Lub hom phiaj thiab cov qauv ntawm Kev Ntsuas Winding Resistance
Transformer winding tsis kam yog qhov tseem ceeb ntawm qhov ntsuas hauv kev lag luam hluav taws xob hluav taws xob. Transformer winding kuj yog ib qho ntawm cov ntsiab lus tseem ceeb uas txiav txim siab qhov ua tau zoo ntawm transformer. Nws yog ib qho tseem ceeb los ntsuas lub winding kuj precisely los ua qhov zoo tagnrho kev ua hauj lwm ntawm lub transformer.
Yuav kom paub qhov transformer winding kuj yog qhov tseem ceeb. Tus nqi yog xav tau rau kev suav ntxiv
thiab ua haujlwm ntau yam xws li:
1. Tshawb xyuas cov kev sib txuas hauv winding.
2. Load poob xam (kev ntsuas luv luv)
3. Txoj kev indirect tsim lubwinding kub thiab kub nce nyob rau hauv ibwinding.
4. Txheeb xyuas qhov hluav taws xob txuas ntxiv nyob rau hauv ib qho winding
Txheem ntsuas winding kuj
IEC 60076-1 Clause 10.2: "Kev ntsuas ntawm winding resistance"
IEEEC 57.12.90 Clause 5: "Kev ntsuas ntsuas"
VDE0532-76-1Table 3.1.1: Associated Standards
Nws yog ib qho tsim nyog yuav tsum nkag siab tias qhov resistivity ntawm tus neeg xyuas pib ntaub muaj zog nyob ntawm qhov kub thiab txias. Qhov kev lees paub zoo yog nrog qhov kub thiab txias, cov khoom siv lub zog kuj nce ntxiv.A tus nqi ntawm kev tiv thaiv yam tsis muaj qhov kub thiab txias tsis muaj txiaj ntsig, txwv tsis pub qhov kev tiv thaiv yuav raug txiav txim siab ntawm chav tsev kub. Txoj kev tsis ncaj ncees ntawm kev tsim kom muaj qhov kub thiab txias tuaj yeem ua tiav los ntawm kev rov ntsuas qhov ntsuas ntawm qhov ntsuas kub ntxiv
