Vector Group Of Distribution Transformer
Lub tshuab hluav taws xob faib hluav taws xob yog ib qho khoom siv hluav taws xob uas siv los hloov hluav taws xob hluav taws xob los ntawm qhov chaw faib hluav taws xob mus rau lwm qhov kev faib khoom nruab nrab. Nws yog tsim los hloov cov hluav taws xob hluav taws xob los ntawm qhov hluav taws xob ntau dua mus rau qib qis dua uas siv tau los ntawm tsev neeg thiab cov lag luam. Ib qho tseem ceeb ntawm kev faib khoom transformer yog pawg vector, uas yog cov cai uas qhia txog theem hloov ntawm cov thawj thiab theem nrab windings.
Pawg vector ntawm lub transformer faib yog qhia los ntawm ib tug series ntawm cov tsiaj ntawv thiab cov zauv, nrog rau txhua tsab ntawv qhia lub kaum sab xis ntawm lub windings, thiab txhua tus lej qhia txog kev sib txuas ntawm cov windings. Thawj tsab ntawv qhia txog qhov siab voltage (HV) winding configuration, thaum tsab ntawv thib ob qhia txog qhov qis voltage (LV) winding configuration. Tsab ntawv thib peb qhia txog theem hloov ntawm lub hauv paus thiab theem nrab windings.
Piv txwv li, pawg vector Yyn{{0}} qhia txog lub transformer nrog high voltage winding txuas nyob rau hauv lub hnub qub configuration, tsis tshua muaj voltage winding txuas nyob rau hauv lub hnub qub configuration, thiab ib theem hloov ntawm 0 degrees ntawm thawj. thiab lwm yam windings. Ib yam li ntawd, pawg vector Dyn11 qhia txog kev hloov pauv nrog delta-txuas nrog high voltage winding, lub hnub qub txuas nrog qis voltage winding, thiab theem hloov ntawm 11 degrees.
Kev xaiv ntawm pawg vector yog qhov tseem ceeb vim tias nws cuam tshuam rau txoj hauv kev uas lub tshuab hloov pauv tau ua haujlwm thiab tiv thaiv, nrog rau txoj hauv kev uas nws txuas nrog lub network. Qee pawg vector muaj ntau dua li lwm tus, nyob ntawm daim ntawv thov tshwj xeeb thiab cov kev xav tau ntawm lub network.
Ntxiv rau pawg vector, lwm yam tseem ceeb uas yuav tsum tau xav txog thaum xaiv lub tshuab hluav taws xob faib khoom suav nrog lub zog ntsuas, qhov ua tau zoo, qib rwb thaiv tsev, thiab impedance. Cov kev ntsuas no txiav txim siab qhov ua tau zoo, kev ntseeg siab, thiab kev nyab xeeb ntawm lub tshuab hloov pauv, thiab tseem ceeb heev kom ntseeg tau tias lub network ua haujlwm tau zoo thiab ua tau zoo.
Zuag qhia tag nrho, pawg vector yog ib qho tseem ceeb ntawm kev faib khoom transformer, raws li nws txiav txim siab hloov theem ntawm thawj thiab theem nrab windings. Los ntawm kev xaiv pawg vector tsim nyog, cov neeg ua haujlwm hauv lub network tuaj yeem ua kom ntseeg tau tias lub tshuab hloov pauv tau nruab thiab ua haujlwm raug, thiab nws xa cov hluav taws xob muaj zog thiab muaj kev nyab xeeb rau tsev neeg thiab kev lag luam.
