Kev Siv Hluav Taws Xob Hluav Taws Xob Transformer
Cov txheej txheem sib txuas ntawm cov hluav taws xob transformers yog raws li hauv qab no:
(1) Ib leeg-theem thaiv siv tau los ntsuas cov kab hluav taws xob ntawm 35kV thiab hauv qab cov tshuab uas tsis ncaj qha hauv av ntawm qhov nruab nrab lossis theem - mus rau- av voltage ntawm systems saum toj no 110kV uas ncaj qha grounded ntawm qhov nruab nrab point.
(2) V / V thaiv yog txhawm rau txuas qhov siab thiab qis hluav taws xob windings ntawm ob lub siab insulated ib leeg -theem voltage transformers ntawm theem los ua ib daim duab peb sab tsis tiav. Txoj kev no feem ntau yog siv nyob rau hauv high-voltage peb-theem systems ntawm 35kV thiab hauv qab no qhov chaw nruab nrab tsis yog grounded los yog grounded los ntawm lub arc suppression coil, tshwj xeeb tshaj yog nyob rau hauv peb-theem 10kV system.
(3) Daim ntawv xaim ntawm YN, yn, d0 lossis YN, y, d0 yog tsim los ntawm peb ib zaug -theem peb- winding voltage transformers, uas tau dav siv nyob rau hauv 3220kV systems, thiab lawv cov windings thib ob yog siv los ntsuas theem - mus rau -theem voltage thiab theem- mus rau - hauv av. Voltage, auxiliary Secondary windings txuas nrog rau hauv daim duab peb sab qhib rau kev nkag mus rau AC lub zog daim phiaj hluav taws xob xyuas cov cuab yeej thiab cov relays. Ib qho peb-theem tsib-kem voltage transformer yog siv los hloov cov xaim uas muaj saum toj no peb ib zaug -theem peb- winding voltage transformers. Tsuas yog cov tub ntxhais hlau, nws daim ntawv yog qhov pib zoo ib yam li hauv daim duab 3, thiab nws feem ntau tsuas yog siv rau 315kV systems.
(4) Rau peb theem -theem peb-winding tsib-kem voltage transformer, thawj winding thiab lub ntsiab theem nrab winding txuas nrog lub hnub qub duab, thiab qhov nruab nrab point yog grounded , thiab lub auxiliary secondary winding txuas nrog rau hauv daim duab peb sab qhib. Yog li ntawd, hom hluav taws xob hloov hluav taws xob no tuaj yeem ntsuas cov kab hluav taws xob thiab theem - mus rau - hauv av voltage, thiab cov auxiliary thib ob winding tuaj yeem cuam tshuam rau hauv relay thiab teeb liab qhia rau kev tiv thaiv hluav taws xob ntawm AC fais fab. daim phiaj.
