| 摘要: |
| 为了提高电磁斥力高速开断器的介质恢复特性，在建立电磁斥力高速开断器斥力仿真模型的基础上，优化了外部驱动电路的电气参数，获取了可以将开断速度提升至37.2 m ／s的参数方案，这个速度与爆炸辅助开断速度相当。设计了包含电流回路、强迫换流回路以及高压回路的强迫换流型介质恢复试验电路，完成了21.6、37.2 m ／s这2种开断速度条件下的介质恢复性能分析试验，并将试验结果进行对比。另外，对介质恢复过程进行了高速摄像。试验示波图和照片说明，所提电磁斥力高速开断器斥力仿真模型是正确的，提升开断速度可以有效优化电磁斥力高速开断器的介质恢复特性。 |

| Abstract: |
| In order to improve the dielectric recovery characteristic of high-speed electro-magnetic repulsion isolator，the electrical parameters of external drive circuit are optimized based on its simulation model to obtain the parameter scheme for increasing the breaking speed to 37.2 m／s，which is nearly equal to the explosion assist breaking speed. A forced commutation dielectric recovery circuit composed of current loop，forced commutation loop and high-voltage loop is designed，based on which，the analytical experiments of dielectric recovery performance under the breaking speed of 21.6 m／s and 37.2 m／s are carried out and the results are compared. In addition，the photos of dielectric recovery process are shot by high-speed camera with these two speeds. Both experimental results and photos illustrate that，the simulation model is correct and the higher breaking speed can effectively optimize the dielectric recovery characteristic of high-speed electro-magnetic repulsion isolator. |
