Njengoko bekutshiwo ngaphambili, i-RCBO iqinisekisa ukhuseleko kwiintlobo ezimbini zombane.Eyokuqala kwezi mpazamo ngumsinga oshiyekileyo okanye ukuvuza komhlaba.Oku kuyathandalkwenzeka xa kukho ikhefu ngengozi kwisekethe, enokuthi yenzeke ngenxa yeempazamo zocingo okanye iingozi ze-DIY (ezifana nokusika intambo xa usebenzisa i-hedge cutter yombane).Ukuba unikezelo lombane awophukanga, umntu lowo uya kufumana umothuko wombane onokubulala

Olunye uhlobo lwempazamo yombane yi-overcurrent, enokuthi ithathe uhlobo lwe-overload okanye isiphaluka esifutshane, Kwimeko yokuqala.Isekethe iya kulayishwa kakhulu ngezixhobo zombane ezininzi, okukhokelela ekugqithisweni kombane ongaphezulu komthamo wekhebula.Ukujikeleza okufutshane kunokuthi kwenzeke ngenxa yokunganyangeki kwesekethe kunye nokuphindaphinda kwe-amperage ephezulu.Oku kunxulunyaniswa nenqanaba lomngcipheko omkhulu kunokulayisha ngaphezulu

Jonga kwiindidi ze-RCBO ezifumaneka kwiimpawu ezahlukeneyo ezingezantsi.

I-RCBO vs. MCB

I-MCB ayinakukhusela kwiimpazamo zomhlaba, ngelixa i-RCBOs inokukhusela ngokuchasene nombane kunye neempazamo zomhlaba.

Ii-MCBs zijonga ukuhamba kwangoku kunye nokuphazamisa iisekethe ngexesha leesekethe ezimfutshane kunye nokugqithiswa.Ngokwahlukileyo, ii-RCBOs zibeke iliso ekuhambeni kwangoku kumgca kunye nokubuyela kumgca ongathathi hlangothi.Kwakhona, ii-RCBOs zinokuphazamisa isekethe ngexesha lokuvuza komhlaba, isiphaluka esifutshane, kunye ne-overcurrent.

Unokusebenzisa ii-MCBs ukukhusela ii-air conditioners, iisekethe zokukhanyisa, kunye nezinye izixhobo ngaphandle kwezixhobo kunye nezifudumezi ngokudibana ngokuthe ngqo namanzi.Ngokwahlukileyo, ungasebenzisa i-RCBO yokukhusela ukothuka kombane.Ke ngoko, ungayisebenzisa ukuphazamisa amandla, iisokethi zamandla, izifudumezi zamanzi apho unokuba nethuba lokubetha kombane.

Unokukhetha ii-MCBs ngokusekwe kowona mzuzu uphezulu wesekethe yangoku kwaye ulayishe unokuphazamisa ngokukhuselekileyo kunye nejika lokuhamba.Ii-RCBOs ziquka indibaniselwano ye-RCBO kunye ne-MCB.Ungazikhetha ngokusekwe kowona mzuzu uphezulu wesekethe yangoku kunye nomthwalo, kwaye inokukhubaza ijika, iphazamise, kwaye ibonelele ngokuvuza okukhulu ngoku.

I-MCB inokubonelela ngokhuseleko kwiisekethe ezimfutshane kunye ne-overcurrent, ngelixa i-RCBO inokukhusela imisinga yokuvuza komhlaba, iisekethe ezimfutshane kunye ne-overcurrent.

I-RCBO ingcono kuba inokukhusela imisinga yokuvuza komhlaba, iisekethe ezimfutshane, kunye ne-overcurrent, ngelixa i-MCB ibonelela ngokhuseleko kwiisekethe ezimfutshane kunye ne-overcurrent.Kwakhona, i-RCBO inokukhusela izothuso zombane kunye neempazamo zomhlaba, kodwa ii-MCBs zisenokungabi njalo.

Ungayisebenzisa nini i-RCBO?

Unokusebenzisa i-RCBO yokhuseleko ngokuchasene nezothuso zombane.Ngokukodwa, ungayisebenzisa ukuphazamisa iisokethi zamandla kunye ne-heater yamanzi, apho unokufumana ithuba lokutshatyalaliswa kombane.

Igama elithi RCBO limele iResidual Current Breaker enokhuseleko lwangoku.Ii-RCBOs zidibanisa ukhuseleko kwimisinga yokuvuza komhlaba ngokunjalo nakwimisinga (i-overload okanye i-short-circuit).Umsebenzi wabo unokuvakala ngathi we-RCD (Isixhobo esiNgqongileyo sangoku) ngokwemiqathango yokhuseleko olugqithisiweyo kunye nolufutshane, kwaye oko kuyinyaniso.Ke ngoko yintoni umahluko phakathi kwe-RCD kunye ne-RCBO?

