I-Residual current circuit breaker with over-current-current (RCBO), ngokwenene luhlobo lwe-circuit breaker kunye nomsebenzi wokukhusela ukuvuza. I-RCBO inomsebenzi wokukhusela ekuvuzeni, ukutshitshiswa kombane, ukugcwala kunye nesekethe emfutshane. I-RCBO inokuthintela ukwenzeka kweengozi zokothuka kombane kwaye ibe nesiphumo esicacileyo sokuphepha iingozi zomlilo ezibangelwa kukuvuza kombane. Ii-RCBOs zifakwe kwiibhokisi zethu zokuhambisa zamakhaya ukuze kuqinisekiswe ukhuseleko lomntu. I-RCBO luhlobo lwe-breaker oludibanisa ukusebenza kwe-MCB kunye ne-RCD kwi-breaker enye. I-RCBOs inokuza kwipali ye-1, i-1 + ingathathi hlangothi, iipali ezimbini okanye iipali ze-4 kunye ne-amp rating ukusuka kwi-6A ukuya kwi-100 A, i-curve ye-B okanye i-C, Ukuqhawula amandla 6K A okanye i-10K A, uhlobo lwe-RCD A, A & AC.
Kufuneka usebenzise i-RCBO ngezizathu ezifanayo esicebisa ngazo i-RCB – ukukusindisa ekubulaweni ngombane ngempazamo kwaye uthintele ukutsha kombane. I-RCBO inazo zonke iimpawu ze-RCD ene-detector edlulayo.
I-RCD luhlobo lwe-circuit breaker enokuthi ivule ngokuzenzekelayo i-breaker xa kukho impazamo yomhlaba. Esi saphuli senzelwe ukukhusela imingcipheko yombane ngengozi kunye nomlilo obangelwa ziziphoso zomhlaba. AbaSebenzi boMbane baphinda babize i-RCD (i-Residual Current Device) kunye ne-RCCB (I-Residual Current Circuit Breaker) Olu hlobo lwe-breaker luhlala lune-push-button yokuvavanya i-breaker. Unokukhetha kwiipali ezi-2 okanye ezi-4, ukukala kwe-Amp ukusuka kwi-25 A ukuya kwi-100 A, i-curve B, Uhlobo lwe-A okanye i-AC kunye ne-mA ukusuka kwi-30 ukuya kwi-100 mA.
Ngokufanelekileyo, kuya kuba kuhle ukusebenzisa olu hlobo lwe-breaker ukukhusela imililo yengozi kunye nombane. Nawuphi na umsinga odlula emntwini obaluleke ngaphezu kwe-30 mA unokuqhuba intliziyo kwi-fibrillation ye-ventricular (okanye ukuphosa isingqi sentliziyo)-oyena nobangela uqhelekileyo wokufa ngenxa yokothuka kombane. I-RCD imisa okwangoku ngaphakathi kwe-25 ukuya kwi-40 milliseconds ngaphambi kokuba ukutshatyalaliswa kombane kwenzeke. Ngokwahlukileyo, abaphuli beesekethe eziqhelekileyo ezifana ne-MCB / MCCB (i-Miniature Circuit Breaker) okanye i-fuses iphuka kuphela xa i-current in circuit igqithise (enokuthi ibe ngamawaka amaxesha okuvuza ngoku i-RCD ephendulayo). Ukuvuza okuncinci kwangoku okuhamba emzimbeni womntu kunokwanela ukukubulala. Nangona kunjalo, ngekhe inyuse inani elipheleleyo langoku ngokwaneleyo kwifuse okanye ukulayisha ngaphezulu i-breaker circuit kwaye ingakhawulezi ngokwaneleyo ukugcina ubomi bakho.
Umahluko ophambili phakathi kwezi ziqhekeza zombini zesekethe kukuba i-RCBO ixhotyiswe nge-detector overcurrent. Ngeli xesha, unokucinga malunga nokuba kutheni bezithengisa ngokwahlukeneyo ukuba kukho umahluko omnye ophambili phakathi kwabo? Kutheni ungathengisi kuphela uhlobo emarikeni? Ukuba ukhetha ukusebenzisa i-RCBO okanye i-RCD kuxhomekeke kuhlobo lofakelo kunye nohlahlo lwabiwo-mali. Umzekelo, xa kukho ukuvuza komhlaba kwibhokisi yokuhambisa kusetyenziswa zonke i-RCBO breakers, kuphela i-breaker ene-faulty switch iya kucima. Nangona kunjalo, olu hlobo lweendleko zokumisela luphezulu kunokusebenzisa ii-RCD's. Ukuba uhlahlo lwabiwo-mali ngumba, ungaqwalasela ezintathu kwezine ze-MCB phantsi kwesixhobo esinye esishiyekileyo sangoku. Ungayisebenzisa kwizicelo ezikhethekileyo ezifana nejacuzzi okanye ufakelo lwebhabhu eshushu. Olu fakelo lufuna ngokukhawuleza kunye nokusebenza okuncinci okwangoku, ngokubanzi i-10mA. Ekugqibeleni, nayiphi na i-breaker ofuna ukuyisebenzisa ixhomekeke kuyilo lwakho lwebhodi yokutshintshela kunye nohlahlo lwabiwo-mali. Nangona kunjalo, ukuba uza kuyila okanye uphucule ibhodi yokutshintsha ukuze uhlale kulawulo kwaye uqinisekise ukhuseleko lombane olululo kuzo zombini izixhobo kunye nobomi bomntu, qiniseka ukuba unxibelelana nengcali yombane ethembekileyo.
I-AFDD yi-Arc Fault Detection Device kwaye yenzelwe ukufumanisa ubukho bee-arcs zombane ezinobungozi kunye nokuqhawula isiphaluka esichaphazelekayo. Izixhobo zokujonga i-Arc Fault zisebenza zisebenzisa itekhnoloji ye-microprocessor ukuhlalutya i-waveform yombane. Babona nayiphi na imisayino engaqhelekanga eya kubonisa i-arc kwisekethe. I-AFDD iya kuphelisa ngokukhawuleza amandla kwisiphaluka esichaphazelekayo ngokufanelekileyo ukukhusela umlilo. Zinovakalelo kakhulu kwii-arcs kunezixhobo eziqhelekileyo zokukhusela iisekethe ezifana ne-MCBs & RBCOs.
