Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electric power equipment, and specifically relates to a module assembly and an electric power module system. Background Art
[0002] The power module is a key device for realizing system power distribution and power supply. In order to improve the reliability of operation, the power module is generally integrated with an uninterruptible power supply (UPS), which is an uninterruptible power supply with energy storage device. It is mainly used to provide uninterruptible power supply to some equipment with high requirements for power supply stability. When the mains input is normal, the UPS stabilizes the mains and supplies it to the load. At this time, the UPS is an AC voltage stabilizer, and it also charges the battery inside the machine; when the mains power is interrupted (accidental power outage), the UPS immediately switches the DC power of the battery to the load through the inverter switching conversion method to continue to supply 220V AC power to the load, so that the load maintains normal operation and protects the load software and hardware from damage.
[0003] The power module also integrates a bypass module, which is a power supply guarantee module that bypasses the UPS and directly provides the power signal to the load when the UPS equipment fails, is repaired or upgraded. The bypass module has a power input and output interface. Its main function is to monitor the working status of the UPS and switch the input and output signals to achieve rapid switching between the UPS and the load, thereby ensuring continuous power supply to the load; at the same time, the bypass module can also monitor and filter the input power parameters such as voltage and frequency to protect the load from interference and fluctuations of the power grid.
[0004] Since the power connection structure (such as copper busbar) in the bypass module is connected to the power connection structure (such as copper busbar) in the power module through threaded connectors, the power module and the bypass module need to be powered off before the bypass module can be removed for maintenance. Similarly, the bypass module can only be powered on after installation, which makes disassembly and maintenance cumbersome and inefficient. Utility Model Content

[0037] In the claims, specification and the above drawings of the utility model, unless otherwise clearly defined, if the term "fixed connection" or "fixed connection" is used, it should be understood in a broad sense, that is, any connection method without a displacement relationship and relative rotation relationship between the two, that is to say, including non-detachable fixed connection, detachable fixed connection, integrated connection and fixed connection through other devices or elements.
[0038] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".
[0039] Please also read Figures 1 to 7 , the module assembly provided by the utility model is now described. The module assembly includes a main body 1, a first contact finger 2, a second contact finger 3 and a bypass module 4; the main body 1 has a plug-in channel 101 extending in the front-to-back direction, and the first contact finger 2 and the second contact finger 3 are both arranged at the rear end of the plug-in channel 101; the bypass module 4 is slidably matched with the plug-in channel 101, and the bypass module 4 has a first conductive row 410 and a second conductive row 420 extending backward, and the rear end of the first conductive row 410 can be plugged and electrically conductive with the first contact finger 2 in the front-to-back direction, and the rear end of the second conductive row 420 can be plugged and electrically conductive with the second contact finger 3 in the front-to-back direction.
[0040] In this embodiment, the main body 1 is exemplarily shown as a UPS module, and the bypass module 4 corresponds to a UPS bypass module. Of course, the main body 1 and the bypass module 4 can also be other modules with similar functional requirements, which are not limited here.
[0041] In this embodiment, the first conductive bar 410 and the second conductive bar 420 may be copper bars, or other conductive connecting bars that can meet the requirements of conductivity and assembly, which is not limited here.
[0042] In this embodiment, the first contact finger 2 and the second contact finger 3 are electrically connected to other devices in the main body 1 through conductive structures (such as conductive connection rows). After the first contact finger 2, the second contact finger 3, the first conductive row 410 and the second conductive row 420 are plugged in and conductive, the bypass module 4 and the main body 1 can form a closed conductive loop to meet the electrical connection requirements.
