Waya dzinowanzonzi "tambo".Ndivo vatakuri vekufambisa simba remagetsi uye ndiwo mamiriro ekutanga ekugadzira zvishwe pakati pemidziyo yemagetsi.Izvo zvakakosha zvekufambisa kwewaya zvinowanzogadzirwa nemhangura kana aluminium zvinhu.
Mutengo wewaya dzinoshandiswa mumashandisirwo akasiyana zvakasiyana.Somuenzaniso, zvinhu zvinokosha zvesimbi hazviwanzoshandiswa sewaya.Waya dzinogonawo kukamurwa zvinoenderana nemamiriro ekushandisa.Semuenzaniso, kana ikozvino yakakura, tichashandisa high-current waya.
Naizvozvo, waya dzinochinjika zvakanyanya mumashandisirwo chaiwo.Saka, patinosarudza kutenga, ndeupi rudzi rwehukama husingadzivisiki huripo pakati pehupamhi hwetambo uye ikozvino.
Hukama pakati pewaya dhayamita uye ikozvino
Muhupenyu hwedu hwezuva nezuva, waya dzakajairika dzakatetepa kwazvo.Chikonzero ndechekuti ikozvino yavanotakura kana vachishanda idiki kwazvo.Muchigadziro chemagetsi, kubuda kwemazuva e-low-voltage side ye-transformer inowanzova nhamba yezvino inoshandiswa nemushandisi, kubva kumazana mashoma amperes kusvika kuzviuru zveamperes.
Zvadaro tinosarudza hombe waya dhayamita kusangana zvakakwana overcurrent kukwanisa.Zviripachena, dhayamita yewaya inoenderana neyazvino, ndiko kuti, iyo yakakura ikozvino, iyo yakakura nzvimbo yemuchinjikwa-chikamu chewaya.
Hukama huri pakati pemuchinjiko-chikamu nharaunda yewaya uye yazvino iri pachena.Ikozvino kutakura kugona kwewaya kunoenderanawo nekupisa.Iyo yakakwirira tembiricha, iyo yakakura resistative yewaya, iyo yakakura kuramba, uye yakakura mashandisiro emagetsi.
Nokudaro, maererano nesarudzo, tinoedza kusarudza tambo yakakura zvishoma kudarika yakarongwa ikozvino, iyo inogona kunyatsodzivisa mamiriro ari pamusoro apa.
Iyo mhiri-chikamu nzvimbo yewaya inowanzoverengerwa zvinoenderana neinotevera formula:
Waya yemhangura: S = (IL) / (54.4 △U)
Aluminium waya: S = (IL) / (34 △U)
Ikoko: Ini - Yakawanda ikozvino inopfuura nepawaya (A)
L - Kureba kwewaya (M)
△U - Inobvumidzwa kudonha kwemagetsi (V)
S - Muchinjikwa-chikamu nzvimbo yewaya (MM2)
Iyo yazvino iyo inowanzo pfuura nemuchinjika-chikamu nharaunda yewaya inogona kusarudzwa zvichienderana nehuwandu hwehuwandu hwainoda kuita, iyo inogona kugaro tara maererano neinotevera jingle:
Rhyme yewaya muchinjiko-chikamu nzvimbo uye zvazvino
Gumi ishanu, zana imbiri, mbiri shanu shanu ina matatu miganhu, makumi manomwe nepfumbamwe neshanu kaviri nehafu, copper wire upgrade kuverenga
Pawaya dzealuminium dziri pasi pe10 mm2, wedzera masikweya millimita ne5 kuti uzive ampere iripo yemutoro wakachengeteka.Kune waya dziri pamusoro pe 100 square millimeters, wedzera nzvimbo yemuchinjikwa ne 2;kune waya dziri pasi pe 25 square millimeters, wedzera ne 4;kune waya dziri pamusoro pe35 square millimeters, wedzera ne3;pawaya dziri pakati pe70 ne95 square millimeters, wedzera ne 2.5.Kune waya dzemhangura, enda kumusoro, semuenzaniso, 2.5 square millimeters yemhangura waya inoverengwa se 4 square millimeters.(Cherechedza: Zviri pamusoro zvinogona kungoshandiswa sefungidziro uye hazvina kunyatsojeka.)
Mukuwedzera, kana iri mukati, yeuka kuti kune waya dzemhangura dzine core cross-sectional area isingasviki 6 mm2, yakachengeteka kana ikozvino pamativi millimeter isingapfuuri 10A.
Mukati memamita gumi, kuwanda kwewaya ndeye 6A/mm2, 10-50 metres, 3A/mm2, 50-200 metres, 2A/mm2, uye isingasviki 1A/mm2 yewaya dzinopfuura 500 metres.Iyo impedance yewaya inoenderana nehurefu hwayo uye inversely proportional kune dhayamita yewaya.Ndokumbira utarise zvakanyanya kune waya zvinhu uye waya dhayamita paunenge uchishandisa magetsi.Kudzivirira kupisa kwakanyanya kubva mukupisa waya uye kukonzera njodzi.
