Fais fab mov txoj kev ntawm lub hwj chim transformer

Lub 10kV siab-voltage power grid ua haujlwm siv peb-theem, peb-wire, ungrounded neutral system.

Feem ntau cov neeg siv hloov pauv siv Yyn0 kev sib txuas teeb tsa nrog lub hauv paus ncaj qha nruab nrab, ua rau peb -theem plaub-hlau lossis tsib- xaim hluav taws xob, xws li TN-S system.

Peb-theem transformers thiab transformer banks tuaj yeem txuas rau hauv lub hnub qub, delta, lossis zigzag configurations, sawv cev los ntawm Y, D, thiab Z cov cim ntawm lub siab -voltage sab thiab y, d, thiab z cim nyob rau qis- voltage sab. Thaum muab qhov nruab nrab nruab nrab, siab -voltage yog sawv cev los ntawm YN thiab ZN cim, thiab qis-voltage los ntawm yn thiab zn cim. Muaj 12 pab pawg sib txuas tau nyob ntawm qhov sib txawv ntawm kev sib txuas ntawm peb -theem windings. Txawm li cas los xij, kom yooj yim ntawm kev tsim thiab siv, kuv lub teb chaws Ameslikas tau teev tsib pawg kev sib txuas: Y, Yn0 (Y / Y0-12); Y, Yn (Y/Y-12); YN, Yn (Y0/Y-12); Y, d11 (Y/Δ-11); YN, d11 (Y0/Δ-11).
