IFiziksi eNgemva kokuSebenza kweSiguquli soMbane oPhezulu

Ngaba ukhe wazibuza ukuba zisebenza njani iziguquli zombane eziphezulu ukunika amandla izixeko zonke okanye oomatshini bomzi-mveliso? Ifiziksi esemva kwezi ziguquli intsonkothile, ibandakanya imigaqo ye-electromagnetism, induction, kunye nokudluliselwa kwamandla. Kweli nqaku, siza kugocagoca kwihlabathi elinomdla lokusebenza kwesiguquli samandla ombane aphezulu ukuqonda isayensi emva kokusebenza kwabo.

Iziseko zoGuqulo lwaMandla oMbane oPhezulu

Iziguquli zamandla ombane aphezulu ziyinxalenye ebalulekileyo yothutho lwamandla kunye neenkqubo zokusasaza. Banoxanduva lokunyusa amandla ombane ombane oveliswa kwimizi-mveliso yombane ukuze bawudlulise umgama omde ngokufanelekileyo baze bawubeke phantsi ukuze usasazwe ngokukhuselekileyo kumakhaya nakumashishini. Umgaqo osisiseko emva kokusebenza kwabo kukungeniswa kwe-electromagnetic, evumela ukuhanjiswa kwamandla ombane ukusuka kwesinye isekethe ukuya kwenye ngommandla wamagnetic.

Kwisiguquli samandla ombane aphezulu, kukho iikhoyili ezimbini zocingo, ezaziwa ngokuba ziindawo ezijikajikayo eziziiprayimari kunye nezesekondari, ezisongelwe kumbindi owenziwe ngentsimbi okanye ngentsimbi. Xa i-alternating current (AC) iqukuqela kumoya ojikajikayo, yenza imagnethi eyahluka-hlukeneyo kumbindi. Olu tshintsho lwemagnethi lubangela amandla e-electromotive kwi-winding yesibini, okukhokelela ekugqithisweni kwamandla ukusuka kwisekethe yokuqala ukuya kwisekethe yesibini.

Umlinganiselo wenani lokujika kwi-windings ephambili kunye neyesibini inquma umlinganiselo wokuguqulwa kombane we-transformer. Umzekelo, ukuba ujiko oluphambili lunamajiko ali-100 kwaye ujiko lwesibini lunamajiko angama-200, i-transformer iya kunyusela umbane ngokuphindwe kabini. Ngokwahlukileyo, ukuba i-winding yesibini ine-50 turns, i-voltage iya kuhla nge-factor of two. Lo mgaqo usisiseko uvumela iinguqu zamandla ombane aphezulu ukuba zilawule ngokufanelekileyo kwaye zidlulise amandla ombane kumanqanaba ombane ahlukeneyo.

Indima yeInsulation kunye nokuPholisa

Iziguquli zamandla ombane aphezulu zisebenza kumandla aphezulu, nto leyo enokukhokelela ekuqhawukeni kombane kunye nokungaphumeleli kokugquma kombane ukuba akuthathwa amanyathelo okhuseleko afanelekileyo. Ukuthintela oku, i-windings kunye nezinye izinto zombane ze-transformer zifakwe kwi-insulated kunye nezinto ezikhethekileyo ezifana ne-oyile yamaminerali, iphepha, kunye neenkqubo ze-insulation composite. Ezi zixhobo zibonelela ngamandla e-dielectric kunye nokuzinza kwe-thermal, ukuqinisekisa ukuba i-transformer inokumelana ne-voltages ephezulu kunye nemisinga ngaphandle kokunikezela ukusilela kombane.

Ukongeza kwi-insulation, iinkqubo zokupholisa zibalulekile ekugcineni ubushushu obufanelekileyo bokusebenza kweziguquli zombane ophezulu. Ukuhamba ngokuqhubekayo kwamandla ombane ngokusebenzisa i-windings kuvelisa ukushisa, okufuneka kuchithwa ukuze kuthintelwe ukushisa kunye nomonakalo kwi-transformer. Iindlela zokupholisa eziqhelekileyo ziquka iinkqubo zokucwiliswa kweoli, apho i-transformer ifakwe kwi-tank ye-oyile ye-insulating ethatha kwaye ikhuphe ubushushu, kunye neenkqubo zokupholisa umoya okanye amanzi anyanzelekileyo, apho iifeni okanye amanzi ajikelezayo anceda ukususa ukushisa okukhulu.

Ukufakelwa okufanelekileyo kunye nokupholisa kubaluleke kakhulu ekusebenzeni okuthembekileyo nokukhuselekileyo kwee-voltage eziphakamileyo, njengoko ziqinisekisa ukunyaniseka kwamacandelo ombane kunye nokuthintela ukuthotywa kwe-thermal phantsi kweemeko zomthwalo onzima.

