Discharge loop 62,63 connects switching winding 31 and closing coil 32 respectively.
During the utility model work, if photoelectric sensor 39 sends the signal of separating brake position when initial, the intelligence pulse power 6 just can be ordered 32 discharges of the 63 pairs of closing coils in high-frequency discharge loop at any time as required, produce high-frequency pulse current and magnetic field, at this moment, the halted state that repulsion dish 37 also is in separating brake work (promptly as shown in Figure 2, upper end at closing coil 32), therefore under the effect of pulsed magnetic field, the repulsion dish 37 that is in closing coil 32 upper ends will induce eddy current fast, eddy current produces electric power under the effect in magnetic field, move upward thereby drive repulsion bar 37, for combined floodgate provides actuating force.Combined floodgate buffer gear 5 is under repulsion bar 37 drives, underframe 52 and buffer oil cylinder 56 move upward together, compressing spring 53 drive upper frames 51 simultaneously moves upward, in buffer oil cylinder 56 moves upward process, when piston rod 510 is run into limiting plate 58, stop motion, and buffer oil cylinder 56 is still moving upward at this moment, so liquid in the piston rod 510 meeting compression cylinders, produce cushioning effect, absorption portion kinetic energy, at this moment, moving upward of upper frame 51 makes the static contact head device of moving contact and its top realize steadily closing a floodgate, upper frame 51 stop motions after closing a floodgate, and underframe 52 still moves upward continuing, and compression spring 53 is therefore for moving, the reliable contact of fixed contact provides confining force.Meanwhile, combination dish spring confining force mechanism 4 is under repulsion bar 37 drives, and along with moving upward of confining force bar 21, what make combination dish spring still can provide lasting closing retention force with joint efforts after combined floodgate puts in place.After repulsion bar 37 moved upward, shadow shield 38 will break away from photoelectric sensor 39 and no longer shading, and photoelectric sensor 39 also just no longer sends the separating brake position signalling, and the intelligent pulse power 6 just can stop the order of closing a floodgate.
