    • There is disclosed a coaxial lightning arresting structure comprising an inner conductor, an outer conductor surrounding the inner conductor and an arrester tube located between the inner and outer conductors perpendicularly to the direction of transmission and connected at its ends to the inner and outer conductors, respectively. The portion of the inner conductor provided with the arrester tube has a reduced effective sectional area as compared with the other portions of the inner conductor so that the ratio of the outer conductor inner diameter to the outer diameter of the inner conductor portion having the reduced effective sectional area is greater than the ratio of the outer conductor inner diameter to the inner conductor outer diameter at the other portions of the inner conductor which latter ratio provides the coaxial transmission line with a given characteristic impedance.
    • 公开了一种同轴避雷结构,其包括内部导体,围绕内部导体的外部导体和位于垂直于透射方向的内部和外部导体之间的避雷器管,并且其端部分别连接到内部和外部导体 。 设置有避雷器管的内部导体的部分与内部导体的其他部分相比具有减小的有效截面面积,使得外部导体内径与具有降低的有效的内部导体部分的外径的比率 截面面积大于内部导体的其他部分处的外部导体内径与内部导体外径的比率,后者的比例提供具有给定特性阻抗的同轴传输线。
