Description

Technical Field

[0001] This utility model relates to the field of power supply equipment technology, and in particular to a power supply system. Background Technology

[0002] Given the current popularity of artificial intelligence and the explosive growth of data storage, the power requirements of AI have reached the megawatt level. Traditional power systems are inefficient and cannot meet the power supply needs of high-power-density devices in a limited space. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing power supply systems, such as low power supply efficiency and difficulty in meeting the power supply needs of high power density devices within a limited space, and to provide a new power supply system.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a power supply system, including a cabinet, a power distribution unit disposed at the top of the cabinet, and a rectifier unit and a battery unit disposed below the power distribution unit and arranged sequentially from top to bottom; the power distribution unit includes an AC power distribution unit and a DC power distribution unit, the cabinet also has a copper busbar assembly for electrically connecting the rectifier unit and the battery unit to the power distribution unit, and the cabinet also has a grounding unit. By utilizing the AC power distribution unit of the power distribution unit to output AC power to the rectifier unit, and then using the rectifier unit to convert the AC power into DC power, the DC power is then collected by the copper busbar assembly and sent to the DC power distribution unit. The DC power is then transmitted to the IT equipment in the AI ​​data center by the DC power distribution unit. Furthermore, when the AC power distribution unit is de-energized, the battery unit outputs DC power to the copper busbar assembly, which then transmits the DC power to the DC power distribution unit. The DC power is then transmitted to the IT equipment in the AI ​​data center by the DC power distribution unit. This allows the power system to supply both AC and DC power to the IT equipment in the AI ​​data center, effectively improving the power supply efficiency. In addition, by placing the power distribution unit at the top of the cabinet and arranging the rectifier unit and battery unit below it from top to bottom, the utilization rate of the cabinet's internal space can be effectively improved, further enhancing the power supply efficiency of the power system and enabling the power supply needs of high-power-density equipment to be met within a limited space.

[0005] Furthermore, the AC power distribution unit includes an AC input cable for AC power input, an AC input connector electrically connected to the AC input cable, an AC power distribution module, an AC output cable electrically connected to the rectifier unit, and an AC output connector electrically connected to the AC output cable. The outer frame of the AC power distribution unit is locked to the cabinet by locking components. AC power is connected to the AC input cable, flows through the AC input connector into the AC power distribution module, exits through the AC output connector, and is then fed into the rectifier unit via the AC output cable. The AC power distribution unit includes eight AC power distribution modules arranged side-by-side. Each module can divide three AC inputs into four AC outputs, thus achieving 32 AC outputs, effectively improving the power supply efficiency of the power system. The overall height of the AC power distribution unit is 8OU. This allows for an increase in the number of AC output lines within a limited space, effectively improving the AC output efficiency of the AC power supply unit.

[0006] Furthermore, the AC power distribution unit also includes an AC input brush through which the AC input cable passes. After passing through the AC input brush, the AC input cable is electrically connected to the AC input connector, thereby effectively utilizing the AC input brush to prevent dust from entering the AC power distribution unit, thus ensuring the cleanliness of the cabinet interior and the safety of the AC power distribution unit.

[0007] Furthermore, the rectifier unit includes several rectifier modules, which are electrically connected to the AC output cable and to the DC power distribution unit via the copper busbar assembly. The AC power output from the AC power distribution unit flows into the rectifier modules of the rectifier unit through the AC output cable. These rectifier modules convert the three-phase AC power distributed by the AC power distribution unit into 400V high-voltage DC power, which is then fed into the DC power distribution unit via the copper busbar assembly. Subsequently, the DC power is transmitted to the IT equipment in the AI ​​data center through the DC power distribution unit. The rectifier unit includes five rectifier modules arranged from top to bottom, with a total height of 10OU, effectively reducing the space required by the rectifier unit and further improving the space utilization within the server rack while meeting the rectification requirements of the AC power distribution unit.

