DETAILED DESCRIPTION

Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

The power distribution device 1 according to an embodiment of the present application is described below with reference to FIG. 1 to FIG. 12 .

FIG1 shows a schematic structural diagram of a power distribution device 1 according to an embodiment of the present application, and FIG2 shows an exploded structural diagram of the power distribution device 1 according to an embodiment of the present application. As shown in FIG1 and FIG2 , the power distribution device 1 includes a housing 10, a busbar 20, and a wiring module 40. Specifically, the interior of the housing 10 defines a housing cavity. The busbar 20 is disposed in the housing cavity, and the busbar 20 is electrically connected to the power supply cable of the power distribution equipment. The wiring module 40 is disposed in the housing cavity, and the wiring module 40 is electrically connected to the busbar 20 via an internal cable, and is electrically connected to the electrical equipment via an external cable.

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

In the embodiment of the present application, the number of busbar copper bars 20 can be one or more. FIG3 shows a schematic structural diagram of multiple busbar copper bars 20 of the power distribution device 1 according to the embodiment of the present application. As shown in FIG3 , in some optional examples of the present application, the number of busbar copper bars 20 can be multiple, and the multiple busbar copper bars 20 are spaced apart in the first direction.

For example, the busbar copper bar 20 can be made of 99.9% pure electrolytic copper. The size of the busbar copper bar 20 can be set according to the total current carrying capacity of all wiring units 41 included in the wiring module 40. The larger the total current carrying capacity, the larger the size of the busbar copper bar 20. Those skilled in the art can flexibly set the size of the busbar copper bar 20 according to actual needs, and this embodiment of the present application does not specifically limit this.

In the embodiment of the present application, the wiring module 40 is spaced apart from the busbar 20 within the accommodating cavity. The wiring module 40 may include multiple wiring units 41, each of which has a first terminal and a second terminal. The first terminal is used to electrically connect to the busbar 20 via an internal cable, and the second terminal is used to electrically connect to an electrical device via an external cable. This achieves electrical connection between the busbar 20 and the electrical device, thereby providing power to the electrical device.

According to the power distribution device 1 of the embodiment of the present application, by adopting the busbar copper bus 20 as the busbar, on the one hand, 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, and the material of the busbar copper bus 20 can be reused, thereby reducing depreciation costs.

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

It should be noted that the first direction can be any direction, for example, the vertical direction or the horizontal direction after the power distribution device 1 is installed. That is, the multiple busbars 20 can be spaced apart from each other in the vertical direction or in the horizontal direction.

By spacing the multiple busbar copper bars 20 in the first direction, it is possible to ensure that there is sufficient electrical clearance between the multiple busbar copper bars 20, so that when wiring the multiple busbar copper bars 20 and the wiring module 40, sufficient wiring space can be reserved for multiple internal cables. On the one hand, the convenience of wiring is improved, and on the other hand, the probability of internal cables contacting other busbar copper bars 20 can be reduced, thereby improving the working reliability of the power distribution device 1.

Figure 4 shows a schematic structural diagram of multiple busbars 20 of the power distribution device 1 of an embodiment of the present application. As shown in Figure 4, in one embodiment, the multiple busbars 20 are spaced apart in the second direction, and the second direction is perpendicular to the first direction.

In the embodiment of the present application, the first direction may be any direction, and the second direction may be another direction perpendicular to the first direction.

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

More specifically, the busbar copper busbar 20 can be in the form of a flat plate, and the plane on which each busbar copper busbar 20 is located can be perpendicular to the second direction. For example, the second direction can be a vertical direction, and the planes on which the multiple busbar copper busbars 20 are located can be perpendicular to the vertical direction, that is, the planes on which the multiple busbar copper busbars 20 are located can be parallel to the horizontal plane.

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

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

In some other examples, the power distribution device 1 can also be used for single-phase power supply. For example, among the multiple busbars 20, any one of the first phase busbar 21, the second phase busbar 22, and the third phase busbar 23, together with the neutral line and the ground line, can form a single-phase power supply.

