UkuqondaI-RCBO: Izinto Ezibalulekile Zokuphepha Kukagesi
Ezweni lokufakwa kukagesi, ukuphepha kubaluleke kakhulu. Esinye sezingxenye ezibalulekile zokuqinisekisa ukuphepha yi-residual current current breaker enesivikelo somsinga ongaphezu kwamandla kagesi, esaziwa kakhulu ngokuthi i-RCBO. Le divayisi idlala indima ebalulekile ekuvikeleni abantu nempahla emaphutheni kagesi, okwenza ibe yingxenye ebalulekile yezinhlelo zikagesi zanamuhla.
Kuyini i-RCBO?
I-RCBO iyinhlanganisela yamadivayisi amabili okuvikela: idivayisi yamanje eseleyo (i-RCD) kanye ne-miniature circuit breaker (i-MCB). Izingxenye ze-RCD zenzelwe ukuthola amaphutha omhlaba, okwenzeka lapho ugesi ugeleza emhlabeni ngendlela engahlosiwe. Amaphutha omhlaba angenzeka ngenxa yokwehluleka kokufakwa kokushisa, umswakama noma ukuthintana ngengozi nezingxenye eziphilayo. Lapho kutholwa iphutha lomhlaba, i-RCD ivula isekethe ukuvimbela ingozi yokushaqeka kukagesi noma umlilo.
Ngakolunye uhlangothi, izingxenye ze-MCB zivikela ezimweni zomsinga ongaphezu kwamandla kagesi, okungabangelwa ukugcwala ngokweqile noma amasekethe amafushane. Ukugcwala ngokweqile kwenzeka lapho amadivayisi amaningi kakhulu exhunywe kwisekethe eyodwa, okubangela umsinga ongaphezu kwamandla awo. Amasekethe amafushane ayenzeka lapho kunokuxhumana okuqondile phakathi kwezintambo ezishisayo nezingathathi hlangothi, okubangela ukwanda okukhulu komsinga ngokuzumayo. Kulezi zimo, i-MCB izokhubeka futhi ivule isekethe, ivimbele ukulimala kwezintambo nezinto zikagesi.
Kungani usebenzisa i-RCBO?
Ukuhlanganisa imisebenzi ye-RCD kanye ne-MCB kudivayisi eyodwa kunikeza izinzuzo eziningana. Okokuqala, kwenza inqubo yokufaka ugesi ibe lula. Esikhundleni sokufaka amadivayisi ahlukene okuvikela iphutha lomhlaba kanye nokusetshenziswa kwamandla angaphezu kwamandla kagesi, i-RCBO inikeza yomibili imisebenzi kuyunithi eyodwa encane. Lokhu akugcini nje ngokusindisa isikhala kuyunithi yabathengi, kodwa futhi kunciphisa isikhathi sokufaka kanye nezindleko.
Okwesibili, ama-RCBO athuthukisa ukuphepha. Uma kwenzeka iphutha likagesi, ama-RCBO azonqamula isekethe ngokushesha, anciphise ingozi yokusha kukagesi nomlilo. Lokhu kubaluleke kakhulu ezindaweni zokuhlala, lapho ukuphepha kwabahlali kuyinto eza kuqala. Ngaphezu kwalokho, ama-RCBO angasetshenziswa ezinhlotsheni ezahlukene zokusebenza, kusukela ekuxhunyweni kwezintambo zasekhaya kuya ekufakweni kwezentengiselwano nezimboni, okwenza kube lula futhi kuhambisane nezimo.
Ukukhetha i-RCBO efanele
Uma ukhetha i-RCBO, kufanele kucatshangelwe izici eziningana. Esokuqala isilinganiso samanje, okufanele sihambisane nezidingo zomthwalo wesekethe. Izilinganiso zamanje ezivamile zifaka phakathi i-6A, 10A, 16A, 20A kanye ne-32A. Kubalulekile ukukhetha i-RCBO engakwazi ukusingatha umthwalo olindelekile ngaphandle kokukhubeka ngokungadingekile.
Esinye isici esibalulekile isilinganiso samanje esisele, esivame ukuvezwa ngama-milliamperes (mA). Izilinganiso ezijwayelekile zifaka phakathi ama-30mA okuvikela umuntu kanye nama-100mA noma ama-300mA okuvikela imishini. Ezinhlelweni zokuhlala, isilinganiso sama-30mA sivame ukunconywa ukuvimbela ukushaqeka kukagesi.
Kubalulekile futhi ukucabangela uhlobo lwe-RCBO. Kunezinhlobo eziningana ongakhetha kuzo, njenge-AC, A, kanye ne-B, ngayinye eyenzelwe uhlelo oluthile. Uhlobo lwe-AC lufanelekela izifunda zamanje ezishintshanayo, kanti uhlobo lwe-A lungathola i-DC eshayayo, okwenza kube kuhle kakhulu kumasekethe anamadivayisi kagesi. Uhlobo lwe-B lusetshenziselwa izifunda ezingaba ne-DC ebushelelezi, njengalezo ezifakwayo ngamandla elanga.
Ngokufigqiwe
Ekuphetheni, ama-RCBO ayithuluzi elibalulekile ezinhlelweni zikagesi zesimanje, ahlinzeka ngokuvikelwa okubili emaphutheni omhlaba kanye nasezimweni zomsinga ongaphezu kwamandla. Ukwakheka kwawo okufushane, ukufakwa okulula, kanye nezici zokuphepha ezithuthukisiwe kuwenza abe yisinqumo esiphezulu kochwepheshe bakagesi kanye nabaninikhaya. Njengoba amazinga okuphepha kagesi eqhubeka nokuguquka, ukubaluleka kokufaka ama-RCBO emishinini kagesi akunakuphikiswana ngakho. Ngokuqonda nokusebenzisa lesi sici esibalulekile, singaqinisekisa indawo ephephile yawo wonke umuntu.
