[0015] From the above description of the present invention and its preferred embodiments, it can be seen that, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0016] The applicant has learned through continuous observation, experimentation and research that the reason for the technical problem of "it is difficult to fix the upper part of the reactor to the cabinet" in the existing technical solution is that, in addition to the reactor, there are other electrical components at the bottom of the cabinet. Therefore, there is often a gap between the air duct of the reactor and the side wall of the cabinet. If the upper part of the reactor is to be fixed to the cabinet, a connecting beam can only be set in the cabinet. The connecting beam passes through the air duct and is fixed to the upper part of the reactor. In order to ensure that the connecting beam can pass through the air duct, the air duct must be made of multiple plates spliced ​​together. Therefore, during installation, the connecting beam must first pass through the air duct and connect the connecting beam to the upper part of the reactor. After the parts are fixed, the air guide cover is spliced, and after the air guide cover is spliced, it must be fixed to the cabinet. The overall assembly steps are cumbersome and difficult to assemble. In addition, the splicing points and the points where the connecting beams pass through are prone to air leakage. The air guide cover of the splicing structure inevitably has tolerances, which will further increase the air leakage, greatly reducing the heat dissipation efficiency of the reactor. If the side wall of the cabinet is directly formed as a part of the air guide cover, although the upper part of the reactor can be fixed to the cabinet, the electrical components in the electrical cabinet need to be rearranged, which is time-consuming and labor-intensive and cannot guarantee the heat dissipation efficiency of the electrical components in the cabinet and the convenience of wiring, etc. This solution is generally not adopted in the prior art.

[0017] In technical solution one and its preferred embodiment, the connecting part is suitable for fitting with the inner surface of the connecting wall, the connecting part is provided with a connecting hole, the connecting beam is suitable for fitting with the outer surface of the connecting wall and is provided with a locking hole, and the fastener is suitable for penetrating the corresponding locking hole, the through hole and the connecting hole to lock the connecting part and the connecting beam. Therefore, the entire air duct cover only needs to open a through hole to lock the connecting part and the connecting beam through the fastener, and also lock the connecting wall and the connecting beam, so that the upper part of the reactor and the upper part of the air duct cover are both locked to the cabinet body. Compared with the solution in which the connecting beam passes through the air duct cover and locks the reactor, there is no need to open a through hole on the air duct cover for the connecting beam to pass through. This through hole is generally larger, and the periphery of the through hole is prone to air leakage, and the air duct cover does not need to form a splicing structure. The splicing of the splicing structure is also prone to air leakage, and the splicing structure still has tolerances and cumbersome assembly steps. More importantly, since the connecting part fits with the inner surface of the connecting wall, the connection The beam fits the outer surface of the connecting wall, and the through hole of the connecting wall is penetrated by the fastener. After the fastener is locked, the through hole and its edge are basically sealed. Therefore, the air guide cover has good airtightness and high protection. It is not only easy to guide the wind, but also waterproof and dustproof. Therefore, compared with the solution of the connecting beam passing through the air guide cover in the prior art, this technical solution has high protection, simple assembly, and high heat dissipation efficiency of the reactor; compared with the solution that the side wall of the cabinet forms a part of the air guide cover, there is no need to change the layout of the electrical parts of the electrical cabinet, which is simple and labor-saving; and this connection method allows the upper part of the reactor and the upper part of the air guide cover to be locked with the cabinet outside the air guide cover, which is convenient for installation. Because the connecting part fits the inner surface of the connecting wall, the connecting beam fits the outer surface of the connecting wall, and the surface fitting method makes the structure stable after the connecting part is connected to the connecting beam, and the structure is stable after the connecting wall is connected to the connecting beam, so that the structure of the reactor assembly is stable. In addition, the setting of the connecting part makes full use of the structure of the reactor, and the structure is simpler.

