摘要
本文从理论与实际相结合的角度论述了湖南黄沙坪铅锌矿 5 5kW砂泵电动机变频器调速低限频率由 6Hz提高到 18Hz、同时又适当增大变频器输出电压最大整定值Um 的原因。
The paper discusses the reason that the lower limiting frequency of converter for 55kW sand pump motor used in Huangshaping Lead-Zinc Mine was raised from 16Hz to 18Hz,and the Max.Setting value Um of output voltage of the converter was raised.The paper also introduces the economic benefits reaped by adopted the converter in the mine.