[0008] Furthermore, the copper busbar assembly includes a long vertical copper busbar located at the rectifier unit and battery unit, a short vertical copper busbar located at the DC power distribution unit, and a connecting copper busbar disposed between the long and short vertical copper busbars. The DC power output from the rectifier unit and battery unit flows into the connecting copper busbar through the long vertical copper busbar, and then converges through the connecting copper busbar into the short vertical copper busbar located at the DC power distribution unit. From there, the DC power is transmitted to the IT equipment in the AI ​​data center via the DC power distribution unit. The bottom of the long vertical copper busbar is fixedly connected to the bottom shell of the cabinet using locking devices, while the middle and top of the long vertical copper busbar are fixedly connected to the crossbeams of the cabinet using locking devices, effectively ensuring the stability of the long vertical copper busbar within the cabinet. The short vertical copper busbar is fixed to the crossbeams of the cabinet using locking devices, effectively ensuring the stability of the vertical section of the copper busbar within the cabinet.

[0009] Furthermore, the DC power distribution unit includes a DC input connector electrically connected to the vertical short copper busbar, a DC power distribution module, a DC output connector electrically connected to the vertical long copper busbar, and a DC output cable for electrically connecting the equipment in the rack to the DC output connector. The DC power output from the rectifier unit and battery unit flows into the vertical long copper busbar through the DC output connector, and then through the connecting copper busbar to the vertical short copper busbar located at the DC power distribution unit. Subsequently, it flows into the DC power distribution module through the DC input connector, and is transmitted to the IT equipment in the AI ​​data center through the DC output cable. The DC power distribution unit includes four DC power distribution modules arranged sequentially from top to bottom, with a total height of 8OU, thereby further improving the space utilization within the rack. The DC power distribution unit is installed in the rack via a DIN rail adapter, effectively improving the ease of installation within the rack.

[0010] Furthermore, the DC power distribution unit also includes a DC output brush through which the DC input cable passes. After the AC input cable passes through the AC input brush, it transmits DC power to the IT equipment in the AI ​​data center. This effectively utilizes the DC output brush to prevent dust from entering the DC power distribution unit, thus ensuring the cleanliness of the cabinet interior and the safety of the DC power distribution unit.

[0011] Furthermore, the battery unit includes several battery modules, which are electrically connected to the DC power distribution unit via the copper busbar assembly. When the AC power distribution unit is powered off, the DC power output from the battery modules of the battery unit is transmitted through a DC output connector to a vertical long copper busbar, then through a connecting copper busbar to a vertical short copper busbar located at the DC power distribution unit. Subsequently, the DC power flows into the DC power distribution module through a DC input connector, and is transmitted to the IT equipment of the AI ​​data center via a DC output cable. This enables the power system to supply DC power to the IT equipment of the AI ​​data center from the battery unit, thereby effectively improving the power supply efficiency of the power system.

[0012] Furthermore, the grounding unit includes a grounding cable, a rubber guide block through which the grounding cable passes, and a grounding copper busbar electrically connected to the grounding cable. By passing the grounding cable through the rubber guide block and electrically connecting it to the grounding copper busbar, the overall safety of the power system can be effectively ensured.

[0013] Furthermore, the cabinet is equipped with a front door and a rear door, with the DC power distribution unit located at the front door and the AC power distribution unit located at the rear door. By placing the DC power distribution unit at the front door and the AC power distribution unit at the rear door, the safety of the power distribution units inside the cabinet can be ensured while effectively improving the convenience for operators to perform maintenance operations on the DC and AC power distribution units.

