变频调速渣浆泵的电压选择

Voltage Selection for Slurry Pump complete with VSD

对于特定功率段的变频器,既可以采用低压(380 V)也可以采用中压(10 kV),如何选择应进行技术经济比较。本文以实际工程为例,通过比较两种电压的初始投资费用和运行费用,根据综合费用最优的原则选择变频器电压。

For frequency converters in a specific power segment,either low voltage(380 V)or medium voltage(10 kV)can be used.As to how to make the selection,a techno-economic comparison shall be conducted.In this paper,actual project is taken as an example,and by comparing the initial capital cost and operating cost of two different voltages,the converter voltage is selected according to the principle of optimal comprehensive estimated costs.
