Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art without creative labor it is obtained it is all its
His embodiment, shall fall within the protection scope of the present invention.
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be further explained below with reference to the attached drawings and specific examples, but not as the limitation of the invention.
Specific embodiment 1: illustrating present embodiment, a kind of torsion described in present embodiment referring to figs. 1 to Fig. 4
Turning damp type electromagnetism anti-dance device includes two conductor discs and permanent magnetic disk；
The permanent magnetic disk is located between two conductor discs, and is connected between conductor disc and permanent magnetic disk by connector, makes to lead
Body disc is free to relatively rotate with permanent magnetic disk；
Permanent magnetic disk includes support frame and several permanent magnets, and permanent magnet is circumferentially evenly arranged on the support frame, permanent magnet edge
Axial charging, and the pole N-S is alternately arranged.
When in use, conductor disc 1 is fixed on conductor spacer 5 for above-mentioned electromagnetism anti-dance device.As shown in Figure 1, the interval in Fig. 1
Stick 5 is quadripartion conductor spacer, which arranges that a conductor disc 1 of anti-dance device is fixed on conductor spacer 5 on the transmission line
On, and it is located at the lower part of conductor spacer 5.
