Moteri ifite ingufu nyinshi
Muri rusange abantu bemera ko moteri ifite voltage y'amashanyarazi ya 3KV ~ 10KV yitwamoteri ifite ingufu nyinshiMoteri za 6300V na 10000V zikunze gukoreshwa. Ingufu za moteri zijyanye n'umusaruro w'amashanyarazi n'amashanyarazi, bityo imbaraga za moteri ifite ingufu nke ziyongera ku rugero runaka (nk'300KW/380V), ingufu zizaba nini cyane, igihombo cy'umurongo kizaba kare hamwe n'ubwiyongere bw'amashanyarazi (I^2*r), agace k'insinga gasabwa kuba kanini cyane, bityo ubushobozi bwemewe bwo gutwara insinga ni buke, kandi igiciro ni kinini cyane. Muri iki gihe, ni ngombwa kongera ingufu zikoreshwa kugira ngo haboneke ingufu nyinshi.
Moteri ifite voltage nkeya
Moteri ifite voltage nke yerekeza kuri moteri ya AC iri munsi ya 1000V, muri rusange yerekeza kuri moteri ya AC 380V, 440V cyangwa 660V n'izindi nzego zamoteri zidahuzaMu by’ukuri zikoreshwa gake. Moteri ifite ingufu nke igabanyijemo moteri idafite ingufu za AC na moteri ya DC moteri ebyiri.
Ibyiza n'ibibi bya moteri zifite amashanyarazi menshi ugereranije na moteri zifite amashanyarazi make
(1) Ibyiza
(1) ishobora gukorwa ku ngufu nini, kugeza ku bihumbi cyangwa ndetse n'ibihumbi bya kilowati. Ibi biterwa nuko, mu ngufu zimwe zisohoka, moteri ifite ingufu nyinshi ishobora kuba nto cyane ugereranije na moteri ifite ingufu nke (mu buryo bunyuranye n'amashanyarazi), urugero, 500kW, moteri ifite ingufu 4, ingufu zingana na 380V kuri 900A cyangwa hafi yayo, mu gihe ingufu zingana na 10kV ari 30A gusa. Bityo, moteri ifite ingufu nyinshi ishobora kuba ifite umurambararo muto w'insinga. Kubera iyo mpamvu, igihombo cya stator umuringa cya moteri ifite ingufu nyinshi nacyo kizaba gito ugereranyije n'icya moteri ifite ingufu nke. Kuri moteri nini, gukoresha amashanyarazi afite ingufu nke, ariko kubera ko hakenewe insinga nini kandi hakenewe agace kanini k'umuyoboro wa stator, kugira ngo umurambararo w'ibanze wa stator ukore akazi kenshi, ingano yose ya moteri nayo izaba nini cyane.
② Ku moteri nini zifite ubushobozi bwo gutwara umuriro, moteri zifite ingufu nyinshi zikoreshwa mu gutanga amashanyarazi no gukwirakwiza umuriro ni nkeya kurusha ishoramari rusange muri moteri zifite ingufu nke, kandi igihombo cy'umurongo ni gito, bishobora kuzigama ingano runaka y'ikoreshwa ry'ingufu. By'umwihariko, moteri zifite ingufu nyinshi za 10kV, ushobora gukoresha amashanyarazi y'umuyoboro w'amashanyarazi (amashanyarazi menshi yo mu Bushinwa ahabwa abakoresha muri rusange ni 10kV), bityo ishoramari mu bikoresho by'ingufu (cyane cyane transformateur) rizaba rito, ikoreshwa ryoroheje, igipimo cyo gutsindwa kizaba gito.
(2) Ingaruka mbi
① Igiciro cyo gupfunyika kiri hejuru cyane (cyane cyane giterwa n'ubushyuhe bw'amashanyarazi), kandi igiciro cy'ibikoresho bifitanye isano na byo kizaba kinini.
(ii) Uburyo bwo gutunganya insulation burushaho kugorana, kandi ikiguzi cy'abakozi kiri hejuru.
