Fais fab thiab faib Transformer muaj peev xwm xam cov qauv
1. Xam lub zog siab tshaj plaws ntawm txhua theem ntawm kev thauj khoom
Ntxiv lub zog thauj khoom ntawm txhua theem ntawm A-theem, B-theem thiab C-theem ntawm nws tus kheej. Piv txwv li, tag nrho lub zog ntawm A-theem load yog 10KW, tag nrho lub zog ntawm B-theem load yog 9KW, thiab tag nrho lub zog ntawm C-theem load yog 11KW, thiab tus nqi siab tshaj plaws yog 11KW. (Faj seeb: Lub hwj chim ntawm txhua lub cuab yeej ib zaug yog xam raws li tus nqi siab tshaj plaws ntawm daim ntawv teev npe, thiab peb theem ntawm cov cuab yeej hluav taws xob tau muab faib los ntawm 3, uas yog sib npaug rau lub zog ntawm txhua theem ntawm cov cuab yeej no.)
Piv txwv li: C-theem load tag nrho lub zog=(lub computer 300WX10 units) plus (cua txias 2KWX4 units)=11KW
2. Xam peb lub zog tag nrho
11KWX3-theem=33KW (transformer peb-theem tag nrho lub zog)
Peb-theem tag nrho lub zog /0.8 yog kauj ruam tseem ceeb tshaj plaws. Tam sim no, ntau dua 90 feem pua ntawm cov transformers ntawm lub khw muaj lub zog ntawm 0.8, yog li nws yuav tsum tau muab faib los ntawm lub zog ntawm 0.8.
33KW / 0 8=41.25KW (tag nrho transformer fais fab)
Tag nrho lub zog ntawm transformer yog /0.85. Raws li Daim Ntawv Qhia Txog Kev Tsim Hluav Taws Xob Hluav Taws Xob, lub peev xwm ntawm lub tshuab hluav taws xob yuav tsum raug xaiv raws li kev suav load. Rau ib qho kev hloov pauv uas muab lub zog nrog lub zog ruaj khov, tus nqi thauj khoom feem ntau yog li 85 feem pua.
41.25KW/0.85=48.529KW (transformer fais fab yuav tsum tau yuav), ces koj tuaj yeem xaiv 50KVA transformer thaum yuav khoom.
