Embodiment
For making that architectural feature of the present utility model and the effect reached are had a better understanding and awareness, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
As shown in Figure 1, a kind of long-stroke permanent magnet breaker mechanism described in the utility model, comprise shell 5, core assembly 1 and main shaft 10, core assembly 1 is arranged in shell 5 and runs through by main shaft 10, and shell 5 inner rings are fixedly installed respectively switching winding 2, permanent magnet 3 and closing coil 4 from top to bottom.Shell 5 is cylindrical, is looped around outside core assembly 1, and switching winding 2, permanent magnet 3 and the setting of closing coil 4 in shell 5, be equally also looped around outside core assembly 1.Main shaft 10 runs through core assembly 1 and shell 5, thereby both are fixing in the horizontal direction, only with movable in vertical direction.As shown in Figure 2, core assembly 1 comprise separating brake float pin 16, close a floodgate float pin 18, iron core 11, be arranged on the upper cover 12 on iron core 11 tops and be arranged on the lower cover 14 of iron core 11 bottoms, upper cover 12 and lower cover 14 can adopt various ways fixed installation with the installation of iron core 11 upper and lowers, while meeting work not because magnetic force comes off.The unsteady pin of separating brake 16 top movable are installed in upper cover 12, and separating brake floats pin 16 bottoms by tripping spring 17 connection iron core 11 tops.The separating brake pin 16 that floats is arranged on that upper cover 12 is interior can move up and down by tripping spring 17, and separating brake pin 16 tops of floating can be fastened in upper cover 12 by track, also can be fixed in upper cover 12 by miscellaneous part.Separating brake floats and sells 16 bottom installation tripping spring 17, and contacts with the top of iron core 11 by tripping spring 17, and tripping spring 17 can float and produce spring force between pin 16 and the top of iron core 11 separating brake.Unsteady 18 bottoms of selling of combined floodgate are movably installed in lower cover 14, and switching-in spring 19 connection iron core 11 bottoms are passed through on unsteady 18 tops of selling of closing a floodgate.The pin 18 that close a floodgate to float can move up and down by switching-in spring 19 lower cover 14 is interior, and pin 18 bottoms of floating of closing a floodgate equally also can be fastened in lower cover 14 by track, also can be fixed in lower cover 14 by miscellaneous part.Closing a floodgate floats sells 18 top installation switching-in spring 19, and contacts with the bottom of iron core 11 by switching-in spring 19, and switching-in spring 19 can float and produce spring force between pin 18 and the bottom of iron core 11 closing a floodgate equally.
In order to guarantee better result of use, can also comprise screwing 13 and lower screw 15.Upper cover 12 is fixedly mounted on iron core 11 tops by screwing 13, has better guaranteed in carrying out magnetic force process, can not come off between upper cover 12 and iron core 11 tops.Lower cover 14 is fixedly mounted on iron core 11 bottoms by lower screw 15, has better guaranteed in carrying out magnetic force process, can not come off between lower cover 14 and iron core 11 bottoms.Iron core 11 can be selected soft magnetic material, and soft magnetic material has the magnetic material of low-coercivity and high magnetic permeability.Soft magnetic material is easy to magnetization, is also easy to demagnetization.Main shaft 10 can be selected stainless steel material, and the existing rustless property of stainless steel material, has again acid resistance and corrosion resistance, and dependability is higher.
During actual use, when permanent-magnet breaker will carry out sub-switching operation, before permanent-magnet breaker separating brake, the magnetic field force that the magnetic circuit that the lower surface of iron core 11 is formed by permanent magnet 3, closing coil 4 and shell 5 produces holds.During separating brake, switching winding 2 electric generation magnetic field, make the upper surface of iron core 11 be subject to the effect of magnetic field force, because air gap is larger, magnetic field force is by concentrating on the unsteady pin of separating brake 16 end faces that ejected by tripping spring 17, and along with magnetization energy increases, the unsteady pin 16 drive iron cores 3 of separating brake move together.Before movement travel finishes, first by the unsteady pin 16 of separating brake, touch shell 5, now air gap is less, and iron core 11 just pushes tripping spring 17 and is squeezed in upper cover 12 together with the unsteady pin 16 of separating brake under the effect of suction.So just, completed the whole movement travel of separating brake.In like manner, when permanent-magnet breaker will carry out closing operation, before permanent-magnet breaker closes a floodgate, the magnetic field force that the magnetic circuit that the upper surface of iron core 11 is formed by permanent magnet 3, switching winding 2 and shell 5 produces holds.During combined floodgate, closing coil 4 electric generation magnetic field, make the lower surface of iron core 11 be subject to the effect of magnetic field force.Because air gap is larger, magnetic field force is by concentrating on unsteady 18 end faces of selling of the combined floodgate being ejected by switching-in spring 19 equally, and along with magnetization energy increases, the unsteady 18 drive iron cores 3 of selling that close a floodgate move together.Before movement travel finishes, the pin 18 that first floats by closing a floodgate touches shell 5, and now air gap is less, and iron core 11 just pushes switching-in spring 19 and is squeezed in lower cover 14 together with the unsteady pin 18 that closes a floodgate under the effect of suction.So just, completed the whole movement travel of closing a floodgate.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
