    • Variable electric field balancing device formed by a hollow assembly that, with geometric shapes that can be different on the outside, comprises an upper passive capture element (2), as a capture electrode, a lower passive capture element (3), as a reception electrode, and an insulator element (4) that keeps them separated from each other at a distance (d) dependent on the conductivity coefficient of the materials, and that, also, externally covers the lower element (3) like a skirt to the lower base of the same, preventing the impact of a lightning bolt on said lower element (3) from being able to induce the generation of an upward leader, and there is also an expansion and compression valve (5) that connects the outside to the inside of the hollow assembly and which expands in phases of passage of current and/or absorption of external induced surges, and compressed at the end of the compensation of the field.
    • 通过中空组件形成的可变电场平衡装置,其具有在外部可以不同的几何形状,包括上部被动捕获元件(2),作为捕获电极,下部被动捕获元件(3),作为接收器 电极和绝缘体元件(4),其根据材料的导电系数使它们彼此分开距离(d),并且还将下部元件(3)外露到裙部到下部 的基部,防止所述下部元件(3)上的闪电的冲击能够引起向上引导件的产生,并且还存在将外部连接到内部的膨胀和压缩阀(5) 并且在外部引起的浪涌的电流和/或吸收的通过阶段膨胀,并且在场的补偿结束时被压缩。