[0018] In technical solution two and its preferred embodiment, the length direction of the reactor and the air guide cover are both in the X-axis direction, and the width direction is both in the Y-axis direction; the connecting wall is perpendicular to the Y-axis direction and is provided with at least two through holes along the X-axis direction, and the connecting beam is located on one side of the air guide cover along the Y-axis direction and extends along the X-axis direction. Therefore, the connecting beam can be fixedly connected to the connecting beam on one side of the reactor along the Y-axis direction. Compared with being fixedly connected to the connecting beam on one side of the air guide cover along the X-axis direction, the reactor and the air guide cover of this technical solution have more fixing points and a more stable structure; compared with being fixedly connected to the connecting beam on both sides of the reactor along the X-axis direction, the number of connecting beams can be reduced, which is more convenient for the installation of fasteners; in addition, it is more conducive to avoiding other electrical components in the cabinet.

[0019] In technical solution three and its preferred embodiment, the reactor is provided with a coil frame, a magnetic core fixed to the coil frame and extending along the vertical Z-axis direction, and a connector fixed to the coil frame, the connector is provided with a connecting portion, the connecting portion is located above the magnetic core and outside the magnetic core, and the connecting portion is fully utilized to set the structural setting of the coil frame of the reactor, which is conducive to processing and makes it easier for the air guide cover to avoid the coil of the reactor.

[0020] In technical solution four and its preferred embodiment, there are two connectors, which are arranged along the Y-axis direction and extend along the X-axis direction; a connecting portion is provided on the connector close to the connecting wall, and a lifting portion is provided on the connector away from the connecting portion; at least two first lifting holes arranged along the X-axis direction are also provided on the connecting portion, so that the connecting portion can be used for external lifting when the reactor is lifted, and can be fixed to the reactor and the cabinet when the reactor is installed; in actual application, the lifting hole is the structure of the reactor itself, that is, the connecting portion is the structure of the reactor itself, so the improvement of the present application mainly lies in the opening of the connecting hole on the connecting portion, thereby realizing the fixed connection between the reactor and the cabinet with the least improvement; a second lifting hole is provided on the lifting portion, so that multiple lifting points are formed above the reactor, which is more conducive to maintaining balance; in addition, in actual application, the structures of the two connectors are consistent, which is more conducive to processing, and it is beneficial for the connecting portion to have a larger length in the X-axis direction, thereby facilitating the simultaneous formation of the lifting hole and the connecting hole.

[0021] In technical solution five and its preferred embodiments, the connecting member is provided with a connecting plate extending along the X-axis direction and lugs that are equal to and correspond to the number of through holes, the connecting plate is fixedly connected to the coil frame, and each lug is fixedly connected to the connecting plate; wherein each lug close to the connecting wall side forms a connecting portion, and each lug therein is provided with a first lifting hole and a connecting hole; each lug away from the connecting wall side forms a lifting portion, and each lug therein is provided with a second lifting hole. Compared with the solution in which each lug of each connecting member is connected as one, it is more conducive to processing and saves materials and costs.

[0022] In technical solution six and its preferred embodiments, the connecting piece is also provided with bending portions which are equal to and correspond to the number of lugs; the connecting piece is located below each lug; the bending portions connect the connecting piece and the corresponding lug and are inclined from bottom to top in a direction away from the magnetic core, so that the lug can be further away from the magnetic core, thereby facilitating the connection portion formed by each lug to fit with the connecting wall and making the air guide cover easier to process and avoid the coil of the reactor.

[0023] In technical solution seven and its preferred embodiments, the number of connecting parts is at least two, each connecting part is arranged along the X-axis direction and extends along the Y-axis direction; each connecting part is provided with an abutment wall at one end close to the connecting wall, each abutment wall is provided with a connecting hole, and each abutment wall forms a connecting part, and the structure is simple and easy to process.

[0024] In technical solution eight and its preferred embodiment, the bottom of the coil frame is provided with a base plate fixed to the cabinet, and the top of the coil frame is provided with a supporting surface; the reactor is also provided with a locking member extending in the vertical direction; the connecting member is supported on the supporting surface, and its two ends along the Y-axis direction are fixed to the base plate through the locking member, so the connecting member can ensure the clamping of the reactor in the vertical direction and improve the stability of the reactor, and each connecting member is provided with an abutment wall at one end close to the connecting wall, and each abutment wall is provided with a connecting hole, and each abutment wall forms a connecting portion, so the setting of the connecting portion makes full use of the structure of the reactor itself, and the only improvement required is to set an abutment wall at the end of the connecting member, and the structure is simple and easy to process.

