Njira yopangira zingwe zamagetsi amphepo
Mphamvu ya mphepo yakhala mzati wofunikira kwambiri pakusintha kukhala mphamvu yoyera. Kumbuyo kwa ma turbine amphepo ataliatali ndi masamba awo ozungulira pali zomangamanga zamagetsi zovuta zomwe zimatsimikizira kugawidwa bwino komanso kotetezeka kwa magetsi opangidwa. Chimodzi mwazinthu zofunika kwambiri ndi chingwe. Ma waya amagetsi amphepo si "oyendetsa magetsi wamba," koma amapangidwira makamaka kuti athe kupirira nyengo yoipa kwambiri, kugwedezeka, kuyenda kwamphamvu, komanso kuwonetsedwa ndi madzi amchere m'ma turbine akunja. Nkhaniyi ikufotokoza njira zopangira ma waya amagetsi amphepo, kuyambira pakupanga mpaka kuyesa kwabwino.
1. Kumvetsetsa zofunikira pakugwiritsa ntchito ma turbine amphepo
Kupanga mawaya kusanayambe, opanga mawaya amachita kafukufuku wa zosowa zawo kutengera komwe chingwecho chili komanso momwe chimagwira ntchito. Mu makina amphamvu a mphepo, mawaya nthawi zambiri amagawidwa m'magulu angapo: mawaya omwe ali mkati mwa nacelle (nyumba ya jenereta), mawaya omwe ali pa nsanja, mawaya a pitch ndi yaw system (blade angle ndi turbine orientation), ndi mawaya omwe ali pakati pa turbine ndi substation (mawaya olumikizana ndi otumizira kunja, makamaka m'mafamu amphepo a m'mphepete mwa nyanja).
Gulu lililonse lili ndi zofunikira zosiyanasiyana. Zingwe zomwe zimadutsa pa nsanja ziyenera kupirira katundu wamakina ndi kukangana. Zingwe zopota/zoyamwa ziyenera kupirira kupindika ndi kugwedezeka mobwerezabwereza. Zingwe zakunja ziyenera kupirira kusintha kwa UV, ozone, chinyezi, ndi kutentha. Pa ntchito za m'mphepete mwa nyanja, kukana dzimbiri la m'nyanja ndi chitetezo ku kulowa kwa madzi ndizofunikira kwambiri. Gawo losanthulali limasankha kapangidwe ka kondakitala, zinthu zotetezera kutentha, mtundu wa chophimba, zida zankhondo, ndi kusankha jekete lakunja.
2. Kapangidwe kaukadaulo: ma conductor, insulation, ndi kapangidwe ka chingwe
Pambuyo poti zofunikira zalembedwa, gulu la mainjiniya limapanga zofunikira pa chingwe. Kusankha kwa zinthu zoyendetsera nthawi zambiri kumakhala pakati pa mkuwa (Cu) ndi aluminiyamu (Al). Mkuwa umakhala ndi mphamvu yoyendetsera bwino komanso kusinthasintha kwabwino, zomwe zimapangitsa kuti ukhale wofala pa zingwe zowongolera, zingwe zolumikizira, ndi zingwe zomwe zimasunthidwa. Aluminiyamu ndi yopepuka komanso yotsika mtengo, nthawi zambiri imagwiritsidwa ntchito mu zingwe zamagetsi zazikulu zotumizira.
Zina zofunika kwambiri ndi izi:
- Malo odutsa gawo la kondakitala (mm²) kuti adziwe mphamvu yonyamulira magetsi.
– Voltage yokha (monga 0,6/1 kV ya zingwe za LV, 6–35 kV ya MV).
- Kalasi yosinthasintha ya conductor, makamaka pa zingwe zosinthasintha.
- Zipangizo zotetezera kutentha monga XLPE (cross-linked polyethylene), EPR/HEPR, kapena PVC yapadera.
- Chishango cha maginito (chotchingira) cha zingwe za MV kuti ziwongolere magetsi.
– Zida (waya wachitsulo kapena tepi yachitsulo, kapena zida za waya wa aluminiyamu) zotetezera makina, makamaka zingwe zapansi panthaka/za m'madzi.
– Jekete lakunja (monga PE, LSZH, kapena polyurethane/PU) loteteza ku kukwawa ndi kukana nyengo.
Kapangidwe kameneka kayenera kutsatira miyezo yamakampani ndi zofunikira za satifiketi, monga IEC/EN, ndi mafotokozedwe enieni a wopanga turbine (OEM).
3. Njira yojambulira waya
Gawo lopanga zinthu zakuthupi nthawi zambiri limayamba ndi zipangizo zopangira zitsulo zopangidwa ndi mkuwa kapena aluminiyamu. Kenako ndodozo zimakokedwa kudzera m'madiresi angapo kuti zipeze waya wocheperako wofunikira. Njira imeneyi imatchedwa kujambula waya.
