Abstract: 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 In addition, the air in the interior of the buffering device (10) is withdrawn by a vacuum pump (38), and operating fluid (24) is thus introduced in a degassed condition.

Abstract: According to an embodiment, a switchgear operating mechanism has a roller pin rotatably fixed to a leading end of a latch lever. A latch is fixed to a solenoid lever at a position different from the rotation axis of the solenoid lever, and has a leading end engageable with the roller pin. In a state where the switchgear operating state is shifted from the closed state to the cutoff state, the solenoid lever is pushed by an electromagnetic solenoid for cutoff so as to be rotated in an opposite direction to the biasing direction of the solenoid lever return spring, and the latch lever is rotated by a biasing force of the roller pin to release an engagement between the roller pin and the leading end of the latch, which causes a cutoff spring to discharge its energy to rotate the latch lever.
Abstract translation: 根据实施例，开关装置操作机构具有可旋转地固定到闩锁杆的前端的滚子销。 闩锁在与电磁杠杆的旋转轴线不同的位置处固定到电磁杠杆，并且具有可与滚针接合的前端。 在开关动作状态从关闭状态切换到切断状态的状态下，螺线管杆被电磁螺线管推压，以便与电磁杠杆复位弹簧的偏置方向相反的方向旋转， 并且通过滚针的偏置力使闩锁杆旋转以释放滚子销和闩锁的前端之间的接合，这导致切断弹簧释放其能量以旋转闩锁杆。

Abstract: A switchgear operating mechanism for reciprocatively driving a movable contact of a switchgear so as to shift the switchgear between an open state and a closed state. In the closed state, a roller pushes a leading end of a latch in the direction substantially toward the rotation center of the latch. In a state where the switchgear operating state is shifted from the closed state to the open state, a lock lever is pulled so as to allow the latch to be rotated in the opposite direction to the biasing direction of a latch return spring to release an engagement between the roller and the leading end of the latch, which causes the opening spring to discharge its energy to rotate the sub-shaft.
