直流真空断路器永磁斥力机构运动特性监测系统研究

Gaoya dianqi
针对短行程直流真空断路器永磁斥力机构运动速度快、动态参数多且难以精准监测的问题，文中设计了一种多参数动态特性监测系统。以400 V/400 A/25 kA直流真空断路器永磁斥力机构为研究对象，采用光耦隔离技术采集分合闸线圈电压模拟信号，同时采用传感技术和二阶滤波的方式对电流信号与位移信号进行降噪采集，并基于C#自主开发上位机显示界面，实现短行程快速操动机构多参数的实时同步显示。通过与高精度电流传感器和机械特性测试仪监测参数的比对分析可知，系统采集误差可控制在3.5%以内。

耦合磁吹和触头运动的直流接触器电弧特性研究

Gaoya dianqi
磁吹结构和运动机构特性是影响直流接触器电弧开断性能的重要因素。文中引入灭弧室中非均匀磁场分布与动触头运动特性的耦合影响，构建了电、磁、气流、温度等多场耦合的二维电弧磁流体动力学仿真模型，分析了不同磁吹结构、反力弹簧刚度系数、触头超程等参数对直流电弧特性的影响。搭建了直流接触器电弧特性实验平台，开展了对比实验验证仿真结果。研究表明：提出在静触头之间增加中间永磁体的两种新型磁吹结构，较原结构燃弧时间分别缩短20.2%与14.7%，在电极下方磁吹结构增加中间永磁体的提升效果更好；反力弹簧刚度系数的最优选择为1.
