Description

Technical Field

[0001] This application relates to the field of transformer technology, and in particular to a toroidal transformer structure. Background Technology

[0002] Toroidal transformers are a major type of electronic transformer and are widely used in household appliances and other electronic devices with high technical requirements. Their main uses are as power transformers and isolation transformers. They have advantages such as high electrical efficiency, low vibration and noise, low operating temperature, and easy installation.

[0003] Toroidal transformers are widely used in power transmission and electronic equipment due to their closed magnetic circuit structure. However, traditional silicon steel cores have inherent defects such as high hysteresis loss and large eddy current loss. With the commercial application of amorphous alloy materials, their high permeability and low coercivity characteristics provide a new way to improve transformer efficiency.

[0004] Existing toroidal transformers typically use an integral core structure as the main output structure. However, during long-term operation, as the core structure continues to operate, internal damage is inevitable. When performing maintenance, the entire core structure needs to be replaced, resulting in high maintenance costs. Furthermore, the integral core structure involves many installation steps, and it is inconvenient for people to operate it during disassembly and replacement, which is not conducive to maintenance. Utility Model Content

[0005] The purpose of this application is to address the problems in the prior art where, during long-term operation, the core structure inevitably suffers internal damage due to continuous transmission. Repairing this damage requires replacing the entire core structure, leading to high maintenance costs. Furthermore, the integral core structure involves numerous installation steps, making disassembly and replacement inconvenient and hindering maintenance. This application provides a toroidal transformer structure.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A toroidal transformer structure includes a mounting base plate, a heat sink fixedly connected to the top of the mounting base plate, an annular shell fixedly connected to the top of the heat sink, and the top of the heat sink communicating with the annular shell. A cover is installed on the top of the annular shell, and multiple detachable iron cores are installed inside the annular shell. A fixing member is provided on the cover, and the annular shell and the cover are fixedly connected by the fixing member.

[0007] By adopting the above technical solution, multiple iron cores are detachably connected inside the annular shell. When it is necessary to replace the iron core, the fixing parts can be manually operated to release the fixing parts from the cover, and then the cover can be pulled out from the annular shell to open the annular shell. After that, the iron core can be manually pulled out from the annular shell to complete the disassembly and replacement of the iron core. This realizes the modular installation of the iron core, improves the maintenance efficiency of the transformer, greatly shortens the downtime of the transformer, and improves the practicality of the transformer.

[0008] Furthermore, multiple partition plates are fixedly connected to the inner side of the annular shell, and an installation chamber is formed between two partition plates. The iron core is slidably installed inside the installation chamber.

[0009] By adopting the above technical solution, the iron core can be installed by inserting it into the installation chamber.

[0010] Furthermore, the partition plate has grooves on both sides, and the iron core has sliders fixedly connected to both sides, with the sliders slidably installed inside the grooves.

[0011] By adopting the above technical solution, the iron core can be slidably inserted by sliding the slider in the groove.

[0012] Furthermore, the cover has a perforation in the middle, and multiple positioning rods are fixedly connected to the bottom of the cover.

[0013] By adopting the above technical solution, the fastener can be easily inserted and fixed through the perforation.

[0014] Furthermore, the top of the annular shell is provided with multiple positioning holes, and the positioning rod is inserted into the positioning holes.

[0015] By adopting the above technical solution, the positioning and installation of the cover can be achieved by inserting multiple positioning rods into the positioning holes.

[0016] Furthermore, the fastener includes a fixing pin that passes through and is connected inside the perforation. A baffle is fixedly connected to the top of the fixing pin. A threaded hole is opened on the top of the heat sink. The bottom of the fixing pin is threadedly connected to the threaded hole.

[0017] By adopting the above technical solution, the cap can be fixed to the annular shell by connecting the fixing pin with the threaded hole.

[0018] Furthermore, multiple fans are fixedly connected to one side of the heat sink, and semiconductor cooling chips are fixedly connected to both sides of the heat sink. Multiple vents are provided on the top of the heat sink.

