4kw电机的额定电流为多大?怎么选配三相电表?
(3 8 0 TDRZ)4 KR电动机的电动机是电流:1 5 5 a。从2 0(8 0)a。
በሶስት-ደረጃደረጃኃይልስሌት(CASSA)(cos÷(÷3 ucosa)ነው。
. Apply-P = √√√osa, the general power of the South-level district of the three-level districts. Three-level circuits is equal to symmetry three-level circuits and asymmight. Three-level circuits can be divided. Power可以将平均功率p = pa + pc = 3 pcos = 3 pcos = 3 pcos = 3 pcos = 3 pcos = 3 pcos = 3 pcos = 3 pcos = 3 pcos = 3 pcos = 3 pcos = 3 pcos = 3 pcos = 3 p = 3 p。
等于平均电压的平均体积。
