Description

Technical Field

[0001] The invention belongs to the technical field of inductors, in particular to a three-phase differential-mode magnetic integrated inductor. Background Art

[0002] As power electronics systems continue to innovate, three-phase differential-mode magnetic integrated inductors are widely used in industrial motor drives, renewable energy generation, uninterruptible power supplies, and other fields due to their advantages in filtering, energy storage, and electromagnetic interference suppression. To ensure stable performance and extend service life, they are often filled with insulating oil. The insulating oil not only provides electrical insulation but also removes heat through its flow, maintaining the normal operating temperature of the inductor.

[0003] However, over the long term, three-phase differential-mode magnetic integrated inductors can produce residue from the insulating oil within them. This residue is caused by aging and decomposition in high-temperature, high-electric-field environments, reacting with oxygen to form organic acids, which further polymerize to form insoluble colloids and asphaltenes. High temperatures also cause thermal decomposition to produce carbides. Furthermore, inductor components wear and corrode, leading to the loss of core particles, aging debris from the coil insulation, and corrosion from metal components.

[0004] These residues seriously affect the components that control the flow of insulating oil, such as oil pumps, valves, pipes, etc. The residues accumulate on the surface of the components and internal channels, increasing the operating resistance and increasing the energy consumption of the oil pump. They also wear key parts, resulting in reduced sealing and operating accuracy of the components, leakage and failure, and destroying the stability and reliability of the insulating oil flow.

[0005] When the control components are damaged, the flow of insulating oil is blocked, the heat dissipation effect is greatly reduced, the heat cannot be taken away from the heating parts in time, the local temperature rises, and the aging and decomposition of the insulating oil is accelerated, forming a vicious cycle. High temperature will also reduce the performance of the inductor, affecting the core performance and coil resistance, and then affecting the inductance value, filtering and electromagnetic compatibility, etc., and even causing safety accidents such as insulation breakdown and fire.

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0046] like Figures 1 to 11 As shown, the three-phase differential-mode magnetic integrated inductor of the present invention includes a transformer part, a mounting part, a driving component, a flow guiding mechanism and a cleaning mechanism.

[0047] The transformer unit includes a carrier substrate 2, a mounting cover 1, and a coil assembly 3. The coil assembly 3 and the mounting cover 1 are both fixedly mounted on the upper end surface of the carrier substrate 2. The coil assembly 3 is located inside the mounting cover 1. The carrier substrate 2, the mounting cover 1, and the coil assembly 3 form a complete three-phase differential-mode magnetic integrated inductor structure. The three-phase differential-mode magnetic integrated inductor can utilize its inductance characteristics to present a higher impedance to high-frequency harmonics in the differential-mode current, making it difficult for high-frequency harmonics to pass through, thereby achieving the purpose of filtering out high-frequency harmonics and making the output current smoother and closer to an ideal sine wave.

[0048] Among them, sealing rubber is provided at the connection part of the supporting substrate 2 and the mounting cover 1. The sealed chamber after the mounting cover 1 and the supporting substrate 2 are assembled is used to inject insulating oil, which is used to achieve the effects of insulation, anti-interference and heat dissipation. In addition, the side wall of the mounting cover 1 is an insulating ceramic structure to facilitate the heat transfer of the insulating oil.

[0049] Among them, an insulating oil replenishing port is provided on the top of the installation cover 1, and a temperature sensor and an information interaction unit are also provided inside the installation cover 1. The temperature sensor is used to monitor the temperature of the insulating oil in real time, and feed back the temperature information to the background terminal through the information interaction unit. The background terminal can thus monitor the temperature of each inductor in real time as one of the evaluation data to prevent inductor overload.

