connecting component drives the magnetic sheet to move to the maximum distance on both sides, and the secondary winding drives the connector to move downward to the maximum distance and disconnects the electrical connection with the connector to perform power-off protection.

[0021] The technical effects and advantages of this invention are as follows: 1. In this invention, the leakage flux is guided into the main flux path by the magnetic conductive sheet, thereby fully collecting the leakage flux, reducing the outward leakage flux and improving the flux guiding efficiency, suppressing the impact of the leakage flux of the primary and secondary windings on the insulation frame and isolation shell, reducing the risk of local heating, and extending the equipment life.

[0022] 2. In this invention, the heat dissipation port and the magnetic conductive sheet are adaptively adjusted to ensure full utilization of the magnetic conductive sheet, while also fully guiding the changing leakage magnetic flux. In addition, the adaptive heat dissipation effect keeps the internal structure of the isolation shell stable.

[0023] 3. In this invention, the magnetic conductive sheet is gathered towards the center to compensate for the failure of leakage magnetic flux caused by aging and cracking of the magnetic conductive sheet. Moreover, the magnetic conductive sheet has a stable heat dissipation effect when guiding the same leakage magnetic flux, ensuring that the leakage magnetic flux can be fully guided. The magnetic conductive sheet is located at the optimal position for guiding the leakage magnetic flux.

[0024] 4. In this invention, for the tilting deviation of the secondary winding, the magnetic guide sheet is precisely changed to guide the leakage flux, and the secondary winding is corrected in time to avoid collisions caused by long-term tilting deviation of the secondary winding, thus ensuring the stability of the primary and secondary windings during the conduction process.

[0025] 5. In this invention, when there is a short circuit between turns in the primary winding and the secondary winding, the power is cut off in time by disconnecting the connector, so as to avoid safety hazards caused by the short circuit between turns and ensure that the primary winding and the secondary winding are protected by timely and stable circuit disconnection in case of unexpected situations.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1 In a magnetically conductive thermal balance transformer, the main magnetic flux is constrained by the iron core 103 along the path of lowest magnetic reluctance, i.e., inside the iron core 103. However, some magnetic flux leaks out of the iron core 103. This leakage flux does not simultaneously pass through the primary winding 104 and the secondary winding 105, and it flows to the insulation frame 102 and the isolation shell 106, causing localized overheating and material aging. Traditional methods relying solely on the isolation shell 106 for shielding and preventing leakage flux are ineffective. If the leakage flux is guided into the main magnetic flux path by the magnetically conductive sheet 301, and the distribution of the magnetically conductive sheet 301 is adjusted accordingly to avoid eddy currents, the magnetic flux flowing through the primary winding 104 and the secondary winding 105 will increase when the input power from external equipment increases. In addition, the single and fixed magnetic sheet 301 cannot fully guide the leakage flux, resulting in a significant reduction in the guiding efficiency of the leakage flux. By adjusting the distribution of the magnetic sheets 301 to adapt to different external electrical inputs, the magnetic sheets 301 are more prone to eddy currents during the process of gathering to guide more leakage flux, causing the internal temperature to rise rapidly. The performance of the existing heat dissipation vent 2 cannot meet the requirements. Directly opening a larger heat dissipation vent 2 may cause excessive cold air to cause water droplet condensation, thereby damaging the internal structure of the isolation shell 106 and correspondingly reducing the insulation protection effect on the internal structure of the isolation shell 106. On the other hand, opening a smaller heat dissipation vent 2 may not dissipate heat in time, which may pose a safety hazard and affect the service life of the magnetic sheet 301.

[0030] This invention provides, for example Figures 1 to 11 The illustrated magnetically permeable thermal balance transformer includes: a body assembly 1, which includes an isolation shell 106 with heat dissipation vents 2 on its side for ventilation and heat dissipation; a base 101 fixedly installed with external equipment for connecting and supporting the transformer; an insulating frame 102 mounted on the base 101 for electrical isolation between energized components; the insulating frame 102 separating the core 103 from the primary winding 104 and the secondary winding 105 so that the core 103 is not energized; the core 103 is inserted into the interior of the insulating frame 102, and the upper and lower parts are joined to form a closed magnetic circuit as the main magnetic flux path, enhancing the transmission of electrical energy in the electro-magnetic-electric conversion process; the core 103 is made of a high-permeability material to achieve efficient transmission of electrical energy in the electro-magnetic-electric conversion process.