[0025] In technical solution nine and its preferred embodiment, air outlets higher than the magnetic core are respectively provided at both ends of the air guide cover along the X-axis direction; a first lead-out terminal and a second lead-out terminal passing through the air guide cover are provided on the side of the reactor away from the connecting wall, thereby, the various parts of the reactor assembly do not interfere with each other and the structure is simpler.

[0045] See also Figure 1-5 , Figure 1-5 An electrical cabinet is shown, comprising a cabinet body 10 , a reactor assembly and a fastener 40 .

[0046] The cabinet body 10 is in the shape of a cuboid, with its length direction being the Y-axis direction, its width direction being the X-axis direction, and its height direction being the Z-axis direction. A connecting beam 11 extending along the X-axis direction is provided on one side along the Y-axis direction of the cabinet body 10. The connecting beam 11 is a C-shaped channel steel, and at least one locking hole 111 is provided on the bottom wall of the channel of the connecting beam 11.

[0047] The reactor assembly includes an air guide cover 20 and a reactor 30 .

[0048] See also Figure 3-4 The air scoop 20 is used to cover the outside of the reactor 30, and its length direction is the X-axis direction, and its width direction is the Y-axis direction. The bottom of the air scoop 20 is provided with a flange fixed to the bottom of the cabinet 10, and the upper part of the air scoop 20 is provided with a connecting wall 21, which is perpendicular to the Y-axis direction and arranged along the X-axis direction with at least two through holes 211 opened along the Y-axis direction. In this embodiment, the connecting beam 11 is located on one side of the air scoop 20 along the Y-axis direction and the opening of the connecting beam 11 is away from the air scoop 20. The outer surface of the connecting wall 21 is suitable for fitting with the outer surface of the groove bottom wall of the connecting beam 11, and the number of through holes 211 and the locking holes 111 are equal and one-to-one corresponding. The bottom of the air scoop 20 forms an air inlet 22, and the top of the air scoop 20 is provided with air outlets 23 at both ends along the X-axis direction.

[0049] The length direction of the reactor 30 is the X-axis direction, and the width direction is the Y-axis direction. The reactor 30 is provided with a coil frame 31, a magnetic core 32 fixed to the coil frame 31 and extending along the vertical Z-axis direction, and a connecting member 33 fixed to the coil frame 31; the bottom of the coil frame 31 is provided with a bottom plate 311 fixed to the cabinet 10 so that the bottom of the reactor 30 is fixed to the cabinet 10, see Figure 5 , a support surface 312 is provided on the top of the coil frame 31; in this embodiment, the number of the magnetic cores 32 is 3, and the 3 magnetic cores 32 are arranged along the X-axis direction. A coil is wound around each magnetic core 32, and the magnetic core 32 is lower than the air outlet 23.

[0050] Still see Figure 3-5 , there are two connectors 33, which are arranged along the Y-axis direction and extend along the X-axis direction. Both connectors 33 are fixed to the top of the coil frame 31. In this embodiment, the two connectors 33 are mirror-symmetrical about a plane perpendicular to the Y-axis direction. Among them, the connector 33 close to the connecting wall 21 is provided with a connecting portion, and the connector 33 away from the connecting wall 21 is provided with a hanging portion. In this embodiment, the connecting portion and the hanging portion are both sheet structures perpendicular to the Y-axis direction. The connecting portion is suitable for being attached to the inner surface of the connecting wall 21 and is provided with connecting holes 01 that are equal in number and correspond to the through holes 211. The connecting portion is located above the magnetic core 32 and outside the magnetic core 32. Similarly, the hanging portion is also located above the magnetic core 32 and outside the magnetic core 32. The side of the reactor 30 away from the connecting wall 21 is provided with a first lead-out terminal 34 and a second lead-out terminal 35 that penetrate the air guide cover 20 and extend out of the air guide cover 20.

