Description

Technical Field

[0001] This application relates to the field of power equipment, and in particular to a distribution cabinet for an application terminal integrated bus system. Background Technology

[0002] As a core device for power distribution, operation control, safety protection, and parameter monitoring, the distribution box plays an irreplaceable role in ensuring the safe and stable operation of the power system. In operation, external input current is collected via the busbars inside the distribution box and then connected to various electrical devices through the on / off control of load switches, thereby completing the directional transmission and distribution of electrical energy.

[0003] In practical applications, the number of current phases required varies depending on the power consumption scenario. In scenarios involving low-power electrical equipment, single-phase current is typically used; while in scenarios involving high-power electrical equipment, three-phase current is required to meet the load demand.

[0004] However, the distribution boxes in the relevant technologies have the problem of single function. That is, after the corresponding load switches are designed according to the distribution of load equipment, it is difficult to adjust them. When users need to adjust the number and phase type of load switches due to changes in power consumption scenarios, they need to replace or add distribution boxes to meet power demand. This increases the user's equipment purchase cost and also causes the original equipment to be idle and resources to be wasted. Utility Model Content

[0005] To improve the adaptability of distribution boxes in different usage scenarios, this application provides a distribution cabinet that integrates a busbar system for application terminals.

[0006] This application provides a power distribution cabinet for an integrated busbar system in an application terminal, which adopts the following technical solution:

[0007] A distribution cabinet for an application terminal integrated busbar system includes a cabinet, a busbar support base, a busbar copper busbar group, a current-leading copper busbar group, a load switch, and an incoming line switch.

[0008] The busbar support includes a mounting base, which is disposed inside the enclosure and has multiple mounting slots; the busbar copper busbar assembly includes a live busbar and a neutral busbar, and the mounting slots are used to install the live busbar or the neutral busbar.

[0009] Therefore, the current-leading copper busbar group includes a live wire current-leading copper busbar and a neutral wire current-leading copper busbar, both of which are installed on the busbar support base; the live wire current-leading copper busbar is electrically connected to the live wire busbar, and the neutral wire current-leading copper busbar is electrically connected to the neutral wire busbar;

[0010] The load switch is installed inside the enclosure. The live busbar and the neutral busbar are electrically connected to the load switch. The load switch is used to control the circuit on / off of the electrical equipment.

[0011] The incoming line switch is installed inside the enclosure. The live wire busbar and the neutral wire busbar are electrically connected to the incoming line switch, and the incoming line switch is used to control the on / off of the main power supply of the distribution cabinet.

[0012] By adopting the above technical solution, when the replacement of electrical equipment requires adjustment of the corresponding load switch, the distribution box can be adapted to accommodate different numbers of single-phase and three-phase load switches by adjusting the number and position of the live busbar and neutral busbar on the mounting base, thus improving the applicability of the distribution box.

[0013] Optionally, the busbar support base further includes a connecting seat, and a support frame is provided inside the housing. The connecting seat is connected to the support frame. The mounting seat is inserted into the connecting seat so that the mounting seat is installed on the support frame.

[0014] By adopting the above technical solution, after the connecting seat is connected to the support frame, the mounting seat is inserted into the connecting seat, allowing the mounting seat to be installed on the support frame. Furthermore, when the mounting seat needs to be replaced, the insertion method allows for easy removal from the support frame, improving replacement efficiency.

[0015] Optionally, it also includes multiple adapter copper busbars; the adapter copper busbars are disposed on the connector, and the multiple adapter copper busbars correspond to the live wire lead copper busbar and the neutral wire lead copper busbar respectively; one end of the adapter copper busbar is electrically connected to the live wire lead copper busbar or the neutral wire lead copper busbar, and the other end is electrically connected to the incoming line switch.

[0016] By adopting the above technical solution, since different incoming line switches have certain differences, when it is necessary to replace the incoming line switch, the possibility of replacing the entire live wire lead copper busbar and neutral wire lead copper busbar is reduced by replacing the adapter copper busbar with the incoming line switch.

[0017] Optionally, the live wire lead copper busbar is disposed on the side of the mounting base away from the mounting groove. The mounting groove is provided with a connection hole, and a conductive piece is disposed in the connection hole. The conductive piece abuts against the live wire lead copper busbar and the live wire busbar respectively, so that the live wire busbar and the live wire lead copper busbar are electrically connected.

[0018] By adopting the above technical solution, when multiple live wire lead copper busbars are installed on the mounting base, the connection hole corresponds to one live wire lead copper busbar, so that the live wire busbar is only electrically connected to one live wire lead busbar in the mounting groove, thereby improving the stability of the distribution box operation.

