Impinduka nyamukuru ya sisitemu yo gukwirakwiza amashanyarazi ni impinduka ikosora ifite voltage ya 0.4 / 0.66 / 0,75 kV, kandi umutwaro nyamukuru ni moteri nkuru ya DC.Kuberako imbaraga zo gukwirakwiza no gukwirakwiza ibikoresho byumukoresha wa extruder ikosora muri rusange ikoresha ubwoko bubiri bwa tekinoroji itandatu ya pulse ikosora, itanga urugero runaka rwumuvuduko wa pulse (6N + 1) mubyiciro bitandukanye kuruhande rwa voltage nkeya, kandi cyane cyane (6N +1) kuruhande rwumuvuduko mwinshi.12N + 1) Erekana uburyo cumi na bubiri bumwe-bwo gukosora.
Kwangirika kwingufu zamashanyarazi kuri gride yamashanyarazi biterwa nibibi byumuvuduko wamashanyarazi ukora kumashini nibikoresho mumashanyarazi, ni ukuvuga ko imbaraga zumurimo zikora zirenze urwego imashini nibikoresho bishobora kwihanganira.Ishyaka ritanga amashanyarazi rishinzwe imbaraga za pulse ikora yumurongo wogutanga amashanyarazi, naho umuguzi w'amashanyarazi ashinzwe kumenyekanisha imiyoboro ya software ya sisitemu.
Ukurikije ubunararibonye bwubuhanga bwuruganda rwacu gakondo ruzunguruka kugirango ruhangane nubwumvikane, mubikorwa, muri sisitemu yo gukwirakwiza amashanyarazi make y’umukoresha, ibice 5 bya garmonique bigera kuri 20% ~ 25%, umuyoboro wa 7 uhuza ugera kuri 8%, n'umuyoboro uhuza winjizwa mumashanyarazi menshi Ibirimo bihuza muri sisitemu yingufu byiyongera byihuse, ibyo bigatuma imiyoboro igoreka ya voltage itanga, byongera igihombo cyinsinga nibikoresho byamashanyarazi, bizana gukoresha ingufu zindi, bigira ingaruka kumikorere isanzwe yizindi ibikoresho by'amashanyarazi muri gride y'amashanyarazi, kandi bigabanya ubwiza bw'amashanyarazi., bigira ingaruka kumutekano wamashanyarazi kandi bizana ingaruka zumutekano kumikorere yibikoresho.
Kugirango hamenyekane imikorere isanzwe yibikoresho, gutanga amashanyarazi yizewe no kuzigama ingufu za sisitemu yo gutanga amashanyarazi, birakenewe ko hafatwa ingamba za tekiniki kugirango bahagarike imiyoboro ihuza ibikoresho no gutekereza ku ndishyi z’ingufu zifatika.Nkurikije ibipimo ngenderwaho by’ibicuruzwa bikoresha ingufu za voltage mu gihugu cyanjye hamwe n’ibyavuye mu bushakashatsi bwa siyansi y’ubushakashatsi bwakozwe na pulse mu bihugu bitandukanye ku isi, haremejwe ibisobanuro bya tekiniki yo muyungurura ya voltage yo hasi ndetse n’indishyi zingirakamaro, kandi ibizunguruka bigenzura shiraho kubintu biranga pulse iterwa na rectifier kugirango igogwe kandi ikuremo imiyoboro ihuza.Mubyongeyeho, ifite imirimo yo kwishyura indinganizo yibanze yumutwaro no kuzigama ingufu za electroniki.
Ibikoresho birwanya guhuza byakozwe na Zhejiang Hongyan Electric Co., Ltd. bifite ibiranga impinduka zikomeye hamwe numutwaro.Nubwo kuzamura neza ingufu z'amashanyarazi, ibintu bitanga ingufu hamwe no kuzigama ingufu z'umuriro w'amashanyarazi, birashobora kandi kunoza ubwizerwe bw'imikorere rusange ya sisitemu y'amashanyarazi no gukoresha neza ibikoresho, kandi bikagabanya amafaranga yo gukora no kugabanya amafaranga yo gufata neza ibikoresho, kongera ibikoresho ubuzima, no kuzana inyungu zigaragara mubukungu kubakoresha.