[0051] In this embodiment, see Figure 5The connecting member 33 is provided with a connecting piece 331 extending along the X-axis direction, lugs 332 of the same number and corresponding to the through holes 211, and bending portions 333 of the same number and corresponding to the lugs 332. The connecting piece 331 is fixedly connected to the coil frame 31 and is located below the lugs 332. The bending portions 333 connect the connecting piece 331 and the corresponding lugs 332 and are inclined from bottom to top in a direction away from the magnetic core 32; wherein the lugs 332 on one side close to the connecting wall 21 form a connecting portion, and each of the lugs 332 is provided with a first hanging hole 3321 and a connecting hole 01; wherein the lugs 332 on the side away from the connecting wall 21 form a hanging portion, and each of the lugs 332 is provided with a second hanging hole 3322. Therefore, the connecting portion is provided with at least two first hanging holes 3321 arranged along the X-axis direction and connecting holes 01 of the same number and one-to-one corresponding to the through holes 211; the hanging portion is provided with at least two second hanging holes 3322 arranged along the X-axis direction. In this embodiment, the number of the locking holes 111 and the through holes 211 are both two, and each connecting member 33 is provided with two lugs 332, so the number of the first hanging holes 3321 is two, the number of the second hanging holes 3322 is two, and the number of the connecting holes 01 is two.

[0052] The reactor 30 is also provided with two clamping members 36 arranged along the X-axis direction and extending along the Y-axis direction. The reactor 30 is also provided with a locking member 37 extending along the vertical direction. The clamping member 36 is supported on the supporting surface 312, and its two ends along the Y-axis direction are fixedly connected to the base plate 311 through the locking member 37, thereby improving the stability of the reactor 30 in the Z-axis direction.

[0053] The number of the fasteners 40 is equal to and corresponds to the number of the through holes 211 , and each fastener 40 is suitable for penetrating the corresponding locking hole 111 , the through hole 211 and the connecting hole 01 to lock the connecting portion and the connecting beam 11 .

[0054] During installation, place the reactor assembly in the cabinet 10 and make the outer surface of the connecting wall 21 of the air duct 20 fit with the connecting beam 11. First, fix the bottom plate 311 of the reactor 30 to the cabinet 10, and fix the flange of the air duct 20 to the cabinet 10. Then, pass the fastener 40 through the corresponding locking hole 111, through hole 211 and connecting hole 01 to lock the connecting part to the connecting beam 11.

[0055] In this embodiment, the connecting portion is suitable for fitting with the inner surface of the connecting wall 21, the connecting portion is provided with a connecting hole 01, the connecting beam 11 is suitable for fitting with the outer surface of the connecting wall 21 and is provided with a locking hole 111, and the fastener 40 is suitable for penetrating the corresponding locking hole 111, the through hole 211 and the connecting hole 01 to lock the connecting portion with the connecting beam 11. Therefore, the entire air guide cover 20 only needs to open the through hole 211 to lock the connecting portion with the connecting beam 11 through the fastener 40, and also make the connecting wall 21 and the connecting beam 11 locked, so that The upper part of the reactor 30 and the upper part of the air duct 20 are locked with the cabinet 10. Compared with the solution in which the connecting beam 11 penetrates the air duct 20 and is locked with the reactor 30, it is not necessary to provide a through hole for the connecting beam 11 to penetrate on the air duct 20. This through hole is generally large, and the periphery of the through hole is prone to air leakage. In addition, the air duct 20 does not need to form a splicing structure. The splicing part of the splicing structure is also prone to air leakage. The splicing structure also has tolerances and cumbersome assembly steps. More importantly, since the connecting portion fits the inner surface of the connecting wall 21, The connecting beam 11 is fitted with the outer surface of the connecting wall 21, and the through hole 211 of the connecting wall 21 is fastened into 40 and penetrated. After the fastener 40 is locked, the through hole 211 and its periphery are basically sealed. Therefore, the air guide cover 20 has good airtightness and high protection. It is not only easy to guide the wind, but also waterproof and dustproof. Therefore, compared with the solution of the connecting beam penetrating the air guide cover in the prior art, this embodiment has high protection, simple assembly, and high heat dissipation efficiency of the reactor 30; compared with the solution of the side wall of the cabinet 10 forming a part of the air guide cover 20 In terms of installation, there is no need to change the layout of the electrical components of the electrical cabinet, which is simple and labor-saving; and this connection method allows the upper part of the reactor 30 and the upper part of the wind scoop 20 to be locked with the cabinet 10 outside the wind scoop 20, which is convenient for installation. In addition, since the connecting part fits with the inner surface of the connecting wall 21, and the connecting beam 11 fits with the outer surface of the connecting wall 21, the surface fitting method makes the structure stable after the connecting part is connected to the connecting beam 11, and the structure stable after the connecting wall 21 is connected to the connecting beam 11, thereby making the structure of the reactor assembly stable. In addition, the setting of the connecting part makes full use of the structure of the reactor 30, and the structure is simpler.

