Description

Technical Field

[0001] This invention proposes an intelligent power distribution device and its working method that support power supply for multiple rows, relating to the field of electrical equipment technology. Background Technology

[0002] Rack power distribution units (rPDUs) are used to distribute power to the equipment inside server racks. Server racks cover a wide range of application scenarios, including artificial intelligence (AI), high-performance computing (HPC), network equipment, storage devices, and application hosting. The configurations of the equipment inside the racks vary greatly, so the requirements for power distribution units (PDUs) are also different.

[0003] To meet diverse needs, the cabinet power distribution unit is divided into a large number of independent SKUs, each adapted to different input power, branch circuit protection, socket type (such as IEC C13, C19), number of sockets, and intelligent functions such as single-port monitoring and single-port remote on / off. Each dedicated socket + circuit breaker combination solution requires independent hardware design, which usually involves significant modifications to the printed circuit board (PCB) layout and mechanical structure.

[0004] Traditional intelligent cabinet power distribution units use a fixed internal architecture: sockets are pre-grouped, and each group of sockets is matched with a specific branch circuit breaker, along with dedicated monitoring and on / off circuits. Therefore, even if the core functions remain unchanged, any changes to the number of sockets, their arrangement, or the circuit breaker configuration must require a redesign of critical circuit board components and the chassis structure.

[0005] This fixed architecture brings many drawbacks: large R&D workload, long product development and certification cycles, complex inventory models, high manufacturing costs, and heavy supply chain management pressure, while long-term operation and maintenance costs remain high. For small-batch, customer-customized special configuration models, traditional solutions are extremely uneconomical, forcing data center operators to choose standard power distribution units, which cannot fully match their own business scenarios, resulting in idle and wasted equipment resources.

[0006] In summary, the industry needs a new cabinet power distribution unit socket architecture that can be compatible with more socket, circuit breaker, monitoring, and on / off function combinations without large-scale hardware modifications. Summary of the Invention

[0007] In view of this, in order to fill the gaps and deficiencies in the prior art, the present invention proposes an intelligent power distribution device and its working method that supports power supply for multiple rows, so as to effectively solve the problems mentioned in the background art.

[0008] This invention proposes an intelligent power distribution device and its working method that support power supply for multiple rows, including the following:

[0009] According to a first aspect of the present invention, an intelligent power distribution device supporting multiple power supply rows is proposed, characterized in that it includes several multi-row power distribution modules, a control module, a sheet metal body, and a power access module; wherein the multi-row power distribution modules and the control module are all installed in the mounting slots of the sheet metal body and fixed by bolts or clips; wherein the multi-row power distribution module includes an output power distribution board, a relay control board, a data acquisition board, a power socket base plate, a power socket, and a power module sheet metal; wherein the power access module includes an external interface; wherein the reserved holes of the power module sheet metal support the access of at least one power socket, and support the access of the output power distribution board, relay control board, data acquisition board, and power socket base plate corresponding to the number of at least one power socket to achieve multiple power supply rows.

[0010] Furthermore, the external interface of the power access module supports cable termination or plug connection; the power access module supports single-phase, three-phase four-wire, or three-phase five-wire power input.

[0011] Furthermore, the installation method of the multi-row power distribution module includes: with the output power distribution board as the top and the power module sheet metal as the bottom, the components from top to bottom are: output power distribution board, relay control board, acquisition board, power socket base plate, power socket, and power module sheet metal; wherein the output power distribution board, relay control board, acquisition board, power socket base plate, power socket, and power module sheet metal are all fixedly installed in pairs using connecting devices; wherein the connecting devices include bolts, clips, and connectors;

[0012] The installation direction of the power socket and the sheet metal of the power module is as follows: the socket of the power socket contacts and is flush with the reserved hole of the sheet metal of the power module, so that the socket of the power socket faces outward without obstruction.

[0013] Furthermore, the method of installing the multi-row power distribution module on the sheet metal body also includes: during the process of embedding the multi-row power distribution module into the mounting slot of the sheet metal body, the external power supply is connected to the output power distribution board through the wiring harness, and the socket of the power socket and the reserved hole of the power module sheet metal face outward.

[0014] Furthermore, the output power distribution boards of several multi-row power distribution modules form an electrically conductive loop with the internal power interface of the power access module through a wiring harness; thus realizing electrical conduction from the external interface of the power access module to the output power distribution board.

[0015] Furthermore, the control module includes a network interface, a USB interface, and an LCD display screen; wherein the network interface supports different types of network cable access.

[0016] Furthermore, when the multi-row power distribution modules provide mixed power, the control module supports simultaneously controlling the power on and off of at least one power socket.

[0017] According to a second aspect of the present invention, the present invention provides a method for operating an intelligent power distribution device that supports power supply for multiple power rows, applied in an intelligent power distribution device that supports power supply for multiple power rows as described in any one of the present invention, characterized in that it includes the following:

[0018] Select a multi-row power distribution module with at least one power socket; install several multi-row power distribution modules into the sheet metal body, and then supply power to the intelligent power distribution device through the power access module. Finally, the control module controls the increase and decrease of the number of external power supply ports of the intelligent power distribution device by controlling the energized and de-energized states of the relays, so as to realize multi-row power supply according to different working conditions.

[0019] The present invention has the following advantages:

[0020] This invention designs a multi-row power distribution module as a general basic unit, which can be combined to build cabinet power distribution units with different numbers and types of sockets, circuit breaker distribution logic, and intelligent function combinations.

[0021] Each multi-row power distribution module of this invention includes one or more rows of power sockets, and the supporting circuit can realize single-circuit socket monitoring and single-circuit socket remote on / off (either one can be selected, all can be equipped or all can be omitted), and all modules adopt a unified electrical interface.

[0022] This invention allows for adjustments to the total number of sockets and changes to their correspondence by adding, removing, or rearranging multiple rows of power distribution modules. It eliminates the need for developing separate electrical hardware for each type of socket; new cabinet power distribution unit models can be derived simply by selecting and arranging standardized socket modules.

[0023] In addition, the architecture of this invention can simultaneously accommodate multiple socket and circuit breaker configurations within a single device, and the hardware platform is completely universal. Attached Figure Description
