Ukhuseleko lwe-AFDD: Isishwankathelo Esipheleleyo
Kwihlabathi lokhuseleko lombane, ukhuseleko lwe-AFDD, okanye ukhuseleko lwe-Arc Fault Device, lube yinxalenye ebalulekileyo ekukhuseleni izakhiwo zokuhlala nezorhwebo kwiingozi zeziphene zombane. Njengoko ubuchwepheshe buqhubela phambili kwaye ukuthembela kwethu kwiinkqubo zombane kukhula, ukuqonda ukhuseleko lwe-AFDD kubalulekile ukuqinisekisa ukhuseleko lombane kunye nokuthobela imigangatho yombane yanamhlanje.
Yintoni ukhuseleko lwe-AFDD?
Izixhobo zokukhusela ze-AFDD zenzelwe ukubona iimpazamo ze-arc kwiisekethe zombane. Iimpazamo ze-arc kukukhupha umbane okungalindelekanga okwenzeka ngenxa yeengcingo ezonakeleyo, uqhagamshelo olukhululekileyo, okanye izixhobo ezingasebenzi kakuhle. Ukuba azilungiswanga ngokukhawuleza, ezi mpazamo zinokubangela ubushushu obugqithisileyo kwaye ekugqibeleni kubekho imililo yombane. Ii-AFDD zenzelwe ukuchonga ezi meko ziyingozi kunye nokunciphisa umbane ngaphambi kokuba kwenzeke umlilo.
Ukubaluleka kokukhuselwa kwe-AFDD
Ukubaluleka kokukhuselwa kwe-AFDD akunakugxininiswa kakhulu. Izifundo ezininzi zibonise ukuba imililo yombane ibangela ipesenti enkulu yemililo yamakhaya, nto leyo ebangela umonakalo kwipropathi, ukwenzakala, kunye nokulahlekelwa bubomi. Ngokufaka ii-AFDD kwiinkqubo zabo zombane, abanini bezindlu kunye namashishini banokunciphisa kakhulu umngcipheko wezo ziganeko.
Ii-AFDD zisebenza kakhulu kwiindawo apho ii-circuit breakers zemveli zingaboneleli ngokhuseleko olufanelekileyo. Umzekelo, kwizakhiwo ezindala, umngcipheko weempazamo ze-arc uphezulu ngenxa yokuguga kweentambo. Ukhuseleko lwe-AFDD lusebenza njengenethi yokhuseleko eyongezelelweyo, ukuqinisekisa ukuba nokuba intambo yonakele, umngcipheko womlilo uyancitshiswa.
Indlela ukhuseleko lwe-AFDD olusebenza ngayo
Ii-AFDD zisebenza ngokujonga rhoqo umsinga ohamba kwisekethe. Zenzelwe ukufumanisa uphawu olulodwa lwempazamo ye-arc eyahlukileyo kwiindlela eziqhelekileyo zokusebenzisa amandla. Xa kufunyenwe impazamo ye-arc, isixhobo sivula ngokukhawuleza isekethe, sisuse umbane kwaye sithintele ingozi yomlilo enokubakho.
Kukho iintlobo ezimbini eziphambili zeempazamo ze-arc ezinokuthi i-AFDD izibone: i-series arcing kunye ne-parallel arcing. I-series arcing yenzeka xa umqhubi ephukile, ngelixa i-parallel arcing yenzeka xa kukho impazamo phakathi kwabaqhubi ababini. Ubuchule be-AFDD bokuchonga zombini ezi ntlobo zeempazamo buyenza ibe nobuchule kwaye isebenze kwiindlela ezahlukeneyo zokusebenza.
Imigangatho yolawulo kunye nokuthobela
Njengoko ulwazi lwabantu ngokhuseleko lombane lusanda, amazwe amaninzi aqalise ukusebenzisa imigaqo eyalela ukusetyenziswa kwezixhobo zokukhusela ze-AFDD kwizakhiwo ezintsha nezihlaziyiweyo. Umzekelo, iNational Electrical Code (NEC) eMelika ikhuphe izikhokelo ezikhuthaza ukufakwa kwe-AFDD kwiindawo ezithile zokuhlala. Ukuthobela le migaqo akupheleli nje ekuphuculeni ukhuseleko, kodwa kuqinisekisa ukuba ikhaya lihlangabezana nemigangatho yamva nje yombane.
Ukufakwa nokugcinwa kokhuseleko lwe-AFDD
Ukufakelwa kwezixhobo zokukhusela ze-AFDD kufuneka kwenziwe rhoqo ngumbane oqeqeshiweyo ukuqinisekisa ukuba zifakwe ngokufanelekileyo kwinkqubo yombane ekhoyo. Indawo ye-AFDD ibaluleke kakhulu; kufuneka ifakwe kwiindawo ezinomngcipheko omkhulu weengxaki zee-arc, njengamagumbi okulala, amagumbi okuhlala kunye neekhitshi.
Kubalulekile nokugcina nokuvavanya i-AFDD rhoqo ukuqinisekisa ukuba isebenza kakuhle. Abanini bezindlu kufuneka bayihlole rhoqo le yunithi baze badibane neengcali ukuze basombulule naziphi na iingxaki okanye ukungasebenzi kakuhle.
OKUKWINTSUSA
Ngamafutshane, ukhuseleko lwe-AFDD luphawu olubalulekileyo kukhuseleko lombane lwanamhlanje. Ngokuqonda ukubaluleka kwalo, ukusebenza kwalo, kunye neemfuno zokuthobela imithetho, abantu banokuthatha amanyathelo asebenzayo okukhusela amakhaya abo kunye namashishini abo kwimiphumo emibi yomlilo wombane. Njengoko ubuchwepheshe buqhubeka nokutshintsha, ukwamkela ubuchwepheshe obutsha obufana ne-AFDD kuya kudlala indima ebalulekileyo ekuphuculeni ukhuseleko kunye nokuthintela iingozi zombane. Ukutyala imali kukhuseleko lwe-AFDD kungaphezulu nje kwemfuneko yomthetho, kukuzibophelela ekuqinisekiseni imeko-bume ekhuselekileyo kuye wonke umntu.
