RCCB Breaker: Koj qhov khoom siv kev nyab xeeb tseem ceeb rau kev tiv thaiv hluav taws xob

Kev nyab xeeb hluav taws xob yog qhov qhia tau nyob hauv ib lub tsev lossis chaw ua haujlwm, thiab cov cuab yeej uas yog ib qho yuav tsum tau ua kom muaj kev nyab xeeb yog cov rooj tog hluav taws xob tam sim no. Puas yog nws kev paub txog ntawm cov lus txiav txim siab lossis tsuas yog kev pib ntawm kev kawm txog RCCBs, cov kab lus no yuav siv ib qho ntawm txhua yam txog rccbs thiab vim li cas lawv yog qhov tseem ceeb ntawd.

Dab tsi yog ib qhoRccb?

Tus RCCB breaker lossis residual tam sim no ntaus ntawv yog lub cuab yeej rau kev nyab xeeb rau hluav taws xob tiv thaiv hluav taws xob lossis tsis muaj dej xau. Nws lub luag haujlwm tseem ceeb yog muab cov lus tsis txaus ntseeg tawm tsam qhov ntws ntawm cov hluav taws xob kom nws tuaj yeem kaw lub zog hluav taws xob kom tiv thaiv kev raug mob lossis kev puas tsuaj.

Tsuas yog muab tso, tus ua haujlwm ntawm RCCB yog nyob ntawm qhov hluav taws xob ntau dua los ntawm kev tsis muaj hluav taws xob zoo li los ntawm tib neeg lub cev lossis cov xaim.

RCCB ua haujlwm li cas?

RCCB ua haujlwm ntawm lub hauv paus ntsiab lus ntawm Constchaning piv rau txoj kev tam sim no los ntawm Live (Theem) tus neeg coj thiab tus coj kev nom. Qhov tseeb, ob lub cawv yuav tsum muaj sib npaug hauv kev ua haujlwm. Ntawm qhov tod tes, yog tias muaj kev lom zem-piv txwv, thaum ib tus neeg tuaj cuag nrog cov hlau nyob lossis cov khoom siv hluav taws xob tsis sib xws.

Qhov no yog dab tsi yog txhais tau tias yog cov seem tam sim no. Thaum twg RCCB ntes tau cov seem tam sim no saum toj no cov teeb tsa txwv-feem ntau teeb tsa rau 30mA rau ntawm cov kab ke, piv txwv - nws mus ncig ntawm Circuit Court thiab disconnects lub hwj chim rau qhov Circuit Court. Qhov no tshwm sim yog li ntawd tej zaum ua rau hluav taws xob ua rau hluav taws xob lossis hluav taws yuav tiv thaiv los ntawm kev tshwm sim.

Hom ntawmRCCB RHER

RCCBBBBBBBBBBBS tuaj nyob rau hauv ntau hom ntawv thiaj li kom tau raws cov kuj xav tau thiab siv. Lawv suav nrog:

Hom Ac RCCB: Tsim nyog rau kev siv dav dav, nws tuaj yeem kuaj cov chaw seem ntawm AC.
Yam Ntaus RCCB: Cov hom no tau pom cov khoom seem ntawm AC thiab Pulsating DCS.
Hom B RCCB: Rau cov tshuab nyuaj, nws paub AC, DC, thiab siab dua zaus cov dej ntws.
Hom F RCCB: Tsim los Ntes cov khoom seem hauv cov tshuab nrog cov khoom siv hluav taws xob nyuaj li muaj zog.

Salient yam ntxwv ntawm RCCB cov fais fab

RCCBLES tau pom lawv qhov chaw nyob rau hauv niaj hnub hluav taws xob zes vim yog cov txiaj ntsig ntawm cov cuab yeej hauv averting loj hluav taws xob phom sij. Qee qhov tseem ceeb ntawm RCCBBBBBBBBS yog:

Kev tiv thaiv tiv thaiv hluav taws xob

Kev tiv thaiv tiv thaiv hluav taws xob yog kab tias qhov tseem ceeb tshaj plaws ntawm RCCB. RCCB ua haujlwm tam sim ntawd thaum seem tam sim no tau kuaj thiab txo cov peev txheej ntawm kev raug mob lossis hluav taws xob rau ib tus neeg.

