Yog vim li cas Dyn11 yog siv nyob rau hauv Distribution Transformer
Distribution transformers ua lub luag haujlwm tseem ceeb hauv lub zog faib hluav taws xob ntawm lub teb chaws. Cov kev hloov pauv no yog lub luag haujlwm rau kev nqis qis ntawm cov hluav taws xob los ntawm cov kab hluav taws xob hluav taws xob mus rau cov hluav taws xob qis uas yuav siv tau los ntawm tsev neeg thiab cov lag luam. Ntawm qhov sib txawv transformer configurations, lub Dyn11 yog ib tug dav siv kev xaiv nyob rau hauv tis transformers. Cia peb nkag siab tias vim li cas Dyn11 thiaj li nrov hauv cov ntsiab lus no.
Dyn11 yog hais txog peb-theem transformer winding configuration nyob rau hauv uas cov thawj winding txuas ntawm theem 1 thiab 3, thaum lub thib ob winding txuas ntawm theem 2 thiab 4. Qhov nruab nrab point ntawm thawj winding yog grounded, thaum lub thib ob winding yog. tsis grounded. Qhov kev teeb tsa no tseem hu ua lub hnub qub zigzag lossis lub hnub qub hauv av.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv Dyn11 teeb tsa yog nws lub peev xwm los tswj cov khoom tsis sib xws hauv lub cev. Nyob rau hauv ib tug raug faib network, cov loads txuas nrog lub transformer feem ntau tsis sib npaug ntawm peb theem. Qhov no tsim qhov teeb meem tsis sib haum xeeb, uas tuaj yeem ua rau crosstalk thiab lwm yam kev cuam tshuam hauv lub cev. Lub Dyn11 configuration daws qhov teeb meem no los ntawm kev txo cov load unbalanced.
Lwm qhov zoo dua ntawm Dyn11 teeb tsa yog nws lub peev xwm los muab kev sib cais ntawm thawj thiab theem nrab winding. Lub hnub qub grounded kev twb kev txuas nyob rau hauv thawj sab ua hauj lwm pab raws li ib tug tiv thaiv av, tiv thaiv tej yam txhaum nyob rau hauv lub thib ob sab los ntawm adversely cuam tshuam rau thawj sab.
Tsis tas li ntawd, Dyn11 configuration tuaj yeem txo qhov xau inductance ntawm transformer, uas tuaj yeem txhim kho kev ua haujlwm ntawm lub cev. Lub zigzag configuration ntawm thawj winding ua rau ib tug qis to inductance tshaj lwm configurations, xws li lub Delta-Delta los yog YY.
Hauv cov ntsiab lus, Dyn11 configuration yog ib qho kev xaiv zoo tshaj plaws rau kev faib cov khoom siv hluav taws xob vim tias nws lub peev xwm los tswj cov khoom tsis sib npaug, muab kev sib cais ntawm thawj thiab theem nrab winding, txo cov xau inductance, thiab txhim kho kev ua haujlwm. Cov txiaj ntsig no ua rau Dyn11 qhov kev xaiv nrov rau cov tuam txhab faib hluav taws xob thoob ntiaj teb.
