[0023] As briefly mentioned earlier, traditional integrated power distribution devices have complex structures and low adaptability to various functional modules. Therefore, they cannot meet the current complex power distribution needs.

[0024] This disclosure provides an integrated power distribution device and cabinet to solve, or at least partially solve, the aforementioned problems and other potential problems existing in conventional solutions. According to the integrated power distribution device provided by this disclosure, multiple functional modules are slidably installed within a rack, and when inserted into the rack, these modules are connected to busbars and communication lines within the integrated power distribution device. In this way, users can select and install appropriate functional modules according to actual application needs, thereby improving the ease of use of the power distribution device.

[0025] The power distribution cabinet provided according to embodiments of this disclosure generally includes a cabinet and at least one power distribution device disposed within the cabinet. The power distribution device is connected to at least a power supply bus and a signal line to realize the power distribution function to the load side.

[0026] Figure 1 A schematic diagram of the overall structure of an integrated power distribution device according to some embodiments of the present disclosure is shown. Figure 2 and Figure 3Schematic diagrams of the front and rear structures of an integrated power distribution device according to some embodiments of the present disclosure are shown respectively. Figures 1 to 3 As shown, the integrated power distribution device generally includes a rack 1, multiple functional modules 2 arranged in the rack 1, a busbar 3 arranged on the wiring side of the rack 1 and coupled to the multiple functional modules 2, and a communication busbar 4.

[0027] The rack 1 includes a receiving cavity 11 formed within the rack 1 and adapted to connect the operating side of the rack 1 to the wiring side of the rack 1. A plurality of functional modules 2 are arranged within the receiving cavity 11 along an arrangement direction X. The functional modules 2 are slidably connected to the inner wall of the receiving cavity 11 so that the functional modules 2 can enter and exit the receiving cavity 11 along an installation direction Z perpendicular to the arrangement direction X. A bus 3 and a communication bus 4 are coupled to the functional modules 2 slidably into the receiving cavity 11, respectively. Thus, the bus 3 can supply power to the functional modules 2, and the communication bus 4 can communicate with the functional modules 2. In some embodiments, the bus 3 and the communication bus 4 are arranged along a vertical direction Y perpendicular to the arrangement direction X.

[0028] In some embodiments, functional module 2 includes at least one of a circuit breaker unit, a gateway unit, and a solid-state switch unit. The circuit breaker unit is adapted to detect the power consumption status of the connected lines and disconnect the lines during periods of abnormal power consumption. The gateway unit can communicate with the circuit breaker unit via communication bus 4 and can locally store the power consumption status of the lines connected to the circuit breaker unit and the operation status of the circuit breaker unit. The solid-state switch unit can connect or disconnect the lines based on control signals.

[0029] Furthermore, the gateway unit can also communicate with external devices via communication panel 4. For example, the gateway unit can upload data stored in its own body related to line power consumption and circuit breaker operation to a remote server. In some embodiments, the multiple functional modules 2 within rack 1 may include a gateway unit and multiple circuit breaker units. In some embodiments, the multiple functional modules 2 within rack 1 may include a gateway unit and multiple solid-state switch units. In some other embodiments, the multiple functional modules 2 may also include multiple circuit breaker units or multiple gateway units.

[0030] To improve the flexibility of the arrangement of circuit breaker units and gateway units within rack 1, in some embodiments, the gateway unit is further configured such that its width along the arrangement direction X is an integer multiple of the width of the circuit breaker unit along the arrangement direction X. For example, the width of the gateway unit can be three times the width of the circuit breaker unit, thereby allowing the gateway unit and the circuit breaker unit to be arranged within rack 1 in any suitable manner. Similarly, in some embodiments, the gateway unit can also be configured such that its width along the arrangement direction X is an integer multiple of the width of the solid-state switch unit along the arrangement direction X.

[0031] In some embodiments, the gateway unit can be arranged at any end of the plurality of circuit breaker units along the arrangement direction X. In some other embodiments, the gateway unit can also be arranged between two circuit breaker units. In this way, the flexibility and convenience of the field installation layout of the integrated power distribution unit can be improved.

