摘要：
The invention relates to a shielding element for the use in medium voltage switchgears with vacuum interrupters with at least two contacts, which are movable along a switching path between closed and open contact position, wherein the shielding element is positioned around the contact position region in the vacuum interrupter, wherein at least the inner surface of the shielding is applied with a topographic structure which is a rough or a structured surface, according to claim 1. In order to enhance the energy absorbance behavior of the at least the shielding, the implemented topographic structure is formed in such a way, that by given constant or approximately constant volume (Vi) of the shielding body, the surface ratio of the treated surface (S2) with implemented surface structure, and a untreated surface (S1) without topographic structure is greater than 1, so that this follows the condition V1 ~ V2 and S2/S1 >1.
摘要（中）：
本发明涉及一种用于具有至少两个触点的真空断路器的中压开关设备中的屏蔽元件，其可以沿着闭合和断开的接触位置之间的切换路径移动，其中屏蔽元件围绕接触位置区域 真空断路器，其中至少屏蔽体的内表面被施加有根据权利要求1的粗糙或结构化表面的地形结构。为了增强至少屏蔽的能量吸收行为，实施的地形 结构以这样的方式形成：通过给定屏蔽体的恒定或近似恒定的体积（Vi），具有实施的表面结构的处理表面（S2）和没有地形结构的未处理表面（S1）的表面比率是 大于1，使得遵循条件V1〜V2和S2 / S1> 1。
