safety factor of insulation 绝缘可靠系数
At the same time,some insulation fault point and domain in generators can be predicted and even detected successfully, and the insulation safety analysis method and assessment model for large generator units are studied seriously.
本文研究了大型电站中的操作过电压冲击波在发电机定子绕组绝缘介质中暂态电场的实时分布状态，在线分析发电机的绝缘工作状况，搜索发电机内部可能突发绝缘事故的区域，预测发电机内部可能发生绝缘事故的故障点，并重点研究了大型发电机绝缘安全在线预测分析方法和建立了大型发电机绝缘安全评估模型。
