Fig. 2 joins the structural representation of an embodiment of HVAC vacuum circuit breaker manual switching-off device of permanent-magnet manipulating mechanism for the utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, separating brake pad 2, take-off lever 3, bearing 4, bearing pin 5, permanent-magnet manipulating mechanism 6, mounting panel 7, action bars 8, connecting lever 9, fixed cover 10, spring 11, dwang 12, moving block 13, cam 14, operating grip
As shown in Figure 2, the utility model HVAC vacuum circuit breaker manual switching-off device is positioned at permanent-magnet manipulating mechanism 5 on mounting panel 6 bottom and top are fixed with action bars 7 and dwang 11 respectively, one end of action bars 7 and dwang 11 stretches out mounting panel 6 outsides in the same way, be fixed with connecting lever 8 and moving block 12 on action bars 7 and the dwang 11 respectively, connecting lever 8 and moving block 12 are by bearing pin 4, bearing 3 links to each other with spring 10 with fixed cover 9, dwang 11 is by cam 13 fixed thereon, bearing pin 4 links to each other with the take-off lever 2 of permanent-magnet manipulating mechanism 5 with bearing 3,3 on bearing contacts with separating brake pad 1, is fixed with operating grip 14 on the dwang 11.
When circuit breaker needs manual brake separating, operating grip 14 is applied external force, driving action bars 7 rotates, action bars 7 drives connecting levers 8 and rotates, by bearing pin 4, bearing 3 and fixed cover 9 compression springs 10 storage power, when enough greatly time of the store energy of spring 10, it will drive moving block 12 by fixed cover 9, bearing 3 and bearing pin 4 and rotate, drive cam 13 simultaneously and rotate, drive take-off lever 2 by cam 13 by bearing pin 4, bearing 3 and separating brake pad 1 and move up, realize breaker open operation.
In the separating brake process, owing to used transition member such as spring 10 and bearing 3, increased flexible transition, reduced frictional force, improved efficient.
