Hauv kev nyab xeeb ntawm hluav taws xob,cov cuab yeej hluav taws xob seem (RCCBs)ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv tib neeg thiab khoom vaj khoom tsev ntawm kev phom sij hluav taws xob. Cov khoom siv no yog tsim los tiv thaiv kev poob hluav taws xob thiab txo qhov kev pheej hmoo ntawm hluav taws xob los ntawm kev ua txhaum hauv av. Tsab xov xwm no yuav tham txog kev ua haujlwm, qhov tseem ceeb, thiab kev siv ntawm RCCBs kom ntxaws.
Lub tshuab hluav taws xob seem uas ua haujlwm tam sim no (RCCB) yog dab tsi?
Lub tshuab hluav taws xob seem (RCCB) yog ib lub cuab yeej hluav taws xob uas txiav lub voj voog thaum nws pom tias muaj qhov tsis sib npaug ntawm cov xov hluav taws xob uas muaj zog (theem) thiab cov xov hluav taws xob nruab nrab. Qhov tsis sib npaug no yuav tshwm sim los ntawm qhov tsis ua haujlwm, xws li ib tus neeg kov lub xov hluav taws xob uas muaj zog, lossis qhov tsis ua haujlwm hluav taws xob ua rau cov hluav taws xob xau mus rau hauv av. RCCB saib xyuas cov hluav taws xob hauv lub voj voog tas li, thiab yog tias nws pom qhov sib txawv ntawm cov hluav taws xob (feem ntau yog 30 mA rau kev tiv thaiv tus kheej), nws yuav txiav thiab txiav lub zog hluav taws xob hauv milliseconds.
Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab hluav taws xob seem (RCCB) yog dab tsi?
Ib lub tshuab hluav taws xob seem uas ua haujlwm los ntawm lub voj voog hluav taws xob (RCCB) ua haujlwm raws li lub hauv paus ntsiab lus ntawm qhov hluav taws xob sib txawv. Nws muaj ib lub plawv hlau thiab ob lub kauj: ib qho rau cov xov hlau muaj sia thiab ib qho rau cov xov hlau nruab nrab. Raws li qhov xwm txheej ib txwm muaj, qhov hluav taws xob ntws los ntawm ob lub kauj yog sib npaug, thiab cov teb sib nqus uas tsim los ntawm cov kauj yuav tshem tawm ib leeg. Txawm li cas los xij, yog tias muaj qhov hluav taws xob xau, qhov sib npaug no raug cuam tshuam, ua rau muaj qhov sib txawv ntawm lub zog sib nqus. Qhov tsis sib npaug no ua rau RCCB tsoo, txiav lub voj voog thiab tiv thaiv kev phom sij.
Qhov Tseem Ceeb ntawm Cov Khoom Siv Hluav Taws Xob Uas Ua Haujlwm Tam Sim No
Qhov tseem ceeb ntawm cov khoom siv hluav taws xob seem (RCCBs) tsis tuaj yeem tsis quav ntsej. Lawv yog ib txoj kab tiv thaiv tseem ceeb tiv thaiv kev raug hluav taws xob, uas tuaj yeem ua rau raug mob hnyav lossis tuag taus. Raws li cov qauv kev nyab xeeb, ntau lub tsev nyob thiab cov lag luam, tshwj xeeb tshaj yog thaj chaw muaj dej (xws li chav dej thiab chav ua noj), yuav tsum muaj RCCBs. RCCBs tuaj yeem teb sai rau qhov tsis ua haujlwm hluav taws xob, txhim kho kev nyab xeeb ntawm kev teeb tsa hluav taws xob.
Ntxiv mus, cov cuab yeej hluav taws xob seem uas siv hluav taws xob (RCCBs) pab tiv thaiv kom tsis txhob muaj hluav taws xob kub hnyiab. Cov kab hluav taws xob tsis zoo, kev puas tsuaj ntawm cov khoom rwb thaiv tsev, lossis cov hluav taws xob tsis zoo tuaj yeem ua rau kub dhau thiab muaj hluav taws xob tawg, uas tuaj yeem ua rau cov khoom siv hluav taws kub hnyiab. RCCBs tuaj yeem txiav lub voj voog tam sim ntawd thaum muaj teeb meem tshwm sim, yog li ntawd txo qhov kev pheej hmoo ntawm hluav taws thiab tiv thaiv lub neej thiab khoom vaj khoom tsev.
Daim Ntawv Thov ntawm Cov Khoom Siv Hluav Taws Xob Uas Ua Haujlwm Tam Sim No
Cov cuab yeej hluav taws xob seem (RCCBs) siv dav hauv ntau qhov chaw, suav nrog tsev nyob, lag luam, thiab kev lag luam. Hauv cov tsev nyob, lawv feem ntau raug ntsia rau ntawm lub vaj huam sib luag faib khoom loj los tiv thaiv txhua lub voj voog. Hauv cov tsev lag luam, RCCBs yog qhov tseem ceeb rau kev tiv thaiv cov khoom siv thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov neeg siv khoom. Hauv cov chaw ua haujlwm, tshwj xeeb tshaj yog qhov chaw siv tshuab hnyav, RCCBs yog qhov tseem ceeb rau kev tiv thaiv cov neeg ua haujlwm ntawm kev phom sij hluav taws xob.
Tsis tas li ntawd xwb, cov khoom siv hluav taws xob seem uas ua haujlwm los ntawm cov hluav taws xob seem (RCCBs) tuaj yeem siv ua ke nrog lwm cov khoom siv tiv thaiv, xws li cov khoom siv hluav taws xob me me (MCBs) thiab cov khoom tiv thaiv hluav taws xob ntau dhau (SPDs), los tsim kom muaj kev nyab xeeb hluav taws xob zoo. Kev sib xyaw ua ke no tsis yog tsuas yog ua kom paub tseeb tias muaj kev kuaj pom thiab kev tswj hwm cov teeb meem hauv av xwb tab sis kuj daws tau cov teeb meem overloads thiab surges.
Dab tsi ua rau lub RCD breaker ua haujlwm?
Cov voj voog uas muaj ntau dhau, cov dej noo nkag mus, cov xov hlau puas tsuaj, xau av, thiab cov khoom siv tsis zoo yog cov laj thawj tseem ceeb uas ua rau RCD tripping. Kev nkag siab txog cov yam no tuaj yeem pab koj txheeb xyuas thiab daws qhov teeb meem sai sai kom ntseeg tau tias muaj kev nyab xeeb ntawm hluav taws xob hauv koj lub tsev.
Hauv kev xaus lus
Hauv kev xaus lus, cov khoom siv hluav taws xob seem (RCCBs) yog ib qho tseem ceeb ntawm cov txheej txheem kev nyab xeeb hluav taws xob niaj hnub. Lawv ntes thiab teb rau qhov tsis sib npaug ntawm hluav taws xob, ua haujlwm ua cov cuab yeej tseem ceeb rau kev tiv thaiv kev poob hluav taws xob thiab hluav taws xob. Raws li peb lub neej txhua hnub vam khom hluav taws xob ntau zuj zus, kev nkag siab thiab kev siv RCCBs yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb hauv tsev, chaw ua haujlwm, thiab lwm qhov chaw. Kev nqis peev rau hauv RCCBs zoo thiab xyuas kom meej tias lawv tau teeb tsa kom raug muab kev thaj yeeb nyab xeeb thiab tiv thaiv kev poob hluav taws xob tsis tau xav txog.