③ Ibisabwa mu ikoreshwa ry'ibidukikije birakomeye cyane kurusha ibya moteri zifite voltage nke.
Kugereranya itandukaniro riri hagati ya moteri ifite voltage nke na moteri ifite voltage nyinshi
Itandukaniro rikomeye mu miterere
Ubwa mbere, ibikoresho byo gukingira imiyoboro bigira icyo bihindura, moteri zifite voltage nkeya, insinga zivanze cyane cyane na enamel cyangwa izindi mpushya zoroshye zo gukingira imiyoboro, nk'impapuro zivanze, inshushyamiyoboro ifite voltage nyinshi ikoreshwa mu miterere y'ibice byinshi, nka mica tape ifu, imiterere yayo iragoye cyane, kandi ifite ubushobozi bwo kurwanya umuvuduko mwinshi.
Icya kabiri, itandukaniro mu miterere y'ubukonje, moteri zifite voltage nkeya ahanini zikoresha amafeni ya coaxial ahuha mu buryo butaziguye kugira ngo ashire ubushyuhe, moteri zifite voltage nyinshi hamwe na radiator yigenga, akenshi ubwoko bubiri bw'amafeni, itsinda ry'amafeni azenguruka imbere, itsinda ry'amafeni azenguruka hanze, amafeni abiri azenguruka icyarimwe, ubushyuhe kuri radiator buzasohoka hanze y'ubushyuhe bwa moteri.
Icya gatatu, imiterere y’ubwikorezi iratandukanye, moteri zifite voltage nkeya akenshi ziba zifite imiterere y’ubwikorezi mbere na nyuma, mu gihe moteri zifite voltage nyinshi, kubera umutwaro uremereye, akenshi haba hari imiterere ibiri y’ubwikorezi ku mpera y’umurongo, kandi umubare w’ubwikorezi ku mpera idashingiye ku murongo ugenwa hakurikijwe imiterere y’umutwaro, cyane cyane moteri nini zizakoresha ubwikorezi bugenda buhindagurika.
Kugereranya imikorere ya moteri n'ikiguzi cyayo
1. Uko urwego rw'amashanyarazi ruri hejuru, niko ubushobozi bwa moteri buba bwinshi.
2, uko urwego rw'amashanyarazi rurushaho kuba rwinshi, niko ikiguzi cyo gushyiraho kiyongera; nubwo amashanyarazi yiyongera, umuyoboro w'amashanyarazi urushaho kuba muto, insinga n'insinga bishobora gutoranywa bikaba bike, ariko ikiguzi cy'ibikoresho bifite ingufu nyinshi, transformateur, switchgear n'ibindi bikoresho kiracyariyongera mu ishoramari rya mbere mu manini, bityo ubucuruzi buto mu bwubatsi bushya bwiteguye gukoresha ibikoresho bifite ingufu nke.
3, uko urwego rw'amashanyarazi ruri hejuru, niko ikiguzi cyose cy'imikorere kigabanuka; umuriro muto wo kugabanya igihombo cy'amashanyarazi, mu gihe kirekire birakwiye, ingaruka zo kuzigama ingufu zitangaje, bityo ibigo byinshi binini mu guhindura ikoranabuhanga moteri zifite voltage nkeya zahinduwe moteri zifite voltage nyinshi.
4, uko urwego rw'amashanyarazi ruri hejuru, niko umwanya munini ukoreshwa; kuko hari utubati ducunga umuriro mwinshi n'abandi bantu batwinjiramo.
5, uko urwego rw'amashanyarazi ruri hejuru, moteri yoroshye kuyitangiza, imbaraga zo gutangira ziyongera, gutangira no kugenzura biroroshye cyane.
6, uko urwego rw'amashanyarazi ruri hejuru, niko imicungire y'ibikorwa byo kubungabunga irushaho kuba ingorabahizi; bityo ubucuruzi buto bwiteguye gukoresha ingufu nke, ibigo binini byiteguye gukoresha moteri zifite ingufu nyinshi.
