UPSand #39; s qeb:
Feem ntau, tshuab kom raws sijhawm yog muab faib ua peb pawg, ua rau lub cia (lossis offline), kab-sib tham sib thiab ob-conversion (Internet). Txawv manufacturers muaj ib configurations sib txawv ntawm cov neeg ib ce tuaj raws li cov nqe, kev siv, thiab tso cai, raws li lawv muaj siab rau yam khoom ntau yam zoo, xaiv tus kom raws sijhawm.
Yuav ua li cas mus xaiv ib ce uninterruptible zog mov
1, ua ntej kom koj nrhiav chaw muaj ntaub ntawv yuav tsum tau charge, feem ntau qhov nruab nrab ib ncig 200W zog PC cav tov los yog muaj lub computer, Mac 300W neeg rau zaub mov ntawm 300W thiab 600W, lwm yam li hwj huam qhov tseem ceeb yuav xa mus rau cov lus qhia ntaus ntawv. Raw li cov xovxwm no yuav tsum tau cov purchase ntawm ib tug.
2, secondly, ib tug yuav tsum to taub qhov ntsuam xyuas kom raws sijhawm hwj huam, muaj ob txoj kev: khees zog (VA) thiab lub hwj huam tso zis sij (w), qhov txawv yog los vim yog muaj cov hwj huam reactive, conversion ntawm ob yog: qhov zoo tshaj yuav khees zog fais fab * = sij tso zis ntau zog. Li ntawd thaum lub sij hawm ntawm purchase los xam
Zaus thiab qib-zaus ntawm 3, mob ib ce faib ua ob tug. Zaus thyristor SCR rectifier, IGBT inverter, bypass thiab hwj huam zaus boost rho tawm transformer. Vim yog lub rectifier thiab transformer lag luam zaus zog zaus 50 Hz, raws li lub npe qhia zaus kom raws sijhawm.
