The main shaft 1-4 of the single-shaft bidirectional resettable ratchet component 1 drives the second driving plate 5-1 to rotate anticlockwise for a certain angle, the shifting pin of the second driving plate 5-1 drives the second driven plate 5-2 to rotate clockwise for a certain angle gamma, so that the closing operation of the circuit breaker is realized, and the first driven plate 2-2 keeps in place under the action of a locking arc; as shown in fig. 14a, when the operation handle 1-1-1 is rotated counterclockwise by an angle smaller than α, the second driven dial 5-2 has been rotationally moved to an angle γ. At this time, the circuit breaker completes the closing operation, and the closing operation of the circuit breaker is in place, as shown in fig. 14b and 14c, wherein the full sectional view section of fig. 14b is the section E-E of fig. 9b, and the full sectional view section of fig. 14c is the section D-D of fig. 9 b. When the operating handle is continuously operated to rotate anticlockwise to an angle alpha, the main shaft 4 of the circuit breaker returns under the action of the return device; after the operation is completed again, the operating handle returns to the initial position under the action of the bidirectional torsion springs 1-1-3, and the clockwise moving device moves counterclockwise to the position schematically, as shown in fig. 15a, the positions of the disconnecting switch opening/closing device and the circuit breaker opening/closing device are respectively shown in fig. 15b and 15c, wherein the full-section cross section of fig. 15b is the cross section E-E of fig. 9b, and the full-section cross section of fig. 15c is the cross section D-D of fig. 9 b. When the breaker is in a closing state, the isolating switch is in the closing state, the clockwise device can move in two directions, but only clockwise movement is effective operation, and the opening operation of the breaker can be realized.
As shown in fig. 11a to 15c, the clockwise operation of the clockwise device is realized by the same principle as the counterclockwise operation, and therefore, only the counterclockwise operation is described.
