Description

Technical Field

[0001] The present application relates to the field of power supply technology, and in particular to a power supply system and a data center. Background Art

[0002] In the related art, a 1+1 redundant power supply mode is usually used to power the loads of a data center. The two circuits of the 1+1 redundant power supply mode supply power to one load at the same time, and the two power grids can be connected through a busbar cabinet. When both circuits are powered normally, the busbar switch in the busbar cabinet is in an open state. When one of the circuits fails, the busbar switch of the busbar cabinet is closed, so that the other normal circuit supplies power to the faulty circuit. However, the busbar cabinet is expensive and large in size, resulting in high cost and large footprint of the power supply system. At the same time, since it takes a certain amount of time to switch the busbar switch, it is easy for subsequent critical loads to restart or shut down due to power outages. Utility Model Content

When one of the power supplies stops supplying power due to a fault, the other power supply can also continue to supply power to the load through the first power input interface and the second power input interface at the same time, ensuring that the load does not experience power interruption and preventing the load from restarting or shutting down due to power outages.

[0037] For details, please refer to Figure 1 to Figure 2 , an embodiment of the present application provides a power supply system. The power supply system includes a first power supply 10, a second power supply 20, a first rectifier output cabinet 310, a second rectifier output cabinet 410, a third rectifier output cabinet 320 and a fourth rectifier output cabinet 420. Among them, the first rectifier output cabinet 310 and the third rectifier output cabinet 320 are both electrically connected to the first power supply 10. The second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 are both electrically connected to the second power supply 20. Among them, the output end of the first rectifier output cabinet 310 is connected in parallel with the output end of the second rectifier output cabinet 410 to form a first parallel end, and the first parallel end is used to electrically connect the first electrical input interface 510 of the load 50, and the output end of the third rectifier output cabinet 320 is connected in parallel with the output end of the fourth rectifier output cabinet 420 to form a second parallel end, and the second parallel end is used to electrically connect the second electrical input interface 520 of the load 50.

[0038] In this embodiment, the current of the first power source 10 is output in two ways through the first rectifier output cabinet 310 and the third rectifier output cabinet 320, so that the first power source 10 can simultaneously supply power to the first power input interface 510 and the second power input interface 520 of the load 50. The current of the second power source 20 is output in two ways through the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420, so that the second power source 20 can simultaneously supply power to the first power input interface 510 and the second power input interface 520 of the load 50. When one of the power supplies stops supplying power due to a fault, for example, when the second power supply stops supplying power due to a fault, the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 cannot supply power to the loads corresponding to the first electrical input interface 510 and the second electrical input interface 520 respectively, and the other power supply can also continuously supply power to the load 50 through the first electrical input interface 510 and the second electrical input interface 520 at the same time, that is, currently only the first power supply supplies power to the loads corresponding to the first electrical input interface 510 and the second electrical input interface 520 through the first rectifier output cabinet 310 and the third rectifier output cabinet 320, ensuring that the load 50 does not experience power interruption, and preventing the load 50 from restarting or shutting down due to power failure. At the same time, the use of the mother coupling cabinet is eliminated, which can reduce the floor space and reduce costs.

[0039] The load 50 may be an IT load, so that the power supply system can be applied to a data center. When the power supply system is applied to other power supply devices, the load 50 may also be other types of loads 50, such as lighting loads, display loads, etc.

[0040] The first rectifier output cabinet 310, the third rectifier output cabinet 320, the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 are all rectifier cabinets. The rectifier cabinet is mainly used to convert alternating current into direct current.

[0041] In some embodiments, the number of the first rectifier output cabinets 310 is set to at least two. The number of the second rectifier output cabinets 410, the third rectifier output cabinets 320, and the fourth rectifier output cabinets 420 is adapted to the number of the first rectifier output cabinets 310. That is, the number of the second rectifier output cabinets 410, the third rectifier output cabinets 320, and the fourth rectifier output cabinets 420 is the same as the number of the first rectifier output cabinets 310.

[0042] For example, Figure 1 As shown, the power supply system has a first rectifier output cabinet 310, a third rectifier output cabinet 320, a second rectifier output cabinet 410, and a fourth rectifier output cabinet 420. After a first rectifier output cabinet 310 is connected in parallel with a second rectifier output cabinet 410, it is electrically connected to the first electrical input interface 510 of the load 50. After a second rectifier output cabinet 410 is connected in parallel with a fourth rectifier output cabinet 420, it is electrically connected to the second electrical input interface 520 of the load 50. Thus, the first power supply 10 is divided into two paths and then the first electrical input interface 510 and the second electrical input interface 520 of the load 50 are respectively supplied with power, and the second power supply 20 is divided into two paths and then the first electrical input interface 510 and the second electrical input interface 520 of the load 50 are respectively supplied with power.

