Description
Technical field
The present invention relates to electric supply configuration technology field more particularly to a kind of UPS and machine segmentation power supply energy conservation configuration systems
System.
Background technique
UPS (Uninterruptible Power System/Uninterruptible Power Supply), i.e., not between
Power-off source, effect are that, when mains input is normal, UPS rectifies alternating current into direct current, then again that direct current is inverse
Become to stablize the alternating current of free from admixture, powering load.During UPS powering load, load is not to be chronically at completely
Load situation, but according to actual needs in the situation changed.The delivery efficiency and institute's bringing onto load capacity of UPS is nonlinear dependence
System, relation curve can be found in attached drawing 1, it can be seen from the figure that efficiency sharply declines when UPS band load rate is less than 30%.UPS forbids
Long-time overload operation.
Currently, UPS is all made of redundant configuration to ensure that load obtains continuing reliably powering, 2 UPS and load it is superfluous
Remaining configuration connection system mainly include the following types: (can refer to DL/T1074-2007 electric power direct current with exchange it is integrated uninterrupted
Power-supply device)
1, series connection standby redundancy UPS configuration: (configuration diagram is shown in attached drawing 2)
The standby redundancy UPS that connects is configured, and is a UPS as power supply main computer powering load, in addition a UPS conduct
Guest machine, bypass input of the output of guest machine UPS as host UPS.Under normal circumstances, main computer bringing onto load is run, spare
Machine, which is in, waits working condition, and it is zero that band, which carries,.When main computer UPS failure, it is rapidly switched to the operation of guest machine UPS bringing onto load.
Series connection standby redundancy UPS configuration is primarily present following disadvantage:
Spare UPS captain's phase is in standby, and spare machine battery is thus also chronically at floating charge electricity condition, seriously affects
Battery life.
When load is greater than the output capacity of main computer UPS, UPS can issue alarm signal, although the standby operation of guest machine
Band load rate is zero, and user can operate normally after must also cutting off extra load.
2, the using and the reserved parallel connection standby redundancy UPS is configured: (configuration diagram is shown in attached drawing 3)
The using and the reserved parallel connection standby redundancy UPS configuration is two-way electricity of the output respectively as twin-power switch of two UPS
Source input, then pass through the output powering load of twin-power switch, exporting to the UPS of dual power supply main power circuit is main computer,
Exporting to the UPS of dual power supply back-up circuit is guest machine.Under normal circumstances, main computer is run by twin-power switch bringing onto load,
Guest machine, which is in, waits working condition, and it is zero that band, which carries,.When main computer UPS failure, pass through Twin-power swich to guest machine
The operation of UPS bringing onto load.
The using and the reserved parallel connection standby redundancy UPS configuration is primarily present following disadvantage:
Spare UPS captain's phase is in standby, and spare machine battery is thus also chronically at floating charge electricity condition, seriously affects
Battery life.
When load is greater than the output capacity of main computer UPS, UPS can issue alarm signal, although the standby operation of guest machine
Band load rate is zero, and user can operate normally after must also cutting off extra load.
3, two each bands, one section of mutual backup redundancy UPS configuration: (configuration diagram is shown in attached drawing 4)
Two each bands, one section of mutual backup redundancy UPS configuration, is that will load to be divided into two parts, respectively by two sections of buses to negative
It carries and power supply is provided.The output of each UPS in two UPS is respectively as the main power source input of 1 twin-power switch and another
The backup power source input of one dual power supply.Two twin-power switch, one section of bus of each band gives this section of load supplying.Under normal circumstances,
Every UPS passes through this section of twin-power switch to this section of load supplying, when there is a UPS to break down, the end failure UPS it is double
Power switch is rapidly switched in the output of another UPS, and another UPS passes through two twin-power switch and drive two sections of loads
Operation.
Two each bands, one section of mutual backup redundancy UPS configuration is primarily present following disadvantage:
When two sections of loads are amounted to no more than separate unit UPS output capacity, when every section of load is less than separate unit UPS output capacity
50% and lower, as soon as being still each band Duan Yunhang of two UPS, the efficiency of UPS almost drops to 60% and less.
4,1+1 parallel redundancy UPS is configured: (configuration diagram is shown in attached drawing 5)
1+1 parallel redundancy UPS configuration is two UPS by parallel function while powering load, and every UPS undertakes
50% load capacity.Under normal circumstances, two UPS powering load simultaneously, when there is a UPS to break down, an other UPS
To whole load supplyings.
1+1 parallel redundancy UPS configuration is primarily present following disadvantage:
When load capacity be less than separate unit UPS output capacity 50% and it is lower when, be still that undertake half negative by two UPS
Carrying capacity is run simultaneously, and the efficiency of UPS just almost drops to 60% and less.

Point J1-2 junction closure, contactor CJ3 coil obtain electric, CJ3 contactor closure, and CJ3 assists normally closed point CJ3-1 disconnection, contactor
CJ2 coil losing electricity, CJ2 contactor disconnect, and after CJ3 contactor closure, CJ3 main contact is by AC1 and two section of load AC2 of one section of load
It connects；CJ2 contactor disconnects, and is disconnected the power supply output loop of UPS2, then AC1 and two section of load AC2 of one section of load is equal
It is powered by UPS1；When load current is greater than separate unit UPS output capacity 95%, the relay J1 coil in current monitoring system is obtained
Electricity closure, J1 assist normally closed point J1-1 contact to disconnect, and contactor CJ3 coil losing electricity, CJ3 contactor disconnects, and CJ3 assists normally closed point
CJ3-1 closure, contactor CJ2 coil obtain it is electric, CJ2 contactor closure, CJ3 contactor disconnect after, CJ3 main contact by one section load
AC1 and two section of load AC2 is disconnected, and after CJ2 contactor closure, CJ2 is to two sections of load AC2 power supplies, and contactor CJ1 is to one section of load
AC1 power supply.
