Described battery pack is connected with DC master row by intelligent charge unit.
Described DC master row detects switch control unit by voltage stabilizing and connects load.
The utility model can ensure power supply safety reliably, when 1# electrical network, the arbitrary electrical network of 2# electrical network normally work, preferentially can to batteries charging, even if at 1# electrical network, 2# electrical network without under electric power thus supplied, battery pack is when lower than set point, generator works in time, while work power supply, carries out intelligent charge again to battery pack.The uninterrupted power supply for power supply continuously so repeatedly, all power switch unit are without the need to switching.And at 1# electrical network, 2# electrical network, battery pack, generator, any power supply group or many group people for power-off overhaul time, this power supply all does as usual to work and as usual exports control voltage, does not truly switch free of discontinuities device power supply.
Accompanying drawing explanation
Below the content that width accompanying drawing every in the utility model specification is expressed is briefly described:
Fig. 1 the present invention designs and does not successfully switch free of discontinuities device powersupply system block schematic illustration;
Fig. 2 circuit concrete scheme of the present invention phase three-wire three schematic diagram;
Fig. 3 circuit concrete scheme of the present invention three-phase and four-line schematic diagram.
Embodiment
As shown in Figure 1, electric supply installation comprises electrical network, battery pack and generator, wherein electrical network is provided with two groups, is respectively 1# electrical network, 2# electrical network, and electrical network and generator are Alternating Current Power Supply, respectively by switch element, rectification stable pressuring unit access DC master row, battery pack is direct current supply, between access DC master row, switch control unit gathers described DC master row power source information, and outputing control signals to generator and switch element, DC master row connects load.
Not consumed energy in 1# electrical network, the normal situation of 2# mains supply.1# electrical network, 2# electrical network, battery pack, when voltage is all extremely lower than set point, or artificially overhaul, or when natural calamity its three groups all cannot be powered, generator automatic reception instruction, start to work power supply, continues to connect uninterrupted flicker free.
1# electrical network, 2# electrical network exchange and input power supply simultaneously, and end of incoming cables is provided with surge absoption and EMC treatment circuit, increase surge absoption and EMC treatment circuit by the prime inputted at electrical network, make noiseless, the stable normal work of late-class circuit.
Because of the difference by each electric unit concrete scheme and equipment, there are the different modes of connection of phase three-wire three and three-phase and four-line, therefore the present invention is not by the restriction of the mode of connection, flexible machine becomes, single-phase also can be simpler, as shown in Figure 2, 1# electrical network, 2# electrical network is inputted by terminal through switch element, in order to avoid external interference, surge absoption and EMC treatment circuit have been done in end of incoming cables namely, concrete every individually by rectifier rectification, can be independently-powered, then the voltage after every commutating phase connects, high preferential characteristic is selected according to voltage, every phase voltage is all likely in real-time power supply, do not power and be in the state of standing ready mutually, so another advantage of the present invention is reliability, alternative high, but power consumption is little.Voltage after connection mutually ends and does not interfere with each other.According to the characteristic of above-mentioned circuit of the present invention, Width funtion 85V ~ 800V input voltage condition of work, as long as two-way electrical network has any phase voltage of any road electrical network normal, this supply unit is work as usual.Form power supply in real time, do not switch free of discontinuities and power.
As shown in Figure 3, Fig. 3 invention circuit arrangement three-phase and four-line, similar with the functional effect of Fig. 2, the zero line being exactly many two-way electrical network inputs, and this suits measures to local conditions according to client's needs, and flexible machine becomes alternative supply power mode.1# electrical network, 2# electrical network are inputted by terminal through switch element, in order to avoid external interference, surge absoption and EMC treatment circuit have been done in end of incoming cables namely, concrete every individually by rectifier rectification, can be independently-powered, then the voltage after every commutating phase connects, select high preferential characteristic according to voltage, every phase voltage, all likely in real-time power supply, is not powered and is in the state of standing ready mutually, so another advantage of the present invention is reliability, alternative high, but power consumption is little.Voltage after connection mutually ends and does not interfere with each other.According to the characteristic of above-mentioned circuit of the present invention, Width funtion 85V ~ 800V input voltage condition of work, as long as two-way electrical network has any phase voltage of any road electrical network normal, this supply unit is work as usual.Form power supply in real time, do not switch free of discontinuities and power.
Irresistible natural calamity or in particular cases 1# electrical network, 2# electrical network all stop power supply, at this moment battery-powered quiet continuous on.Battery-powered input is connected on the input of circuit arrangement of the present invention all the time, is connected in the middle of circuit, by selection circuit, once circuit voltage is in set point, on battery voltage continues immediately, without poor any time.Battery circuit does not consume energy when being in detected state, because there is reverse cut-off circuit to protect.This is also a large characteristic of circuit of the present invention.
Under extreme conditions, 1# electrical network, 2# electrical network do not restore electricity or are all in inspecting state, and battery pack power is about to exhaust or also will overhaul, and at this moment manually or automatically, generator work ahead, power supply continues normal, and power supply is normal, exports DC normal.
1# electrical network, 2# electrical network preferentially power one-level response, battery-powered secondary response, finally just takes turns to generator operation, and this response circuit choice relation is simple classical circuit, is built in the middle of power circuit of the present invention, belongs to testing circuit.The perfect reliability of Here it is circuit.
The perfect reliability of circuit also shows, in order to ensure the round-the-clock power supply of battery pack, just must have Intelligent Measurement and charging device, charge at any time for the battery pack lower than set point.When 1# electrical network, the arbitrary electrical network of 2# electrical network normally work, preferentially can to batteries charging, even if at 1# electrical network, 2# electrical network without under electric power thus supplied, battery pack is when lower than set point, generator works in time, while work power supply, carries out intelligent charge again to battery pack.The uninterrupted power supply for power supply continuously so repeatedly, all power switch unit are without the need to switching.
Circuit exports power supply DC load less than 1000 watts, DC3.3V ~ 50V continuously adjustabe.If when determining load power consumption voltage, power source internal components and parts of the present invention can be replaced with the components and parts of adaptive withstand voltage and power consumption.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection range of the present utility model without to improve.
