Ua ntej tshaj plaws, cia peb paub qhov txawv ntawm tsib txoj hauv qab no:
1/Dry-type transformers thiab ntub-type transformers muab faib ua theem:
1) Ib-theem transformer: siv rau ib-theem load thiab peb-theem transformer teeb.
2) Peb-theem transformer: siv rau qhov nce thiab poob voltage ntawm peb-theem system.
2/Dry-type transformers thiab ntub-type transformers raug faib raws li txoj kev txias:
1) Qhuav hom transformer: cia siab rau cua convection rau txias, feem ntau yog siv rau hauv zos teeb pom kev zoo, hluav taws xob circuits thiab lwm yam me me transformers.
2) Roj-immersed transformer: cia siab rau cov roj raws li qhov nruab nrab cua txias, xws li roj-immersed nws tus kheej-txias, roj-immersed cua txias, roj-immersed dej txias, yuam roj ncig, thiab lwm yam.
3/ Qhuav-hom transformers thiab ntub-hom transformers raug faib raws li lawv siv:
1) Fais fab transformer: siv rau qhov nce thiab poob voltage ntawm cov kis tau tus mob thiab tis system.
2) Cov cuab yeej transformers: xws li voltage transformers, tam sim no transformers, ntsuas ntsuas thiab relay tiv thaiv pab kiag li lawm.
3) Test transformer: Nws tuaj yeem tsim hluav taws xob siab thiab nqa tawm high voltage test transformer ntawm cov khoom siv hluav taws xob.
4) Tshwj xeeb transformers: xws li hluav taws xob rauv transformers, rectifier transformers, hloov transformers, thiab lwm yam.
4/Dry-type transformer thiab ntub transformer muab faib ua cov ntaub ntawv winding:
1) Ob chav winding transformer: siv los txuas ob theem voltage hauv lub zog hluav taws xob.
2) Peb-winding transformer: feem ntau siv nyob rau hauv lub regional substation ntawm lub hwj chim system, txuas peb voltage theem.
3) Autotransformer: siv los txuas cov tshuab hluav taws xob nrog cov hluav taws xob sib txawv. Nws kuj tseem siv tau los ua ib qho yooj yim kauj ruam-up lossis kauj ruam-down transformer.