[0019] Optionally, the mounting base includes multiple limiting partitions, and the mounting groove is located between two adjacent limiting partitions; the limiting partitions are provided with limiting grooves, and the neutral wire lead copper busbar is located in the limiting groove.

[0020] By adopting the above technical solution, the neutral wire lead copper busbar is installed in the limiting groove, so that the neutral wire lead copper busbar and the live wire lead copper busbar are not on the same side, thereby reducing the width of the mounting base and thus reducing the volume of the distribution cabinet.

[0021] Optionally, the mounting base further includes a support block, which is inserted into the limiting partition and is located within the mounting groove; the support block is used to support the neutral busbar.

[0022] By adopting the above technical solution, when the installation slot needs to install the neutral busbar, after the support block is inserted into the installation slot, the support block can support the neutral busbar, thereby improving the stability of the connection between the neutral busbar and the neutral lead copper busbar.

[0023] Optionally, a protective cover may also be included, which snaps into the mounting base.

[0024] By adopting the above technical solution, after the protective cover is snapped into the mounting base, it can protect the busbar copper busbar assembly and the current-carrying copper busbar assembly, reducing the possibility of damage to the busbar copper busbar assembly and the current-carrying copper busbar assembly.

[0025] Optionally, the protective cover is provided with heat dissipation holes.

[0026] By adopting the above technical solution, the heat dissipation holes further improve the heat dissipation effect of the power distribution cabinet.

[0027] Optionally, the mounting base includes multiple placement seats, with adjacent placement seats being spliced ​​together.

[0028] By adopting the above technical solution, the mounting base is assembled from multiple mounting bases, thereby enabling the adjustment of the number and position of the live busbar and the neutral busbar, which in turn allows the distribution box to install load switches of different numbers and phases.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Install live wire busbars or neutral wire busbars separately through the mounting slots. When the electrical equipment is replaced and the corresponding load switch needs to be adjusted, the number and position of live wire busbars and neutral wire busbars on the mounting base can be adjusted to make the distribution box adaptable to different numbers of single-phase load switches and three-phase load switches, thus improving the applicability of the distribution box.

[0031] 2. After connecting to the support frame via the connector, the mounting base is inserted into the connector, allowing it to be installed on the support frame. Furthermore, the insertion method allows for easy removal of the mounting base from the support frame when replacement is needed, improving replacement efficiency.

[0032] 3. By setting a limiting groove, the neutral wire lead copper busbar is installed in the limiting groove, so that the neutral wire lead copper busbar and the live wire lead copper busbar are not on the same side, thereby reducing the width of the mounting base and thus reducing the volume of the distribution cabinet.

Detailed Implementation

[0045] The following is in conjunction with the appendix Figures 1-11 This application will be described in further detail.

[0046] Example 1

[0047] Embodiment 1 of this application discloses a power distribution cabinet for an application terminal integrated bus system. For example... Figure 1 and Figure 2 As shown, a distribution cabinet for an integrated busbar system includes a cabinet 1, a busbar support base 2, a busbar copper busbar group 3, a current-carrying copper busbar group 4, a load switch 5, an incoming line switch 6, and a protective cover 8. A support frame 11 is fixedly connected inside the cabinet 1.

[0048] like Figure 3 and Figure 4 As shown, the busbar copper busbar group 3 includes a live wire busbar 31 and a neutral wire busbar 32, and the current-guiding copper busbar group 4 includes a live wire current-guiding copper busbar 41 and a neutral wire current-guiding copper busbar 42. In this embodiment 1, the live wire busbar 31 is straight, the neutral wire busbar 32 is protruding, there are three live wire current-guiding copper busbars 41, and one neutral wire current-guiding copper busbar 42.

[0049] like Figure 2 and Figure 4 As shown, the busbar support 2 includes a mounting base 21, a connecting base 22, and a support block 23. The mounting base 21 is equipped with a connecting base 22 at both ends. The connecting base 22 includes a first connecting block 221 and a second connecting block 222. The first connecting block 221 is connected to the support frame 11 by bolts, and the first connecting block 221 is connected to the second connecting block 222 by bolts.

[0050] like Figure 5 and Figure 6 As shown, in this embodiment 1, the mounting base 21 includes multiple placement seats, namely a first placement seat 211, a second placement seat 212, and a third placement seat 213. Multiple limiting partitions 215 are fixedly connected to the first placement seat 211, and mounting grooves 214 are formed between adjacent limiting partitions 215, for a total of three mounting grooves 214. A connecting hole 217 is provided on the first placement seat 211, located within the mounting groove 214. A splicing block 24 is fixedly connected to one side of the first placement seat 211, and a splicing groove 25 is provided on the other side.

