Ikhebula eliyisicaba, njengoba igama layo lisho ukuthi isakhiwo sekhebula siyisicaba, ngenxa yesakhiwo sayo esilula, ngakho-ke inesisindo esincane, amandla aphezulu, usayizi omncane, kulula ukuyifaka, eshibhile njalonjalo.Isetshenziswa kabanzi ohlelweni lokulawula isivinini semoto ye-DC enamandla amakhulu.Ku-low voltage switchgear kanye nesistimu yokushayela imoto, isetshenziswa kakhulu ukudlulisa isignali nokulawula imishini.
①Isisindo esincane
Ngenxa yokuthi isakhiwo sekhebula eliyisicaba silula, awudingi umugqa wethusi owugqinsi, futhi awudingi ingxenye enkulu ye-conductor, ngakho-ke ilula ngesisindo.Ikakhulukazi izintambo eziyisicaba ezinezakhiwo eziyinkimbinkimbi (njengamabhande ethusi nensimbi), isisindo singancishiswa cishe ngesigamu.Ukushintsha ikhebula elivamile ngekhebula eliyisicaba nendawo yesigaba esifanayo kungasindisa imali eningi futhi kunciphise izindleko zezinto.
Ngaphezu kwalokho, ngenxa yokuthi ikhebula eliyisicaba lilula ngesakhiwo, imodeli yensiza inganciphisa izindleko zokubeka.
Ngaphansi kwezimo ezijwayelekile, ekubalweni kwezindleko zokubeka kufanele kufake ukugcinwa, ukususwa, izindleko zokuphatha, uma kuphela ubude bangempela bekhebula kuzoba ngaphezu kuka-30% wezindleko.
②Amandla aphezulu
Ikhebula eliyisicaba linezici ezinhle zomshini nokumelana nokushisa, i-radius yayo yokugoba ingaba yindilinga noma iwunxande.Ububanzi bekhebula eliyisicaba lingaba ngu-50 kuya ku-100 mm, lingamelana ne-radius egobile enkulu, futhi isenamandla aphezulu ngemva kokugoba.Ngaphezu kwalokho, ngenxa yesakhiwo sayo esihlangene, ikhebula eliyisicaba lingasetshenziswa esikhundleni sekhebula elivamile kwezinye izimo.Isibonelo ukuxhumana phakathi kwesignali nedivayisi yokulawula.Ngenxa yokuthi ikhebula eliyisicaba linesici sokusebenza okuhle esingenhla, ngakho-ke intengo yayo ishibhile kunekhebula evamile.
③Incane ngosayizi
Ngenxa yokuthi isakhiwo sekhebula eliyisicaba silula, umthamo wezinto zayo ezincane, ngakho-ke uma uthenga ungasindisa isikhala.Akukho ubakaki okhethekile odingekayo ukuze kufakwe.Ngesikhathi esifanayo, ngenxa yesakhiwo sayo esilula, ubude bezinto kanye nezintambo ezisetshenziselwa izintambo zingancishiswa ukuze kuncishiswe izindleko futhi kuphinde kugcinwe indawo yokufaka.
④Kulula ukufaka, ukunakekela nokuphatha
Ikhebula eliyisicaba liwuhlobo lwekhebuli eyongayo.Ngenxa yesakhiwo sayo esilula, sinezinzuzo zesayizi encane, isisindo esincane, ukufakwa kalula, ukugcinwa nokuphathwa.Phakathi naleso sikhathi, impilo yesevisi ye-copper core ifushaniswa ngoba i-copper core akulula ukuba i-oxidized.
I-1, Ikhebula eliyisicaba liwuhlobo lwekhebula eliyisicaba elinokuvumelana nezimo ezinhle, ngakho kulula ukusebenza ekwakhiweni.
2, Ngenxa yokuthi ikhebula eliyisicaba linesisindo esincane, asikho isidingo sokwenza ukuhlelwa kwe-typesetting nokubala ngaphambi kokubeka.Lena inzuzo elula kochwepheshe nabakhi.
3, Ngenxa yokuthi ikhebula eliyisicaba liqinile kakhulu futhi kulula ukulifaka nokuyigcina, isikhathi sokunakekela singafinyezwa futhi izindleko zingancishiswa.
I-4, Ngenxa yokuthi inani lezintambo kukhebula eliyisicaba lincane kakhulu, inani lamaphuzu wephutha lincane, ngaleyo ndlela linciphisa kakhulu ukwenzeka kwamaphutha okusebenza futhi lithuthukise kakhulu ukusebenza kahle komsebenzi.
I-5, Ikhebula eliyisicaba liphinde libe uhlobo lwekhebula lokudlulisa isignali, elingadlulisa amasignali ngokudluliswa okungenantambo.
⑤Intengo ephansi, ukusebenza kahle kwentengo
Uma kuqhathaniswa nekhebula lendabuko, ikhebula eliyisicaba linezinzuzo ezisobala ngentengo, njengokuthi: 1, intengo ishibhile kakhulu kunekhebula lendabuko, 2, ukufakwa kwayo kungaqedwa ngaphandle kwanoma yimaphi amathuluzi nobuchwepheshe bokusebenza, 3, ingasebenzisa ikhebula elingamelana nowoyela. njengemishini yekhebula lamandla.
Ikhebula eliyisicaba ekusetshenzisweni okungokoqobo lisetshenziswa ohlelweni lokusatshalaliswa kwe-voltage ephansi, futhi ohlelweni lokusabalalisa lwamandla aphansi luwuhlelo olusetshenziswa kakhulu lwezigaba ezintathu ezinezintambo ezine.Isistimu yokusabalalisa i-low-voltage isebenzisa uhlelo lwezintambo ezine ezinezigaba ezintathu, lapho ukucushwa okudingekayo kwemishini kukhona: ibhokisi lokusabalalisa, iKhabhinethi yokulawula ukukhanyisa, ibhokisi lokusabalalisa amandla nokunye.
