Demagnetization Njira ndi Ntchito ya 900kw Dizilo jenereta

900kw dizilo jenereta, monga a jenereta yamphamvu kwambiri , ali ndi mphamvu zonse ndi mphamvu zamphamvu.Panthawi imodzimodziyo, monga jenereta ya dizilo, imakhala ndi mawonekedwe a ntchito yosavuta komanso kukonza bwino.Kodi mumadziwa bwanji za njira ya demagnetization ndi ntchito ya jenereta ya dizilo ya 900kw?

Jenereta ya dizilo ya 900kw imakhala yochotsa chisangalalo.

Pogwiritsa ntchito inverter yogwira ntchito ya mlatho wokhazikika wa magawo atatu, mawonekedwe owongolera amasinthidwa kuchoka ku malo okonzera ochepera 90 ° kupita ku ngodya yoyenera kuposa 90 °.Panthawi imeneyi, mphamvu yokoka imasinthidwa ndikugwiritsira ntchito mafunde otsekemera mu mawonekedwe a kumbuyo kwa EMF., The de-excitation process yomwe rotor panopa imawola mwachangu mpaka zero imatchedwa inverter de-excitation.Njira yochepetsera iyi imadyetsa mwachangu chosungira mphamvu ya rotor ku gawo lamagetsi la AC la mlatho wowongolera magawo atatu, ndipo sikutanthauza zoletsa zotulutsa kapena ma grids azimitsa arc.Ndi njira yosavuta komanso yothandiza yochotsera chisangalalo.Chifukwa palibe kukhudzana, palibe arc, ndipo palibe kutentha kwakukulu komwe kumapangidwa, demagnetization ndiyodalirika.Kukula kwa EMF yam'mbuyo, kumapangitsanso kuthamanga kwa demagnetization.The EMF kumbuyo kwaiye pa inversion wa magawo atatu zonse kulamulira mlatho mwachindunji mogwirizana ndi voteji wa AC mbali magetsi, kotero mtengo wa kumbuyo EMF ndi malire pamlingo wakutiwakuti.Nthawi yomweyo, max control max (kapena ang'onoang'ono inverter angle min) amayikidwa kuti ateteze "inverter subversion".Kuchepetsa kwa) kumachepetsanso kumbuyo kwa EMF kumlingo wina.Chifukwa chake, demagnetization ya inverter imodzi imakhala yochepa ndi mphamvu yamagetsi ya AC.Panthawi ya inverter demagnetization, mayendedwe osangalatsa amachepetsa motsatana, koma mtengo wa EMF womwe umagwiritsidwa ntchito panthawi ya inverter demagnetization ndi wocheperako kuposa njira yozimitsa grid demagnetization, chifukwa chake kutsika kwapano Mlingo ndi wocheperako, nthawi ya demagnetization ndi yayitali, koma overvoltage angapo ndi otsika kwambiri.

900kw dizilo jenereta sanali liniya kukana demagnetization.

Dongosolo lachisangalalo likatsekedwa mwachizolowezi, chowongolera chimangochotsa maginito ndi inverter;ngati yatsekedwa mwangozi, kusintha kwa demagnetization kudzalumpha kusamutsa mphamvu ya maginito kupita ku resistor yowononga mphamvu kuti iwonongeke.Jenereta ikakhala kuti ikugwira ntchito molakwika monga kutsetsereka, voteji yokwera kwambiri imapangidwa mudera la rotor.Panthawi imeneyi, ozungulira overvoltage kudziwika wagawo A61 gawo anaika mu ozungulira dera adzazindikira rotor patsogolo overvoltage chizindikiro ndipo nthawi yomweyo Yambani ndi V62 thyristor element, kuphatikiza mphamvu dissipation resistor unit FR mu dera rotor, ndi kuthetsa kwaiye overvoltage mphamvu kudzera. mayamwidwe mphamvu ya mphamvu dissipation resistor;ndi reverse overvoltage chizindikiro cha rotor dera mwachindunji amadutsa V61 yachiwiri chubu Mphamvu dissipation resistor chikugwirizana kuyamwa mphamvu kuonetsetsa kuti jenereta rotor sidzatsegula konse dera, kuti ateteze modalirika kutchinjiriza rotor ku kuwonongeka.Chifukwa cha chitetezo chamtunduwu, mafunde a rotor adzatulutsa mphamvu ya maginito yosiyana, yomwe imatha kuthetsa mphamvu ya maginito yomwe imapangidwa ndi kayendetsedwe kake ka stator, kuteteza pamwamba pa rotor ndi mphete ya rotor. kuyaka moto.

Udindo wa 900kw dizilo jenereta magnetoresistance.

Kuthamanga kwamphamvu kwa a 900kw dizilo jenereta ndi koyilo yokhala ndi inductance yayikulu.M'mikhalidwe yabwinobwino, chisangalalo chapano chimapanga mphamvu ya maginito pa rotor ya jenereta.Pamene jenereta ya dizilo ya 900kw ikulephera mkati, m'pofunika kuti muchepetse mphamvu zowonongeka ndikuchotsa mphamvu yamagetsi ya 900kw dizilo kuti mupewe kukula kwa ngozi.Komabe, ndizovuta kwambiri kugwiritsa ntchito chosinthira kuti mudule mwachindunji pakali pano mudera lotere ndi inductance yayikulu.Chifukwa mwachindunji kudula machiritso panopa kupanga voteji mkulu malekezero onse a malekezero kukokera, amene akhoza kuwotcha lophimba kulankhula.Choncho, musanayambe kudula dera lachisangalalo, choyamba gwirizanitsani kukana kwa de-excitation kumbali zonse ziwiri za rotor mofanana, kotero kuti pamene dera lachisangalalo likudulidwa, kukana kwa de-excitation kumatha kuyamwa mwamsanga mphamvu ya maginito ya maginito othamanga. , kuchepetsa kuthamanga kwa rotor panopa, ndi kuchepetsa rotor self Mphamvu yopangidwa ndi electromotive imasewera ndi cholinga chochepetsera kuwonjezereka kwa rotor ndi demagnetization.

Kukaniza kutulutsa mphamvu si pamene jenereta ya dizilo ya 900kw ikufanana kapena kusinthidwa, koma pamene jenereta ya dizilo ya 900kw ikugwiritsidwa ntchito, chopinga chochotseratu chisangalalo chimalowetsedwa ndikuyikidwa kumapeto onse a koyilo ya rotor. ndi chosinthira chomwe chimagwiritsidwa ntchito kuti muchepetse mwachangu zomwe zikuchitika mudera losangalatsa.Musanayambe kupanga voteji, ikani chosinthira de-excitation.Kukachitika kuti 900kw jenereta ya dizilo yazimitsidwa kapena mwangozi, yendetsani chosinthira chotsitsa kuti muchepetse mphamvu yamagetsi kuti mukwaniritse cholinga chochepetsera mwachangu mphamvu ya 900kw ya jenereta ya dizilo.

zotsatira:

(1) Ndi kuti mwamsanga anadula 900kw dizilo jenereta kukomerera mapiringidzo ndi chisangalalo mphamvu njira.

(2) Kuzimitsa mwachangu mphamvu ya maginito mkati mwa jenereta ya dizilo ya 900kw.