[0019] By adopting the above technical solution, external air can be drawn into the heat sink while the fan is running.

[0020] Furthermore, a dustproof mesh is fixedly connected to the outer side of the fan, and a second dustproof mesh is fixedly connected to the outer side of the semiconductor cooling chip.

[0021] By adopting the above technical solution, dust in the air can be blocked by dustproof net one and dustproof net two, preventing dust from entering the heat sink or coming into contact with the surface of the semiconductor cooling chip.

[0022] In summary, this application includes at least one of the following beneficial effects; 1. In this application, multiple iron cores are detachably connected inside the annular housing. When it is necessary to replace the iron core, the fixing parts can be manually operated to release the fixing parts from the cover, and then the cover can be pulled out from the annular housing to open the annular housing. After that, the iron core can be manually pulled out from the annular housing to complete the disassembly and replacement of the iron core. This realizes the modular installation of the iron core, and the installation and disassembly steps are convenient, which improves the maintenance efficiency of the transformer, greatly shortens the downtime of the transformer, and improves the practicality of the transformer.

[0023] 2. In this application, when the transformer is in operation, the internal components of the heat sink can draw external air into the heat sink and form cold air inside the heat sink. Then, the cold air is drawn into the annular shell to cool the iron core, thereby reducing the possibility of the iron core temperature rising too quickly and causing damage during operation, increasing the service life of the transformer, reducing the frequency of maintenance, and improving the practicality of the transformer.

[0026] The following is in conjunction with the appendix Figure 1 —6 provides further detailed description of this application.

[0027] This application discloses a toroidal transformer structure.

[0028] Reference Figure 1 and Figure 2 A toroidal transformer structure includes a mounting base plate 1, a heat sink 2 fixedly connected to the top of the mounting base plate 1, an annular shell 3 fixedly connected to the top of the heat sink 2, and the top of the heat sink 2 communicating with the annular shell 3. A cover 4 is installed on the top of the annular shell 3, and multiple detachable iron cores 6 are installed inside the annular shell 3. A fixing member 5 is provided on the cover 4, and the annular shell 3 and the cover 4 are fixedly connected by the fixing member 5. Here, the iron core 6 is made of amorphous alloy strip to form an annular body. The strip is arranged in an orderly manner along the annular direction by magnetic domain orientation control technology, and a stepped lamination structure design is adopted. The seams of each lamination layer are staggered by 15 degrees, and the surface of the iron core 6 is coated with a silicon nitride coating.

[0029] When using this transformer, multiple iron cores 6 can be inserted into the annular housing 3 first. Then, the cover 4 is placed on top of the annular housing 3 to form a seal. Next, the fixing piece 5 is inserted through the cover 4 into the annular housing 3 and forms a rotatable connection with the heat sink 2, thereby fixing the cover 4 onto the annular housing 3. This completes the assembly of the transformer. After assembly, the mounting base plate 1 can be fixed to the installation location using external fixing bolts. The iron cores 6 are modularly installed. When individual iron cores 6 are damaged and need to be replaced, the fixing piece 5 can be manually operated to release the fixing piece 5 from the cover 4. Then, the cover 4 can be pulled out from the annular housing 3 to open the annular housing 3. After that, the iron cores 6 can be manually pulled out from the annular housing 3 to complete the disassembly and replacement of the iron cores 6. This improves the maintenance efficiency of the transformer and significantly shortens the transformer downtime.

[0030] When the transformer is in operation, the operation of the internal components of the heat sink 2 can draw in external air and form cold air, which is then sent into the annular shell 3 to cool the iron core 6. This reduces the possibility of the iron core 6 being damaged due to excessively rapid temperature rise during transformer operation, improves the service life of the transformer, and reduces the frequency of maintenance.

