Circuit Breaker thiab RCD: Kev Lav Fais Fab Zoo

Cov Circuit Breakers thiab RCDsNkag Siab Txog Lawv Lub Luag Haujlwm Hauv Kev Nyab Xeeb Hluav Taws Xob

Hauv ntiaj teb kev nyab xeeb hluav taws xob, ob qho tseem ceeb feem ntau los ua si: cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob seem (RCDs). Txawm hais tias ob qho tib si tau tsim los tiv thaiv cov circuits thiab tiv thaiv kev phom sij, lawv ua haujlwm sib txawv thiab tau tsim rau cov haujlwm tshwj xeeb. Kev nkag siab txog lub luag haujlwm ntawm cov khoom siv hluav taws xob thiab RCDs yog qhov tseem ceeb rau txhua tus neeg koom nrog kev teeb tsa hluav taws xob, kev saib xyuas lossis kev nyab xeeb.

Lub tshuab hluav taws xob tawg yog dab tsi?

Lub tshuab hluav taws xob (circuit breaker) yog lub tshuab hloov hluav taws xob uas tsim los tiv thaiv lub voj voog hluav taws xob kom tsis txhob raug puas tsuaj los ntawm kev siv hluav taws xob ntau dhau lossis luv luv. Thaum cov hluav taws xob ntws los ntawm lub voj voog ntau tshaj qhov tau teem tseg, lub tshuab hluav taws xob yuav cuam tshuam kev ntws hluav taws xob, ua rau "qhib" lub voj voog. Qhov kev ua no tiv thaiv lub cev hluav taws xob thiab cov khoom siv txuas nrog los ntawm kev tiv thaiv kev kub dhau thiab hluav taws kub.

Muaj ntau hom circuit breakers, suav nrog:

1. Miniature Circuit Breaker (MCB): Siv rau hauv cov ntawv thov hluav taws xob tsawg los tiv thaiv kev thauj khoom ntau dhau thiab luv luv.
2. Cov Khoom Siv Hluav Taws Xob Uas Nyob Twj Ywm (RCCB): Cov khoom siv no ntes tau qhov tsis sib npaug ntawm cov hluav taws xob thiab ua kom lub voj voog puas tsuaj kom tiv thaiv tau hluav taws xob poob siab.
3. Eleakage Circuit Breaker (ELCB): Zoo ib yam li RCCB, ELCB tiv thaiv kev puas tsuaj hauv av thiab cov dej ntws tawm.

RCD yog dab tsi?

Ib lub cuab yeej Residual Current Device (RCD), tseem hu ua Residual Current Circuit Breaker (RCCB), yog ib lub cuab yeej kev nyab xeeb uas qhib lub voj voog thaum twg nws pom tias muaj qhov tsis sib npaug ntawm cov xov hluav taws xob uas muaj sia thiab cov xov hluav taws xob tsis muaj zog. Qhov tsis sib npaug no tshwm sim thaum muaj kev ua haujlwm tsis zoo, xws li thaum ib tus neeg kov cov xov hluav taws xob uas muaj sia, ua rau raug hluav taws xob lossis raug hluav taws xob tua.

Cov RCDs yog tsim los teb sai sai (feem ntau hauv 30 milliseconds) kom tiv thaiv kev raug mob hnyav lossis kev tuag. Lawv tseem ceeb heev rau cov chaw ntub dej xws li chav dej thiab chav ua noj, qhov twg muaj kev pheej hmoo ntawm kev raug hluav taws xob ntau dua. RCDs tuaj yeem ntsia tau ua cov khoom siv sawv ntsug lossis koom ua ke rau hauv cov hluav taws xob breakers kom muab kev tiv thaiv ob npaug.

Qhov tseem ceeb ntawm cov hluav taws xob Circuit Court breakers thiab RCDs

Cov cuab yeej hluav taws xob thiab RCDs ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb ntawm hluav taws xob. Cov cuab yeej hluav taws xob tiv thaiv kev thauj khoom ntau dhau thiab luv luv, thaum RCDs tsom mus rau kev tiv thaiv kev poob hluav taws xob los ntawm kev ntes cov hluav taws xob xau. Ua ke lawv tsim ib lub kaw lus kev nyab xeeb uas txo qis kev pheej hmoo ntawm kev phom sij ntawm hluav taws xob.

1. Kev Tiv Thaiv Hluav Taws Kub: Cov cuab yeej hluav taws xob tiv thaiv kev kub hnyiab thiab hluav taws kub uas tshwm sim los ntawm kev siv hluav taws xob ntau dhau. Lawv tuaj yeem tawg thaum tsim nyog, tiv thaiv cov xov hlau thiab cov khoom siv kom tsis txhob puas tsuaj.

2. Kev Tiv Thaiv Kev Poob Hluav Taws Xob: RCDs yog qhov tseem ceeb rau kev tiv thaiv tib neeg ntawm kev poob hluav taws xob. Los ntawm kev txiav lub voj voog sai sai thaum pom qhov teeb meem, lawv tuaj yeem txo qhov kev pheej hmoo ntawm kev raug mob hnyav lossis kev tuag.

3. KEV UA RAWS LI TXOJ CAI: Muaj ntau txoj cai kev nyab xeeb hluav taws xob xav kom muaj kev teeb tsa cov circuit breakers thiab RCDs hauv cov tsev nyob thiab cov chaw ua lag luam. Kev ua raws li txoj cai tsis yog tsuas yog ua kom muaj kev nyab xeeb xwb tab sis kuj tiv thaiv cov tswv cuab ntawm kev lav phib xaub raws li txoj cai.

Hauv kev xaus lus

Hauv kev xaus lus, cov khoom siv hluav taws xob thiab cov khoom tiv thaiv kom tsis txhob xau av yog cov khoom tseem ceeb ntawm cov txheej txheem kev nyab xeeb hluav taws xob. Cov khoom siv hluav taws xob tiv thaiv kev thauj khoom ntau dhau thiab luv luv, thaum RCDs muab kev tiv thaiv tseem ceeb tiv thaiv kev poob hluav taws xob. Kev nkag siab txog kev ua haujlwm thiab qhov tseem ceeb ntawm cov khoom siv no yog qhov tseem ceeb rau txhua tus neeg ua haujlwm nrog lub zog hluav taws xob. Los ntawm kev ua kom cov khoom siv hluav taws xob thiab RCDs tau teeb tsa thiab saib xyuas kom zoo, peb tuaj yeem tsim kom muaj ib puag ncig muaj kev nyab xeeb dua rau peb tus kheej thiab lwm tus thiab txo qhov kev pheej hmoo ntawm kev phom sij hluav taws xob hauv peb lub tsev thiab chaw ua haujlwm.
