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, lo lus "circuit breaker" muaj ntau lub ntsiab lus. Lub circuit breaker yog lub qhov hloov hluav taws xob tsis siv neeg uas tsim los tiv thaiv lub voj voog hluav taws xob ntawm kev puas tsuaj los ntawm kev thauj khoom ntau dhau lossis luv luv circuits. Nws lub luag haujlwm tseem ceeb yog cuam tshuam kev ntws ntawm hluav taws xob thaum pom qhov txhaum, yog li tiv thaiv kev phom sij xws li hluav taws xob lossis kev puas tsuaj rau cov khoom siv. Tsab xov xwm no saib tob txog ntau yam ntawm circuit breakers, lawv cov hom, kev ua haujlwm, thiab lawv qhov tseem ceeb hauv cov kab ke hluav taws xob niaj hnub no.
Kev ua haujlwm ntawm lub tshuab hluav taws xob
Lub tshuab hluav taws xob (circuit breaker) yog ib yam khoom siv tiv thaiv kev nyab xeeb rau lub voj voog hluav taws xob. Thaum cov hluav taws xob ntws hla lub voj voog ntau tshaj qhov tau teem tseg, lub tshuab hluav taws xob yuav txiav nws tus kheej, txiav lub zog. Qhov kev ua no yog qhov tseem ceeb rau kev tiv thaiv kom tsis txhob kub dhau thiab muaj hluav taws kub los ntawm cov hluav taws xob ntau dhau. 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 tau txiav, ua rau lawv yog qhov kev xaiv yooj yim dua thiab zoo dua rau kev tiv thaiv lub voj voog.
Hom ntawm cov hluav taws xob tawg
Muaj ntau hom circuit breakers, txhua hom tsim los rau cov kev siv thiab ib puag ncig tshwj xeeb. Cov hom feem ntau suav nrog:
1. Miniature Circuit Breaker (MCB): Cov circuit breakers no siv rau hauv cov tsev nyob thiab cov lag luam los tiv thaiv kev overload thiab luv circuits. MCBs yog compact thiab tuaj yeem yooj yim ntsia tau rau hauv cov laug cam faib khoom.
2. Cov Khoom Siv Hluav Taws Xob Uas Nyob Twj Ywm (RCCB): Cov khoom siv no, tseem hu ua RCDs, yog tsim los tiv thaiv kev raug hluav taws xob los ntawm kev ntes qhov tsis sib npaug ntawm cov hluav taws xob. Yog tias pom muaj qhov tsis zoo, RCCB yuav tawg, txiav qhov chaw muab hluav taws xob.
3. Lub Tshuab Hluav Taws Xob Tawm Hluav Taws Xob (ELCB): Ib yam li RCCB, ELCB siv los nrhiav qhov teeb meem hauv av thiab tiv thaiv kev raug hluav taws xob. Lawv tseem ceeb heev rau cov chaw ntub dej, xws li chav dej thiab thaj chaw sab nraum zoov.
4. Cov Tshuab Hluav Taws Xob Cua (ACB): Cov tshuab hluav taws xob no siv rau hauv kev siv hauv kev lag luam thiab tuaj yeem tswj tau qhov ntsuas tam sim no siab. ACBs yog tsim los tiv thaiv cov kab ke hluav taws xob loj thiab tuaj yeem ua haujlwm tes lossis tsis siv neeg.
5. Cov Tshuab Hluav Taws Xob Sib Nqus Hydraulic: Cov tshuab hluav taws xob no siv kev sib xyaw ua ke ntawm cov txheej txheem cua sov thiab hlau nplaum los qhib lub voj voog. Lawv feem ntau siv rau hauv cov tshuab hluav taws xob loj uas muaj cov hluav taws xob siab.
Qhov Tseem Ceeb ntawm Circuit Breakers hauv Cov Tshuab Hluav Taws Xob
Qhov tseem ceeb ntawm cov circuit breakers tsis tuaj yeem hais dhau. Lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov kab ke hluav taws xob. Los ntawm kev tiv thaiv kev thauj khoom ntau dhau thiab luv luv circuits, circuit breakers tsis yog tsuas yog pab tiv thaiv cov khoom siv hluav taws xob, tab sis lawv kuj pab tiv thaiv lub neej ntawm cov tib neeg uas yuav raug kev phom sij hluav taws xob.
Ntxiv rau kev nyab xeeb, cov khoom siv hluav taws xob kuj pab txhim kho kev ua haujlwm ntawm cov tshuab hluav taws xob. Los ntawm kev txiav cov circuits uas puas lawm sai sai, cov khoom siv hluav taws xob tuaj yeem txo qhov tsis ua haujlwm thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj loj rau cov khoom siv hluav taws xob. Qhov no tseem ceeb heev rau cov chaw lag luam thiab kev lag luam, qhov twg kev muab hluav taws xob tsis tu ncua yog qhov tseem ceeb rau kev ua haujlwm.
Hauv kev xaus lus
Hauv kev xaus lus, cov circuit breakers yog ib feem tseem ceeb ntawm cov tshuab hluav taws xob niaj hnub no. Lawv lub peev xwm los cuam tshuam cov hluav taws xob thaum muaj qhov txhaum yog qhov tseem ceeb rau kev tiv thaiv tib neeg thiab khoom vaj khoom tsev. Muaj ntau hom circuit breakers sib txawv, haum rau ntau yam kev siv, yog li kev nkag siab txog lawv txoj haujlwm thiab qhov tseem ceeb yog qhov tseem ceeb rau txhua tus neeg koom nrog kev tsim hluav taws xob lossis kev nyab xeeb. Thaum thev naus laus zis txuas ntxiv mus, cov circuit breakers yuav txuas ntxiv hloov pauv, txhim kho lawv lub luag haujlwm hauv kev tiv thaiv peb cov tshuab hluav taws xob.
