Cov Hom Circuit Breaker thiab Phau Ntawv Qhia Xaiv

Cov cuab yeej hluav taws xob (circuit breakers) yog cov khoom tseem ceeb hauv cov tshuab hluav taws xob, ua haujlwm ua cov khoom siv tiv thaiv kom tsis txhob muaj kev puas tsuaj los ntawm kev thauj khoom ntau dhau thiab luv luv. Cov cuab yeej hluav taws xob no yog tsim los txiav txim siab thaum pom muaj qhov tsis zoo, ua kom muaj kev nyab xeeb ntawm lub tshuab hluav taws xob thiab nws cov neeg siv. Tsab xov xwm no yuav kawm txog cov haujlwm, hom, thiab qhov tseem ceeb ntawm cov cuab yeej hluav taws xob hauv cov ntawv thov hluav taws xob niaj hnub no.

Lub luag haujlwm tseem ceeb ntawm lub circuit breaker yog qhib thiab kaw lub voj voog hluav taws xob. Tsis zoo li cov fuses ib txwm muaj, uas yuav tsum tau hloov tom qab lawv tawg, cov circuit breakers tuaj yeem rov pib dua tom qab tripping, ua rau lawv yooj yim dua thiab ua tau zoo dua kev daws teeb meem tiv thaiv hluav taws xob. Thaum muaj teeb meem hluav taws xob tshwm sim, xws li overload (tam sim no tshaj qhov peev xwm ntsuas ntawm lub voj voog) lossis luv luv (tam sim no ntws los ntawm txoj kev tsis xav tau), lub circuit breaker ntes tau qhov txawv txav thiab cuam tshuam cov dej ntws ntawm tam sim no, tiv thaiv kev phom sij xws li hluav taws xob hluav taws xob lossis khoom siv puas tsuaj.

Muaj ntau hom circuit breakers sib txawv, txhua hom tsim los rau cov kev siv thiab ib puag ncig tshwj xeeb. Cov hom feem ntau suav nrog:

1. Lub Tshuab Hluav Taws Xob Me Me (MCB)Siv rau hauv cov tsev nyob thiab cov lag luam los tiv thaiv kev thauj khoom ntau dhau thiab luv luv. MCBs yog me me thiab yooj yim rau nruab rau hauv cov thawv faib khoom.
2. Cov Khoom Siv Hluav Taws Xob Uas Nyob Twj Ywm (RCCB)Lub tshuab hluav taws xob no tseem hu ua lub cuab yeej hluav taws xob seem (RCD), thiab yog tsim los tiv thaiv kev raug hluav taws xob los ntawm kev kuaj pom qhov tsis sib npaug ntawm cov hluav taws xob. Yog tias ib tug neeg kov cov xov hlau uas muaj hluav taws xob, RCCB yuav tawg, thiab txiav cov hluav taws xob.
3. Lub tshuab hluav taws xob xau av (ELCB)Zoo ib yam li RCCB, ELCB siv los nrhiav qhov tsis ua haujlwm hauv av thiab tiv thaiv kev poob hluav taws xob. ELCBs tseem ceeb heev rau hauv cov chaw ntub dej xws li chav dej thiab sab nraum zoov.
4. Lub Tshuab Hluav Taws Xob Cua (ACB)Hom circuit breaker no siv rau hauv kev siv hauv kev lag luam thiab tuaj yeem tswj tau qhov ntsuas tam sim no siab. Cov cua circuit breakers siv los tiv thaiv cov kab ke hluav taws xob loj thiab tuaj yeem ua haujlwm manually lossis tsis siv neeg.
5. Cov Hluav Taws Xob Sib Nqus HydraulicCov cuab yeej hluav taws xob no siv kev sib xyaw ua ke ntawm cov txheej txheem thermal thiab magnetic los qhib lub voj voog. Lawv feem ntau yog siv rau ntawm cov tshuab hluav taws xob loj uas xav tau kev tiv thaiv overload thiab luv luv.

Qhov tseem ceeb ntawm cov circuit breakers tsis tuaj yeem hais dhau lawm. Lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb ntawm cov khoom siv hluav taws xob thiab tiv thaiv tib neeg thiab khoom vaj khoom tsev los ntawm kev phom sij ntawm cov hluav taws xob tsis ua haujlwm. Tsis tas li ntawm kev nyab xeeb, cov circuit breakers kuj pab txhawb kev txhim kho kev ntseeg siab ntawm lub tshuab hluav taws xob. Los ntawm kev tiv thaiv kev puas tsuaj rau cov khoom siv thiab txo qis lub sijhawm tsis ua haujlwm, lawv pab tswj kev ua haujlwm zoo hauv cov chaw nyob thiab chaw ua lag luam.

Tsis tas li ntawd xwb, kev nce qib ntawm thev naus laus zis tau ua rau muaj kev tsim cov cuab yeej hluav taws xob ntse, uas muaj peev xwm txhim kho xws li kev saib xyuas deb. Cov khoom siv niaj hnub no tuaj yeem muab cov ntaub ntawv siv hluav taws xob tiag tiag, ua rau cov neeg siv siv hluav taws xob tau zoo tshaj plaws thiab txheeb xyuas cov teeb meem ua ntej lawv loj hlob.

Hauv lus yooj yim, cov cuab yeej hluav taws xob yog cov khoom siv kev nyab xeeb tseem ceeb uas tiv thaiv cov kab ke hluav taws xob los ntawm kev thauj khoom ntau dhau thiab luv luv.Muaj ntau hom circuit breakers, uas haum rau ntau yam kev siv, ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm kev teeb tsa hluav taws xob. Nrog rau kev nce qib ntawm thev naus laus zis, yav tom ntej ntawm circuit breakers zoo li ci ntsa iab, vim tias kev tsim kho tshiab yuav ua rau lawv muaj txiaj ntsig zoo dua thiab ua tau zoo hauv kev tiv thaiv cov khoom siv hluav taws xob. Kev nkag siab txog lub luag haujlwm thiab qhov tseem ceeb ntawm circuit breakers yog qhov tseem ceeb rau txhua tus neeg ua haujlwm nrog cov kab ke hluav taws xob, txawm tias yog kws tshaj lij lossis tus tswv tsev uas tab tom nrhiav kev nyab xeeb.

 

Lub tshuab hluav taws xob tawg yog dab tsi?
Lub tshuab hluav taws xob tawg yog ib lub cuab yeej tiv thaiv hluav taws xob uas tsim los tiv thaiv lub voj voog hluav taws xob ntawm kev puas tsuaj los ntawm cov hluav taws xob ntau dhau uas cov khoom siv tuaj yeem nqa tau zoo (overcurrent). Nws lub luag haujlwm tseem ceeb yog cuam tshuam cov hluav taws xob kom tiv thaiv cov khoom siv thiab tiv thaiv hluav taws.
