Thaum nws los rau kev sib txuas 3-theem fais fab kev siv, ob txoj kev sib xws yog lub hnub qub (lossis Wye) kev sib txuas thiab kev sib txuas ntawm Delta. Ob txoj kev muaj lawv tus kheej qhov zoo thiab cov ntawv thov, yog li nws yog ib qho tseem ceeb kom nkag siab txog qhov sib txawv ntawm lawv. Ib qho ntawm cov qauv hluav taws xob muaj hluav taws xob engineering yog kev nkag siab tias 3-theem system tau txuas nrog: lub hnub qub (y) lossis delta (Δ). Ob leeg puav leej siv dav, tab sis nyob rau ntau txoj kev.
Lub Hnub Qub (Y) Kev Txuas
{{0- Tsis Muaj Muaj Muaj Peev Xwm Muaj peev xwm muab tau ob qho tib si 3 -}} theem loads.
{{0- kab voltage= √} √has √ase voltage (qib siab voltage).
{{0-} nquag siv rau ntev- huab cua nrug ua rau nws txo cov kev xav tau.
{{0 {} Pib tam sim no yog qis → Zoo rau kev pib hnyav lub motors hauv lub hnub qub ua ntej hloov mus rau Delta.
Delta (Δ) kev sib txuas
{{0 {}} Tsis muaj qhov nruab nrab (tsuas yog 3 xaim).
{{0 {}} kab voltage =}}}}}} }ase voltage (ntws rov qab).
-}}}}} muaj siab dua pib pib → feem ntau siv rau kev faib tawm thiab khiav ntawm cov motors hnyav.
- Ntau dua Robust, tuaj yeem ua kom khiav txawm tias ib qib poob qis (qhib delta).
Txoj cai ntawm tus ntiv tes xoo:
Lub hnub qub → Zoo tshaj plaws rau kis & sib xyaw (3 {{{}}}} theem) thauj khoom.
Delta → Qhov zoo tshaj plaws rau kev faib tawm & khiav hnyav 3-theem machine.
Ib qho kev sib txuas hnub qub feem ntau yog siv nyob rau hauv cov kab ke uas lub nra muaj tusyees faib ntawm peb ntu. Qhov kev teeb tsa no yog qhov zoo tagnrho rau cov kab ke nrog tov nrog kev sib xyaw nrog cov khoom siv hluav taws xob. Ntawm qhov tod tes, ib qho kev sib txuas hauv qab yog nyiam rau cov tshuab nrog feem ntau high- fais fab ntim lossis rau cov ntawv siv voltage ntau dua.
