Yuav Ua Li Cas Nrog Peb-theem Load Imbalance lossis Lub Caij Nplooj Ntoos Hlav Ntawm Fais Transformers

Los ntawm kev tshawb xyuas cov txiaj ntsig, nws tuaj yeem pom tias muaj ntau qhov tsis sib npaug ntawm peb-theem loads hauv cov khoom siv hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam nyob deb nroog uas feem ntau ntawm cov khoom siv fais fab yog ib-theem thiab cov load hloov tau zoo heev. Yog li ntawd, muaj ntau yam tsis sib npaug ntawm peb-theem loads nyob rau hauv tis transformers, uas ua rau nws tsis yooj yim sua rau peb-theem ua hauj lwm symmetrically thiab tsim zero sequence tam sim no. Ntawm qhov tod tes, qhov no ua rau kom poob ntawm lub transformer, thiab ntawm qhov tod tes, nws txo qhov muaj peev xwm ntawm transformer. Ob qho xwm txheej saum toj no yuav ua rau lub tshuab hluav taws xob overheat, cov roj rwb thaiv tsev rau lub hnub nyoog, thiab cov txheej txheem rwb thaiv tsev ntawm winding yuav txo qis, thaum kawg ua rau kev puas tsuaj ntawm cov khoom siv hluav taws xob. Cov kev ntsuas hauv qab no tuaj yeem ua tau:
① Tshawb xyuas qhov xwm txheej ntawm cov khoom xa tawm, suav nrog kev thauj khoom ntawm 24 teev hauv ib hnub thiab kev thauj khoom ntawm 4 lub caij hauv ib xyoos, nkag siab txog qhov kwv yees ntawm cov khoom thauj, thiab kho peb theem load kom ntau li ntau tau kom nws nyob ze. symmetrical kev ua haujlwm;
② Kho lub ncov thiab hav lub sij hawm ntawm kev siv hluav taws xob kom txo tau cov xwm txheej dhau los; Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum tau ua kom muaj peev xwm ntawm lub tshuab hloov pauv raws sijhawm kom tsis txhob muaj lub sijhawm ua haujlwm ntev ntawm lub tshuab hloov pauv.
