美国阿贡尼国家实验室和英国爱迪生研究所共同开发了一种超级轴承,它能帮助电站有效地蓄能和重新产生电能。这种装置的摩擦力仅相当于其它轴承的1/3。 这种轴承由钕铁硼永磁材料构成,它安装在真空中由液氮致冷的超导体上旋转,阿贡尼的工程师约翰霍尔称,永磁钢与超导体的形状像两块煎饼,其直径为10cm。 真空室上部的线圈是通电的,从而产生一个磁场,转动安装在永磁钢上的飞轮。旋转的飞轮可以将它所接收到的90％的电能反馈回去。目前,这部样机太小,无法大量蓄能。最终目标是制造一个40吨重的飞轮,能贮存10MW。夜间用电少,产生的电能可以储存在飞轮里,到白天取出来再用。飞轮也可装在卡车上,因而可供紧急发电用。
Argonne, the United States National Laboratory and the British Institute of Edison co-developed a super-bearings, it can help the power station to effectively store energy and regenerate electricity. The friction of this device is only equivalent to 1/3 of the other bearings. This bearing is made of NdFeB permanent magnet material, which is mounted on a superconductor cooled by liquid nitrogen in a vacuum. Agonie’s engineer John Hall said the permanent magnet and superconductor are shaped like two pancakes, Diameter is 10cm. The upper coil of the vacuum chamber is energized to create a magnetic field that rotates the flywheel mounted on the permanent magnet. The rotating flywheel can feed back 90% of the energy it receives. At present, this prototype is too small to store large amounts of energy. The ultimate goal is to create a 40-ton flywheel capable of storing 10 MW. Less electricity at night, the resulting electrical energy can be stored in the flywheel, to remove it during the day and then use. The flywheel can also be mounted on a truck for emergency power generation.
