Xaiv cov me me Circuit Court breaker breaker (MCB) rau DC daim ntawv thov koom nrog ntau yam kev txiav txim siab tseem ceeb. Ntawm no yog ib qib zuj zus ntawm-kauj ruam qhia:
1. Txiav txim siab lub nra tam sim no
Laij tag nrho cov tam sim no uas Circuit Court yuav kos. Qhov no feem ntau ua tiav raws li cov ntsuas ntsuas ntawm cov khoom siv sib txuas.
2. Xaiv lub MCB kev ntaus nqi
Xaiv ib qho MCB nrog qhov kev ntaus nqi tam sim no (hauv) ntau dua cov thauj khoom tam sim no tab sis tsis tshaj qhov ntsuas hluav taws xob siab tshaj plaws rau cov ntaub qhwv thiab cov khoom siv. Cov kev ntaus nqi suav nrog 1a, 2a, 4a, 6a, 10a, thiab lwm yam.
3. Xav txog qhov muaj peev xwm tawg
Qhov muaj peev xwm tawg (tseem hu ua luv luv-CircuitA) yog qhov kev txhaum ntau tshaj lub McB tuaj yeem cuam tshuam. Xyuas kom meej tus nqi no haum rau koj daim ntawv thov, feem ntau hais hauv Ka.
4. Xaiv hom raug
Txog cov ntawv thov DC, MCBs feem ntau yog hom feem ntau yog hom B, C, lossis D raws lawv tus cwj pwm. Hom C yog siv tau siv rau cov motors thiab inductive thauj khoom, thaum ntaus b yog tsim nyog rau kev tawm tsam.
5. Voltage ntsuam xyuas
Nco ntsoov tias MCB yog nyob rau qhov tshwj xeeb DC voltage ntawm koj lub system. Cov DC voltage ntsuas suav nrog 12v, 24v, 48v, thiab lwm yam.
6. Xav txog ib puag ncig ib puag ncig
Txheeb xyuas cov kev ntsuas ib puag ncig (IP kev ntsuas) yog tias MCB yuav raug cov hmoov av, ya raws, lossis huab cua sov.
7. Ua raws cai thiab cov qauv
Nco ntsoov tias MCB ua raws li cov qauv muaj feem xyuam xws li IEC 60947-2 rau cov kab ke nrog Circuit Court.
8. Cov lus pom zoo
Tham cov neeg tsim khoom cov txheej txheem rau cov qauv MCB tshwj xeeb, raws li cov qauv sib txawv yuav muaj cov cai lossis cov yam ntxwv.
9. Kuaj thiab ntawv pov thawj
Saib rau MCBs uas tau sim thiab muaj ntawv pov thawj rau siv hauv DC daim ntawv thov kom paub tseeb thiab ntseeg tau.
Tag
Los ntawm kev ua raws li cov kauj ruam no, koj tuaj yeem xaiv MCB tsim nyog rau koj daim ntawv thov DC, kom muaj kev nyab xeeb thiab kev ntseeg tau hauv koj lub tshuab hluav taws xob.
