Background technology
Modern society; to some equipment; the continuity reliability of operation of such as server, Medical Devices requires more and more higher; no longer meet UPS only as being function that information data emergency backup provides the short time to power when alternating current input power supplying exception or power-off; and to AC power reply abnormal failure, provide the ability of continued power to have higher requirement.For this increasing standby generator sets, be about to lose power supply capacity or lost power supply capacity once main Blast Furnace Top Gas Recovery Turbine Unit (TRT) breaks down, start auxiliary generation device immediately, continue to power to equipment, and in this process, the operation of requirement equipment is not subject to the impact of external ac power source switching, the continuity of guarantee information data run.
Summary of the invention
In order to overcome existing technical barrier, the utility model provides a kind of alternating current uninterrupted switching system based on UPS, once the main Blast Furnace Top Gas Recovery Turbine Unit (TRT) of equipment use breaks down lose power supply capacity, starts auxiliary generation device immediately, continues to power to equipment.In this process, the operation of equipment is not by the impact that external ac power source switches, and the continuity of information data work for the treatment of is guaranteed.
Based on an alternating current uninterrupted switching system of UPS, comprise main road AC-powered system, bypass AC-powered system, contactor, uninterrupted power supply.Contactor comprises the first switch, second switch, the first switch normally opened contact, the first switch normally-closed contact, second switch normally opened contact, second switch normally-closed contact, actuation coil; The live wire of main road AC-powered system is connected with the first switch normally opened contact and actuation coil one end respectively, and zero line is connected with second switch normally opened contact and the actuation coil other end respectively; The live wire of bypass AC-powered system is connected with the first switch normally-closed contact, and zero line is connected with second switch normally-closed contact; First switch switches between the first switch normally opened contact, the first switch normally-closed contact; Second switch switches between second switch normally opened contact, second switch normally-closed contact; First switch and second switch are connected with the input of uninterrupted power supply respectively, and the output of uninterrupted power supply is connected with testing equipment.
The utility model compared with prior art, has the following advantages: (1) achieves the steady switching of the different power supply of two-way, and the continuous reliability of operation of equipment is improved; (2) be that alternating current switches and spacer assembly with contactor, the fail safe of system strengthens.
Below in conjunction with Figure of description, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is that alternating current does not cut off switched system operation principle schematic diagram.
Embodiment
Based on an alternating current uninterrupted switching system of UPS, be made up of main road AC-powered system 1, bypass AC-powered system 2, contactor 3, uninterrupted power supply (UPS) 4, the output of uninterrupted power supply 4 is connected with testing equipment 5.Main road AC-powered system 1, bypass AC-powered system 2 provide electric energy for testing equipment 5; Contactor 3 is main road AC-powered system 1, bypass AC-powered system 2 provides alternating current to isolate and handoff functionality.In the of short duration process that master 1, bypass 2 alternating current switch, uninterrupted power supply (UPS) 4 is responsible for the use electronic compensating providing testing equipment 5, ensures the smooth transition of equipment between the normal operation and two groups of AC power of alternating current switching slot.
Contactor 3 comprises the first switch 10, second switch 11, first switch normally opened contact 13, first switch normally-closed contact 14, second switch normally opened contact 15, second switch normally-closed contact 16, actuation coil 12.
System connected mode is as follows:
The actuation coil 12 of contactor 3 inside is controlled by main road AC power;
The live wire 6 of main road AC-powered system 1 and zero line 8 receive the first switch normally opened contact 13 of the first switch 10 in contactor 3 and the second switch normally opened contact 15 of second switch 11 respectively; The live wire 7 of bypass ac power supply system and zero line 9 receive the first switch normally-closed contact 14 of the first switch 10 and the second switch normally-closed contact 16 of second switch 11 respectively;
The power input of the first switch 10 of contactor 3 inside, common access uninterrupted power supply (UPS) 4 of second switch 11;
The power output end of uninterrupted power supply (UPS) 4 is powered to testing equipment 5.
The mode of the uninterrupted system cloud gray model of alternating current is as follows:
When main road AC-powered system 1 is powered, contactor 3 internal actions coil 12 powers on, the current collector of the first switch 10 moves on to the first switch normally-closed contact 14 from the first switch normally opened contact 13, and the current collector of same second switch 11 also moves on to normally-closed contact 16 from normally opened contact 15.The power supply that now switch common point outputs to uninterrupted power supply (UPS) 4 is the power supply of main road AC-powered system 1, is also the power supply of the current use of testing equipment 5;
When after the power-off of main road AC-powered system 1, the power-off of contactor internal actions coil 12, the current collector of the first switch and second switch gets back to original position, the power supply that switch common point outputs to uninterrupted power supply (UPS) 4 is the power supply of bypass AC-powered system 2 supply, is also the power supply of the current use of testing equipment 5;
When alternating current switching generation power failure gap occurs in contactor 3 inside, completed by uninterrupted power supply (UPS) 4 for electronic compensating;
After contactor 3 internal electric source has switched, realized the steady handing-over of power supply by the transfer characteristic of UPS4 inside " alternating current → rectification → inverter ".
