Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to a split frame and a two-phase reactor thereof. Background Art

[0002] The skeleton and core design of traditional reactors tend to be integrated. When they need to be used in pairs, they not only take up a large space, but also have unsatisfactory electrical performance. In order to cope with these problems, the industry has launched active explorations. For example, the Chinese patent CN212990885U introduces an EE-type dual-mode filter, whose skeleton adopts an integrated dual hollow channel design, and two magnetic cores pass through the skeleton to form a "sun"-shaped structure. However, this technical solution still has the following shortcomings: the primary problem is that the use of an integrated skeleton limits its flexibility and scalability. Specifically, it becomes particularly difficult to install windings in narrow hollow channels, which seriously affects assembly efficiency. In addition, the reduction in winding size leads to a narrow lead-out space, and the two lead-out wires on the same side are too close, which undoubtedly increases the difficulty of electrical connection and insulation treatment. At the same time, the skeleton components lack effective identification and differentiation methods, making it difficult to quickly and accurately identify different skeleton components during the assembly process, further slowing down the assembly speed. Finally, the winding configuration is relatively fixed, and it is difficult to meet the diverse requirements of different circuits for inductance values ​​and electrical characteristics. For example, there may be limitations in achieving inductance doubling or enhancing series characteristics. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a split frame and a two-phase reactor thereof.

[0004] The technical solution adopted by the present invention is as follows: A split frame includes a split frame component, the frame component includes an anti-foolproofing part, the anti-foolproofing part is located on both sides of the frame component, and anti-foolproofing protrusions and anti-foolproofing grooves are respectively arranged on both sides of the edge; adjacent frame components are concave-convexly embedded into one through the anti-foolproofing protrusions and anti-foolproofing grooves.

[0005] This technical solution adopts a split structure to replace the integrated skeleton, and uses a variety of anti-fool parts to achieve the concave-convex fit of adjacent skeleton components, thereby forming a stable connection. The advantage of the split skeleton is that it allows multiple windings to be installed in the same magnetic core, which is not only more compact but also less expensive than two independent reactors. The form of the anti-fool part is flexible and varied, and the anti-fool protrusion and the anti-fool groove are only two of the implementation methods. By combining its own anti-fool protrusion with the anti-fool groove of the adjacent component, or vice versa, a complete skeleton structure can be constructed. In order to further enhance the firmness of the concave-convex fit, the anti-fool protrusion and the anti-fool groove are set at multiple positions at the same time. For example, anti-fool protrusions are provided at the four end corners of the splicing surface of the skeleton component, that is, a total of four anti-fool protrusions are set, and the adjacent skeleton components are correspondingly provided with four anti-fool grooves. Through this multi-point concave-convex fit setting, a better fixing effect is ensured.

[0006] In addition, the split frame proposed in the present invention also has the following additional technical features: According to an embodiment of the present invention, the cross-section of the fool-proof protrusion is T-shaped, dovetail-shaped, elliptical, hypotenuse-shaped, and diamond-shaped.

[0007] In the technical solution, the foolproof protrusion is a part protruding outward from the main body of the frame component, and its cross-section has various forms. The bottom edge is provided with a locking bevel and a locking arc edge that match the foolproof groove, which is used to achieve the concave-convex fit between adjacent frame components. On the same splicing surface, the cross-sectional shape of the foolproof protrusion is both the same and different; for example, the two foolproof protrusions above the splicing surface may be T-shaped, while the two below may be beveled.

[0008] According to an embodiment of the present invention, the fool-proof groove is a vertical channel arranged from top to bottom, and a hook portion cooperating with the fool-proof protrusion is arranged at the lower part of the vertical channel.

[0009] In the present technical solution, the cross-sections of the fool-proof groove and the fool-proof protrusion are not completely consistent. The purpose of setting the fool-proof groove is to enable the fool-proof protrusion to fit smoothly from top to bottom, so the upper part thereof needs to be completely open to form a vertical fitting channel. Therefore, only the bottom of the fool-proof groove matches the shape of the fool-proof protrusion, that is, the hook of the fool-proof groove can fit with the locking bevel and locking arc edge of the fool-proof protrusion. According to actual needs, the splicing direction is flexible and diverse, not only from top to bottom, but also from bottom to top, from front to back and other different directions. Even a mixed splicing method is used, such as assembling one part from top to bottom first, and then assembling the other part from front to back. As long as two adjacent skeleton components are combined together by means of concave and convex fitting, they all fall within the protection scope of the present invention.

