Qhov ntsuas kev khiav hauj lwm voltage ntawm qis- cov khoom siv hluav taws xob hluav taws xob yog hais txog tus nqi hluav taws xob uas ua kom cov cuab yeej ua haujlwm ib txwm ua raws li cov xwm txheej teev tseg. Nws feem ntau yog hais txog tus nqi ntsuas hluav taws xob ntawm cov neeg sib cuag. Cov hauv qab no yog cov lus piav qhia ntxaws txog qhov ntsuas kev ua haujlwm voltage ntawm qis- cov khoom siv hluav taws xob voltage:
Txhais thiab Ua Haujlwm
Qhov ntsuas kev khiav hauj lwm voltage yog tus nqi hluav taws xob uas cov khoom siv hluav taws xob tuaj yeem tiv taus raws li kev ua haujlwm ib txwm muaj, tsis yog qhov siab tshaj plaws lossis qhov tsawg kawg nkaus.
Rau ntau-phase circuits, qhov ntsuas kev khiav hauj lwm voltage yog hais txog theem - mus rau -phase voltage (ie, kab voltage).
Voltage Ntau
Qhov ntsuas hluav taws xob ntawm qis- cov khoom siv hluav taws xob hluav taws xob feem ntau txwv rau AC 1200V thiab DC 1500V. Cov khoom siv nrog cov nqi qis dua li cov no suav tias yog qis-voltage.
Cov khoom siv hluav taws xob qis qis feem ntau muaj qhov ntsuas hluav taws xob ntawm 380V (cov khoom siv hauv kev lag luam) lossis 220V (cov khoom siv hauv tsev).
Qhov sib txawv ntawm Lwm qhov Voltage Parameters
Rated Insulation Voltage: Muaj feem xyuam rau kev ntsuas kev ua haujlwm ntawm dielectric, feem ntau tsis qis dua qhov ntsuas kev ua haujlwm voltage.
Rated Pulse Withstand Voltage: Hais txog qhov siab tshaj qhov muaj peev xwm ntawm qhov system uas cov khoom siv hluav taws xob tuaj yeem tiv taus.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov ntsuas hluav taws xob ua haujlwm tsis zoo ib yam li "qhov siab tshaj qhov hluav taws xob nws tuaj yeem tiv taus," qhov kawg yog cov lus tsis raug.
International thiab Domestic Standards
Lub International Electrotechnical Commission (IEC) thiab Suav cov qauv hauv tebchaws (xws li GB / T 2900.18) txhais cov khoom siv hluav taws xob tsawg- cov khoom siv hluav taws xob raws li cov khoom siv nrog AC rated voltage Tsawg dua lossis sib npaug li 1200V lossis DC rated voltage Tsawg dua lossis sib npaug li 1500V.
Rated khiav hauj lwm voltage yog ib qho tseem ceeb parameter nyob rau hauv kev tsim thiab xaiv ntawm tsawg-voltage khoom siv hluav taws xob. Cov khoom siv hluav taws xob sib txuam yuav tsum raug xaiv raws li qhov tseeb daim ntawv thov scenario (piv txwv li, muaj 380V lossis tsev neeg 220V), thaum tseem sib txawv nws cov luag haujlwm sib txawv hauv kev cuam tshuam rau cov tsis xws li rwb thaiv tsev voltage.
