For example, the different types of current may include direct current, alternating current. The direct current may be an uninterruptible direct current, and the alternating current may include an uninterruptible alternating current.

In one example, as shown in fig. 1, the power supply cabinet may include a plurality of power input modules (e.g., the utility power input module 101 and the oil engine power input module 102 in fig. 1), a power metering conversion module 103, a power distribution module 104, a first ac power feed module 105, a rectification module 106, and an uninterruptible power supply module 107.

One end of each of the plurality of power input modules is connected to a plurality of power sources, and the other end of each of the plurality of power input modules is connected to the power metering conversion module 103. For example, in fig. 1, a first end of the mains power input module 101 may be connected to the mains power, and a second end may be connected to a first end of the power metering conversion module 103. The first end of the fuel engine power input module 102 may be connected to a generator and the second end may be connected to a first end of the power metering conversion module 103.

The commercial power input module 101 and the fuel engine power module 102 may be 380 volt (V) modules. That is, the voltage of the commercial power after passing through the commercial power input module 101 and the voltage of the generator after passing through the oil engine power module 102 are all 380V.

In a possible design, the power supply cabinet in the embodiment of the present application may further be provided with a transformer. The transformer can be arranged in the power cabinet, and can also be arranged separately from the power cabinet without limitation. The transformer may convert the voltage. For example, the transformer is a 10kV/380V transformer, and when the mains voltage is 10kV, the transformer may convert the mains voltage into 380V. Therefore, the power supply device can adapt to the scene of supplying power to the equipment in the communication machine room.

Wherein, the second end of the power metering and converting module 103 can be connected with the first end of the power distribution module 104. The power metering and converting module 103 may be configured to count parameter information of the commercial power and the power output duration, the power transmission amount, the power outage duration, the output voltage and the current of the generator, and may be further configured to switch the power input to the power distribution module 104. For example, when the utility power is abnormal, such as the utility power is cut off, the power metering and converting module 103 may disconnect the connection with the utility power and connect with the generator in the power generation state; when the utility power is normal, the power metering and converting module 103 may be disconnected from the generator and connected to the utility power.

In this embodiment, the voltage of the output of the power metering conversion module 103 may be an ac voltage.

The second end of the power distribution module 104 may be connected to the first end of the first ac power feeding module 105, the first end of the rectifying module 106, and the first end of the uninterruptible power supply module 107, respectively. The power distribution module may be used to multiplex the power from the power metering conversion module 103. The power supply of each power supply can be the same or different.

In one possible design, as shown in fig. 1, the power distribution module 104 may include an ac busbar and an ac power distribution module. The first end of the alternating current busbar is connected with the power supply metering conversion module 103, and the second end of the alternating current busbar is connected with the first end of the alternating current power supply distribution module. The second end of the ac power distribution module is connected to the first end of the first ac power feeding module 105, the first end of the rectifying module 106, and the first end of the ups module 107, respectively.

It should be noted that the power supply cabinet may output one or two of the above three types of power supplies, and may be set as needed, without limitation.

Wherein, the second end of the rectifying module 106 is connected to the first end of the dc feeding module 108. A second terminal of the ups module 107 is connected to a first terminal of a second ac feed module 109.

Wherein, the first alternating current and the second alternating current may be 380V. The direct current may be-48V, 240V, 336V.

In one possible design, the first ac power may supply power to electrical devices (e.g., electricity, monitoring devices, lighting devices) in a supporting office of the communication room. The second ac power may be used to power the communication device or an auxiliary device (e.g., an air conditioner) that ensures proper operation of the communication device. The direct current can be used to power a communication device.

It should be noted that the direct current and the second alternating current output by the power supply cabinet provided in the embodiment of the present application may be uninterruptible currents. In this way, it is ensured that the devices connected to the first ac power feeding module 105 and the dc power feeding module 108 can be in a normal operating state for a long time.

In one possible design, in order to ensure that the output current of the first ac power feeding module 105 and the dc power feeding module 108 is uninterrupted current, as shown in fig. 1, the power supply cabinet may further include a first control switch 110 and a second control switch 111.

It should be noted that, when the first control switch 110 is in a closed state, the battery pack is communicated with the rectifier module 106, and the battery pack can output current to the rectifier module 106. When the second control switch 111 is in a closed state, the battery pack is connected to the ups module 107, and the battery pack can output current to the ups module 107. Therefore, the power supply cabinet can supply power to the equipment through the storage battery pack under the condition that the commercial power and the generator cannot output power, so that the power supply cabinet can normally supply power to the equipment within a long time.

Further, the rectifier module 106 and the ups module 107 may be configured to collect voltage, and capacity of the battery pack, and control the operating state of the battery. The capacity of the rectifier module 106 may be set as desired, and may be, for example, not less than 10 KVA.

For example, when the rectifier module 106 and the uninterruptible power supply module 107 detect that the output power or the output current of the battery pack is abnormal or the battery is short-circuited, the connection with the battery may be disconnected; the battery or other energy storage device may be charged when the remaining charge detected by the rectifier module 106 and the ups module 107 is below a threshold capacity.

It should be noted that, when the multiple power supplies are normal, the first control switch 110 and the second control switch 111 may be in a conducting state, and at this time, the storage battery or other energy storage devices may be charged; when the electric energy of the storage battery or other energy storage devices is in a full state, the storage battery or other energy storage devices can be in a floating charging state; when the battery or other energy storage device is abnormal, the battery is short-circuited, and the controller 114 may disconnect the battery or other energy storage device from the power supply cabinet, for example, input a level to the first control switch 110 and the second control switch 111, where the level may be used to keep the first control switch 110 and the second control switch 111 in an off state.
