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 In addition, the air in the interior of the buffering device (10) is withdrawn by a vacuum pump (38), and operating fluid (24) is thus introduced in a degassed condition.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

摘要： 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.

摘要： The present invention provides a switchgear, which can achieve miniaturization and simplification while securing high operation reliability, and excellent in assembly, operability and inspection, and further, has a compact size. A fluid pressure operating section is provided in a mechanical box arranged on a lower end portion of a support porcelain tube. Insulated operating rods are received in the support porcelain tube, and connecting mechanisms are received in a container. Switching contacts of circuit breaker and disconnecting switches and the fluid pressure operating section are connected via the connecting mechanisms and the insulated operating rods.