In one embodiment, there are multiple busbar copper bars 20, each busbar copper bar 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 end of each wiring unit 41 is electrically connected to one end of several internal cables through a fastener, and the other ends of the several internal cables are respectively electrically connected to at least part of the busbar copper bars 20 through fasteners passing through the first wiring holes.

Optionally, the multiple busbar copper bars 20 include a neutral busbar 24 and a grounding busbar 25, and also include one or all of the first phase busbar 21, the second phase busbar 22, and the third phase busbar 23; the first connection terminal of each wiring unit 41 is electrically connected to one end of the multiple internal cables through a fastener, and the other ends of the multiple internal cables are respectively electrically connected to the first connection holes of the first phase busbar 21, the second phase busbar 22, and the third phase busbar 23, the neutral busbar 24, and the grounding busbar 25 through fasteners.

Exemplarily, the multiple wiring units 41 include a first wiring unit and a second wiring unit, the input end of the first wiring unit is electrically connected to the first phase bus 21, any one of the second phase bus 22 and the third phase bus 23, the neutral bus 24 and the ground bus 25, respectively, and 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 and the first end of the wiring unit 41 can also be electrically connected by plugging or snapping, which is not specifically limited in this application.

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 an electrical device.

Exemplarily, 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 from the housing 10 and is electrically connected to the electrical device.

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

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

In some optional examples of the present application, the other ends of multiple external cables can be extended to the outside of the accommodating cavity through a common outlet hole. This arrangement can reduce the number of outlet holes on the housing 10 and reduce the difficulty of processing the housing 10.

Optionally, as shown in FIG3 , the ratio of the distance between two adjacent busbar copper bars 20 in the first direction to the size of the busbar copper bar 20 in the first direction is 1 to 2.

In an embodiment of the present application, 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 arranged parallel to the width direction of the power distribution device 1. The size of the busbar copper bus 20 in the first direction can be understood as the width size of the busbar copper bus 20.

For example, the ratio of the distance between two adjacent busbar copper bars 20 in the first direction to the width of the busbar copper bar 20 may be 1 to 2. Preferably, the ratio of the distance between two adjacent busbar copper bars 20 in the first direction to the width of the busbar copper bar 20 may be 1.5.

In some specific examples, the width of the busbar copper bar 20 may be 30 mm, and the distance between two adjacent busbar copper bars 20 in the first direction may be 45 mm.

It should be noted that, when the distance between two adjacent busbar copper bars 20 in the first direction is too large, for example, when the ratio of the distance between the busbar copper bars 20 and the size of the busbar copper bars 20 in the first direction is greater than 2, it will cause multiple busbar copper bars 20 to occupy too much space in the first direction, thereby causing the width of the power distribution device 1 to be too large and occupy too much installation space; when the distance between two adjacent busbar copper bars 20 in the first direction is too small, for example, when the ratio of the distance between the busbar copper bars 20 and the size of the busbar copper bars 20 in the first direction is less than 1, it will cause the wiring space between the two adjacent busbar copper bars 20 to be too small, thereby causing inconvenience to the wiring between the busbar copper bars 20 and the wiring module 40.

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

Optionally, the ratio of the distance between two adjacent busbar copper bars 20 in the second direction to the size of the busbar copper bar 20 in the second direction is 3 to 7.

In an embodiment of the present application, 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 busbar copper bus 20 is arranged parallel to the height direction of the power distribution device 1, and the size of the busbar copper bus 20 in the second direction can be the thickness size of the busbar copper bus 20.

For example, the ratio of the distance between two adjacent busbar copper bars 20 in the second direction to the height of the busbar copper bar 20 may be 3 to 7. Preferably, the ratio of the distance between two adjacent busbar copper bars 20 in the second direction to the height of the busbar copper bar 20 may be 5.

In some specific examples, the thickness of the busbar copper bar 20 may be 5 mm, and the distance between two adjacent busbar copper bars 20 in the second direction may be 25 mm.

