RCBO yog dab tsi thiab nws ua haujlwm li cas?

RCBOyog cov ntawv luv ntawm "overcurrent residual tam sim no Circuit Court breaker" thiab yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob muaj kev ruaj ntseg uas sib txuas cov haujlwm ntawm MCB (me me Circuit Court breaker) thiab RCD (cov khoom seem tam sim no). Nws muab kev tiv thaiv ob hom hluav taws xob tsis raug: overcurrent thiab residual tam sim no (tseem hu ua to tam sim no).

Kom nkag siab li casRCBOua haujlwm, cia ua ntej sai sai los tshuaj xyuas ob hom kev ua tsis tiav no.

Overcurrent tshwm sim thaum muaj ntau dhau tam sim no hauv Circuit Court, uas tuaj yeem ua rau overheating thiab tej zaum txawm tias hluav taws. Qhov no tuaj yeem tshwm sim rau ntau yam, xws li luv luv Circuit Court, overload, lossis hluav taws xob txhaum. MCBs yog tsim los xyuas thiab cuam tshuam cov overcurrent faults los ntawm tripping lub Circuit Court tam sim ntawd thaum tam sim no tshaj li ib tug predetermined txwv.

Ntawm qhov tod tes, qhov seem tam sim no lossis cov dej xau tshwm sim thaum lub voj voog raug cuam tshuam vim tsis zoo ntawm cov xaim hluav taws xob lossis kev sib tsoo DIY. Piv txwv li, tej zaum koj yuav yuam kev laum los ntawm ib lub cable thaum nruab ib daim duab nuv los yog txiav nws nrog ib tug lawnmower. Hauv qhov no, hluav taws xob tam sim no tuaj yeem nkag mus rau ib puag ncig ib puag ncig, uas ua rau muaj hluav taws xob poob lossis hluav taws. RCDs, tseem hu ua GFCIs (Ground Fault Circuit Interrupters) hauv qee lub tebchaws, tau tsim los kom pom sai sai txawm tias cov dej ntws tawm hauv feeb thiab mus ncig hauv lub voj voog hauv milliseconds kom tsis txhob muaj kev puas tsuaj.

Tam sim no, cia peb saib ze dua ntawm yuav ua li cas RCBO muab cov peev txheej ntawm MCB thiab RCD. RCBO, zoo li MCB, tau nruab rau hauv lub tshuab hluav taws xob lossis cov neeg siv khoom siv. Nws muaj ib tug built-in RCD module uas tsis tu ncua saib xyuas cov tam sim no ntws los ntawm Circuit Court.

Thaum muaj kev cuam tshuam overcurrent tshwm sim, RCBO's MCB tivthaiv kuaj pom cov tam sim no ntau dhau thiab tawm mus rau hauv Circuit Court, yog li cuam tshuam cov khoom siv hluav taws xob thiab tiv thaiv txhua yam kev phom sij cuam tshuam txog overload lossis luv luv Circuit Court. Nyob rau tib lub sijhawm, lub built-in RCD module saib xyuas qhov sib npaug tam sim no ntawm cov xov hlau nyob thiab nruab nrab.

Yog tias muaj qhov seem tam sim no raug kuaj pom (qhia txog qhov ua txhaum cai), RCBO's RCD lub caij tam sim ntawd mus rau hauv Circuit Court, yog li txiav lub hwj chim. Cov lus teb ceev ceev no ua kom ntseeg tau tias tsis muaj hluav taws xob poob siab thiab muaj peev xwm tiv thaiv hluav taws, txo qhov kev pheej hmoo ntawm kev xaim tsis raug lossis kev puas tsuaj ntawm cable.

Nws yog ib qho tsim nyog sau cia tias RCBO muab kev tiv thaiv ib tus neeg hauv Circuit Court, txhais tau hais tias nws tiv thaiv qee qhov hluav taws xob hauv ib lub tsev uas tsis muaj kev ywj pheej ntawm ib leeg, xws li teeb pom kev zoo lossis qhov hluav taws xob. Qhov kev tiv thaiv modular no ua rau pom qhov yuam kev thiab kev cais tawm, txo qis kev cuam tshuam rau lwm cov circuits thaum muaj kev txhaum tshwm sim.

Txhawm rau ua kom tiav, RCBO (overcurrent residual tam sim no Circuit Court breaker) yog ib qho tseem ceeb ntawm hluav taws xob kev nyab xeeb ntaus ntawv uas koom ua ke cov haujlwm ntawm MCB thiab RCD. Nws muaj qhov ua txhaum dhau tam sim no thiab qhov seem tiv thaiv tam sim no ua haujlwm kom muaj kev nyab xeeb ntawm tus kheej thiab tiv thaiv hluav taws kub. RCBOs ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas hluav taws xob kev nyab xeeb hauv tsev, cov tsev lag luam thiab thaj chaw muaj kev lag luam los ntawm kev nrawm nrawm nrawm thaum kuaj pom qhov txhaum.
