Five, embodiment
Understand the utility model for clearer, the embodiment that finishes below in conjunction with accompanying drawing and inventor and the operating principle of permanent magnet mechanism thereof are described in further detail the utility model.
Embodiment 1:
Referring to Fig. 1, Fig. 1 is first kind of structural representation of the present utility model.
According to the technical solution of the utility model, this permanent magnet mechanism, comprise: a drive link 7, drive link is provided with an armature 12, be respectively arranged with switching winding, permanent magnet 9, pole shoe 10, closing coil 2 and fixed core 3 around the armature 12, Lower shaft sleeve 11,6 on two ends are passed through up and down at drive link 7, upper and lower axle sleeve correspondence respectively is embedded on upper end cover 1 and the bottom end cover 5, one auxiliary spacer 8 is housed on the bottom end cover 5, upper end cover 1 is a bathtub construction, and the basin inner bevel is identical with the angle of taper of armature 12.
Embodiment 2:
Fig. 2 is second kind of structural representation of the present utility model.Different is that present embodiment adopts cube structure for present embodiment and embodiment 1.End cap 1,5 and attached basin shape, fixed core 3 and pole shoe 10 are made into an integral body about inciting somebody to action in cube structure, and are generically and collectively referred to as fixed core.Simultaneously, auxiliary spacer 8, armature 12 are also made corresponding square shape.All the other are with embodiment 1.
Embodiment 3:
Fig. 3 is the third structural representation of the present utility model, different is for present embodiment and embodiment 1, has removed switching winding around armature 12, and all the other are with embodiment 1, only rely on to pass to the electric current opposite in the closing coil 2, finish sub-switching operation with the switching current direction.But this structure can produce certain demagnetizing effect to permanent magnet, under some less demanding condition, also can reach the purpose of embodiment 1.
Embodiment 4:
Fig. 4 is the 4th a kind of structural representation of the present utility model, different is for present embodiment and embodiment 3, present embodiment adopts cube structure, end cap 1,5 and attached basin shape, fixed core 3 and pole shoe 10 can be made into an integral body about inciting somebody to action in cube structure, and it is surplus with embodiment 3 to be generically and collectively referred to as fixed core, simultaneously, auxiliary spacer 8, armature 12 are also made corresponding square shape.Also can reach the purpose of embodiment 3.
Operating principle of the present utility model is summarized as follows:
In the position shown in the figure 1, be in the situation of separating brake position, making current in closing coil 2, the charged generation of coil magnetic field corresponding to switch.The stationary magnetic field that this magnetic field produces original permanent magnet in the air gap of reinforcing mechanisms top.Simultaneously, also weakened the magnetic field of 5 of armature 12 and bottom end covers.When the magnetic field in the armature 12 top air gaps increased to certain value, armature 12 began to move upward.When armature 12 taperings entered in the basin of upper end cover 1, its pull characteristics were compensated, and had avoided the defective of closing a floodgate and can't put in place.Because closing position will overcome the gravity of switch contact spring pressure and drive link 7 etc.So upper end cover 1 selects thicklyer.
When in switching winding, passing to suitable electric current, just in time opposite with above-mentioned making process.Armature 12 will move downward.Additional force when not having above-mentioned closing position because of the separating brake position is so bottom end cover 5 selects thinlyyer.
Be unkitted in the permanent magnet mechanism of switching winding at some, rely on and pass to the electric current opposite in the closing coil, finish sub-switching operation with the switching current direction.This structure can produce certain demagnetizing effect to permanent magnet.
No matter be in combined floodgate (armature is in top), or separating brake (armature is in the bottom) position, armature (being rigidly connected with drive link) all is to keep its position by the magnetic force that permanent magnet 9 produces, this just removed from failure rate higher take off the snap close mechanical device.
The utility model has then been taked Electromagnetically-operating, the brand-new design theory that permanent magnetism keeps.Make mechanism very simple, moving part seldom, failure rate is extremely low.Especially adopt benzvalene form end iron and taper armature, improved the pull characteristics of mechanism greatly.This makes that adjust improper and occurrent combined floodgate incomplete phenomena because of permanent magnet mechanism is eradicated in the past.The utility model has fundamentally solved all kinds of defectives that existing other operating mechanism exists, and has also improved the various deficiencies of common permanent magnet mechanism.The utility model can be widely used in the mesolow field of switches, and also there is certain inspiration directive function in the high-voltage switch gear field with long stroke.Because production of the present utility model does not need very complicated technology and special material, can produce in enormous quantities at an easy rate.
