Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment 1
As can be seen from the schematic diagram of the prior art of Fig. 1, the main ac working power supply that what the input power of UPS body was selected is voltage is 380V, frequency is 50Hz, what out-put supply was selected is voltage is 380V, frequency is the output AC power source of 50Hz, the major loop of main ac working power supply system comprises main power switch connected successively, filter, rectifier, inverter, inverse static quick closing valve, output switch, wherein main power switch is connected with the output of main ac working power supply, and the input of output AC power source is connected with output switch.Because the civil power of input, namely main ac working power supply, UPS inversion exports the difference all had on voltage magnitude and total harmonic distortion in various degree, therefore needs the existence of filter, rectifier and inverter.
Meanwhile, main ac working power supply system also comprises a feedback loop be made up of bypass static switch, this bypass static switch input between filter and rectifier, the output of bypass static switch is inverse between static switch and output switch.Interlocking design between bypass static switch and inversion static switch, can realize discharge and recharge interlocking, ensure that circuit has a loop to connect between bypass static switch and inverse static switch.
In addition, UPS body also comprises the battery system connecting main ac working power supply, and battery system comprises DC switch, and the input of DC switch is connected with the output of battery, between the rectifier that the output of DC switch accesses main AC power supply system and inverter.Because battery supplied is direct current, therefore need the existence of inverter.
When main ac working power supply, when namely commercial power supply is normal, civil power is directly by the direct power supply to the device of main ac working power supply system, when commercial power supply is not enough, is powered, ensure that the supply of electric power by battery system to equipment.
Embodiment 2
The schematic diagram of the prior art of comparison diagram 1, inputted and a theory diagram exported mutually as can be seen from Fig. 2 three-phase of the present invention, the present invention has technically carried out larger improvement in prior art, the spacer assembly that the main AC power supply system that improvements are not only embodied in UPS body interior is set up, is also embodied in the AC power supply system for subsequent use of setting up.
First, in the inside of main AC power supply system, set up isolating transformer and inversion isolating transformer, object is that the input and output side in order to ensure main AC power supply system can realize electrical isolation, avoids affecting its internal components.Because in prior art, the main alternating current input power supplying of power supply and alternating current input power supplying for subsequent use are same road power supply, when the electric voltage frequency of AC power fluctuates, the pfc circuit operating state of rectifier, the power supply quality of UPS under bypass mode pattern can be had influence on, cause the power supply hidden danger of load, therefore can only work under voltage fluctuation-15% ~+15%, frequency fluctuation ± 5% situation.Isolating transformer is positioned at the output of main power switch, and object avoids the electric voltage frequency influence of fluctuations of main ac working power supply to the pfc circuit operating state of filter.Inversion isolating transformer is between the output and the input of inversion static switch of inverter, and object avoids output AC power source electric voltage frequency to fluctuate to impact inverter operating state.
Secondly, filter in the inside of main AC power supply system, rectifier, inverter become as a whole UPM module with DC static switch, and adopt the UPM module of identical configuration parallel with one another, battery system is interconnected between DC static switch and each UPM module, when reaching guarantee wherein a road or multichannel UPM module go wrong, circuit normally works always to have other UPM to ensure, avoids because only have a road UPM to cause risk to the overall stall of UPS.
Again, in the outside of main AC power supply system, increase the AC power for subsequent use that the voltage that one is not same road power supply with main ac working power supply is 380V, frequency is 50Hz, the major loop of this AC power supply system for subsequent use comprises the AC power for subsequent use, bypass input switch, bypass isolating transformer, pressurizer, maintenance stabilized switch, bypass AC power and the Backup Power Switch that are connected successively, and Backup Power Switch accesses the major loop of main ac working power supply system by bypass static switch.Meanwhile, be also provided with bypass inspection switch, between the output and the output of output switch of bypass AC power, the loop formed with Backup Power Switch and bypass static switch is in parallel.It should be noted that bypass AC power and output AC power source all select that Shi mono-road voltage is 220V, frequency is the AC power of 50Hz, Shi tri-road voltage is 380V, frequency is the AC power of 50Hz to only have main ac working power supply to select.In fact, the effect of bypass isolating transformer is the same with the effect of the isolating transformer of main ac working power supply, and object avoids the pressurizer of the voltage fluctuation of AC power for subsequent use to its inside to impact.The maintenance voltage stabilizing circuit of output end of voltage stabilizer is single-pole double-throw switch (SPDT), and object is for power-off inspection during regular maintenance, and main ac working power supply is because must connect, so this is not arranged.Meanwhile, when overhauling, simultaneously by the bypass inspection switch together action after it, the effect of commutation circuit simultaneously can be reached.
In sum, the setting of multiple electrical isolation transformer of the present invention and multiple anti-power failure, can strictly in industry can not the equipment of power-off protect.
Embodiment 3
As Fig. 2 three-phase input and theory diagram exported mutually and difference as the theory diagram that Fig. 3 three-phase inputs and three-phase exports is that the bypass AC power of standby power system and output AC power source all adopt that three road voltages are 380V, frequency is the AC power of 50Hz, other are arranged all equally.Be-30% ~+25% of rated value to the scope of application of AC power, and the energy powering load that when, frequency drift serious in the wave distortion of line voltage, (diesel engine generator is powered) also can normally use AC power to provide; Rectifier adopts controlled multiple-pulse commutation technique, change in-30% ~+25% of off-rating at the voltage of AC power, frequency off-rating ± 10% in change time, rectifier output voltage fluctuation range≤1% can be ensured, meet the power supply to inverter.When UPS is in bypass state, be the safe and effective operation of proof load, civil power need export after isolation in voltage stabilizing, output accuracy 220VAC/380VAC ± 1 ~ 5%.Simultaneously bypass cabinet has the defencive function such as overvoltage, under-voltage, overcurrent, phase shortage, misphase, mechanical breakdown.You need to add is that, the multiple electrical isolation that design of the present invention adopts is arranged and multiple anti-power failure arranges the position being not limited to show in accompanying drawing.
The technical scheme described in the embodiment of the invention described above is just in order to understand know-why of the present invention better; and with the technical scheme itself being confined to embodiment and describing; the all right cross-utilization mutually of technical scheme of embodiment; also good effect can be realized; explanation is not enumerated, all within the protection range of application claims at this.Can be known by technology contents of the present invention, the quadruple isolating and protecting of rectification isolating transformer of the present invention, inversion isolating transformer, bypass isolating transformer and pressurizer composition, bypass independently can be powered separately, interlocking design between bypass static switch and inversion static switch, DC static switch realizes discharge and recharge interlocking, thus solves grid supply quality.The present invention can provide safe, reliable, stable power supply, other equipment normal operations of safeguard industries enterprise.