[0031] The primary winding 104 is sleeved on the surface of the insulating frame 102 and has an insulating layer on its surface. The primary winding 104 is connected to the power supply side to receive electrical energy. The secondary winding 105 is sleeved on the outside of the primary winding 104 and has an insulating layer on its surface. The secondary winding 105 senses the electrical energy of the primary winding 104 and is connected to the load side to output electrical energy. The leakage magnetic flux generated by the primary winding 104 and the secondary winding 105 is guided by the magnetic sheet 301 to the main magnetic flux on the iron core 103 side.

[0032] The guiding component 3, located at the inner bottom of the main body component 1, includes a magnetic conductive sheet 301. One end of the magnetic conductive sheet 301 is vertically slidably connected to the lower side of the iron core 103, meaning the magnetic conductive sheet 301 and the iron core 103 are in contact and conduct leakage magnetic flux. The magnetic conductive sheet 301 can slide on the side wall of the iron core 103, guiding the leakage magnetic flux generated by the main body component 1 back to the main magnetic flux path of the iron core 103. The guiding component 3 includes an isolation pad 302, which is an elastic structure. When squeezed by the magnetic conductive sheets 301 on both sides, the isolation pad elastically contracts, allowing the leakage magnetic flux generated by the main body component 1 to flow back to the main magnetic flux path of the iron core 103. To adjust the gap between two adjacent magnetic sheets 301, it is installed between the magnetic sheets 301 to increase the resistance of the eddy current path in the magnetic sheets 301 and reduce the eddy current. The magnetic sheets 301 are installed at the bottom of the inner side of the isolation shell 106. Multiple magnetic sheets 301 on the same side are concentrated in the middle position inside the isolation shell 106 and dispersed on both sides. That is, the magnetic sheets 301 in the middle position are more concentrated, and the magnetic sheets 301 at both ends are more dispersed, so as to accommodate the larger magnetic flux in the middle position near the primary winding 104 and the secondary winding 105.

[0033] A shielding shell 303 is installed at the end of the magnetic sheet 301 to isolate the magnetic sheet 301 inside the shielding shell 303. The magnetic sheet 301 moves towards the center and converges, while some of the magnetic sheets 301 inside the shielding shell 303 move out of the shielding shell 303. A driving device 304 is installed inside the shielding shell 303, and the output end of the driving device 304 is fixedly connected to the side end of the magnetic sheet 301 to drive the magnetic sheet 301 to move and adjust the gap between the magnetic sheets 301.

[0034] The connecting component 4 is located at one end of the magnetic sheet 301. The connecting component 4 drives the guiding component 3 to move. The connecting component 4 includes a movable inclined plate 403 and a supporting inclined plate 404. When the external power increases, the gap between the magnetic sheets 301 is adjusted according to the amount of leakage flux. The isolation pad 302 between the magnetic sheets 301 is compressed, which reduces the gap between the magnetic sheets 301. The magnetic sheets 301 closer to the primary winding 104 and the secondary winding 105 are increased, thereby fully guiding the increased leakage flux.

[0035] The connecting component 4 includes a chuck 401, which is fixedly installed at the output end of the guiding component 3, and the guiding component 3 drives the chuck 401 to move; a connector 402, the bottom groove of which engages with the protrusion of the chuck 401, so that the driving device 304 drives the magnetic sheet 301 to move through the chuck 401 and simultaneously drives the connector 402 to move; one end of the movable inclined plate 403 is fixedly connected to one end of the connector 402, and the side of the movable inclined plate 403 is slidably connected to the heat dissipation vent 2, and the movable inclined plate 403 moves with the movement of the connector 402; a supporting inclined plate 40 4. The top is fixedly connected to the bottom of the secondary winding 105. The inclined surface of the support plate 404 is slidably engaged with the inclined surface of the movable plate 403. The support plate 404 moves longitudinally as the movable plate 403 moves laterally. The movable plate 403 moves closer to the support plate 404, causing the support plate 404 to move upward. This pushes the secondary winding 105 upward. The primary winding 104 and the secondary winding 105 are vertically and horizontally misaligned, allowing the heat between the primary winding 104 and the secondary winding 105 to be better discharged, ensuring better heat dissipation.

