Ib vim li cas qhov hluav taws xob muaj muaj lowvoltageis tias nws yog hnav tawm. Hluav taws xob qhov hluav taws xob tuaj yeem hnav zoo ib yam li txhua yam khoom siv lossis khoom siv hluav taws xob. Qhov txuas tsis tu ncua thiab tshem tawm cov hlua khi rau hauv qhov hluav taws xob tuaj yeem loosen thiab hnav cov kev sib txuas.
Ib yam li ntawd, dab tsi ua rau qis voltage ntawm qhov hluav taws xob?
Cov kab hluav taws xob, kev hloov pauv tsis ua haujlwm lossis qhov siab siab hauv lub tsev hluav taws xob hluav taws xob yog ib qho ntawm ob peb qhov teeb meem uas cuam tshuam rau phab ntsa qhov hluav taws xob voltage . Cov rwb thaiv tsev tsis zoo ua ke nrog highamperage thiab tsis kam tuaj yeem yog qhov hluav taws kub nyob rau yav tom ntejifthe qhov teeb meem ntawm tsis tshua muaj hluav taws xob at ib qhov hluav taws xob tsis yog confronted thiab tswj.
Ib tug kuj yuav nug, yuav ua li cas yog tias voltage tsawg dhau lawm? Voltage heev Siab, Tsawg dhau . Qhov hluav taws xob uas yog ib yam nkaus siab tuaj yeem ua rau tsis ua hauj lwm ntxov ntawm cov khoom siv hluav taws xob thiab hluav taws xob (piv txwv li Circuit Court boards) vim overheating. hluav taws xob qib nce mus, qhov tam sim no raug txo thiab qis tam sim no feem ntau sib npaug rau tsawg dua heatgeneration nyob rau hauv lub motor windings.
Kuj Paub, dab tsi ua rau under voltage?
Undervoltage Cov xwm txheej feem ntau yog tshwm sim los ntawm undersizedor overloadedutility thiab chaw transformers. Thaum lub sijhawm xav tau siab tshaj plaws thiab / lossis thaum cov khoom siv hluav taws xob tau ntsib teeb meem, qhov kev xav tau ntau tshaj qhov muaj peev xwm ntawm qhov hloov pauv thiab ua rau hluav taws xob poob.
Dab tsi yog txhais los ntawm qhov tsis tshua muaj hluav taws xob?
IEC Txhais Lub International Electrotechnical Commission (IEC) txhais cov khoom siv tsis tshua muaj hluav taws xob raws li hluav taws xob 50-1000V AC los yog 120-1500V DC. Hauv cov hluav taws xob hluav taws xob tsis tshua muaj hluav taws xob feem ntau yog hais txog cov ntsiab lus voltages raws li siv los ntawm domestic thiab lub teeb industrialand coj mus muag cov neeg siv khoom.
