Dab tsi yog RCBO thiab nws ua haujlwm li cas?

RcboYog cov lus luv ntawm "overcurrent residlual breaker tam sim no cov khoom siv hluav taws xob" thiab yog qhov hluav taws xob muaj txiaj ntsig uas sib xyaw ua ke ntawm cov khoom siv hluav taws xob) thiab ib qho khoom siv hluav taws xob tsawg). Nws muab kev tiv thaiv ob hom hluav taws xob ua txhaum: overcurrent thiab seem tam sim no (tseem hu ua toast tam sim no).

Kom nkag siab li casRcboUa haujlwm, cia thawj zaug saib xyuas ob hom kev ua tsis tiav no.

Overcurrent tshwm sim thaum ntau tam sim no ntws hauv Circuit Court, uas tuaj yeem ua rau muaj kev kub ntxhov thiab tej zaum txawm tias hluav taws. Qhov no tuaj yeem tshwm sim rau ntau qhov laj thawj, xws li lub suab luv, Circuit Couple overload, lossis hluav taws xob ua txhaum. MCBS tau tsim los tshawb xyuas kom pom thiab cuam tshuam cov kev ua txhaum loj los ntawm tripping lub Circuit Court tam sim ntawd thaum lub sijhawm txwv tsis pub dhau los.

Ntawm qhov tod tes, Residual tam sim no lossis kev yoo tshwm sim thaum lub voj voos yog cuam tshuam rau kev sib tsoo vim tsis zoo siv los yog diy kev huam yuaj. Piv txwv li, koj yuav txav mus laum los ntawm ib qho cable thaum txhim kho ib daim duab nuv lossis txiav nws nrog cov kws lij choj. Hauv qhov no, hluav taws xob tam sim no tuaj yeem ua rau ib puag ncig ib puag ncig, muaj peev xwm ua rau hluav taws xob hluav taws xob lossis hluav taws. RCDs, tseem hu ua GFCIS (av yuam kev sib cuam tshuam) hauv qee lub tebchaws, tau tsim kom nrawm nrawm thiab mus ncig ua si hauv Milliseconds los tiv thaiv ib qho kev phom sij.

Tam sim no, cia peb mus saib ze npaum li cas Rcbo ua ke ntawm lub peev xwm ntawm MCB thiab RCD. RCB, zoo li MCB, yog ntsia rau hauv lub tshuab hloov chaw lossis cov neeg siv khoom. Nws muaj cov qauv RCD uas ua rau RCD uas tsis tu ncua tau ntws los ntawm Circuit Court.

Thaum ib tug overcurrens yuam kev tshwm sim, RCBO tus MCB tivthaiv kuaj pom cov hluav taws xob ntau dhau ntawm kev phom sij thiab kev phom sij ntsig txog kev tshaj lij lossis luv Circuit Court. Nyob rau tib lub sijhawm, lub built-in RCD module saib cov nyiaj tshuav tam sim no ntawm cov xov tooj thiab nruab nrab.

Yog kuaj pom tam sim no (qhia tau tias muaj kev txhaum cai ( Kev teb cov lus nrawm no ua kom cov hluav taws xob tsis raug zam thiab hluav taws kub tau tiv thaiv, txo qhov kev pheej hmoo ntawm kev phom sij lossis kev puas tsuaj cable.

Nws muaj nqis ceeb toom tias RCBO muab kev tiv thaiv ib leeg, txhais tau tias nws tiv thaiv tshwj xeeb circuits hauv ib lub tsev uas ywj siab ntawm kev sib tw lossis cov khoom nruab nrab. Cov modular kev tiv thaiv no ua rau muaj kev txhaum yuam kev thiab cais tawm, txo qhov cuam tshuam rau lwm cov kev sib txawv thaum muaj kev txhaum tshwm sim.

Txhawm rau kom suav, RCBO (overcurrent residlual breaker tam sim no yog qhov khoom siv hluav taws xob tseem ceeb uas sib xyaw ua ke ntawm cov haujlwm ntawm cov haujlwm ntawm MCB thiab RCD. Nws tau dhau-tam sim no txhaum thiab Residual kev tiv thaiv tam sim no los xyuas kom tus kheej kev nyab xeeb thiab tiv thaiv kev phom sij ntawm kev nyab xeeb. Rcbos ua si lub luag haujlwm tseem ceeb hauv kev tswj hwm hluav taws xob hauv tsev, lag luam vaj tse thiab kev lag luam ib puag ncig los ntawm kev sib txig raug ntes sai sai thaum muaj kev txhaum.
