Description
Technical field
The present invention relates to a kind of UPS connection circuit, especially relate to a kind of UPS connection circuit for HYCO factory.
Background technology
For improving power supply reliability, HYCO (purified synthesis gas is separated carbon monoxide processed and hydrogen) DCS in factory (distribute control) system general is at present all powered by UPS (ac uninterrupted power supply), the ups power mode of connection generally adopts modular being connected in series, i.e. power supply, UPS, static bypass switch, DCS.This mode of connection, when UPS internal component fault, generally can automatically switch to static bypass switch work---automatically excise rectification, inversion element.At this moment, DCS system will lose the protection of UPS, once electric power system voltage fluctuation (external power source circuit fault causes), will directly cause process units system shutdown, cause heavy economic losses and affect the continuous production of upstream and downstream enterprise.
Summary of the invention
Object of the present invention is exactly provide a kind of applied widely, UPS connection circuit for HYCO factory that power supply reliability is high to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of UPS connection circuit for HYCO factory, comprise conventional power supply, stand-by power supply, double power automatic switching device, first contactor, second contactor, one UPS, 2nd UPS and load, described double power automatic switching device connects conventional power supply respectively, stand-by power supply, the coil of the first contactor and the coil of the second contactor, described conventional power supply connects a UPS and the 2nd UPS respectively by the normally opened contact of the first contactor, described stand-by power supply connects a UPS and the 2nd UPS respectively by the normally opened contact of the second contactor, a described UPS is all connected with load with the 2nd UPS,
Double power automatic switching device detects the state of conventional power supply and stand-by power supply in real time, and send signal according to the state detected to the coil of the first contactor and/or the second contactor, the coil of the first contactor or the second contactor obtain electric after corresponding normally opened contact is closed, one UPS and/or the 2nd UPS works, and powers to the load.
A described UPS and the mains side of the 2nd UPS are all connected with isolation knife and melt group, and load-side is all connected with air circuit.
A described UPS and the 2nd UPS is capacity and the identical UPS of technical parameter.
Compared with prior art, the present invention has the following advantages:
1, applied widely, two UPS adopting any brand technical parameter identical by the technical program wiring, can be applicable to the important load of multiple different capabilities requirement.
2, power supply reliability increases substantially, and by Dual-power automatic switching, power supply reliability is doubled, and being automatically switched by double-H groove weld PS is doubled power supply reliability again.Especially the on-line automatic handoff functionality of double-H groove weld PS, thoroughly solves the hidden danger due to UPS internal component fault reduction DCS power supply reliability.Meet the requirement of HYCO device long period safe and stable operation completely.
3, the air circuit that the cutter of ups power side installing melts group and load side had both played the protective effect to circuit, again can when one group of UPS inner member fault, was reliably isolated by the UPS of fault and carried out overhauling and do not affect downstream load and normally run.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed execution mode and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, a kind of UPS connection circuit for HYCO factory, comprise conventional power supply 1, stand-by power supply 2, double power automatic switching device (AUTO TRANSFER) 3, first contactor, second contactor, one UPS4, 2nd UPS5 and load 6, described double power automatic switching device 3 connects conventional power supply 1 respectively, stand-by power supply 2, the coil 7 of the first contactor and the coil 8 of the second contactor, described conventional power supply 1 connects a UPS4 and the 2nd UPS5 respectively by the normally opened contact 9 of the first contactor, described stand-by power supply 2 connects a UPS4 and the 2nd UPS5 respectively by the normally opened contact 10 of the second contactor, a described UPS4 is all connected with load 6 with the 2nd UPS5.Double power automatic switching device 3 detects the state of conventional power supply 1 and stand-by power supply 2 in real time, and send signal according to the state detected to the coil of the first contactor and/or the second contactor, the coil of the first contactor or the second contactor obtain electric after corresponding normally opened contact is closed, one UPS4 and/or the 2nd UPS5 works, and powers to the load.
In the present embodiment, load is DCS system.Double-H groove weld PS the DCS supply power mode of tie drastically increase the reliability of power supply, and every platform UPS can meet the requirement of DCS to power supply capacity.
Commonly use power supply 1, stand-by power supply 2 respectively by different bussed supply, when after conventional power failure power-off, alternate power autocast, thus ensure the continuity that UPS powers.
One UPS4 and the 2nd UPS5 is the structure of capacity and technical parameter identical UPS, UPS is existing structure, comprising storage battery.Normal operating conditions can be set to one and run for whole load, and another is online for subsequent use; Or two are all run each confession 50% load.Every platform UPS is furnished with batteries according to load capacity, and under the extreme case that two-way power supply all disconnects, still can ensure the continuous power supply to particular importance load, power-on time is determined by battery capacity, is generally set to 2 hours according to load character.The mains side of the one UPS4 and the 2nd UPS5 is all connected with isolation knife and melts group 11; load-side is all connected with air circuit 12; both played the protective effect to circuit, when one group of UPS inner member fault, the UPS of fault reliably can have been isolated carry out overhauling and do not affect downstream load and normally run again.
