Energy Coordination Relationship Between ZnO Varistor Stages Under the Action of Nanosecond Pulse
针对纳秒级的强电磁脉冲对电力系统的损害问题,基于压敏电阻的特性和瞬变场传输理论,通过改变脉冲注入电压分析不同参数的压敏电阻在20/500-550 ns波形下的响应特征,结合滤波器理论,利用ADS(Advanced Design System)仿真软件进行设计,仿真结果为在频率50 Hz以内插入损耗小于0.3 dB的巴特沃斯低通滤波器,将滤波器串联在两片伏安特性相同的压敏电阻中间进行脉冲注入测试.实验结果表明:随着注入电压的增大,单片压敏电阻的过冲…查看全部>>
