Distribution Transformer Vector Group
Distribution transformers yog cov cuab yeej siv los tswj cov qib voltage hauv cov tshuab hluav taws xob. Ib qho tseem ceeb ntawm kev faib cov transformers yog lawv pawg vector, uas txiav txim siab theem sib txawv ntawm lawv cov thawj thiab theem nrab voltages. Qhov no yog qhov tseem ceeb rau kev ua kom muaj kev ua haujlwm raug ntawm lub tshuab hluav taws xob thiab zam kev puas tsuaj rau cov khoom siv.
Pawg vector yog ib txoj cai uas qhia txog kev sib raug zoo ntawm thawj thiab theem nrab winding voltages nyob rau hauv ib tug transformer. Nws muaj kev sib xyaw ua ke ntawm cov tsiaj ntawv thiab cov lej uas piav qhia txog theem hloov ntawm cov windings. Txhua tsab ntawv sawv cev rau tus txheeb ze txoj hauj lwm ntawm lub kaum sab xis ntawm lub hauv paus thiab theem nrab windings, thaum tus naj npawb qhia txog qhov feem ntawm qhov hluav taws xob hloov ntawm lub hauv paus mus rau theem nrab.
Muaj ntau ntau pawg vector sib txawv uas feem ntau siv rau kev faib khoom transformers. Cov no suav nrog Yyn{{0}}, Dd0, Dyn5, thiab Yzn11, thiab lwm yam. Kev xaiv ntawm pawg vector nyob ntawm qhov tshwj xeeb yuav tsum tau ntawm cov hluav taws xob, xws li qib voltage, load yam ntxwv, thiab hom khoom siv.
Piv txwv li, Yyn {{0}} yog ib pab pawg vector rau me me thiab nruab nrab-qhov loj me tis transformers, raws li nws muab ib tug balanced voltage tso zis nrog ib tug xoom degree theem hloov. Qhov no ua rau nws tsim nyog rau ntau hom kev thauj khoom thiab khoom siv. Dd0, ntawm qhov tod tes, yog ib pawg vector uas tau tsim tshwj xeeb rau kev siv hluav taws xob tsawg, thiab feem ntau siv rau hauv chaw tsim khoom.
Dyn5 yog ib pawg vector uas muab kev teeb tsa delta rau ntawm thawj sab thiab lub hnub qub teeb tsa ntawm sab thib ob. Qhov no ua rau nws zoo haum rau cov ntawv siv hluav taws xob siab, vim nws tso cai rau kev sib kis tau zoo ntawm lub zog dhau mus ntev. Yzn11 yog lwm pawg vector nrov uas feem ntau siv hauv lub tshuab hluav taws xob nrog ntau lub tshuab hloov pauv, vim nws muab cov qib siab ntawm kev hloov pauv thiab tso cai rau kev txhim kho yooj yim ntawm lub kaw lus.
Nws yog ib qho tseem ceeb uas yuav tsum xaiv pawg vector kom raug rau lub tshuab hluav taws xob faib hluav taws xob txhawm rau txhawm rau ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm cov hluav taws xob. Kev hloov pauv tsis raug cai tuaj yeem ua rau muaj qhov tsis sib xws, lub zog poob, thiab cov khoom puas tsuaj, uas tuaj yeem raug nqi kho thiab cuam tshuam kev ua haujlwm ntawm cov hluav taws xob network. Kev sab laj nrog tus kws tshaj lij hluav taws xob tsim nyog tau pom zoo los xyuas kom meej qhov kev xaiv raug thiab teeb tsa ntawm cov khoom xa tawm.
