Ukukhetha kwesokudlai-transformer yamanje ye-voltage ephansikusho ukugxila ekunembeni, ekushiseni, ekusebenzeni kokushisa, kanye namandla omshini. Imininingwane ngayinye ithinta ukusebenza, ukuphepha, kanye nezindleko. Isibonelo, amakilasi okunemba aphezulu anciphisa amaphutha kodwa angandisa izindleko, kuyilapho izinketho zokufaka eziqinile kanye nokufakwa zivikela imishini ezindaweni ezidinga kakhulu. Uchungechunge lwe-LMZ lwe-Maliotech lubonisa lezi zimfanelo, lunikeza ukufakwa okunembile okuphezulu kanye nokuguquguquka. Ezimweni zangempela, ukufanisa imininingwane ye-transformer nohlelo lwakho lokusebenza kuqinisekisa ukusebenza okuthembekile kanye nenani lesikhathi eside.
Izisekelo Zokuguqula Amandla Aphansi Kwamanje
Ukukhetha i-voltage ephansi efanelei-transformer yamanjeKuqala ngokuqonda izici ezimbalwa ezibalulekile. Lokhu kufaka phakathi izilinganiso zamanje eziyinhloko nezesibili, isilinganiso sokuguqulwa, kanye nesigaba sokunemba. Ngayinye yalezi zici idlala indima enkulu ekutheni i-transformer izosebenza kahle kangakanani kuhlelo lwakho lokusebenza.
Izilinganiso Zamanje Eziyinhloko Nezesibili
Isilinganiso samandla ayinhloko sikutshela ukuthi ugesi omkhulu kangakanani i-transformer engakwazi ukuwuphatha ohlangothini lokufaka. Isilinganiso samandla angesibili yigesi yokukhipha enikezwa yi-transformer kumadivayisi okulinganisa noma okuvikela. Ama-transformer amaningi angenamandla aphansi anegesi yesibili ejwayelekile engu-1 ampere noma ama-5 ampere. Lokhu kumiswa kusiza ukuqinisekisa ukuhambisana namamitha kanye nama-relay.
- Izilinganiso zamanje zesibili ezijwayelekile:
- 1 ampere (A)
- Ama-ampere ama-5 (A)
Ukukhetha izilinganiso zamanje eziyinhloko nezesibili ezifanele kubalulekile kokubili ekusebenzeni nasekuphepheni. Uma izilinganiso zingahambisani nohlelo lwakho, kungavela izinkinga eziningana:
- Ukulinganisa okungalungile kungathinta ukufakwa konke.
- Ukulayisha ngokweqile kungabangela ukugcwala kwe-core, okwandisa amaphutha okulinganisa futhi kufushanise impilo ye-transformer.
- Ukwehluleka kokufakwa kokushisa kungaholela ekushiseni ngokweqile, okungabangela umonakalo noma ngisho nokuqhuma.
- Isekethe yesibili evulekile ingadala ama-voltage aphezulu kakhulu, angabangela ukushaqeka kukagesi, ama-arcs, noma imililo.
Icebiso: Njalo fanisa izilinganiso zamanje ze-transformer nezidingo zesistimu yakho ukuze ugweme lezi zingozi.
