[0036] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] Figure 1 The structure of the capacitor cabinet 1 according to an embodiment of the utility model is shown below. Figure 1 The capacitor cabinet 1 will be described.

[0038] like Figure 1 As shown, the capacitor cabinet 1 includes a shell 10, a mounting frame 20 and a plurality of module units 30. The shell 10 has at least one openable surface 11, and the shell 10 is, for example, a protective shell of the capacitor cabinet 1, which reduces damage to the components inside the capacitor cabinet 1 caused by environmental factors, and can also prevent damage caused by accidental touch by other personnel. The shape and size of the shell 10 can be designed according to the installation position and use requirements of the capacitor cabinet 1, preferably in the shape of a rectangular parallelepiped. The openable surface 11 in the shell 10 can be set to push, pull, disassemble, rotate, fold and other forms, as the cabinet door of the shell 10. The shell 10 may include one openable surface 11, or may include multiple openable surfaces 11. For example, the capacitor cabinet 1 is configured to be able to be opened from multiple directions to facilitate the operation of the staff or improve the heat dissipation efficiency.

[0039] The mounting frame 20 is disposed inside the housing 10 . Specifically, the mounting frame 20 may be a skeleton structure with a certain structural strength, including a plurality of parts such as a cross beam, a longitudinal beam, and a column, which can withstand a certain positive pressure and can be used to support the module unit 30 .

[0040] The module unit 30 is installed on the mounting frame 20 , and the module unit 30 includes a connecting frame 31 and an electrical component 32 . The connecting frame 31 is detachably or slidably connected to the mounting frame 20 , and the electrical component 32 is disposed on the connecting frame 31 .

[0041] In this embodiment, the multiple module units 30 in the capacitor cabinet 1 are independent of each other and are arranged in a one-dimensional array or a two-dimensional array on the mounting frame 20. Figure 1 As shown in , the capacitor cabinet 1 includes 4 module units 30, and is arranged in a one-dimensional array in the vertical direction. In other embodiments of the utility model, the plurality of module units 30 may also be arranged in a two-dimensional array, for example, if the capacitor cabinet 1 has a larger width in the horizontal direction, the 4 module units 30 may also be arranged in a 2*2 form.

[0042] In order to improve the space utilization rate inside the capacitor cabinet, the height spacing of the electrical components needs to be reduced as much as possible. However, reducing the height space is not conducive to the maintenance and replacement of the electrical components installed inside, and the available working surface is too small, and the staff does not have the working conditions. Therefore, for conventional capacitor cabinets, there is a contradiction between improving space utilization and facilitating maintenance for staff.

[0043] In the embodiment of the utility model, multiple module units 30 do not affect each other, and the electrical components 32 therein are based on the module unit 30. When the electrical component 32 needs to be repaired or replaced, the module unit 30 corresponding to the electrical component 32 can be disassembled or pulled out from the mounting frame 20, and the staff can repair or replace the electrical component 32 therein from above the module unit 30, without being restricted by the small height space, and there is no need to remove the electrical components blocking the path, which greatly facilitates the operation of the staff and improves the work efficiency. In addition, the module unit 30 in this embodiment can be regarded as a unit, and a module unit 30 can be directly replaced when a fault occurs, and the replaced module unit 30 can be returned to the factory for repair.

[0044] On the other hand, during the production and assembly process of the capacitor cabinet 1, the module unit 30 can be used as an independent production line and stored separately. When assembling a conventional capacitor cabinet, the staff needs to install the multiple electrical components in the capacitor cabinet according to the designed position, but the installation positions that the capacitor cabinet can provide are limited, and usually only one staff member can operate it, which is inefficient. In the embodiment of the utility model, the module unit 30 can be produced on the production line without considering the problem of shielding, which can improve the production efficiency of the capacitor cabinet 1 and reduce the difficulty of processing. In the preferred embodiment of the utility model, the assembly process of the module unit 30 and the mounting frame 20 is simple, which is specifically described in the subsequent embodiments.

[0045] In a preferred embodiment of the utility model, the module unit 30 and the mounting frame 20 are slidably connected, the mounting frame 20 includes a guide rail 21, and the guide rail 21 is inclined relative to the position when the openable surface 11 in the shell 10 is closed. The guide rail 21 is used to guide and limit the sliding direction of the module unit 30 relative to the mounting frame 20. Figure 2 and Figure 3 The structure of the module unit 30 and the guide rail 21 according to the preferred embodiment of the utility model is shown below. Figure 2 and Figure 3 The specific structure and connection relationship between the module unit 30 and the guide rail 21 will be described.

