摘　　要：本文中作者提出了一种绕组温度间接测量的方法,首先建立了一套绕组温度测量模型,然后基于一阶响应函数建立绕组温升暂态模型,最后基于该测量方法搭建了一套绕组温度测量系统。经测试该方法能精确模拟绕组暂态温升,从根本上解决绕组温度测量不准确的问题,具有较高的应用价值。A method of winding temperature indirect measurement is proposed by the authors in this paper.First,establish a measurement model of winding temperature,then establish a dynamic model of winding temperature rising.Lastly,build a winding temperature measurement system based on these models.The method in this paper can accurately simulate the dynamic temperature rise of winding,solve the problem of inaccurate winding temperature measurement fundamentally,and has high application value.
