Cov txheej txheem txuas txuas rau voltage transformers

(1) Ib-theem hluav taws xob, uas tuaj yeem siv los ntsuas cov kab hluav taws xob ntawm lub kaw lus nrog qhov nruab nrab qhov nruab nrab uas tsis ncaj qha hauv av ntawm 35kV lossis qis dua lossis qhov txheeb ze rau hauv av hauv qhov system nrog qhov nruab nrab taw tes uas ncaj qha hauv av. ntawm 110kV lossis siab dua.
(2) V / V thaiv yog txhawm rau txuas lub siab thiab tsis tshua muaj hluav taws xob windings ntawm ob lub siab insulated ib-theem voltage transformers ntawm theem los tsim ib daim duab peb sab tsis tiav. Txoj kev no feem ntau siv nyob rau hauv high-voltage peb-theem systems ntawm 35kV los yog hauv qab no nrog ib tug nruab nrab point uas tsis yog grounded los yog grounded los ntawm ib tug arc suppression kauj, tshwj xeeb tshaj yog nyob rau hauv 10kV peb-theem systems.
(3) Daim ntawv xaim ntawm YN, yn, d0 lossis YN, y, d0, uas yog tsim los ntawm peb theem ib zaug peb-winding voltage transformers, yog dav siv nyob rau hauv 3 ~ 220kV tshuab. Nws qhov thib ob winding yog siv los ntsuas qhov theem-rau-theem voltage thiab tus txheeb ze voltage rau hauv av. Lub auxiliary Secondary winding txuas nrog rau daim duab peb sab qhib rau kev nkag mus rau AC lub zog hluav taws xob hluav taws xob tiv thaiv cov cuab yeej thiab cov relays. Peb-theem tsib-kem hluav taws xob transformer yog siv los hloov cov xaim tsim los ntawm saum toj no peb-theem peb-winding voltage transformers. Tsuas yog cov tub ntxhais hlau, nws daim ntawv yog ib yam nkaus li daim duab 3. Nws feem ntau tsuas yog siv hauv 3 ~ 15kV systems.
(4) Peb-theem peb-winding tsib-kem voltage transformer, nws cov thawj winding thiab lub ntsiab theem nrab winding txuas nrog lub hnub qub, thiab qhov nruab nrab taw tes yog grounded, thiab cov pab cuam thib ob winding txuas rau hauv daim duab peb sab qhib. Yog li, hom hluav taws xob hloov hluav taws xob no tuaj yeem ntsuas kab hluav taws xob thiab qhov sib txheeb ntawm qhov hluav taws xob rau hauv av, thiab cov kev pabcuam thib ob tuaj yeem muab tso rau hauv lub relay thiab cov teeb liab qhia rau AC fais fab kev sib txuas hluav taws xob saib xyuas.