[0050] The mounting portion includes a mounting tube 4 and a guide tube 5. The mounting tube 4 is fixedly mounted on the upper end surface of the carrier substrate 2, wherein the side wall of the mounting tube 4 is provided with a drainage port, and the guide tube 5 is fixedly mounted on the upper end surface of the mounting tube 4. The insulating oil in the inner cavity of the mounting cover 1 is controlled to enter the mounting tube 4 through the guide tube 5, and then be discharged to the inner cavity of the mounting cover 1 through the drainage port on the side wall of the mounting tube 4, thereby disturbing the flow of liquid in the inner cavity of the mounting cover 1, thereby keeping the internal insulating oil in uniform contact with the side wall of the mounting cover 1, thereby keeping the internal heat-generating components evenly dissipated.

[0051] The guide mechanism includes a carrier plate 11, a vortex blade 10 and a filter cone 15. The carrier plate 11 is rotatably arranged in the inner cavity of the mounting cylinder 4, and the vortex blade 10 is fixedly mounted on the upper end of the carrier plate 11. There are multiple vortex blades 10, and the multiple vortex blades 10 are evenly distributed in a ring shape along the middle of the carrier plate 11. The rotation of the vortex blade 10 is controlled, and centrifugal force is used to control the insulating oil to enter the mounting cylinder 4 from the guide cylinder 5, and then be discharged to the inner cavity of the mounting cover 1 through the drain port on the side wall of the mounting cylinder 4.

[0052] The filter cone 15 is fixedly installed in the inner cavity of the guide tube 5 and has an elastic structure. The filter cone 15 is a steel wire mesh with a conical structure, which is used to filter the residue in the insulating oil (the source of the residue: the magnetic core of the inductor wears under long-term electromagnetic action and during the production and manufacturing process of the inductor, if the production environment is not clean, there may be dust, metal debris and other impurities) to prevent the residue of the insulating oil from contacting the vortex blade 10, thereby improving the service life of the vortex blade 10 and maintaining the efficiency of disturbing the fluid flow. The rotation of the supporting plate 11 is controlled by the driving component, which serves as the power source for the rotation of the supporting plate 11.

[0053] The cleaning mechanism includes a scraping blade 14 and an energy storage spring 28. The scraping blade 14 is used to scrape the surface of the filter cone 15, wherein the outer wall of the scraping blade 14 is in contact with the surface of the filter cone 15. By controlling the scraping blade 14 to slide along the radial outer wall of the filter cone 15, the residue attached to the surface of the filter cone 15 is scraped off to maintain the permeability of the filter cone 15.

[0054] The energy storage spring 28 is used to recover the kinetic energy of the vortex blade 10 during rotation, and transfer the kinetic energy to the scraper 14 when the vortex blade 10 stops rotating. Therefore, when the insulating oil stops flowing, the scraper 14 scrapes the outer wall of the filter cone 15, thereby cleaning the filter cone 15 and maintaining the heat exchange effect.

[0055] The driving assembly includes a driving motor 13, a drain cover 8 and a closing plate 12. The closing plate 12 fixes the inner cavity of the mounting cylinder 4 and divides the inner cavity of the mounting cylinder 4 into two spaces through the closing plate 12 for isolating the insulating oil.

[0056] The drive motor 13 is fixedly mounted on the inner wall of the mounting tube 4, and the output shaft of the drive motor 13 passes through the closing plate 12 and is fixedly connected to the bottom surface of the carrier plate 11. The drive motor 13 is a common servo motor, which is used to control the rotation of the carrier plate 11. The control chip inside the drive motor 13 is electrically connected to the information interaction unit. The background terminal sends instructions to the information interaction terminal, and the instructions are transmitted to the control chip of the drive motor 13, thereby controlling the speed of the drive motor 13, which is used to achieve the purpose of the background terminal controlling the rotation of the drive motor 13 through temperature data.

[0057] The drain cover 8 is fixedly mounted on the radial outer wall of the mounting cylinder 4 , and the inner cavity of the drain cover 8 is communicated with the inner cavity of the mounting cylinder 4 . When the supporting plate 11 rotates, the centrifugal force generated thereby discharges the insulating oil inside from the drain cover 8 .