I-RCBO yenzelwe ukudibanisa ukusebenza kwe-MCB kunye ne-RCD ukuqinisekisa ukusebenza okukhuselekileyo kweesekethe zombane.Ii-MCDs zisetyenziselwa ukubonelela ngokhuseleko kwi-over-currents kwaye ii-RCD zenziwa ukuze zibone ukuvuza komhlaba.Ngelixa isixhobo se-RCBO sisetyenziselwa ukubonelela ngokhuseleko ngokuchasene nokugcwala, iisekethe ezimfutshane, kunye nemisinga yokuvuza komhlaba.

Injongo yezixhobo zeRCBO kukubonelela ngokhuseleko kwiisekethe zombane ukuze kuqinisekiswe ukuba isekethe yombane isebenza ngokukhuselekileyo.Ukuba i-current ayilingani, yindima ye-RCBO ukuqhawula / ukuphula isiphaluka ukuthintela umonakalo onokwenzeka kunye neengozi kwisekethe yombane okanye kumsebenzisi wokugqibela.

Njengoko igama libonisa, ii-RCBOs ziyilelwe ukukhusela kwiintlobo ezimbini zeempazamo.Iimpazamo ezimbini eziqhelekileyo ezinokuthi zenzeke ngaphakathi kwemisinga yombane kukuvuza koMhlaba kunye ne-Over-Currents.

Ukuvuza komhlaba kwenzeka xa kukho ikhefu ngengozi kwisekethe enokuthi ibangele iingozi ezinjengokothuka kombane.Ukuvuza komhlaba kaninzi kwenzeka ngenxa yofakelo olulambathayo, iingcingo ezingentle okanye imisebenzi ye-DIY.

Kukho iintlobo ezimbini ezahlukeneyo ze-over-current.Ifom yokuqala i-overload eyenzeka xa kukho izicelo zombane ezininzi kakhulu kwisekethe enye.Ukulayisha kakhulu isekethe yombane kwandisa umthamo ocetyiswayo kwaye kunokubangela umonakalo kwisixhobo sombane kunye neenkqubo zamandla ezinokukhokelela kwiingozi ezifana nokutshitshiswa kombane, umlilo, kunye nokudubula.

Ifom yesibini yisekethe emfutshane.Isiphaluka esifutshane senzeke xa kukho uxhulumaniso olungaqhelekanga phakathi kweedibaniso ezimbini zesekethe yombane kwii-voltages ezahlukeneyo.Oku kunokubangela umonakalo kwisekethe kuquka ukufudumala okanye umlilo onokuthi ubekho.Njengoko bekutshiwo ngaphambili, ii-RCD zisetyenziselwa ukukhusela ngokuchasene nokuvuza komhlaba kwaye ii-MCB zisetyenziselwa ukukhusela ngokugqithisileyo.Ngelixa ii-RCBOs ziyilelwe ukukhusela kuzo zombini iindawo ezivuzayo zomhlaba kunye nemisinga engaphezulu.

Ii-RCBO zineenzuzo ezininzi ngokusebenzisa ii-RCD kunye nee-MCBs eziquka oku kulandelayo:

1.RCBOs ziyilwe njengesixhobo "All in One".Isixhobo sibonelela ngokhuseleko lwe-MCB kunye ne-RCD ethetha ukuba akukho mfuneko yokuzithenga ngokwahlukileyo.

I-2.RCBOs ziyakwazi ukuchonga iimpazamo ngaphakathi kwesekethe kwaye ziyakwazi ukuthintela iingozi ezinokuthi zibekho zombane ezifana nokutshitshiswa kombane.

3.I-RCBO iya kuqhekeza ngokuzenzekelayo isiphaluka sombane xa isiphaluka singenakulinganiswa ukunciphisa ukutshatyalaliswa kombane kunye nokuthintela umonakalo kwiibhodi zeeyunithi zabathengi.Ukongeza, ii-RCBOs ziya kukhwela isekethe enye.

4.RCBOs zinexesha elifutshane lokufakela.Nangona kunjalo, kuyacetyiswa ukuba umntu osebenza ngombane onamava afakele i-RCBO ukuqinisekisa ukufakela okugudileyo nokukhuselekileyo

I-5.RCBOs iququzelela uvavanyo olukhuselekileyo kunye nokugcinwa kwezixhobo zombane

6.Isixhobo sisetyenziselwa ukunciphisa ukukhubeka okungafunekiyo.

7.RCBOs zisetyenziselwa ukomeleza ukhuseleko kwisixhobo sombane, umsebenzisi wokugqibela, kunye nepropathi yabo.

I-RCBO yesigaba sesithathu luhlobo olukhethekileyo lwesixhobo sokhuseleko olusetyenziswa kwiinkqubo zombane zesigaba sesithathu, umgangatho kwiindawo zorhwebo kunye nezoshishino.Ezi zixhobo zigcina iingenelo zokhuseleko lwe-RCBO esemgangathweni, enika ukhuseleko kwizothuso zombane ngenxa yokuvuza kwangoku kunye neemeko ezidlulayo ezinokukhokelela kwimililo yombane.Ukongeza, ii-RCBO zezigaba ezithathu ziyilelwe ukujongana nobunzima beenkqubo zamandla zezigaba ezithathu, zibenza zibe yimfuneko ekukhuseleni izixhobo kunye nabasebenzi kwindawo apho zisetyenziswa khona ezo nkqubo.