Pakujambula, waya umasinthidwa ndi pulasitiki ndipo umatha kutentha, zomwe zimapangitsa kuti mafuta azigwiritsidwa ntchito komanso kutentha kuyende bwino. Pa mkuwa, njira yothira (yotenthetsera yolamulidwa) nthawi zambiri imagwiritsidwa ntchito kuti waya ukhale wofewa komanso wosalimba kwambiri. Zotsatira zake zimakhala mawaya opyapyala okhala ndi mainchesi ofanana, omwe ndi zinthu zofunika kwambiri popanga kondakitala.
4. Kupanga kwa kondakitala (kulumikiza chingwe)
Mawaya okokedwawo amaphatikizidwa kukhala kondakitala imodzi kudzera mu njira yolumikizira chingwe. Pali njira ziwiri zazikulu:
– Wayawo umakhala wozungulira mozungulira, ndipo umakhala wozungulira m'magawo.
- Kumangirira chingwe, kusinthasintha, koyenera kugwiritsa ntchito zomwe zimasuntha/kugwedezeka nthawi zambiri.
Pa zingwe za turbine ya mphepo, kulumikiza chingwe chosinthasintha nthawi zambiri kumasankhidwa pazigawo zosinthasintha, monga njira yopita ku dongosolo la pitch. Munjira iyi, makina olumikizira chingwe amapotoza ndikuluka waya ndi pitch inayake (kutalika kwa coil). Pitch yoyenera ndi yofunika kwambiri kwa kondakitala wamphamvu koma wosinthasintha. Kondakitala akamaliza, kuyesa kukana kwamagetsi nthawi zambiri kumachitika kuti atsimikizire kuti conductivity ikugwirizana ndi zofunikira.
5. Kutulutsa kwa insulation: kuphimba ndi kuteteza woyendetsa
Kenako ma conductor amalowa mu mzere wotulutsira kutentha, womwe ndi njira yophikira ma conductor ndi zinthu za polima pogwiritsa ntchito chotulutsira kutentha. Zipangizo zodziwika bwino zotulutsira kutentha pamakina amagetsi amphepo ndi XLPE kapena EPR chifukwa cha kukana kutentha komanso mphamvu zabwino za dielectric.
Mu zingwe za MV, njira yotetezera kutentha imatha kukhala ndi zigawo zingapo:
1. Chotchingira kondakitala (chosasuntha mpweya) kuti chizisalala mphamvu yamagetsi pamwamba pa kondakitala.
2. Chotetezera kutentha (XLPE/EPR) ngati chotetezera kutentha chachikulu.
3. Chotchingira chotetezera kutentha (semiconductor) kuti chiwongolere mphamvu yamagetsi ndikuthandizira kukhazikitsa chotchingira chachitsulo.
Kulamulira makulidwe a insulation ndikofunikira kwambiri. Kuchepa kwambiri kumawopseza kuwonongeka kwa magetsi, pomwe kukhuthala kwambiri kumawonjezera mtengo ndipo kumapangitsa kuti chingwecho chisasunthike. Kuziziritsa pambuyo potulutsa madzi kumachitika pang'onopang'ono, nthawi zambiri pogwiritsa ntchito chidebe chamadzi cholamulidwa ndi kutentha kuti tipewe zolakwika pazinthu (zopanda kanthu, thovu, kapena ming'alu).
6. Kuyika chinsalu ndi chishango
Pa zingwe za mamita ambiri (MV) ndi zingwe zina zowongolera zomvera, chophimba chachitsulo (nthawi zambiri cha mkuwa) chonga tepi kapena waya chimagwiritsidwa ntchito. Chophimbacho chimagwira ntchito ngati njira yolumikizira mafunde olakwika ndipo chimagwira ntchito ngati chishango chamagetsi. Pa zingwe zomwe zili m'malo okhala ndi zida zamagetsi zambiri, kuteteza kumathandiza kuchepetsa kusokoneza.
Njira yokhazikitsa chinsalu imachitika pogwiritsa ntchito makina ojambulira kapena oluka. Kuchuluka kwa nsalu, kuphatikizika kwa tepi, ndi kupitirira kwa chinsalu zimayesedwa kuti zitsimikizire kuti zikukwaniritsa zofunikira zachitetezo ndi kugwirizanitsa kwamagetsi (EMC).
7. Zida: chitetezo chamakina pa matenda oopsa
Pa zingwe zomwe zili pachiwopsezo cha kupsinjika kwakukulu kwa makina—monga zingwe zapansi pa nthaka kapena za pansi pa nyanja—zida zankhondo zimawonjezeredwa. M'makina akunja, zida zankhondo nthawi zambiri zimakhala zofunikira chifukwa chingwecho chiyenera kupirira kupsinjika kwa kuyika, kugundana, komanso kuwonongeka komwe kungachitike chifukwa cha anangula kapena kukangana kwa pansi pa nyanja.
