根据文献[1],我们研制了低气压间隙去耦式短路开关,并研究了其性能. 短路开关的结构如图1所示,由上、下两部分组成:上部是高气压间隙Gh,工作介质为CO2,压强在1-2.5kg/cm2之间;下部是低气压间隙G1。工作介质是空气,压强为20mTorr.间隙的电极材料是黄铜,端面镶有不锈钢.以汽车的 According to the literature [1], we developed a low-pressure clearance decoupling short-circuit switch, and studied its performance.The structure of the short-circuit switch shown in Figure 1, from the upper and lower parts of the upper part is the high pressure gap Gh, work The medium is CO2, the pressure is between 1 and 2.5 kg / cm2, and the lower part is the low pressure gap G1. The working medium is air, the pressure is 20mTorr. The gap of the electrode material is brass, stainless steel end face inlaid with the car
