Ziziphi ii-RCBOs kwaye zahluke njani kwii-RCDs?

Ukuba usebenza ngezixhobo zombane okanye kushishino lokwakha, usenokuba uye wadibana nekotaI-RCBO.Kodwa zithini kanye kanye ii-RCBOs, kwaye zahluke njani kwii-RCDs?Kule bhlog, siza kuphonononga imisebenzi ye-RCBOs kwaye siyithelekise nee-RCDs ukukunceda uqonde iindima zabo ezizodwa kukhuseleko lombane.

Igama elithi RCBO limele iResidual Current Breaker enokhuseleko lwangoku.Ii-RCBOs zizixhobo ezidibanisa ukhuseleko kwimisinga yokuvuza komhlaba ngokunjalo nakwimisinga, njengomthwalo omninzi okanye i-short-circuit.Oku kuthetha ukuba ii-RCBOs zibonelela ngokhuseleko olumbini, nto leyo ezenza zibe yinxalenye ebalulekileyo kwiinkqubo zokhuseleko lombane.

Xa uthi krwada, umsebenzi we-I-RCBOinokuvakala ifana ne-RCD (IsiXhobo esiSishiyekileyo sangoku), njengoko zombini zibonelela ngokhuseleko kwi-overcurrent kunye ne-short-circuit.Nangona kunjalo, kukho iiyantlukwano eziphambili phakathi kwezi zimbini ezibeka bucala ngokwemigaqo yezicelo kunye nokusebenza kwazo.

Omnye wowona mahluko uphambili phakathi kwe-RCD kunye ne-RCBO bubuchule babo obuhlukeneyo.Ngelixa i-RCD yenzelwe ukubonelela ngokhuseleko kwimisinga yokuvuza komhlaba kunye nomngcipheko wokothuka kombane, i-RCBO ithatha inyathelo eliya phambili ngokunika ukhuseleko kwi-overcurrents.Oku kwenza i-RCBOs ibe sisisombululo esisebenzisekayo kunye nesibanzi sokhuseleko lombane, ngakumbi kwiindawo apho umngcipheko wokugqithiswa kwe-overcurrents ukhona.

Omnye umahluko obalulekileyo phakathi kwee-RCBOs nee-RCD kukufako kwazo kunye neemfuno zocingo.Ii-RCBOs ziyilelwe ukuba zifakwe ngendlela evumela iisekethe zomntu ngamnye ukuba zikhuselwe zizixhobo zazo ezizinikeleyo.Oku kuthetha ukuba xa kukho impazamo okanye ukulayisha ngaphezulu, kuphela isiphaluka esichaphazelekayo siya kukhubeka, sivumele ezinye iisekethe ukuba zihlale zisebenza.Ngakolunye uhlangothi, ii-RCDs zifakwe ngokuqhelekileyo kwibhodi yokusabalalisa kwaye zibonelela ngokhuseleko kwiisekethe ezininzi, okwenza ukuba zifaneleke ngakumbi ukhuseleko olubanzi kodwa zilungelelaniswe ngaphantsi kweemfuno zesekethe nganye.

Ngokwezinto ezisebenzayo, ii-RCBOs ziluncedo ngakumbi kwiindawo apho ukuqhubeka kobonelelo lwamandla kubaluleke kakhulu, njengakwizicwangciso zorhwebo okanye kushishino.Ngokubonelela ngokhuseleko olujoliswe kuyo kwiisekethe zomntu ngamnye, ii-RCBO zinceda ukunciphisa ixesha lokuphumla kunye nokuphazamiseka okubangelwa yimpazamo yombane, ekugqibeleni igalelo kwinkqubo yombane ethembekileyo nesebenzayo.

Ukuqukumbela, ii-RCBOs zibonelela ngenqanaba eliphezulu lokhuseleko xa kuthelekiswa nee-RCDs ngokudibanisa ukuvuza komhlaba kunye nokukhuselwa ngokugqithisileyo kwisixhobo esinye.Ukukwazi kwabo ukubonelela ngokhuseleko olujoliswe kuyo kwiisekethe zomntu ngamnye kubenza babe yimpahla ebalulekileyo kwiinkqubo zokukhusela umbane, ngokukodwa kwiindawo apho umngcipheko wokugqithiswa kwe-overcurrents uxhaphake.Ukuqonda imisebenzi eyodwa kunye nomahluko phakathi kwe-RCBOs kunye nee-RCDs kubalulekile ekuqinisekiseni ukuphunyezwa okusebenzayo kwamanyathelo okhuseleko lombane kwiindawo ezahlukeneyo.
