Kev sib txuas ntawm cov xa khoom xa tuaj
Kev faib khoom xa tuaj feem ntau txuas rau hauv lub hnub qub (Y) lossis Delta (Δ) kev sib txuas.
Ntawm no yog cov lus qhia luv luv rau lub hnub qub thiab Delta Connections:
Lub hnub qub (y) kev sib txuas:
Feem ntau hais lus, kev sib txuas hnub qub yog siv rau thawj sab (sab kev kub siab).
Qhov kev sib txuas no muab ib qho chaw nruab nrab thiab tso cai rau kev sib txuas ntawm kab nruab nrab. Nov yog qhov sib txawv tseem ceeb los ntawm kev sib txuas ntawm Delta.
Nws pab kom txo cov theem voltage thiab tswj cov khoom siv tsis muaj zog.
Raws (Δ) kev sib txuas:
Qhov kev sib txuas hauv Delta feem ntau yog siv nyob rau sab nraud (sab voltage qis).
Qhov kev sib txuas no txhawb nqa cov thauj khoom siab dua thiab muab cov kev cai voltage zoo dua.
Nws tuaj yeem ua tau cov khoom tsis muaj zog uas muaj zog dua thiab tsis tas yuav nruab nrab.
Cov pab pawg sawv cev:
Piv txwv li, yy {{0, ΔY1, thiab lwm yam sawv cev ntawm sab high-voltage sab thiab tsawg-voltage sab ntawm cov transformer.
Thawj tsab ntawv sawv cev rau txoj kev sib txuas ntawm lub siab-voltage sab (Y lossis δ).
Tsab ntawv thib ob sawv cev rau txoj kev sib txuas ntawm qhov qis-voltage sab (Y lossis δ).
Cov naj npawb hauv qab no sawv cev rau kev hloov chaw ntawm theem kaum. ({0: sawv cev
Qhov kev xaiv ntawm ob txoj kev sib txuas yog nyob ntawm cov ntaub ntawv tshwj xeeb ntawm cov cuab yeej siv fais fab, voltage theem thiab load cov yam ntxwv.Yawei TransformerYuav muab cov kev pab tswvyim pab koj.
