Cov teeb meem tshwm sim hauv kev siv fais fab inverter?
UPS Suav txhais tau tias “lub zog tsis cuam tshuam”. Lub hwj chim UPS tshwj xeeb yog tsim los rau cov chaw nres tsheb, nrog cov rectifiers thiab inverters ua cov khoom tseem ceeb, thiab cov khoom siv hluav taws xob DC raws li cov khoom siv hluav taws xob. Nws muab qhov hluav taws xob tsis tu ncua thiab qhov zaus tsis tu ncua rau cov khoom siv tseem ceeb xws li kev soj ntsuam cov tshuab, cov twj paj nruag automation, cov chaw taws teeb sib txuas lus thiab microcomputer systems hauv substation. Uninterruptible ups power supply unit. Dab tsi yog cov teeb meem tshwm sim hauv kev siv fais fab inverters?
Yuav ua li cas lub hwj chim inverter xaiv ib tug hloov sine yoj thiab ib tug ntshiab sine yoj?
1. Ob lub waveforms sib txawv, cov ntshiab sine yoj yog qhov ruaj khov thiab sib npaug ntawm cov mains, thiab cov hloov yoj yog cov analog ntawm lub mains.
2. Kev kho nthwv dej feem ntau yog qhov hnyav hnyav. Pure resistive loads uas ua hauj lwm los ntawm resistive Cheebtsam yog hu ua resistive loads, xws li: xov tooj ntawm tes, computers, LCD TVs, induction cookers, dawb woven teeb, hluav taws xob kiv cua, mov cookers, hluav taws xob kiv cua, me me printers, thiab lwm yam yog tag nrho cov resistive loads.
3. Lub sine yoj ntshiab yog sib npaug rau lub nroog hluav taws xob thiab tuaj yeem nqa tau cov khoom siv hluav taws xob, thiab feem ntau yog siv rau kev thauj khoom inductive. Cov khoom siv hluav taws xob nrog cov coils yog hu ua inductive loads, xws li lub cev muaj zog, compressors, relays, LED teeb, tub yees, freezers, cua txias, thiab lwm yam. Lub zog ntawm lub sijhawm pib deb tshaj qhov ntsuas fais fab (kwv yees li 3-7 zaug).
Thaum lub inverter siv, yog tias muaj kev kaw lossis tswb, yog vim li cas?
1) Txawm hais tias lub zog ntawm cov khoom siv hluav taws xob uas tau tsav ntau tshaj qhov ntsuas hluav taws xob tus nqi ntawm lub inverter.
2) Seb lub inverter zoo txuas nrog lub roj teeb thiab cov khoom siv hluav taws xob
3) Yog tias nws raug tso tseg thaum siv, txawm tias nws yog lub tswb ntsuas kub, lub sijhawm no, nws tuaj yeem siv txuas ntxiv tom qab nres rau lub sijhawm.