Kev tiv thaiv los ntawm hluav taws kub hluav taws

Hluav taws hluav taws xob feem ntau tshwm sim vim tias muaj qee qhov tsis pom zoo, zoo li kev sib xyaw ua ke lossis kev ua haujlwm ntawm cov khoom siv hluav taws xob. RCCBLs pab cuam tshuam los ntawm kev tiv thaiv tau yooj yim los ntawm kev txiav lub zog hauv cov ntaub ntawv tsis raug.

Overcurrent tiv thaiv

Sib nrug los ntawm kev kuaj pom ntawm cov seem tam sim no, qee cov rccbs kuj muaj kev tiv thaiv dhau los. Qhov no lawv tuaj yeem ua los ntawm kev tawm ntawm Circuit hauv rooj plaub nyob rau hauv cov ntaub ntawv nyob rau hauv cov hluav taws xob tau tshaj qhov txwv tsis pub siv los tuav cov khoom siv thiab hluav ncau los ntawm kev puas tsuaj.

Yooj yim siv

Rccbs tau tsim los nrog kev yooj yim ntawm kev teeb tsa thiab kev saib xyuas hauv lub siab. Cov cuab yeej feem ntau yog kev cog lus thiab haum rau cov hluav taws xob muaj hluav taws xob tsis muaj fuss ntau. Lawv kuj muaj nyob hauv ob peb lub zog faib hluav taws xob, uas tuaj yeem ntsia tau ze ntawm cov khoom thiab / lossis cov cuab yeej siv hluav taws xob uas tsim kom muaj hluav taws xob muaj hluav taws xob lossis ua luam dej.

Tus kheej los kho dua

Hauv qee qhov tshiab rccbs, qhov no yuav yog ib qho ntxiv ntawm qhov twg, nws yuav rov pib dua thiab tso cai rau kev kho hluav taws xob ib zaug cov seem tam sim no rov qab mus rau qhov qub lossis qib muaj kev nyab xeeb.

Vim li cas koj thiaj li xav tau RCCB

Feem ntau cov teb chaws tau ua rau nws yuav tsum tau ua kom nruab RCCBBBBBBBBS nyob rau thaj chaw, kev lag luam, thiab cov tsev lag luam tseem ceeb ntawm kev tiv thaiv tsis muaj kev tiv thaiv tsis muaj.

Rau cov tsev:Nyob rau hauv cov chaw nyob, ib qho RCCB yog rau ntawm qhov chaw kom ntseeg tau tias tsev neeg tseem tsis tuaj txog hluav taws xob hluav taws xob thiab hluav taws kub. Los ntawm kev txuag lub neej tsis muaj txiaj ntsig los tiv thaiv kev sib tsoo nrog cov menyuam yaus ib puag ncig, ib qho RCCB yog ib qho tsis muaj peev xwm yuav tsis muaj kev nyab xeeb rau kev nyab xeeb.
Rau kev lag luam:Tshwj xeeb tshaj plaws ntawm cov chaw ua haujlwm siv cov tshuab ua haujlwm hnyav thiab cov cuab yeej siv hluav taws xob hnyav, cov feem muaj feem ua hluav taws xob yog siab dua. RCCBLs pab tiv thaiv cov neeg ua haujlwm thiab xyuas kom cov hluav taws xob tsis sib xws nyob hauv kev nyab xeeb, ua haujlwm thaum tsis muaj kev kho tsis tsim nyog.
● Rau cov ntawv thov muaj:Cov kev siv hluav taws xob feem ntau muaj cov kev npaj hluav taws xob, txuas nrog cov khoom siv hluav taws xob zoo. Lub installation ntawm rcbbs ntawm cov chaw no yog ua cov ntsiab lus ntawm kev tiv thaiv txuas ntxiv ntawm cov haujlwm thiab txuag cov khoom muaj kev puas tsuaj los ntawm cov hluav taws xob.

