Ingcaciso yeMveliso

Isiguquli samandla sisetyenziswa ngokubanzi njengemveliso yamandla esisiseko.Kwiminyaka emashumi edlulileyo, i-China kunye nehlabathi lonke sele isebenzise iplagi - kwi-transformer yamandla ixesha elide, iimpawu zayo ezingaphuculwanga.I-S13-M-RL, i-S11-M-RL yochungechunge oluqinileyo lweziguquli zentsimbi ezingundoqo eziphuhliswe yinkampani yethu yenye inguqu eguquguqukayo emva kweplagi kunye neenguqu zentsimbi eziphambili.Luhlobo lwe-transformer enesakhiwo esinengqiqo ngakumbi, ukusebenza okungcono kunye nokonga amandla.

Ngokwakhiwa kunye nokuguqulwa kweegridi zamandla asezidolophini nasezilalini kunye nokuqaliswa kweeprojekthi zamandla ahlukeneyo, indlela yokuphucula umxholo wobugcisa beenguqu zamandla, ukuphumeza ngcono imigaqo-nkqubo yesizwe yolondolozo lwamandla kunye nokukhusela okusingqongileyo, kunye nokukhuthaza ngokusebenzayo iimveliso ezintsha zokugcinwa kwamandla, okuphantsi. ukusetyenziswa kunye nokukhuselwa kokusingqongileyo kube ngumba obalulekileyo kuthi.Isiguquli samandla esingunxantathu esiqinileyo esiphuhliswe yinkampani yethu luhlobo lwesiguquli esisebenzisa izixhobo zemveli kodwa sinengxolo ephantsi yokusebenza, ilahleko ephantsi kunye neempawu ezigqwesileyo zokugcina izinto.Ngokupheleleyo ngokuhambelana noqoqosho lwamazwe ngamazwe kunye nekhaya eliphantsi kwekhabhoni kunye nokugcinwa kwamandla kunye nezikhokelo zokunciphisa ukukhutshwa kunye nemigaqo-nkqubo.Imveliso ibandakanywe kwibhetshi yokuqala yeemveliso zokonga umbane ezikhethwe sisiziko samandla sesizwe samandla;Iiprojekthi zotyalo-mali lohlahlo lwabiwo-mali kulondolozo lwezibonelelo kunye nokukhuselwa kokusingqongileyo kwiKomiti ePhakathi yeQela;Ikhomishini karhulumente yezoqoqosho kunye norhwebo kunye nombutho wangaphambili wegridi karhulumente wase-China upapashe amanqaku akhuthaza le mveliso yokonga umbane;I-Shenyang Substation iphinda ikhuthaze i-iron transformer engunxantathu njengemveliso yokutshintshwa kweplagi kunye ne-flat winding core transformer yamandla.

Eyahlukileyo "Core"

Unxantathu wentsimbi engundoqo ayifuni ukuba igawulwe okanye ibethelwe, iphelisa i-transverse kunye ne-longitudinal joints of transformers zemveli, ukunciphisa ukuxhathisa kazibuthe;icandelo elinqamlezileyo londoqo wentsimbi lingqukuva, ngoko ke i-coefficient yokuzalisa yombindi wentsimbi inkulu, unxantathu wesakhiwo esiqinileyo senza isigaba saso sesithathu sesekethi yamagnetic ilingane kwaye imfutshane, iqonda ubume bentsimbi yesiguquli esifanelekileyo sabantu.