[0036] In summary, during use, the base 101 is installed on an external electrical device, and an excitation current is generated in the primary winding 104. After the excitation current flows through the primary winding 104, according to Ampere's law, the current will generate magnetic lines of force in the iron core 103 surrounding the primary winding 104. The iron core 103 constrains the magnetic lines of force to form an efficient magnetic flux path. Due to the excellent magnetic permeability of the iron core 103, most of the magnetic flux generated by the primary winding 104 will be constrained inside the iron core 103 and pass through the secondary winding 105 located in the same magnetic circuit. After the magnetic flux passes through the secondary winding 105, according to Faraday's law... According to the law of electromagnetic induction, electrical energy is induced at both ends of the secondary winding 105. The secondary winding 105 is connected to the load through the connector 5, forming a complete circuit. Electrical energy is transferred from the input end of the primary winding 104 to the output end of the secondary winding 105 through the medium of the magnetic field, realizing voltage transformation. That is, the voltage value is determined by the turns ratio of the primary winding 104 and the secondary winding 105. The primary winding 104 and the secondary winding 105 are internally charged, but each has its own insulation layer to prevent short circuit. The insulation frame 102 separates the iron core 103 from the primary winding 104 and the secondary winding 105 so that the iron core 103 is not charged.

[0037] Since the iron core 103 is made of a high-permeability material, the magnetic lines of force will preferentially close along the iron core 103, thus passing through the secondary winding 105 with almost no loss. This allows the main magnetic flux generated by the primary winding 104 to link with the secondary winding 105 to the maximum extent, realizing the efficient transmission of electrical energy in the electro-magnetic-electric conversion process. Most of the leakage magnetic flux is perpendicular to the direction of the main magnetic flux in the iron core 103, and mainly exists in the air gaps between the primary winding 104 and the secondary winding 105, and between the primary winding 104 and the secondary winding 105 and the iron core 103. The magnetic sheet 301 forms a curved structure, and the leakage magnetic flux is guided to the side of the iron core 103 under the action of the magnetic sheet 301. The upper part of the magnetic sheet 301 forms an inclined surface to fully collect the leakage magnetic flux. The thickness of the sensing part of the magnetic sheet 301 gradually decreases towards the iron core 103, and the leakage magnetic flux is concentrated and flows back into the main magnetic flux path inside the iron core 103 to reduce the outward leakage magnetic flux and improve the magnetic flux guiding efficiency.

[0038] The magnetic sheet 301 guides leakage flux, thereby effectively suppressing the impact of leakage flux from the primary winding 104 and secondary winding 105 on the insulation frame 102 and the isolation shell 106, reducing the risk of localized heating, extending equipment life, and improving the stability of the primary winding 104 and secondary winding 105 and optimizing the insulation distance, thus enhancing overall operational reliability. However, like the iron core 103, the magnetic sheet 301 is also a conductor, and in an alternating magnetic field, it will induce vortex currents, causing the iron core 103 and the magnetic sheet 301 to heat up. The iron core 103 is usually made of thin silicon steel sheets. Stacking the sheets together insulates them from each other, cutting off the path of eddy currents to reduce losses. The insulating pad 302 divides the magnetic sheets 301 into multiple groups, thereby cutting off eddy currents to avoid heat generation and reduce magnetic flux loss. The magnetic sheets 301 in the middle position are more concentrated, while those at both ends are more dispersed. This is to accommodate the larger magnetic flux in the middle position near the primary winding 104 and secondary winding 105, while the magnetic flux at both ends gradually decreases. This ensures full utilization of the magnetic sheets 301 and prevents overheating and losses due to excessive concentration of the magnetic sheets 301.

