The intelligent timing device BZ is connected to the inverter UI, and power supply is obtained from inverter.
The display SHOW is connected to the inverter UI, and power supply is obtained from inverter.
Further, it is interlocked relationship that first contactor KM1, which states second contactor KM2,.
Further, under civil power normal operation, first contactor KM1 adhesives, second contactor KM2 disconnects, this When inverter UI do not work;In utility power failure, second contactor KM2 adhesives, first contactor KM1 disconnects, inverter UI starts working, and the direct current in battery is reverse into alternating current through inverter UI.
Further, intelligent timing utensil, which has, puts into the statistics recording feature of emergency operating number of times to inverter, every time should The timing recording function of anxious time, the cumulative timing recording function of crash time, and intelligent timing device screen display can be passed through.
Further, charger U, inverter UI, intelligent timing device BZ, display SHOW have RS485 interfaces, charger U, inverter UI, intelligent timing device BZ are connected to display SHOW by order wire respectively, transmit a signal to display SHOW. By display SHOW, the information that charger U, inverter UI, intelligent timing device BZ are uploaded can be monitored in real time.
Beneficial effects of the present invention:The present invention provides a kind of emergency power system with intelligent timing function, by Intelligent timing device is set in emergency power supply, and transferred data on emergency power supply display, user can be emergent with real-time monitored Emergent number of times, the time of each emergency operating and the emergent total time of power supply, the use shape of emergency power supply is preferably judged with this Condition.
Brief description of the drawings
Accompanying drawing is used for providing a further understanding of the present invention, and constitutes a part for specification, the reality with the present invention Applying example is used to explain the present invention together, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is a kind of emergency power system schematic diagram with intelligent timing function that the present invention is provided.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, following examples, to present invention progress It is further to describe in detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, this is not limited Invention.
As shown in figure 1, a kind of emergency power system with intelligent timing function, including civil power AC, input breaker QFA, charger U, battery GB, inverter UI, isolating transformer T, intelligent timing device BZ, display SHOW, first contactor KM1, second contactor KM2, output circuit breaker Q FB.
The civil power AC is connected to input circuit breaker Q FA, and the input circuit breaker Q FA outputs are divided into two-way, connected all the way To first contactor KM1 one end, another road is connected with the input of the charger U.
