Q: Dab tsi yog qhov ntsuas qhov sib piv, thiab cov teeb meem dab tsi tuaj yeem nthuav tawm?
A: Kev ntsuas qhov ntsuas qhov sib npaug (TTR) ntsuas qhov sib piv ntawm cov lej hloov pauv hauv qhov siab -voltage winding mus rau qis-voltage winding. Rau kev noj qab haus huv transformer, qhov sib piv no yuav tsum phim lub npe phaj voltage piv li ± 0.5%.
Vim li cas nws tseem ceeb:
• Tshawb xyuas luv luv-circuited lem - feem ntau thaum ntxov-stage winding txhaum.
• txheeb xyuas tus kais tsis raug - hloov chaw lossis kais - teeb meem kev sib cuag.
• Txheeb xyuas qhov tseeb winding txuas tom qab rov- sib dhos lossis kho.
Cov txiaj ntsig zoo li cas qhia tias:
|
Qhov xwm txheej |
Ua Tau |
|
Ratio siab ntawm ib theem |
Luv-circuited tig rau HV winding |
|
Ratio qis ntawm ib theem |
Luv luv -circuited ntawm LV winding |
|
Tag nrho peb theem tawm los ntawm tib tus nqi |
Tsis ncaj kais txoj hauj lwm los yog lub npe phaj yuam kev |
|
Qhov sib piv sib txawv nrog txoj haujlwm kais |
Coj mus rhaub -hloov mechanism txhaum |
Tus Qauv rau qhov kev sib tw tig yog dab tsi?
Raws li IEC 60076-1 thiab IEEE C57.12.90, qhov ntsuas qhov sib txawv ntawm qhov ntsuas yuav tsum tsis pub tshaj 0.5% los ntawm kev suav tus nqi rau fais fab transformers.
