Chipangizo chowongolera voteji cha thiransifoma chimagawidwa kukhala chosinthira chamagetsi cha "off-excitation" ndi chosinthira "pa-load" chosinthira.
Onsewa amatanthawuza njira yoyendetsera magetsi ya chosinthira tap tap, ndiye pali kusiyana kotani pakati pa ziwirizi?
① The "off-excitation" tap chosinthira ndikusintha kampopi wam'mbali wokwera kwambiri wa thiransifoma kuti asinthe matembenuzidwe a mapindikidwe a kayendetsedwe ka magetsi pomwe mbali zonse zoyambirira ndi zachiwiri za thiransifoma zachotsedwa pamagetsi.
② "On-load" chosinthira chapampopi: Pogwiritsa ntchito chosinthira chapampopi, chosinthira chosinthira thiransifoma chimasinthidwa kuti chisinthe matembenuzidwe amphamvu kwambiri pakuwongolera magetsi osadula katundu wapano.
Kusiyanitsa pakati pa awiriwa ndikuti chosinthira chotsitsa chotsitsa sichimatha kusintha magiya ndi katundu, chifukwa mtundu uwu wakusintha kwapampopi umakhala ndi njira yanthawi yochepa yolumikizira panthawi yosinthira zida. Kuchotsa chojambulira chaposachedwa kumayambitsa kukangana pakati pa omwe akulumikizana ndikuwononga chosinthira chapampopi. Chosinthira chapampopi chonyamula chimakhala ndi kusintha kopitilira muyeso panthawi yosinthira zida, kotero palibe njira yodutsira kwakanthawi kochepa. Mukasintha kuchokera ku gear kupita ku ina, palibe njira yochepetsera pamene katundu wamakono achotsedwa. Nthawi zambiri amagwiritsidwa ntchito pa ma transfoma omwe ali ndi zofunikira zamagetsi zomwe zimafunikira kusinthidwa pafupipafupi.
Popeza thiransifoma "on-load" tap changer imatha kuzindikira ntchito yoyendetsera magetsi pansi pa ntchito ya thiransifoma, bwanji kusankha chosinthira "chotsitsa"? Inde, chifukwa choyamba ndi mtengo. Munthawi yanthawi zonse, mtengo wa chosinthira chotsitsa chotsitsa ndi 2/3 pamtengo wa chosinthira chosinthira chapampopi; nthawi yomweyo, voliyumu ya thiransifoma yapampopi yotsitsa ndi yaying'ono kwambiri chifukwa ilibe gawo losinthira tap-load. Chifukwa chake, pakapanda malamulo kapena zochitika zina, chosinthira chosinthira chotsitsa chotsitsa chidzasankhidwa.
Chifukwa chiyani musankhe chosinthira chosinthira pamagetsi pamagetsi? Ntchito yake ndi yotani?
① Sinthani kuchuluka kwa kuyenerera kwamagetsi.
Kutumiza kwamphamvu muukonde wogawa mphamvu kumapanga zotayika, ndipo mtengo wotayika ndiwochepa kwambiri pafupi ndi voliyumu yomwe idavoteledwa. Kukhazikitsa malamulo amagetsi onyamula katundu, nthawi zonse kusunga magetsi a mabasi apansi pang'ono kukhala oyenera, ndikupanga zida zamagetsi kuti ziziyenda pamagetsi ovotera kumachepetsa kutayika, komwe kumakhala kotsika mtengo komanso koyenera. Kuyenerera kwamagetsi ndi chimodzi mwa zizindikiro zofunika za khalidwe lamagetsi. Kuwongolera kwamagetsi munthawi yake kumatha kuwonetsetsa kuti kuyenerera kwamagetsi kumakwaniritsa zosowa za miyoyo ya anthu komanso kupanga mafakitale ndi zaulimi.
② Sinthani mphamvu zolipirira mphamvu ndikuwonjezera kuchuluka kwa ma capacitor.
