Power distribution equipment and data centers

Technical Field

This application relates to the field of computing device technology, and more particularly to a power distribution device and a data center.

Background Technology

In related technologies, devices used to power servers in data centers typically employ PDUs (Power Distribution Units). A PDU usually has multiple branch cables connected from a terminal block to each socket unit, and the server power cord connects to the server through the PDU's socket units. However, due to the limited size of the PDU, the internal cables are densely packed, and heat dissipation is poor. When operating at full load for extended periods, excessive temperature rise can occur, leading to cable burnout.

Detailed Implementation

In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

The power distribution device 1 according to an embodiment of this application will now be described with reference to Figures 1 to 12.

Figure 1 shows a structural schematic diagram of a power distribution device 1 according to an embodiment of this application, and Figure 2 shows an exploded structural schematic diagram of the power distribution device 1 according to an embodiment of this application. As shown in Figures 1 and 2, the power distribution device 1 includes a housing 10, a busbar copper bus 20, and a wiring module 40. Specifically, the housing 10 defines a receiving cavity inside. The busbar copper bus 20 is disposed in the receiving cavity and is electrically connected to the power supply cable of the power distribution equipment. The wiring module 40 is disposed in the receiving cavity and is electrically connected to the busbar copper bus 20 via an internal cable and to the power-consuming equipment via an external cable.

In this embodiment, the power distribution device 1 is used to provide power to the electrical equipment in the data center, and can also be used to supply power to switches or temporary loads. The switches provide network services to electrical equipment such as computing devices, and the temporary loads can be electronic products, lighting equipment, or any other device.

In this embodiment of the application, the number of busbar copper bus 20 can be one or more. Figure 3 shows a schematic diagram of the structure of multiple busbar copper bus 20 of the power distribution device 1 according to an embodiment of the application. As shown in Figure 3, in some optional examples of the application, the number of busbar copper bus 20 can be multiple, and the multiple busbar copper bus 20 are spaced apart in the first direction.

For example, the busbar copper bus 20 can be made of 99.9% pure electrolytic copper. The size of the busbar copper bus 20 can be set according to the total current carrying capacity of all the wiring units 41 included in the wiring module 40. The larger the total current carrying capacity, the larger the size of the busbar copper bus 20. Those skilled in the art can flexibly set it according to actual needs. This application embodiment does not make specific limitations in this regard.

In this embodiment, the wiring module 40 and the busbar copper bus 20 are spaced apart within the receiving cavity. The wiring module 40 may include multiple wiring units 41, each having a first terminal and a second terminal. The first terminal is used for electrical connection to the busbar copper bus 20 via an internal cable, and the second terminal is used for electrical connection to the electrical equipment via an external cable. This achieves electrical connection between the busbar copper bus 20 and the electrical equipment, thereby supplying power to the equipment.

According to the power distribution device 1 of the present application embodiment, by using busbar copper bus 20 as the busbar, it is beneficial to reduce the overall temperature rise of the power distribution device 1 and improve the power supply stability. On the other hand, it is beneficial to extend the working life of the power distribution device 1. Furthermore, the material of the busbar copper bus 20 can be reused, thereby reducing depreciation costs.

In one embodiment, there are multiple busbars 20, and at least two of the multiple busbars 20 are spaced apart in a first direction.

It should be noted that the first direction can be any direction, such as the vertical or horizontal direction after the power distribution device 1 is installed. That is, multiple busbar copper busbars 20 can be spaced apart vertically or horizontally.

By spacing multiple busbars 20 apart in the first direction, sufficient electrical clearance can be ensured between the multiple busbars 20. This allows for ample wiring space for multiple internal cables when wiring the multiple busbars 20 to the wiring module 40. On the one hand, this improves the convenience of wiring, and on the other hand, it reduces the probability of internal cables coming into contact with other busbars 20, thereby improving the operational reliability of the power distribution device 1.

Figure 4 shows a schematic diagram of the structure of a plurality of busbar copper busbars 20 in the power distribution device 1 of this application embodiment. As shown in Figure 4, in one embodiment, the plurality of busbar copper busbars 20 are spaced apart in a second direction, which is perpendicular to the first direction.

