Transformers yog cov khoom tseem ceeb hauv cov tshuab hluav taws xob hluav taws xob, ua kom muaj hluav taws xob hloov pauv thiab kev faib tawm. Ntawm cov kev teeb tsa ntau yam siv hauv transformers, Delta (Δ) thiab Wye (Y) configurations yog feem ntau.
Delta Configuration (Δ)
Yam ntxwv
Hauv Delta configuration, peb qhov kev sib txuas ua ke tseem ceeb ua rau lub voj kaw zoo ib yam li daim duab peb sab. Txhua qhov winding yog txuas rau qhov kawg-rau-kawg, tsim peb cov nodes qhov twg qhov voltage hla txhua qhov winding yog sib npaug rau cov kab hluav taws xob.
Qhov zoo
Lub zog muaj peev xwm ntau dua: Delta transformers tuaj yeem ua haujlwm ntau dua, ua rau lawv tsim nyog rau kev lag luam.
Phase Balance: Delta kev sib txuas muab cov theem zoo sib npaug, uas yog qhov tseem ceeb rau kev txo qis kev sib raug zoo hauv cov tshuab hluav taws xob.
Tsis muaj nruab nrab: Delta configurations tsis xav tau ib tug nruab nrab xaim, simplifying lub thaiv system thiab txo cov nqi khoom.
Daim ntawv thov
Feem ntau siv nyob rau hauv kev siv lub cev muaj zog vim lawv muaj peev xwm los tuav siab pib tam sim no.
Feem ntau siv hauv cov tsev lag luam loj rau kev teeb pom kev zoo thiab hluav taws xob faib khoom.
Feem ntau ua hauj lwm nyob rau hauv kauj ruam-down transformers, qhov twg high voltage yuav tsum tau hloov mus rau qis voltage theem.
Wye Configuration (Y)
Yam ntxwv
Hauv Wye configuration, ib qho kawg ntawm txhua qhov winding txuas nrog rau ib qho kev taw qhia (qhov nruab nrab), tsim cov duab zoo li tsab ntawv "Y." Qhov voltage thoob plaws txhua qhov winding yog sib npaug rau cov kab hluav taws xob faib los ntawm lub hauv paus square ntawm peb.
Qhov zoo
Nruab Nrab Point: Wye configuration muab ib qho nruab nrab taw tes, tso cai rau kev siv ntawm ib-theem loads tsis cuam tshuam rau peb-theem tshuav nyiaj li cas.
Lower Phase Voltage: Cov kab-rau-nruab nrab voltage yog qis dua cov kab-rau-kab voltage, uas tuaj yeem muaj txiaj ntsig zoo rau qee yam kev siv.
Kev Tiv Thaiv Kev Tiv Thaiv Kev Ua Phem hauv av: Lub ntsiab lus nruab nrab tuaj yeem ua rau hauv av, txhim kho kev nyab xeeb thiab muab txoj hauv kev rau kev txhaum tam sim no.
Daim ntawv thov
Dav siv nyob rau hauv vaj tse thiab kev lag luam hluav taws xob faib tshuab.
Haum rau kev muab fais fab rau ib-theem loads hauv peb-theem systems.
Feem ntau siv nyob rau hauv cov kauj ruam-up transformers, qhov uas qis voltage yog hloov mus rau siab dua voltage rau kis tau tus mob.