[0010] According to an embodiment of the present invention, the fool-proof portion is also provided with a mark for distinguishing different skeleton components, and the mark is a protrusion, text, number or color texture.

[0011] In this technical solution, since the skeleton components can be wound with windings in different directions, they need to be distinguished. There are various ways to distinguish them, including identification by the cross-sectional shape of the anti-fool protrusions and identification by markings. For example, some skeleton components have no markings on the surface, while others have features such as protrusions, text, numbers or color textures at specific locations. Using these features, different skeleton components can be easily spliced ​​together, thereby improving assembly efficiency.

[0012] According to one embodiment of the present invention, the skeleton assembly is arranged in an H-shape, and further comprises a winding portion and a fixing portion, wherein the winding portion, the foolproof portion and the fixing portion are integrally formed, wherein: The winding part is located in the middle of the frame assembly, on which the winding is wound; the fixing part is located in the lower part of the frame assembly, on which pins matching with the winding lead wire are arranged.

[0013] In this technical solution, the skeleton component can be arranged in an H-shape, with the joint surfaces being perpendicular to each other. At the same time, other special-shaped structures can also be selected. As long as sufficient winding space is left in the middle of the skeleton component and it can form a whole after the concave and convex parts are fitted together, the requirements can be met.

[0014] According to one embodiment of the present invention, the fixing portion includes a pin and an inclined guide column located in the middle of the pin, and the inclined guide column is used to space two lead wires of the winding.

[0015] In this technical solution, due to the small size of the skeleton assembly, the size of the winding is also reduced accordingly, which makes the originally spacious winding lead-out space narrow, causing the two lead-out wires on the same side to be too close. To solve this problem, two measures are taken: on the one hand, a spacer is added between the two lead-out wires, usually a piece of insulating paper, to increase the distance between them; on the other hand, in order to facilitate the fixation of the lead-out wire and avoid the lead-out wire bending angle from getting out of control, a tilted guide column is specially set up, which not only plays a spacing role, but also can effectively control the bending shape of the lead-out wire.

[0016] To achieve the above object, the present invention also provides a two-phase reactor.

[0017] A two-phase reactor comprises a skeleton assembly, a butt-jointed magnetic core silicon steel and a winding, wherein: The frame assembly is integrated with the adjacent frame assembly through the foolproof part; Butt-jointed magnetic core silicon steel, including EE / EI type silicon steel that is separately arranged, adjacent EE / EI type silicon steels are butt-jointed left and right after passing through the skeleton assembly to form the magnetic core silicon steel of the reactor; Windings are separately and independently wound on the winding parts of two skeleton components, and the lead wires of the windings extend to the fixing parts of the skeleton components respectively.

[0018] While optimizing the structure of the skeleton components, this technical solution also improves the butt-jointed core silicon steel. The non-traditional EE / EI type silicon steel is used for butt-joint and welding. The cross-section of the EE / EI type silicon steel can better cooperate with multiple skeleton components, and the cross-section of the butt-jointed core silicon steel after splicing presents a "mu" character structure. In addition, compared with two independent skeletons, the volume of the windings is greatly reduced, and the winding can be pre-wound on the split skeleton components and then assembled; compared with the structure with two installation spaces in the integral structure, the split prefabrication method not only improves the winding efficiency but also makes the operation more convenient.

[0019] According to an embodiment of the present invention, the EE / EI type silicon steel is formed by butt-jointing two parts, including the E-type silicon steel on one side and the E-type silicon steel or I-type silicon steel on the other side.

[0020] In this technical solution, in view of the unconventional structure formed after the splicing of the skeleton components, the butt-jointed core silicon steel is particularly improved. The butt-jointed core silicon steel adopts a symmetric double-E type structure and also an asymmetric structure, such as the E-type silicon steel on one side and the I-type silicon steel on the other side.

[0021] According to an embodiment of the present invention, the windings are divided into the following two configurations according to requirements: Two windings wound in the same direction, equivalent to two products connected in series, with reduced volume and doubled characteristics; Two windings wound in different directions, equivalent to two products connected in series, with reduced volume and equivalent characteristics.