In this embodiment of the application, the first direction can be any direction, and the second direction can be any other direction perpendicular to the first direction.

In some examples, as shown in Figures 3 and 4, the first direction can be horizontal, specifically the length or width of the power distribution device 1; the second direction can be vertical, specifically the height of the power distribution device 1. Multiple busbars 20 are spaced apart along the length or width of the power distribution device 1, and also spaced apart along the height of the power distribution device 1.

More specifically, the structure of the busbar copper bus 20 can be flat, and the plane on which each busbar copper bus 20 is located can be perpendicular to the second direction. For example, if the second direction can be a vertical direction, then the planes on which multiple busbar copper bus 20 are located can be perpendicular to each other with the vertical direction, that is, the planes on which multiple busbar copper bus 20 are located are parallel to the horizontal plane.

In one embodiment, the plurality of busbars 20 may include one or all of a first phase busbar 21, a second phase busbar 22, a third phase busbar 23, a neutral busbar 24, and a ground busbar 25.

In some examples, the multiple busbars 20 include a first phase busbar 21, a second phase busbar 22, a third phase busbar 23, a neutral busbar 24, and a grounding busbar 25. The power distribution device 1 of this embodiment can adopt a three-phase five-wire AC power mode. Specifically, among the multiple busbars 20, three busbars 20 can be electrically connected to the three-phase power lines (L1, L2, L3) respectively to form the first phase busbar 21, the second phase busbar 22, and the third phase busbar 23; one busbar 20 can be electrically connected to the neutral line (N) to form the neutral busbar 24; and the other busbar 20 can be electrically connected to the grounding line (P) to form the grounding busbar 25. Thus, three-phase power supply can be achieved for the power distribution device 1.

Furthermore, in other examples, the power distribution device 1 can also be used for single-phase power supply. For example, any one of the first phase bus 21, the second phase bus 22, and the third phase bus 23 among the plurality of busbars 20, together with the neutral wire and the ground wire, can form a single-phase power supply.

In one embodiment, there are multiple busbars 20, each busbar 20 is provided with at least one first wiring hole, and the wiring module 40 includes at least one wiring unit 41; the first wiring terminal of each wiring unit 41 is electrically connected to one end of a plurality of internal cables through fasteners, and the other end of the plurality of internal cables is electrically connected to at least a portion of the busbars 20 through fasteners passing through the first wiring hole.

Optionally, the plurality of busbar copper busbars 20 include a neutral busbar 24 and a grounding busbar 25, and also include one or all of a first phase busbar 21, a second phase busbar 22, and a third phase busbar 23; the first terminal of each wiring unit 41 is electrically connected to one end of a plurality of internal cables through fasteners, and the other end of the plurality of internal cables is electrically connected to the first wiring hole of one or all of the first phase busbar 21, the second phase busbar 22, the third phase busbar 23, the neutral busbar 24, and the grounding busbar 25 through fasteners.

For example, the plurality of wiring units 41 include a first wiring unit and a second wiring unit. The input terminal of the first wiring unit is electrically connected to any one of the first phase bus 21, the second phase bus 22 and the third phase bus 23, the neutral bus 24 and the ground bus 25 respectively. The second wiring unit is electrically connected to the first phase bus 21, the second phase bus 22, the third phase bus 23, the neutral bus 24 and the ground bus 25 respectively.

In addition, one end of the internal cable can be electrically connected to the first end of the wiring unit 41 by plugging or snapping, and this application does not make specific limitations in this regard.

Optionally, the second terminal of each wiring unit 41 is electrically connected to one end of an external cable via a fastener, and the other end of the external cable is electrically connected to the electrical equipment.

For example, the fastener may be a metal screw, one end of the external cable is electrically connected to the second terminal via the metal screw, and the other end of the external cable extends out of the housing 10 and is electrically connected to the electrical device.

Optionally, the housing 10 is further provided with at least one outgoing cable through hole connecting the receiving cavity to the outside, and the other end of the external cable extends to the outside of the receiving cavity through the corresponding outgoing cable through hole.

