Video: Lub zog hluav taws xob siv rau dab tsi?
2024 Tus sau: Lynn Donovan | [email protected]. Kawg hloov kho: 2023-12-15 23:47
A fais fab mov unit (los yog PSU) converts mains ACtolow-voltage tswj DC zog rau lub internalcomponents ntawm lub computer. Ib txhia cov khoom siv fais fab muaj ib tug manualswitch forselecting input voltage, thaum lwm tus cia li hloov mus rau lub mains voltage.
Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog lub hwj chim txhais lus?
A fais fab mov yog ib feem uas muab khoom zog kom tsawg kawg yog ib qho hluav taws xob load. Feem ntau, itconvertsone hom hluav taws xob mus rau lwm tus, tab sis nws kuj tseem hloov pauv ib hom ntawm lub zog - xws li assolar, mechanical, lossis chemical - rau hauv hluav taws xob zog. A fais fab mov muab cov khoom siv hluav taws xob zog.
Ib yam li ntawd, AC DC fais fab yog dab tsi? Nyob rau hauv direct tam sim no ( DC ), cov hluav taws xob (tam sim no) tsuas yog ntws hauv ib qho kev taw qhia. Electric chargeinalternating tam sim no ( AC ), ntawm qhov tod tes, hloov cov kev taw qhia ib ntus. Qhov voltage hauv AC circuitsalsoperiodically thim rov qab vim qhov kev hloov pauv tam sim no.
Qhov thib ob, cov khoom siv twg siv DC fais fab?
- Cov khoom siv fais fab. Feem ntau cov hluav taws xob hluav taws xob los ntawm phab ntsa hluav taws xob tawm hauv alternating tam sim no daim ntawv.
- Převod AC na TXK Hloov tam sim no yuav tsum tau convertedtodirect tam sim no (DC) los ntawm ib tug rectifier.
- Siv rau DC tam sim no. DC tam sim no feem ntau siv rau powersmalllelectronics.
- Cov khoom siv hluav taws xob.
- Roj teeb.
Muaj pes tsawg hom fais fab mov muaj?
Nyob ntawd yog peb qhov loj yam powersupplies : unregulated (tseem hu ua brute force), linearregulated, thiab hloov. Ib tug plaub hom powersupply Circuit Court hu ua ripple-regulated, yog ib tug hybrid ntawm "brute quab yuam" thiab "hloov" tsim, andmerits ib tug subsection rau nws tus kheej.

Dab tsi ua rau lub qhov hluav taws xob muaj hluav taws xob tsawg?
Ib qho laj thawj uas lub qhov hluav taws xob yuav muaj lowvoltageis uas nws hnav tawm. Cov hluav taws xob hluav taws xob tuaj yeem hnav tawm tib yam li txhua yam khoom siv lossis cov khoom siv hluav taws xob.Qhov txuas tsis tu ncua thiab tshem tawm cov hlua rau hauv lub qhov hluav taws xob tuaj yeem loosen thiab hnav cov kev sib txuas
Chav hluav taws xob hloov hluav taws xob yog dab tsi?
Chav hloov. ib cheeb tsam uas muaj kev sib dhos ntawm cov khoom siv hluav taws xob rau kev tswj thiab kev tiv thaiv hluav taws xob circuits. chav hloov pauv tuaj yeem cuam tshuam rau lub substation tab sis tsuas muaj cov keyboards xwb. lub ntsiab hloov mus rau cais tawm hluav taws xob yog nyob rau hauv lub ntsiab switchroom
Yuav ua li cas koj xaim lub tshuab hluav taws xob mus rau qhov ntsuas hluav taws xob?
Muaj peb cov xov hlau uas yuav tsum tau txuas mus rau qhov tseeb regulator davhlau ya nyob twg. Weld lub regulator mount rau lub tsheb laij teb ncej. Txuas lub regulator rau lub mount. Txuas lub roj teeb zoo cable hlau - feem ntau yog liab - rau tus tswj. Polarize lub generator los yog alternator los ntawm tus regulator
Koj siv lub ntsuas hluav taws xob ntsuas hluav taws xob li cas?
Txhawm rau siv lub ntsuas hluav taws xob, kov ib qho kev sojntsuam rau ib lub xaim lossis kev sib txuas thiab lwm qhov kev sojntsuam mus rau qhov sib txawv ntawm cov xaim lossis kev sib txuas
Puas yog txhua lub tshuab hluav taws xob muaj GFCI qhov hluav taws xob?
Duplex (ob chav) qhov hluav taws xob muaj nyob rau ntawm lub tshuab hluav taws xob nqa tau thiab txhua qhov khoom siv 120 volts. Hauv av txhaum kev tiv thaiv qhov hluav taws xob (GFCI) yog qhov tshwj xeeb ntawm qee cov qauv thiab tiv thaiv tus neeg siv los ntawm hluav taws xob shocks
