Cathode-anode spacer comprising a projection of a length limited relative to its distance to the cathode
摘要：
For use in vacuum between a cathode (21) and an anode (23) with avoidance of surface flashover resulting from a voltage supplied between the cathode and the anode, a dielectric spacer (25) has a side surface and a projection (27) protruded perpendicularly of the side surface. The projection has a length of projection from the side surface, a cathode side end having a cathode distance relative to the cathode, an anode side end, and a thickness having a center plane between the cathode and the anode side ends and nearer to the cathode than to the anode, a ratio of the length of projection to the cathode distance being not less than 0.4. The cathode comprises no protrusion in a face to face relation to the anode side end. It is possible to use the dielectric spacer between two electrodes supplied with an AC voltage.
摘要（中）：

为了避免在阴极和阳极之间提供的电压引起的表面闪络，阴极（21）和阳极（23）之间的真空中使用，电介质间隔物（25）具有侧表面，突出部（27）突出 垂直于侧面。 突起具有从侧面突出的长度，阴极侧端部具有阴极相对于阴极的距离，阳极侧端部和具有阴极和阳极侧端部之间的中心面并且更靠近阴极的厚度 与阳极相比，投影长度与阴极距离的比值不小于0.4。 阴极不包括与阳极侧端面对面的突起。 可以使用提供有交流电压的两个电极之间的电介质间隔物。