[0014] The beneficial effects of the power supply system provided by this utility model are as follows: By utilizing the AC power distribution unit of the power distribution unit to output AC power to the rectifier unit, and using the rectifier unit to convert the AC power into DC power, the DC power is then collected by the copper busbar assembly to the DC power distribution station, and the DC power is transmitted to the IT equipment of the AI ​​data center by the DC power distribution unit. Furthermore, when the AC power distribution unit is powered off, the battery unit outputs DC power to the copper busbar assembly, and the copper busbar assembly transmits the DC power to the DC power distribution station, and the DC power is transmitted to the IT equipment of the AI ​​data center by the DC power distribution unit. This achieves the method of supplying power to the IT equipment of the AI ​​data center with both AC and DC power inputs, thereby effectively improving the power supply efficiency of the power supply system. In addition, by setting the power distribution unit at the top of the cabinet and placing the rectifier unit and battery unit below the power distribution unit from top to bottom, the utilization rate of the cabinet's internal space can be effectively improved, thereby further improving the power supply efficiency of the power supply system and meeting the power supply needs of high power density equipment in a limited space.

The power distribution unit includes an AC power distribution unit 20 and a DC power distribution unit 40. The cabinet 10 also has a copper busbar assembly 50 for electrically connecting the rectifier unit 30 and the battery unit 60 to the power distribution unit. The cabinet 10 also has a grounding unit 70. The power system 100 provided by this utility model is an HVDC (High Voltage Direct Current) power system. This power system 100 uses the AC distribution unit 20 of the power distribution unit to output AC power to the rectifier unit 30, where the rectifier unit 30 converts the AC power into DC power. The DC power is then collected by the copper busbar assembly 50 and transmitted to the DC power distribution station via the DC power distribution unit 40. Furthermore, when the AC distribution unit 20 is de-energized, the battery unit 60 outputs DC power to the copper busbar assembly 50, which then transmits the DC power to the DC power distribution station. By utilizing the DC power distribution unit 40 to transmit DC power to the IT equipment in the AI ​​data center, the power system 100 can supply power to the IT equipment in the AI ​​data center through both AC and DC inputs, thereby effectively improving the power supply efficiency of the power system 100.

The outer frame of the AC power distribution unit 20 is locked and fixed to the cabinet 10 by locking components. AC power is connected to the AC input cable 21, flows through the AC input connector 23 into the AC power distribution unit 22, and then flows out of the AC power distribution unit 22 through the AC output connector 25 and is transmitted to the rectifier unit 30 via the AC output cable 21. The AC power distribution unit 20 includes eight sets of AC power distribution units 22 arranged side by side.

The rectifier modules are electrically connected to the AC output cable 21 and to the DC power distribution unit 40 via the copper busbar assembly 50. The AC power output from the AC power distribution unit 20 flows into the rectifier modules of the rectifier unit 30 through the AC output cable 21. The rectifier modules convert the three-phase AC power distributed by the AC power distribution unit 20 into 400V high-voltage DC power, which is then fed into the DC power distribution unit 40 via the copper busbar assembly 50. Subsequently, the DC power is transmitted to the IT equipment in the AI ​​data center through the DC power distribution unit 40. The rectifier unit 30 includes five rectifier modules arranged from top to bottom, with a total height of 10OU, thereby effectively compressing the space required by the rectifier unit 30.

The DC power output from the rectifier unit 30 and the battery unit 60 flows into the connecting copper busbar 52 through the vertically long copper busbar 51, and then converges into the vertically short copper busbar 53 located at the DC power distribution unit 40 through the connecting copper busbar 52. The DC power then flows into the DC power distribution unit 40 through the vertically short copper busbar 53, and is subsequently transmitted to the IT equipment of the AI ​​data center through the DC power distribution unit 40. The bottom of the vertically long copper busbar 51 is fixedly connected to the bottom shell of the cabinet 10 by locking components, and the middle and top of the vertically long copper busbar 51 are fixedly connected to the crossbeam 13 of the cabinet 10 by locking components, thereby effectively ensuring the stability of the vertically long copper busbar 51 fixed within the cabinet 10.

The DC power is then transmitted to the IT equipment of the AI ​​data center via the DC output cable 44. This enables the power system 100 to supply power to the IT equipment of the AI ​​data center via the DC input of the battery unit 60, thereby effectively improving the power supply efficiency of the power system 100.