[0051] like Figure 7 and Figure 8 As shown, a plug-in slot 2151 is provided on the side of the limiting partition 215 near the mounting groove 214. The plug-in block 231 is fixedly connected to the support block 23. By inserting the plug-in block 231 into the plug-in slot 2151, the support block 23 can be installed in the mounting groove 214. A limiting groove 2152 is also provided on the limiting partition 215 for placing the neutral busbar 42. After the support block 23 is installed in the mounting groove 214, the neutral busbar 32, the neutral busbar 42 and the support block 23 are connected by bolts, so that the neutral busbar 32 and the neutral busbar 42 are electrically connected. At the same time, the support block 23 can support the neutral busbar 32, thereby improving the stability of the connection between the neutral busbar 32 and the neutral busbar 42.

[0052] Furthermore, such as Figure 6 and Figure 7 As shown, a fixing seat 218 is fixedly connected between two adjacent mounting slots 214 on the first placement seat 211. When the neutral wire lead copper bus 42 is placed in the limiting slot 2152, the fixing seat 218 is connected to the neutral wire lead copper bus 42 by bolts, thereby fixing the neutral wire lead copper bus 42 to the first placement seat 211 and reducing the possibility of the neutral wire lead copper bus 42 moving.

[0053] like Figure 6 As shown, the structure of the second placement seat 212 differs from that of the first placement seat 211 in that the second placement seat 212 has two connecting holes 217, which are located in two spaced mounting slots 214. The structure of the third placement seat 213 differs from that of the first placement seat 211 in that the third placement seat 213 has only one mounting slot 214, in which a support block 23 is installed.

[0054] It should be noted that, as Figure 3 and Figure 6As shown, in this embodiment 1, the mounting base 21 includes two first placement bases 211, two second placement bases 212, and one third placement base 213. Specifically, the first placement bases 211, second placement bases 212, first placement bases 211, second placement bases 212, and third placement bases 213 are assembled in sequence. After the first placement bases 211, second placement bases 212, and third placement bases 213 are assembled into the mounting base 21 by corresponding splicing blocks 24 and splicing grooves 25, the connection holes 217 on the mounting base 21 are arranged at intervals. The mounting grooves 214 with connection holes 217 are used to install the live wire busbars 31. After the support block 23 is inserted into the mounting groove 214 between two live wire busbars 31, it is used to install the neutral wire busbars 32.

[0055] At the same time, such as Figure 3 and Figure 4 As shown, three live wire lead-in copper busbars 41 are located on the side of the mounting base 21 away from the mounting groove 214. The three live wire lead-in copper busbars 41 are arranged side by side, and the connection holes 217 on the mounting base 21 correspond to one live wire lead-in copper busbar 41 in sequence along the length of the mounting base 21. After the live wire busbar 31 is installed in the mounting groove 214, a conductive piece 9 is placed in the connection hole 217. After the live wire lead-in copper busbars 41, the live wire busbar 31, and the conductive piece 9 are fixed by bolts, the live wire lead-in copper busbars 41 and the live wire busbar 31 are electrically connected. In addition, the live wire lead-in copper busbars 41 and the neutral wire lead-in copper busbars 42 are installed on different sides. Compared with the prior art where the live wire lead-in copper busbars 41 and the neutral wire lead-in copper busbars 42 are arranged side by side, the installation method of this application reduces the width of the mounting base 21, thereby reducing the volume of the distribution cabinet.

[0056] like Figure 2 As shown, a ventilation slot 216 is formed between the first placement seat 211, the second placement seat 212 and the third placement seat 213. The ventilation slot 216 helps the busbar copper busbar group 3 to dissipate heat during operation, thereby improving the stability of the distribution box during operation.

[0057] like Figure 2 and Figure 5 As shown, the first connecting block 221 is also provided with a splicing block 24 and a splicing groove 25, allowing the mounting base 21 to be spliced ​​with the first connecting block 221, thereby mounting the mounting base 21 on the support frame 11. Simultaneously, after the second connecting block 222 is connected to the first connecting block 221, the neutral wire busbar 42 is located between the first connecting block 221 and the second connecting block 222. The second connecting block 222 can restrict the movement of the neutral wire busbar 42, thereby reducing the possibility of the mounting base 21 moving. When the mounting base 21 needs to be replaced, the splicing method between the mounting base 21 and the connecting block 22 allows the mounting base 21 to be easily removed from the support frame 11, improving replacement efficiency.

