Phakathi kweentlobo ezahlukeneyo ze-RCCB ezikhoyo kwimarike, ii-Type B RCCBs zihlukile ngenxa yeempawu zazo ezizodwa kunye nokusetyenziswa kwazo. Eli nqaku liza kujonga iimpawu, iingenelo, kunye nokusetyenziswa kwe-Type B RCCBs, linike ukuqonda okubanzi kwale nxalenye ibalulekileyo yombane.

Yintoni i-Type B RCCB?

Ii-RCCB zohlobo lwe-AB, okanye ii-Type B residual current breakers, zenzelwe ukubona nokuphazamisa ii-circuits ezineempazamo. Ngokungafaniyo nee-RCCB eziqhelekileyo, ezibona ukuvuza kwe-AC (AC) ngokuyintloko, ii-RCCB zohlobo lwe-B zinokubona ukuvuza kwe-AC kunye ne-pulsating direct current (DC). Oku kuzenza zifaneleke ngakumbi kwizicelo ezibandakanya amandla avuselelekayo, njengeenkqubo ze-solar photovoltaic (PV), apho ukuvuza kwe-DC kunokwenzeka khona.

Iimpawu eziphambili ze-Type B RCCB

1. Amandla okuFumana okuBini: Eyona nto iphawulekayo kwii-RCCB zohlobo B kukukwazi kwazo ukubona zombini ii-AC kunye nee-DC residual currents. Olu buchule bokuFumana okuBini luqinisekisa ukuba naluphi na uhlobo lomsinga wokuvuza lunokuchongwa kwaye lulungiswe ngokukhawuleza.

2. Uvakalelo Oluphezulu: Ii-RCCB zohlobo B zenzelwe ukuba zibe novakalelo oluphezulu, zihlala zilinganiswe kwi-30 mA yokuzikhusela komntu kunye ne-300 mA yokukhusela izixhobo. Olu vakalelo lubalulekile ekuthinteleni ukutshayiswa ngumbane kunye nokunciphisa umngcipheko wemililo yombane.

3. Ukusetyenziswa Okubanzi: Ezi RCCB azipheleli nje ekusetyenzisweni kwezindlu kodwa zikwafanelekile nakwiindawo zorhwebo nakwimizi-mveliso. Ubuchule bazo bokuphatha umbane weDC buzenza zilungele izithuthi zombane, iinkqubo zokugcina amandla ebhetri, kunye nezinye izixhobo ezisebenza ngeDC.

4. Imigangatho ehambelanayo**: Ii-RCCB zohlobo B ziyahambelana nemigangatho yokhuseleko yamazwe ngamazwe, ziqinisekisa ukuba ziyahlangabezana neemfuno ezifunekayo zokufakelwa kombane. Oku kuthotyelwa kubalulekile ekuqinisekiseni ukhuseleko kunye nokuthembeka kweenkqubo zombane.

Iingenelo zokusebenzisa i-Type B RCCB

1. Ukhuseleko Oluphuculweyo: Inzuzo ephambili yokusebenzisa i-Type B residual current circuit breaker (RCCB) kukhuseleko oluphuculweyo olubonelela ngalo. Ngokubona imisinga yokuvuza ye-AC kunye ne-DC, ezi zixhobo zinciphisa kakhulu umngcipheko wokutshayiswa ngumbane kunye nemililo yombane, zikhusela ubomi kunye nepropathi.

2. Ukhuseleko lweZixhobo eziNgcono: Kwiindawo apho kusetyenziswa izixhobo ze-elektroniki ezibuthathaka, ezinje ngeziko ledatha okanye iilebhu, ii-RCCB zohlobo B zibonelela ngokhuseleko olongezelelweyo. Zinceda ekuthinteleni umonakalo kwizixhobo ezibangelwa ziimpazamo zombane, ziqinisekisa ukusebenza okungaphazanyiswa.

3. Ukuhlanganiswa neeNkqubo zaMandla aHlaziyiweyo: Njengoko ihlabathi litshintshela kumandla avuselelekayo, imfuno yee-Type B residual current breakers iyakhula. Zikwazi ukuphatha i-direct current, ii-Type B residual current breakers zibalulekile kwiinkqubo ze-solar photovoltaic kunye nezinye izicelo zamandla avuselelekayo, zinceda ukudibanisa ezi teknoloji ngokukhuselekileyo kwigridi.

4. Isisombululo esingabizi kakhulu: Nangona ixabiso lokuqala le-RCCB yohlobo B linokuba phezulu kune-RCCB eqhelekileyo, amandla ayo okubonelela ngokhuseleko olupheleleyo anokubangela ukonga iindleko ixesha elide. Ngokuthintela ukungasebenzi kakuhle kombane kunye nomonakalo onokubakho, i-RCCB yohlobo B inokunciphisa iindleko zokugcina nokwandisa ubomi benkqubo yakho yombane.

Kufuphi

Ngamafutshane, ii-Type B residual current breakers (RCCBs) ziyinxalenye ebalulekileyo yeenkqubo zokhuseleko lombane zanamhlanje. Amandla azo akhethekileyo okubona zombini ii-AC kunye ne-DC leaking currents azenza zibe luncedo kakhulu kwiindlela ezahlukeneyo zokusebenza, ingakumbi kwicandelo lamandla ahlaziyekayo. Ngokutyala imali kwi-Type B residual current current circuit breaker (RCCB), abantu kunye namashishini banokuphucula ukhuseleko, bakhusele izixhobo ezibuthathaka, kwaye baqinisekise ukuthotyelwa kwemigangatho yombane. Njengoko ubuchwepheshe buqhubeka buhambela phambili, ukubaluleka kwee-Type B residual current current circuit breakers (RCCBs) ekukhuseleni izixhobo zombane kuya kuqhubeka kukhula.
