I-Resin-insulated Dry-type Transformer SCB18-2000/10

I-Dry transformer luhlobo loguqulo lwamandla olwahlukileyo kwi-oyile-untywiliselwa kwi-transformer, i-oyile-intywiliselwe i-transformer kukusetyenziswa kwe-oyile ye-transformer yokugquma kunye nokutshatyalaliswa kobushushu, kodwa i-insulation material ye-transformer eyomileyo ininzi i-insulation eyenziwa yi-epoxy resin yokugalela.

(1) Ubume bentsimbi. Ingundoqo yentsimbi ye-transformer eyomileyo iyinxalenye yesiphaluka samagnetic, esakhiwe ngamacandelo amabini: ikholomu yentsimbi kunye nejoka yentsimbi. I-winding ipakishwe kwikholamu engundoqo, kwaye ijoka isetyenziselwa ukuvala yonke isiphaluka samagnetic. Ulwakhiwo lwesiseko lunokwahlulwa ngokubanzi lube ngamacandelo amabini: uhlobo olungundoqo kunye nohlobo lweqokobhe. Undoqo ubonakaliswe yidyokhwe yentsimbi ngasentla nasezantsi ekujikeni, kodwa ayijikelezi kwicala lokujija; I-Shell core ibonakaliswe yijoka yentsimbi ejikeleze kungekuphela nje phezulu kunye nangaphantsi kwamacala okujikeleza, kodwa kunye namacala okujikeleza. Ngenxa yokuba ulwakhiwo olungundoqo lulula ngokwentelekiso, ubume bokujija kunye nokugquma kukwalungile, ngoko ke amandla aseTshayina aguquguqukayo awomileyo asebenzisa undoqo, kuphela kwiziguquli ezikhethekileyo ezomileyo (ezifana nesiguquli sombane sombane) ukusebenzisa iqokobhe elingundoqo.

(2) Izinto ezingundoqo zentsimbi. Ngenxa yokuba undoqo wentsimbi yisekethe yamagnetic yohlobo olomileyo lwe-transformer, izinto zayo zifuna ukufikeleleka kakuhle kwemagnethi, kwaye kuphela ukugqwesa kwamagnetic kunokwenza ilahleko yentsimbi ibe ncinci. Ngoko ke, ingundoqo yentsimbi ye-transformer eyomileyo yenziwe nge-silicon sheet sheet. Kukho iintlobo ezimbini ze-silicon sheet sheet: eshushu esongwayo kunye neshiti eliqengqelekayo elibandayo. Ngenxa yokuba icwecwe lentsimbi eliqengqelekayo linokungena okuphezulu kunye neyunithi encinci yelahleko xa imagnethi ecaleni kwendlela yokuqengqeleka, ukusebenza kwayo kungcono kunokweshiti lentsimbi eliqengqelekayo, kwaye iziguquli ezomileyo zasekhaya zonke zisebenzisa i-silicon yentsimbi epholileyo. Ubukhulu bephepha lasekhaya elibandayo eliqengqelekayo yi-0.35, 0.30, 0.27mm njalo njalo. Ukuba ishidi lingqindilili, ilahleko yangoku ye-eddy inkulu, kwaye ukuba iphepha lincinci, i-coefficient ye-lamination incinci, kuba umphezulu we-silicone sheet sheet kufuneka ugqunywe ngoluhlu lwepeyinti yokukhusela ukugquma iphepha ukusuka kwisiqwenga esinye. komnye.

I-winding yinxalenye yesiphaluka se-former-type-type transformer, eyenziwa ngokubanzi nge-enameled e-insulated, i-aluminium ehlanganiswe ngephepha okanye i-copper wire.

Ngokwahlukileyo kwilungiselelo le-windings ephezulu kunye nesezantsi, i-windings inokwahlulwa ibe yi-concentric kunye ne-rhomboid. Kwi-concentric windings, ukwenzela ukuba kube lula ukugquma phakathi kwe-winding kunye ne-core, i-low-voltage winding idla ngokubekwa kufuphi nekholamu engundoqo: kwii-windings ezigqithisayo. Ukunciphisa umgama we-insulation, i-low-voltage winding idla ngokubekwa kufuphi nejoka.

Izinto eziphambili zokugquma ngaphakathi kwe-transformer eyomileyo yioli eyomileyo ye-transformer, i-insulating cardboard, i-cable paper, i-corrugated paper kunye nokunye.

Ukuze unikeze i-voltage ezinzileyo, ukulawula ukuhamba kwamandla okanye ukulungelelanisa ukuchasana nomthwalo wangoku, kuyimfuneko ukulungisa i-voltage ye-transformer eyomileyo. Okwangoku, indlela yohlengahlengiso lwamandla ombane wohlobo olomileyo lwe-transformer kukuseta itephu kwelinye icala le-winging ukusika okanye ukonyusa indawo yokujija ukuguqula inani lokujika kokujija, ukuze kuphunyezwe indlela yokujika. uhlengahlengiso lombane ophuculweyo ngokutshintsha umlinganiselo wombane. Isekethe apho i-winding itsalwa kwaye icofa ukulawulwa kwamandla ombane ibizwa ngokuba yi-voltage regulation circuit; Iswitshi esetyenziselwa ukutshintsha itephu ukulungisa uxinzelelo ibizwa ngokuba sisitshixo sempompo. Ngokubanzi, inyathelo elilandelayo kukuzoba impompo efanelekileyo kwi-high voltage winding. Oku kungenxa yokuba i-voltage ephezulu yomoya ihlala ibekwe ngaphandle, ekhokelela kwimpompo ilungile, okwesibini, i-voltage ephezulu yecala langoku incinci, indawo ephetheyo yetephu ekhokelayo kunye netshintshi yempompo incinci, kunye nokunxibelelana ngokuthe ngqo kwetephu. iswitshi kwakhona kusenokwenzeka ukuba yenziwe.

Ulawulo lwamandla ombane kwicala lesibini le-transformer eyomileyo ngaphandle kokuchasana nomthwalo, kwaye icala eliphambili likwanqunyanyisiwe kwigridi yamandla (akukho vuselelo lwamandla), libizwa ngokuba ngummiselo wombane ngaphandle kovuselelo, kunye nolawulo lombane olunokumelana nomthwalo wokuguqula ukujika. ukucofa.
