进线电抗器、输出电抗器、平波电抗器选择计算方法

1、进线电抗器、输出电抗器、平波电抗器选择计算方法1.进线电抗器1.1进线电抗器的额定电流ILN：对直流传动装置(6RA70)：TOC o 1-5 h zILN=0.82IdN(A)式中：IdN:传动装置额定整流电流，通常即为由其供电的电动机的额定电流(A)。dN对电压型变频器(6SE70)：【lnT.IIcn(A)式中：ICN:变频器额定输出电流，通常即为由其供电的电动机的额定电流(A)。对6SE70中的整流单元和整流/回馈单元：ILN=0-87Idc(A)式中：Idc:整流单元或整流/回馈单元额定输出电流(A)。1.2进线电抗器的电感值L：对直流传动装置(6RA70)和6SE70中的整流/回馈

2、单元按压降4%选择L：L=O.O4Uln/(30.5x2fILN)(H)式中：uln：进线电压的线电压有效值(V)f：电网频率(Hz)ILN:进线电抗器的额定电流(A)当f=50Hz时：L=73.51xUln/Iln(H)也可根据进线电抗器的进线电压Uln和额定电流ILN直接从下面的表1.1表1.4中选择进线电抗器(适用于f=50Hz)。对变频器(6SE70)和6SE70中的整流单元，按压降2%选择L：L=0.02xUln/(3.5x2fILN)(H)式中：uln：进线电压的线电压有效值(V)f：电网频率(Hz)ILN:进线电抗器的额定电流(A)当f=50Hz时：L=36.76xUln/Iln

3、(H)也可根据进线电抗器的进线电压Uln和额定电流ILN直接从下面的表1.5表1.8中选择进线电抗器(适用于f=50Hz)。表1.1进线电压：380(400)V额定压降：8.85V(4%)型号：HKSG2-0.8ILN(A)1822.42831.535.5405063L(H)156512581006894794704563447订货号K119-513K119-514K119-515K119-516K119-517K119-518K119-519K119-520718091100112125140160180397352310282282252201176157K119-521K119-522K