For example, multiple wiring units 41 are arranged side by side in a third direction. In this embodiment, the third direction can be a direction perpendicular to the first direction and the second direction, respectively, specifically the length direction of the power distribution device 1. Multiple cable outlet holes are provided one-to-one with multiple wiring units 41, so that external cables connected to the second terminal of the wiring unit 41 can extend to the outside of the housing 10 through the corresponding cable outlet holes.

In some optional examples of this application, the other ends of multiple external cables can extend to the outside of the receiving cavity through a common through-hole. This arrangement reduces the number of through-holes on the housing 10, thus reducing the manufacturing difficulty of the housing 10.

Optionally, as shown in Figure 3, the ratio of the spacing between two adjacent busbars 20 in the first direction to the dimension of the busbar 20 in the first direction is 1 to 2.

In this embodiment, the first direction can be the width direction of the power distribution device 1 (i.e., the front-to-back direction in the figure), and the width direction of the busbar copper bus 20 is parallel to the width direction of the power distribution device 1. The dimension of the busbar copper bus 20 in the first direction can be understood as the width dimension of the busbar copper bus 20.

For example, the ratio between the spacing of two adjacent busbars 20 in the first direction and the width of the busbar 20 can be 1 to 2. Preferably, the ratio between the spacing of two adjacent busbars 20 in the first direction and the width of the busbar 20 can be 1.5.

In some specific examples, the width of the busbar copper bus 20 can be 30mm, and the spacing between two adjacent busbar copper bus 20 in the first direction can be 45mm.

It should be noted that if the spacing between two adjacent busbars 20 in the first direction is too large, for example, the ratio of the spacing to the size of the busbar 20 in the first direction is greater than 2, then multiple busbars 20 will occupy too much space in the first direction, resulting in the power distribution device 1 having an excessively large width and occupying too much installation space. If the spacing between two adjacent busbars 20 in the first direction is too small, for example, the ratio of the spacing to the size of the busbar 20 in the first direction is less than 1, then the wiring space between two adjacent busbars 20 will be too small, thus causing inconvenience to the wiring between the busbars 20 and the wiring module 40.

Therefore, by setting the ratio of the spacing between two adjacent busbars 20 in the first direction to the size of the busbar 20 in the first direction to 1 to 2, it is beneficial to reduce the external size of the power distribution device 1 and thus reduce the space occupied for installation, and it also brings convenience to the wiring between the busbars 20 and the wiring module 40.

Optionally, the ratio of the spacing between two adjacent busbars 20 in the second direction to the dimension of the busbar 20 in the second direction is 3 to 7.

In this embodiment, the second direction can be the height direction of the power distribution device 1 (i.e., the up and down direction in the figure), the thickness direction of the bus copper bus 20 is parallel to the height direction of the power distribution device 1, and the dimension of the bus copper bus 20 in the second direction can be the thickness dimension of the bus copper bus 20.

For example, the ratio between the spacing of two adjacent busbars 20 in the second direction and the height of the busbar 20 can be 3 to 7. Preferably, the ratio between the spacing of two adjacent busbars 20 in the second direction and the height of the busbar 20 can be 5.

In some specific examples, the thickness of the busbar copper bus 20 can be 5 mm, and the spacing between two adjacent busbar copper bus 20s in the second direction can be 25 mm.

It should be noted that if the spacing between two adjacent busbars 20 in the second direction is too large, for example, the ratio of the spacing to the size of the busbar 20 in the second direction is greater than 7, then multiple busbars 20 will occupy too much space in the second direction, resulting in an excessively large height of the power distribution device 1 and occupying too much installation space. If the spacing between two adjacent busbars 20 in the second direction is too small, for example, the ratio of the spacing to the size of the busbar 20 in the second direction is less than 3, then the wiring space between two adjacent busbars 20 will be too small, thus causing inconvenience to the wiring between the busbars 20 and the wiring module 40.

Therefore, by setting the ratio of the spacing between two adjacent busbars 20 in the second direction to the size of the busbar 20 in the second direction to 3 to 7, it is beneficial to reduce the external size of the power distribution device 1 and thus reduce the space occupied for installation, and it also brings convenience to the wiring between the busbars 20 and the wiring module 40.

