Compared with prior art, the beneficial effect that the utility model has is:
The control cubicle of this ups power, has possessed the repertoire of UPS control cubicle in prior art, can when main electricity breaks down, automatically switch to the power supply that ups power is DCS dispatch control system.Simultaneously, once ups power, break down and need to change, by the bypass power supply loop and the outside maintenance bypass that arrange in control circuit, without power-off, can change ups power, guarantee the normal work that DCS and other can not power cutoff devices, guaranteed DCS continuing to monitor field conditions.Due to without system is carried out to power-off, therefore avoided restarting of equipment component, the equipment of having saved is restarted the wasted time, has avoided the production that device powers down is brought to incur loss through delay simultaneously.
Accompanying drawing explanation
Fig. 1 is the control cubicle control circuit electrical schematic diagram of ups power.
Embodiment
Fig. 1 is most preferred embodiment of the present utility model, below in conjunction with 1 pair of the utility model of accompanying drawing, is described further.
A kind of control cubicle of ups power, comprise cabinet and be fixed on the control circuit in cabinet, as shown in Figure 1, the control circuit in the control cubicle of ups power comprises: static switch U1, rectifier U2, inverter U3 and ups power U4 and be connected to a plurality of switches in control circuit.
400VAC main power source is connected with the input of rectifier U2 after tandem tap K1, normally opened contact SWIN successively, the input of the output connection inverter U3 of rectifier U2, the output of the inverter U3 normally-closed contact SWOUT that connects successively.After K switch 4, connect DCS and other loads.After ups power U4 tandem tap QF1, be connected in parallel between rectifier U2 and inverter U3.
400VAC bypass supply is one end of paralleling switch K2 ~ K3 simultaneously, and the other end of K switch 3 is connected with DCS and other loads; The other end while normally opened contact SWMB in parallel of K switch 2 and one end of normally-closed contact SWBY.The other end of normally opened contact SWMB is connected in parallel between above-mentioned normally-closed contact SWOUT and K switch 4; After the other end tandem static switch U1 of normally-closed contact SWBY, be connected in parallel between the output and normally-closed contact SWOUT of above-mentioned inverter U3.
Specific works process and principle are as follows:
When normal work, K switch 1, K switch 2 and K switch 4 closures, normally opened contact SWIN, switch QF1 are closed simultaneously, and now 400VAC main power source is powered to DCS and other loads, simultaneously for ups power U4 charges.400VAC main power source through K switch 1, that closed normally opened contact SWIN is carried in rectifier U2 is upper, through rectifier U2 by alternating current whole be direct current.By rectifier U2 output ground direct current, enter inverter U3, from inverter U3, direct current is become to the alternating current that DCS and other loads can be used, inverter U3 output ground alternating current is loaded in DCS and other loads through normally-closed contact SWOUT, K switch 4.
When 400VAC main power source breaks down, switch QF1 connects, and by ups power U4, is that DCS and other loads are powered.Now, ups power U4 output ground alternating current enters in inverter U3, from inverter U3, direct current is become to the alternating current that DCS and other loads can be used.
When ups power U4 breaks down need to change time, now static switch U1 action, normally opened contact SWMB is closed, and by the access of 400VAC bypass supply, now 400VAC bypass supply is DCS and other load supplyings through K switch 4.Then turn on-switch K3, and K switch 1, K switch 2 and K switch 4 are disconnected, the now bribery of 400VAC bypass supply through K3 place is that DCS and other loads are powered, ups power U4 departs from completely from circuit simultaneously, convenient ups power U4 is changed.After replacing completes, by K switch 1, K switch 2 and K switch 4 closures, K switch 3 is connected, recovered normal operating conditions.
In the control cubicle of this ups power, K switch 1 ~ K4 adopts hand push button switch to realize, and also can adopt other forms of switch to replace, and also can realize by contactor, and now K switch 1 ~ K4 can replace with the contact in contactor.
The above, it is only preferred embodiment of the present utility model, be not the utility model to be done to the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection range of technical solutions of the utility model.