Impembelelo yoYilo olungundoqo kuMsebenzi

Undoqo wesiguquli sombane ophezulu udlala indima ebalulekileyo ekusebenzeni kwayo kukonke kunye nokusebenza kwayo. Undoqo ubonelela umendo wokuqukuqela kazibuthe oveliswe kukujikoza okuphambili, okuwuvumela ukuba udityaniswe nokujika kwesibini kunye nokuququzelela ukuhanjiswa kwamandla. Ukunciphisa ilahleko yamandla kunye nokwandisa ukusebenza kakuhle, ii-cores ze-transformer zakhiwa kusetyenziswa izinto ezinobuchwephesha obuphezulu bemagnethi kunye ne-hysteresis ephantsi kunye nelahleko yangoku ye-eddy.

Ngokwesiko, ii-cores ze-transformer zenziwe nge-silicone elaminethiweyo yentsimbi, enika iimpawu ezintle zamagnetic kunye nokunciphisa ilahleko yangoku ye-eddy ngenxa yeempawu zayo zokukhusela. Nangona kunjalo, ukuqhubela phambili kwizinto ezingundoqo kunye noyilo kukhokelele kuphuhliso lwe-amorphous kunye ne-nanocrystalline alloys, ebonisa ilahleko ephantsi kunye nokusebenza okuphezulu. Ezi mathiriyeli ziluncedo ngakumbi kwiinguqu zamandla ombane aphezulu ezisetyenziswa ekusetyenzisweni kombane kunye nokuhambelana nokusingqongileyo.

Ukongeza kwizinto eziphambili, ukuyila kwengundoqo ngokwayo kuchaphazela ukusebenza kakuhle kwe-transformer. Iimilo ezingundoqo ezifana ne-E-core, i-I-core, kunye ne-shell-type core zilungiselelwe umbane okhethekileyo kunye nokulinganisa amandla, ngokuqwalasela ukunciphisa ukuvuza kwemagnethi kunye nokwandisa ukuhanjiswa kwamandla. Ngobunjineli ngononophelo uyilo olungundoqo kunye nokukhetha izixhobo ezifanelekileyo, ii-voltage eziguquguqukayo eziphezulu zinokufikelela kumanqanaba aphezulu okusebenza kunye nokusebenza kwiinkqubo ezahlukeneyo zombane.

Ukulawulwa kunye noLawulo lweZiguquli zoMbane oPhezulu

Ukusebenza kwee-high-voltage transformers kufuna ulawulo oluchanekileyo kunye nolawulo lokuqinisekisa ukuhanjiswa kwamandla okuzinzile nokuthembekileyo kunye nokuhanjiswa. Enye yeendlela eziphambili zokulawula i-voltage ye-transformer output ngokusebenzisa i-tap changeers, evumela ukulungiswa komlinganiselo wokujika kwe-transformer ukuhlawulela ukuhluka kwi-voltage yegalelo okanye iimeko zomthwalo.

Iziguquli zempompo zisetyenziswa njengezixhobo zoomatshini okanye zombane ezenza udibaniso lwamanqaku ahlukeneyo ecaleni kojiko lokuqala okanye lwesibini ukulungelelanisa inani elisebenzayo lokujika. Esi sixhobo senza ukuba i-transformer ikwazi ukujongana nokuguquguquka kwamandla ombane wegalelo ukusuka kwigridi yamandla okanye utshintsho kwi-voltage ephumayo efunwa ngumthwalo, ukugcina amanqanaba ombane afunekayo ukuze usebenze kakuhle.

Ukongeza kwiziguquli zetephu, iziguquli zamandla ombane aphezulu zinokubandakanya i-voltage kunye nezinzwa zangoku, iireyilayi ezikhuselayo, kunye neenkqubo zokulawula ukujonga nokulawula ukusebenza kwazo. Ezi zixhobo zibonelela ngengxelo yexesha langempela kwiimeko zokusebenza ze-transformer, ezivumela ukufunyanwa kweziganeko ezingaqhelekanga ezifana nokugqithisa, iisekethe ezimfutshane, okanye ukuchithwa kwe-insulation. Ngokudibanisa iindlela zokulawula ezihlakaniphile kunye nokukhusela, i-voltage ephezulu ye-voltage inokugcina ukusebenza ngokukhuselekileyo kunye nokusebenza kakuhle ngelixa inciphisa umngcipheko weempazamo zombane kunye nexesha lokunciphisa.
