Utility Model Content
[0003] The purpose of this utility model is to solve the shortcomings of existing data center power distribution cabinets on the market, such as low power distribution efficiency, complex structure, large space occupation, and difficulty in meeting the rectification and power distribution needs of high power density equipment in a limited space, and to provide an AC power distribution cabinet.
[0004] The technical solution adopted by this utility model to solve its technical problem is: an AC power distribution cabinet, including a cabinet body and a plurality of AC power distribution units arranged from top to bottom in the cabinet body; the front end of the AC power distribution unit is provided with an AC input cable and an AC input hub assembly, and the rear end of the AC power distribution unit is provided with an AC output cable and an AC output hub assembly. The AC power distribution unit includes a power distribution housing, a female AC input connector disposed on the power distribution housing and used for electrical connection with the AC input cable, and a protection module electrically connected to the female AC input connector and the AC output cable. By arranging several AC power distribution units from top to bottom within the cabinet and electrically connecting them to AC output cables using AC input cables and protection modules, the space utilization within the cabinet can be effectively improved, increasing the layout density of the AC power distribution units. This allows for meeting the power distribution needs of high-power-density equipment within a limited space. Furthermore, the protection modules effectively provide short-circuit protection for the AC power distribution units, enhancing their safety. Additionally, this AC power distribution cabinet allows for the independent operation of the AC power distribution units from the data center's power distribution cabinet. The AC power distribution units are compatible with different input currents and can simultaneously support multiple AC inputs, further increasing the power density and enhancing the applicability of the AC power distribution cabinet.
[0005] Furthermore, the AC input cable includes a cabinet input connector for electrical connection to external devices, a male AC input connector for electrical connection to the cabinet input connector, and a cabinet input cable connecting the cabinet input connector and the male AC input connector. The cabinet input connector of the AC input cable provided by this invention is fixed to the cabinet and located at the front end of the AC power distribution unit using bolts, studs, and pins, thereby effectively improving the convenience of electrical connection between external devices and the cabinet input connector. External devices input AC power into the AC input cable through the cabinet input connector, and then into the AC power distribution unit through the male AC input connector, thereby effectively improving the convenience and stability of AC power input and transmission in the AC power distribution cabinet.
[0006] Furthermore, the AC power distribution unit includes a power distribution housing, a changeover switch disposed on the power distribution housing, a female AC input connector for electrical connection with the male AC input connector, and a power distribution copper busbar and power distribution cable disposed within the power distribution housing for electrical connection of the female AC input connector to the protection module.

By electrically connecting the female AC input connector on the protection housing to the male input connector of the AC input cable, the operation of inputting AC power into the AC power distribution unit can be realized. Subsequently, using the power distribution copper busbar and power distribution cable disposed within the protection housing, the operation of inputting AC power into the protection module can be realized. Meanwhile, by utilizing a protective switch, a compatible AC input mode can be achieved, allowing for either one 200A AC input or two 100A AC inputs. When the input current is 200A, the transfer switch closes, enabling one AC input; when the input current is 100A, the transfer switch opens, enabling two AC inputs. This allows the AC distribution unit to be compatible with different input currents and simultaneously support multiple AC inputs, further improving the power density of the AC distribution cabinet and enhancing its applicability and compatibility.
[0007] Furthermore, the protection module includes a protective housing, several protective components disposed within the protective housing, a protective input connector for electrical connection with the power distribution cable, and a protective output connector for electrical connection with the AC output cable.

[0008] Furthermore, the protection input connector is electrically connected to the protection component via a protection input copper busbar and a protection input cable, and the female output connector is electrically connected to the protection component via a protection output cable. By using the protection input copper busbar and protection input cable to electrically connect the protection input connector to the protection component, and using the protection output cable to electrically connect the female output connector to the protection component, the stability of the AC current from the AC power distribution unit being transmitted to the AC output cable via the protection module can be effectively ensured, while also effectively improving the space utilization within the protection housing.
[0009] Furthermore, the protective housing also includes an auxiliary power supply and several fans. In the embodiments provided by this invention, the auxiliary power supply can draw power directly from the protective components within the protective housing, thereby powering the fans within the protective housing and the components on the protective housing, effectively achieving the heat dissipation function of the protection module and improving its safety.
[0010] Furthermore, the protective housing is also equipped with voltage detection terminals, a handle, several indicator lights, and latches for installing the protective housing into the cabinet. By connecting a voltage detection device through the voltage detection terminals, relevant data of the protection module can be effectively monitored, and the working status can be indicated by several indicator lights, thereby further improving the overall safety of the protection module and the AC power supply cabinet. Furthermore, using the latches to install the protection module into the cabinet effectively improves the stability of the protection module installation while also increasing the ease of installation. And by pushing and pulling the handle on the protective housing, the ease of pushing the protection module into and removing it from the cabinet is significantly improved.
[0011] Furthermore, the AC output cable includes an AC output connector electrically connected to the protection output connector, a cabinet output connector for electrical connection to external devices, and a cabinet output cable for electrically connecting the AC output connector and the cabinet output connector. The cabinet output connector of the AC output cable provided by this invention is fixed to the cabinet and located at the rear end of the AC power distribution unit using bolts, studs, and pins, thereby effectively improving the convenience of electrical connection between external devices and the cabinet output connector. By electrically connecting the AC output connector to the protection output connector, the operation of inputting AC power flowing through the protection module into the AC output cable can be realized. After inputting into the cabinet output connector via the cabinet output cable, the operation of powering external devices can be realized by electrically connecting the external devices to the cabinet output connector, thereby effectively improving the stability of powering external devices using the AC output cable.