[0056] In the present embodiment, the length direction of the reactor 30 and the air guide cover 20 are both in the X-axis direction, and the width direction is both in the Y-axis direction; the connecting wall 21 is perpendicular to the Y-axis direction and is provided with at least two through holes 211 along the X-axis direction; the connecting beam 11 is located on one side of the air guide cover 20 along the Y-axis direction and extends along the X-axis direction; therefore, the reactor 30 can be fixedly connected to the connecting beam 11 on one side of the air guide cover 20 along the X-axis direction; compared with being fixedly connected to the connecting beam 11 on one side of the air guide cover 20 along the X-axis direction, the reactor 30 and the air guide cover 20 of the present technical solution have more fixing points and a more stable structure; compared with being fixedly connected to the connecting beam 11 on both sides of the reactor 30 along the X-axis direction, the number of connecting beams 11 can be reduced, making it easier to install the fastener 40; in addition, it is more conducive to avoiding other electrical components in the cabinet 10.

[0057] In this embodiment, the reactor 30 is provided with a coil frame 31, a magnetic core 32 fixedly connected to the coil frame 31 and extending along the vertical Z-axis direction, and a connector 33 fixed to the coil frame 31. The connector 33 is provided with a connecting portion, which is located above the magnetic core 32 and outside the magnetic core 32. The structural setting of the connecting portion of the coil frame 31 of the reactor 30 is fully utilized, which is convenient for processing and makes it easier for the air guide cover 20 to avoid the coil of the reactor 30.

[0058] In this embodiment, there are two connectors 33, which are arranged along the Y-axis direction and extend along the X-axis direction; a connecting portion is provided on the connector 33 on the side close to the connecting wall 21, and a hoisting portion is provided on the connector 33 on the side away from the connecting portion; the connecting portion is also provided with at least two first hoisting holes 3321 arranged along the X-axis direction, so that the connecting portion can be used for external hoisting when the reactor 30 is hoisted, and can be fixedly connected between the reactor 30 and the cabinet 10 when the reactor 30 is installed; in actual applications, the hoisting holes are the first hoisting holes of the reactor 30 itself. The structure of the reactor 30 itself, that is, the connecting part is the structure of the reactor 30 itself. Therefore, the improvement of the present application mainly lies in that a connecting hole 01 is provided on the connecting part, thereby realizing the fixed connection between the reactor 30 and the cabinet 10 with minimal improvement; a second hanging hole 3322 is provided on the hanging part, so that a plurality of hanging points are formed above the reactor 30, which is more conducive to maintaining balance; in addition, in actual applications, the structures of the two connecting parts 33 are consistent, which is more conducive to processing, and is conducive to the connecting part having a larger length in the X-axis direction, thereby facilitating the simultaneous formation of the hanging hole and the connecting hole 01.

