摘要： A device for controlling a breaker comprising a weight (48) provided in the vicinity of a releasing trigger (19) and an auxiliary spring (50 )for urging the weight (48) so that the weight (48)is in contact with the releasing trigger (19). An equivalent mass of the weight (48)is about one-third of an equivalent mass of the releasing trigger. When the releasing trigger (19)is in contact with a pin (45) of a releasing latch (18), the weight (48)rebounds but the releasing trigger (19)is settled without rebounding. By such a structure, the rebound of releasing latch and the releasing trigger is prevented when these are engaged, whereby a time for closing a circuit is shortened.

摘要： A compact, lightweight and low-cost operating apparatus for a switchgear include a second cam (50) turned counterclockwise by an electric motor begins to maintain contact with a closing lever (37) at a first angular position (POS1), turns the closing lever (37) counterclockwise to energize a circuit-making coil spring (77), and causes a closing latch (48) to lock the closing lever (37). The second cam (50) further turning counterclockwise becomes separated from the closing lever (37) and actuates a cam switch (156) at a second angular position (POS2) to interrupt an electric current supplied to the electric motor. The second cam (50) further turns due to inertial turning of the electric motor and is braked by a elastic brake member (159) at a third angular position (POS3), whereby the second cam (50) stops within a specific angular range &Dgr;&thgr; of rotation. Despite its simple structure, the elastic brake member (159) can halt the second cam (50) in a reliable fashion.

摘要： A make break switchgear includes a first breaking lever receiving a torque in a counterclockwise direction, a second breaking lever connected through a linkage to the first breaking lever, and a making lever receiving a torque in a clockwise direction. These elements are supported by a main shaft and are rotatable. When a circuit is completely opened by the switchgear, a guide guiding a rotor on an arched surface is engaged with a first releasing latch. It is unnecessary to wait for engagement between the first releasing latch and the guide after the circuit is closed for opening the switchgear, and a subsequent opening can be immediately started. Therefore, it is possible to reduce the time from the closing of a make break contact to starting of the next opening.
