Embodiment
As shown in Figure 1, the present invention is by switch pedestal 1, A permanent-magnet manipulating mechanism 2, B permanent-magnet manipulating mechanism 3, A vacuum interrupter 4, B vacuum interrupter 5, C vacuum interrupter 6, D vacuum interrupter 7, A connecting lever 8, B connecting lever 9 and intelligent controller 10 form, and A permanent-magnet manipulating mechanism 2 and B permanent-magnet manipulating mechanism 3 are respectively by support installing in switch pedestal 1, and A permanent-magnet manipulating mechanism 2 and B permanent-magnet manipulating mechanism 3 are controlled by PLC, A vacuum interrupter 4, B vacuum interrupter 5, C vacuum interrupter 6 and D vacuum interrupter 7 respectively by support installing in switch pedestal 1, A connecting lever 8 and B connecting lever 9 are movably arranged in switch pedestal 1 respectively, A permanent-magnet manipulating mechanism 2 is connected with the upper end transmission of B connecting lever 9 with A connecting lever 8 respectively with drive rod one end of B permanent-magnet manipulating mechanism 3, the upper end of A connecting lever 8 and B connecting lever 9 side is movably connected with the moved end of B vacuum interrupter 5 and D vacuum interrupter 7 respectively, the lower end of A connecting lever 8 and B connecting lever 9 side is movably connected with the moved end of A vacuum interrupter 4 and C vacuum interrupter 6 respectively, A vacuum interrupter 4, B vacuum interrupter 5, the quiet end of C vacuum interrupter 6 and D vacuum interrupter 7 meets A successively, B, the input of C three-phase and the output of common port D, A vacuum interrupter 4, B vacuum interrupter 5, the moved end of C vacuum interrupter 6 and D vacuum interrupter 7 meets A successively, B, C three-phase output and the input of common port D, A, the output of B phase is in parallel with D vacuum interrupter 7 moved end of common port D respectively by busbar, and the output of common port D is connected in series with C vacuum interrupter 6 moved end of C phase by busbar.
Operation principle: when permanent-magnet manipulating mechanism (A permanent-magnet manipulating mechanism 2 and B permanent-magnet manipulating mechanism 3) receives the instruction that intelligent controller 10 sends, when doing forward and backward motion, connecting lever (A connecting lever 8 and B connecting lever 9) is driven also to do forward and backward motion, two arc control device do respectively and close componental movement (i.e. A vacuum interrupter 4, B vacuum interrupter 5 and C vacuum interrupter 6, D vacuum interrupter 7,), mutually form interlocking.
Switch has two connecting lever unit groups, and namely A vacuum interrupter 4, B vacuum interrupter 5 and A connecting lever 8 is one group, and C vacuum interrupter 6, D vacuum interrupter 7 and B connecting lever 9 is one group.
Embodiment 1: when the action of B permanent-magnet manipulating mechanism 3 push-and-pull B connecting lever 9, when D vacuum interrupter 7 closes, then C vacuum interrupter 6 is for dividing; And simultaneously A permanent-magnet manipulating mechanism 2 push-and-pull A connecting lever 8 action, when A vacuum interrupter 4 close, B vacuum interrupter 5 points, A phase and the conducting of common port D output will be gone into, then export A phase;
Embodiment 2: if B vacuum extinction 5 is closed, A vacuum interrupter 4 timesharing, will form B phase and the conducting of common port D output, then export B phase;
Embodiment 3: when C vacuum interrupter 6 close, D vacuum interrupter 7 timesharing of common port D, A vacuum interrupter 4 and B vacuum interrupter 5 are shielded by the disconnection of common port D, only export C phase.
Permanent-magnetic switching uses connecting lever motion principle to achieve mechanical interlocked, avoids the phenomenon that two-phase exports altogether; Reach three and enter an object out.This permanent-magnetic switching refer to the theory of energy-conserving and environment-protective, and use the action of permanent magnet mechanism interior loop instantaneous large-current traction connecting lever, when exporting mutually arbitrarily, utilize the permanent magnetic of idle to maintain, greatly save energy resource consumption, integrate with world's environmental protection new ideas.The utilization of vacuum interrupter, be then under the state making switch be in vacuum, substantially prolongs the useful life of switch, ensure that stability and the fail safe of switch.And the control system of permanent-magnetic switching adopts Based Intelligent Control theory, by optocoupler monitoring display on off state, then send next step action command through the integrated circuit intelligence of programming and carry out required any phase commutation.
