直接空冷系统风机变频器群水冷系统研究

Direct air cooling system fan frequency converter group water cooling system study

直接空冷系统变频器布置集中,夏季高温天气下变频器群运行时经常超温报警,影响电厂安全、稳定、高效运行。对变频器群超温报警原因进行分析,提出了外加水冷系统的解决方案,实际运行效果良好且节能环保,有效延长了变频器的使用寿命。

Direct air cooling system frequency converter usually aligned concentratedly,and often caused over temperature alarm in summer. After cause analysis,the plan that adds water cooling system was introduced. Actual operation proved that this plan is effective and able to save energy and prolong converter life-span.
