FAQ

Q1
RCBO yog dab tsi?

Qhov seem tam sim no Circuit Court breaker nrog kev tiv thaiv dhau tam sim no (RCBO), yog qhov tseeb ntawm cov hluav taws xob hluav taws xob uas muaj kev tiv thaiv tawm.RCBO muaj kev tiv thaiv kev ua haujlwm tawm tsam, hluav taws xob poob siab, overload thiab luv Circuit Court.RCBO tuaj yeem tiv thaiv qhov tshwm sim ntawm hluav taws xob poob siab thiab muaj qhov pom tseeb kom tsis txhob muaj hluav taws kub hnyiab los ntawm hluav taws xob.RCBOs tau nruab rau hauv peb lub thawv faib khoom siv hauv tsev kom ntseeg tau tias tib neeg muaj kev nyab xeeb ntawm tus kheej.Ib qho RCBO yog ib hom kev tawg uas sib txuas ua ke ntawm MCB thiab RCD kev ua haujlwm hauv ib qho kev tawg.RCBOs tuaj yeem tuaj hauv 1 ncej, 1 + nruab nrab, ob tug ncej lossis 4 ncej nrog rau kev ntsuas amp ntawm 6A txog 100 A, tripping nkhaus B lossis C, tawg muaj peev xwm 6K A lossis 10K A, RCD hom A, A & AC.
Q2
Vim li cas thiaj siv RCBO?

Koj yuav tsum siv RCBO rau tib lub laj thawj peb pom zoo RCB - txhawm rau cawm koj ntawm kev sib tsoo hluav taws xob thiab tiv thaiv hluav taws xob hluav taws xob.Ib qho RCBO muaj tag nrho cov txiaj ntsig ntawm RCD nrog lub ntsuas hluav taws xob overcurrent.
Q3
RCD / RCCB yog dab tsi?

Ib qho RCD yog hom hluav taws xob hluav taws xob uas tuaj yeem qhib lub tshuab hluav taws xob thaum lub ntiaj teb ua txhaum.Lub breaker no yog tsim los tiv thaiv cov kev pheej hmoo ntawm kev sib tsoo hluav taws xob thiab hluav taws kub los ntawm lub ntiaj teb ua txhaum.Cov hluav taws xob tseem hu ua RCD (Residual Current Device) thiab RCCB (Residual Current Circuit Breaker) Hom breaker no ib txwm muaj lub laub-khawm rau qhov ntsuas hluav taws xob.Koj tuaj yeem xaiv los ntawm 2 lossis 4 tus ncej, Amp ntsuas ntawm 25 A txog 100 A, tripping nkhaus B, Hom A lossis AC thiab mA ntsuas ntawm 30 txog 100 mA.
Q4
Vim li cas Koj Yuav Tsum Siv RCD?

Qhov zoo tshaj plaws, nws yuav yog qhov zoo tshaj plaws los siv hom kev tawg no los tiv thaiv hluav taws kub thiab hluav taws xob.Txhua qhov tam sim no los ntawm ib tus neeg tseem ceeb tshaj 30 mA tuaj yeem tsav lub plawv mus rau hauv ventricular fibrillation (los yog cuam tshuam lub plawv dhia tawm) - feem ntau ua rau tuag los ntawm hluav taws xob poob siab.Ib qho RCD nres qhov tam sim no li ntawm 25 mus rau 40 milliseconds ua ntej muaj hluav taws xob poob.Los ntawm qhov sib txawv, cov khoom siv hluav taws xob zoo xws li MCB / MCCB (Miniature Circuit Breaker) lossis fuses tawg tsuas yog thaum tam sim no hauv Circuit Court dhau lawm (uas tuaj yeem ua ntau txhiab zaus cov xau tam sim no RCD teb rau).Ib qho me me tam sim no coursing los ntawm tib neeg lub cev tuaj yeem txaus los tua koj.Tseem, tej zaum nws yuav tsis ua kom tag nrho tam sim no txaus rau lub fuse lossis overload lub Circuit Court breaker thiab tsis ceev txaus los cawm koj txoj sia.
Q5
Qhov txawv ntawm RCBO, RCD thiab RCCB yog dab tsi?

Qhov sib txawv tseem ceeb ntawm ob qho tib si Circuit Court breakers yog tias RCBO yog nruab nrog lub ntsuas hluav taws xob overcurrent.Nyob rau ntawm no, tej zaum koj yuav xav txog vim li cas lawv ua lag luam sib txawv yog tias zoo li tsuas muaj qhov sib txawv ntawm lawv?Vim li cas ho tsis muag tsuas yog hom hauv khw?Txawm hais tias koj xaiv siv RCBO lossis RCD nyob ntawm hom kev teeb tsa thiab pob nyiaj siv.Piv txwv li, thaum muaj lub ntiaj teb xau hauv lub thawv xa khoom siv tag nrho RCBO breakers, tsuas yog lub breaker nrog lub faulty hloov mus.Txawm li cas los xij, hom kev teeb tsa tus nqi no siab dua li siv RCD's.Yog tias pob nyiaj siv yog ib qho teeb meem, koj tuaj yeem teeb tsa peb ntawm plaub MCB nyob rau hauv ib qho khoom siv tam sim no.Koj tuaj yeem siv nws rau cov ntawv tshwj xeeb xws li lub jacuzzi lossis kub kub installation.Cov kev teeb tsa no yuav tsum tau ua kom sai thiab tsawg dua tam sim no, feem ntau 10mA.Thaum kawg, qhov twg los xij koj xav siv yog nyob ntawm koj tus qauv tsim thiab pob nyiaj siv.Txawm li cas los xij, yog tias koj tab tom yuav tsim lossis hloov kho koj lub switchboard kom nyob twj ywm hauv kev tswj hwm thiab ua kom muaj kev tiv thaiv hluav taws xob zoo tshaj plaws rau cov cuab yeej cuab tam thiab tib neeg lub neej, nco ntsoov tiv tauj nrog tus kws tshaj lij hluav taws xob txhim khu kev qha.
Q6
AFDD yog dab tsi?

AFDD yog Arc Fault Detection Device thiab nws yog tsim los xyuas kom muaj cov hluav taws xob txaus ntshai arcs thiab disconnect lub Circuit Court cuam tshuam.Arc Fault Detection Devices ua haujlwm siv microprocessor thev naus laus zis los tshuaj xyuas cov qauv ntawm cov hluav taws xob.Lawv ntes ib qho kev kos npe txawv txawv uas yuav qhia tau tias ib qho arc ntawm lub voj voog.AFDD yuav tam sim ntawd txiav lub hwj chim rau qhov cuam tshuam Circuit Court zoo tiv thaiv hluav taws.Lawv muaj txiaj ntsig zoo rau arcs dua li cov khoom siv tiv thaiv hluav taws xob xws li MCBs & RBCOs.
