In some other embodiments of the present application, please refer to fig. 2, and fig. 2 is a schematic diagram illustrating another structure of an IT equipment energy-saving power supply system 100 provided in the embodiments of the present application, in which a communication high-voltage direct-current power supply guarantee system 20 includes a storage battery pack 21, a cold standby charging rectification module 22, a main charging rectification module 23, and an intelligent control module 24;
the storage battery pack 21 comprises a first pole and a second pole, the output end of the cold standby charging rectification module 22 is connected with the first pole and the second pole of the storage battery pack 21, the output end of the main charging rectification module 23 is connected with the first pole and the second pole of the storage battery pack 21, and the first pole and the second pole of the storage battery pack 21 are also respectively connected with the standby direct-current power supply module 12; the input end of the main charging rectifying module 23 and the input end of the cold standby charging rectifying module 22 are respectively connected to a power supply end (for example, a standby alternating current input end BS) through switches (K1 and K2); the intelligent control module 24 is electrically connected to the switch and the first and second poles of the battery pack 21, respectively (only a portion of the connection of the control module 24 is shown in the figure).
Specifically, fig. 2 shows a detailed structural diagram of the communication high-voltage direct-current power supply support system 20, when the utility power supply 30 is normal, the communication high-voltage direct-current power supply support system 20 is a cold standby system, and can perform floating charging and supplementary charging on the storage battery pack 21 through the main charging rectifier module 23. The input end of the main charging rectification module 23 is connected with the standby alternating current input end, when the commercial power supply 30 connected with the IT equipment is abnormal and the standby alternating current input end BS connected with the storage battery pack 21 is normal, the communication high-voltage direct current power supply guarantee system 20 is activated in function, and firstly, the main charging rectification module 23 and the storage battery pack 21 are connected in parallel to supply power to the IT equipment 10. When the commercial power supply 30 connected with the IT equipment and the standby alternating current input terminal BS connected with the main charging rectification module 23 are both abnormal, the energy stored in the storage battery pack 21 supplies power to the IT equipment. The structure is beneficial to realizing the uninterrupted power supply of the IT equipment and reasonably utilizing the electric energy of the storage battery pack 21.
After the battery pack discharges to the IT device through a large current, a situation of insufficient power may be caused. After the utility power is restored to normal, the intelligent control module 24 activates the cold standby charging rectification module 22 by detecting the change of the current of the storage battery pack (for example, whether the current direction or the current reaches a certain threshold), and the cold standby charging rectification module 22 charges the storage battery pack 21 after being started, thereby ensuring that the storage battery pack is ready for use at any time.
In some other embodiments of the present application, please refer to fig. 2 again, the power source terminal is a standby ac input terminal BS, the input terminal of the main charging rectifying module 23 is connected to the standby ac input terminal BS through a first switch K1, and the input terminal of the cold standby charging rectifying module 22 is connected to the standby ac input terminal BS through a second switch K2;
when the commercial power supply 30 electrically connected with the main alternating current power supply module 11 is abnormal in input and the BS power supply at the standby alternating current input end is normal, the main charging rectification module 23 and the storage battery pack 21 are connected in parallel to supply power to the standby direct current power supply module 12 in the IT device.
Specifically, in the communication high-voltage direct-current power supply support system 20 provided in the embodiment of the present application, the standby alternating-current input terminal BS is connected to the main charging rectifier module 23 through the first switch K1, and the cold standby rectifier module 22 is connected to the standby alternating-current input terminal BS through the second switch K2. The intelligent control module 24 controls the first switch K1 and the second switch K2 to be turned on and off. When the commercial power supply 30 connected to the standby ac input terminal BS is normal and the commercial power supply 30 connected to the IT device is abnormal, the first switch K1 is turned on, and the primary charging rectification module 23 is connected in parallel with the battery pack 21 to supply power to the IT device. Therefore, the power supply pressure of the storage battery pack 21 is effectively reduced, and the effective utilization rate of electric energy is favorably improved.
In some other embodiments of the present application, when the main ac power supply module 11 is powered by the utility power supply 30, the output voltage of the main ac power supply module 11 to the dc bus X is U1, and the output voltage of the communication high-voltage dc power supply guarantee system 20 is U2, where U1-U2 is 2V.
In the communication high-voltage direct-current power supply guarantee system 20, the storage battery pack 21 is used as a power supply for automatic discharge of standby equipment, and the storage battery can not be discharged when the voltage is set to be lower than 2V of the system at ordinary times, so that the U1-U2 is set to be 2V, and the storage battery pack 21 can be prevented from discharging when the commercial power supply 30 normally supplies power to IT equipment. Furthermore, the battery pack 21 voltage is positively correlated to the output power, and too much lower battery total power will drop too much. Therefore, the arrangement mode of U1-U2 being 2V can avoid unnecessary discharge of the storage battery pack 21 when the mains supply is normal, and can enable the storage battery pack 21 to supply power to the IT equipment at the first time when the mains supply is abnormal, so as to ensure uninterrupted power supply of the IT equipment.
Alternatively, referring to fig. 2, the first and second poles of the battery pack 21 may be further connected to diodes D1 and D2, and fuses R1 and R2, respectively. The diodes D1 and D2 are isolation diodes, and the isolation diodes can ensure that when the mains supply normally supplies power to the IT equipment, a power module in the IT equipment does not charge the storage battery pack 21, so that influence on normal work of the IT equipment is avoided.
