| 摘要: |
| 介绍了变频调速系统检查项目及维护内容，指出变频调速系统出现故障除参数(如U／f曲线)设置不当外．主要有外部和变频器本身的原因，而外部原因居多。给出了变频调速系统故障分析与处理的一般步骤，并列举了故障诊断实例，对维护变频调速系统的正常运行有所借鉴。 |

| Abstract: |
| The maintenance of variable frequency speed regulation system is introduced. Besides the parameters setting,the U/f curve as an example,the system faults are caused mainly by the external factors rather than the converter itself. The general steps of system fault analysis and treatment are presented with some examples of fault diagnosis, which provides references to the maintenance of variable frequency speed regulation system. |