[0043] At this time, if the supply voltages of the first power supply 10 and the second power supply 20 are the same, and the models of the first rectifier output cabinet 310, the third rectifier output cabinet 320, the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 are the same, the first power supply 10 and the second power supply 20 each carry 50% of the IT load, that is, half of the power supply of the IT load is provided by the first power supply 10, and the other half is provided by the second power supply 20.

[0044] If the supply voltages of the first power supply 10 and the second power supply 20 are different, and / or the models of the first rectifier output cabinet 310, the third rectifier output cabinet 320, the second rectifier output cabinet 410, and the fourth rectifier output cabinet 420 are different, the proportions of the IT loads carried by the first power supply 10 and the second power supply 20 are different. For example, if the first power supply 10 can carry 30% of the IT load, the second power supply 20 can carry 70% of the IT load. For example, if the first power supply 10 can carry 40% of the IT load, the second power supply 20 can carry 60% of the IT load. The IT loads carried by the first power supply 10 and the second power supply 20 can be specifically selected based on actual usage, and the embodiment of the present application does not limit the proportion of the IT loads carried by the two.

[0045] For example, Figure 2 As shown, the power supply system has two first rectifier output cabinets 310, two third rectifier output cabinets 320, two second rectifier output cabinets 410, and two fourth rectifier output cabinets 420. After one of the first rectifier output cabinets 310 is connected in parallel with one of the second rectifier output cabinets 410, it is electrically connected to one of the first electrical input interfaces 510 of the load 50. After another first rectifier output cabinet 310 is connected in parallel with another second rectifier output cabinet 410, it is electrically connected to another first electrical input interface 510 of the load 50. After one of the third rectifier output cabinets 320 is connected in parallel with one of the fourth rectifier output cabinets 420, it is electrically connected to one of the second electrical input interfaces 520 of the load 50. After another third rectifier output cabinet 320 is connected in parallel with another fourth rectifier output cabinet 420, it is electrically connected to another second electrical input interface 520 of the load 50. Thus, the first power supply 10 is divided into four paths to respectively supply power to the first power input interface 510 and the second power input interface 520 of the load 50 , and the second power supply 20 is divided into four paths to respectively supply power to the first power input interface 510 and the second power input interface 520 of the load 50 .

[0046] At this time, if the supply voltages of the first power supply 10 and the second power supply 20 are the same, and the models of the first rectifier output cabinet 310, the third rectifier output cabinet 320, the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 are the same, the first power supply 10 and the second power supply 20 each carry 50% of the IT load.

[0047] If the supply voltages of the first power supply 10 and the second power supply 20 are different, and / or the models of the first rectifier output cabinet 310, the third rectifier output cabinet 320, the second rectifier output cabinet 410, and the fourth rectifier output cabinet 420 are different, the proportions of the IT loads carried by the first power supply 10 and the second power supply 20 are different. For example, if the first power supply 10 can carry 30% of the IT load, the second power supply 20 can carry 70% of the IT load. For example, if the first power supply 10 can carry 40% of the IT load, the second power supply 20 can carry 60% of the IT load. The IT loads carried by the first power supply 10 and the second power supply 20 can be specifically selected based on actual usage, and the embodiment of the present application does not limit the proportion of the IT loads carried by the two.

[0048] When the first power supply 10 fails to supply power, the first rectifier output cabinet 310 and the third rectifier output cabinet 320 will be unable to supply power to the load 50. At this time, the second power supply 20 is electrically connected to the first power input interface 510 and the second power input interface 520 of the load 50 through the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420, so that the power supply system can supply power to the load 50 without interruption. At this time, the second power supply 20 carries 100% of the IT load.

[0049] When the second power supply 20 fails to supply power, the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 will be unable to supply power to the load 50. At this time, the first power supply 10 is electrically connected to the first power input interface 510 and the second power input interface 520 of the load 50 through the first rectifier output cabinet 310 and the third rectifier output cabinet 320, so that the power supply system can supply power to the load 50 without interruption. At this time, the first power supply 10 carries 100% of the IT load.

[0050] When the first power supply 10 or the second power supply 20 is powered off and restored, the rectifier output cabinet can resume operation without performing a mechanical switch action, which can save operation and maintenance time and cost.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments, the first power source 10 is an AC power source. The first rectifier output cabinet 310 and the third rectifier output cabinet 320 are configured to convert AC power into DC power.

