在我国的各港口,西门子变频器的应用程度非常高,这类变频器具有集成化程度高、功率范围广泛等特点。以上海港为例,负责装卸集装箱的岸桥有相当一部分采用西门子变频器。不过长时间的使用对于变频器来说,它的维护成本也是水涨船高。一旦停机,其经济损失难以估量。因此,如何迅速准确地查找出故 In our country’s ports, Siemens inverter application is very high, this type of inverter with a high degree of integration, a wide range of power characteristics. For example, for the above port, a considerable part of the shore bridge responsible for loading and unloading containers adopts Siemens frequency converter. However, the long-term use of the inverter, its maintenance costs are soaring. Once shut down, its economic loss is hard to measure. Therefore, how to quickly and accurately find out why