[0058] A mounting bracket 7 is fixedly mounted on the inner wall of the guide tube 5 , a transmission ring 30 is rotatably mounted inside the mounting bracket 7 , a bearing is provided on the radial outer wall of the transmission ring 30 , and the outer ring of the bearing is connected to the mounting bracket 7 .

[0059] The connecting cylinder 22 is fixedly mounted on the axial end of the transmission ring 30 . One end of the scraper 14 is fixedly connected to the radial outer wall of the connecting cylinder 22 . Rotating the transmission ring 30 drives the scraper 14 to rotate, thereby scraping the surface of the filter cone 15 .

[0060] There are multiple scraping blades 14, and multiple scraping blades 14 are evenly arranged in a ring shape along the axis of the connecting cylinder 22 to increase the scraping frequency of the surface of the filter cone 15. At the same time, the evenly arranged scraping blades 14 can make the connecting cylinder 22 subjected to uniform centrifugal force during rotation, thereby maintaining the stability of rotation.

[0061] As a preferred embodiment of the present invention, the side wall of the scraper 14 is inclined, and an elastic strip 17 is fixedly installed on the inner wall of the guide tube 5. When the scraper 14 rotates, one end of the elastic strip 17 is lifted by the inclined setting of the scraper 14. After the scraper 14 and the elastic strip 17 are separated, the elastic strip 17 is reset. At the same time, the outer wall of the scraper 14 is inclined, and the inclined surface can be used to improve the efficiency of scraping and cleaning.

[0062] A knocking ball 18 is fixedly mounted on the other end of the elastic strip 17. When the elastic strip 17 is reset, the knocking ball 18 knocks the filter cone 15, causing the filter cone 15 to vibrate, so that the attached residue falls off.

[0063] A sewage outlet is provided on the radial inner wall of the guide tube 5, and a receiving box 9 is fixedly mounted on the radial outer wall of the guide tube 5. The inner cavity of the receiving box 9 is connected with the inner cavity of the guide tube 5 through the sewage outlet. The residue dropped by the filter cone 15 enters the receiving box 9 through the sewage outlet, and the residue is collected to reduce the residue content in the insulating oil, thereby maintaining the quality of the insulating oil.

[0064] As a preferred embodiment of the present invention, a control gear disc 25 is rotatably provided in the middle of the transmission ring 30 , and the axis of the control gear disc 25 coincides with the axis of the transmission ring 30 .

[0065] One end of the energy storage spring 28 is fixedly connected to the outer wall of the control gear disc 25, and the other end of the energy storage spring 28 is fixedly connected to the inner wall of the transmission ring 30. When the energy storage spring 28 has elastic potential energy, the control gear disc 25 is fixed and the transmission ring 30 is released. At this time, the energy storage spring 28 controls the transmission ring 30 to rotate through elastic force, which serves as the power for the rotation of the scraper blade 14.

[0066] The bottom surface of the control gear plate 25 is fixed with a driven plate 29 via a coupling, and the transmission ring 30 is fixed. At this time, the driven plate 29 is rotated to convert the kinetic energy of the driven plate 29 into the elastic potential energy of the energy storage spring 28.

[0067] A transmission shaft 20 is fixedly installed at the center position of the axial end of the vortex blade 10. When the vortex blade 10 rotates, the transmission shaft 20 is driven to rotate. The transmission shaft 20 passes through the filter cone 15 and is fixedly installed with a driving disk 23. When the transmission shaft 20 rotates, it drives the driving disk 23 to rotate.

[0068] A control block 24 is fixedly mounted on the outer wall of the active disk 23 , and an attraction block 31 is fixedly mounted on the outer wall of the driven disk 29 . The control block 24 and the attraction block 31 attract each other through magnetic force. The control block 24 and the attraction block 31 are magnets that attract each other.

[0069] When the active disk 23 rotates, the driven disk 29 is controlled to rotate by magnetic force, thereby driving the control gear disk 25 to rotate, thereby converting the magnetic force into elastic potential energy of the energy storage spring 28 until the elastic force on the control gear disk 25 is equal to the magnetic force and this state is maintained.

