Electrical current size i.e. can reach the magnetic flux density mated with permanent magnet.
Below technology to be protected is described in detail:
Halbach array has extremely strong poly-magnetic energy power, is up to now can be by minimum permanent magnet volume production
The track arrangement mode of raw high-intensity magnetic field.The high Temperature Superconducting MAGLEV system having had a lot of country at present uses
Halbach array is as the arrangement mode of its tracks of permanent magnetism.Tracks of permanent magnetism is that high temperature superconducting magnetic suspension system can not
Or the important component part lacked, the arrangement mode of the most conventional tracks of permanent magnetism mainly has Conventional monomodal type permanent magnetism
Track and Halbach type tracks of permanent magnetism, prior art is to Conventional monomodal type tracks of permanent magnetism magnetic turnout electromagnetism
Ferrum has carried out analyzing design, and Halbach can use the magnetic flux that the fewest permanent magnet consumption generation is bigger close because of it
Spend and be widely used, but there is presently no about Halbach type tracks of permanent magnetism magnetic turnout electric magnet
Design, this patent proposes the magnetic turnout Electromagnetic Design of Halbach type tracks of permanent magnetism, for after
High temperature superconducting magnetic suspension system magnetic turnout research provides important mentality of designing.
Conventional monomodal tracks of permanent magnetism the provided magnetic flux density of magnetic turnout electric magnet is less at present, causes in road
Trouble position electric magnet does not mates with the high magnetic flux density of permanent magnet, thus causes by high-temperature superconductor magnetic during track switch
Floating vehicle fluctuation of service, this utility model is made that following being correspondingly improved with regard to this shortcoming, in order to improve
Magnetic flux density produced by electric magnet.
Magnetic turnout electric magnet, as it is shown in figure 1, comprising: iron core 1 and coil, iron core comprises four
Branch, four branches are arranged side by side the most successively, and one end of the same side is collected and is integrated, two kept left
The other end of individual branch extends magnetic pole A after collecting, the other end of the Liang Ge branch kept right collects can extend magnetic
Pole B;In Fig. 1, dash area is magnetic pole A and magnetic pole B.A coil, four coils it are wound around in each branch
Connect in a certain way;According to above-mentioned connected mode, can be to the Liang Ge branch kept left and the Liang Ge branch kept right
Coil passes to the electric current of different directions respectively.The special construction of this iron core, the iron core of left and right branch collects respectively
Become two magnetic poles, on the one hand magnetic field is effectively guided to magnetic pole, be formed at the uniform magnetic on certain turn-out track direction
, on the other hand, for the design of relative three magnetic poles, decrease production cost.Use multiple coil to produce
Raw bigger magnetic flux density.
Corner's design of iron core in existing Conventional monomodal type tracks of permanent magnetism magnetic turnout electric magnet is not conformed to
Reason, existing iron core corner is right angle, easily produces leakage field.And leakage field phenomenon makes to increase raceway surface
Magnetic flux density is more difficult.Making improvements, the iron core corner at electric magnet designs rounding, reduces
Leakage magnetic flux, increases the magnetic flux density that electric magnet produces.
In view of the particularity of magnetic turnout electric magnet, this electric magnet use have high saturated magnetic induction and
The ferrocobalt of high magnetic permeability, coil uses copper coil, increases magnetic flux density produced by electric magnet further.
In design, electromagnet core was less in the past, is easily saturated, and the magnetic flux density of saturated rear electric magnet is no longer
Increase along with the increase of electrical current, to this end, this electromagnet structure increases the core volume of electric magnet,
Core volume is designed as 20mm × 180mm × 260mm, to slow down core sataration speed, increases electric magnet institute
The magnetic flux density produced.
As it is shown on figure 3, the magnetic flux density through above-mentioned improvement electric magnet almost can be formed forever with former permanent magnet
Produced by magnetic orbital, magnetic flux density matches.
It is used for designing magnetic turnout by this electromagnet structure, as in figure 2 it is shown, electric magnet is perpendicular to turnoff forever
Magnetic orbital, the magnetic pole of magnetic turnout electric magnet embeds in tracks of permanent magnetism 2, and magnetic pole A and magnetic pole B is in point
The center of Cha Chu, the space of the most alternate one piece of permanent magnet size.In Y-shaped track, logical
Crossing the electric current being passed through different directions in magnet spool, the uniform magnetic flux being formed at certain specific direction is close
Degree, guide magnetic suspension train towards direction turn-out track,
Tracks of permanent magnetism uses Nd-Fe-B permanent magnet, for Halbach type tracks of permanent magnetism, has extremely strong poly-magnetic energy
Power, is the track arrangement mode that can be produced high-intensity magnetic field up to now by minimum permanent magnet consumption.
Above-mentioned magnetic turnout is utilized to carry out turn-out track, comprising:
Determine and treat turn-out track direction;
According to treating that turn-out track direction, to coil electricity, to treat to produce on turn-out track direction uniform magnetic field, turns non-waiting
Non-uniform magnetic field is produced on rut direction.
Fig. 3 is the magnetic turnout principle of Halbach tracks of permanent magnetism, when dolly needs, changes coil
(13a, 13b, 13c, 13d) sense of current make its direction of magnetization as shown in thick black surround 1a, i.e. at left track
(B) traffic direction defines uniform magnetic field so that dolly track to the left runs, and runs at right track simultaneously
The uneven magnetic field that direction is formed is further ensured that dolly traffic direction accurately.When dolly needs to turn right,
Change coil (13a, 13b, 13c, 13d) sense of current make its direction of magnetization as shown in thick black surround 1b, i.e.
Uniform magnetic field is defined so that dolly track to the right runs, simultaneously on a left side at right track (C) traffic direction
Track running direction forms uneven magnetic field and is further ensured that dolly traffic direction accurately.The energising of coil
Direction particularly as follows:
When needs turn left, the direction of magnetization of electric magnet is 1a, and during right-hand rotation, the direction of magnetization of electric magnet is 1b.
When needs are turned right, according to Ampere law, the energising direction of coil 13a, 13b (two kept left)
For in paper to outside paper;The energising direction of coil 13c, 13d is in paper extroversion paper, the now magnetic of electric magnet
Change direction identical with shown in 1b in Fig. 3, therefore can realize track switch of turning right the most smoothly.When needs turn left
Time, according to Ampere law, the energising direction of coil 13a, 13b (two kept left) is for export-oriented from paper
In paper;The energising direction of coil 13c, 13d is to paper in paper, now the direction of magnetization of electric magnet and figure
In 3 identical shown in 1a.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model,
For a person skilled in the art, this utility model can have various modifications and variations.All in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in this
Within the protection domain of utility model.
