产品与解决方案

丹佛斯VLT 5驱动器推出50年了,是世界上第一个大规模生产的交流驱动器,也是Vacon成立25年来,最初的名称是Vaasa控制有限公司。

实际上,三相380伏输入的IGBT的耐压值是1200伏,往往要求工作在800伏以内,考虑到电压如果升高,都会有个惯性问题,也就是你马上让制动电阻工作了,母线电压也不会很快降低下来,所以很多变频器,都是设计在700伏左右就通过制动单元让制动电阻开始工作,让母线电压降低下来,避免往上继续冲。


结果,丹佛斯、wm工程和制冷型材公司提出的解决方案与改造前相比,能耗降低了15%左右。“丹佛斯设施取得的结果基本令人满意。他把对客户资源的需求结合起来,使成本效益成为正数。尤其是,我已经在丹佛斯设备公司工作了35年,并且已经了解了应用程序的性能。因此,我们的建议是肯定的,我们将执行完美的婚礼“,评论工程师马西奥莫雷诺,技术/行政主任西姆工程。
