近年来,低SF6混合比的SF6/N2混合气体开始作为绝缘介质在气体绝缘金属封闭输电线路(Gas-insulated Metal-enclosed Transmission Line,GIL)中得到逐步应用,以替代纯SF6气体.为了在电力设备中更好地应用SF6/N2混合气体,本文在工频电压下,通过实验分析研究了不同电场均匀度下较低SF6混合比的SF6/N2混合气体的击穿特性,并在极不均匀场下研究了局
内部局部放电是电力变压器绝缘劣化和事故的主要原因,局部放电测试对保证电力设备安全运行有重要意义.通过JFD-251局部放电检测系统,建立不同电极形状的放电模型模拟电力设备内部局部放电故障,测试了电力设备内部局部放电特征值,包括放电起始电压、尖端放电电压、熄灭电压等.采用新式光纤传感器进行了局部放电测试研究,试验发现放电脉冲间隔随着试验电压的增大而减小,光纤传感器测得的放电量与局部放电测试仪测得的放
架空输电线路微风振动是导致导线疲劳损伤的主要原因，导线动弯应变是表示疲劳损伤程度的一个主要参数，但在现行条件下无法直接测量这个参数。本文研究了基于光纤传感原理的输电线路微风振动在线监测技术,通过理论计算验证了以植入光纤光栅的悬臂梁为主体结构的新型无源传感器设计的可行性,依据计算结果指导成功试制出首个光纤光栅式微风振动监测传感器,同时根据光纤光栅的应力变化与导线微风振动中振幅及频率的变化情况对传感器
