美国谷轮公司压缩机应用技术讲座 第十三讲 压缩机常见故障分析(1)——电机烧毁

COPELAND COMPRSSOR APPLICATION ENGINEERING 13. COMPRESSOR FAILURE ANALYSIS (1) -MOTOR BURNOUT

绕组烧毁是压缩机常见故障。绕组烧毁前制冷机的用户不容易发现,而绕组烧毁后掩盖了一些导致烧毁的现象,给事后分析增加了难度。本文对电机负荷过大,电压异常,散热不足和绕组绝缘破坏几方面进行了分析,提示了这些因素与电机损坏之间的关系,以引起用户对异常因素的重视。

Winding burnout is one of the main phenomenon of compressor failure which is not easy to be found beforehand by compressor users. Burnout of winding covers some of the proof that accounts for the failure, making it difficult to investigate the root causes of the accident. Abnormal power supply, overload, inadequate cooling, winding insulation failure and the influence of these factors to motor winding are analyzed in this paper to draw the attention to these factors to prolong the motor life.
