    • The invention relates to a post insulator (4) whose surface (41, 51) is geometrically configured, in at least one area (4a) between an inner conductor (2) and encapsulation (3) for a gas-insulated switchgear assembly (1) such that surface discharge paths (6b) are provided between the inner conductor (2) and the encapsulation (3) and have a subsection in the opposite direction to the bridging direction (7). In consequence, surface discharges (6a) can be diverted in the opposite direction to an original propagation direction (7), and come to rest by self-blocking. Exemplary embodiments relate to: an indentation (4b) which is concave and is open toward the inner conductor (2) and/or toward the encapsulation (3) and is formed between a cup shaped barrier (5) and the base body (40) of the post insulator (4); diversion of surface discharges (6a) through up to 180° for efficient self blocking; and adhesive bonding (45) of the barrier (5) on a conventional post insulator (4). The invention also relates to a gas-insulated switchgear assembly (1) or to a switchgear assembly module having such a post insulator (4) or partition insulator (4).
    • 本发明涉及一种后表面(41,51)几何构造的后绝缘体(4),位于用于气体绝缘开关设备组件(1)的内部导体(2)和封装(3)之间的至少一个区域(4a)中 ),使得表面排出路径(6b)设置在内部导体(2)和封装(3)之间,并且具有与桥接方向(7)相反的方向的子部分。 因此,表面放电(6a)可以沿与原始传播方向(7)相反的方向转向,并通过自我阻挡而休息。 示例性实施例涉及:凹陷(4b),其凹入并且朝向内导体(2)和/或朝向封装(3)开口,并且形成在杯形屏障(5)和基体(40)之间, 的后绝缘体(4); 将表面放电(6a)转移到180°以实现有效的自我阻挡; 以及在常规的柱绝缘体(4)上的阻挡层(5)的粘合(45)。 本发明还涉及一种气体绝缘开关设备组件(1)或具有这种立柱绝缘体(4)或分隔绝缘体(4)的开关组件模块。
