A plurality of plug-in boxes 3 are arranged on the back of the lower case 2. The plug-in boxes 3 are plugged on the copper bars of the busbar system 200. The plug-in boxes 3 are connected to a circuit breaker 4. A monitoring board modular structure 5 is arranged on one side of the circuit breaker 4, and the number of the monitoring board modular structures 5 is the same as the number of the plug-in boxes 3 correspondingly. A plurality of connectors 6 are arranged on the upper case 1 for externally connecting communication cables. A control panel 41 is arranged on the circuit breaker 4, which protrudes out of the outer surface of the upper case 1 and is exposed. And the circuit breaker 4 described in the embodiment of the present application adopts a 3P air switch.

[0048] In this embodiment, the upper case 1 includes a main panel 11 in the upper part and an auxiliary panel 12 in the lower part.

During the wiring process, first fix the two lower screws on the auxiliary panel 12. After the wiring is completed, the main panel can be directly installed, and the installation screws on the main panel are supplemented. This structure ensures the orderliness of the wiring and ensures the shortest wiring, saving costs.

[0049] Furthermore, in this embodiment, as Figure 4 and 5 shown, the box body 100 further includes a fixing member 7. Specifically, it is a fixing sheet metal. The fixing member 7 is arranged in a U-shaped structure. Its upper end is connected to the circuit breaker 4, and its lower end straddles both sides of the plug-in box 3.

[0050] Furthermore, in this embodiment, as Figure 6 and 7 shown, the plug-in box 3 includes a main board 31, a card slot assembly 32 arranged on the main board 31, and plug-in slots 33 arranged at the upper and lower ends of the main board 31. The plug-in slots 33 are used for installing corresponding signal elastic pieces. The card slot assembly 32 includes a plurality of groups of card slots 321. A first through hole 34 is arranged on the main board 31 corresponding to each group of card slots 321. The power-taking reed piece passes through the first through hole 34 and is placed in the corresponding card slot 321. The plug-in slots 33 and the card slots 321 are on the same side of the main board 31. A wiring slot 323 corresponding to the card slot 321 is arranged on the other side of the main board 31, and each wiring slot 323 has a corresponding first through hole 34. A connecting piece 8 is arranged on the wiring slot 323 to connect the power-taking reed piece to the 3P air switch. The shape and position of the connecting piece 8 are set according to the positions of the plug-in box and the circuit breaker according to the shortest route, and finally power-taking on demand is completed.

[0051] In this embodiment, several power-taking springs are required to be set in the corresponding first through holes 34, which is set according to the power required by the customer. In one embodiment of the present application, the card slots 321 are set to 5 groups, and each group of card slots 321 is provided with power-taking springs for taking power.

[0053] In this embodiment, if Figure 8 As shown, the monitoring board modular structure 5 includes a communication fixing board 51 , on which a substrate 511 and modular components are arranged. The modular components include a board 512 , and the substrate 511 and the board 512 are communicatively connected via a gold finger 513 .

[0054] The modular component also includes a mounting plate 514, a panel 517 and an upper cover 515. The mounting plate 514 and the panel 515 are vertically arranged. The mounting plate 514 and the upper cover 515 are installed correspondingly to form a accommodating space. The panel 517 covers the side of the accommodating space, and the board 512 is arranged on the inner wall of the mounting plate 514.

[0055] In this embodiment, Fig. 9 As shown, the modular component also includes a guide rail 516. A convex strip 5141 is provided on the outer end surface of the mounting plate 514 away from the upper cover 515. The upper and lower ends thereof are provided with guide rails 516. The guide rails 516 are arranged across the convex strips 5141. When the board needs to be replaced, the panel is directly pulled outward, and the modular component slides and disengages directly under the action of the guide rail 516. After the replacement is completed, the convex strip 5141 is directly stuck on the guide rail 516 and pushed inward. In this embodiment, the positional relationship between the modular component and the guide rail 516 is specifically limited, as long as sliding extraction can be achieved, such as the guide rail is arranged inside the modular component, and the board is directly stuck. Since the board is assembled with the mounting plate, etc., the corresponding component of the panel can also be pulled to achieve sliding extraction.

[0056] In order to enable the board 5 to display and configure operations externally without additional wiring, in this embodiment, a light guide post hole 5172 is opened on the panel 517, and a light guide post fixing structure is arranged around the light guide post hole 5172 on the back of the panel 517, and the light guide post 9 is fixed in the light guide post fixing structure and extends out of the light guide post hole 5172. The light guide post fixing structure uses two parallel baffles matching the edges of the light guide post 9, and a transition slope is arranged on the rear side of the parallel baffles, the inner opening size of the transition slope is smaller than the margin of the installation part of the light guide post 9, and the outer opening size of the transition slope is larger than the margin of the installation part of the light guide post 9.

[0057] In order to improve the convenience of the operator, captive screws 5171 are provided at the upper and lower ends of the panel 517, and the captive screws 5171 are used to fix the modular components to the upper shell 1. When it is necessary to replace the board, the captive screws 5171 are loosened, and then the panel 517 is directly pulled outward, and the modular components are directly slid out under the action of the guide rail 516. After the replacement is completed, the convex strip 5141 is directly clamped on the guide rail 516 to push the modular components to clamp.

[0058] In this embodiment, a 3P air switch plus a plug-in box and a monitoring board modular structure are collectively referred to as a power supply unit. Therefore, the power supply unit is of universal design. One output unit can be configured with multiple power supply units as needed. Each power supply unit is powered separately, and multiple high-power outputs can be achieved. For example, this output unit can be configured with a variety of high-power output forms according to user needs, including 32~100A / single-phase, 32~100A / three-phase, 32~100A / six-phase and 32~100A / four-phase output circuits, such as Figure 2 The output circuit described above is 32~100A / four-phase. Fig.10 For 32~100A / three-phase output circuit, such as Fig.11 It is a 32-100A / six-phase output circuit. The main difference between different output circuits is the number of power taking units provided. According to the corresponding number of phases, corresponding light guide columns 9 for external display are provided on the panel 517.

[0059] In this embodiment, if Fig.12 As shown, it also includes an interlocking locking mechanism 10, through which the output unit 100 is locked and installed on the bus system 200, and the interlocking locking mechanism 10 is arranged on both sides of the box. And the mechatronic interlocking terminal distribution bus output unit combines the mechanical locking of the upper locking hook and the lower locking hook by the flipped interlocking lock plate with the electromechanical locking of the electromagnetic lock detecting the circuit breaker voltage, so as to achieve double locking and simultaneous unlocking, which greatly improves the safety of the terminal distribution bus output unit when plugging and unplugging, and does not need to match the structure with the circuit breaker.
