UkuqondaI-RCBOIzinto Ezibalulekileyo Zokhuseleko Lombane
Kwihlabathi lokufakelwa kombane, ukhuseleko lubaluleke kakhulu. Enye yezinto ezibalulekileyo ukuqinisekisa ukhuseleko yi-residual current breaker enokhuselo olugqithisileyo, eyaziwa ngokuba yi-RCBO. Esi sixhobo sidlala indima ebalulekileyo ekukhuseleni abantu kunye nempahla kwiimpazamo zombane, nto leyo eyenza ukuba sibe yinxalenye ebalulekileyo yeenkqubo zombane zanamhlanje.
Yintoni i-RCBO?
I-RCBO yindibaniselwano yezixhobo ezimbini zokukhusela: isixhobo samandla asele (RCD) kunye ne-miniature circuit breaker (MCB). Izixhobo ze-RCD zenzelwe ukubona iimpazamo zomhlaba, ezenzeka xa amandla ageleza emhlabeni ngendlela engalindelekanga. Iimpazamo zomhlaba zinokwenzeka ngenxa yokusilela kokufakwa kwezinto, ukufuma okanye ukudibana ngengozi neendawo eziphilayo. Xa kufunyenwe iimpazamo zomhlaba, i-RCD ivula isekethe ukuthintela umngcipheko wokutshayiswa ngumbane okanye umlilo.
Kwelinye icala, izinto ze-MCB zikhusela kwiimeko zomsinga ogqithisileyo, ezinokubangelwa kukugqithisa okanye iisekethe ezimfutshane. Ukugqithisa kwenzeka xa izixhobo ezininzi ziqhagamshelwe kwisekethe enye, nto leyo ebangela ukuba kubekho umsinga ongaphezulu kunokuba unokusingatha ngokukhuselekileyo. Iisekethe ezimfutshane zenzeka xa kukho unxibelelwano oluthe ngqo phakathi kweentambo ezishushu nezingathathi cala, nto leyo ebangela ukunyuka okukhulu komsinga ngequbuliso. Kwezi meko, i-MCB iya kukhubeka ize ivule isekethe, ithintele ukonakala kweentambo nezixhobo.
Kutheni usebenzisa i-RCBO?
Ukudibanisa imisebenzi ye-RCD kunye ne-MCB kwisixhobo esinye kunika iingenelo ezininzi. Okokuqala, kwenza kube lula inkqubo yokufaka umbane. Endaweni yokufaka izixhobo ezahlukeneyo zokukhusela isiphene somhlaba kunye nokukhusela umbane ogqithisileyo, i-RCBO ibonelela ngemisebenzi yomibini kwiyunithi enye encinci. Oku akugcini nje ngokugcina indawo kwiyunithi yabathengi, kodwa kunciphisa nexesha kunye neendleko zokufaka.
Okwesibini, ii-RCBO ziphucula ukhuseleko. Kwimeko yempazamo yombane, ii-RCBO ziya kuyiqhawula ngokukhawuleza isekethe, zinciphise umngcipheko wokutsha kombane. Oku kubaluleke kakhulu kwiindawo zokuhlala, apho ukhuseleko lwabakhweli lubaluleke kakhulu. Ukongeza, ii-RCBO zingasetyenziswa kwiindlela ezahlukeneyo zokusebenza, ukusuka kwiintambo zasekhaya ukuya kwiindawo zorhwebo nezemizi-mveliso, nto leyo ezenza zibe nobuchule kwaye zikwazi ukuguquguquka.
Ukukhetha i-RCBO efanelekileyo
Xa ukhetha i-RCBO, kufuneka kuqwalaselwe izinto ezininzi. Eyokuqala luvavanyo lwangoku, olufanele luhambelane neemfuno zomthwalo wesekethe. Uvavanyo lwangoku oluqhelekileyo luquka i-6A, 10A, 16A, 20A kunye ne-32A. Kubalulekile ukukhetha i-RCBO enokusingatha umthwalo olindelekileyo ngaphandle kokukhubeka ngokungeyomfuneko.
Enye into ebalulekileyo luvavanyo lwangoku olushiyekileyo, oludla ngokubonakaliswa ngee-milliamperes (mA). Uvavanyo oluqhelekileyo luquka i-30mA yokhuseleko lomntu kunye ne-100mA okanye i-300mA yokhuseleko lwezixhobo. Kwizicelo zokuhlala, uvavanyo lwe-30mA luhlala lucetyiswa ukuthintela ukutshayiswa ngumbane.
Kubalulekile nokuqwalasela uhlobo lwe-RCBO. Kukho iintlobo ezahlukeneyo onokukhetha kuzo, ezifana ne-AC, A, kunye ne-B, nganye yenzelwe usetyenziso oluthile. Uhlobo lwe-AC lufanelekile kwiisekethe zamandla ezitshintshanayo, ngelixa uhlobo lwe-A lunokubhaqa i-DC ebethayo, nto leyo eyenza ukuba ifaneleke kwiisekethe ezinezixhobo ze-elektroniki. Uhlobo lwe-B lusetyenziselwa iisekethe ezinokuba ne-DC egudileyo, njengalezo ezifakelwa amandla elanga.
Isishwankathelo
Ukuqukumbela, ii-RCBO zizixhobo ezibalulekileyo kwiinkqubo zombane zanamhlanje, ezibonelela ngokhuseleko oluphindwe kabini kwiimeko zombane ezingalunganga kunye nombane ogqithisileyo. Uyilo lwazo oluncinci, ukufakwa okulula, kunye neempawu zokhuseleko eziphuculweyo zenza ukuba zibe lolona khetho luphezulu koosombane kunye nabanini bezindlu. Njengoko imigangatho yokhuseleko lombane iqhubeka nokutshintsha, ukubaluleka kokufaka ii-RCBO kwizixhobo zombane akunakugxininiswa kakhulu. Ngokuqonda nokusebenzisa eli candelo libalulekileyo, sinokuqinisekisa ukuba kukho indawo ekhuselekileyo kuwo wonke umntu.
