Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
The contrast accompanying drawing, present embodiment is a three-phase Outdoor Permanent Magnet Mechanism Vacuum Circuit Breaker, insulating protective layer adopts upper and lower pole form of tubes, and its arc control device 2, insulated tension pole 4 etc. are sealed in by in last pole pipe 19, the following pole pipe 22 formed enclosure spaces, have formed a pole jointly.The upper end of support 12 is connected with the lower end of insulated tension pole 4, and the body of support 12 places in the base 11, and its downside is provided with a guide rail 9, and pin 5 places in the guide groove of this guide rail 9, can be along the upper and lower slip of its guide groove.Pin 5 is hinged with an end of slide plate 8, the other end of slide plate 8 respectively with motion main shaft 6 at interval uniform three point articulated, wherein a pin joint is hinged with slide plate 8 again after the passing of motion main shaft 6, the part of motion main shaft 6 in machine barrel combination 7 adopts with the interlocking of axle key formula with armature 20, and can be along being moved axially in the 13 formed cylindrical spaces by coil 16, magnet ring with motion main shaft 6.
Shown in the drawings is that mechanism is in the separating brake position, and no current passes through in the coil 11 at this moment, and armature 20 is subjected to bigger static confining force under the effect in the magnetic field of permanent magnet 13, and makes the more stable separated position of maintenance between moving contact 3 and the fixed contact 21.
When mechanism need close a floodgate, the electric current of coil 16 logical certain orientations, the coil 16 of energising can produce magnetic field, therefore, armature is subjected to the action of a magnetic field that closes of coil current and permanent magnet generation, at this moment, armature 20 is subjected to the magnetic field force that closes to the right, under the effect of this power, the motion main shaft 6 that armature 20 drives are fixed together is to left movement, the slide plate 8 hinged with motion main shaft 6 moves to left with motion main shaft 6 on one side, around pin joint rotate on one side, make hinged and place the pin in the guide rail 9 to move up with slide plate 8, promoting support 12 moves upward, and drive connected insulated tension pole 14 and move upward, three-phase contact (moving contact 3) moves upward synchronously, up to moving, till fixed contact closes, realize closing a floodgate, and under the magnetic field force effect of permanent magnet 13, remain on closing position, and tripping spring 10 is stretched, laid in the potential energy of return.In order to close a floodgate better, be close to that the front end housing 17 usefulness permeability magnetic materials of coil one side make, coil and permanent magnet produce magnetic loop during combined floodgate, and the rear end cap 18 of opposite side is just with being nylon material, disconnect the magnetic loop of permanent magnet during combined floodgate, make armature 20 be subjected to bigger to the right close magnetic field force.
When mechanism needs separating brake, coil 11 is connected with rightabout electric current, the magnetic field that coil 11 is produced on armature 20 bottom air gaps is opposite with the magnetic direction that permanent magnet produces, to offset suffered electromagnetic attraction left unshakable in one's determination, this moment, armature 20 will move to right motion main shaft 5 under the return potential energy effect of tripping spring 10, and drive supports 12 by slide plate 8, guide rail 3 and pin 5 and move downward, the moving contact 3 that is attached thereto is separated with fixed contact, realize separating brake.
