Yintoni i-RCD

Inkcazo

Usenokuliva igama elithi rcd rhoqo xa uthetha ngokhuseleko lombane. I-RCD imele isixhobo samandla asele. Esi sixhobo sisebenza njengesitshixo sokhuseleko lombane esikhuselekileyo esikukhusela kwiimpazamo eziyingozi. Ngokwemigangatho yokhuseleko lombane yamazwe ngamazwe, isixhobo samandla asele siphazamisa isekethe yombane xa amandla adlula kumgca kwaye ii-conductors ezingathathi cala zingalingani. Lo mahluko uthetha ukuba amanye amandla avuza, mhlawumbi ngomntu okanye emhlabeni. I-rcd ingena ukuze inciphise ukwenzakala ngenxa yokutshona kombane.

Nantsi inkcazo ecacileyo:

Ungafumana ii-rcd emakhayeni, kwiiofisi, nakwiindawo ezininzi zikawonke-wonke. Zisebenza ngokuthula ngasemva, zisoloko zilungele ukwenza into ukuba kukho into engahambi kakuhle.

Umsebenzi oPhambili

Umsebenzi ophambili we-rcd kukubona iimpazamo zombane kunye nokuqhawula umbane kwii-milliseconds. Uxhomekeke kwesi senzo sikhawulezayo ukuthintela ukutshayiswa kombane kunye nomlilo. I-rcd ihlala ijonga ukuhamba kombane kwiisekethe zakho. Ijonga ukuba umbane ophumayo ngentambo ephilayo uyahambelana na nombane obuyayo ngentambo engathathi cala. Ukuba i-rcd iva umahluko omncinci, iyazi ukuba kukho into engalunganga.

I-rcd kufuneka ibone iintlobo ezahlukeneyo zamandla ombane, kuquka i-AC kunye ne-DC.

Isebenzisa iikhoyili kunye nesiseko semagnethi ukuze iqonde ukungalingani.