[0039] The heat dissipation vents 2 on the side wall of the isolation shell 106 dissipate heat from the internal structure of the isolation shell 106. External cold air passes through the heat dissipation vents 2 and through the bottom magnetic conductive sheet 301, and then through the air gap between the primary winding 104 and the secondary winding 105, carrying away the internal heat of the isolation shell 106 from bottom to top and being discharged from the top of the isolation shell 106. This ensures efficient and precise heat dissipation of the isolation shell 106 and avoids damage or even safety hazards caused by excessive internal temperature of the isolation shell 106.

[0040] When the input power of external devices increases, the magnetic flux flowing in the primary winding 104 and the secondary winding 105 increases, and the main magnetic flux and leakage magnetic flux both increase accordingly. This causes the control system to control the start-up drive device 304, which drives the magnetic conductive plates 301 connected to the output end to move closer to each other through the drive device 304 inside the shielding shell 303. Since some of the magnetic conductive plates 301 at both ends are placed inside the shielding shell 303 to shield the magnetic flux for backup, the magnetic conductive plates 301 move towards the middle position. Meanwhile, some of the magnetic conductive plates 301 inside the shielding shell 303 move out of the shielding shell 303, and the elastic isolation pads 302 between the magnetic conductive plates 301 are compressed, reducing the gap between the magnetic conductive plates 301. The number of magnetic conductive plates 301 close to the primary winding 104 and the secondary winding 105 increases, thereby fully guiding the increased leakage magnetic flux and allowing the leakage magnetic flux to flow back to the main magnetic flux path through the magnetic conductive plates 301, so as to better guide the leakage magnetic flux under different conditions.

[0041] Simultaneously, the drive device 304 synchronously drives the chuck 401 connected to the output end to move. Since the protruding part of the chuck 401 engages with the groove at the bottom of the connector 402, the movement of the chuck 401 drives the connector 402 and the movable inclined plate 403 to move. The movable inclined plate 403 moves towards the supporting inclined plate 404. Due to the sliding engagement of the inclined surfaces of the movable inclined plate 403 and the supporting inclined plate 404, the movable inclined plate 403 moves closer to the supporting inclined plate 404, causing the supporting inclined plate 404 to move upwards. This, in turn, pushes the secondary winding 10 upwards. 5. The vibration damping support of the secondary winding 105 is more stable, and the primary winding 104 and the secondary winding 105 are vertically and horizontally misaligned, so that the heat between the primary winding 104 and the secondary winding 105 can be better discharged, ensuring better heat dissipation. In addition, the moving inclined plate 403 reduces the obstruction area of ​​the heat dissipation port 2, so that the opening area of ​​the heat dissipation port 2 can be increased. As the magnetic flux increases and the heat caused by the dense magnetic sheet 301 increases, the heat can be better discharged through the heat dissipation port 2, so that the internal structure of the isolation shell 106 remains stable.

[0042] Example 2 Based on the above embodiments, a small amount of eddy currents may exist inside the magnetic conductive sheet 301, which may cause aging during temperature changes. Over time, the magnetic conductive sheet 301 is prone to cracking, and both cracking and aging cause the magnetic conductive sheet 301 to fail, thus affecting its guiding effect on leakage flux. The magnetic conductive sheets 301 closer to the primary winding 104 and secondary winding 105 guide more leakage flux and are more prone to eddy currents, resulting in greater cracking and aging. At the same time, the primary winding 104 is completely fixed to the insulating frame 102, while the secondary winding 105 has an air gap with the primary winding 104 and is fixed to the upper part of the insulating frame 102 and the supporting inclined plate 404 respectively. Therefore, the secondary winding 105 is more stable than the primary winding 104. The stability of winding 4 is poor. After long-term use, the secondary winding 105 is extremely prone to tilting and shifting. The main magnetic flux changes little, but the leakage flux changes abruptly. The magnetic sheet 301 can no longer accurately conduct the leakage flux. Furthermore, the long-term tilting and shifting of the secondary winding 105 may cause collisions, which reduces the insulation of both the primary winding 104 and the secondary winding 105, resulting in damage to both windings. If the primary winding 104 and the secondary winding 105 are damaged, an inter-turn short circuit will occur inside them. Electrical energy cannot operate normally in the primary winding 104 and the secondary winding 105. The inter-turn short circuit will cause a huge temperature change, which can easily lead to safety hazards.

