| 摘 要： | 利用仿真软件建立变压器结构模型,对局部放电辐射的电磁波在箱体内的传播情况进行了仿真,并研究了变压器铁心、箱体缝隙对局部放电信号传播的影响。仿真结果表明,铁心和缝隙对电磁波的传播有衰减作用,在各个边角处会出现电磁波的最大幅值,在这些位置安装传感器有较好的检测效果。

| Abstract: | Transformer structure is modeled by simulation software to emulate the propagation characteristic of EM wave emitted by PD in transformers.The effect of transformer core and tank gap on signal propagation is discussed.The results show that EM wave propagation is attenuated by core and gap,and the maximal value of EM wave is appeared in the corner of transformers.The detection result will be preferable if transducer is fixed at these positions. |