Urusyo ruzunguruka DC rusanzwe rukoresha moteri ya DC, kandi ibintu byingufu mugihe cyo kuzunguruka ni bike cyane, muri rusange hafi 0.7.Kimwe mu bintu byingenzi biranga ni igihe gito cyo gukora, umuvuduko wihuse, umutwaro w'ingaruka, hamwe n'imihindagurikire minini itemewe.Amashanyarazi ashobora kandi gutera ihindagurika rikomeye mumashanyarazi ya gride, bigatuma amatara na ecran ya TV bihindagurika, bigatera umunaniro ukabije no kurakara.Byongeye kandi, bizagira ingaruka no kumikorere myiza yibikoresho bya thyristor, ibikoresho cyangwa ibikoresho byo gukora, ndetse bitera impanuka z'umutekano.Indishyi rusange ya banki ntishobora gukurikirana impinduka zumutwaro mugihe nyacyo kugirango ikomeze indishyi zifatika.Ibikoresho bya mashini bitumanaho bigira ingaruka kuberako guhinduranya kenshi, bigira ingaruka zikomeye kumashanyarazi.
Uruganda rwa DC rukoresha amashanyarazi ya tekinoroji yo gukosora thyristor.Ukurikije umubare wogukosora impiswi, irashobora kugabanywamo 6-gukosora, 12-pulse kugeza 24-pulse.Usibye imbaraga nkeya, guhuza-murwego rwohejuru bizabyara mugihe cyakazi.Mubisanzwe, uruganda ruzunguruka DC murugo Ikoreshwa rya tekinoroji ya 6-pulse ikoreshwa, bityo rero murwego rwohejuru rwohejuru rwakozwe numurongo umwe wumuvuduko muke uhinduranya uruhande rwa transformateur rukosora ni 11 na 13 muruhande rwa voltage nkeya ya transformateur hamwe na 2 guhinduranya bikora hamwe yn uburyo bukomatanyije, icya 5 nicya 7 bihuza-byateganijwe birashobora guhagarikwa kuruhande rwumuvuduko mwinshi, bityo ibice 11 na 13 byo murwego rwohejuru bihuza byerekanwa cyane cyane kuruhande rwumuvuduko mwinshi.Ingaruka nyamukuru zumuvuduko ukabije wumuvuduko wamashanyarazi kuri gride yamashanyarazi harimo gushyushya no kunyeganyeza ibikoresho byamashanyarazi, gutakaza igihombo, igihe gito cya serivisi, ingaruka zitumanaho, ikosa rya imikorere ya thyristor, ikosa ryibikorwa bya bimwe mubikoresho birinda ibyuma, gusaza no kwangirika kwamashanyarazi , n'ibindi.
Ibisubizo byo guhitamo muri:
Igisubizo 1 Ubuyobozi bukomatanyije (bukoreshwa kubushobozi buke buke, ibumoso niburyo)
1. Emera ishami rishinzwe kugenzura (3, 5, 7 muyunguruzi) + ishami rishinzwe kugenzura ingufu.Nyuma yo gushungura ibikoresho byungururwa bimaze gukoreshwa, kugenzura guhuza no kwishyurwa kwingufu za sisitemu yo gutanga amashanyarazi byujuje ibisabwa.
2. Koresha umuzenguruko wa bypass uhagarika indishyi zidahwitse zubwumvikane, hanyuma nyuma yo guhuza igikoresho cyindishyi zungurura, kora ibintu byingufu byujuje ibisabwa
Ihitamo rya 2 Ubuvuzi bwibanze (burakoreshwa kuri 12-pulse rectifier transformateur ya voltage nkeya kuruhande hamwe na moteri nkuru yingufu hamwe na mashini ihinduranya yashizwe ukwayo)
1. Emera bypass anti-garmonic bypass (5, 7, 11, 11) nyuma yo gukoreshwa.
2. Ukoresheje akayunguruzo gakora (gushungura dinamike ihuza) hamwe no kuyungurura bypass (5, 7, 11 byateganijwe gushungura), guhuza nyuma yo gufungura ntabwo bigera kurwego rusanzwe.