[0022] In this technical solution, in view of the split structure of the skeleton components, the winding methods on different skeleton components are different, thus bringing diverse electrical effects. For the winding configuration wound in the same direction, when current flows through one of the windings, a magnetic field will be generated around it. Since the two windings are wound in the same direction, the magnetic field directions they are in are the same, so a positive mutual inductance effect will be generated, making the electromotive forces in the two windings superimpose on each other, and then doubling the inductance value; this configuration is particularly suitable for circuits that require a high inductance value to improve the stability and filtering performance of the circuit. On the contrary, for the winding configuration wound in the opposite direction, the magnetic fields generated by the two windings will partially cancel each other out, but their electromotive forces in the circuit are still in series; this configuration helps to reduce the electromagnetic interference generated when the current changes, thereby improving the anti-interference ability of the circuit.

[0023] According to an embodiment of the present invention, an insulating material for enhancing the isolation effect is provided between the two lead wires on the same side of the winding.

[0024] In this technical solution, the electrical isolation characteristics of the insulating material are utilized to ensure the electrical isolation between the winding leads and between them and the surrounding circuit components, which helps to reduce electromagnetic interference.

[0025] Compared with the prior art, the present invention has the following beneficial effects: (1) By adopting a split-type skeleton structure and combining with a diversified anti-fooling structure, precise concave-convex fitting of adjacent skeleton components is achieved, simplifying the assembly process and improving the assembly efficiency; (2) The markings on the anti-fooling part enhance the distinguishability of different skeleton components and avoid assembly errors; (3) The magnetic core silicon steel is butt-jointed and welded using non-traditional EE / EI type silicon steel, and its cross-section can be well matched with multiple skeleton components to form a "mu" character structure, enhancing the overall electrical performance of the reactor; (4) The windings are divided into two configurations of co-directional winding and reverse winding according to requirements, which are respectively used to achieve inductance value doubling and enhance the series characteristics, meeting the requirements of different circuits for inductance value and anti-interference ability; (5) The insulating material between the winding leads effectively reduces electromagnetic interference, and the inclined guide posts between the winding leads not only play a spacing role but also can effectively control the bending form of the leads.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1 like Figures 1 to 3 As shown, this embodiment provides a split skeleton, including a separately arranged skeleton component 1, the skeleton component 1 includes an anti-foolproofing portion 12, the anti-foolproofing portion 12 is located on both sides of the skeleton component 1, and anti-foolproofing protrusions 121 and anti-foolproofing grooves 122 are respectively provided on both sides of the edge thereof; adjacent skeleton components 1 are concavely and convexly engaged into one through the anti-foolproofing protrusions 121 and the anti-foolproofing grooves 122.

[0036] This technical solution adopts a split structure to replace the integrated skeleton, and uses a variety of anti-fool parts 12 to achieve the concave-convex fit of adjacent skeleton components 1, thereby forming a stable connection. The advantage of the split skeleton is that it allows multiple windings 3 to be installed in the same magnetic core, which is not only more compact but also less expensive than two independent reactors. The form of the anti-fool part 12 is flexible and varied, and the anti-fool protrusion 121 and the anti-fool groove 122 are only two of the implementation methods. By combining its own anti-fool protrusion 121 with the anti-fool groove 122 of the adjacent component, or vice versa, a complete skeleton structure can be constructed. In order to further enhance the firmness of the concave-convex fit, the anti-fool protrusion 121 and the anti-fool groove 122 are set at multiple positions at the same time. For example, anti-fool protrusions 121 are provided at the four end corners of the splicing surface of the skeleton component 1, that is, a total of four anti-fool protrusions 121 are provided, and the adjacent skeleton component 1 is correspondingly provided with four anti-fool grooves 122. This multi-point concave-convex fitting setting ensures a better fixing effect.

[0037] like Figures 1 to 3 As shown, the skeleton assembly 1 is arranged in an H shape, and further comprises a winding portion 11 and a fixing portion 13. The winding portion 11, the foolproof portion 12 and the fixing portion 13 are integrally formed, wherein: The winding part 11 is located in the middle of the skeleton component 1 , on which the winding 3 is wound; the fixing part 13 is located in the lower part of the skeleton component 1 , on which pins matching with the lead wires of the winding 3 are arranged.

[0038] In this technical solution, the skeleton component 1 can be arranged in an H-shape, with its joint surfaces perpendicular to each other. At the same time, other special-shaped structures can also be selected. As long as enough winding space for the winding 3 is left in the middle of the skeleton component 1 and it can form a whole after the concave and convex parts are fitted together, the requirements can be met.

