摘要
为消除电网中变压器绕组变形引起的事故隐患,文章根据频率响应法在嘉兴电网中应用的实际情况,在4年多的时间内对所辖的500kV主变压器1台/次、220kV主变压器28台/次,110kV主变压器156台/次进行了多次现场测试,研究得出了在现场应用该方法测试对变压器绕组变形的频响曲线几种影响因素,同时,提出利用频响法测绕组变形的注意要点。
To eliminate the hidden trouble of accident in power network caused by winding deformation of transformer, this paper introduces several factors of effect on frequency response of winding deformation of transformer using frequency response method, combined with the actual application of this method in Jiaxing Power Network, in which many times of tests on - the - spot have been carried out during the past more than 4 years: 1 time for 500 kV main transformers; 28 times for 220 kV main transformers; 156 times for 110 kV main transformers. At the same time, the notice points for using frequency response method to measure winding deformation are put forward.
