摘要
针对国内某大型水轮发电机励磁引线烧毁事故,从发电机发生事故时的安装情况、运行状况、励磁引线的材质、机械变形及引线温升对绝缘材料影响等几个方面进行了分析,对于大型水轮发电机励磁引线的截面设计、材料选择及受力情况、大型水轮发电机组安装和检修提出了建议,具有一定的借鉴作用。
Aiming at the burning accident of one large hydraulic turbine generator, analysis is performed in terms of installation, opera-tion, excitation lead material, mechanical deformation, and impacts on insulating materials from the lead temperature rise, etc.Section design, materials selection and action of the excitation lead as well as large unit installation and maintenance are commented.These anal-ysis and comments provide reference to similar occurrence.