[0046] like Figure 2 and Figure 3 As shown, the connecting frame 31 includes a sliding portion 311, and the sliding portion 311 is configured to cooperate with the guide rail 21 to drive the connecting frame 31 to slide along the guide rail 21. For example, the guide rail 21 is configured to be in a groove shape, and the sliding portion 311 is configured to be a slider or a roller, and the slider or roller can slide along the groove shape.

[0047] In this embodiment, the module unit 30 is configured to be able to slide relative to the guide rail 21. Preferably, the extension direction of the guide rail 21 is configured to be non-parallel to the plane of the closed position of the openable surface 11 in the housing 10. When the openable surface 11 is opened, the module unit 30 can slide in the direction close to the opening of the housing 10 along the direction of the guide rail 21, for example Figure 1 As shown in FIG, the guide rail 21 and the openable surface 11 (in the closed state) are perpendicular to each other, and the module unit 30 can be pulled out along the guide rail 21 .

[0048] Furthermore, according to a preferred embodiment of the utility model, the mounting frame 20 includes a plurality of mutually parallel guide rails 21, and the plurality of guide rails 21 correspond to a plurality of module units 30. Preferably, one module unit 30 corresponds to more than two guide rails 21, so as to disperse the gravity of the module unit 30 and improve the structural stability of the capacitor cabinet 1.

[0049] like Figure 2 As shown, the connecting frame 31 also includes a bearing portion 312, and the electrical component 32 is arranged on the bearing portion 312. Specifically, the connecting frame 31 includes two sliding portions 311, and the two sliding portions 311 are respectively arranged on both sides of the connecting frame 31 and cooperate with the guide rail 21. The bearing portion 312 is arranged between the two sliding portions 311, for example, the bearing portion 312 is a flat plate structure, and the electrical component 32 can be installed on the bearing portion 312.

[0050] In a preferred embodiment of the utility model, when the sliding part 311 slides relative to the guide rail 21, at least part of the module unit 30 is suspended relative to the mounting frame 20 in the extension direction of the guide rail 21, and the module unit 30 can be pulled out from the mounting frame 20. The suspended upper and lower spaces can provide space for the staff to repair and replace the electrical components 32 therein. Further, in order to improve the structural stability of the capacitor cabinet 1, the distance that the module unit 30 is pulled out relative to the guide rail 21 can be limited, for example, not exceeding 1 / 2 of the total length of the module unit 30 along the guide rail 21, or according to the distribution of the center of gravity of the module unit 30, a reasonable value, such as 1 / 3, can be set.

[0051] According to a preferred embodiment of the utility model, in a preferred embodiment of the utility model, a limiting structure 313 is provided on the sliding portion 311, and a matching structure 211 is provided on the guide rail 21, and the limiting structure 313 and the matching structure 211 are configured to be able to lock and unlock each other, and when the limiting structure 313 and the matching structure 211 are locked, the position of the sliding portion 311 relative to the guide rail 21 is limited within a preset range, for example, when the limiting structure 313 and the matching structure 211 are locked, the positions of the sliding portion 311 and the guide rail 21 remain fixed, that is, after locking, the sliding portion 311 cannot slide relative to the guide rail 21.

[0052] In other embodiments of the utility model, it can also be arranged that when the limiting structure 313 and the matching structure 211 are locked, the sliding of the sliding part 311 along the guide rail 21 is limited to a preset range, that is, the sliding part 311 can slide relative to the guide rail 21 within the preset range, which can prevent the module unit 30 from being suspended in the air relative to the mounting frame 20 too much, and prevent the capacitor cabinet 1 from tipping over or the module unit 30 from falling. For example, when the limiting structure 313 and the matching structure 211 are locked, the suspension range of the module unit 30 relative to the mounting frame 20 in the extension direction of the guide rail 21 is not greater than 1 / 2 of the length of the module unit 30 in the extension direction of the guide rail 21.

