6-35kV I-Dry type transformer

I-transformer yohlobo olomile

Uchungechunge lwe-SC (B) lwe-6-35KV epoxy resin dry-type transformer isizukulwane esisha semikhiqizo yokonga amandla. Lolu chungechunge lwemikhiqizo ye-transformer yokusabalalisa isetshenziswa ezikhathini ezikhethekile lapho i-voltage ye-transformer iguqulwa ngokuqondile isuka kugridi yamandla engu-6-35KV iye ku-400V ukusatshalaliswa, okunganciphisa izixhumanisi zokudlulisa nokuguqula i-6-35KV, futhi kunciphise kakhulu izindleko zokusebenza nokugcinwa. I-6-35KV level non excitation voltage elawula ukusabalalisa umkhiqizo we-transformer usuphumelele ukuhlolwa futhi usungulwe njengomkhiqizo wobuchwepheshe obuphezulu. Umkhiqizo unezinzuzo zokulahlekelwa okuphansi, ukubambezeleka komlilo okuhle, ukumelana okuqinile kwesiyingi esifushane, usayizi omncane, umsindo ophansi, umbani omuhle nokumelana nokushaqeka kukagesi, nokusabalalisa ukushisa okufanayo. Ngaphezu kwalokho, ngenxa yokuthi ama-epoxy resin-type dry-type awasebenzisi uwoyela we-transformer, ngeke akhiqize ukungcoliswa kwamafutha futhi angabi nayo ingozi yokuqhuma. Umkhiqizo ungasetshenziswa kabanzi njenge-transformer yokusabalalisa yokulungiswa kwesistimu yamandla asemadolobheni, kanye nezikhathi ezihlukahlukene ezifana nezakhiwo eziphakeme kakhulu, izikhumulo zezindiza, iziteshi, amachweba, imigwaqo engaphansi komhlaba, njll. ezinezidingo eziqinile nezikhethekile zokuvikela umlilo kanye nemvelo. isivikelo.

Isakhiwo somkhiqizo:

I-epoxy resin dry-type transformer ikakhulukazi iqukethe i-transformer core, i-transformer winding, i-transformer insulation, i-transformer lead, idivayisi yokupholisa i-transformer, nedivayisi yokulinganisa izinga lokushisa. Ikhoyili ye-transformer yokusabalalisa ilinyazwe emshinini wokugoqa onembile kakhulu, futhi i-low-voltage winding ithatha isakhiwo sokugoqa se-foil. I-transformer enkulu inomgudu wokungenisa umoya, futhi ngemva kokusonteka, iyomiswa nge-vacuum. Inqubo yokuthela kanye nokuqinisa ilandela ngokuqinile izidingo zenqubo ukuze kuqinisekiswe ukuthi awekho amabhamuza noma izimbotshana ngaphakathi kwekhoyili, futhi umkhiqizo we-transformer uzuza ukusebenza kwekhwalithi ephezulu.

Ingqikithi:

Lolu chungechunge lwama-transformer okusabalalisa lukhetha amashidi ensimbi ensimbi ayizibuthe asezingeni eliphakeme futhi aphezulu anozibuthe agingqike njengensimbi, futhi amukela imigqa yokusika yeshidi lensimbi ethuthukisiwe engu-45 ° ethambekele ngokugcwele amashidi okunqwabelanisa. Ikholomu eyinhloko isebenzisa ubuchwepheshe obuthuthukisiwe obufana nokubopha ibhande lamahhala le-F-grade weft kanye nokulungiswa kwepuleti lokudonsa ijoka lensimbi. Ingaphezulu le-iron core limbozwe nge-epoxy resin ukunciphisa umthelela wokuvuza kazibuthe, ukuthuthukisa ngokuphumelelayo ukusatshalaliswa kwesekethe kazibuthe, futhi kunciphise umsindo, ukulahlekelwa okungenamthwalo, kanye nomthamo wamanje we-iron core, Lokhu kuthuthukisa kakhulu ukubukeka kwekhwalithi yemikhiqizo ye-transformer yokusabalalisa.

I-high voltage winding:

I-high-voltage winding ithatha isakhiwo esihlukene futhi esinezingqimba, sinciphisa kakhulu i-voltage ye-interlayer yama-winging. Yakhiwa ngokusakazwa kwe-vacuum nge-epoxy resin egcwele izithasiselo, kunciphisa ukukhishwa kwendawo ngaphakathi kokusonta kanye nokwenza ngcono ukusebenza kukagesi kwekhoyili. I-interlayer yokujikajika kwe-transformer yokusabalalisa yenziwe ngendwangu ye-DMD epoxy resin efakwe ngaphambili ukuze kwandiswe amandla okumelana ne-voltage. Ingaphezulu le-winding ligcwele indwangu ye-fiberglass mesh ukuze kuthuthukiswe amandla omshini wekhoyili futhi kuthuthukise ukumelana kwesekethe emfushane yomkhiqizo we-transformer wokusabalalisa. Ikhoyili ayisoze yaqhekeka.

I-low voltage winding:

I-low-voltage winding isebenzisa isakhiwo se-foil, futhi ikhoyili ithatha i-axial cooling air duct ukuze ithuthukise amandla okukhipha ukushisa. I-interlayer ye-low-voltage winding ye-transformer yokusabalalisa yenziwe ngendwangu ye-DMD epoxy resin efakwe ngaphambili, futhi isiphetho sivalwe nge-epoxy resin, eyenza uxhumano olungaguquki lulonke.

Izici zomkhiqizo

1. I-flame retardant, i-epoxy resin njengento efakwayo yama-SCB ohlobo olomile lwe-transformer ngokwemvelo ibambezela ilangabi futhi ngeke isekele ukuvutha uma kuba nomlilo.

2. Ubufakazi bomswakama nokumelana nothuli, ingaphezulu le-SCB dry-type transformer winding lifafazwa ngopende wobufakazi obuthathu, obungeke buthinte isiguquli sohlobo olomile ezindaweni ezinzima ezifana nothuli nomswakama.

3. Isakhiwo esiqinile, ukujikajika kwe-SCB yohlobo olomile lwe-transformer kuyaphonswa futhi kuqiniswe nge-epoxy resin, enamandla amakhulu emishini kanye nokumelana okuqinile kwesiyingi esifushane.

4. Umthamo wokugcwala oqinile, isiguquli sohlobo olomile lwe-SCB sinezinga lokufaka u-F, izinga eliphezulu lokumelana nokushisa, namandla okusebenza athuthukisiwe angaphezu kwenani elilinganiselwe lomkhiqizo.

5. Ukugcinwa okulungile, i-SCB-type-transformer eyomile ayidingi uwoyela we-transformer, futhi ingamiswa ngokuvula amandla ngemva kokuvala isikhathi eside.
