Ua hauj lwm hauv paus ntsiab lus ntawm lub hwj chim transformer

Hauv kev hloov pauv hauv tsev, siab -voltage windings feem ntau txuas nrog Y- txuas. Cov kev sib txuas rau nruab nrab -voltage thiab low-voltage windings nyob ntawm qhov system tej yam kev mob. Cov xwm txheej hauv lub cev hais txog kev sib raug zoo ntawm qhov hluav taws xob phasors ntawm high-voltage transmission system thiab voltage phasors ntawm nruab nrab- lossis qis-voltage transmission system. Rau qis-voltage faib tshuab, txoj kev sib txuas tuaj yeem txiav txim siab raws li cov txheej txheem kev cai.

High-voltage windings feem ntau txuas nrog Y- kev sib txuas vim tias theem voltage tuaj yeem sib npaug li 57.7% ntawm kab hluav taws xob, tso cai rau qhov qis dua ib zaug.

Thaum lub 220/110/35kV transformer siv YN, yn0, d11 kev twb kev txuas, thiab ib tug 110/35/10kV transformer siv ib tug YN, yn0, d11 kev twb kev txuas, lub voltage phasors ntawm ob 35kV kis tau tus mob sib txawv los ntawm ib tug hluav taws xob lub kaum sab xis ntawm 30 degree.

Yog li ntawd, txoj kev sib txuas rau 60kV thiab 35kV windings yuav tsum tau ua tib zoo txiav txim siab, thiab txoj kev sib txuas yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm kev sib kis ntawm qhov hluav taws xob phasors. Txoj kev sib txuas rau 60kV thiab 35kV windings yog txiav txim siab raws li kev sib raug zoo ntawm cov hluav taws xob phasors. Tsis tas li ntawd, txawm tias qhov muaj peev xwm thiab qhov sib piv ntawm qhov hluav taws xob yog qhov tseeb, lub tshuab hloov pauv tsis tuaj yeem siv vim tias txoj kev sib txuas tsis raug, thiab lub tshuab hloov pauv tsis tuaj yeem txuas nrog lub zog xa hluav taws xob.