It should be noted that, when the distance between two adjacent busbar copper bars 20 in the second direction is too large, for example, when the ratio of the distance between the busbar copper bars 20 and the size of the busbar copper bars 20 in the second direction is greater than 7, it will cause multiple busbar copper bars 20 to occupy too much space in the second direction, thereby causing the height dimension of the power distribution device 1 to be too large and occupy too much installation space; when the distance between two adjacent busbar copper bars 20 in the second direction is too small, for example, when the ratio of the distance between the busbar copper bars 20 and the size of the busbar copper bars 20 in the second direction is less than 3, it will cause the wiring space between the two adjacent busbar copper bars 20 to be too small, thereby causing inconvenience to the wiring between the busbar copper bars 20 and the wiring module 40.

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

In one embodiment, the busbar copper bar 20 is further provided with a second wiring hole for electrically connecting to the distribution cable of the power distribution equipment through a fastener.

For example, the second wiring hole can be provided adjacent to the edge of the busbar copper bar 20 to reduce the length of the distribution cable extending into the accommodating cavity and improve the convenience of wiring.

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

Exemplarily, the fixing seat 30 includes a plurality of support columns 32 a corresponding to the plurality of busbar copper bars 20 , and the busbar copper bars 20 are connected to ends of the corresponding support columns 32 a , wherein the lengths of the plurality of support columns 32 a in the second direction are different.

Optionally, the fixing seat 30 includes a first bearing portion 31 and a second bearing portion 32 , the first bearing portion 31 is connected to the housing 10 , the second bearing portion 32 is connected to the first bearing portion 31 , and the second bearing portion 32 is used to bear the busbar 20 .

Exemplarily, the fixing base 30 is disposed in the accommodating cavity and is fixedly connected to the housing 10 by fasteners. The fixing base 30 may include a first bearing portion 31 and a second bearing portion 32, wherein the first bearing portion 31 is fixedly connected to the inner wall surface of the housing 10, and the second bearing portion 32 is fixedly connected to a side of the first bearing portion 31 away from the inner wall of the housing 10.

Optionally, when there are multiple busbars 20, the first supporting portion 31 is also used to support some of the busbars 20, and the second supporting portion 32 includes support columns 32a provided in a one-to-one correspondence with the remaining busbars 20, and the busbars 20 are connected to the ends of the corresponding support columns 32a. The busbars 20 supported by the support columns 32a of the second supporting portion 32 can specifically be grounding busbars 25.

Furthermore, the first bearing portion 31 is a U-shaped structural member composed of a first bending section 311, a second bending section 312 and a third bending section 313, the first bending section 311 and the third bending section 313 are respectively connected to the two opposite side edges of the second bending section 312, and the first bending section 311 and the third bending section 313 are arranged opposite to each other, wherein the first bending section 311 is connected to the shell 10 through a fastener, and the third bending section 313 is connected to the second bearing portion 32 through a fastener.

With such a configuration, the first bearing portion 31 has a certain deformation capacity in two directions. Therefore, when the multiple busbar copper bars 20 are subjected to stress from the second direction, the stress can be buffered by the deformation of the first bearing portion 31, and the stress between the busbar copper bar 20 and the inner wall of the shell 10 can be dispersed, thereby providing a certain protection for the multiple busbar copper bars 20.

For example, the third bent section 313 of the first supporting portion 31 is provided with a connection hole, and the grounding busbar 25 is fixedly connected to the connection hole via a metal fastener, thereby fixing the grounding busbar 25 to the third bent section 313. The first supporting portion 31 can be made of a conductive material to electrically connect the grounding busbar 25 to the housing 10, thereby realizing the leakage protection function of the grounding busbar 25.

Furthermore, the second bearing part 32 may include a connecting member and multiple support columns 32a, the connecting member is used to be fixedly connected to the first bearing part 31, the multiple support columns 32a are formed by the second bearing part 32 protruding in a direction away from the inner wall of the shell 10, and the multiple support columns 32a are arranged at intervals in the first direction.
