摘要： A ground test switch comprises a terminal plate electrically connected to a movable contact member but electrically insulated from a closed vessel enclosing a high-voltage conductor, a grounding conductor disconnectably electrically connecting the terminal plate to a member maintained at ground potential, and a locking device locking the movable contact member against movement when the grounding conductor is detached from the connecting position. The operator may forget to mount the grounding conductor in the switch again after a ground test. Such a trouble can be readily detected because the movable contact member is locked against movement.
摘要翻译：地面测试开关包括电连接到可动触点构件但与封闭高压导体的封闭容器电绝缘的端子板，可断开地将端子板电连接到保持接地电位的构件的接地导体，以及锁定装置当接地导体从连接位置脱离时，锁定可动接触件防止移动。地面试验后，操作者可能会忘记将接地导体重新安装在开关中。可以容易地检测到这种麻烦，因为可动接触构件被锁定以防止运动。

摘要： A compact-type gas-insulated switchgear apparatus is disclosed, in which movable contacts of a disconnector and a ground switch arranged in a cable head casing are adapted for switching operation in parallel to the axis of the cable head casing. A connecting conductor connecting stators of the disconnector and the ground switch is arranged in a position perpendicular to the axis of the cable head casing. A connecting opening is formed in the side wall of the cable head casing at a part thereof corresponding to the end of the connecting conductor. It is thus not necessary to increase the diameter of the cable head casing for the movable contacts of the disconnector and the ground switch performing substantially parallel operation, and other electrical equipment may be connected along the extention of the connecting conductor connecting the stators of the disconnector and the ground switch without modifying the cable head casing.
摘要翻译：公开了一种紧凑型气体绝缘开关设备，其中布置在电缆头壳体中的隔离开关和接地开关的可动触头适于与电缆头壳体的轴线平行地切换操作。连接断路器的定子和接地开关的连接导体被布置在垂直于电缆头壳体的轴线的位置。在电缆头壳体的侧壁形成有与连接导体的端部对应的部分的连接开口。因此，不需要增加用于隔离开关的可动触头和基本并联操作的接地开关的电缆头壳体的直径，并且可以沿着连接导线的连接导线连接其他电气设备，连接导体连接断路器的定子和接地开关，无需修改电缆头套管。
