600 MW机组发电机转子匝间短路分析与处理

Analysis and Treatment of Short Circuit between Turns of Generator Rotor of 600 MW Unit

近几年,大型火力发电机组发电机转子匝间短路故障呈上升趋势,对发电机组整体的长期安全运行造成较大影响。本文结合某电厂600 MW机组发电机转子匝间短路故障分析判断,提出发电机短期和长期处理措施,给出修复和改进方案,防止同类事故的发生,确保发电机安全可靠运行。

In recent years,the inter turn short circuit fault of large thermal power generator rotor is on the rise,which has a great impact on the long-term safe operation of the whole generator.Combined with the analysis and judgment of the interturn short circuit fault of the generator rotor of a 600 MW unit in a power plant,this paper puts forward the short-term and long-term treatment measures of the generator,and gives the repair and improvement scheme,so as to prevent the occurrence of similar accidents and ensure the safe and reliable operation of the generator.
