Abstract
The utility model relates to the technical field of vacuum circuit breakers, in particular to an emergency opening device of a permanent magnetic circuit breaker, which comprises a press button, a reset pressure spring, a connecting rod, a connection plate and a crank arm, wherein the connecting rod passes through a support block fixed on the crank arm, the connecting rod and the support block are in clearance fit with each other, the press button is fixed at one end of the connecting rod, the reset pressure spring is arranged between the press button and the connecting rod, the other end of the connecting rod is connected with the connection plate through a pin, the connection plate is fixed on a shaft, the crank arm is welded on the shaft, the protruding part of the crank arm is butted against the bottom of the cover plate, the cover plate is connected with a movable iron core in a permanent magnet. The emergency opening device provided by the utility model has a simple structure, is convenient to operate and has reduced cost.
Description
Technical field
The utility model relates to the vacuum circuit-breaker technical field, especially the urgent switching-off device of permanent-magnet breaker.
Background technology
Urgent switching-off device is the device that in emergency circuit breaker is carried out sub-switching operation on the vacuum circuit-breaker panel for the operator, the requirement separating brake is rapid, easy to operate present, the urgent switching-off device of permanent-magnet breaker generally is to be realized by the cam rotation, also need join special-purpose operating grip, this structure is cumbersome, troublesome poeration, and impracticable.
The utility model content
The utility model is to provide a kind of simple in structure, easy to operate, the urgent switching-off device of lower-cost permanent-magnet breaker.
The technical scheme that its technical problem that solves the utility model adopts is: the urgent switching-off device of permanent-magnet breaker, form by button, reseting pressuring spring, connecting rod, connecting plate, connecting lever etc., connecting rod passes back-up block fixing on the bent plate, and both matched in clearance, and connecting rod one end is fixed with button, between be provided with reseting pressuring spring, the other end be connected with connecting plate by pin, connecting plate is fixed on the axle, the axle on be welded with connecting lever, connecting lever protrusion place be against cover plate below, cover plate links to each other with moving iron core in the permanent magnet.
Described connecting lever is bilateral connecting lever.
When circuit breaker is in closing position, press button, connecting rod promotes connecting plate, drive axle and go up connecting lever and rotate, thereby jack-up cover plate upwards makes in the permanent magnet the upwards action of taking advantage of a situation of moving iron core thread off, i.e. breaker open operation;
Because the effect of reseting pressuring spring, connecting plate automatically replies, and connecting lever still remains on original position, does not influence on/off switch again.
The beneficial effects of the utility model are: the urgent switching-off device of the utility model permanent-magnet breaker is simple in structure, easy to operate, and cost is lower.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is Fig. 1 right view.
Among Fig. 1: 1. spool, 2. cover plate, 3. connecting lever, 4. connecting plate, 5. permanent magnet, 6. connecting rod, 7. pin, 8. bent plate, 9. reseting pressuring spring, 10. button, 11. buttons.
Embodiment
The urgent switching-off device of permanent-magnet breaker, form by button 10, reseting pressuring spring 9, connecting rod 6, connecting plate 4, connecting lever 3 etc., connecting rod 4 passes back-up block 9 fixing on the bent plate 8, and both matched in clearance, and connecting rod 6 one ends are fixed with button 11, between be provided with reseting pressuring spring 10, the other end be connected with connecting plate 4 by pin 7, connecting plate 4 is fixed on the axle 1, axle is welded with connecting lever 3 on 1, connecting lever 3 protrusion places be against cover plate 2 belows, cover plate 2 links to each other with moving iron core in the permanent magnet 5.
Described connecting lever 3 is bilateral connecting lever.
When circuit breaker is in closing position, press button 11, connecting rod 6 promotes connecting plate 4, and connecting lever 3 rotates on the drive axle 1, thereby makes progress jack-up cover plate 2, makes 5 li moving iron cores of permanent magnet take advantage of a situation upwards to move and threads off, be i.e. breaker open operation;
Because the effect of reseting pressuring spring 10, connecting plate 4 automatically replies, and connecting lever 3 still remains on original position, does not influence on/off switch again.