Monga chipangizo cholipirira mphamvu, mphamvu yotulutsa mphamvu ya ma capacitor amafanana ndi sikweya yamagetsi ogwiritsira ntchito. Mphamvu yogwiritsira ntchito mphamvu yamagetsi ikachepa, chipukuta misozi chimachepa, ndipo mphamvu yogwiritsira ntchito ikawonjezeka, zida zamagetsi zimakulitsidwa, zomwe zimapangitsa kuti magetsi azitha kuwonjezeka, ngakhale kupitirira muyezo, zomwe zimakhala zosavuta kuwononga kusungunula kwa zipangizo. ndi chifukwa
ngozi za zida. Pofuna kuteteza mphamvu yogwira ntchito kuti isabwezedwe kumagetsi ndi zida zolipirira mphamvu zamagetsi kuti zithe kuyimitsidwa, zomwe zimapangitsa kuti ziwonongeke komanso kutayika kwa zida zamagetsi zamagetsi, chosinthira chachikulu chosinthira magetsi chiyenera kusinthidwa munthawi yake kuti musinthe basi. voteji ku oyenerera osiyanasiyana, kotero kuti palibe chifukwa kuletsa chipukuta misozi capacitor.
Momwe mungagwiritsire ntchito lamulo la voltage pa-load?
Njira zoyendetsera magetsi pamagetsi zimaphatikizanso kuwongolera mphamvu yamagetsi amagetsi ndi kuwongolera ma voltage pamanja.
Chofunikira cha on-load voltage regulation ndikusintha voteji posintha kusintha kwa gawo lapamwamba-voltage pomwe voteji kumbali ya low-voltage imakhalabe yosasinthika. Tonse tikudziwa kuti mbali yamphamvu kwambiri nthawi zambiri imakhala yamagetsi, ndipo voteji yamagetsi nthawi zambiri imakhala yosasintha. Pamene chiwerengero cha matembenuzidwe pamapiritsi apamwamba-voltage mbali chikuwonjezeka (ndiko kuti, chiŵerengero cha kusintha chikuwonjezeka), voteji kumbali yotsika-voltage idzachepa; m'malo mwake, pamene chiwerengero cha matembenuzidwe pa mapiritsi apamwamba-voltage mbali yafupika (ndiko kuti, kusintha kwa chiŵerengero kumachepetsedwa), voteji kumbali yotsika-voltage idzawonjezeka. Ndiko kuti:
Onjezani matembenuzidwe = downshift = kuchepetsa voteji Kuchepetsa kutembenuka = upshift = kuwonjezeka kwamagetsi
Ndiye, ndi zinthu ziti zomwe thiransifoma singagwire pa-load tap chosinthira?
① Transformer ikadzaza (kupatula zochitika zapadera)
② Pamene alamu ya gasi yowunikira ya chipangizo chowongolera magetsi ikatsegulidwa
③ Pamene kukana kwamphamvu kwamafuta pa chipangizo chowongolera voteji sikuli koyenerera kapena palibe mafuta pamtundu wamafuta.
④ Pamene chiwerengero cha magetsi chikuposa chiwerengero chomwe chatchulidwa
⑤ Pamene chipangizo chowongolera magetsi sichikhala bwino
Chifukwa chiyani kuchulukitsidwa kumatsekanso chosinthira chotsitsa?
Izi ndichifukwa choti munthawi yanthawi zonse, panthawi yowongolera voteji ya thiransifoma yayikulu, pamakhala kusiyana kwamagetsi pakati pa cholumikizira chachikulu ndi cholumikizira chandamale, chomwe chimapanga magetsi ozungulira. Chifukwa chake, panthawi yowongolera voteji, chopinga chimalumikizidwa mofananira kuti chizidutse pakali pano ndikunyamula. The resistor parallel iyenera kupirira mphamvu yayikulu.
Pamene thiransifoma yamagetsi yadzaza, mphamvu yogwiritsira ntchito thiransifoma yaikulu imaposa mphamvu yomwe ilipo panopa ya chosinthira chapampopi, chomwe chikhoza kuwotcha cholumikizira chothandizira cha chosinthira chapampopi.
Choncho, pofuna kupewa arcing chosinthira wapampopi, ndi zoletsedwa kuchita pa-katundu voteji malamulo pamene thiransifoma lalikulu lodzaza. Ngati mphamvu yamagetsi ikakamizika, chipangizo chowongolera mphamvu yamagetsi chikhoza kuwotcha, mpweya wonyamula katundu ukhoza kuyatsidwa, ndipo chosinthira chachikulu cha thiransifoma chikhoza kugwedezeka.
