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

Lub tshuab hluav taws xob tawg yog dab tsi?

Lub tshuab hluav taws xob (circuit breaker) yog lub tshuab 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 zoo dua rau kev tiv thaiv lub voj voog. Cov tshuab hluav taws xob yog qhov tseem ceeb rau kev tiv thaiv hluav taws xob, kev puas tsuaj rau cov khoom siv, thiab lwm yam kev phom sij uas cuam tshuam nrog kev ua haujlwm tsis zoo ntawm hluav taws xob.

Yuav ua li cas cov circuit breakers ua haujlwm

Cov hluav taws xob ua haujlwm raws li ob lub hauv paus tseem ceeb: thermal thiab magnetic.

1. Lub tshuab tiv thaiv kub: Lub tshuab no siv ib daim hlau bimetallic uas khoov thaum qhov hluav taws xob siab dhau. Thaum qhov hluav taws xob siab tshaj qhov nqi uas tau teem tseg, daim hlau yuav khoov txaus kom ua rau lub tshuab hluav taws xob tawg, yog li ntawd 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 ua rau lub tshuab hluav taws xob tawg.

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. Cov Circuit Breakers Me Me (MCB): Cov circuit breakers no feem ntau siv rau hauv cov tsev nyob thiab cov tsev lag luam los tiv thaiv kev thauj khoom ntau dhau thiab luv luv circuits. Lawv yog compact thiab tuaj yeem tswj cov theem qis mus rau nruab nrab tam sim no.

2. Lub Tshuab Hluav Taws Xob Uas Nyob Twj Ywm (RCCB): Cov khoom siv no tiv thaiv kev raug hluav taws xob los ntawm kev ntes qhov hluav taws xob tsis sib npaug. Yog tias pom muaj qhov tsis zoo, RCCB yuav ua haujlwm thiab txiav qhov hluav taws xob.

3. Cov Khoom Siv Hluav Taws Xob Uas Nyob Twj Ywm (ELCB): Zoo ib yam li Cov Khoom Siv Hluav Taws Xob Uas Nyob Twj Ywm (RCCB), cov ELCB tiv thaiv kev puas tsuaj ntawm lub ntiaj teb. Lawv tseem ceeb heev rau hauv cov chaw ntub dej xws li chav dej thiab chav ua noj.

4. Cov Tshuab Hluav Taws Xob Cua (ACB): Cov tshuab hluav taws xob cua siv rau hauv kev siv hauv kev lag luam los tswj cov theem tam sim no siab thiab muab kev tiv thaiv tiv thaiv kev thauj khoom ntau dhau, luv luv, thiab av txhaum.

5. Cov Hydraulic Magnetic Circuit Breakers: Cov no feem ntau siv rau hauv cov tshuab hluav taws xob loj dua thiab muab cov kev daws teeb meem zoo rau kev tiv thaiv cov hluav taws xob muaj teeb meem siab.

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 kev phom sij ntawm hluav taws xob, tiv thaiv lub neej thiab khoom vaj khoom tsev. Cov circuit breakers txiav cov hluav taws xob hauv cov 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 ua kom ntseeg tau tias cov khoom siv hluav taws xob ua haujlwm hauv qhov kev nyab xeeb, yog li ntawd nws lub neej ua haujlwm ntev dua thiab txo cov nqi kho.

Hauv kev xaus lus

Tag nrho hauv txhua yam, 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 yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm zoo. Kev nkag siab txog ntau hom circuit breakers thiab lawv cov haujlwm tuaj yeem pab cov tswv tsev thiab cov lag luam txiav txim siab zoo txog lawv cov tshuab hluav taws xob. Thaum thev naus laus zis txuas ntxiv mus, cov circuit breakers yuav txuas ntxiv hloov pauv, ua rau lawv lub luag haujlwm tseem ceeb hauv kev tiv thaiv peb cov khoom siv hluav taws xob.
