Abstract

The invention discloses a magnetic levitation flywheel energy storage battery, the structure of which comprises a battery shell, a storage battery, an accelerating flywheel, an external rotating shaft, a magnetic levitation flywheel and a magnetic levitation power generation device, adopting a longitudinal magnetic levitation bearing and a lateral limit magnetic levitation bearing, avoiding the flywheel energy storage battery System vibration and gyro effect. The increased acceleration flywheel structure enables the magnetic levitation flywheel to be accelerated to the greatest extent, so that it can always receive the acceleration benefits of the outside world and avoid the deceleration benefits of the outside world. The combination of electromagnetic transmission and contact transmission is adopted. First, through electromagnetic flexible transmission, slow down Slowly increase the rotation speed of the power generation device, and then use contact transmission, so that the power generation device can get a good transition from stationary to high-speed rotation, and at the same time, the transmission efficiency will not be lost, so as to avoid the damage of the rotating shaft caused by the forced speed increase of the power generation device and rigid collision, and the power generation device will also be damaged. Magnetic levitation design is adopted to avoid friction loss, improve transmission efficiency, and improve kinetic energy utilization.

Description

technical field [0001] The invention belongs to the field of flywheel application technology, and in particular relates to a magnetic levitation flywheel energy storage battery. Background technique [0002] Among various energy storage technologies, the development speed of chemical energy storage has always been ahead of that of physical energy storage. With the improvement of the energy system's demand for energy storage technology, physical energy storage technology, which has always been known for its low environmental pollution and high operational stability, is being developed. The temperature rises rapidly, among which the flywheel energy storage has the characteristics of fast charging and discharging, and the highest energy density. The flywheel energy storage system is composed of high-speed flywheel, bearing support system, motor, generator, power converter, electronic control system and additional equipment such as vacuum pump and emergency backup bearing. At v...