[0039] According to an embodiment of the present invention, the fixing portion 13 includes a pin and an inclined guide column located in the middle of the pin, and the inclined guide column is used to space two lead wires of the winding 3.

[0040] In this technical solution, due to the small size of the skeleton assembly 1, the size of the winding 3 is also reduced accordingly, which makes the originally spacious winding 3 lead-out space narrow, causing the two lead-out wires on the same side to be too close. To solve this problem, two measures are taken: on the one hand, a spacer is added between the two lead-out wires, usually a piece of insulating paper, to increase the distance between them; on the other hand, in order to facilitate the fixation of the lead-out wire and avoid the lead-out wire bending angle from getting out of control, a tilted guide column is specially set up, which not only plays a spacing role, but also can effectively control the bending shape of the lead-out wire.

[0041] Working principle: This split skeleton realizes stable connection through the split skeleton component 1, which is connected by the concave-convex fit of the anti-fool protrusion 121 and the anti-fool groove 122; the skeleton component 1 is H-shaped or other special-shaped structures, as long as there is a winding space for the winding 3 in the middle and it forms a whole after fit; the H-shaped skeleton includes a winding part 11, an anti-fool part 12 and a fixing part 13, the winding part 11 is located in the middle for winding the winding 3, and the fixing part 13 is located in the lower part and is provided with a pin to cooperate with the lead-out wire of the winding 3; in order to solve the problem of narrow lead-out wire space caused by the reduction in the size of the winding 3, an insulating paper spacer is added between the lead-out wires, and an inclined guide column is set to control the bending shape and fixed position of the lead-out wire; the split skeleton has a compact structure and low cost, and ensures a better fixing effect through multi-point concave-convex fit.

[0042] Example 2 Based on Example 1, Figures 1 to 3 As shown, the cross-section of the fool-proof protrusion 121 is T-shaped, dovetail-shaped, elliptical, hypotenuse-shaped, and diamond-shaped.

[0043] In the present technical solution, the foolproof protrusion 121 is a part protruding outward from the main body of the frame component 1, and its cross-section has various forms, and the bottom edge is provided with a locking bevel and a locking arc edge matching the foolproof groove 122, so as to realize the concave-convex fitting between adjacent frame components 1. On the same splicing surface, the cross-sectional shapes of the foolproof protrusions 121 are both the same and different; for example, the two foolproof protrusions 121 above the splicing surface may be T-shaped, while the two below may be beveled.

[0044] According to an embodiment of the present invention, the fool-proof groove 122 is a vertical channel arranged from top to bottom, and a hook portion cooperating with the fool-proof protrusion 121 is arranged at the lower portion of the vertical channel.

[0045] In the present technical solution, the cross-sections of the fool-proof groove 122 and the fool-proof protrusion 121 are not completely consistent. The purpose of setting the fool-proof groove 122 is to enable the fool-proof protrusion 121 to fit smoothly from top to bottom, so its upper part needs to be completely open to form a vertical fitting channel. Therefore, only the bottom of the fool-proof groove 122 matches the shape of the fool-proof protrusion 121, that is, the hook of the fool-proof groove 122 can fit with the locking bevel and locking arc edge of the fool-proof protrusion 121. According to actual needs, the splicing direction is flexible and diverse, not only from top to bottom, but also from bottom to top, from front to back and other different directions. Even a mixed splicing method is used, such as assembling one part from top to bottom first, and then assembling another part from front to back. As long as two adjacent skeleton components 1 are combined together by means of concave and convex fitting, they all fall within the protection scope of the present invention.

[0046] Example 3 Based on Example 1, the fool-proof portion 12 is further provided with a mark for distinguishing different skeleton components 1, and the mark is a protrusion, text, number or color texture.

[0047] In the present technical solution, since the skeleton components 1 can be wound with windings 3 in different directions, they need to be distinguished. There are various ways to distinguish them, including identification by the cross-sectional shape of the fool-proof protrusions 121 and identification. For example, some skeleton components 1 have no identification on the surface, while others have features such as protrusions, text, numbers or color textures at specific locations. Using these features, different skeleton components 1 can be easily spliced ​​together, thereby improving assembly efficiency.