In one embodiment, the busbar copper bus 20 is further provided with a second wiring hole for electrical connection with the power distribution cable of the power distribution equipment via fasteners.

For example, the second wiring hole can be located near the edge of the busbar copper bus 20 to reduce the length of the power distribution cable extending into the receiving cavity and improve the convenience of wiring. The fastener can be a conductive metal component, such as a metal screw.

Figure 5 shows a structural schematic diagram of the mounting base 30 of the power distribution device 1 according to an embodiment of this application, and Figure 6 shows a schematic diagram of a plurality of busbar copper busbars 20 fixedly connected on the mounting base 30. In one embodiment, as shown in Figures 5 and 6, the power distribution device 1 further includes at least one mounting base 30, which is mounted on the housing 10 and used to support the busbar copper busbars 20.

For example, the mounting base 30 includes a plurality of support columns 32a corresponding to a plurality of busbar copper busbars 20, the busbar copper busbars 20 being connected to the ends of the corresponding support columns 32a, wherein the plurality of support columns 32a have different lengths in a second direction.

Optionally, the mounting base 30 includes a first bearing portion 31 and a second bearing portion 32. The first bearing portion 31 is connected to the housing 10, and the second bearing portion 32 is connected to the first bearing portion 31. The second bearing portion 32 is used to support the busbar copper bus 20.

For example, the fixing seat 30 is disposed in the receiving cavity and is fixedly connected to the housing 10 by fasteners. The fixing seat 30 may include a first support portion 31 and a second support portion 32. The first support portion 31 is fixedly connected to the inner wall surface of the housing 10, and the second support portion 32 is fixedly connected to the side of the first support portion 31 away from the inner wall of the housing 10.

Optionally, when there are multiple busbars 20, the first support part 31 is also used to support some of the busbars 20, and the second support part 32 includes support columns 32a that correspond one-to-one with the remaining busbars 20, with the busbars 20 connected to the ends of the corresponding support columns 32a. Specifically, the busbars 20 supported by the support columns 32a of the second support part 32 can be grounding busbars 25.

Furthermore, the first bearing portion 31 is a U-shaped structural member composed of a first bent section 311, a second bent section 312, and a third bent section 313. The first bent section 311 and the third bent section 313 are respectively connected to the two opposite side edges of the second bent section 312, and the first bent section 311 and the third bent section 313 are arranged opposite to each other. The first bent section 311 is connected to the housing 10 by fasteners, and the third bent section 313 is connected to the second bearing portion 32 by fasteners.

With this configuration, the first bearing part 31 has a certain deformation capacity in two directions. Thus, when multiple busbar copper busbars 20 are subjected to stress from the second direction, the deformation of the first bearing part 31 can buffer the stress and disperse the stress between the busbar copper busbars 20 and the inner wall of the housing 10, thereby providing a certain protection for the multiple busbar copper busbars 20.

For example, the third bend section 313 of the first support portion 31 is provided with a connection hole, and the grounding bus 25 is fixedly connected to the connection hole by a metal fastener, so as to fix the grounding bus 25 to the third bend section 313. The first support portion 31 can be made of a conductive material, so as to electrically connect the grounding bus 25 to the housing 10, thereby realizing the leakage protection function of the grounding bus 25.

Furthermore, the second support portion 32 may include a connector and a plurality of support columns 32a. The connector is used to be fixedly connected to the first support portion 31. The plurality of support columns 32a are formed by the second support portion 32 protruding in a direction away from the inner wall of the housing 10, and the plurality of support columns 32a are spaced apart in the first direction.

In some specific examples, multiple support columns 32a are spaced apart in the first direction. The second bearing portion 32 includes a first support column, a second support column, a third support column, and a fourth support column, which are sequentially spaced apart in the first direction, and their dimensions decrease sequentially in the first direction. The end of the first support column is used to fix a first phase busbar 21 to a fastener; the end of the second support column is used to fix a second phase busbar 22 to a fastener; the end of the third support column is used to fix a third phase busbar 23 to a fastener; and the end of the fourth support column is used to fix a neutral busbar 24 to a fastener. The fasteners can be screws.

