摘要: 设计制作了一个有多通道连接的类似轨道的平行电极结构的开关，给出了开关的结构，对开关内的电场分布做出分析，利用Pspice软件对安装在实验装置中的开关的电压电流进行了计算。实验测得此开关在实验系统中耐压约为500 kV，导通时通过阻值为1 kΩ的水电阻负载的电流为400 A左右。实验所得电压电流波形与模拟结果基本吻合。实验证明此开关具有体积小、更适于平板传输线的结构等优点。

Abstract: In this paper a rail-like switch with multi-channel connected with parallel electrodes is designed and manufactured. The structure of the switch is illustrated and the internal electric field distribution is simulated by an electromagnetic simulation code. The voltage and current of the switch installed in the experiment setup are calculated using the software Pispice. Meanwhile experiments give the voltage and current of the switch, which are basically agreed with those from experiments. Experiments also indicate that the breakdown voltage of this switch is about 500 kV and the current of water-resistance of 1 kΩ is about 400 A. This work shows that this switch is compact and suitable to connect with parallel-plates transmission line.-
