The power distributor 100 may be applied to a data center such as a mobile data center (not shown in the figure). In the following description of the present application, the application of the power distributor 100 in a data center, such as a mobile data center, is taken as an example for description.
如图1-图10所示，根据本发明第一方面实施例的电源分配器100，包括接线端子1、至少三个插座2和至少三个熔断器3。As shown in FIG. 1 to FIG. 10, the power distributor 100 according to the embodiment of the first aspect of the present invention includes a connection terminal 1, at least three sockets 2 and at least three fuses 3.
具体而言，接线端子1包括第一火线端子11、第二火线端子12、第三火线端子13和零线端子14，每个插座2上形成有第一插孔21和第二插孔22，第一插孔21内具有第一金属触头211，第二插孔22内具有第二金属触头221，所有插座2的第一金属触头211均与零线端子14相连。至少三个熔断器3中的其中一个熔断器3的一端(例如，图7中的左端)与第一火线端子11相连、且另一端(例如，图7中的右端)与至少一个插座2的第二金属触头221相连，至少三个熔断器3中的另一个熔断器3的一端(例如，图7中的左端)与第二火线端子12相连、且另一端(例如，图7中的右端)与另至少一个插座2的第二金属触头221相连，至少三个熔断器3中的再一个熔断器3的一端(例如，图7中的左端)与第三火线端子13相连、且另一端(例如，图7中的右端) 与再至少一个插座2的第二金属触头221相连，每个熔断器3的分断能力为σ，其中σ满足：σ≥50kA。这里，需要说明的是，“另至少一个插座2”可以理解为除与上述其中一个熔断器3相连的至少一个插座2之外其余的至少一个插座2，类似地，“再至少一个插座2”可以理解为除与上述其中一个熔断器3、另一个熔断器3相连的插座2之外其余的至少一个插座2。Specifically, the connection terminal 1 includes a first live terminal 11, a second live terminal 12, a third live terminal 13 and a neutral terminal 14. Each socket 2 is formed with a first socket 21 and a second socket 22, The first socket 21 has a first metal contact 211 and the second socket 22 has a second metal contact 221. The first metal contacts 211 of all sockets 2 are connected to the neutral terminal 14. One end of one of the at least three fuses 3 (for example, the left end in FIG. 7) is connected to the first live terminal 11, and the other end (for example, the right end in FIG. 7) is connected to at least one socket 2 The second metal contact 221 is connected, one end of the other fuse 3 of the at least three fuses 3 (for example, the left end in FIG. 7) is connected to the second live wire terminal 12, and the other end (for example, the The right end) is connected to the second metal contact 221 of at least one other socket 2, and one end (for example, the left end in FIG. 7) of another fuse 3 of the at least three fuses 3 is connected to the third live wire terminal 13, and The other end (for example, the right end in FIG. 7) is connected to at least one second metal contact 221 of the socket 2, and the breaking capacity of each fuse 3 is σ, where σ satisfies: σ≥50kA. Here, it should be noted that "the other at least one socket 2" can be understood as at least one socket 2 other than the at least one socket 2 connected to one of the above-mentioned fuses 3, similarly, "the other at least one socket 2" It can be understood as at least one socket 2 other than the socket 2 connected to one of the fuse 3 and the other fuse 3 mentioned above.
例如，在图1-图4和图7的示例中示出了十三个插座2和六个熔断器3，其中，左侧的两个熔断器3的左端均与第三火线端子13相连，且左侧两个熔断器3中的每个熔断器3的右端分别与最左侧的四个插座2的第二金属触头221相连，中间的两个熔断器3的左端均与第二火线端子12相连，且中间两个熔断器3中的每个熔断器3的右端分别与中间的四个插座2的第二金属触头221相连，右侧的两个熔断器3的左端均与第一火线端子11相连，且右侧两个熔断器3中的其中一个的右端与靠右的两个插座2的第二金属触头221相连、另一个与最右侧的三个插座2的第二金属触头221相连，每个插座2的第一金属触头211均与零线端子14相连。由于每个熔断器3的分断能力σ≥50kA，熔断器3的分断能力较强，电源分配器100可以应用在移动数据中心内，使电源分配器100在邻近变压器一侧可以保证负载的安全。For example, in the examples of FIGS. 1 to 4 and 7 there are shown thirteen sockets 2 and six fuses 3, wherein the left ends of the two fuses 3 on the left are both connected to the third live wire terminal 13, And the right end of each of the two fuses 3 on the left is connected to the second metal contacts 221 of the four sockets 2 on the far left, and the left ends of the two fuses 3 in the middle are both connected to the second live wire. The terminals 12 are connected, and the right end of each of the two fuses 3 in the middle is connected to the second metal contacts 221 of the four sockets 2 in the middle, and the left ends of the two fuses 3 on the right are connected to the first A live wire terminal 11 is connected, and the right end of one of the two fuses 3 on the right is connected with the second metal contacts 221 of the two sockets 2 to the right, and the other is connected with the first metal contacts of the three sockets 2 on the far right. The two metal contacts 221 are connected, and the first metal contact 211 of each socket 2 is connected to the neutral terminal 14. Since the breaking capacity of each fuse 3 is σ≥50kA, and the breaking capacity of the fuse 3 is relatively strong, the power distributor 100 can be applied in a mobile data center, so that the power distributor 100 can ensure the safety of the load on the side adjacent to the transformer.
图1-图4和图7中显示了十三个插座2和六个熔断器3用于示例说明的目的，但是普通技术人员在阅读了本申请的技术方案之后、显然可以理解将该方案应用到其它数量的插座2和熔断器3的技术方案中，这也落入本发明的保护范围之内。Figures 1 to 4 and Figure 7 show thirteen sockets 2 and six fuses 3 for illustrative purposes, but after reading the technical solution of this application, a person of ordinary skill can obviously understand the application of this solution In the technical solutions of other numbers of sockets 2 and fuses 3, this also falls within the protection scope of the present invention.

Therefore, each fuse 3 can protect two or three sockets 2 correspondingly, thereby ensuring the safety of the load connected to the socket 2.
在本发明的一些实施例中，如图1、图2和图7所示，每个插座2上还形成有第三插孔23，第三插孔23内具有第三金属触头231，所有插座2的第三金属触头231与接地端子15相连。由此，当接入插座2的负载漏电时，漏电电流可以被导入大地，从而保证了人员以及负载的安全。In some embodiments of the present invention, as shown in FIG. 1, FIG. 2 and FIG. 7, each socket 2 is further formed with a third socket 23, and the third socket 23 has a third metal contact 231.