[0043] Compared with the prior art, the module assembly provided in this embodiment has the following characteristics: under normal working conditions, the first conductive row 410 is plugged into the first contact finger 2 for electrical conduction, and the second conductive row 420 is plugged into the second contact finger 3 for electrical conduction; if the bypass module 4 needs to be removed, the bypass module 4 is directly pulled out forward, at which time the first conductive row 410 is detached forward from the first contact finger 2, and the second conductive row 420 is detached forward from the second contact finger 3; if the bypass module 4 needs to be installed, the bypass module 4 is pushed backward in alignment with the plug-in channel 101 until the first conductive row 410 is reinserted backward into the first contact finger 2, and the second conductive row 420 is reinserted backward into the second contact finger 3, and the installation is completed. In the module assembly of the present embodiment, when the bypass module 4 is disassembled and assembled, there is no need for the operator to touch the conductive connection area between the bypass module 4 and the main body 1, and the disassembly and assembly can be achieved by plugging and unplugging. A hot-plug conductive connection structure is formed between the first conductive row 410 and the first contact finger 2, and between the second conductive row 420 and the second contact finger 3, and finally the hot plugging of the bypass module 4 and the main body 1 is achieved, which effectively improves the disassembly and assembly efficiency and maintenance efficiency of the bypass module 4, and can also better ensure the safety of the operators.
[0044] See also Figures 3 to 6 In some embodiments, the first contact finger 2 and the second contact finger 3 are both provided with a plug-in conductive slot 5 that is open forward, and the rear ends of the first conductive row 410 and the second conductive row 420 are respectively plugged into the corresponding plug-in conductive slot 5, and the rear ends of the first conductive row 410 and the second conductive row 420 are respectively formed with a guiding slope 402. In the process of plugging the conductive row with the corresponding contact finger, the plug-in conductive slot 5 can guide the corresponding conductive row, so as to facilitate the effective conductive contact between the first conductive row 410 and the second conductive row 420 and the first contact finger 2 and the second contact finger 3, and at the same time, it can also prevent the first conductive row 410 and the second conductive row 420 from being separated from the effective conductive contact area of the first contact finger 2 and the second contact finger 3 after being plugged in place, so as to ensure the reliability of the electrical connection; in addition, the guiding slope 402 can guide the first conductive row 410 and the second conductive row 420 during the plug-in process, so as to facilitate the first conductive row 410 and the second conductive row 420 to align with the corresponding plug-in conductive slot 5.
[0045] In some embodiments, the bypass module 4 has a sliding surface 403 that fits the plug-in channel 101, and also has a mounting surface 404 that is opposite to the sliding surface 403. Figures 5 to 7 As shown, the sliding surface 403 is mainly used to fit with the plug-in channel 101 to realize the assembly of the bypass module 4 and the main body 1. A plurality of power terminal groups distributed in a direction perpendicular to the front-to-back direction are formed on the side where the mounting surface 404 is located, and each power terminal group has a first power terminal 405 and a second power terminal 406 arranged sequentially from the back to the front; the front end of the first conductive row 410 is connected to the first power terminal 405, the front end of the second conductive row 420 is connected to the second power terminal 406, and the second conductive row 420 is arranged across the first conductive row 410 in the front-to-back direction. In order to facilitate assembly, the sliding surface 403 and the mounting surface 404 are both planes.
[0046] In this embodiment, a mounting surface 404 is provided on the opposite side of the sliding surface 403, which not only meets the assembly requirements of the bypass module 4, but also makes full use of the empty area on the bypass module 4 to improve space utilization; on this basis, the first conductive bar 410 and the second conductive bar 420 both extend in the front-to-back direction, occupying a smaller space in the direction perpendicular to the front-to-back direction, and the second conductive bar 420 is arranged astride the first conductive bar 410, so that the arrangement of the first conductive bar 410 and the second conductive bar 420 is more compact, and the overall occupied space is smaller, thereby improving the space utilization between the main body 1 and the bypass module 4.
[0047] Based on the embodiment in which the main body 1 is a UPS module and the bypass module 4 is a UPS bypass module, the sliding surface 403 is the lower surface of the bypass module 4, and the mounting surface 404 is the upper surface of the bypass module 4; correspondingly, the upper surface of the bypass module 4 slides and fits with the lower wall of the plug-in channel 101, and the lower wall of the plug-in channel 101 plays a supporting role, which can improve the stability and reliability of the assembly of the bypass module 4 and simplify the assembly support structure. It should be understood that it can also be set so that the sliding surface 403 is the upper surface of the bypass module 4 and the mounting surface 404 is the lower surface of the bypass module 4, or the sliding surface 403 and the mounting surface 404 are distributed in the left and right directions, which can meet the plug-in assembly requirements.
