摘要：

变频器控制回路的设计不合理会给变频器安全、稳定运行造成隐患。以云浮发电厂6kV风机变频器故障为例，对风机变频器故障原因进行了分析，指出高压变频器内部控制

回路设计不合理及元件存在质量问题是高压变频器故障的症结所在，提出了防范措施，以减少因故障造成的各种损失。

Abstract:

The irrational design of control circuit of frequency converter may cause hidden trouble for safe and stable operation of the frequency converter.

Taking the fault of the frequency converter for the 6kV draft fan in Yunfu Power Plant as example, the reasons of the fault were analyzed. It was pointed

out that the irrational design of the inner control circuit of the highvoltage frequency converter and the poor quality of the elements are the crucial

reasons of the fault of the highvoltage frequency converter. The preventive measures were put forward to reduce various losses caused by the fault.

Key words: high-voltage frequency converter, reason of fault, control circuit, preventive measure
