进出线电抗器的选择

1、关于变频器进出线电抗器的选择随着电力电子技术的迅速开展,从20世纪90年代以来,交流变频调速已成为电气传动的主流,其应用范围日益广泛.由于变频器被使用在各种不同的电气环境,不采取恰当的保护举措,就会影响变频器运行的稳定性和可靠性.实践证实,适中选配电抗器与变频器配套使用,可以有效地预防因操作交流进线开关而产生的过电压和浪涌电流对它的冲击,同时亦可以减少变频器产生的谐波对电网的污染,并可提升变频器的功率因数.因此探讨与变频器配套用的进出线电抗器的选择方法是十分必要的.一、关于变频器进线线电抗器的选择问题1,额定交流电流的选择额定交流电流是从发热方面设计电抗器的长期工作电流,同时应该考虑足够的高次

2、谐波分量.即输入电抗器实际流过的电流是变频器的输入电流.2,阻抗电压降阻抗电压降是指50HZ时,对应实际额定电流时电抗器线圈两端的实际电压降.通常选择阻抗电压降在4V8V左右.3,电感量的选择电抗器的额定电感量也是一个重要的参数！假设电感量选择不适宜,会直接影响额定电流下的阻抗电压降的变化,从而引起故障.而电感量的大小取决于电抗器铁芯的截面积和线圈的匝数与气隙的调整.选择了额定交流电流与阻抗电压降也就确定了电感量.二、关于变频器出线电抗器的选择问题1 ,额定交流电流的选择额定交流电流是从发热方面设计电抗器的长期工作电流,同时应该考虑足够的高次谐波分量.即输出电抗器实际流过的电流是变频器电机负载

3、的输出电流.2 ,阻抗电压降阻抗电压降是指50HZ时,对应实际额定电流时电抗器线圈两端的实际电压降.通常选择阻抗电压降在2V8V左右.3 ,电感量的选择电抗器的额定电感量也是一个重要的参数！假设电感量选择不适宜,会直接影响额定电流下的电压降的变化,从而引起故障.而电感量的大小取决于电抗器铁芯的截面积和线圈的匝数与气隙的调整.输出电抗器电感量的选择主要是根据在额定频率范围内的电缆长度来确定,然后再根据电动机的实际额定电流来选择相应电感量要求下的铁芯截面积和导线截面积,才能确定实际电压降.4,对应额定电流的电感量与电缆长度:电缆长度额定输出电流电感量300米600米100A92仙H100A184仙

5、储能的特点,理想电抗器是不消耗电能的.电抗器就其磁路结构而言,有空气式电抗器和带间隙的铁心电抗器两种.并联电抗器是指并联连接在电力系统上的电抗器,它主要用来补偿电容电流,抑制轻载时端电压的升高.通常中小容量的并联电抗器采用铁心式结构,而大容量的并联电抗器较多地采用空心式结构.消弧线圈是用来补偿中性点绝缘系统发生对地故障时产生的容性电流的单相电抗器.消弧线圈的磁路一般采用带多个气隙的铁心.在系统发生对地故障时,它的线圈中流过的补偿电流不大,因而磁路一般不会饱和,电感参数保持线性.由于采用铁心式结构,其体积也可做得较小.限流电抗器是在系统发生故障时用来限制电流的电抗器,它包括串联限流电抗器、启动电

6、抗器等.对于中、小容量一般采用带间隙的铁心式结构,对于大容量一般采用空心式结构.进出线电抗器与变频器的进、出端相串联,作为变频器的进线电抗器和出线电抗器.变频器在工作时将产生较大的谐波,加装进线电抗器,将大幅度提升变频器及用电设备的使用寿命,谐波干扰严重时,会导致某些设备不能正常运行,加装进线电抗器后将大幅度降低各谐波的含量,提升电网的功率因数,保证变频器及其它用电设备的平安运行,保证其它用电设备不受谐波干扰影响,而且该电抗器在负载合闸瞬间能够有效地抑制回路涌流,保护回路中的变频器装置及其它元器件免受过电流冲击；加装出线电抗器可以钝化变频器输出电压开关频率的陡度,减少逆变器中的功率元件的扰动和

7、冲击,另外可降低由于电缆电容引起的电机绕组过电压,可延长变频器到电机之间的距离,提升电机的使用寿命.进、出线电抗器用于与变频器的进、出端相串联,作为变频器的进线电抗器和出线电抗器.变频器在工作时将产生较大的谐波,如果不加装进线电抗器,将大幅度降低变频器及用电设备的使用寿命,谐波干扰严重时,会导致某些设备不能正常运行,加装进线电抗器后将大幅度降低各谐波的含量,提升电网的功率因数,保证变频器及其它用电设备的平安运行,保证其它用电设备不受谐波干扰影响,而且该电抗器在负载合闸瞬间能够有效地抑制回路涌流,保护回路中的变频器装置及其它元器件免受过电流冲击；加装出线电抗器可以钝化变频器输出电压开关频率的陡度

8、,减少逆变器中的功率元件的扰动和冲击,另外可降低由于电缆电容引起的电机绕组过电压,可延长变频器到电机之间的距离,提升电机的使用寿命.直流平波电抗器串联在直流电路中能减少电流脉动,提升网侧的功率因数,改善网侧的波形,降低谐波含量,提升设备的可靠性.磁控可调电抗器是借助于磁饱和现象,利用直流激磁作用改变铁芯磁状态工作点及磁特性,从而改变交流绕组的电抗值的.通过外激磁电压的调节,可均匀、平滑、稳定的改变电抗值,满足不同使用目的.当该电抗器并联在电路中,它是一个可调的感性负载,可用于负载试验装置中及无功补偿功率因数自动调节系统中.当该电抗器串联在电路中,它起到调压和降压作用,可用于交流电动机限流软起动
