摘要： PROBLEM TO BE SOLVED: To enable spring force of a making spring in a switchgear operation mechanism to be safely constrained by a simple structure without using a large-scale dedicated jig, thereby making it possible to adjust the spring force by only inserting a spacer without removing the making spring part from the operation mechanism.SOLUTION: A spring bearing support medium 3 is disposed on the back of a spring bearing 5 which is disposed at an end of a making spring 4, and a screw hole for a jack bolt is opened in the spring bearing support medium 3 while penetrating therethrough. A jack bolt 10 is screwed into the screw hole, thereby pushing down the spring bearing 5 and the making spring 4 to form a clearance 16 between the spring bearing support medium 3 and the spring bearing 5. A spring force adjusting spacer 7 is inserted into the clearance 16, allowing the spring force to be adjusted by changing the working height of the spring.

摘要： PROBLEM TO BE SOLVED: To shorten a time for releasing cutoff spring force by a mechanism for operating a switchgear so as to shorten an open pole time as a whole. SOLUTION: The switchgear includes a roller pin 72a attached to a tip of a latch lever 72, a solenoid lever 54, and a latch 91 having a tip 102 rotating around a rotation axis of the solenoid lever 54 at a position different from the rotation axis of the solenoid lever 54, and engaged with the roller pin 72a. In shifting from the closed state to the cutoff state, the solenoid lever 54 is pushed and rotated by an electromagnetic solenoid for cutoff 21 so that the solenoid lever 54 is rotated in an opposite direction to a biasing direction of a solenoid lever return spring 54a, and the latch lever 72 is rotated by biasing force of the roller pin 72a to release engagement between the roller pin 72a and the tip 102 of the latch, which causes a cutoff spring to discharge its energy to rotate the latch lever 72.

摘要： 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.
