Lub luag haujlwm ntawmCov khoom siv hluav taws xob Moulded case (MCBs)tsis tuaj yeem raug kwv yees qis hauv kev tswj hwm kev nyab xeeb thiab kev ua haujlwm ntawm cov kab ke hluav taws xob. Cov khoom siv hluav taws xob molded case yog cov khoom tseem ceeb hauv cov kab ke faib hluav taws xob, muab kev tiv thaiv overcurrent thiab luv luv. Hauv tsab blog no, peb yuav tshawb nrhiav qhov tseem ceeb ntawm cov khoom siv hluav taws xob molded case thiab lawv lub luag haujlwm hauv kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov kab ke hluav taws xob.
Cov khoom siv hluav taws xob uas muaj pwm (molded case circuit breakers) yog tsim los tiv thaiv kom tsis txhob muaj hluav taws xob ntau dhau, uas yuav tshwm sim los ntawm ntau yam xws li kev siv hluav taws xob ntau dhau, kev siv hluav taws xob luv luv lossis kev ua txhaum hauv av. Cov khoom siv hluav taws xob no yog qhov tseem ceeb rau kev tiv thaiv kev puas tsuaj rau cov kab ke hluav taws xob thiab cov khoom siv txuas nrog thiab txo qhov kev pheej hmoo ntawm hluav taws xob kub hnyiab. Ntxiv rau kev tiv thaiv cov kab ke los ntawm kev siv hluav taws xob ntau dhau, cov khoom siv hluav taws xob uas muaj pwm (molded case circuit breakers) pab cais cov circuits uas ua txhaum thiab rov qab muaj hluav taws xob sai sai yog tias muaj kev sib tsoo.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov molded case circuit breakers yog lub peev xwm los muab cov kev teeb tsa kev tiv thaiv uas hloov kho tau thiab meej. Qhov no txhais tau tias cov chaw teeb tsa ntawm lub circuit breaker tuaj yeem hloov kho kom ua tau raws li cov kev xav tau tshwj xeeb ntawm lub kaw lus hluav taws xob, kom ntseeg tau tias muaj kev tiv thaiv overcurrent zoo tshaj plaws. Cov molded case circuit breakers ua rau muaj kev teeb tsa kev tiv thaiv uas hloov kho tau thiab muaj kev ywj pheej thiab hloov pauv tau yooj yim, ua rau lawv haum rau ntau yam kev siv.
Ntxiv rau kev muab kev tiv thaiv overcurrent, cov molded case circuit breakers ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ntseeg tau thiab kev ua haujlwm zoo ntawm cov kab ke hluav taws xob. Los ntawm kev kuaj pom thiab cais cov teeb meem tam sim ntawd, cov circuit breakers no pab txo qhov tsis ua haujlwm thiab kev cuam tshuam hluav taws xob. Qhov no tseem ceeb heev rau cov ntawv thov tseem ceeb xws li cov chaw ua haujlwm, cov tsev lag luam thiab cov chaw kho mob, qhov twg qhov kev muab hluav taws xob tsis tu ncua yog qhov tseem ceeb.
Tsis tas li ntawd,cov khoom siv hluav taws xob moldedtau tsim los ua raws li cov qauv kev nyab xeeb thiab kev cai lij choj nruj, kom ntseeg tau tias lawv muab kev tiv thaiv txhim khu kev qha thiab muaj zog rau cov kab ke hluav taws xob. Raws li qhov xav tau kev nyab xeeb hluav taws xob txuas ntxiv mus, kev siv cov molded case circuit breakers tau dhau los ua ntau dua hauv kev teeb tsa tshiab thiab cov haujlwm kho dua tshiab. Nrog lawv cov ntaub ntawv pov thawj ntawm kev ntseeg tau thiab kev ua tau zoo, cov circuit breakers no tau dhau los ua ib feem tseem ceeb ntawm cov kab ke hluav taws xob niaj hnub.
Nws tseem tsim nyog sau tseg tias kev nce qib ntawm thev naus laus zis tau ua rau muaj kev tsim cov yam ntxwv tshiab hauv cov khoom siv hluav taws xob molded case, xws li kev saib xyuas deb thiab kev sib txuas lus. Cov yam ntxwv no ua rau muaj kev saib xyuas deb thiab tswj cov khoom siv hluav taws xob, muab cov ntaub ntawv tiag tiag ntawm lawv qhov xwm txheej thiab kev ua tau zoo. Qhov no tsis yog tsuas yog ua kom pom kev pom thiab kev tswj hwm lub cev hluav taws xob zoo dua xwb, tab sis kuj tseem ua rau muaj kev saib xyuas thiab daws teeb meem, thaum kawg ua rau muaj kev ntseeg siab thiab kev txuag nqi.
Hauv kev xaus lus, cov khoom siv hluav taws xob molded case circuit breakers yog ib qho tseem ceeb hauv cov kab ke faib hluav taws xob, muab kev tiv thaiv overcurrent tsim nyog thiab pab txhim kho kev nyab xeeb, kev ntseeg siab thiab kev ua haujlwm zoo ntawm cov kab ke hluav taws xob. Nrog rau kev teeb tsa kev tiv thaiv uas tuaj yeem hloov kho tau, kev ua haujlwm siab thiab kev ua raws li cov qauv kev nyab xeeb, cov khoom siv hluav taws xob molded case circuit breakers yog ib qho khoom muaj nqis tseem ceeb hauv kev ua kom cov kab ke hluav taws xob ua haujlwm zoo. Raws li qhov xav tau kev nyab xeeb hluav taws xob thiab kev ntseeg siab txuas ntxiv mus, lub luag haujlwm ntawm cov khoom siv hluav taws xob molded case hauv cov kab ke hluav taws xob yuav tsuas yog tseem ceeb dua.
