摘要(Abstract)：

我国正在建设张北±500 kV柔性直流电网示范工程,混合式高压直流断路器是其关键控制和保护设备。快速机械开关单元是混合式直流断路器的关键部件,采用电磁操动机构,机械动作过程涉及电磁场、热场和机械位移场,需要进行多场耦合仿真优化设计。该文开展高速机械开关单元多场耦合仿真优化设计。首先,设计一种基于双线圈推金属盘驱动与双稳态弹簧保持操动机构的高速机械开关单元结构。然后,针对高速机械开关单元动作过程,提出一种能全面反映机构运动、触头碰撞和线圈温升情况的电磁场、热场和运动场多场耦合计算方法。最后,进行高速机械开关单元多场耦合仿真优化设计。初步确定高速机械开关性能提升关键因素,重点分析不同斥力线圈匝数对分闸时间、线圈允许温升及分闸反弹等关键技术指标影响,最终确定高速机械开关各项最优技术参数。仿真结果表明,该文设计高速机械开关单元能在1.8 ms内分闸到达额定绝缘开距,满足技术要求。该文的优化设计为混合式直流断路器快速机械开关优化设计提供理论指导,对于其他快速机械开关设计也有重要参考价值。