Optionally, as shown in Figure 6, there are multiple fixing seats 30, which are spaced apart on a third direction, and the third direction is perpendicular to the first direction and the second direction, respectively.

In this embodiment, the third direction can be the length direction of the power distribution device 1 (i.e., the left-right direction in the figure).

For example, a plurality of mounting bases 30 are arranged side by side and spaced apart along the length of the power distribution device 1. The first support columns of the plurality of mounting bases 30 are arranged side by side and spaced apart along the third direction to be used for a common fixed connection to the first phase bus 21. The second support columns of the plurality of mounting bases 30 are arranged side by side and spaced apart along the third direction to be used for a common fixed connection to the second phase bus 22. The third support columns of the plurality of mounting bases 30 are arranged side by side and spaced apart along the third direction to be used for a common fixed connection to the third phase bus 23. The fourth support columns of the plurality of mounting bases 30 are arranged side by side and spaced apart along the third direction to be used for a fixed connection to the neutral bus 24. The second bearing portions 32 of the plurality of mounting bases 30 are arranged side by side and spaced apart along the third direction to be used for a common fixed connection to the grounding bus 25.

Optionally, the first carrier part 31 may be made of a conductive material, and the second carrier part 32 may be made of an insulating material.

It should be noted that the specific material used for the second bearing part 32 in this embodiment is not limited. Those skilled in the art can make appropriate choices according to the actual situation. For example, it can be made of high-temperature resistant insulating materials such as ceramics, polytetrafluoroethylene (PTFE) or polyether ether ketone (PEEK).

This configuration can prevent short circuits between multiple busbars 20, thereby improving the reliability and safety of the power distribution device 1.

Figure 7 shows a schematic diagram of the relative positional relationship between the wiring module 40 and the plurality of busbars 20 in the power distribution device 1 of this application embodiment. As shown in Figure 7, optionally, the wiring module 40 and the plurality of busbars 20 are spaced apart in a second direction (i.e., the up-down direction in the figure).

For example, the wiring module 40 and the plurality of busbars 20 are spaced apart in the height direction of the power distribution device 1. Specifically, the wiring module 40 can be disposed below the plurality of busbars 20, and the wiring module 40 can be fixedly connected to the bottom wall of the housing 10 by fasteners. The plurality of busbars 20 are fixedly connected to the top wall of the housing 10 by a plurality of fixing seats 30 and are located above the wiring module 40. This arrangement enables electrical isolation between the plurality of busbars 20 and the wiring module 40.

In one embodiment, an isolation plate is provided between the wiring module 40 and the busbar copper bus 20.

For example, the isolation plate is made of a transparent and insulating material, such as a transparent acrylic sheet. The isolation plate is detachably installed in the receiving cavity and located between the wiring module 40 and the plurality of busbars 20.

This design serves two purposes: firstly, in the event of components such as screws falling from multiple busbar copper busbars 20, the isolation plate can act as a support, preventing the components from falling directly onto the wiring module 40 and causing a short circuit; secondly, during maintenance, it can physically isolate multiple busbar copper busbars 20, preventing maintenance personnel from touching the busbar copper busbars 20, thus providing safety protection.

In one embodiment, the second terminal of the wiring unit 41 is electrically connected to the ring terminal of the external cable via a conductive element.

For example, the second terminal of the wiring unit 41 is provided with a fastening hole that mates with the conductive element, for the conductive element to be inserted and fixedly connected. The end of the external cable is provided with an annular terminal, which is sleeved on the conductive element and pressed by the conductive element against the second terminal of the wiring unit 41, thereby realizing the fixation and electrical connection between the second terminal of the wiring unit 41 and the annular terminal of the external cable.

Through the above implementation method, on the one hand, the wiring difficulty between the wiring unit 41 and the external cable is reduced, and on the other hand, the tight fit between the ring terminal and the conductive component reduces the probability of the external cable and the wiring unit 41 becoming loose, improves the fixing effect of the external cable, and can also play a certain pulling role on the external cable to avoid the external cable exerting excessive pressure on the components below.

