Ngaba kufuneka sikhethe iGenereyitha yesiGaba esiThathu okanye iJenereyitha enye

Xa sifuna ukuthenga ijenereyitha yedizili, ngaba uya kucinga ukuthenga ijenereyitha yesigaba esithathu okanye ijenereyitha enye?Namhlanje i-Dingbo Power yabelana ngenqaku lokukuvumela ukuba uzifunde.Ndiyathemba ukuba inokukunceda wenze isigqibo.

Elinye lawona malungu abalulekileyo esethi yejenereyitha ye-diesel yijenereyitha yayo, engumatshini onoxanduva lokuguqula amandla omatshini aphambili abe ngamandla ombane, ngokuqhelekileyo ngendlela yokutshintsha kwangoku.Ikwachaza nokuba isethi yejenereyitha ikwinqanaba lesithathu okanye inqanaba elinye, kungakhathaliseki ukuba luhlobo luni lwamafutha kunye nenjini.

Ukuveliswa kwamandla kusekelwe kumthetho kaFaraday, ochaza ukuveliswa kwamandla e-electromotive kwi-conductor ehamba kwindawo yamagnetic.Kwinkqubo yesigaba esisodwa, kukho intsimi yamagnetic ehambayo ngenxa yokujikeleza okwenziwa yi-injini yokutsha yangaphakathi.Umhlaba wemagnethi uya kuveliswa ngezinto ezinozibuthe (okanye oomazibuthe) okanye oomazibuthe ekufuneka banikwe amandla ngumbane oncedisayo wangaphandle.

Nangona kunjalo, kwinkqubo yezigaba ezithathu, ukuveliswa kwamandla kuveliswa ngamacandelo amathathu omagnetic ane-angle ye-120 °, eyenza iipali ezintathu zemagnethi zenkqubo yesigaba sesithathu.Ngenxa yokufika kwetekhnoloji ye-elektroniki yamandla kunye nexabiso eliphantsi kwiminyaka embalwa edlulileyo, sinokufumana iiseti ze-inverter generator kwinqanaba elinye kwimarike.Enyanisweni, ezi iijeneretha zesigaba esithathu .Umguquleli we-elektroniki wongezwa ekupheleni kokuphuma kwamandla ukuguqula isigaba sesithathu sejeneretha kwinkqubo yesigaba esisodwa ngoncedo lwezixhobo zombane.Ngale ndlela, ibonelela ngeenzuzo ze-generator yesigaba sesithathu kunye nokuguquguquka kokuguqulwa kwe-elektroniki.

Ijenereyitha yeSigaba esinye

Uthungelwano lwesigaba esinye ludla ngokusetyenziselwa ukusetyenziswa ekhaya kunye nofakelo olunemigangatho emithathu emincinci kunye neenkonzo.Ngoba?Ngenxa yokuba ukuhanjiswa kwamandla ombane kwisigaba sesithathu se-AC kuphezulu, ukongeza, umphumo we-motor esisiseko kwinkqubo yamanqanaba amathathu ungcono.Yiyo loo nto uninzi lwamagunya afanelekileyo kunye neenkampani zamandla zingavumeli unikezelo lwamandla lwesigaba esinye esidlula i-10KVA.

Ngenxa yesi sizathu, oomatshini besigaba esinye (kubandakanywa neeseti zejeneretha) ngokuqhelekileyo abagqithisi la mandla.Kwezi meko, ii-alternators ezidityanisiweyo zezigaba ezithathu zidla ngokusetyenziswa ukuze zikwazi ukusebenza kwisigaba esinye, nangona oku kuthetha ilahleko enkulu (40% okanye ngaphezulu) ngokuxhomekeke kumzekelo kunye nomenzi we-alternator.

Ukusetyenziswa kwee-alternators zesigaba esisodwa ezidityanisiweyo kwakhona ziqhelekileyo ngenxa yezizathu ezahlukeneyo (ixesha lokuhambisa, uluhlu, njl.).Ukongeza kwinto yokuba i-alternator inokuphinda ixhunywe kwizigaba ezintathu (xa ukufakela kwesigaba sesithathu kutshintsha ngenxa yesizathu esithile), i-alternator isasebenza ngokulinganayo.Ukongeza, ukuba amandla e-injini aphezulu, anokubonelela ngenye indlela kumandla amanqanaba amathathu oqobo.

Injini ye-diesel okanye yepetroli

Ngenxa yokuba zixhaphake kumazinga aphantsi kwamandla, iijenereyitha zesigaba esinye azinamandla kwaye kulula ukusebenza kuneejeneretha zesigaba sesithathu.Ngezi mpawu, abanye oomatshini banokusebenza ngendlela engaqhubekiyo kangangeeyure ezininzi, nto leyo eqhelekileyo kwiinjini eziqhuba ijenereyitha zesigaba esinye.

Kule meko, ukongeza kwiinkqubo zedizili kunye negesi, kunokwenzeka ukufumana iinjini zepetroli kolu luhlu lwamandla amancinci.Ngokubanzi, iijenereyitha zedizili zesigaba esisodwa zenzelwe ukusetyenziswa kwindawo encinci apho kungekho grid yamandla.Ikhaya kunye namashishini afuna iinkqubo zokuxhasa ukubonelela ngamandla xa kukho ukusilela kombane oyintloko zihlala iiyure ezininzi, kuba ukuphuma kombane akufuneki kuhlale ixesha elide ngenxa yobukho benethiwekhi enamandla.

