In one embodiment, the plurality of bus bars 20 may include one or all of a first phase bus bar 21, a second phase bus bar 22, a third phase bus bar 23, and a neutral bus bar 24 and a ground bus bar 25.
In some examples, the plurality of bus bars 20 includes a first phase bus bar 21, a second phase bus bar 22, a third phase bus bar 23, a neutral bus bar 24, and a ground bus bar 25. The power distribution apparatus 1 according to the embodiment of the present application may employ a three-phase five-wire ac mode. Specifically, among the plurality of bus bar copper bars 20, three bus bar copper bars 20 may be electrically connected with three-phase power lines (L1, L2, L3) to form a first phase bus bar 21, a second phase bus bar 22, and a third phase bus bar 23, respectively, one bus bar copper bar 20 may be electrically connected with a neutral line (N) to form a neutral bus bar 24, and another bus bar copper bar 20 may be electrically connected with a ground line (P) to form a ground bus bar 25. Thereby, three-phase power supply of the power distribution apparatus 1 can be achieved.
Furthermore, in other examples, the power distribution apparatus 1 may also be used for single-phase power supply. For example, among the plurality of bus bars 20, any one of the first phase bus bar 21, the second phase bus bar 22, and the third phase bus bar 23 may constitute a single-phase power supply with a neutral line and a ground line.
In one embodiment, the number of the bus bar copper bars 20 is plural, each bus bar 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 terminal of each wiring unit 41 is electrically connected with one end of a plurality of inner wiring cables through fasteners, and the other end of the plurality of inner wiring cables is electrically connected with at least part of the bus bar copper bars 20 through fasteners penetrating through the first wiring holes.

Illustratively, the plurality of wiring units 41 include a first wiring unit having an input terminal electrically connected to any one of the first phase bus bar 21, the second phase bus bar 22, and the third phase bus bar 23, the neutral bus bar 24, and the ground bus bar 25, and a second wiring unit electrically connected to the first phase bus bar 21, the second phase bus bar 22, the third phase bus bar 23, the neutral bus bar 24, and the ground bus bar 25, respectively.
In addition, the electrical connection between the one end of the inner cable and the first end of the wiring unit 41 may be achieved by a plugging manner or a fastening manner, which is not particularly limited in the present application.
Optionally, the second terminal of each wiring unit 41 is electrically connected to one end of an external cable through a fastener, and the other end of the external cable is electrically connected to the electrical device.
The fastening member may be a metal screw, and one end of the external cable is electrically connected to the second terminal through the metal screw, and the other end of the external cable extends out of the housing 10 and is electrically connected to the electric device.
Optionally, the housing 10 is further provided with at least one outlet through hole communicating the accommodating cavity with the outside, and the other end of the external connection cable extends to the outside of the accommodating cavity through the corresponding outlet through hole.
Illustratively, the plurality of wiring units 41 are arranged side by side in the third direction. In the embodiment of the present application, the third direction may be a direction perpendicular to the first direction and the second direction, and specifically may be a length direction of the power distribution apparatus 1. The plurality of outlet through holes are provided in one-to-one correspondence with the plurality of wiring units 41 so that the external cables connected to the second terminals of the wiring units 41 can be extended to the outside of the housing 10 through the corresponding outlet through holes.
In some alternative examples of the present application, the other ends of the plurality of external connection cables may commonly protrude to the outside of the accommodating chamber through one outlet through hole. By the arrangement, the number of the outlet through holes on the shell 10 can be reduced, and the processing difficulty of the shell 10 is reduced.
Alternatively, as shown in fig. 3, the ratio of the pitch of two adjacent bus bar copper bars 20 in the first direction to the dimension of the bus bar copper bars 20 in the first direction is 1 to 2.
In the embodiment of the present application, the first direction may be the width direction of the power distribution device 1 (i.e., the front-rear direction in the drawing), the width direction of the bus bar 20 is parallel to the width direction of the power distribution device 1, and the dimension of the bus bar 20 in the first direction may be understood as the width dimension of the bus bar 20.
Illustratively, the ratio between the pitch of adjacent two bus bar copper bars 20 in the first direction and the width dimension of the bus bar copper bars 20 may be 1 to 2. Preferably, the ratio between the pitch of the adjacent two bus bar copper bars 20 in the first direction and the width dimension of the bus bar copper bars 20 may be 1.5.
In some specific examples, the width dimension of the busbar 20 may be 30mm, and the pitch of two adjacent busbar 20 in the first direction may be 45mm.
It should be noted that, when the interval between two adjacent bus bar copper bars 20 in the first direction is too large, for example, the ratio of the size of the bus bar copper bars 20 in the first direction is greater than 2, the plurality of bus bar copper bars 20 occupy too much space in the first direction, so that the width of the power distribution device 1 occupies too much installation space; in the case where the pitch between the adjacent two bus bar copper bars 20 in the first direction is too small, for example, the ratio to the dimension of the bus bar copper bars 20 in the first direction is smaller than 1, the wiring space between the adjacent two bus bar copper bars 20 is too small, thereby causing inconvenience to the wiring between the bus bar copper bars 20 and the wiring module 40.
Therefore, by setting the ratio of the pitch of the adjacent two bus bar copper bars 20 in the first direction to the size of the bus bar copper bars 20 in the first direction to 1 to 2, it is not only advantageous to reduce the external dimension of the power distribution device 1, thereby reducing the occupation of the installation space, but also possible to bring convenience to the wiring between the bus bar copper bars 20 and the wiring module 40.
Alternatively, the ratio of the pitch of the adjacent two bus bar copper bars 20 in the second direction to the dimension of the bus bar copper bars 20 in the second direction is 3 to 7.
In the embodiment of the present application, the second direction may be a height direction (i.e., an up-down direction in the illustrated example) of the power distribution device 1, the thickness direction of the bus bar copper 20 is parallel to the height direction of the power distribution device 1, and the dimension of the bus bar copper 20 in the second direction may be a thickness dimension of the bus bar copper 20.
Illustratively, the ratio between the pitch of the adjacent two bus bar copper bars 20 in the second direction and the height dimension of the bus bar copper bars 20 may be 3 to 7. Preferably, the ratio between the pitch of the adjacent two bus bar copper bars 20 in the second direction and the height dimension of the bus bar copper bars 20 may be 5.
In some specific examples, the thickness dimension of the busbar 20 may be 5mm, and the pitch of two adjacent busbar 20 in the second direction may be 25mm.
It should be noted that, when the interval between two adjacent bus bar copper bars 20 in the second direction is too large, for example, the ratio of the dimension of the bus bar copper bars 20 in the second direction is greater than 7, the plurality of bus bar copper bars 20 occupy too much space in the second direction, so that the power distribution device 1 occupies too much installation space due to the too large height dimension; in the case where the pitch between the adjacent two bus bar copper bars 20 in the second direction is too small, for example, the ratio of the size of the bus bar copper bars 20 in the second direction is less than 3, the wiring space between the adjacent two bus bar copper bars 20 is too small, thereby causing inconvenience to the wiring between the bus bar copper bars 20 and the wiring module 40.
Therefore, by setting the ratio of the pitch of the adjacent two bus bar copper bars 20 in the second direction to the size of the bus bar copper bars 20 in the second direction to 3 to 7, it is not only advantageous to reduce the external dimension of the power distribution device 1, thereby reducing the occupation of the installation space, but also possible to bring convenience to the wiring between the bus bar copper bars 20 and the wiring module 40.
In one embodiment, the busbar 20 is further provided with a second wire aperture for electrical connection with a distribution cable of the distribution device by means of a fastener.
