I-Resin-insulated Dry-type Transformer SCB18-2000/10
I-Dry transformer iwuhlobo lwe-transformer yamandla ehlukile kune-transformer ecwiliswe ngamafutha, i-transformer ecwiliswe ngamafutha iwukusetshenziswa kwamafutha e-transformer ukuze kuhlanganiswe nokushisa nokushisa, kodwa impahla yokushisa ye-transformer eyomile iwukugxila okwakhiwa ukuthululwa kwe-epoxy resin.
1. I-Iron Core
(1) Isakhiwo sensimbi. Umnyombo wensimbi we-transformer owomile uyingxenye yesifunda kazibuthe, esakhiwe izingxenye ezimbili: ikholomu yensimbi kanye nejoka lensimbi. I-winging ihlanganiswe kukholomu eyinhloko, futhi ijoka lisetshenziselwa ukuvala yonke isifunda kazibuthe. Isakhiwo somgogodla ngokuvamile singahlukaniswa ngezigaba ezimbili: uhlobo oluyinhloko kanye nohlobo lwegobolondo. Umnyombo ubonakala ngejoka lensimbi elibheke phezulu nangaphansi kokusonteka, kodwa alizungezi uhlangothi lokusonteka; I-Shell core ibonakala ngejoka lensimbi elingazungezi nje kuphela izinhlangothi ezingaphezulu neziphansi ze-winding, kodwa futhi izinhlangothi zokusonta. Ngenxa yokuthi isakhiwo esiwumgogodla silula uma kuqhathaniswa, ukwakheka okumazombezombe kanye nokwahlukanisa nakho kuhle kakhulu, ngakho-ke ama-transformer anamandla aseShayina asebenzisa ikakhulukazi umongo, kuphela kwezinye iziguquli ezomile ezikhethekile (njenge-electric furnace dry transformer) ukuze zisebenzise umgogodla wegobolondo.
(2) Insimbi eyinsimbi. Ngenxa yokuthi umgogodla wensimbi uwumjikelezo kazibuthe we-transformer yohlobo olomile, impahla yayo idinga ukungena kahle kazibuthe, futhi ukungena kahle kazibuthe okuhle kuphela okungenza ukulahlekelwa kwensimbi kube kuncane. Ngakho-ke, umgogodla wensimbi we-transformer owomile wenziwe nge-silicon steel sheet. Kunezinhlobo ezimbili zeshidi lensimbi ye-silicon: ishidi lensimbi eligoqiwe elishisayo nelibandayo. Ngenxa yokuthi ishidi lensimbi egoqelwe ngokubanda likwazi ukungena nokungena okuphakeme kanye nokulahlekelwa kweyunithi encane uma lizibuthe lapho lihamba khona, ukusebenza kwalo kungcono kunokweshidi lensimbi eligoqelwe ngokushisayo, futhi ama-transformer asekhaya omile wonke asebenzisa ishidi lensimbi egoqwe ngokubanda le-silicon. Ugqinsi lweshidi lensimbi eligoqiwe elibandayo liyi-0.35, 0.30, 0.27mm nokunye. Uma ishidi likhulu, ukulahlekelwa kwamanje kwe-eddy kukhulu, futhi uma ishidi lincane, i-coefficient ye-lamination incane, ngoba ingaphezulu leshidi lensimbi ye-silicon kufanele limbozwe ungqimba lwepende lokuvikela ukuze lifake ishidi kusuka esiqeshini esisodwa. komunye.
2. Ukuvunguza
I-winding ingxenye yesifunda ye-ome-type transformer, ngokuvamile eyenziwa nge-enameled evaliwe, i-aluminiyamu egoqwe ngephepha noma intambo yethusi ecishiwe.
Ngokusho kokuhlelwa okuhlukile kwama-windings aphezulu naphansi, ama-windings angahlukaniswa abe yi-concentric ne-rhomboid. Ukuze uthole ama-concentric windings, ukuze kube lula ukuhlukanisa phakathi kwe-winding kanye ne-core, i-low-voltage winding ngokuvamile ibekwe eduze nekholomu eyinhloko: kuma-windings agqagqene. Ukuze unciphise ibanga le-insulation, i-low-voltage winding ngokuvamile ibekwe eduze nejoka.
3: I-insulation
Izinto eziyinhloko zokuvikela ngaphakathi kwe-transformer eyomile ngamafutha e-transformer eyomile, amakhadibhodi e-insulating, iphepha lekhebula, iphepha elihlanganisiwe nokunye.
4. Thinta Guqula
Ukuze unikeze i-voltage ezinzile, ukulawula ukugeleza kwamandla noma ukulungisa ukumelana nomthwalo wamanje, kuyadingeka ukulungisa i-voltage ye-transformer eyomile. Njengamanje, indlela yokulungiswa kwe-voltage ye-omile-uhlobo lwe-transformer ukusetha umpompi ohlangothini olulodwa lwe-winding ukuze usike noma ukhuphule ingxenye yamajika amajika ukuze ushintshe inani lokujika kokujika, ukuze kuzuzwe indlela ukulungiswa kwe-voltage okulinganiselwe ngokushintsha isilinganiso se-voltage. Isekhethi lapho i-winding idwetshwa futhi ithintelwe khona ukulawula i-voltage ibizwa ngokuthi i-voltage regulation circuit; Iswishi esetshenziswa ukushintsha ompompi ukulungisa ingcindezi ibizwa ngokuthi i-tap switch. Ngokuvamile, isinyathelo esilandelayo ukudweba empompini efanele kumawindi aphezulu kagesi. Lokhu kungenxa yokuthi i-high-voltage winding ngokuvamile ibekwe ngaphandle, okuholela empompini kulula, okwesibili, i-voltage ephezulu ohlangothini lwamanje incane, ingxenye yamanje ephethe i-lead kampompi kanye nesishintshi sompompi kuncane, futhi ukuthintana ngqo iswishi nayo kungenzeka ukuthi yenziwe.
Ukulawulwa kwamandla kagesi ohlangothini lwesibili lwe-transformer eyomile ngaphandle kokumelana nomthwalo, futhi uhlangothi oluyinhloko luphinde lunqanyulwe kugridi yamandla (akukho ukuvuswa kwamandla), kubizwa ngokuthi umthetho we-voltage ngaphandle kwe-excitation, kanye nomthetho we-voltage onokumelana nomthwalo wokuguqula ukuguqulwa. ukuthepha.
