Fais fab transformersFeem ntau siv Delta-Star (Δ-Y) kev sib txuas vim muaj ntau yam zoo:
1. Voltage thiab tam sim no tuav: Delta kev twb kev txuas ntawm lub hauv paus (high-voltage) sab tso cai rau lub transformer los tuav ntau dua voltages nrog qis tam sim no piv rau lub hnub qub kev twb kev txuas. Qhov no yog qhov zoo vim nws txo qhov tam sim no ntws los ntawm cov thawj windings, yog li txo qhov kev poob qis thiab ua rau covtransformersiv tau ntau dua.
2. Phase ua haujlwm: Delta configuration qhia txog 30 degree theem hloov ntawm thawj thiab theem nrab voltages. Qhov kev hloov pauv no tuaj yeem muaj txiaj ntsig zoo hauv qee cov ntawv thov uas nws pab kom sib npaug ntawm cov khoom hauv peb-theem thiab txo cov kev sib raug zoo tam sim no.
3. Load Flexibility: Lub hnub qub kev twb kev txuas nyob rau theem nrab (tsawg-voltage) sab muab ib qho nruab nrab taw tes uas tso cai rau kev sib txuas ntawm ib-theem loads ntawm txhua theem thiab nruab nrab. Qhov no yog tshwj xeeb tshaj yog pab tau nyob rau hauv kev faib khoom uas ib-theem loads muaj ntau.
4. Fault Tolerance: Delta configurations inherently ntau kam rau faults piv rau lub hnub qub configurations. Hauv Delta-Star transformer, yog tias ib theem hauv delta thawj winding yog grounded, lub transformer tuaj yeem ua haujlwm txuas ntxiv nrog rau ob theem ntxiv, txawm tias muaj peev xwm txo qis.
5. Nqi Efficiency: Delta-Star configuration feem ntau ua rau cov nqi txuag vim txo cov khoom siv. Delta windings xav tau cov khoom siv hluav taws xob tsawg dua rau tib qhov ntsuas hluav taws xob piv rau lub hnub qub windings, ua rau txo qis tooj liab thiab txo cov khoom siv tag nrho.
6. Lub cev muaj zog pib: Delta-Star kev twb kev txuas yog zoo haum rau muab hwj chim rau motors thiab lwm yam inductive loads. Lub delta thawj winding muab siab dua pib torque rau motors vim qhov qis impedance thiab siab dua tam sim no muaj peev xwm.
Hauv cov ntsiab lus,qhov kev sib txuas ntawm Delta-Star yog xaiv raufaib transformersFeem ntau los txhim kho kev ua tau zoo, txo qhov poob, tswj cov hluav taws xob ntau dua kom zoo, thiab ua kom haum raws li cov yam ntxwv ntawm cov khoom siv hauv kev faib khoom, suav nrog kev xav tau ntawm ob theem thiab ib-theem loads. Cov yam tseem ceeb no koom ua ke rau nws txoj kev siv dav hauv hluav taws xob faib hluav taws xob thoob ntiaj teb.
