提高空预器电机运行可靠性的实践

Practice of Improving the Operation Reliability of Air Preheater Motor

空预器对于火力发电厂是十分重要的设备,为保障其可靠运行,某厂利用检修停机的机会,对300MW机组空预器的电气回路进行改造,基本上解决了空预器不明原因跳闸等问题,目前改造后的电气回路运行正常,无缺陷发生。

The air preheater is a very important equipment for thermal power plants.In order to ensure its reliable operation,a plant took the opportunity of maintenance and shutdown to transform the electrical circuit of the air preheater of a 300MW unit,which basically solved the unknown cause of the air preheater for problems such as tripping.The electrical circuit after the transformation is currently operating normally without defects.
