回転により開閉器が投入状態になる。When the spring energy storage shaft 10 is normally rotated counterclockwise at the time of closing, as shown in FIG. 3, the closing spring 13 is moved upward by the positive rotation of the energy storing lever 12 to make the closing spring. 20 is compressed and stored. When this energy is stored,
The biasing force of the opening spring 25 does not act. Then, near the end of the charging of the closing spring 20, that is, at the time of maximum energy storage, the closing energy storing pin 13 abuts against the closing latch lever 27 and presses it.
As the closing latch pin 6 and the closing latch lever 27 are disengaged and the closing spring 20 is released, as shown in FIG. 4, the main spindle lever 5 rotates counterclockwise in the positive direction, and the main shaft 3 rotates in the positive direction. The switch is turned on.