[0052] The first rectifier output cabinet 310 and the third rectifier output cabinet 320 can output the output AC power in the form of DC power, thereby supplying DC power to the load 50. The number of the first rectifier output cabinet 310 is the same as the number of the third rectifier output cabinet 320. For example, the first rectifier output cabinet 310 and the third rectifier output cabinet 320 are both set to one. For example, the first rectifier output cabinet 310 and the third rectifier output cabinet 320 are both set to two. The number of the first rectifier output cabinet 310 and the number of the third rectifier output cabinet 320 can be reasonably selected based on the number of the first electrical input interface 510 and the number of the second electrical input interface 520 on the load 50.

[0053] like Figure 1 and Figure 2 As shown, in some embodiments, the power supply system further includes a first incoming cabinet 330. The input end of the first incoming cabinet 330 is electrically connected to the first power source 10, and the output end of the first incoming cabinet 330 is electrically connected to the first rectifier output cabinet 310 and the third rectifier output cabinet 320 respectively.

[0054] The first incoming line cabinet 330 is used to receive power from the first power source 10, and its internal components can play the role of power quality monitoring, safety isolation, power metering, overload protection, etc. The first power source 10 supplies power to the first incoming line cabinet 330, and outputs AC power to the first rectifier output cabinet 310 and the third rectifier output cabinet 320 through the first incoming line cabinet 330. The first rectifier output cabinet 310 and the third rectifier output cabinet 320 convert the AC power into DC power and then supply power to the first electrical input interface 510 and the second electrical input interface 520 of the load 50 respectively, so as to realize the normal operation of the load 50.

[0055] Among them, the first incoming line cabinet 330 and the second incoming line cabinet 430 described below are both collectors that provide electric energy to downstream electrical equipment based on the output cables of generators, transformers, and high-voltage disconnecting switches and lighting equipment. They play the role of receiving and distributing electric energy. Among them, the first incoming line cabinet 330 and the second incoming line cabinet 430 can both include front-stage components, intermediate components, and rear-stage components. The front-stage components usually include cable pipes, cable heads, current transformers, etc. The intermediate components usually include circuit breakers, disconnectors, fuses, and knife switches, etc. The rear-stage components usually include load switches, contactors, and measuring instruments, etc.

[0056] like Figure 1 and Figure 2 As shown, in some embodiments, the power supply system further includes a first power frequency transformer 340. The first power frequency transformer 340 is connected between the first power source 10 and the first incoming line cabinet 330.

[0057] It is understandable that the voltage can be reduced by the first power frequency transformer 340 to ensure the safety of electricity use. For example, the first power supply 10 is a 10kV (kilovolt) AC power supply. The 10kV AC power can be reduced to 380V (volt) AC power (or AC power of other voltage values ​​required by the power supply) after passing through the first power frequency transformer 340, so as to deliver the low-voltage AC power to the first incoming line cabinet 330 to ensure the safety of electricity use. For example, the first power supply 10 is a 35kV AC power supply. The 35kV AC power can be reduced to 380V AC power (or AC power of other voltage values ​​required by the power supply) after passing through the first power frequency transformer 340, so as to deliver the low-voltage AC power to the first incoming line cabinet 330 to ensure the safety of electricity use. For example, the first power source 10 is a 6kV AC power source, and the 6kV AC power can be stepped down to 220V AC power (or AC power of other voltage values ​​required by power supply) after passing through the first power frequency transformer 340, so as to transmit the low-voltage AC power to the first incoming line cabinet 330 to ensure power safety. Among them, the voltage of the first power source 10 and the step-down capacity of the first power frequency transformer 340 can be specifically selected according to actual use conditions, and the embodiment of the present application is not limited.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, the second power source 20 is an AC power source. The second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 are configured to convert AC power into DC power.

[0059] The second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 can output the output AC power in the form of DC power, thereby supplying DC power to the load 50. The number of the second rectifier output cabinet 410 is the same as the number of the fourth rectifier output cabinet 420. For example, the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 are both set to one. For example, the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 are both set to two. The number of the second rectifier output cabinet 410 and the number of the fourth rectifier output cabinet 420 can be reasonably selected based on the number of the first electrical input interface 510 and the number of the second electrical input interface 520 on the load 50.

[0060] like Figure 1 and Figure 2 As shown, in some embodiments, the power supply system further includes a second incoming cabinet 430. The input end of the second incoming cabinet 430 is electrically connected to the second power source 20, and the output end of the second incoming cabinet 430 is electrically connected to the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 respectively.

[0061] The second incoming line cabinet 430 is used to receive power from the second power source 20, and its internal components can play the role of power quality monitoring, safety isolation, power metering, overload protection, etc. The second power source 20 supplies power to the second incoming line cabinet 430, and outputs AC power to the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 through the second incoming line cabinet 430. The second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 convert the AC power into DC power and then supply power to the first electrical input interface 510 and the second electrical input interface 520 of the load 50 respectively, so as to realize the normal operation of the load 50.

