Embodiment
See also its implementation process of description of drawings:
A kind of indoor AC high voltage vacuum breaker comprises casing, and the middle part in the casing is provided with permanent magnet mechanism 1, and permanent magnet mechanism 1 is permanent-magnet manipulating mechanism just, drives the motion of pull bar by coil electricity.Permanent magnet mechanism 1 is connected with output connecting plate 19 by connecting rod 14, little connecting plate 18, and connecting rod 14, little connecting plate 18, output connecting plate 19 connect by connecting bearing pin 17 successively, and permanent magnet mechanism 1 is installed in the casing by mounting panel 5.The side of permanent magnet mechanism 1 also is provided with two electric capacity 13 in the casing, the both sides of permanent magnet mechanism 1 are respectively arranged with opening button 4 and switch knob 11, opening button 4 links to each other with transmission mechanism by spring respectively with switch knob 11, also is provided with capacitance charging module 10, transition wiring board 2, power supply indicator 5, divide-shut brake indication 12, permanent magnetism controller 3, counter 7, auxiliary switch 8, closing by hand connecting lever 9 in the casing.Urgent separating brake axle 12 is fixedly connected on the permanent magnet mechanism 1, and the position near permanent magnet mechanism 1 on the urgent separating brake axle 12 is provided with eccentric shaft, and when eccentric shaft rotated to an angle, eccentric shaft was touched mutually with the cover plate 131 of permanent magnet mechanism 1.In case of emergency, rotate the separating brake handle, urgent separating brake axle 12 drives eccentric shaft and rotates under the rotation of separating brake handle, and eccentric shaft drives the manual brake separating roller again.The powerful separating brake switch that promotes of manual brake separating roller forces breaker open operation under the effect of external force.At this moment, the external force effect has exceeded the sphere of action of magnetic force greater than the magnetic force of permanent-magnet manipulating mechanism, so make breaker open operation by force.The structure of described permanent magnet mechanism 1 is, be provided with moving iron core 133, inner yoke 135, switching winding 137, magnet 134, magnetostatic core 9, closing coil 136 in the cavity that two cover plates 131 and outer yoke 138 constitute, connecting rod 14 is fixedly connected on the moving iron core 133, and manual brake separating bar 132 is fixed on the permanent magnet mechanism 1.After the closing coil energising, closing coil produces magnetic field moving iron core is inhaled, and simultaneously, under the effect of inner yoke and magnet, makes iron core keep this state.When needing separating brake, to the switching winding energising, switching winding produces an opposing magnetic field, and iron core is risen.During use, after permanent magnet mechanism 1 energising, moving iron core 133 actions of permanent magnet mechanism drive connecting rod 14 motions, through main output toggle arm 16, driving little connecting plate 18 moves upward around certain angle main output toggle arm 16 that links, thereby realize that insulated tension pole moves up and down, realize the divide-shut brake action of circuit breaker.
Those skilled in the art's simple replacement and change all are within the protection range of this patent in this area.