Li cas los xaiv txoj cai Rccb

Yuav ua li cas xaiv txoj cai RCCB breaker rau koj cov kev xav tau nyob ntawm ob peb yam. Ntawm no yog dab tsi los xav txog thaum yuav ib:

Kev hnov ​​tau

Qhov rhiab heev ntawm RCCB tau muab rau hauv MilliamPere (MA), thiab rau cov ntawv thov hauv chaw nyob, qhov teeb tsa feem ntau yog 30MA. Qee qhov xwm txheej, tshwj xeeb rau kev lag luam lossis cov ntawv thov pheej hmoo, nws yuav tsim nyog dua siv cov rhiab siab rccbs.

Kev ntsuas tam sim no

Qhov no yog hais txog qhov siab tshaj plaws RCCB muaj peev xwm lis ua ntej tripping. Nco ntsoov tias koj xaiv qhov kev ntsuam xyuas tsim nyog tam sim no rau koj cov hluav taws xob kom tsis txhob muaj qhov tsis tsim nyog.

Ntaus

Raws li tau hais yav tas los, muaj ntau hom RCCBS, txhua tus tsim rau kev sib xyaw hluav taws xob sib txawv. Nco ntsoov tias cov kev xav tau tshwj xeeb ntawm koj kev teeb tsa yog tias koj cov khoom siv hluav taws xob tau yooj yim thiab rhiab.

Overcurrent tiv thaiv

Yog tias koj xav tau RCCB uas tseem tuaj yeem pab tiv thaiv kev tshaj tawm dhau los, tom qab ntawd tuaj yeem muab cov khoom siv uas tuaj yeem muab cov hluav taws xob sib zog tam sim no nrog cov kev tiv thaiv kev tiv thaiv kev tiv thaiv dhau los.

Txhim Kho thiab Txij Nkawm

Nws ib txwm pom zoo kom muaj RCCB ntsia los ntawm cov hluav taws xob tsim nyog. Kev teeb tsa los ntawm cov hluav taws xob tsim nyog kom cov cuab yeej ua haujlwm raws li kev tiv thaiv yuav tsum tau tiv thaiv kev tiv thaiv uas yuav tsum tau ua. RCCBS xav tau kev txij nkawm me ntsis, txawm hais tias nquag ntsuas tau pom zoo kom ntseeg tau tias RCCB cov haujlwm kom raug.

Feem ntau ntawm RCCBs haum nrog lub pob ntsuas kev sim, muab kev ntsuam xyuas kev sib tham ntawm cov cuab yeej los ntawm tus neeg siv seb puas muaj haujlwm ua haujlwm lossis tsis ua. Thaum lub khawm no nias, ua txhaum yog tsim tau thiab RCCB yuav tsum mus ncig tam sim. Nws ua raws li txoj kev coj ua zoo ntawd yuav sim ntsuas RCCB tsawg kawg ib zaug txhua lub hlis kom ntseeg tau tias nws ua haujlwm zoo.

RCCB breaker yog qhov tseem ceeb ntawm cov hluav taws xob uas nws tuaj yeem lees paub qhov chaw tsis muaj kev tiv thaiv hluav taws xob thiab hluav taws. Ua nws yog koj lub tsev, kev lag luam, lossis txawm tias muaj ib qho chaw muaj kev lag luam, ib qho tuaj yeem ua rau muaj kev tiv thaiv lub neej thiab cov khoom ntiag tug yog los ntawm kev teeb tsa ntawm RCCB.

Raws li cov tshuab hluav taws xob tau dhau los ua kom muaj kev nyuaj, thiab cov nqi ua haujlwm tsis zoo, muaj kev ntseeg siab RCCB ua ntau dua thiab tseem ceeb dua. RCCB breaker yog qee yam tsis tseem ceeb hauv kev muab hluav taws xob kev nyab xeeb hauv kev teeb tsa niaj hnub. Ib txwm xa mus rau hluav taws xob uas tuaj yeem pab koj txiav txim siabZoo Tshaj RccbRau koj cov kev xav tau thiab paub tseeb tias koj tau txais cov kauj ruam tsim nyog los tiv thaiv koj tus kheej thiab lwm tus ntawm cov khoom hluav taws xob.
