Description

Technical Field

[0001] This utility model relates to the field of split-type reactor technology, specifically to a split-type reactor for bidirectional converters. Background Technology

[0002] The split reactor of the bidirectional converter is an air-core or iron-core inductor that is installed separately from the converter power module. It is connected in series between the converter and the power grid, ensuring stable bidirectional flow of core electrical energy. It also has its own independent structure, cooling system, and protection and monitoring interfaces.

[0003] The main core components of the split-type reactor in a bidirectional converter include: 1. Filtering: Suppressing high-order harmonics generated during converter operation, reducing electromagnetic interference to the power grid, and reducing the impact of grid voltage distortion on the converter to meet power quality standards; 2. Current limiting: Limiting the rate of change of current, smoothing current fluctuations, preventing voltage spikes from damaging power switching devices, and protecting the converter's safety; 3. Stabilization: Improving system impedance, enhancing the power factor, suppressing system resonance, ensuring the stability of bidirectional power flow, and avoiding abnormal fluctuations.

[0004] In traditional bidirectional converters, the split reactors are typically connected to each other using pins. This connection is not very stable and is easily affected by dust and other vibrations in the environment, which can cause the connection to detach or become covered in dust, affecting the stability of the subsequent connection, leading to loosening of the test tubes, insulation aging, and other problems.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a split-type reactor for a bidirectional converter, comprising a split-type reactor body 1, a connection port 11 fixedly connected to the upper side of the split-type reactor body 1, and a connection wire 12 inserted inside the connection port 11. A protective component 2 is provided on the outside of the connection wire 12, and the protective component 2 includes a fixing ring 21 fixedly connected to the outer side of the end of the connection wire 12 away from the connection port 11. A protective cover 22 is sleeved on the outer side of the fixing ring 21, and an adhesive component 3 is provided on the end of the protective cover 22 near the fixing ring 21. The protective cover 22 is further away from the fixing ring 21. A locking component 4 is provided on the inner side of one end of the ring 21, and a fixing component 5 is provided on the outer side of the end of the cover 22 away from the fixing ring 21. A pressing component 6 is provided on the outer side of the fixing component 5 near the locking component 4, and an installation component 7 is provided on the outer side of the fixing component 5 near the main body 1 of the split reactor. By cooperating with the protective component 2 and the adhesive component 3, the connection port 11 and the connecting wire 12 can be connected, which can effectively improve the stability of the connection, improve the protection effect at the connection point, and reduce the accelerated aging or loosening caused by dust adhesion or external vibration.

[0020] like Figure 4 As shown, the adhesive assembly 3 includes a molded adhesive surface 31 fixedly connected to the inner side of the cover 22 near the fixing ring 21, and a molded adhesive surface 32 is adhered to the inner side of the molded adhesive surface 31, and the inner side of the molded adhesive surface 32 is fixedly connected to the outer side of the fixing ring 21.

[0021] like Figure 4As shown, the locking assembly 4 includes a locking block 41 inserted into the inner side of the end of the cover 22 away from the fixing ring 21, and a spring 42 is fixedly connected to the end of the locking block 41 inserted into the cover 22. The end of the spring 42 away from the locking block 41 is fixedly connected to the cover 22. During the insertion of the locking block 41, the sleeve 51 squeezes the locking blocks 41 at both ends of the cover 22. After the locking block 41 is squeezed, it is inserted into the cover 22 and compresses the spring 42.

[0022] like Figure 4 As shown, the fixing component 5 includes a sleeve 51 sleeved on the outer side of the end of the cover 22 away from the fixing ring 21, and a sealing gasket 52 is fixedly connected to the inner side of the upper end of the sleeve 51. The sleeve 51 and the sealing gasket 52 are used to protect the outside of the connection port 11.

[0023] like Figure 4 As shown, the pressing component 6 includes a push block 61 inserted inside the upper end of the sleeve 51, and a rubber button 62 is fixedly connected to the end of the push block 61 away from the sleeve 51. The end of the rubber button 62 close to the sleeve 51 is fixedly connected to the sleeve 51. Pressing the rubber buttons 62 at both ends causes the rubber buttons 62 to squeeze the push block 61 and push the locking block 41.

[0024] like Figure 3 As shown, the mounting assembly 7 includes a mounting ring 71 fixedly connected to the outer side of the lower end of the sleeve 51, and a fastening bolt 72 is engaged with the inner thread of the outer end of the mounting ring 71. The lower thread of the fastening bolt 72 is engaged in the body 1 of the split reactor. The mounting ring 71 and the sleeve 51 can be removed and replaced by unscrewing the fastening bolt 72.

[0025] like Figure 3 As shown, the protective cover 22 is fan-shaped, and the protective cover 22 is set in a conical shape around the fixing ring 21.

[0026] Working principle: When the connecting wire 12 is installed onto the connecting port 11, the protective cover 22 is first moved to wrap around the outside of the fixing ring 21 with the molded adhesive surface 31. The protective cover 22 is fixed by the adhesion between the molded adhesive surface 31 and the molded adhesive surface 32. Then, the connecting wire 12 moves the protective cover 22 into the sleeve 51. During the insertion process, the sleeve 51 presses the locking blocks 41 at both ends of the protective cover 22. After the locking blocks 41 are pressed, they are inserted into the protective cover 22 to compress the spring 42. Then, when the protective cover 22 is attached to the sealing gasket 52, the spring 42 is used to press the sealing gasket 52 to release the sealing gasket 52. The elastic potential energy of 2 pushes the locking block 41 out, so that the locking block 41 can be inserted into the sleeve 51 to lock the cover 22 and the connecting line 12. When removing the connecting line 12, you can first press the rubber buttons 62 at both ends, so that the rubber buttons 62 squeeze the push block 61 to push the locking block 41. After the locking block 41 is pushed out of the sleeve 51, you can pull the connecting line 12 to pull out the cover 22 and the connecting port 11 and the sleeve 51 for removal. Alternatively, you can unscrew the fastening bolt 72 to remove and replace the mounting ring 71 and the sleeve 51.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