Undoqo wentsimbi ongunxantathu wenziwa ngamabhanti entsimbi aqhubekayo ukusuka kumxinwa ukuya kububanzi aze abanzi ukuya kumxinwa.Phelisa iicore ezintathu zangaphakathi ezinecandelo elinqamlezayo lisisangqa, uze emva koko unqumle iicore ezintathu ezingaphakathi ngokuqinileyo, wenze iintsimbi ezintathu ezinqamlezileyo eziphantse zibe setyhula.I-loop yamagnetic yesigaba sesithathu i-symmetrical ngokugqibeleleyo kwaye ilingana, ukunciphisa ijoka yentsimbi, i-coefficient ephezulu yokuzalisa i-coefficient, isakhiwo sayo sisakhiwo esilungileyo soguqulo esaziwayo ngokubanzi.Ayinakufaniswa nondoqo ojikajikayo othe tyaba.Idatha nganye yovavanyo lukanxantathu oqinileyo ojikelezayo oguqukayo wamandla ungcono kunesiguquli samandla esisicaba.I-Triangle eqinileyo yokujija ingundoqo kukuphumelela okukhulu kunye nokutsiba kumbindi wentsimbi wesiguquli samandla.Ukuzalwa kwayo kwanconywa "njengenguqu kumbindi wentsimbi weziguquli zamandla".Ke, unxantathu oqinileyo onamagingxigingxi angundoqo oguquguqula amandla abonwa ukonga amandla, ukhuseleko lokusingqongileyo, isiguquli samandla esiluhlaza esithe cwaka.

Inzuzo yokusebenza

Isiguquli esiqinileyo sentsimbi esaphula ukwakheka kweplani yemveli, samkela unxantathu oqinileyo, sisenza indibaniselwano esengqiqweni ngakumbi yeentsimbi zentsimbi ngokugqobhoza izakhelo ezintathu ezifanayo ngokupheleleyo.Izigaba ezithathu zeesekethe zemagneti zilungelelene kwaye ziyafana ngobude, ziqinisekisa ibhalansi yonikezelo lwamandla ngezigaba ezithathu, zinciphisa ukuxhathisa kwemagnethi kakhulu, kwaye zinciphisa intsimi yangoku, akukho mthwalo ulahlekileyo kakhulu.Ngaloo ndlela amandla omatshini aphezulu, isakhiwo sizinzile.

Iimpawu eziluncedo njengoko kungezantsi

1.Nciphisa akukho-mthwalo ngoku kunye nelahleko kakhulu.

I-2.Isigaba sesithathu sesekethi yamagnetic ilungelelene, akukho i-harmonic yesithathu, i-output waveform yi-sinusoidal, kwaye iqinisekisa umgangatho wokunikezelwa kwamandla ombane.

3.Ingxolo ephantsi: Undoqo wentsimbi uvuthuzwa rhoqo kwaye ngokuchanekileyo kumatshini okhethekileyo wokujija ngamacu etrapezoid atshintsha ububanzi rhoqo.Akukho mthungo, unokusombulula ingxolo ye-laminated core ebangelwa ukungahambi kakuhle kweesekethe zemagneti.

I-4.Inokusasazwa kobushushu obulungileyo: ngenxa yobuninzi obuncinci obungenamthwalo, ilahleko ephantsi yokungabikho komthwalo, ixabiso le-calorific ye-iron core liphantsi.I-Adopt D yohlobo lwe-semicircular yedyokhwe yentsimbi kunye ne-pie-inxeba eliqhubekayo eliphezulu-ukujika kwamandla ombane, lenze isakhiwo sokuchitha ubushushu esizijikelezileyo ngokufanelekileyo kunye nokuphuma komoya okuthe nkqo kunye nokuchitha ubushushu bangaphakathi nangaphandle.

I-5.Ubungakanani obuncinci: i-coefficient yokusetyenziswa kwendawo ephezulu, i-transformer ithatha isakhiwo sikanxantathu, ngoko ke umthamo uncinci kune-transformer eqhelekileyo, i-compact kwisakhiwo, intle ngokujonga ngaphandle, igubungela indawo encinci.

I-6.I-iron core kunye ne-coil ye-slid winding iron core transformer yinto yonke, i-iron core ayiyi kukhululeka, kwaye i-coil ayinakukhutshelwa ngaphandle, inomsebenzi omhle wokulwa nobusela.