[0043] To solve the above problems, a magnetically conductive thermal balance transformer further includes a connector 5, which is slidably disposed on the inner top of the isolation housing 106 for outputting electrical energy. The movable inclined plate 403 moves away from the supporting inclined plate 404 to its maximum value and disconnects the connector 5. The port 107 is installed on the top of the isolation housing 106. The bottom of the connector 5 is electrically connected to the top of the secondary winding 105. The top of the connector 5 is elastically connected to the bottom of the port 107, so that the secondary winding 105 outputs electrical energy to the port 107 through the connector 5. The connector 5 is a spring conductive structure. When the secondary winding 105 moves up and down within a certain range, it drives the connector 5 to move up and down without disconnecting the electrical connection with the port 107. When the secondary winding 105 moves beyond a certain range, the connector 5 disconnects from the port 107.

[0044] The secondary winding 105 causes the connector 5 to move downward beyond a certain range, and the port 107 disconnects from the connector 5. When the main body assembly 1 is short-circuited, the drive device 304 located on both sides of the secondary winding 105 drives the chuck 401 to move. The chuck 401 drives the connector 402 and the movable inclined plate 403 to move. The movable inclined plate 403 moves away from the supporting inclined plate 404 to its maximum value. The connector 5 at the top of the secondary winding 105 moves downward with the secondary winding 105 to its maximum value, so that the connector 5 is disconnected from the port 107 and finally disconnected from the port 107, thus making the secondary winding 105 open circuit. Electrical energy is transferred from the input end of the primary winding 104 to the output end of the secondary winding 105 through the medium of the magnetic field. The magnetic lines of force will preferentially close along the iron core 103, thus passing through the secondary winding 105 with almost no loss. This allows the main magnetic flux generated by the primary winding 104 to link with the secondary winding 105 to the maximum extent.

[0045] In summary, some ports 107 connect the primary winding 104 to external electrical equipment via lines, allowing electrical energy input from the external electrical equipment to reach the primary winding 104 through ports 107. Other ports 107 connect the external electrical equipment to the secondary winding 105, allowing the secondary winding 105 to output electrical energy to the external electrical equipment through connector 5 and ports 107.

[0046] When the magnetic sheet 301 fails due to aging and cracking, and the external input power remains unchanged but the output power fluctuates and decreases, the drive device 304 drives the magnetic sheet 301 to gather towards the center. Part of the magnetic sheet 301 inside the shielding shell 303 moves out to guide leakage flux. The elastic isolation pads 302 between the magnetic sheets 301 are compressed, reducing the gap between them. This compensates for the leakage flux failure caused by the aging and cracking of the magnetic sheet 301. The magnetic sheet 301 gradually gathers towards the center, reaching a certain position. As the number of aging and cracking magnetic sheets 301 increases, the position where the magnetic sheets 301 gather towards the center becomes closer. Then, the drive device 304 drives the magnetic sheet 301 to disperse in opposite directions until the magnetic sheet 301 reaches the optimal position for guiding leakage flux.

[0047] Simultaneously, as the driving device 304 drives the magnetic sheet 301 to converge towards the center, the driving device 304 moves, and the chuck 401 drives the connecting piece 402 and the movable inclined plate 403 to move. As a result, the movable inclined plate 403 pushes the supporting inclined plate 404 to move upward. The movable inclined plate 403 pushes the supporting inclined plate 404 to move upward to the maximum position. At this time, the driving device 304 drives the magnetic sheet 301 to continue converging towards the center, but the supporting inclined plate 404 can no longer move upward after moving to the maximum position. The connecting piece 402 and the movable inclined plate 403 also stop moving under the limiting effect of the supporting inclined plate 404. The driving device 304 drives the chuck 401 to continue moving. Since the protrusion of the chuck 401 can retract, the chuck 401 continues to move forward in the groove below the connecting piece 402, so that the protrusion of the chuck 401 can engage with the grooves in the connecting piece 402 that are relatively closer to the sides. The forward distance of the chuck 401 at the bottom of the connecting piece 402 is related to the distance of the supplementary magnetic sheet 301 due to aging and cracking.