[0058] like Figure 1 and Figure 3 As shown, the ends of the live wire lead-in copper busbar 41 and the neutral wire lead-in copper busbar 42 furthest from the busbar copper busbar group 3 are respectively connected to a transition copper busbar 7. The live wire lead-in copper busbar 41 and the neutral wire lead-in copper busbar 42 are each connected to a transition copper busbar 7 by bolts to achieve electrical connection. The end of the transition copper busbar 7 furthest from the mounting base 21 is used to connect to the incoming switch 6. After the external current enters the distribution box, it first passes through the incoming switch 6, then through the transition copper busbar 7, and then enters the corresponding live wire lead-in copper busbar 41 or neutral wire lead-in copper busbar 42. The incoming switch 6 controls the overall power supply of the entire distribution box. In addition, the live wire lead-in copper busbar 41 is electrically connected to the live wire busbar 31, and the neutral wire lead-in copper busbar 42 is electrically connected to the neutral wire busbar 32. The single-phase load switch 5 is electrically connected to one live wire busbar 31 and one neutral wire busbar 32, thereby realizing the on / off control of the single-phase load electrical equipment by the single-phase load switch 5.

[0059] Since different incoming line switches have certain differences, when it is necessary to replace the incoming line switch 6, the possibility of replacing the entire live wire lead copper busbar 41 and neutral wire lead copper busbar 42 is reduced by replacing the adapter copper busbar 7 with the one that is compatible with the incoming line switch 6.

[0060] like Figure 1 and Figure 9 As shown, a protective cover 8 is also installed on the mounting base 21. The protective cover 8 has a clip 82, which engages with the mounting base 21, facilitating its removal. The protective cover 8 protects the busbar copper busbar group 3 and the current-carrying copper busbar group 4, reducing the possibility of damage. Furthermore, the protective cover 8 has multiple heat dissipation holes 81, improving the heat dissipation of the busbar copper busbar group 3 and the current-carrying copper busbar group 4, further enhancing the stability of the distribution box during operation. The protective cover 8 has mounting holes 83. When installing the load switch 5, after inserting the neutral busbar 32 and the live busbar 31 into the load switch 5, the installation tool extends through the mounting hole 83 and operates the bolts on the load switch 5 to electrically connect the load switch 5 with the neutral busbar 32 and the live busbar 31. The operation is simple.

[0061] The implementation principle of a power distribution cabinet for an application terminal integrated bus system in Embodiment 1 of this application is as follows:

[0062] During installation, firstly, connect the connector 22, first placement seat 211, second placement seat 212 and third placement seat 213 in sequence to form the busbar support seat 2. Then, install the live wire busbar 31, neutral wire busbar 32, neutral wire current-leading copper busbar 42 and live wire current-leading copper busbar 41 into the busbar support seat 2, and then snap the protective cover 8 onto the busbar support seat 2.

[0063] Then, the connecting seat 22 is connected to the support frame 11 with bolts, so that the busbar support seat 2 is installed on the support frame 11. After the busbar support seat 2 is installed, the incoming line switch 6 is installed, and the load switch 5 is installed as needed.

[0064] In this embodiment 1, the live wire busbar 31 and the neutral wire busbar 32 are alternately arranged in multiple mounting slots 214, so that each live wire busbar 31 is electrically connected to a live wire lead copper busbar 41, and each neutral wire busbar 32 is electrically connected to a neutral wire lead copper busbar 42. Thus, when the load switch 5 of the single-phase load device is connected to a live wire busbar 31 and a neutral wire busbar 32, three-phase current is used to supply power to the single-phase load device.

[0065] Example 2

[0066] The difference between Example 2 and Example 1 is as follows:

[0067] like Figure 10 and Figure 11 As shown, the mounting base 21 also includes a fourth placement base 219. The structure of the fourth placement base 219 differs from that of the first placement base 211 in that the fourth placement base 219 is provided with three connecting holes 217, which are located in three mounting slots 214 respectively.

[0068] like Figure 10 and Figure 11 As shown, in this embodiment 2, the mounting base 21 includes a first placement base 211, a second placement base 212, a third placement base 213, and two fourth placement bases 219. Specifically, the mounting base 21 is assembled in the order of fourth placement base 219, first placement base 211, second placement base 212, fourth placement base 219, and third placement base 213. Simultaneously, the connection holes 217 on the mounting base 21 correspond sequentially to three live wire busbars 41 along the length of the mounting base 21. The fourth placement bases 219 allow the three live wire busbars 31 to be placed adjacent to each other, thus enabling connection to a load switch 5 suitable for three-phase load equipment.

[0069] The implementation principle of a power distribution cabinet for an application terminal integrated bus system in Embodiment 2 of this application is as follows:

[0070] By sequentially assembling the first placement seat 211, the second placement seat 212, the third placement seat 213, and the fourth placement seat 219, the distribution box can simultaneously connect to the load switches 5 of single-phase and three-phase load devices, thus making it suitable for different electrical equipment and different power consumption scenarios, meeting different power needs, and improving the applicability of the distribution box.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