[0032] Figure 4 Exploded views are shown according to some disclosed embodiments. Figure 4 As shown, in some embodiments, the functional module 2 and the frame 1 are slidably connected. Specifically, the functional module 2 includes a body and a sliding protrusion 22 protruding from the body in the vertical direction Y. The sliding protrusion 22 extends in the installation direction Z. Correspondingly, the frame 1 also includes a pair of limiting rails 12. The pair of limiting rails 12 are arranged in the receiving cavity 11 and protrude from the inner wall of the receiving cavity 11.

[0033] Each limiting rail 12 extends along the installation direction Z, and pairs of limiting rails 12 are arranged along the arrangement direction X and spaced apart by a predetermined distance. Thus, when the functional module 2 slides into the frame 1, the sliding protrusion 22 can slide into the gap between the pairs of limiting rails 12 and move along the installation direction Z under the constraint of the limiting rails 12, thereby allowing the functional module 2 to enter the receiving cavity 11 along the installation direction Z. During on-site installation or maintenance, personnel can disassemble or install the functional module 2 from the frame 1 by sliding, thereby improving the convenience of installation and maintenance of the integrated power distribution device.

[0034] In some embodiments, the sliding protrusions 22 of the functional module 2 can be arranged in pairs. The pairs of sliding protrusions 22 are respectively arranged on the sidewalls at both ends of the body along the vertical direction Y, and the pairs of sliding protrusions 22 protrude from the body in opposite directions. Multiple limiting rails 12 within the frame 1 are respectively arranged on the inner walls at both ends of the receiving cavity 11 along the vertical direction Y, and cooperate with the pairs of sliding protrusions 22. Through the cooperation of the sliding protrusions 22 at both ends of the body with the corresponding limiting rails 12, the stability of the functional module 2 sliding within the frame 1 can be further improved.

[0035] In some embodiments, the frame 1 further includes a plurality of guide protrusions 13 protruding into the receiving cavity 11 and arranged between pairs of limiting rails 12. Both ends of the guide protrusions 13 extend toward the end of the limiting rail 12 near the operating side of the frame 1, and the middle portion of the guide protrusions 13 bends toward the operating side of the frame 1. In this way, during the insertion of the functional module 2 into the receiving cavity 11, the guide protrusions 13 can contact the sliding protrusions 22. Guided by the guide protrusions 13, the sliding protrusions 22 smoothly enter the gap between the pairs of limiting rails 12, thereby improving the ease of installation of the working module.

[0036] In some embodiments, the functional module 2 further includes a pair of mounting holes 21 formed on the body and located near both ends of the body along the vertical direction Y. The axis of the mounting holes 21 is parallel to the mounting direction Z. A fastener 5 passes through the mounting holes 21 and is coupled to the frame 1. Thus, after the working module is inserted into the receiving cavity 11, the mounting component can be fixed to the frame 1 by coupling the fastener 5 to the frame 1. In some embodiments, the fastener 5 can be a bolt, which passes through a fastening hole and engages with the threaded connection of the bolt to the frame 1, thereby fixing the working module to the frame 1.

[0037] In some embodiments, the integrated power distribution unit further includes a cable tray bracket 6, which is arranged on the wiring side of the rack 1 and adapted to at least partially accommodate the busbar 3. The cable tray bracket 6 is coupled to the bracket to fix the busbar 3, which on the one hand supports the busbar 3 so that the busbar 3 can be coupled to the functional module 2 when the functional module 2 is inserted into the bracket, and on the other hand, the cable tray bracket 6 wrapping around the outside of the busbar 3 can improve the electrical safety of the integrated power distribution unit.

[0038] In some embodiments, the communication strip 4 includes a plurality of communication interfaces 41 extending along the mounting direction Z toward the functional modules 2. During coupling of the functional modules 2 to the rack 1, the communication interfaces 41 can be at least partially inserted into the corresponding functional modules 2, thereby enabling the functional modules 2 to communicate via the communication strip 4. In some embodiments, the communication strip 4 is a printed circuit board, and corresponding electrical components are integrated on the communication strip 4. The communication interfaces 41 may be conductive contacts formed on the printed circuit board.
