摘要： A piston rod (15) and a first piston (13) are arranged in the interior of an external cylinder (11) and internal cylinder (12); a second piston for absorbing the change of volume of operating fluid (24) is also arranged therein. Also, a first return spring (18) for returning the piston rod (15) to the interruption position is provided and a second return spring (20) for returning the operating fluid 24 into the high-pressure chamber (25) by pressurizing the second piston (14) is provided. In addition, the air in the interior of the buffering device (10) is withdrawn by a vacuum pump (38), and operating fluid (24) is thus introduced in a degassed condition.

摘要： A switchgear and an operating mechanism thereof which stably maintain a spring force by a shutoff spring, and reduce an opening time. The operating mechanism includes a main lever that rotates upon receiving the spring force by a shutoff spring released in a transition to a shutoff condition to move a movable contact apart from an opposing contact, and the main lever is linked with a sub lever fixed to a sub shaft rotatable around its shaft. The sub shaft is fixed with a latch lever with a roller attached to the tip thereof. The latch lever is prevented from rotating by a latch present on a movement trajectory of the roller. A weight is pushed against the latch in a separable manner, and the weight is pushed by an actuator to allow the latch to rotate, thereby being retracted from the movement trajectory of the roller.