Figures 8 and 9 show schematic diagrams of the power distribution device 1 from different perspectives. As shown in Figures 8 and 9, in one embodiment, the power distribution device 1 further includes a plurality of connectors 50, which are correspondingly arranged with the wiring unit 41, and the connectors 50 have plug holes corresponding to the first wiring terminals of the wiring unit 41.

The connectors 50 are correspondingly provided with the second terminals of the wiring units 41, and the connectors 50 have through holes for the annular terminals of external cables to pass through, extend into the receiving cavity, and electrically connect to the second terminals of the corresponding wiring units 41.

In some alternative examples, connector 50 may be a waterproof connector to prevent moisture from entering the interior of the receiving cavity through connector 50, thereby improving the waterproof performance of power distribution device 1.

In some preferred embodiments, connector 50 may be a locking connector, and each cable outlet hole on housing 10 is provided with a locking connector for securing external cables passing through the cable outlet holes.

This improves the fixation of the external cable on the housing 10.

In one embodiment, as shown in Figures 8 and 9, the power distribution device 1 further includes at least one socket unit 60, each socket unit 60 being electrically connected to any one of the first phase bus 21, the second phase bus 22 and the third phase bus 23, the neutral bus 24 and the ground bus 25 respectively.

For example, the socket unit 60 is disposed on the bottom wall of the housing 10 and located outside the receiving cavity, for supplying power to the switch and other temporary load devices. The socket unit 60 can be electrically connected to the corresponding wiring unit 41 of the wiring module 40, and the corresponding wiring unit 41 can be electrically connected to one or all of the first phase bus 21, the second phase bus 22 and the third phase bus 23, the neutral bus 24 and the grounding bus 25 respectively.

Furthermore, the number and specifications of the socket units 60 can be specifically set by those skilled in the art according to actual conditions, and this application embodiment does not impose specific limitations on this. In terms of distance, the number of socket units 60 can be set to two, and the output current can be 10A.

In one embodiment, the power distribution device 1 may further include a fuse box, through which the socket unit 60 can be connected to the busbar 20 to prevent short circuits from affecting the busbar 20, thereby avoiding any impact on the power supply to the server module.

Figure 10 shows a bottom view of a power distribution device 1 according to an embodiment of the present application, Figure 11 shows a side view of a power distribution device 1 according to an embodiment of the present application, and Figure 12 shows a top view of a power distribution device 1 according to an embodiment of the present application.

The housing 10 defines a receiving cavity and an opening communicating with the receiving cavity. The cover plate 12 is rotatably connected to the housing 10 for opening and closing the opening.

For example, the opening is defined by the front side of the body 11, and the cover plate 12 includes a first part 121 and a second part 122 that are angled to each other and connected to each other. The lower edge of the first part 121 is connected to the upper edge of the second part 122, and the upper edge of the first part 121 is rotatably connected to the front side plate of the body 11 by a hinge. When the cover plate 12 is in the closed position, the two side edges of the left and right sides of the first part 121 overlap with the front edges of the left and right side plates of the body 11, respectively. The two side edges of the left and right sides of the second part 122 overlap with the lower edges of the left and right side plates of the body 11, respectively. The lower edge of the second part 122 overlaps with the front edge of the bottom plate of the body 11.

Furthermore, in this embodiment, the number of cover plates 12 can be one or more. For example, the number of cover plates 12 can be multiple, and the multiple cover plates 12 are arranged side by side and spaced apart in a third direction. Here, the third direction can be the length direction of the power distribution device 1.

According to the above embodiment, by providing a cover plate 12 that is rotatably connected to the main body 11, the opening can be closed and opened, and by opening the cover plate 12, it is convenient for staff to inspect and maintain the components in the cavity through the opening.

Optionally, a support rod is rotatably connected between the cover plate 12 and the body 11, and the end of the support rod is fixed to the body 11 when the cover plate 12 is in the open position.

For example, the first end of the support rod is rotatably connected to the inner wall of the housing 10, the cover plate 12 is provided with a sliding groove, and the end of the sliding groove is formed with a retaining groove, and the second end of the support rod is slidably disposed in the sliding groove. When the cover plate 12 is rotated to the open position, the second end of the support rod is engaged in the retaining groove to provide fixed support for the cover plate 12.