[0031] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 Multiple partition plates 31 are fixedly connected to the inner side of the annular shell 3, forming an installation chamber between two partition plates 31. The iron core 6 is slidably installed inside the installation chamber. Slide grooves 32 are provided on both sides of the partition plates 31. Slider blocks 61 are fixedly connected to both sides of the iron core 6. The sliders 61 are slidably installed inside the slide grooves 32. A through hole 42 is provided in the middle of the cover 4, and multiple positioning rods 41 are fixedly connected to the bottom of the cover 4. Multiple positioning holes 33 are provided at the top of the annular shell 3. The positioning rods 41 are inserted into the positioning holes 33. The fixing component 5 includes a fixing pin 51 that passes through and is connected inside the through hole 42. A baffle 52 is fixedly connected to the top of the fixing pin 51. A threaded hole 26 is provided at the top of the heat sink 2. The bottom end of the fixing pin 51 is threadedly connected to the threaded hole 26.

[0032] When it is necessary to disassemble and replace the iron core 6, the baffle 52 can be manually rotated to make the fixing pin 51 rotate, so that the fixing pin 51 is disengaged from the threaded hole 26. Then, the fixing pin 51 is pulled out from the through hole 42, and the cover 4 is manually lifted so that the positioning rod 41 is pulled out from the positioning hole 33. The cover 4 can then be removed, exposing the iron core 6. At this time, the damaged iron core 6 can be pulled out, and the slider 61 can be pulled out from the slide groove 32, thus realizing the removal and replacement of the iron core 6 from the installation chamber.

[0033] Reference Figure 6 Multiple fans 22 are fixedly connected to one side of the heat sink 2, and semiconductor cooling chips 23 are fixedly connected to both sides of the heat sink 2. Multiple vents 21 are opened on the top of the heat sink 2. A dustproof mesh 24 is fixedly connected to the outside of the fan 22, and a dustproof mesh 25 is fixedly connected to the outside of the semiconductor cooling chip 23.

[0034] With the operation of multiple fans 22, external air can be drawn into the heat sink 2. At this time, the operation of the semiconductor cooling chip 23 can reduce the internal temperature of the heat sink 2, so that the air drawn into the heat sink 2 forms cold air, which is sent into the annular shell 3 through the vent 21. This can cool the iron core 6, reduce the possibility of the iron core 6 being damaged due to excessive temperature rise during the operation of the transformer, improve the service life of the transformer, and reduce the frequency of maintenance.

[0035] Here, the cold end of the thermoelectric cooler 23 is located inside the heat sink 2, and the hot end of the thermoelectric cooler 23 is located outside the heat sink 2. The dust filter 24 can filter dust in the air and prevent dust from entering the annular housing 3 and affecting the operation of the transformer. Both the dust filter 24 and the dust filter 25 are made of stainless steel wire, which can protect the thermoelectric cooler 23 and the dust filter 25 while blocking dust.

[0036] Working principle: When using this transformer, multiple iron cores 6 can be inserted into the annular housing 3 first. Then, the cover 4 is placed on top of the annular housing 3 to form a seal. Next, the fixing piece 5 is inserted through the cover 4 into the annular housing 3 and forms a rotatable connection with the heat sink 2, thereby fixing the cover 4 onto the annular housing 3. This completes the assembly of the transformer. After assembly, the mounting base plate 1 can be fixed to the installation location using external fixing bolts. The iron cores 6 are modularly installed. When individual iron cores 6 are damaged and need to be replaced, the fixing piece 5 can be manually operated to release the fixing piece 5 from the cover 4. Then, the cover 4 can be pulled out from the annular housing 3 to open the annular housing 3. After that, the iron cores 6 can be manually pulled out from the annular housing 3 to complete the disassembly and replacement of the iron cores 6. This improves the maintenance efficiency of the transformer and significantly shortens the transformer downtime.

[0037] When the transformer is in operation, the operation of multiple fans 22 can draw outside air into the heat sink 2. At this time, the operation of the semiconductor cooling chip 23 can reduce the internal temperature of the heat sink 2, so that the air drawn into the heat sink 2 forms cold air, which is sent into the annular shell 3 through the vent 21. This can cool the iron core 6, reduce the possibility of the iron core 6 being damaged due to excessively rapid temperature rise during transformer operation, improve the service life of the transformer, and reduce the frequency of maintenance.
