基于实测和Matlab仿真波形比较的10 kV配电网单相接地故障暂稳态特征信息融合选线方法研究

Dianci bileiqi
10 kV配电网单相接地故障稳态选线方法受故障电阻、谐振接地电网补偿的影响较大，且信噪比较低；而暂态选线方法虽然信噪比较高，且受故障电阻、谐振接地电网补偿的影响较小，但具有依赖特征频带选取以及信号持续时间短，信号与暂态干扰信号产生混叠严重的特点。为了进一步提高选线成功率，本研究探索了一种融合暂稳态特征信息的选线方法，通过在Matlab仿真平台中搭建10 kV配电网系统的高精度pi模型网络，分析故障信号的暂稳态特征，在三相不平衡、支路开合闸等干扰条件下 ...

集成式真空断路器永磁操作机构主要参数设计

Gaoya dianqi
针对传统永磁真空断路器体积大、重量重、在狭小空间运行成本高的问题，提出了一种真空灭弧室和永磁操作结构一体化设计方案。将传统的真空灭弧室与永磁操作结构并列布局改为垂直布局，永磁操作机构中的保持部分与驱动部分直接作用于触头组件，与传统永磁断路器相比体积减少二分之一。集成式断路器新型永磁机构采用单线圈双向激励驱动，无需像传统双稳态断路器分别对分合闸线圈通电；并将圆环状永磁体切割为规律排列的瓦片型，优化磁路布局。建立永磁机构静磁—电磁—动力学物理场仿真模型，提出基于NSGA-III（第三代非支配遗传算法 ...
