Ua hauj lwm hauv internet UPS

Thaum hauv internet UPS yog powered los ntawm lub hwj huam grid nquag, Cov voltage input ntawm daim phiaj yog filtered los ntawm ib lub limtiam nrov kom tshem tau high-frequency cuam tshuam rau hauv daim phiaj, thiab ntshiab AC fais fab yuav tau txais. Nws nkag mus rau lub rectifier rau rectification thiab filtering, thiab converts lub HWJ HUAM AC fais fab rau hauv smooth DC fais fab tuag, uas yog ces muab faib ua ob paths. Ib txog kev nkag mus rau tus nqi them lub roj teeb, thiab lwm yam khoom siv hauv lub inverter. tiam sis, Tus inverter converts dc hwj huam rau 220V, 50Hz AC fais fab rau lub load siv. Thaum lub hwj huam loj yog cuam tshuam, Cov input ntawm AC fais fab muaj tau txiav tawm thiab cov rectifier yog tsis ua hauj lwm. lub sij hawm no, Lub roj teeb discharges thiab muab zog rau lub inverter, Uas ces converts DC hwj huam rau hauv AC fais fab siv los ntawm cov load. Li ntawd, yog li, rau lub load, Txawm hais tias lub hwj huam loj lawm tshwm sim, Lub load twb tsis tso tseg vim cov interruption ntawm lub ntsiab hwj huam thiab tseem khiav lag luam nquag.

Tus thawj xibfwb ntawm backup UPS yog tias thaum lub hwj huam mov ntawm daim phiaj yog ib qho zoo, Ib kab ntawm mains fais fab tsub lub roj teeb los ntawm ib tug rectifier, Thaum lwm kab ntawm lub hwj huam loj yog chiv stabilized los ntawm ib tug automatic voltage regulator, absorbs tej daim phiaj cuam tshuam, Thiab ces ncaj qha khoom siv fais fab rau lub load los ntawm ib tug bypass hloov. txij ntawm no mus, Lub roj teeb yog nyob rau hauv ib lub xeev them kom txog thaum nws mas them thiab nkag mus rau hauv ib lub xeev ntab them lub xeev. UPS yog sib npaug rau ib regulator uas tsis voltage kev cai, Uas tsuas txhim kho cov amplitude fluctuation ntawm lub ntsiab voltage thiab tsis ua tej yam kev kho kom haum rau cov "hluav taws xob" Xws li frequency instability thiab waveform distortion uas tshwm sim rau lub hwj huam grid. Thaum cov voltage los yog frequency ntawm lub hwj huam grid tshaj cov input ntau yam ntawm lub UPS, uas yog, muaj tej yam tshwm sim, Cov input ntawm AC fais fab muaj tau txiav tawm, Tus charger nres ua hauj lwm, roj teeb, thiab cov inverter pib ua hauj lwm raws li tus tswj circuit Court, ua rau cov inverter los ua kom muaj 220V, 50Hz AC fais fab tuag. lub sij hawm no, Lub UPS hwj huam mov lawv switches rau lub inverter mus ntxiv supplying hwj huam rau lub load. Tus inverter ntawm lub backup UPS yog ib txwm nyob rau hauv ib lub hwj huam backup mov lub xeev.

Tus thawj xibfwb hauv internet interleaved UPS yog tias thaum lub hwj huam loj yog dab tsi, Nws ncaj qha khoom siv fais fab tuag rau lub load ntawm lub hwj huam loj. Thaum lub ntsiab hwj huam tseem ceeb yog tsawg los yog siab, Nws yog stabilized los ntawm tus UPS thoob ntiaj teb stabilizing circuit court thiab tso zis. Thaum lub hwj huam loj yog abnormal los yog hwj huam yog txiav tawm, Nws yog converted rau roj teeb inverter hwj huam mov los ntawm ib conversion hloov. Cov cim xeeb ceem yog: ntau yam, suab nrov, luaj li cas, li ntawd., Tiam sis kuj switching lub sij hawm. tiam sis, piv nrog general backup UPS, Cov qauv no muaj zog tiv thaiv kev ua hauj lwm, thiab cov inverter tso zis voltage waveform zoo, feem ntau sine yoj.
