Cov kws ua choj tsim cov txheej txheem thiab qhia meej cov khoom tawg uas ua tau raws li cov kev cai thiab kev nyab xeeb.
-
Cov Chaw Tswj Xyuas Chaw saib xyuas cov tshuab tawg ua kom muaj kev nyab xeeb hauv tsev thiab tiv thaiv kev poob qis.
-
Cov tswv tsev Tej zaum yuav cuam tshuam nrog cov khoom tawg thaum hloov kho, kho, lossis kho lub zog.
Yuav Ua Li Cas Xaiv Txoj Cai Circuit Breaker
Kev xaiv lub Circuit Court breaker zoo yuav tsum tau ua tib zoo soj ntsuam ntawm koj lub cev cov yam ntxwv. Cov yam tseem ceeb uas yuav tau xav txog muaj xws li:
1. Kev ntsuas hluav taws xob thiab tam sim no
Xyuas kom lub breaker phim koj lub cev qhov hluav taws xob thiab qhov xav tau tam sim no.
-
Qhov hluav taws xob:
-
Cov chaw nyob feem ntau siv 120V lossis 240V (North America), lossis 230V (Tebchaws Europe).
-
Kev lag luam thiab kev lag luam tshuab yuav xav tau 480V lossis siab dua.
-
-
Tam sim no:
-
15A-20A rau cov teeb pom kev dav dav thiab qhov hluav taws xob
-
30A-50A rau cov khoom siv loj xws li qhov cub thiab tshuab ziab khaub ncaws
-
100A lossis ntau dua rau cov khoom siv hauv tsev
-
Nrog koj cov lus qhia tshwj xeeb lossis tus kws tshaj lij hluav taws xob los txiav txim siab cov cai.
2. Tus lej ntawm tus ncej
Tus naj npawb ntawm cov ncej nyob ntawm hom Circuit Court:
-
Ib leeg-ncej breakers yog siv rau 120V circuits, xws li teeb pom kev hauv tsev los yog qhov hluav taws xob.
-
Ob tug ncej breakers tuav 240V circuits rau cov khoom siv xws li tshuab ziab khaub ncaws los yog dej rhaub.
-
Ntau tus ncej breakers yog siv nyob rau hauv peb-theem systems uas muaj nyob rau hauv industrial chaw.
3. Muaj peev xwm tawg
Lub peev xwm tawg yog qhov ua txhaum siab tshaj plaws tam sim no lub breaker tuaj yeem cuam tshuam yam tsis ua haujlwm.
-
Cov chaw nyob feem ntau xav tau 6kA txog 10kA.
-
Kev lag luam thiab kev lag luam ib puag ncig yuav xav tau 25kA lossis ntau dua, nyob ntawm kev tsim qauv.
Xaiv lub breaker uas muaj peev xwm tawg tsis txaus yuav ua rau cov cuab yeej tsis ua haujlwm. Nws feem ntau pom zoo kom tso cai rau qhov kev nyab xeeb tshaj qhov ntsuas tam sim no.
4. MCB Trip Curves
Kev mus ncig curves txiav txim siab sai npaum li cas ib qho me me Circuit Court breaker (MCB) teb rau overcurrent:
-
B Curve: Kev mus ncig ntawm 3-5 zaug ntsuas tam sim no; haum rau cov teeb pom kev zoo thiab cov khoom siv hauv tsev.
-
C Curve: Kev mus ncig ntawm 5-10 lub sijhawm ntsuas tam sim no; siv nrog cov motors lossis cov khoom siv nrog kev sib tw nruab nrab.
