Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below by detailed description of the invention, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of on line type UPS power-supply system, including maintenance supplying channels, bypass power supply passage, UPS supplying channels, power change-over switch that double-cricuit supply is connected with described double-cricuit supply and the first A.C. contactor KM1 of being connected with described power change-over switch;Preferably, described double-cricuit supply includes a road mains supply and a road stand-by power supply, described stand-by power supply is alternating current generator, when described mains supply breaks down, described alternating current generator can also be passed through and continue powering load, thus ensureing this continual powering load of on line type UPS power-supply system.
Described maintenance supplying channels is serially connected with service switch, described bypass power supply passage is serially connected with by-pass switch;The normally opened contact KM11 of described first A.C. contactor KM1 concatenates described service switch and constitutes described maintenance supplying channels;The normally-closed contact KM12 of described first A.C. contactor KM1 concatenates described by-pass switch and constitutes described bypass power supply passage;The normally-closed contact KM12 of described first A.C. contactor KM1 is connected with the input of described UPS supplying channels;Described maintenance supplying channels, described bypass power supply passage are all connected with load with described UPS supplying channels.When the normally-closed contact of described first A.C. contactor KM1 close, normally opened contact disconnect time, described double-cricuit supply pass through described UPS supplying channels or described bypass power supply passage powering load;When the normally-closed contact of described first A.C. contactor KM1 disconnect, normally opened contact Guan Bi time, described double-cricuit supply is by described maintenance supplying channels powering load.
In practice, the switching mode of switch has two kinds manually or automatically, and in view of the effect of described on line type UPS power-supply system is continual powering load, described power change-over switch and described bypass changeover switch all adopt the mode of automatic switchover to carry out closed and disconnected.Therefore, described on line type UPS power-supply system also includes voltage collection circuit and microcontroller, and described voltage collection circuit gathers the voltage of described double-cricuit supply and the voltage of the outfan of described UPS supplying channels;Described microcontroller connects described voltage collection circuit, described power change-over switch and described by-pass switch, the Guan Bi of power change-over switch and described by-pass switch and disconnection according to the Control of Voltage of the voltage of described double-cricuit supply and described UPS supplying channels outfan.
Preferably, described by-pass switch and described service switch are made up of the second A.C. contactor KM2 and the three A.C. contactor KM3;The normally opened contact KM32 of described second A.C. contactor KM2, described second A.C. contactor the normally-closed contact KM32 of AC coil KM22 and described 3rd A.C. contactor KM3 be sequentially connected in series the described by-pass switch of composition;The normally opened contact KM31 of described 3rd A.C. contactor KM3, described 3rd A.C. contactor KM3 the normally-closed contact KM22 of AC coil KM32 and described second A.C. contactor KM2 be sequentially connected in series the described service switch of composition.Such arrangement is set so that described by-pass switch and described service switch constitute interlocking state, further ensure that the power supply of this system is only by a supplying channels powering load.
