Description
Technical field
The utility model relates to a kind of field of circuit breakers, refers more particularly to a kind of novel breaker kinematic link mechanism.
Background technology
At present, in the structure of small circuit breaker mechanism, skid off from the lever inclined-plane and realize that there are wild effects such as the dispersed big and slide fastener of tripping force in free tripping mechanism by connecting rod, its reason is a structures shape.Connecting rod skids off from the lever inclined-plane quadric chain is become the structure of five-bar mechanism, owing to there is not a snap close, this requires the resistance to wear etc. of accuracy, processing technology and material of tripping part size very high.Because the restriction of domestic material and level of processing, be difficult to all to accomplish in all its bearings very perfect, therefore causing mechanism to exist tripping force to disperse must be greatly and wild effect such as slide fastener.Traditional breaker closing process is slow, can't realize that encouraging coil by public affairs closes a floodgate.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of simple in structure, easy and simple to handle realization singly to close or the reclosing function single the branch, the transmission accuracy height has the novel circuit breaker kinematic link mechanism of disjunction short circuit current ability.
The utility model is realized in the following way:
A kind of novel breaker kinematic link mechanism is characterized in that: mainly include cam (51), roller connecting lever (52), output toggle arm (53), yielding rubber (54), connecting rod (55), connecting lever (56), pull bar (57), spring base (58), tripping spring (59); Wherein: cam (51) is located at roller connecting lever (52) top, output toggle arm (53) links to each other with roller connecting lever (52) and connecting rod (55) respectively, connecting lever (56) links to each other with connecting rod (55) and pull bar (57) respectively, connecting rod (55) one ends are provided with yielding rubber (54), and the other end is provided with spring base (58) and tripping spring (59).
Described pull bar (57) is formed by three, start simultaneously.
Described connecting lever (56) is formed by three, start simultaneously.
Its course of work: after the switching-in spring energy storage, after hand push button shake-up and the action of shunt opening coil electricity, drive the rotation of combined floodgate semiaxis, switching-in spring is released can, circuit breaker kinematic link mechanism promotes vacuum interrupter by elements such as cam, sincere son, output toggle arm, connecting rod, insulated tension poles and closes a floodgate, and makes the tripping spring energy storage simultaneously; Separating brake drives the rotation of separating brake semiaxis by touching opening button or shunt opening coil (overcurrent coil) energising action, and tripping spring is released pulling such as the actuated element that can pass through sincere son, connecting rod, insulating bar vacuum interrupter separating brake.Combined electrical apparatus can also pass through fusing, makes the on-load switch separating brake by trip assembley therefor.
In sum, simple in structure, the easy and simple to handle realization of the utility model singly closed or the reclosing function single the branch, the transmission accuracy height, and it is a kind of desirable novel circuit breaker kinematic link mechanism that disjunction short circuit current ability is arranged.

Embodiment
Now in conjunction with the accompanying drawings, the utility model embodiment is described in detail in detail:
As shown in Figure 1, the utility model mainly includes cam (51), roller connecting lever (52), output toggle arm (53), yielding rubber (54), connecting rod (55), connecting lever (56), pull bar (57), spring base (58), tripping spring (59); Wherein: cam (51) is located at roller connecting lever (52) top, output toggle arm (53) links to each other with roller connecting lever (52) and connecting rod (55) respectively, connecting lever (56) links to each other with connecting rod (55) and pull bar (57) respectively, connecting rod (55) one ends are provided with yielding rubber (54), and the other end is provided with spring base (58) and tripping spring (59).Described pull bar (57) is formed by three, start simultaneously.Described connecting lever (56) is formed by three, start simultaneously.
Operation principle: after on-load switch is received reclosing command, the trip gear part is removed the energy storage hold mode, and cam (51) rotates and drives roller connecting lever (52) rotation, promotes 3 pull bars (57) that connect separately to pressing down, spring base (58) promotes tripping spring (59) compression, finishes combined floodgate.
After on-load switch is received the separating brake instruction, the tripping spring (59) of circuit breaker kinematic link mechanism unclamps, the "on" position of on-load switch and circuit breaker kinematic link mechanism is removed, the separating brake load that is added in the circuit breaker kinematic link mechanism loses support, promote circuit breaker kinematic link mechanism kinematic parts and do sub-switching operation, spring base (58) promotes connecting rod (55) three connecting levers (56) rotation simultaneously, after drawing high the buffering of pull bar (57) through yielding rubber (54), active force reduces, output toggle arm (53) promotes roller connecting lever (52) and rotates, and related cam (51) changes certain angle automatically and finishes sub-switching operation.Circuit breaker kinematic link mechanism is connected with the link gear organic integration.
Its course of work: after the switching-in spring energy storage, after hand push button shake-up and the action of shunt opening coil electricity, drive the rotation of combined floodgate semiaxis, switching-in spring is released can, circuit breaker kinematic link mechanism promotes vacuum interrupter by elements such as cam, sincere son, output toggle arm, connecting rod, insulated tension poles and closes a floodgate, and makes the tripping spring energy storage simultaneously; Separating brake drives the rotation of separating brake semiaxis by touching opening button or shunt opening coil (overcurrent coil) energising action, and tripping spring is released pulling such as the actuated element that can pass through sincere son, connecting rod, insulating bar vacuum interrupter separating brake.Combined electrical apparatus can also pass through fusing, makes the on-load switch separating brake by trip assembley therefor.