[0062] like Figure 1 and Figure 2 As shown, in some embodiments, the power supply system further includes a second power frequency transformer 440. The second power frequency transformer 440 is connected between the second power source 20 and the second incoming line cabinet 430.

[0063] It is understandable that the voltage can be reduced by the second power frequency transformer 440 to ensure the safety of electricity use. For example, the second power supply 20 is a 10kV AC power supply. The 10kV AC power can be reduced to 380V AC power (or AC power of other voltage values ​​required by the power supply) after passing through the second power frequency transformer 440, so as to deliver the low-voltage AC power to the second incoming line cabinet 430 to ensure the safety of electricity use. For example, the second power supply 20 is a 35kV AC power supply. The 35kV AC power can be reduced to 380V AC power (or AC power of other voltage values ​​required by the power supply) after passing through the second power frequency transformer 440, so as to deliver the low-voltage AC power to the second incoming line cabinet 430 to ensure the safety of electricity use. For example, the second power supply 20 is a 6kV AC power supply, and the 6kV AC power can be stepped down to 220V AC power (or AC power of other voltage values ​​required by power supply) after passing through the second power frequency transformer 440, so as to transmit the low-voltage AC power to the second incoming line cabinet 430 to ensure power safety. Among them, the voltage of the second power supply 20 and the step-down capacity of the second power frequency transformer 440 can be specifically selected according to actual use conditions, and the embodiment of the present application is not limited thereto.

[0064] like Figure 2As shown, two first rectifier output cabinets 310, two second rectifier output cabinets 410, two third rectifier output cabinets 320 and two fourth rectifier output cabinets 420 are set as an example. The high-voltage AC supplied by the first power source 10 is stepped down to low-voltage AC by the first power frequency transformer 340, and then enters the first incoming line cabinet 330. The first incoming line cabinet 330 divides the low-voltage AC into four paths to be respectively transmitted to the two first rectifier output cabinets 310 and the two third rectifier output cabinets 320. After the two first rectifier output cabinets 310 and the two third rectifier output cabinets 320 convert the low-voltage AC into low-voltage DC, they supply power to the first electrical input interface 510 and the second electrical input interface 520 of the load 50. Similarly, the high-voltage AC supplied by the second power source 20 is stepped down to low-voltage AC by the second power frequency transformer 440, and then enters the second incoming line cabinet 430. The second incoming line cabinet 430 divides the low-voltage AC into four paths for transmission to the two second rectifier output cabinets 410 and the two fourth rectifier output cabinets 420. After the two second rectifier output cabinets 410 and the two fourth rectifier output cabinets 420 convert the low-voltage AC into low-voltage DC, they supply power to the first electrical input interface 510 and the second electrical input interface 520 of the load 50.

[0065] The first rectifier output cabinet 310, the second rectifier output cabinet 410, the third rectifier output cabinet 320 and the fourth rectifier output cabinet 420 all have current sharing control, so that the first power supply 10 and the second power supply 20 each carry 50% of the IT load during normal power supply.

[0066] The embodiment of the present application also provides a data center. The data center includes a power supply system and a load 50 as in the above embodiment, and the load 50 has a first electrical input interface 510 and a second electrical input interface 520. The first parallel end is electrically connected to the first electrical input interface 510, and the second parallel end is electrically connected to the second electrical input interface 520.

[0067] In this embodiment, the current of the first power source 10 is output in two ways through the first rectifier output cabinet 310 and the third rectifier output cabinet 320, so that the first power source 10 can simultaneously supply power to the first power input interface 510 and the second power input interface 520 of the load 50. The current of the second power source 20 is output in two ways through the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420, so that the second power source 20 can simultaneously supply power to the first power input interface 510 and the second power input interface 520 of the load 50. When one of the power supplies stops supplying power due to a fault, for example, when the second power supply stops supplying power due to a fault, the second rectifier output cabinet 410 and the fourth rectifier output cabinet 420 cannot supply power to the loads corresponding to the first electrical input interface 510 and the second electrical input interface 520 respectively, and the other power supply can also continuously supply power to the load 50 through the first electrical input interface 510 and the second electrical input interface 520 at the same time, that is, currently only the first power supply supplies power to the loads corresponding to the first electrical input interface 510 and the second electrical input interface 520 through the first rectifier output cabinet 310 and the third rectifier output cabinet 320, ensuring that the load 50 does not experience power interruption, and preventing the load 50 from restarting or shutting down due to power failure. At the same time, the use of the mother coupling cabinet is eliminated, which can reduce the floor space and reduce costs.