[0053] According to a preferred embodiment of the utility model, the limiting structure 313 is arranged on the side of the sliding part 311. When the connecting frame 31 includes two sliding parts 311, the limiting structure 313 can be arranged on the side of both sliding parts 311, or on the side of one of the sliding parts 311. Part of the structure in the limiting structure 313 protrudes from the sliding part 311 (in the height direction), and the matching structure 211 is arranged as a groove or a through groove. When the limiting structure 313 and the matching structure 211 are locked, the part of the structure in the limiting structure 313 protruding from the sliding part 311 can be embedded in the groove or the through groove, and the sliding range of the limiting structure 313 along the guide rail 21 is limited within the range of the matching structure 211, thereby limiting the sliding range of the module unit 30 relative to the mounting frame 20.

[0054] Specifically, Figure 4 The structure of the limiting structure 313 in a preferred embodiment of the present utility model is shown below. Figure 4 The limiting structure 313 is described.

[0055] like Figure 4As shown, the limiting structure 313 includes an elastic member 3131, a guide portion 3132 and a locking portion 3133, wherein the guide portion 3132 and the locking portion 3133 are both connected to the elastic member 3131, and the elastic member 3131 is preferably a spring sheet, which simplifies the limiting structure 313. The guide portion 3132 protrudes from the sliding portion 311, and the guide portion 3132 has an inclined surface. When the sliding portion 311 slides along the guide rail 21 toward the direction close to the mounting frame 20, the guide portion 3132 approaches the sliding portion 311, and the elastic member 3131 is compressed. For example, when the module unit 30 is pushed from the outside to the inside, the part of the guide rail 21 that is not provided with the matching structure 211 or the extruding guide portion 3132, the elastic member 3131 is compressed, and the inclined surface of the guide portion 3132 can reduce the resistance.

[0056] The locking portion 3133 also protrudes from the sliding portion 311, preferably the other side of the guide portion 3132, for example, the guide portion 3132 faces the inside of the mounting frame 20 and has an inclined surface, and the locking portion 3133 faces the outside of the mounting frame 20 and has a vertical surface or a barb at an acute angle. The elastic member 3131 is configured to enable the locking portion 3133 to be embedded in the matching structure 211.

[0057] For example, one end of the guide rail 21 close to the inner side of the mounting frame 20 has a matching structure 211, and the matching structure 211 is a groove or a through groove. When the module unit 30 is installed, the module unit 30 is pushed from the outside to the inside, the inclined surface of the guide portion 3132 is squeezed, and the elastic member 3131 is compressed, so that the module unit 30 can continue to be pushed inward. When the module unit 30 is pulled outward, the locking portion 3133 slides to the position of the groove or the through groove of the matching structure 211. Under the action of the elastic member 3131, the locking portion 3133 protrudes from the sliding portion 311 and is confined within the range of the groove or the through groove.

[0058] When the module unit 30 needs to be completely removed from the mounting frame 20 , the elastic member 3131 can be squeezed by pressing the locking portion 3133 so that the module unit 30 can be pulled out from the mounting frame 20 .

[0059] According to a preferred embodiment of the utility model, the capacitor cabinet 1 further includes a connection bus (not shown in the figure), and among the multiple module units 30 of the capacitor cabinet 1, the electrical components 32 in at least one module unit 30 are detachably connected to the connection bus. The module unit 30 in this embodiment can be removed from the mounting frame 20, or can slide relative to the mounting frame 20, and a certain margin needs to be provided for the cables. The electrical components 32 therein are preferably arranged to be detachably connected to the connection bus. When it is necessary to remove or slide one of the module units 30, the electrical components 32 therein can be removed from the connection bus, thereby reducing the amount of cables used and facilitating the optimization of space utilization in the capacitor cabinet 1.

[0060] like Figure 2As shown, in a preferred embodiment of the utility model, the electrical components 32 in the module unit 30 include a reactance 321 and a capacitor 322. The reactance 321 and the capacitor 322 are the most commonly used electrical components in the capacitor cabinet 1. In this embodiment, in a module unit 30, the capacitor 322 is arranged in the middle of the connecting frame 31, and the reactance 321 is arranged on the outside of the capacitor 322. This arrangement includes both the reactance 321 and the capacitor 322 in the same module unit 30, which can improve the utilization rate of the internal space of the capacitor cabinet 1.

[0061] Finally, it should be noted that the above description is only an embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
