| 摘 要： | 介绍了一种用于快脉冲直线变压器的低电感多间隙气体开关。专门构造了多种形式的单通道放电实验，测量了在不同形态单通道放电时的开关电感，研究发现:单通道放电时开关电感除了受到角向电流的影响，还与电弧通道引起的放电回路面积变化有关，开关电感理论计算值与单通道放电时的实测结果最接近；开关在自放电和触发时，均形成了多通道放电，电感明显降低，触发时开关电感最小约为49 nH，电极角向电流的影响可以忽略。

| Abstract: | A six-stage gas switch with low inductance developed for fast linear transformer drivers (LTDs) is described, and the inductance of the switch with single channel and multi-channel discharges is investigated. The measured inductance of the switch with single channel discharge is consistent with the calculated results by the Nagaoka’s equation. It is affected by both the circuit loop area and the electrode azimuthal current. The triggered multi-stage switch with multi-channel discharges has the lowest inductance of 49 nH that is 4 nH more than that of the same sized cylinder, indicating that the azimuthal current along toroidal electrodes has little contribution to the inductance of the switch in practical operation. |
