[0030] Figure 1 and Figure 2 The distribution cabinet 10 of the present utility model is shown by way of example. Figure 3 and Figure 4 The complete power distribution equipment 100 including the distribution cabinet 10 of the present utility model is shown by way of example. In this example, the distribution cabinet 10 can avoid increasing the overall size of the distribution cabinet 10 while arranging multiple groups of main busbars, and is convenient for users to operate and maintain the distribution cabinet 10.

[0031] As Figure 1 and Figure 2 shown, the distribution cabinet 10 may include a cabinet body 11, at least two groups of main busbars and one or more functional units such as a circuit breaker. For the convenience of description and illustration, the horizontal direction described herein may be regarded as Figure 2 the in-out direction of the page where it is located, i.e., the front-back direction, the longitudinal direction may be regarded as Figure 2 the left-right direction of the page where it is located, and the vertical direction may be regarded as Figure 2 the up-down direction of the page where it is located.

[0032] The cabinet body 11 may include a main frame 111, multiple side plates installed on the peripheral side of the main frame 111 to cooperate with the main frame 111 to form the cabinet body 11, and multiple partition plates installed inside the main frame 111 to divide the inside of the cabinet body 11 into multiple compartments. It can be understood that, for the convenience of showing the structural components inside the distribution cabinet 10, Figure 1 and Figure 2The left and right side plates of the power distribution cabinet 10 are removed, and only the front side plate 121, the rear side plate 122, the upper side plate 123, and the lower side plate 124 are shown.

[0033] The multiple compartments inside the cabinet body 11 may include a busbar compartment 131, a functional compartment 132, a cable compartment 133, and a secondary component compartment 134. The busbar compartment 131 extends vertically inside the cabinet body 11 and is generally centered vertically within the cabinet body 11. Since the vertical dimension of the cabinet body 11 is larger compared to the horizontal and longitudinal dimensions, the space of the busbar compartment 131 is larger than that of the busbar compartment 131 located at the top of the cabinet body 11 in the prior art. Furthermore, multiple groups of main busbars can be arranged vertically at intervals within the busbar compartment 131, preferably more than three groups of main busbars.

[0034] The functional unit compartment is located on the front side of the busbar compartment 131 and is generally arranged opposite to the busbar compartment 131 longitudinally, so as to facilitate the user to connect the main busbars in the busbar compartment 131 to the functional units in the functional compartment 132. The cable compartment 133 also extends vertically inside the cabinet body 11 and is generally centered vertically within the cabinet body 11. The cable compartment 133 is also located on the other side of the busbar compartment 131 relative to the functional compartment 132, that is, located on the rear side of the busbar compartment 131 and generally arranged opposite to the busbar compartment 131 longitudinally, so as to facilitate the user to connect external cables within the cable compartment 133, and the external cables can enter and exit vertically within the cable compartment 133. The secondary component compartment 134 is arranged on the upper side of the functional compartment 132 and is also located on the front side of the busbar compartment 131 together with the functional compartment 132, so as to facilitate the user to arrange various auxiliary components within the secondary component compartment 134, such as auxiliary components for controlling, monitoring, measuring, or tracking the primary circuit.

[0035] Specifically, the multiple compartments inside the cabinet body 11 can be separated by multiple columns and longitudinal beams installed within the main frame 111, and partition plates with a shape adapted thereto can be installed on the columns and longitudinal beams to form the respective required compartments. As Figure 2 shown, the functional compartment 132 can be regarded as being defined by the first column 141 extending vertically, the front side portion of the main frame 111, and the first longitudinal beam 143 and the second longitudinal beam 144 extending horizontally. The secondary component compartment 134 can be regarded as being defined by the first column 141, the first longitudinal beam 143, the front side portion and the top side portion of the main frame 111. The busbar compartment 131 can be regarded as being defined by the second column 142 extending vertically, the first column 141, the third longitudinal beam 145 extending horizontally, and the second longitudinal beam 144. The cable compartment 133 can be defined by the second column 142, the rear side portion of the main frame 111, and the fourth longitudinal beam 146 and the second longitudinal beam 144 extending horizontally.

[0036] Understandably, the multiple compartments of the distribution cabinet 10 provided by the present utility model satisfy the mutual relationship between any two of the above, and the specific size limits of each compartment can be selected according to actual needs.

[0037] Among them, at least two groups of main busbars can be provided in the busbar compartment 131, and each group of main busbars can be connected to an external power source or an external load. One or more functional units can be provided in the functional compartment 132, and the functional unit can be connected to one group or multiple groups of main busbars among all the main busbars.

The main busbar C 153 can extend out of the cabinet body 11 of the distribution cabinet 10 along the horizontal direction towards the Figure 4 shown right side and enter the cabinet body 11 of the additional distribution cabinet 20 to be connected to the load 21 in the additional distribution cabinet 20.

[0040] Optionally, each group of main busbars extending in the distribution cabinet 10 and the additional distribution cabinet 20 can be composed of segmented main busbars respectively located in the distribution cabinet 10 and the additional distribution cabinet 20, and the corresponding segmented main busbars extend along the same horizontal direction and are connected via fasteners. For example, they are connected at the junction of the distribution cabinet 10 and the additional distribution cabinet 20.

[0041] In the functional compartment 132 of the power distribution cabinet 10, two functional units may be provided. For the convenience of clear illustration, the two functional units may be respectively labeled as functional unit A 161 and functional unit B 162 from top to bottom.

In an embodiment not shown, multiple sets of main busbars in the busbar compartment 131 may be respectively connected to different external loads. In an embodiment not shown, the power distribution cabinet 10 and the additional power distribution cabinet 20 in the complete power distribution equipment 100 may be constructed in the same manner.

[0043] In short, the power distribution cabinet 10 and the complete power distribution equipment 100 provided by the present utility model can provide users with flexible and variable power supply solutions, especially customized power supply solutions according to user needs.

[0044] Optionally, as shown in Figure 1 and Figure 2 , each set of main busbars includes a positive busbar and a negative busbar, both the positive busbar and the negative busbar extend horizontally and are spaced apart from each other longitudinally. Thus, one of the positive busbar and the negative busbar may face the functional compartment 132, and the other may face the cable compartment 133, which is convenient for users to operate and maintain.