[0048] Example 4 Based on Example 1, Figures 4 to 5 As shown, this embodiment provides a two-phase reactor, including a skeleton component 1, a butt-jointed magnetic core silicon steel 2 and a winding 3, wherein: The frame assembly 1 is integrated with the adjacent frame assembly 1 through the foolproof portion 12; The butted magnetic core silicon steel 2 includes EE / EI type silicon steels which are separately arranged, and adjacent EE / EI type silicon steels are butted together on the left and right after passing through the skeleton component 1 to form the magnetic core silicon steel of the reactor; The windings 3 are independently wound on the winding parts 11 of the two frame components 1 , and the lead wires of the windings 3 extend to the fixing parts 13 of the frame components 1 .

[0049] While optimizing the structure of the skeleton component 1, this technical solution also improves the butt joint core silicon steel 2, and uses non-traditional EE / EI type silicon steel for butt joint and welding. The cross-section of the EE / EI type silicon steel can be better matched with multiple skeleton components 1, and the cross-section of the butt joint core silicon steel 2 after splicing presents a "mu" character structure. In addition, compared with two independent skeletons, the volume of the winding 3 is greatly reduced, and the winding 3 can be pre-wound on the split skeleton components 1 and then assembled; compared with the structure with two installation spaces in the integrated structure, the split prefabrication method not only improves the winding efficiency but also makes the operation more convenient.

[0050] According to an embodiment of the present invention, an insulating material for enhancing the isolation effect is provided between two lead-out wires on the same side of the winding 3.

[0051] In this technical solution, by utilizing the electrical isolation characteristics of the insulating material, the electrical isolation between the lead-out wires of the winding 3 and between them and the surrounding circuit elements is ensured, which helps to reduce electromagnetic interference.

[0052] Working principle: On the winding parts 11 of the two skeleton components 1, the winding 3 is wound independently. The lead-out wires of the winding 3 are cleverly extended to the fixed parts 13 of the skeleton components 1 to facilitate subsequent electrical connection operations; thanks to this split prefabrication method, the winding efficiency of the winding 3 is significantly improved, and the operation steps are also more convenient; to enhance the isolation effect and reduce electromagnetic interference, an insulating material is specially provided between two lead-out wires on the same side of the winding 3; the skeleton components 1 are fitted through the precise anti-fooling parts 12 to build a stable support structure; in addition, the split EE / EI type silicon steel sheets are butted and welded left and right after passing through the skeleton components 1 to jointly form the core silicon steel of the reactor, and its cross-section presents the structural characteristics of a "mu" character. To further improve the overall performance, a fixing glue is filled between the winding 3, the skeleton components 1 and the EE / EI type silicon steel.

[0053] Embodiment 5 Based on Embodiment 1, as Figures 4 to 5 shown, the winding 3 is divided into the following two configurations according to requirements: Two windings wound in the same direction, equivalent to two products connected in series, with reduced volume and doubled characteristics; Two windings wound in different directions, equivalent to two products connected in series, with reduced volume and equivalent characteristics.

[0054] In the present technical solution, in view of the split structure of the skeleton component 1, the winding methods of the windings 3 on different skeleton components 1 are different, thereby bringing about diverse electrical effects. For the configuration of the windings 3 wound in the same direction, when the current flows through one of the windings 3, a magnetic field will be generated around it. Since the two windings 3 are wound in the same direction, the directions of the magnetic fields they are in are consistent, so a positive mutual inductance effect will be generated, so that the electromotive forces in the two windings 3 are superimposed on each other, thereby doubling the inductance value; this configuration is particularly suitable for circuits that require high inductance values ​​to improve the stability and filtering performance of the circuit. On the contrary, for the configuration of the windings 3 wound in the opposite direction, the magnetic fields generated by the two windings 3 will partially cancel each other out, but their electromotive forces in the circuit are still connected in series; this configuration helps to reduce the electromagnetic interference generated when the current changes, thereby improving the anti-interference ability of the circuit.

[0055] Example 6 Based on Example 1, Figure 6 to Figure 7 As shown, the EE / EI type silicon steel is formed by butting together two parts, including E type silicon steel on one side and E type silicon steel or I type silicon steel on the other side.

[0056] In the present technical solution, in view of the unconventional structure formed by the splicing of the skeleton assembly 1, the butt-jointed magnetic core silicon steel 2 is specially improved. The butt-jointed magnetic core silicon steel 2 adopts a symmetrical double E-type structure, and also adopts an asymmetrical structure, such as E-type silicon steel on one side and I-type silicon steel on the other side.