[0048] Subsequently, as the magnetic conductive sheet 301 moves in opposite directions to both ends, the connector 402 and the movable inclined plate 403 also move in opposite directions. Since the chuck 401 protrudes and engages in the groove in front of the connector 402, during the process of replenishing the magnetic conductive sheet 301 which has failed to guide some leakage magnetic flux due to aging and cracking, the magnetic conductive sheet 301 is more concentrated in replenishing the magnetic conductive sheet 301 that has failed to guide magnetic flux. Compared with guiding the same leakage magnetic flux before the magnetic conductive sheet 301 has aging and cracked, the opening and heat dissipation effect of the heat dissipation port 2 have not changed, ensuring that the heat dissipation effect of the magnetic conductive sheet 301 is more stable when guiding the same leakage magnetic flux, and thus the process of the magnetic conductive sheet 301 guiding leakage magnetic flux is more stable.

[0049] Furthermore, during the movement of the movable inclined plate 403, the secondary winding 105 is driven to move upward through the supporting inclined plate 404. The secondary winding 105 drives the connector 5 to move upward and maintains constant pressure contact with the port 107. With the help of the spring conductive structure of the connector 5 itself, the up and down movement of the secondary winding 105 will not affect its normal power supply.

[0050] When the secondary winding 105 tilts relative to the primary winding 104, the secondary winding 105 moves away from the primary winding 104 in the direction of its tilt, resulting in an increase in leakage flux in that direction. At this time, the drive device 304 in the direction of the secondary winding 105's tilt causes the magnetic conductor 301 to move, converging towards the center. This increases the number of magnetic conductors 301 near the primary winding 104 and the secondary winding 105, thus effectively guiding the increased leakage flux and reducing its leakage. The magnetic flux through the magnetic sheet 301 is fully returned to the main magnetic flux path, and the driving device 304 drives the chuck 401 to move. The chuck 401 drives the connector 402 and the movable inclined plate 403 to move. The movable inclined plate 403 moves towards the support inclined plate 404. The movable inclined plate 403 moves closer to the support inclined plate 404, causing the support inclined plate 404 to move upward. The support inclined plate 404 pushes the secondary winding 105 upward for support and correction. The movement of the movable inclined plate 403 reduces the obstruction area of ​​the heat dissipation port 2, and the adjustment of the heat dissipation port 2 ensures better heat dissipation.

[0051] Simultaneously, the secondary winding 105 in the opposite direction of its tilt shift moves closer to the primary winding 104, thus reducing the leakage flux in the opposite direction of the secondary winding 105's tilt shift. At this time, the drive device 304 in the opposite direction of the secondary winding 105's tilt shift drives the magnetic guide plate 301 to move. The magnetic guide plate 301 moves and disperses to both ends, reducing the number of magnetic guide plates 301 close to the primary winding 104 and the secondary winding 105. This adaptively guides the reduced leakage flux, allowing it to flow precisely back to the main flux path via the magnetic guide plate 301. Furthermore, the drive device 304 drives the chuck 401 to move, and the chuck 401 drives... The connector 402 and the movable inclined plate 403 move, and the movable inclined plate 403 moves away from the supporting inclined plate 404. The movable inclined plate 403 moves away from the supporting inclined plate 404, causing the supporting inclined plate 404 to move downward. As a result, the secondary winding 105 moves downward with the supporting inclined plate 404. Since the support height in the direction of the tilt offset of the secondary winding 105 is greater than the opposite direction of the tilt offset of the secondary winding 105, the two sets of supporting inclined plates 404 cooperate to support and correct the secondary winding 105. In addition, the movement of the movable inclined plate 403 increases the blocking area of ​​the heat dissipation vent 2, and the heat dissipation vent 2 is adaptively adjusted to ensure that the internal structure of the isolation shell 106 remains stable.

