It is interrupted regulated power supply system, uses UPS single supply when design and power and mains-supplied is for mode, need to carry out long-term
Reliability test, it is provided that the long-term uninterrupted power supply of emphasis critical position, many places, to meet the use requirement of system, its peace
Full stable operation is the guarantee of whole pilot system safety.
And in factory's actual production, UPS is not the most reliable, it is also desirable to carry out regularly maintenance work, also can
Break down shutdown phenomenon, and such as ups power controls power pack and burns out suddenly, and at this moment ups power power supply mode cannot be just
Often power supply, whole DCS control system is only by mains-supplied；If it addition, electrical network fluctuates, can be to whole process units band
Carry out potential safety hazard seriously, so that ups power device loses the function ensureing that process units is properly functioning.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide the redundancy backup electricity of a kind of ups power system
Road, this circuit has rational stand-by power supply mode, it is possible to during UPS breaks down, it is achieved the uninterrupted confession of electric power
Should.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:
The redundant backup circuit of a kind of ups power system, it it is critical only that: includes host computer system, at least one standby host system
System and main power source supply line that respectively host computer system and reserve system are powered, stand-by power supply supply line, described standby host
The outlet line of system is connected with the static by-pass incoming line of described host computer system, and the outlet line of described host computer system connects
To exporting bus, it is provided with between static by-pass incoming line and the outlet line of reserve system of described host computer system automatically
Switching by-pass switch.
In this redundancy backup circuit, the output voltage of UPS reserve system is connected to the bypass input of UPS host computer system
End.When normally working, UPS host computer system undertakes whole bearing power. automatically switch to side when UPS host computer system breaks down
Line state, UPS reserve system continues as load supplying by the bypass channel of UPS host computer system；When commercial power interruption, at UPS
Duty in battery discharge.Owing to UPS host computer system undertakes whole bearing power, so its accumulator first discharges into termination
Voltage, then automatic switchover by-pass switch Guan Bi i.e. automatically switches to bypass state, UPS reserve system be that load supplies
Electricity, until the battery discharging of reserve system is to final voltage.It is achieved thereby that UPS host computer system and reserve system, standby host system
System and civil power answer Phase-Locked Synchronous.
Further, described host computer system is provided with manual maintenance bypass switch in the bypass of back-up system.
By described manual maintenance bypass switch, it is easy to power-off when host computer system breaks down with back-up system and ties up
Repair.
Further, the main road supply line of described host computer system and back-up system is provided with main road to power open circuit
Device, described host computer system and the outlet line of back-up system are provided with output connection chopper.
Further, described host computer system and back-up system can be H015K31 or H020K310 silent oscillation UPS.
Remarkable result of the present utility model is: reliable, technology is simple；Motility is high, is not limited by brand；Letter is installed
Single, it is not necessary to additionally to debug；Do not increase extra auxiliary circuit, do not increase extra acquisition cost；When host computer system goes wrong, standby host
System full-load run；And N+1 Hot Spare can be made, can dilatation by stages；Eliminate potential safety hazard；Ensure the properly functioning of production.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model and operation principle are described in further detail.
As it is shown in figure 1, the redundant backup circuit of a kind of ups power system, including host computer system, reserve system and difference
The main power source supply line powered for host computer system and reserve system, stand-by power supply supply line, described host computer system and standby host
System all includes commutator, inverter, isolating transformer and accumulator battery, and the outlet line of described reserve system is with described
The static by-pass incoming line of host computer system is connected, and the outlet line of described host computer system is connected to export bus, described master
It is provided with automatic switchover by-pass switch between static by-pass incoming line and the outlet line of reserve system of machine system.
Open from figure 1 it appears that be provided with manual maintenance bypass in described host computer system and the bypass of back-up system
Close.
From figure 1 it appears that be provided with main road confession in described host computer system and the main road supply line of back-up system
Electrical circuit breakers, described host computer system and the outlet line of back-up system are provided with output connection chopper.
Described host computer system and back-up system can be H015K31 or H020K310 silent oscillation UPS, are preferably in this example
H020K310 silent oscillation UPS.
The operation principle of this circuit is:
When normally working, UPS host computer system undertakes whole bearing power；
When UPS host computer system breaks down, described automatic switchover by-pass switch closes, i.e. UPS host computer system is cut automatically
Changing to bypass condition, UPS reserve system continues as load supplying by the bypass channel of UPS host computer system；
When commercial power interruption, UPS is in the duty of battery discharge: all load merit owing to UPS host computer system undertakes
Rate, so its accumulator first discharges into final voltage, then automatic switchover by-pass switch Guan Bi i.e. automatically switches to bypass
State, is load supplying by UPS reserve system, until the battery discharging of reserve system is to final voltage.
By said process, this circuit realiration UPS host computer system and reserve system, reserve system and civil power should phase-locked with
Step.
