Description
Technical field
This utility model relates to a kind of UPS power supply unit, particularly relates to a kind of UPS on-line maintenance device.
Background technology
At present, DCS on enterprise's production line and PLC control system quantity progressively increase, but most electric power system is a configuration ups power all only, whole control system is all only powered by separate unit UPS, wherein a part of UPS runs for many years continuously, be no matter UPS or storage battery all beyond its design service life, the risk broken down significantly raises.Workshop air is second-rate in addition, all comparatively serious to the corrosion of UPS, 24V power supply and supply line, so electric power system failure rate is very high, if there is system shutdown, can cause very large hidden danger within a very long time whole production system.Because monitoring and control site technique parameter, there is serious accident in the serious site technique equipment that will cause.
Because DCS and PLC control system require higher to electric power system, when line voltage extremely unstable, current DCS and PLC control system are powered by line type UPS by being system power supply after inverter inversion.The factors of instability have the factor such as local broken string of power failure, inside plants a certain road live wire.Once UPS breaks down will automatically switch to auto by pass, be equivalent to by civil power directly for DCS powers, and now UPS cannot throw off maintenance from production system.And to be powered to DCS control system by the civil power of spread of voltage for a long time control device can be caused to damage, the safe and stable operation of serious threat DCS control system and production system.
Utility model content
The utility model overcomes in prior art, and UPS not timing is overhauled, and needs the problem isolated from circuit, the UPS on-line maintenance device providing a kind of structure simple, easy to use.
Technical solution of the present utility model is, there is provided a kind of UPS on-line maintenance device with following structure: containing power supply bypass changeover switch, UPS current supply circuit switching device shifter, described power supply bypass changeover switch and UPS current supply circuit switching device shifter are and tie, its end connects DCS load, and the live wire of described power supply bypass changeover switch and UPS current supply circuit switching device shifter head end is connected three live wires of three phase mains by phase diverter switch.
Described phase diverter switch is rotary four driving switch, and wherein three gears connect three live wires of three phase mains respectively, and a gear is neutral position.
Described UPS current supply circuit switching device shifter contains UPS inlet wire control switch, UPS and UPS goes out line control switch, and it is connected successively, goes out line control switch and connects DCS load.
Described power supply bypass changeover switch, UPS inlet wire control switch and UPS go out line control switch and are air switch.
Compared with prior art, the utility model UPS on-line maintenance device has the following advantages: on-line maintenance apparatus design will solve DCS and PLC control system and to power when UPS breaks down the normal operation of not influential system, and will by increasing external by-pass switch to UPS, under the precondition not affecting production and control system stable operation, fault UPS is kept apart from system, realize carrying out Maintenance and Repair to UPS when not affecting production system.
Connected three live wires of three phase mains in end of incoming cables by phase diverter switch, when the electrical network in subrange occurs breaking mutually, after the signal obtaining UPS startup operating state, can be transformed into by hand in other normal phase voltages.
By a series of measure, achieve the safety and stability long-term operation of control system, ensure the high load capacity steady production of Chemical Manufacture.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model UPS on-line maintenance device.
Embodiment
During accompanying drawing illustrates, label 1 is phase diverter switch, and 2 is power supply bypass changeover switches, and 3 is UPS inlet wire control switchs, and 4 is that UPS goes out line control switch.
Below in conjunction with the drawings and specific embodiments, the utility model UPS on-line maintenance device is described further: as shown in the figure, containing power supply bypass changeover switch in the present embodiment, UPS current supply circuit switching device shifter, described power supply bypass changeover switch and UPS current supply circuit switching device shifter are and tie, its end connects DCS load, and the live wire of described power supply bypass changeover switch and UPS current supply circuit switching device shifter head end is connected three live wires of three phase mains by phase diverter switch.
Described phase diverter switch is rotary four driving switch, and wherein three gears connect three live wires of three phase mains respectively, and a gear is neutral position.
Described UPS current supply circuit switching device shifter contains UPS inlet wire control switch, UPS and UPS goes out line control switch, and it is connected successively, goes out line control switch and connects DCS load.
Described power supply bypass changeover switch, UPS inlet wire control switch and UPS go out line control switch and are air switch.
Wherein UPS on-line maintenance device input coefficient step: 1, check that first wiring puts ON state power supply bypass changeover switch 2 after normal, at this moment by civil power by external bypass directly to DCS load supplying.2, next UPS inlet wire control switch is put 3 and is set to ON state, and at this moment UPS powers on and understands auto by pass pattern, direct output AC civil power.3, power supply bypass changeover switch 2 is put OFF state, at this moment DCS load still can be powered by UPS auto by pass.Finally UPS being started by auto by pass pattern be inversion is DCS load supplying.
UPS excises step from system: 1, from system, should first check each position of the switch before excision, and when power supply bypass changeover switch 2 is OFF state, UPS inlet wire control switch 3 is ON state, and UPS goes out line control switch 4 for ON state.2, automatically can be switched to auto by pass during UPS fault is load supplying, now if desired UPS is excised from system, first should check and judge whether UPS is switched to auto by pass, if UPS status indicator lamp instruction bypass condition, can determine that UPS has been switched to auto by pass state.3, now power supply bypass changeover switch 2 can be got to ON state again.4, after ON state got to by bypass changeover switch 2 of powering, first UPS being gone out line control switch 4 and get to OFF state, then UPS inlet wire control switch 3 is got to OFF state, has been now DCS load supplying by complete for UPS release systems civil power.