[0052] When a short circuit occurs between the turns of the primary winding 104 and the secondary winding 105, the drive devices 304 located on both sides of the secondary winding 105 drive the chuck 401 to move away from each other to its maximum value. The chuck 401 then drives the connector 402 and the movable ramp 403 to move away from each other to their maximum value. Specifically, the movable ramp 403 moves away from the supporting ramp 404 to its maximum value. As the movable ramp 403 moves away from the supporting ramp 404, the supporting ramp 404 moves downward to its maximum value. Consequently, the secondary winding 105 moves downward with the supporting ramp 404. Both sets of supporting ramps 404 and the secondary winding 105 move downward simultaneously. At this time, the connector 5 at the top of the secondary winding 105 moves downward with the secondary winding 105 to its maximum value. The connector 5 then disconnects from the port 107, thus creating an open circuit in the secondary winding 105. This protects the stable energization of the primary winding 104 and the secondary winding 105, thereby avoiding safety hazards caused by the short circuit between turns.

[0053] Example 3 A control method for a magnetically conductive thermal balance transformer, the control method utilizing the magnetically conductive thermal balance transformer, and the control method includes the following steps: S1. The main magnetic flux generated by the primary winding 104 links with the secondary winding 105 and performs an electro-magnetic-electric conversion of electrical energy. Electrical energy is transferred from the input terminal of the primary winding 104 to the output terminal of the secondary winding 105 through the medium of the magnetic field, realizing voltage transformation. That is, the voltage value is determined by the turns ratio of the primary winding 104 and the secondary winding 105.

[0054] S2, wherein the leakage flux is guided by the magnetic sheet 301 to the main magnetic flux path inside the iron core 103. The upper part of the magnetic sheet 301 forms an inclined surface, thereby fully collecting the leakage flux. As a result, the thickness of the sensing part of the magnetic sheet 301 gradually decreases towards the iron core 103, and the leakage flux is concentrated and flows back into the main magnetic flux path inside the iron core 103.

[0055] S3. When the external voltage increases, the connecting component 4 drives the magnetic sheet 301 to gather towards the center and the opening of the heat dissipation port 2 increases. The magnetic sheet 301 moves towards the center position and gathers, which reduces the gap between the magnetic sheets 301. The magnetic sheets 301 close to the primary winding 104 and the secondary winding 105 increase, thereby fully guiding the increased leakage flux. As the magnetic flux increases and the heat caused by the dense magnetic sheets 301 increases, the heat can be better discharged through the heat dissipation port 2 to the isolation shell 106.

[0056] S4. When the magnetic sheet 301 partially fails, the connecting component 4 drives the magnetic sheet 301 to gather towards the center while the opening of the heat dissipation port 2 remains unchanged. The magnetic sheet 301 gradually gathers towards the center and reaches a certain position. As the number of magnetic sheets 301 that have aged and cracked increases, the magnetic sheets 301 gather towards the center and the position becomes closer. Then, the driving device 304 drives the magnetic sheet 301 to disperse in the opposite direction to both ends until the magnetic sheet 301 reaches the optimal position for guiding the leakage flux. Compared with guiding the same leakage flux before the magnetic sheet 301 has aged and cracked, the opening of the heat dissipation port 2 and the heat dissipation effect have not changed.

[0057] S5. When the secondary winding 105 is tilted, the connecting component 4 in the tilt direction of the secondary winding 105 drives the magnetic sheet 301 to gather in the middle and the opening of the heat dissipation port 2 increases. The secondary winding 105 moves in the opposite direction to correct itself. At the same time, the connecting component 4 corrects the secondary winding 105 and fully guides the increased leakage flux. The leakage flux flows back to the main flux path through the magnetic sheet 301. The two sets of supporting inclined plates 404 cooperate to support and correct the secondary winding 105. The heat dissipation port 2 is adjusted adaptively to ensure that the internal structure of the isolation shell 106 remains stable.

[0058] S6. When the primary winding 104 and the secondary winding 105 are short-circuited, the connecting component 4 drives the magnetic sheet 301 to move to the maximum distance on both sides, and the secondary winding 105 drives the connector 5 to move downward to the maximum distance and disconnects the power connection with the port 107 to perform power-off protection, thereby making the secondary winding 105 open-circuit, thus avoiding the safety hazards caused by the inter-turn short circuit.