In one embodiment, as shown in Figures 8 and 9, the body 11 is provided with mounting lugs 111 on opposite sides in the third direction. The mounting lugs 111 are provided with mounting through holes 112 for fasteners to pass through.

For example, the main body 11 has mounting lugs 111 on opposite sides along the length of the power distribution device 1. Specifically, the mounting lugs 111 can be flat, and the plane containing the mounting lugs 111 is perpendicular to the first direction. The mounting lugs 111 are provided with mounting through holes 112 for fasteners to pass through and be fixedly connected to external devices. The fasteners can be screws, and the external devices can be walls or other devices, specifically the mounting surface of the power distribution device 1.

Through the above embodiments, the power distribution device 1 can be installed and fixed, and the connection reliability and stability of the power distribution device 1 can be improved by the two mounting lugs 111 arranged opposite to each other.

In one embodiment, as shown in Figures 1 and 2, the top wall of the housing 10 has a plurality of heat dissipation through holes 10a arranged in an array.

For example, the heat dissipation hole 10a penetrates the top wall of the housing 10 in the thickness direction of the top wall of the housing 10 to connect the receiving cavity with the external space, thereby dissipating the heat in the receiving cavity to the external space through the heat dissipation hole 10a, thereby achieving heat dissipation of the power distribution device 1.

In one embodiment, as shown in FIG8, the housing 10 has a cable through hole 11a on one of the two side walls that are arranged opposite each other in the third direction. The cable through hole 11a is used to allow the power supply cable to extend into the receiving cavity so that the power supply cable can be electrically connected to the bus copper bus 20.

For example, a cable through-hole 11a is provided on the left or right side wall of the housing 10. The cable through-hole 11a penetrates the left or right side wall of the housing 10 in the thickness direction to connect the receiving cavity with the external space, so that the terminal of the power supply cable can extend into the receiving cavity and be electrically connected to the multiple busbars 20. It should be noted that, in this embodiment, the shape of the cable through-hole 11a is not specifically limited, and those skilled in the art can set it according to the actual situation, for example, it can be set to be circular.

Optionally, a washer 13 is fitted around the edge of the cable through-hole 11a, and the washer 13 is made of a soft material.

For example, the washer 13 is embedded in the edge of the cable through hole 11a, and the washer 13 can be made of rubber or any other soft material.

The above-described implementation method can prevent the insulation sheath of the power supply cable from being damaged or even broken due to direct contact between the edge of the cable through hole 11a and the power supply cable, thereby protecting the power supply cable.

In one embodiment, the power distribution device 1 further includes an indicator light 14 disposed in the housing 10. The indicator light 14 is used to illuminate when the multiple busbar copper busbars 20 are powered on. The indicator light 14 may be disposed on the outer surface of the cover plate 12.

This configuration allows the indicator light 14 to alert maintenance personnel or staff that the power distribution device 1 is powered on when the upstream power supply equipment (such as the distribution cabinet) is switched on, thereby reducing the probability of accidents and improving the safety performance of the power distribution device 1.

In addition, a branch switch is provided at the first terminal of the wiring unit 41 to connect or disconnect the electrical connection between the busbar copper busbars 20 and the wiring unit 41. Both the main switch and the branch switch can be appropriate types of circuit breakers.

Through the above implementation method, the power supply to multiple busbar copper busbars 20 and the power supply to each wiring unit 41 are controlled, so that the corresponding circuit can be flexibly disconnected or connected according to the needs, which facilitates the maintenance of the power distribution device 1 by the staff.

Optionally, the power distribution device 1 further includes a control module and a communication module. The control module communicates electrically with the main switch and/or branch switches via the communication module, and is used to control the opening and closing of the main switch and/or branch switches. Furthermore, in other examples of this application, the main switch and/or branch switches can also be operated manually.

In this embodiment, the communication module is also used to communicate electrically with an external terminal device and to receive control signals sent by the external terminal device to the main switch or the branch switch; in response to the control signals, the control module controls the opening and closing of the main switch and/or the branch switch, thereby realizing remote control of the power distribution device 1.