Isigaba sesithathu seseti yejenereyitha yedizili

Iseti yejenereyitha yedizili yesigaba esithathu ngokungathandabuzekiyo sesona sibhengezo esikhulu kolu hlobo lomatshini.Zinokufumaneka phantse kulo naliphi na uluhlu lwamandla, kwaye ukusetyenziswa kwazo kakhulu kunye nokusebenza kakuhle okuqinisekisiweyo kubenza bahlangane ngakumbi, bomelele kwaye basebenze ngakumbi kuneseti ye-generator yesigaba esinye.

Ezi zibonelelo zivela ikakhulu kwi-motor (ijenereyitha), kodwa zikwachaphazela i-injini kwimiba emininzi ehambelanayo.

Iijenereyitha zedizili ezithathu zihlala zixinene ngakumbi kunenqanaba elinye lejenereyitha yedizili kuba inokuzuza kwisiphumo sangoku kunye ne-zero flux, oku kuthetha ukuba intsimbi encinci kunye nobhedu ziyafuneka kwimoto ukuhambisa amandla afanayo.Oku kubenza basebenze ngakumbi ekuveliseni nasekuhanjisweni kwamandla ombane.Ngakolunye uhlangothi, ngenxa yesakhiwo somjikelezo wamagnetic ngokwawo, i-generator ye-diesel yesigaba sesithathu ihlala isebenza kakuhle.

Esinye isiphumo esinokuthi singaziwa kakuhle kukuba iinjini zesigaba esisodwa zineepali ezimbini, ngelixa ii-motor zesigaba sesithathu zineepali ezintathu.Oku kwenza i-torque ifunxwe sisijikelezo sejeneretha esinezigaba ezithathu.Ngoko ke, inkqubo yokuhanjiswa komatshini, iibheringi kunye nezinye izinto azigcini nje ngokugqithiswa, kodwa zilungelelanise ngakumbi.Ukufudumala kwe-friction yee-motor zesigaba sesithathu kuphantsi, okwandisa ukuqina kunye nokunciphisa umsebenzi wokulondoloza.Okukhona i-motor inkulu, kokukhona ibaluleke ngakumbi le miphumo.

Iikhamera ezintathu kwiseti yejenereyitha yedizili ziqinile kwaye zithembekile.Baye bavavanywa ngokupheleleyo ixesha elide kwiimeko ezahlukeneyo kwaye bafumana iziphumo ezilungileyo.Ke ngoko, ziyinxalenye ebalulekileyo malunga nayo nayiphi na iprojekthi enzima: izibhedlele, izixhobo zomkhosi, ii-airports zekhompyuter, njl.

Usebenzisa phi inqanaba lesithathu lejenereyitha yedizili kunye nenqanaba elinye lejenereyitha yedizili?

Iiseti zejenereyitha yedizili yesigaba esinye zidla ngokusetyenziselwa izixhobo ezinombane ophantsi ezingadingi kusetyenziswa kakhulu.Oku kwenza kube lula ukufumana umbane apho kungekho gridi ekhoyo, ukuze kusetyenziswe izixhobo ezincinci zamandla (okanye iinjongo ezifanayo).

Isenokuthi isebenze njengenkqubo yamandla egcinayo kwiiyure ezimbalwa, nje ukuba isetyenziselwa amakhaya okanye amashishini amancinci adla ngokuxhaswa yigridi eyomeleleyo.Oku kuya kuvumela ukufakela ukuba kuqhubeke ukusebenza xa kwenzeka ukungaphumeleli okufutshane okanye ukuqhawula.

Nangona kunjalo, iiseti zejenereyitha ye-diesel yezigaba ezithathu zifanelekile xa zibonelela ngamandla kwimithwalo emikhulu yesigaba esisodwa kunye nesigaba sesithathu, kuba iteknoloji yabo kunye nolwazi lwethu olutyebileyo kubo luhlala luthembekile, lunamandla kwaye lusebenza kakuhle.

Izigaba ezithathu zeeseti zejenereyitha zedizili zisetyenziswa kweyona ndawo imbi kakhulu kunye neemeko mihla le, ukusuka ekusetyenzisweni njengobonelelo lwamandla olulindileyo lweenkqubo zekhompyuter ukuya kwizicelo zomkhosi.Olu hlobo lwe ijenereyitha ibonelela ngemithwalo ebalulekileyo kunye nengxakeko kumazwekazi amahlanu kwihlabathi jikelele.

Nangona kunjalo, imeko yangoku kukutshintsha iiseti zejenereyitha zesigaba esinye kunye nenqanaba lesithathu leseti yejeneretha yedizili, idityaniswa ne-inverter yokuguqula i-elektroniki eguqula unikezelo lwamandla amanqanaba amathathu kunikezelo lwamandla lwesigaba esinye.Ngexesha eliphakathi, iijenereyitha zedizili zesigaba esinye zinokuphela zinyamalale kwaye endaweni yazo kuthatyathwe esi sixhobo, esinexabiso eliphantsi kwaye sithembeke ngakumbi.Nangona yongeza ibakala lombane kwisixhobo, inzima kakhulu.

Ngamafutshane, isethi nganye ye-diesel generator, ingaba isigaba esisodwa okanye isigaba sesithathu, sinendawo yayo yesicelo, exhomekeke kumandla obugcisa benkqubo nganye kunye neenzuzo kunye nokungonakali kweteknoloji nganye.Ukuba ulungiselela ukuthenga iseti yejenereyitha yedizili, ungakufumanela eyona seti yejenereyitha yedizili ekumgangatho ophezulu.