[0048] Based on the above embodiments, see Figures 4 to 7, the board surface of the first conductive row 410 is parallel to the mounting surface 404, and the plug-in conductive slot 5 on the first contact finger 2 extends in a direction parallel to the mounting surface 404; the board surface of the second conductive row 420 is perpendicular to the mounting surface 404, and the plug-in conductive slot 5 on the second contact finger 3 extends in a direction perpendicular to the mounting surface 404. In this embodiment, the first conductive row 410 and the second conductive row 420 are arranged in a vertical distribution form, and correspondingly, the first contact finger 2 and the second contact finger 3 are also arranged in a vertical distribution form, which further improves the compactness of the distribution between the first conductive row 410 and the second conductive row 420, and between the first contact finger 2 and the second contact finger 3. At the same time, it can effectively avoid the problem of mutual interference between the conductive rows and between the contact fingers, reserve a certain safety space, and ensure the reliability of use.
[0049] For more details, see Figures 4 to 7 In order to realize the cross-layout of the second conductive bar 420 and meet the plug-in adaptation with the second contact finger 3, the second conductive bar 420 is located above the first conductive bar 410, and the second contact finger 3 is located above the first contact finger 2; the second conductive bar 420 includes a front wiring board 421, a jumper board 422, a transition board 423 and a rear wiring board 424 connected in sequence from front to back; the jumper board 422 and the rear wiring board 424 both extend in the front-to-back direction; the front wiring board 421 and the transition board 423 are both perpendicular to the front-to-back direction and extend to the same side of the jumper board 422; the rear wiring board 424 is plugged into the plug-in conductive slot 5 on the second contact finger 3. The first conductive bar 410 is closer to the mounting surface 404, which can further reduce the space occupied by the first conductive bar 410 and the second conductive bar 420 in the direction perpendicular to the mounting surface 404, and further improve the compactness of the structure.
[0050] In some embodiments, the middle of the second conductive row 420 is further connected to an insulating support member 430, see Figure 1 , Figure 2 , Figures 5 to 7, the support member 430 is supported on the mounting surface 404. Since the second conductive bar 420 is longer, by providing the support member 430, the collapse and tilting of the second conductive bar 420 can be effectively avoided, and it can be accurately plugged and adapted with the second contact finger 3. In this embodiment, on the same second conductive bar 420, the number of support members 430 is shown as one, but it should be understood that the number of support members 430 is set according to the size of the second conductive bar 420, and it is sufficient to meet the support requirements, and it is not limited here; in addition, the implementation method of the support member 430 includes but is not limited to glass fiber reinforced plastic components, etc., which can meet the requirements of strength and insulation. Specifically, in order to adapt to the assembly of the jumper plate 422 in the mounting surface 404 and the second conductive bar 420, and at the same time meet the requirements of a simple and compact structure, the support member 430 is an L-shaped member, one arm of which is connected to the jumper plate 422 by a fastener, and the other arm is connected to the mounting surface 404 by a fastener.
[0051] Similarly, a support member may be disposed in the middle of the first conductive bar 410 to prevent the first conductive bar 410 from collapsing or tilting.
[0052] In some embodiments, the main body 1 may be used as follows Figures 1 to 4 In the structure shown, the main body 1 includes a main frame 110, a limiting guide rail 120, a main body limiting member 130 and a main control box 140; a plug-in opening is formed on the front side of the main frame 110, and electrical components are also installed in the main frame 110; the limiting guide rail 120 and the main control box 140 are arranged inside the main frame 110, and a plug-in channel 101 is formed therebetween; the main body limiting member 130 is arranged at the rear end of the plug-in channel 101 to limit the insertion depth of the bypass module 4, and when the corresponding position of the rear part of the bypass module 4 abuts against the main body limiting member 130, the first conductive row 410 and the first contact finger 2 are plugged in place, and the second conductive row 420 and the second contact finger 3 are plugged in place. More specifically, a supporting plate is provided at the bottom between the limiting guide rail 120 and the main control box 140, and the supporting plate can support the bypass module 4. The limiting guide rail 120 and the main control box 140 are respectively limited on both sides of the bypass module 4 to ensure the stability of the plugging and unplugging movement of the bypass module 4; at the same time, the insertion depth of the bypass module 4 is limited by the main body limiting member 130 to avoid damage to the first contact finger 2 and the second contact finger 3 due to excessive insertion depth; and, in this embodiment, the main control box 140 is used for limiting, and the limiting guide rail 120 is only provided on one side of the plugging and unplugging channel 101, which simplifies the layout of the limiting structure to the greatest extent and further improves the compactness of the structure.
