Hauv ntiaj teb kev nyab xeeb hluav taws xob, cov ntsiab lus me me feem ntau ua rau qhov sib txawv loj tshaj plaws. Ib qho kev nthuav dav - feem ntau nkag siab yuam kev lossis saib tsis taus - yog lub peev xwm tawg ntawm MCBs. Yog tias koj tab tom ua haujlwm hauv kev teeb tsa, kev saib xyuas, lossis kev tsim qauv, kev nkag siab qhov kev ntsuas tseem ceeb no tuaj yeem tiv thaiv cov cuab yeej puas tsuaj loj - lossis phem dua, hluav taws xob txaus ntshai.
Dab tsi yog Kev Sib Tw Muaj Peev Xwm ntawmMCBTiag Tiag?
Cias muab, lub peev xwm tawg ntawm MCB (Miniature Circuit Breaker) yog hais txog qhov siab tshaj plaws tam sim no nws tuaj yeem cuam tshuam yam tsis muaj kev puas tsuaj rau nws tus kheej lossis hluav taws xob. Nws yog lub Circuit Court breaker lub peev xwm los nres qhov khiav ntawm hluav taws xob thaum lub sij hawm luv luv Circuit Court los yog txhaum.
Thaum muaj qhov tshwm sim tam sim ntawd lossis ua txhaum, MCB yuav tsum ua tam sim ntawd. Yog tias qhov tam sim no dhau ntawm qhov ntsuas qhov sib tsoo lub peev xwm, lub cuab yeej yuav ua tsis tau - tej zaum yuav ua rau muaj kev puas tsuaj loj xws li hluav taws kub, arcing, lossis khoom siv tsis ua haujlwm. Tias yog vim li cas kev nkag siab thiab raug xaiv qhov muaj peev xwm tawg yog qhov tseem ceeb.
Qhov tseem ceeb ntawm kev xaiv txoj cai tawg muaj peev xwm
1. Kev nyab xeeb ua ntej
Ib qho MCB uas tsis muaj peev xwm tawg tsis txaus yuav tsis tuaj yeem ua qhov txhaum cai tam sim no, ua rau muaj kev puas tsuaj rau ob qho tib si Circuit Court thiab cov neeg ua haujlwm. Kev xaiv kom raug ua kom lub cuab yeej yuav mus zoo yam tsis muaj tawg lossis tawg.
2. Ua raws li cov qauv hluav taws xob
Cov lej hluav taws xob hauv feem ntau cov cheeb tsam tau txiav txim siab tias lub peev xwm tawg ntawm MCBs yuav tsum muaj ntau dua lossis sib npaug rau qhov siab tshaj plaws tam sim no luv luv tam sim no ntawm kev teeb tsa. Kev ua tsis tau raws li cov qauv no tuaj yeem ua rau tsis ua raws cai thiab muaj teeb meem kev cai lij choj.
3. Kev ntseeg tau
Qhov raug ntsuas MCBs tiv thaiv tsis yog tsuas yog cov xaim thiab cov khoom siv xwb tab sis kuj tseem ua rau muaj kev ruaj ntseg ntawm cov hluav taws xob tag nrho. Kev poob qis vim qhov tsis raug ntsuas cov khoom tawg tuaj yeem ua rau cov khoom lag luam poob thiab raug nqi kho.
Tej yam uas cuam tshuam lub peev xwm tawg
1. Qhov chaw ntawm kev teeb tsa
Qhov txhaum theem ntawm qhov chaw uas MCB raug teeb tsa ua lub luag haujlwm tseem ceeb. Kev teeb tsa hauv nroog lossis cov uas nyob ze rau lub zog hluav taws xob tuaj yeem muaj qhov cuam tshuam ntau dua.
2. Hom ntawv thov
Kev lag luam ib puag ncig feem ntau xav tau MCBs siab dua li cov ntawv thov kev lag luam hauv tsev lossis teeb pom kev lag luam vim muaj cov khoom hnyav dua thiab ntau lub tshuab.
3. Qhov System Design
Tag nrho cov kev tsim network - suav nrog cable loj, lub peev xwm hloov pauv, thiab qhov kev ncua deb ntawm qhov chaw muab khoom - tuaj yeem cuam tshuam rau qhov xav tau kev tawg ntawm MCB.
Yuav Ua Li Cas Txiav Txim Siab Zoo Rau Koj Cov Kev Xav Tau
Xaiv qhov muaj peev xwm tawg ntawm MCB suav nrog kev ntsuas qhov ua txhaum tam sim no ntawm qhov chaw teeb tsa. Qhov no feem ntau tuaj yeem suav tau raws li qhov system impedance lossis txheeb xyuas siv cov ntaub ntawv los ntawm cov chaw muab kev pabcuam.
Nov yog qee qhov kev ntsuas kev muaj peev xwm sib tw uas koj yuav ntsib:
6kA (6000 Amps) - Hom rau cov chaw nyob lossis cov chaw lag luam uas pheej hmoo tsawg
10kA (10000 Amps) - Haum rau kev lag luam siab dua lossis teeb tsa kev lag luam
16kA thiab siab dua - Yuav tsum muaj rau cov haujlwm hnyav hnyav lossis kev teeb tsa nrog lub peev xwm luv luv
Nco ntsoov sab laj nrog tus kws tshaj lij hluav taws xob tsim nyog kom paub tseeb tias kev suav thiab xaiv kom raug.
Kev Saib Xyuas thiab Kev Ntsuas Lub Sij Hawm: Tsis txhob hla nws
Txawm tias MCBs zoo tshaj plaws yuav tsum tau kuaj xyuas qee zaus. Plua plav, corrosion, lossis kev qaug zog sab hauv tuaj yeem txo lawv cov txiaj ntsig zoo thaum lub sijhawm. Kev ntsuam xyuas tsis tu ncua thiab kev tiv thaiv kev saib xyuas kom ntseeg tau tias lub peev xwm tawg ntawm MCBs tseem nyob ruaj khov thiab txhim khu kev qha.
Kev xav zaum kawg: Ua cov kev xaiv paub los tiv thaiv koj qhov system
Lub peev xwm tawg ntawm MCB tsis yog ib qho kev nthuav dav - nws yog ib qho tseem ceeb hauv kev ua kom muaj kev nyab xeeb, kev ua tau zoo, thiab kev ua raws li cov khoom siv hluav taws xob. Siv sijhawm los nkag siab thiab siv lub tswv yim no kom zoo tuaj yeem txuag nyiaj, poob sijhawm, thiab ua neej nyob.
