【摘要】

：

针对牵引变压器油中金属颗粒群引起的放电问题,以Fluent软件为计算工具,采用固-液两相流理论中的Euler-Lagrange方法,模拟牵引变压器内部油道中运动金属颗粒群的分布状态.用标准k-ε湍流模型对流动的变压器油进行描述,同时用颗粒轨道模型对油中金属颗粒群进行描述.在对颗粒轨道模型进行定义时,从颗粒受力情况、颗粒湍流扩散以及固-液两相耦合3方面进行设置,从变压器油中金属颗粒尺寸、油流速度和油

强电场下干式空心电抗器分支电流测试系统稳定性

由于产品材质不均等原因导致电抗器线匝的分布电流不均,从而会导致干式空心电抗器局部过热低绝缘性能,因此我们需要对电抗器个包封层的电流进行测试.本文通过使用干式空心电抗器分支电流测试系统,在工程现场测量电抗器每个分支值电流的实际数据，并以无线通讯的方式将数据接收到pc终端。通过实验可知，干式空心电抗器分支电流测试可在强电场下电抗器各包封层的电流值，这将为研究干式空心电抗器因分支电流不均造成的故障提供重
