Isigaba sesi-3 – Iqondwa kanjani incazelo “yesisetshenziswa esisetshenziswa esisezingeni lesi-III”

Into esetshenziswayo yesigaba III: into esetshenziswayo lapho ukuvikeleka kokushaqiswa kukagesi kuncike ekunikezeni amandla kagesi aphansi kakhulu futhi lapho ama-voltage aphezulu kunalawo okuphepha kwamandla kagesi aphansi kakhulu angakhiqizi.
QAPHELA Ukufakwa okuyisisekelo kungase kudingeke ngaphezu kokuhlinzekwa kwa-SELV. Bheka ku-8.1.4.
Ukuze uqonde lokhu, udinga ukuqonda kuqala ukuthi yini ukuphepha kwamandla kagesi aphansi kakhulu(SELV). Sicela ubheke incazelo kanye nencazelo ye-SELV. Lolu hlobo lomkhiqizo ngokuvamile lunikwa amandla i-adaptha, i-USB, noma ugesi we-low-voltage emotweni. Uma lolu hlobo lomkhiqizo luthengiswa, ngeke lufakwe idivayisi eguqula amandla angu-100-240V AC abe amandla kagesi adingekayo aphansi, ngoba uma ifakwe idivayisi enjalo yokuguqula, njenge-adaptha, i-adaptha kanye Ifomu lomshini liphelele, futhi izinga lokuvikela lonke linqunywa i-adaptha. I-adaptha imvamisa iwukwakhiwa kwekilasi II, ngakho-ke i-adaptha nento esetshenziswayo kuchazwa njengomshini wesigaba II. Ngenxa yokuthi amandla kagesi alolu hlobo aphansi uma kuqhathaniswa, ngezinye izikhathi aholela ekungakwazini ukuqedela imisebenzi ethile kagesi, ngakho-ke kuyadingeka ukusebenzisa i-boost circuit ukwandisa amandla kagesi ukuze kuzuzwe imisebenzi ethile ekhethekile yomshini. Isibonelo, umsebenzi wejeneretha ye-ion engalungile udinga ukusebenza kwe-boost. Lolu hlobo lwesisetshenziswa esinejeneretha ye-ion eyinegethivu efanayo noma i-boost operation (ivelu ye-voltage ephakeme kune-SELV) alukwazi ukunqunywa njengesisetshenziswa sikagesi seSigaba III.

Igama elithi “ukuphepha” lifakwe emagameni amane “ukuphepha okunamandla kagesi aphansi”, kodwa lokhu akusho ukuthi i-SELV iphephile, futhi ayiphephile ngempela ukuyithinta ngokuqondile. Ukuphepha kuphela kwamasekhethi anamandla kagesi aphansi ahlangabezana nezidingo zezinga elingu-8.1.4 okungathintwa ngokuqondile. Sizokuhlaziya futhi sikuchaze lokhu lapho sihlaziya isigatshana 8.1.4.

Ifeni eboniswe emfanekisweni ongezansi ingachazwa njengento esebenza esigabeni III. Kodwa-ke, lo mlandeli unezindlebe ezimbili, okwenza ukuthi angahambisani nesigatshana 22.44. Imininingwane sizoyichaza kamuva.
