Abstract
The utility model relates to a low-voltage intelligent universal circuit breaker, which is characterized in that the circuit breaker comprises a connecting rod and a close button of a circuit breaker mechanical operation mechanism, and a boss is arranged at one end of the connecting rod, which is inserted into the close button between two position limiting baffle plates for limiting the position of the connecting rod. The connecting rod of the circuit breaker mechanical operation mechanism is improved on the basis of the original design in a manner that the boss is arranged at one end thereof, which is inserted into the close button between the two position limiting baffle plates for limiting the position of the connecting rod, so that when the circuit breaker mechanical operation mechanism releases energy, the connecting rod moving downward can still be blocked between the position limiting baffle plates of the fitting piece close button by the height of the boss, instead of being detached from the position limiting baffle plates of the close button. Thus, the operation mechanism can be reliably operated, so as to ensure the switching on/off reliability of the circuit breaker, improve the product quality and reduce the maintenance expense and the cost.
Description
Technical field
The utility model belongs to a kind of low-voltage circuit breaker, particularly relates to a kind of low-tension intelligent type omnipotent breaker.
Background technology
The hidden danger of after making the mechanism action close circuit breaker, deviating from location notch easily at the connecting rod of present known low-tension intelligent type omnipotent breaker ubiquity mechanical operating mechanism with the electromagnet energising, therefore after causing circuit breaker to disconnect, mechanism can not release and can make breaker closing when closure occurring again, thereby causes the operation of circuit breaker on/off switch to have insecure problem.
Summary of the invention
The utility model provides a kind of low-tension intelligent type omnipotent breaker that can reliably carry out the on/off switch operation after the circuit breaker disconnection that makes for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it includes the connecting rod and the close push button of breaker mechanical operating mechanism, and described connecting rod has a boss at that end that it inserts between close push button two postive stop baffles spacing to described connecting rod.
Advantage and the good effect that the utlity model has are: owing to adopted in the former design of the connecting rod of breaker mechanical operating mechanism that end between close push button two postive stop baffles spacing to connecting rod to increase the modified model connecting rod of boss, when circuit breaker operation mechanism is released energy, connecting rod moves down the height that utilizes boss and still can be blocked between the postive stop baffle of counterpart close push button, makes connecting rod can't deviate from the postive stop baffle of close push button.Make the operating mechanism reliable in action like this, thereby guaranteed the reliability of circuit breaker on/off switch, improved product quality and also reduced maintenance cost simultaneously, reduced cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of connecting rod among Fig. 1;
Fig. 3 is the position view of close push button in circuit breaker operation mechanism;
Fig. 4 is the A-A cutaway view of Fig. 3.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, 2, the end of connecting rod 3 between two postive stop baffles 4 of close push button 2 has a boss 5.
Shown in Fig. 3,4, connecting rod 3 and be mated the upper right quarter that part closing electromagnets 1, close push button 2 all are positioned at mechanical operating mechanism, close push button 2 forwardly, connecting rod 3 in close push button 2 back and its front end stretch in the middle of 2 liang of postive stop baffles of close push button 4.Closing electromagnets 1 is positioned at the top of connecting rod 3 front ends.
Mechanical operating mechanism is when energy storage not (circuit breaker open position), and connecting rod 3 is in Fig. 4 picture displayed (gapped) between the two with close push button 2; After mechanism's energy storage puts in place, connecting rod rotates up and moves the postive stop baffle front end triangle place by close push button 2, connecting rod 3 was moved in the action downwards of (breaker closing) electromagnet energising push rod when energy was released by mechanism, because electromagnet energising actuating length is bigger than the stroke that manual closing button 2 promotes, connecting rod 3 as might deviate from from the postive stop baffle front end triangle lower end of close push button 2 when moving down by former design, improve back link and utilize the height of boss to be blocked on the postive stop baffle sidewall of close push button 2, make connecting rod can't deviate from the stopper slot of close push button.Make the operating mechanism reliable in action like this, thereby guaranteed the reliability of circuit breaker on/off switch.
Claims (1)