[0053] During specific implementation, the main body limiting member 130 is a flange structure integrally formed with the supporting plate.
[0054] See also Figure 1 , Figure 2 , Figures 4 to 7In some embodiments, in order to cooperate with the main body 1 and improve the compactness of the structure, the bypass module 4 further includes a module bracket 440, a heat sink 450 and a functional unit 460. The module bracket 440 is slidably matched with the plug-in channel 101 to form a sliding surface 403; the heat sink 450 is disposed on the module bracket 440 to form a mounting surface 404; the functional unit 460 is disposed on the mounting surface 404 to form a first power connection terminal 405 and a second power connection terminal 406. The heat sink 450 can effectively dissipate heat for the functional unit 460 to ensure that the functional unit 460 can operate normally.
[0055] On the premise that bypass module 4 is a UPS bypass module, see Figure 1 , Figure 2 , Figures 5 to 7 The functional unit 460 includes a power device 461 and a filter device 462. The filter device 462 is arranged in the front of the module bracket 440, and the power device 461 is arranged on the mounting surface 404 formed by the heat sink 450, and the power device 461 is located behind the filter device 462; the power device 461 and the filter device 462 are conductively connected through the third conductive row 463, the rear end of the power device 461 forms a first power terminal 405, and the filter device 462 forms a second power terminal 406.
[0056] In some specific embodiments, three functional units 460 are provided along the left and right directions, corresponding to the three-phase circuits respectively, and each functional unit 460 is provided with a first conductive row 410 and a second conductive row 420. It should be understood that the number of functional units 460 is related to the actual power supply requirements and is not limited here. More specifically, the filter components 462 in each functional unit 460 are integrated into one.
[0057] In order to achieve locking with the main body 1 and the bypass module 4 and meet the heat dissipation requirements of the bypass module 4, in some embodiments, a fan plate 442 is formed on the front side of the module bracket 440, wherein the fan plate 442 provides an air inlet opening for the fan of the radiator 450; the fan plate 442 is detachably connected to the front side of the main frame 110 by fasteners (such as threaded fasteners). In this embodiment, the fan plate 442 is connected to the main frame 110, and there is no need to set up an additional connection platform, which further improves the overall structural compactness of the bypass module 4.
[0058] Based on the above embodiments, see Figure 5The rear end of the module bracket 440 is bent to form a limit flange 441, and the rear side of the limit flange 441 can abut against the main body limiter 130. By providing the limit flange 441, the contact area between the module bracket 440 and the main body limiter 130 is increased, which not only improves the reliability of the front and rear limit, but also avoids the problem of easy bumping and damage due to too small contact area between the module bracket 440 and the main body limiter 130.
[0059] Based on the same inventive concept, this embodiment also provides a power module system, including the above-mentioned module assembly.
[0060] Compared with the prior art, the power module system provided in this embodiment can realize hot-swap between the bypass module and the main body by adopting the above-mentioned module assembly. When disassembling and assembling the bypass module 4, there is no need for the operator to touch the conductive connection area between the bypass module 4 and the main body 1, and the disassembly and assembly can be realized by front and back plugging. A hot-swap conductive connection structure is formed between the first conductive row 410 and the first contact finger 2, and between the second conductive row 420 and the second contact finger 3, and finally the hot-swap between the bypass module 4 and the main body 1 is realized, which effectively improves the disassembly and maintenance efficiency of the bypass module 4, and can also better ensure the safety of the operators.
