Kev Nkag SiabCov Hluav Taws Xob Hluav Taws XobCov Khoom Siv Kev Nyab Xeeb Tseem Ceeb hauv Cov Txheej Txheem Hluav Taws Xob

Hauv ntiaj teb kev tsim hluav taws xob thiab kev nyab xeeb hauv tsev, lo lus "circuit breaker" tshwm sim ntau heev. Lub circuit breaker yog ib lub cuab yeej tseem ceeb uas tsim los tiv thaiv cov hluav taws xob 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 saib tob txog kev ua haujlwm, hom, thiab qhov tseem ceeb ntawm cov circuit breakers hauv cov kab ke hluav taws xob niaj hnub no.

Lub tshuab hluav taws xob tawg yog dab tsi?

Lub tshuab hluav taws xob (circuit breaker) yog lub tshuab hloov hluav taws xob uas siv tau los 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 muaj kev nyab xeeb dua. 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 cov hlau bimetallic uas kub thiab khoov thaum tam sim no siab dhau. Thaum cov hlau bimetallic khoov rau qee qib, nws ua rau lub tshuab hluav taws xob qhib, cuam tshuam lub voj voog.

2. Lub tshuab sib nqus: Lub tshuab no siv lub zog hluav taws xob. Thaum muaj luv luv, qhov tam sim no yuav tsim lub zog sib nqus uas muaj zog txaus los rub lub lev, yog li ntawd lub voj voog thiaj tawg.

Qee cov circuit breakers niaj hnub no muab ob qho tib si mechanisms rau kev tiv thaiv zoo dua thiab hu ua "dual function" circuit breakers.

Hom ntawm cov hluav taws xob tawg

Muaj ntau hom circuit breakers, txhua tus muaj lub hom phiaj tshwj xeeb:

1. Cov Circuit Breakers Txheem: Cov no yog cov circuit breakers feem ntau pom muaj nyob rau hauv cov tsev nyob thiab cov tsev lag luam. Lawv tiv thaiv kev thauj khoom ntau dhau thiab luv luv circuits.

2. Cov cuab yeej tiv thaiv hluav taws xob hauv av (GFCI): Cov cuab yeej tiv thaiv hluav taws xob no yog tsim los tiv thaiv cov teeb meem hauv av, uas tshwm sim thaum cov hluav taws xob xau los ntawm nws lub voj voog npaj tseg. GFCIs feem ntau siv rau hauv cov chaw ntub dej xws li chav dej thiab chav ua noj.

3. Cov cuab yeej txiav hluav taws xob Arc Fault Circuit Interrupter (AFCI): AFCIs yog tsim los nrhiav cov teeb meem arc uas ua rau muaj hluav taws xob kub hnyiab. Lawv muaj txiaj ntsig zoo rau hauv chav nyob thiab chav pw.

4. Cov Khoom Siv Hluav Taws Xob Me Me (MCBs): Cov khoom siv hluav taws xob no siv rau hauv cov ntawv thov hluav taws xob qis thiab tau tsim los rau kev mus ncig ntawm qhov tam sim no ntsuas tshwj xeeb.

5. Cov Khoom Siv Tam Sim No (RCD): Zoo ib yam li GFCI, RCD tiv thaiv kev poob hluav taws xob los ntawm kev kuaj pom qhov tsis sib npaug ntawm tam sim no.

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. Los ntawm kev kaw lub zog thaum muaj xwm txheej txaus ntshai, cov circuit breakers 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 kom zoo dua. Lawv tswj cov khoom siv hluav taws xob kom zoo, ua kom cov voj voog ua haujlwm raws li lawv lub peev xwm tsim. Qhov no tsis yog tsuas yog ua kom lub neej ntawm cov khoom siv hluav taws xob ntev dua xwb, tab sis kuj txo cov kev pov tseg hluav taws xob.

TXOJ CAI QHIA

Xaus lus, cov cuab yeej hluav taws xob yog ib feem tseem ceeb ntawm cov tshuab hluav taws xob niaj hnub no. Lawv tseem ceeb rau kev nyab xeeb ntawm cov tsev thiab cov lag luam vim lawv tiv thaiv kev thauj khoom ntau dhau, luv luv, thiab lwm yam kev ua txhaum hluav taws xob. Kev nkag siab txog ntau hom cuab yeej hluav taws xob thiab lawv cov haujlwm tuaj yeem ua rau tib neeg txiav txim siab tau zoo txog lawv cov tshuab hluav taws xob, thaum kawg txhim kho kev nyab xeeb thiab kev ua haujlwm zoo. Raws li thev naus laus zis txuas ntxiv hloov zuj zus, cov cuab yeej hluav taws xob yuav ua lub luag haujlwm tseem ceeb rau yav tom ntej ntawm kev nyab xeeb hluav taws xob.
