Description
Technical field
The utility model relates to a kind of superconduction-permanent magnetic hybrid magnetic suspension bearings system for flywheel energy storage, belongs to the magnetic material technical field that magnetizes.
Background technique
Flywheel energy storage system is one of at present more advanced energy storage technology, compare with traditional chemical energy storage have that power is large, efficiency is high, the life-span is long, the plurality of advantages such as pollution-free, strong adaptability, applied range.Bearing arrangement in flywheel energy storage system is used for support flying wheel rotor, is one of key factor of restriction Speed of Reaction Wheels, and the frictional force of bearing arrangement and stability directly affect life-span and the normal operation of whole flywheel energy storage system.The supporting way of flywheel mainly contains four kinds of super-conductive magnetic suspensions, electromagnetic suspension, permanent magnet suspension, mechanical bearing.Because Speed of Reaction Wheels is very high, mechanical bearing can be because life-span and consumed energy be shortened in friction when High Rotation Speed; Electromagnetic suspension bearing also needs to consume certain energy because will realize the control of stability.Therefore super-conductive magnetic suspension and permanent magnet suspension are as the optimum supporting way of bearing.
Super-conductive magnetic suspension, because diamagnetism and the pinning performance of superconductor realizes self-stabilization suspension, combines the advantage of electromagnetic suspension and permanent magnet suspension.Super-conductive magnetic suspension not only can provide axial constraint, and radial constraint is also provided.But for vertical super magnetic suspension, it mainly bears thrust load, and its axial rigidity is much larger than radial rigidity.In flywheel energy storage system, in order to realize the High Rotation Speed of flywheel, the super-conductive magnetic suspension bearing of depending merely on two axle heads is difficult to realize stable, must apply in the radial direction extra constraint to guarantee flywheel stable rotation at a high speed for this reason.
Model utility content
The purpose of this utility model is the magnetic suspension support technology problem for the above-mentioned flywheel of current existence, and a kind of superconduction-permanent magnetic hybrid magnetic suspension bearings system for flywheel energy storage is provided.This bearing can improve bearing radial rigidity, thereby guarantees the stable rotation of flywheel rotor high speed.
For achieving the above object, design of the present utility model is:
The superconducting magnetic bearing system of same axle head and Permanent-magnet bearing share a p-m rotor.Superconductor in super-conductive magnetic suspension bearing is placed in the container that fills with liquid nitrogen, makes it present superconductivity, is used as the stator of superconducting magnetic bearing system; The permanent magnet rotor of bottom is subject to the suspending power making progress of superconductor, realizes stable suspersion; The permanent magnet rotor on top is subject to the pulling force making progress of superconductor, realizes stable suspersion.The outer permanent-magnetic clamp of the Permanent-magnet bearing at axle two ends is as stator, and outer shroud is identical with the axial charging direction of interior ring.
According to above-mentioned design, the utility model adopts following technological scheme:
A kind of superconduction-permanent magnetic hybrid magnetic suspension bearings system for flywheel energy storage, comprise superconduction-permanent magnetic hybrid magnetic suspension bearing and rotating shaft, superconducting block and permanent magnet form superconducting bearing, superconducting block is the stator of superconducting bearing, permanent magnet is the rotor of superconducting bearing, and described superconducting block is positioned in cooled with liquid nitrogen container; Permanent magnet and permanent-magnetic clamp form Permanent-magnet bearing, the rotor that permanent magnet is Permanent-magnet bearing, the stator that permanent-magnetic clamp is Permanent-magnet bearing; It is rotor that superconducting bearing and Permanent-magnet bearing share permanent magnet, forms superconduction-permanent magnetic hybrid magnetic suspension bearing, and rotating shaft two ends are connected with permanent magnet, and rotor and the flywheel of motor is housed in described rotating shaft.
Described superconducting block is annulus, and the diameter of superconductor is than the little 2mm-5mm of permanent magnet diameter; When cold height is high then and there, the axial clearance between superconductor and permanent magnet is between 0.5mm-5mm; When cold height is low then and there, the axial clearance of superconductor and permanent magnet is between 3mm-10mm.
