Abstract

The invention discloses a device and method for testing the supporting characteristics of a high-temperature superconductive suspension type flywheel rotor, and the device comprises a vacuum chamber, a cross-shaped sliding table, a first clamping structure, a second clamping structure, and a driving mechanism, and the first clamping structure clamps and fixes a superconductive stator at a preset position in the vacuum chamber. The second clamping structure clamps and fixes the rotor penetrating into the superconducting stator, the second clamping structure is arranged on the cross-shaped sliding table, the rotor is in power connection with the driving mechanism through the rotating shaft, and the rotor can be driven to move in the transverse direction and the longitudinal direction of the horizontal plane through movement of the cross-shaped sliding table, wherein a displacement sensor for sensing the horizontal relative position of the rotor and the superconducting stator is arranged on the rotating shaft, and a force sensor for sensing the axial suspension force and / or the radial suspension force is arranged in the axial direction and / or the radial direction of the superconducting stator. According to the invention, a field cooling position of the high-temperature superconducting suspension type flywheel can be adjusted to reach the optimal state, and the measurement of operation parameters in static and dynamic rotation states can be realized.

Description

technical field [0001] The invention relates to the technical field of flywheel energy storage, in particular to a testing device and method for the supporting characteristics of a high-temperature superconducting suspension type flywheel rotor. Background technique [0002] Flywheel energy storage is an environmentally friendly energy storage technology that stores and releases energy through high-speed rotating flywheel inertia blocks. Flywheel energy storage mainly includes the flywheel rotor, motor and control system. In order to increase the flywheel energy storage capacity, it is usually achieved by increasing the speed and moment of inertia. Therefore, the flywheel rotor must not only meet the load requirements, but also deal with the gyroscopic effect and friction loss of high-speed rotation. . The high temperature superconducting suspended flywheel rotor is a self-suspending, non-contact self-stabilizing rotor without control. Its advantage is that it does not req...
