Abstract: PROBLEM TO BE SOLVED: To provide an operating device for a switch which is suitable for the case where the high speed motion is required by only one of the open-circuit and close-circuit sides, and is compact, simple lightweight and highly reliable. SOLUTION: The operating device for the switch serves for on-off operation of the switch by converting the rotational motion of a main rotation main shaft 8 to those of the open-circuit and close-circuit and comprises a drive spring 9, drive operation means and retaining mechanism 4. One side of the drive spring 9 is fixed to the main rotation main shaft 8. While energy is stored by the rotation of the main rotation main shaft 8, its energy release proceeds with the high speed motion of the contact of the switch. The drive operation means are provided with a manual operation shaft 1. The rotation of the manual operation shaft 1 is transmitted by a small gear 2 to a large gear 3. In parallel with operating one of the open-circuit and close-circuit by rotating the main rotation main shaft 8 through the retaining mechanism 4 and lever 5, the energy of the drive spring 9 is stored. The retaining structure 4 retains a first roller 6 of the lever 5 fixed to the main rotation shaft 8 to keep the drive spring 9 via the main rotation main shaft 8 in an energized state.

Abstract: PROBLEM TO BE SOLVED: To shorten the time required before releasing the breaking spring force in an operation mechanism of a switchgear.SOLUTION: When the switchgear transits from a closing state to a breaking state, a solenoid lever 36 is pushed by the plunger 38a of a breaking electromagnetic solenoid 38 and rotated so that the solenoid lever 36 rotates in the direction opposite from the urging direction of a solenoid lever reset spring 37. Consequently, a trigger roller pin 31a and the solenoid lever 36 are disengaged, and an eccentric pin 32 and a trigger lever 31 are rotated by an urging force from a latch roller pin 12a. The latch roller pin 12a and the tip of the latch 34c are thereby disengaged, and a latch lever 12 is rotated by release force of the breaking spring.
