抗器的方式可降低整套变频系统成本约10%,并减少占地空间,降低后期维护工作量。
汇川无扰切换技术的另一独到之处,在于可以控制第三方变频器的软启动。有些使用情况中,在早期配置高压变频器时并没有配置无扰切换,需要加装电抗柜等器件实现该功能,成本不菲。而汇川的无电抗器无扰切换可以通过软件控制第三方硬件,帮助各种类型的高压变频器实现功能升级。目前,已在高炉鼓风机等现场实现改造应用。
此次中标中,另一项受到关注的关键技术——机械式非对称旁路,是当高压变频器某个单元发生故障时,将故障单元从主回路中分离出去,保证变频系统正常运转,提高系统可靠性。汇川机械式旁路接触器线圈采用分布式供电,接触器的触点和线圈基本处于低压电位差,二者之间无需高压绝缘,保证安全;每个接触器的控制和检测部分通过每个功率单元完成,利用功率单元原有的光纤和主控系统进行通信,提高可靠性,降低成本。同时,变频器作为一个柔性变换的三相交流电源,以无中线的方式与电机连接,故而只要电机整个线电压为对称三相即可。三相线电压构成一个等边三角形。假如某些个单元发生了损坏,则可以采用漂移中性点的方法,改变PWM控制的相电压参考信号之间的夹角,达到输出线电压对称的目的。汇川的机械式非对称旁路技术运行经验丰富,目前至少有300
