Cov Tswv Yim Tseem Ceeb Cov txheej txheem suav tshwj xeeb yog raws li hauv qab no:
Raws li peb-theem fais fab kev suav mis P=1.732UIcosφ, qhov twg P yog lub zog, U yog voltage, kuv yog tam sim no, thiab cosφ yog fais fab tuag.
Fais fab thiab tam sim no xam : Raws li peb-theem fais fab kev suav mis P=1.732UIcosφ, qhov twg P yog lub zog, U yog voltage, kuv yog tam sim no, thiab cosφ yog lub hwj chim yam. Rau ib tug 120-kilowatt motor, nws tam sim no kuv yog hais txog 214 amperes.
Cable specification xaiv: Qhov kev nyab xeeb tam sim no txiav tawm ntawm 70 square tooj liab cores rau cov xov hlau qhib yog li ntawm 247 amperes, uas yog ntau dua li qhov ntsuas tam sim no, yog li nws tuaj yeem ua tau raws li qhov xav tau.
Hauv cov ntsiab lus, 120-kilowatt lub cev muaj zog yuav tsum tau nruab nrog tsawg kawg 70 square tooj liab tub ntxhais cables txhawm rau ua kom muaj kev nyab xeeb thiab ruaj khov. cov
