广州换流站408329号换流变压器的网侧绕组更换（Replacement of the Line-side Winding for No. 408329 Converter Transformer in Guangzhou Converter Station）
换流变压器 网侧绕组 负载损耗
2010/8/17
针对利用色谱分析发现的广州站408329号换流变压器的重大缺陷，在检修时采用单一线规绕制两个网侧新线圈并进行整体替换。仿真计算表明，该方案实施后可消除环流损耗，但横向涡流损耗会稍为增加，总体负载损耗基本不变。出厂试验数据显示，各项关键性指标如局放量、温升后的色谱结果、总损耗等均接近甚至优于出厂值，表明修复工作取得了圆满成功。
