Mfundo yogwira ntchito ya UPS yapaintaneti

Pamene UPS yapaintaneti imayendetsedwa ndi gridi yamagetsi nthawi zonse, kulowetsa kwamagetsi kuchokera ku gridi kumasefedwa ndi fyuluta ya phokoso kuti ichotse kusokoneza kwakukulu mu gridi, ndi mphamvu yoyera ya AC ingapezeke. Ikulowa mu rectifier kwa rectification ndi zosefera, ndikusintha mphamvu ya AC kukhala mphamvu yosalala ya DC, zomwe kenako zimagawidwa m'njira ziwiri. Njira imodzi imalowa mu charger kuti iwononge batire, ndi njira ina imapereka inverter. Komabe, inverter imasintha mphamvu ya DC kukhala 220V, 50Mphamvu ya Hz AC kuti katundu agwiritse ntchito. Pamene mains mphamvu yasokonezedwa, kulowetsa kwa mphamvu ya AC kwatha ndipo chowongolera sichikugwiranso ntchito. Pakadali pano, batire imatuluka ndikupereka mphamvu ku inverter, zomwe zimasintha mphamvu ya DC kukhala mphamvu ya AC kuti igwiritsidwe ntchito ndi katundu. Choncho, za katundu, ngakhale mphamvu ya mains kulibenso, katunduyo sanayime chifukwa cha kusokonezeka kwa mains mphamvu ndipo amatha kugwira ntchito bwino.

Mfundo yogwirira ntchito ya UPS yosunga zobwezeretsera ndikuti pamene magetsi a gridi ali abwinobwino, mzere umodzi wa mains mphamvu amatcha batire kudzera pa chowongolera, pamene mzere wina wa mphamvu za mains poyamba umakhazikika ndi chowongolera magetsi, imatenga kusokoneza kwina kwa gridi, ndiyeno mwachindunji amapereka mphamvu kwa katundu kudzera bypass lophimba. Panthawi ino, batire ili m'malo othamangira mpaka itatsekedwa kwathunthu ndikulowa m'malo oyandama. UPS ndi yofanana ndi chowongolera chomwe chili ndi vuto lowongolera ma voltage, zomwe zimangowonjezera kusinthasintha kwa matalikidwe a mains voteji ndipo sizipanga kusintha kulikonse "kuwononga magetsi" monga kusakhazikika pafupipafupi komanso kupotoza kwa ma waveform komwe kumachitika pa gridi yamagetsi. Pamene voteji kapena mafupipafupi a gridi yamagetsi amadutsa kuchuluka kwa UPS, kuti, m'mikhalidwe yachilendo, kulowetsa kwa mphamvu ya AC kwatha, charger imasiya kugwira ntchito, betri imatuluka, ndipo inverter imayamba kugwira ntchito motsogozedwa ndi dera lowongolera, kuchititsa inverter kupanga 220V, 50Mphamvu ya Hz AC. Pakadali pano, makina opangira magetsi a UPS amasinthira ku inverter kuti apitilize kupereka mphamvu pazonyamula. Inverter ya UPS yosunga zobwezeretsera nthawi zonse imakhala pamalo osungira magetsi.

Mfundo yogwirira ntchito ya UPS yolumikizidwa pa intaneti ndikuti mphamvu ya mains ikakhala yabwinobwino, amapereka mwachindunji mphamvu katundu kuchokera mains mphamvu. Pamene mains mphamvu ndi otsika kapena apamwamba, imakhazikika ndi gawo lokhazikika la UPS mkati ndi zotuluka. Pamene mphamvu ya mains ndi yachilendo kapena mphamvu imadulidwa, imasinthidwa kukhala magetsi osinthika a batri kudzera pakusintha kosintha. Makhalidwe ake ndi: wide input voltage range, phokoso lochepa, kukula kochepa, ndi zina., koma palinso nthawi yosintha. Komabe, poyerekeza ndi UPS yosunga zobwezeretsera, chitsanzo ichi chili ndi chitetezo champhamvu, ndipo inverter output voltage waveform ndiyabwinoko, zambiri sine wave.
