Nkag Siab Txog Cov Hluav Taws Xob Hluav Taws Xob: Cov Khoom Siv Kev Nyab Xeeb Tseem Ceeb Hauv Cov Tshuab Hluav Taws Xob**
Lo lus "circuit breaker" yog ib lo lus siv ntau hauv ntiaj teb kev tsim hluav taws xob thiab kev nyab xeeb hauv tsev. Cov circuit breakers yog cov khoom siv tseem ceeb uas tiv thaiv cov hluav taws xob los ntawm kev thauj khoom ntau dhau thiab luv luv, ua kom muaj kev nyab xeeb ntawm cov kab ke hluav taws xob thiab cov neeg siv lawv. Tsab xov xwm no yuav saib ze dua txog kev ua haujlwm, hom, thiab qhov tseem ceeb ntawm cov circuit breakers hauv cov kab ke hluav taws xob niaj hnub no.
Dab tsi yog ib qholub tshuab hluav taws xob?
Lub tshuab hluav taws xob (circuit breaker) yog lub tshuab hloov hluav taws xob uas txiav cov hluav taws xob hauv lub voj voog thaum nws pom tias muaj teeb meem tsis zoo, xws li muaj kev thauj khoom ntau dhau lossis luv luv. Tsis zoo li cov fuses, uas yuav tsum tau hloov tom qab lawv tawg, cov tshuab hluav taws xob tuaj yeem rov pib dua tom qab lawv tawg, ua rau lawv yooj yim dua thiab ua haujlwm tau zoo dua rau kev nyab xeeb hluav taws xob. Lawv feem ntau raug teeb tsa rau hauv cov vaj huam sib luag hluav taws xob thiab tseem ceeb rau kev tiv thaiv hluav taws xob thiab kev puas tsuaj rau cov khoom siv.
Cov hluav taws xob ua haujlwm li cas?
Cov hluav taws xob ua haujlwm raws li ob lub hauv paus tseem ceeb: thermal thiab magnetic.
1. Lub tshuab ua kom sov: Lub tshuab no siv daim kab xev bimetallic. Thaum lub zog tam sim no loj dhau, daim kab xev bimetallic yuav kub thiab khoov. Thaum nws khoov mus rau qee qib, nws yuav ua rau lub tshuab hluav taws xob qhib, yog li txiav lub voj voog.
2. Lub tshuab sib nqus: Lub tshuab no siv lub zog hluav taws xob. Thaum muaj hluav taws xob luv luv, qhov tam sim no yuav tsim lub zog sib nqus uas muaj zog txaus kom rub lub lev thiab rhuav lub voj voog.
Qee cov cuab yeej hluav taws xob niaj hnub no muab ob qho tib si los ua ke rau kev tiv thaiv zoo dua, muab kev teb zoo dua rau ntau yam kev ua txhaum hluav taws xob.
Hom ntawm cov hluav taws xob tawg
Muaj ntau hom circuit breakers, txhua tus muaj lub hom phiaj tshwj xeeb:
1. Lub Tshuab Hluav Taws Xob Txheem: Qhov no yog hom tshuab hluav taws xob feem ntau pom muaj nyob rau hauv cov tsev nyob thiab cov tsev lag luam. Lawv yog siv los tiv thaiv kev thauj khoom ntau dhau thiab luv luv.
2. Lub Tshuab Hluav Taws Xob Tiv Thaiv Kab Mob Hauv Av (GFCI): Lub tshuab hluav taws xob no yog siv los tiv thaiv kab mob hauv av. Kab mob hauv av yog kab mob uas tshwm sim thaum cov hluav taws xob xau los ntawm lub voj voog uas tau teev tseg. GFCIs feem ntau siv rau hauv cov chaw ntub dej xws li chav dej thiab chav ua noj kom tiv thaiv kev raug hluav taws xob.
3. Cov cuab yeej txiav hluav taws xob Arc Fault Circuit Interrupter (AFCI): AFCIs yog siv los nrhiav cov teeb meem arc uas ua rau muaj hluav taws xob. Lawv muaj txiaj ntsig zoo rau cov chaw nyob uas muaj kev pheej hmoo ntawm hluav taws xob ntau dua.
4. **Lub Tshuab Hluav Taws Xob Me Me (MCB)**: Siv rau hauv cov ntawv thov hluav taws xob tsawg, tsim los tiv thaiv kev thauj khoom ntau dhau thiab luv luv hauv cov hluav taws xob me me.
5. Cov Khoom Siv Hluav Taws Xob Uas Nyob Twj Ywm (RCCB): Cov khoom siv hluav taws xob no ntes tau qhov tsis sib npaug ntawm cov hluav taws xob thiab feem ntau yog siv los tiv thaiv kev raug hluav taws xob.
Qhov Tseem Ceeb ntawm Circuit Breakers
Qhov tseem ceeb ntawm cov circuit breakers tsis tuaj yeem hais dhau lawm. Lawv yog thawj kab tiv thaiv tiv thaiv kev phom sij ntawm hluav taws xob, tiv thaiv lub neej thiab khoom vaj khoom tsev. Cov circuit breakers txiav hluav taws xob cia li txiav thaum muaj xwm txheej txaus ntshai, pab tiv thaiv hluav taws xob, kev puas tsuaj rau cov khoom siv, thiab kev raug mob.
Tsis tas li ntawd xwb, cov cuab yeej hluav taws xob pab txhim kho kev ua haujlwm ntawm cov tshuab hluav taws xob. Los ntawm kev tiv thaiv kev thauj khoom ntau dhau, cov cuab yeej hluav taws xob pab tswj kev ua haujlwm ntawm cov khoom siv hluav taws xob thiab cov khoom siv, ua kom lawv lub neej ntev dua thiab txo cov nqi kho.
Cov Lus Qhia Tseem Ceeb
Tag nrho hauv txhua qhov, cov circuit breakers yog ib feem tseem ceeb ntawm cov tshuab hluav taws xob niaj hnub no. Lawv lub peev xwm los ntes thiab teb rau qhov tsis ua haujlwm ntawm hluav taws xob tsis yog tsuas yog txhim kho kev nyab xeeb xwb, tab sis kuj ua rau kev ua haujlwm ntawm cov khoom siv hluav taws xob zoo dua. Thaum thev naus laus zis txuas ntxiv mus, cov circuit breakers kuj yuav hloov zuj zus, suav nrog cov yam ntxwv ntse dua los txhim kho kev nyab xeeb thiab kev ntseeg siab. Kev nkag siab txog lub luag haujlwm thiab kev ua haujlwm ntawm cov circuit breakers yog qhov tseem ceeb rau txhua tus neeg uas ua haujlwm nrog cov khoom siv hluav taws xob, nrog rau cov tswv tsev uas xav kom ntseeg tau tias lawv cov tshuab hluav taws xob muaj kev nyab xeeb.
