摘要
基于真空触发开关的导通机理,设计了长间隙真空触发开关导通特性的实验方案。根据高速摄像图片讨论了长间隙真空触发开关的导通过程和影响导通特性的因素。通过实验得到了触发电流对间隙脉冲电流的影响规律:采用上升时间较短且峰值较高的触发电流,能够明显降低主间隙的火花电阻和导通延时,验证了对导通过程的理论预测。
Based on the conduction mechanism of triggered vacuum switch,an experimental scheme has been designed to study the switching-on process of long-gap triggered vacuum switch.The switching-on process and the factors affecting the conduction characteristics of long-gap vacuum triggered switch were discussed according to photos gained from high speed camera.The factors affecting the spark resistance of triggered vacuum switch were analyzed.The experimental results confirm that the spark resistance and delay time can be effectively reduced by shortening the rise time and enhancing the peak of trigger current.The conclusion of experiment verifies theoretical predictions.