[0070] The inner wall of the driven disk 29 is provided with a rolling friction steel ball 32, and the outer wall of the friction steel ball 32 is in contact with the outer wall of the active disk 23. When the elastic force exerted on the control gear disk 25 is equal to the magnetic force and this state is maintained, the driven disk 29 and the active disk 23 will slide relative to each other. By providing the friction steel ball 32, the friction force is reduced, thereby reducing the heat generated by friction.

[0071] A control gear ring 26 is fixedly mounted on the upper end surface of the transmission ring 30 , and the axes of the control gear ring 26 and the control gear disc 25 coincide with each other.

[0072] A guide frame 27 is fixedly mounted on the upper end surface of the mounting frame 7, and a limit block 34 is slidably mounted on the inner wall of the guide frame 27. The guide frame 27 is located between the control gear ring 26 and the control gear disc 25. When the energy storage spring 28 stores elastic potential energy, the sliding limit block 34 is plugged into the control gear ring 26. At this time, the control gear disc 25 rotates and the control gear ring 26 and the transmission ring 30 are fixed. When the energy storage spring 28 releases the elastic potential energy, the sliding limit block 34 is plugged into the control gear disc 25. At this time, the control gear disc 25 is fixed, and the control gear ring 26 and the transmission ring 30 rotate, driving the scraper 14 to rotate, thereby achieving scraping and cleaning of the filter cone 15.

[0073] As a preferred embodiment of the present invention, an induction disc 6 is mounted on the upper end surface of the mounting frame 7 via an elastic member. The induction disc 6 is located inside the guide tube 5. When the insulating oil flows, the induction disc 6 is affected by the liquid flow and has a tendency to slide inside the guide tube 5.

[0074] A sliding bar 33 is fixedly installed on the bottom surface of the induction disc 6. The sliding bar 33 passes through the guide frame 27 and the limit block 34, and the outer wall of the sliding bar 33 slides in contact with the inner wall of the guide frame 27. When the insulating oil inside the guide cylinder 5 flows, the induction disc 6 drives the sliding bar 33 to slide downward. When the insulating oil stops flowing, the induction disc 6 is driven by the elastic force to reset the sliding bar 33.

[0075] A guide bevel 36 is provided on the side wall of the sliding bar 33, and a guide pin 35 is fixedly installed on the inner wall of the limit block 34, which slides in cooperation with the guide bevel 36. The sliding bar 33 slides up and down, and the sliding direction of the limit block 34 is controlled by the cooperation between the guide bevel 36 and the guide pin 35. When the insulating oil flows, the control limit block 34 is plugged into the control gear ring 26. When the insulating oil stops flowing, the control limit block 34 is plugged into the control gear disc 25. At this time, the energy storage spring 28 releases its elastic potential energy.

[0076] A gate plate 19 for closing the sewage outlet is slidably mounted on the inner wall of the guide tube 5 , and the outer wall of the gate plate 19 is slidably fitted with the inner wall of the guide tube 5 .

[0077] A connecting block 21 is fixedly mounted on the outer wall of the gate plate 19 . The outer wall of the connecting block 21 is elastically connected to the inner wall of the guide cylinder 5 . A spring is provided on the upper end of the connecting block 21 , and the other end of the spring is connected to the inner wall of the guide cylinder 5 .

[0078] A connecting rope 16 is fixedly installed on the outer wall of the induction disc 6, and the other end of the connecting rope 16 is fixedly connected to the outer wall of the connecting block 21. When the insulating oil flows, the induction disc 6 slides down. At this time, the gate plate 19 is elastically closed to close the sewage outlet, preventing the residue from flowing back into the inner cavity of the guide cylinder 5 when the insulating oil flows. When the insulating oil stops flowing, the induction disc 6 slides upward, and the gate plate 19 is pulled to slide by the connecting rope 16, thereby exposing the sewage outlet, so as to keep the sewage outlet conductive when scraping and knocking the filter cone 15.
