    Abstract: Time delay means for actuating a protective bypass switch for series capacitors comprising a bellows device containing a gaseous medium, a valve means pneumatically connected to the bellows, and an adjustable control orifice device, the control orifice being effective to release the gaseous medium from the bellows at a predetermined rate when an overcurrent condition is sensed on the line, the bellows being effective to actuate the protective switch a predetermined time after the overcurrent is sensed.

    Abstract translation: 时间延迟装置,用于启动用于串联电容器的保护旁路开关,其包括包含气体介质的波纹管装置,气动连接到波纹管的阀装置和可调控制孔装置,所述控制孔有效地将气态介质从波纹管 当在线路上检测到过电流状况时,以预定的速率,波纹管在感测到过电流之后的预定时间内有效地致动保护开关。
