Distribution Transformer Winding kev sib txuas
Distribution transformers yog cov khoom tseem ceeb hauv lub zog hluav taws xob, muab kev hloov pauv hluav taws xob thiab xa mus rau cov neeg siv kawg. Cov kev sib txuas winding, uas yog ib feem tseem ceeb ntawm lub transformer, ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov sib piv ntawm qhov voltage thiab theem kev sib raug zoo ntawm thawj thiab theem nrab windings.
Kev lig kev cai, cov transformers faib ua ob hom: ib-theem thiab peb-theem transformers. Ib-theem transformers muaj ob windings, thawj thiab theem nrab, thaum peb-theem transformers muaj peb windings- ib tug thawj thiab ob theem nrab (delta los yog wye). Cov kev sib txuas winding txiav txim siab li cas cov windings txuas nrog rau ib daim ntawv thov tshwj xeeb.
Muaj ob hom kev sib txuas ntawm winding rau kev faib cov transformers: delta (Δ) thiab wye (Y). Kev sib txuas delta yog nrov siv nyob rau hauv cov khoom siv hluav taws xob tsawg, thaum wye kev twb kev txuas yog siv nyob rau hauv high voltage kis tau tus mob thiab tis systems.
Hauv kev sib txuas ntawm delta, cov thawj thiab theem nrab windings tau txuas nrog txoj hauv kev uas qhov kawg ntawm ib qho winding txuas nrog rau qhov pib ntawm qhov txuas ntxiv winding, tsim ib lub voj kaw hauv cov duab peb sab. Qhov kev sib txuas no muaj ntau qhov zoo, suav nrog kev ua haujlwm siab, tus nqi qis, thiab kev tswj hwm qhov hluav taws xob zoo dua. Txawm li cas los xij, qhov tsis zoo ntawm qhov kev sib txuas no yog tias nws tsis muab qhov nruab nrab ntawm qhov nruab nrab, uas tuaj yeem ua rau tsis muaj qhov sib npaug ntawm cov hluav taws xob thiab cov khoom siv tam sim no.
Wye kev twb kev txuas, ntawm qhov tod tes, txuas lub hauv paus thiab theem nrab windings mus rau ib qho chaw hu ua qhov nruab nrab. Qhov nruab nrab feem ntau yog hauv av rau kev nyab xeeb. Kev sib txuas wye muaj ntau qhov zoo ib yam, suav nrog kev muab qhov nruab nrab ntawm qhov nruab nrab, tso cai rau kev sib txuas tsis sib luag, thiab txo qhov impedance ntawm transformer winding thiab hauv av. Txawm li cas los xij, qhov tsis zoo ntawm qhov kev sib txuas no yog tias nws ua rau qis qis dua thiab tus nqi siab dua vim qhov ntxiv winding.
Hauv kev xaus, kev xaiv ntawm kev sib txuas winding nyob ntawm ntau yam xws li daim ntawv thov, hom thauj khoom, thiab qhov system voltage. Txhua qhov kev sib txuas muaj nws qhov zoo thiab qhov tsis zoo, thiab qhov kev xaiv zoo yog nyob ntawm cov kev cai tshwj xeeb ntawm lub zog hluav taws xob. Distribution transformer winding kev sib txuas ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm tag nrho thiab kev ntseeg siab ntawm lub zog hluav taws xob.
