摘要： Herein disclosed is a gas switch comprising: a body casing having an arc-extinguishing gas such as the SF6 gas and the like confined therein; bushings having their inner end portions inserted into said body casing; a rod-shaped stationary electrode and a hollow stationary electrode attached to the inner end portions of the bushings movable electrodes contacting with the rod-shaped stationary electrode at all times and made movable into and out of contact with said hollow stationary electrode; insulated bearing sleeves bearing the movable electrodes, respectively; a plurality of rocking arms for rocking in association with the turn of a drive shaft so that the movable electrodes are linearly moved through the insulated bearing sleeves by the rocking motions of the rocking arms to open and close the gas switch; and a connecting mechanism for connecting the rocking arms to the insulated bearing sleeves, respectively. The connecting mechanism includes: engaging grooves formed in the outer sides of the insulated bearing sleeves and opened at their sides facing the drive shaft; and engaging projections so formed in portions of the rocking arms as to directly engage with the engaging grooves and allowing in their engaging states the rocking arms to rock in the engaging grooves.

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： Herein disclosed is a gas switch comprising: a body casing having an arc-extingushing gas such as the SF6 gas and the like confined therein; bushings having their inner end portions inserted into said body casing; a rod-shaped stationary electrode and a hollow stationary electrode attached to the inner end portions of the bushings movable electrodes contacting with the rod-shaped stationary electrode at all times and made movable into and out of contact with said hollow stationary electrode; insulated bearing sleeves bearing the movable electrodes, respectively; a plurality of rocking arms for rocking in association with the turn of a drive shaft so that the movable electrodes are linearly moved through the insulated bearing sleeves by the rocking motions of the rocking arms to open and close the gas switch; and a connecting mechanism for connecting the rocking arms to the insulated bearing sleeves, respectively. The connecting mechanism includes: engaging grooves formed in the outer sides of the insulated bearing sleeves and opened at their sides facing the drive shaft; and engaging projections so formed in portions of the rocking arms as to directly engage with the engaging grooves and allowing in their engaging states the rocking arms to rock in the engaging grooves.