[0059] In this embodiment, the connecting member 33 is provided with a connecting piece 331 extending along the X-axis direction and lugs 332 of the same number and corresponding to the through holes 211. The connecting piece 331 is fixedly connected to the coil frame 31, and each lug 332 is fixedly connected to the connecting piece 331; wherein each lug 332 close to the connecting wall 21 side forms a connecting portion, and each lug 332 therein is provided with a first lifting hole 3321 and a connecting hole 01; each lug 332 away from the connecting wall 21 side forms a lifting portion, and each lug 332 therein is provided with a second lifting hole 3322. Compared with the solution in which each lug 332 of each connecting member 33 is connected as one, it is more conducive to processing and saves materials and costs.

[0060] In this embodiment, the connecting piece 33 is also provided with bending portions 333 which are equal in number to and correspond to the lugs 332. The connecting piece 331 is located below each lug 332. The bending portions 333 connect the connecting piece 331 and the corresponding lug 332 and are inclined from bottom to top in a direction away from the magnetic core 32, so that the lug 332 can be further away from the magnetic core 32, thereby facilitating the connection portion formed by each lug 332 to fit with the connecting wall 21 and making the air guide cover 20 easier to process and avoid the coil of the reactor 30.

[0061] In this embodiment, air outlets 23 higher than the magnetic core 32 are respectively provided at both ends of the air guide cover 20 along the X-axis direction; a first lead-out terminal 34 and a second lead-out terminal 35 passing through the air guide cover 20 are provided on the side of the reactor 30 away from the connecting wall 21, thereby, the various parts of the reactor assembly do not interfere with each other and the structure is simpler.

[0062] Example 2

[0063] The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 6 , the connecting member in Example 1 is a hanging member 38 in this embodiment, and its function is to set the hanging hole 02. In this embodiment, the connecting member 33 does not extend along the X-axis direction, and the number of the connecting members 33 is at least two, and each connecting member 33 is arranged along the X-axis direction and extends along the Y-axis direction; each connecting member 33 is provided with an abutting wall 334 perpendicular to the Y-axis direction at one end close to the connecting wall 21, and each abutting wall 334 is provided with a connecting hole 01, and each abutting wall 334 forms a connecting portion; the connecting member 33 is supported on the supporting surface 312, and its two ends along the Y-axis direction are fixedly connected to the bottom plate 311 through the locking member 37. That is to say, the connecting member 33 in this embodiment is formed by the pressing member 36, but the end of the pressing member 36 close to the connecting wall 21 is closed and forms the abutting wall 334.

[0064] In this embodiment, each connector 33 is provided with an abutting wall 334 at one end close to the connecting wall 21, each abutting wall 334 is provided with a connecting hole 01, and each abutting wall 334 forms a connecting portion, which has a simple structure and is easy to process. The connector 33 can ensure the clamping of the reactor 30 in the vertical direction and improve the stability of the reactor 30. Each connector 33 is provided with an abutting wall 334 at one end close to the connecting wall 21, each abutting wall 334 is provided with a connecting hole 01, and each abutting wall 334 forms a connecting portion, so the setting of the connecting portion fully utilizes the structure of the reactor 30 itself, and the only improvement required is to set the abutting wall 334 at the end of the connector 33, which has a simple structure and is easy to process.

[0065] Example 3

[0066] The structure of this embodiment is basically the same as that of the embodiment 1, except that there are two connecting walls 21, which are respectively located on both sides of the air guide cover 20 along the X-axis direction, and are both perpendicular to the X-axis direction and arranged along the Y-axis direction with at least two through holes 211 opened along the X-axis direction; there are two connecting beams 11, which are respectively located on both sides of the air guide cover 20 along the X-axis direction and extend along the Y-axis direction. At this time, the connecting member 33 is basically the same as that of the embodiment 1, except that, see Figure 7-8 The lug 332 of the connector 33 is only provided with a lifting hole 02, but not with a connection hole 01. The two ends of each connector 33 along the X-axis direction form a pressing wall 335 perpendicular to the X-axis direction. The connection hole 01 is formed on each pressing wall 335. The pressing walls 335 on the same side of each connector 33 along the X-axis direction form a connecting portion. In this embodiment, both sides of the upper part of the reactor assembly along the X-axis direction are fixed, which is more conducive to achieving the balance and stability of the reactor assembly.