Zida zingakhale:
- Chida choteteza waya chachitsulo (SWA) kuti chikhale ndi mphamvu yolimba kwambiri.
- Chida choteteza tepi chachitsulo (STA) kuti chiteteze ku kupsinjika.
- Zida zotetezera waya za aluminiyamu m'mapangidwe ena kuti achepetse chiopsezo cha dzimbiri la galvanic.
Chida choteteza chimayikidwa pogwiritsa ntchito makina apadera omwe amalumikiza waya/tepi nthawi zonse. Pambuyo pake, nthawi zambiri amawonjezeredwa kuti chitetezocho chisawononge zigawo zapansi.
8. Kutulutsa jekete lakunja: nyengo, UV ndi kukana mankhwala
Gawo lotsatira ndi kutulutsa jekete lakunja (chidendene). Mu ma turbine amphepo, jekete lakunja liyenera kukhala lotha kupirira:
- kuwala kwa UV (makamaka m'mphepete mwa nyanja),
- ozoni ndi nyengo yoipa kwambiri,
- chinyezi chambiri ndi kuzizira,
- mafuta ndi zodzola zina zomwe zili mu nacelle,
- kusweka chifukwa cha kugwedezeka kapena kukangana.
Zipangizo za jekete nthawi zambiri zimakhala PE (polyethylene) kuti zisawonongeke ndi nyengo, LSZH (low smoke zero halogen) kuti zisawonongeke ndi moto m'malo otsekedwa, kapena PU kuti zisawonongeke kwambiri pakugwiritsa ntchito mphamvu. Zizindikiro (khodi ya chingwe, kukula, mphamvu yamagetsi, chaka chopangidwa, ndi muyezo) zimagwiritsidwanso ntchito pagawoli.
9. Kuyesa kwabwino ndi satifiketi
Ma waya amagetsi amphepo ayenera kuyesedwa m'mafakitale osiyanasiyana (mayeso achizolowezi ndi mayeso amtundu). Mayeso ena ofala ndi awa:
- Kuyesa kukana kwa kondakitala ndi kuyang'ana kukula kwake.
- Kuyesa kwamphamvu kwamagetsi (hipot) kuti muwonetsetse kuti chotenthetsera sichinasweke.
- Kuyesa kutulutsa pang'ono (MV yokha) kuti mupeze zolakwika zazing'ono mu insulation.
- Mayeso a kukoka, kupindika, kupotoza, ndi kutopa kwa zingwe zosinthasintha.
- Kuyesa kukalamba kwa kutentha, kukana kwa UV, komanso kukana madzi/chinyezi.
– Pa zingwe za pansi pa madzi: mayeso olowera m'madzi, kukana dzimbiri, komanso nthawi zina mayeso okakamiza.
Ngati chingwecho chapangidwira ntchito inayake, wopanga amakonzanso zikalata zofufuzira zinthu zopangira, malipoti oyesera, ndi zikalata zosonyeza kuti zinthuzo zikugwirizana ndi miyezo yofunikira.
10. Kulongedza, kusungira ndi kutumiza kumalo a polojekiti
Pambuyo poyesa, chingwecho chimakulungidwa pa ng'oma yamatabwa kapena yachitsulo ya mainchesi enaake kuti chisapindike kwambiri. Pa zingwe zazitali, monga zingwe zotumizira kunja kwa dziko, kutumiza kumatha kuchitika pogwiritsa ntchito zombo zapadera zokhala ndi makina ozungulira. Kusunga kumafunanso kusamala kwambiri kutentha, kuwala kwa dzuwa mwachindunji, komanso malo a ng'oma kuti chingwecho chisapindike.
Njira zogwirira ndi kukokera chingwe pamalopo ndizofunikira kwambiri pa moyo wake. Ngakhale zingwe zapamwamba zimatha kuwonongeka ngati radius yopindika yapitirira, mphamvu yapitirira, kapena ngati mapeto a chingwe sanakhazikitsidwe bwino, zomwe zimathandiza kuti chinyezi chilowe mu kapangidwe ka chingwecho.
Kutseka
Njira yopangira zingwe za makina amphamvu a mphepo imaphatikiza uinjiniya wa zipangizo, kuwongolera bwino khalidwe, ndi kapangidwe kogwirizana ndi malo ogwirira ntchito a turbine. Kuyambira kujambula mawaya, kulumikiza zingwe, kutulutsa zotenthetsera, kuyika pazenera, zida, komanso ngakhale jekete lakunja, gawo lililonse limagwira ntchito yofunika kwambiri pakuwonetsetsa kuti chingwecho chingathe kutumiza mphamvu mosamala, moyenera, komanso molimba. Pamene mafamu amphepo akumtunda ndi akumtunda akukula, kufunikira kwa zingwe zodalirika, zosinthasintha, komanso zolimba kudzapitirira kukula—kupangitsa ukadaulo wa zingwe kukhala chinsinsi cha kupambana kwa mphamvu ya mphepo mtsogolo.
