摘要： High-voltage metal-clad gas-insulated switchgear apparatus wherein an isolator switch is mounted in a gas-filled earthed casing to isolate one conductor part of the apparatus from the other, and an earthing switch mounted on the casing includes a movable contact member operable to engage and effect earthing of the isolatable conductor part by connecting the latter to the earthed casing. A measuring electrode mounted within the casing and insulated therefrom forms part of a capacitive voltage divider from which is derived a voltage the magnitude of which indicates whether the contacts of the isolator switch are open or closed.

摘要： The present invention relates to a gas switch provided with a body case wherein a switching unit is installed and an arc-extinguishing gas such as sulfur hexafluoride (SF6) or the like is enclosed at a constant pressure, and an actuating mechanism for operating the switching unit. When a pressure of the arc-extinguishing gas comes lower than a predetermined value, a lock member is disposed to a working position whereat it engages with the actuating mechanism, the actuating mechanism is thus locked unoperatably, and a display member is ready for observing externally in accordance with a shift of the lock member. Operators then carry out works for maintenance and check of the gas switch as ensuring the state wherein a gas pressure drops in the body case and the actuating mechanism has been locked.
摘要翻译：本发明涉及一种设置有主体壳体的气体开关，其中安装有开关单元，并且在恒定压力下封闭诸如六氟化硫（SF6）等灭弧气体，以及用于操作开关的致动机构单元。当灭弧气体的压力低于预定值时，锁定构件设置在与致动机构接合的工作位置处，致动机构因此被不可操作地锁定，并且显示构件准备好在外部观察根据锁定构件的移动。然后，操作员进行维护和检查气体开关的工作，以确保气体压力在主体壳体中下降并且致动机构已被锁定的状态。
