In other words, in the shown circuit-breaker of Fig. 4, make when flowing through excessive electric current in the main circuit action of not tripping as circuit breaker just in case break down, fusion causes the generation of the unusual state of affairs to main contactor because the contact resistance between the contact point generates heat.Under such contact point molten condition, even rocker handle is taked the operation of closing, main contactor also can fusion and can not open, so use common operating physical force just can not promote rocker handle.But when the combination external operation handle device carried out shutoff operation, the main contactor of circuit-breaker still kept molten condition, and the operating handle of external operation handle device but is in and shows the position that disconnects, a problem that Here it is.
In other words, in existing external operation handle device, when the driving mechanism of the rotating base of aforesaid installation crank-pin and sliding bottom combination moved as boosting device, the power that is applied on the operating handle increased, and acts on the circuit-breaker rocker handle of amplification.Thus, under the state of contact point fusion, externally apply power on the operating handle of operating grip device and when getting back to open position, the movable part of the switching mechanism that is connected with rocker handle (movable contact) is out of shape and makes operating handle turn back to the position that shows disconnection, can be as shown in FIG. 5, the spring lock 16 of being drawn by operating handle 13 is locked in jam plate on this open position.
But, though the main contactor fusion of circuit-breaker and make the electrode closure under this state, the operating handle 13 of external operation handle device shows the position (with reference to Fig. 5) that disconnects.For this reason, the maintenance personal thinks that by the disconnection that external operation handle device shows circuit-breaker has opened circuit by mistake, and therefore the danger of electric shock just arranged on the loop of the secondary side (load side) of circuit-breaker.
Therefore, in order to prevent such electric shock accidents, developed under the main contactor molten condition of circuit-breaker and carried out under the situation of opening operation, the rocker handle of circuit-breaker itself mechanically is locked in the position of connection, give the function of its isolation, can not move to open position, but such circuit-breaker, the complex structure of its switching mechanism, cost are very high.
The present invention is in view of the premises, its purpose is exactly the external operation handle device that uses in the common circuit-breaker of being assembled in of isolation features for not having, a kind of external operation handle device of giving isolation features is provided, under the abnormality of the main contactor fusion of circuit-breaker, operating handle can not be got back to open position and improve fail safe.
Summary of the invention
In order to realize above-mentioned purpose, according to the present invention, this device can be outside coiling to the circuit-breaker that is provided in the band rocker handle in the dish connect, opening operation, this handle apparatus by with the body that combines of circuit-breaker own; The rotary operating handle that is provided with previously at this body; And will make up with the rotating base and the sliding bottom of crank-pin, be that the assembly of straight-line driving mechanism constitutes with the rotational transform of operating handle, described sliding bottom hung mutually with the rocker handle of circuit-breaker close, drive rocker handle to the position of connecting, disconnecting
In described driving mechanism, be provided with Lock Part, it is locked hand under the abnormality of the main contactor generation fusion of circuit-breaker, makes it can not shift to open position.
(1) as Lock Part, be provided with on the sliding bottom of driving mechanism, disconnect the securing rod that stands facing each other on the direction with the crank-pin of rotating base, and this securing rod pressed to entopic back-moving spring, simultaneously also be provided with stop in base side, can utilize the opening operation that is in the handle under the molten condition at the contact point of circuit-breaker, the described securing rod extension that tilts with resisting with back-moving spring closes and stops sliding bar to disconnecting moving of direction.
(2) in preceding paragraph (1), on the sliding bottom of driving mechanism, be provided with the push mechanism that stands facing each other mutually at the rocker handle of connecting side and circuit-breaker discretely with its base body, this push mechanism is connected with the base body by spring.
In said structure, if the elastic force of the back-moving spring of the securing rod on sliding bottom (compression spring), be set at the operating physical force that when the common switch motion of circuit-breaker, is applied on the rocker handle and do not make spring bending, when the operating handle that external operation handle device under the normal condition of fusion does not take place when the main contactor at circuit-breaker carries out opening operation, rocker handle with regard to the drive circuit circuit breaker, securing rod is remained on the original normal position, and the crank-pin of rotating base is pressed to the disconnection direction to sliding bottom with securing rod.
And be under the abnormality of fusion at the main contactor of circuit-breaker, hang mutually on the sliding bottom that closes with rocker handle, on this position, added very big restraining force.Under this state, for circuit-breaker is carried out opening operation, get back to when disconnecting direction and externally apply on the operating handle of operating grip device than bigger power usually, be forced into the securing rod antagonism back-moving spring on the crank-pin of rotating base and rotate.Simultaneously, when being pressed in push mechanism, the sliding bottom that is subjected to operating physical force makes on the rocker handle when connecting spring and keep crooked, also take place when a bit mobile to disconnecting direction with securing rod, then the securing rod that rotates as mentioned above just be arranged on body on stop contact extension and closes, being moved further of prevention sliding bottom.
The result, when the operating handle of external operation handle device can not be got back to the position that show to disconnect, just can prevent from existing external operation handle device, to become under abnormality problem, be in fusion at main contactor because the lever operated misidentification that causes disconnects shows.In the case,, just can on the rocker handle of circuit-breaker, not apply excessive operating physical force, thereby just can not make the movable part distortion of circuit-breaker inside yet owing to stoped sliding bottom to move to disconnecting direction.
