超级电容回收再生能源技术 摘要：超级电容器是一种高效、实用、环保的能量存储装置。在轮胎式龙门集装箱起重机（RTG）中，超级电容器能够保存所有机构反馈的能量，避免了反馈能量的损耗，在荷载突增的情况下(起升瞬间)提供补充能量，平稳发动机工作状态，达到节能的目的。在起重机动力系统电路中，工作电压大大超过了单体电容的最大允许值，需要多个单体电容合理连接才能满足电压要求。超级电容器在装备机械、电动汽车、消费类电子 HYPERLINK /dianyuandianlu/ \t _blank 电源、军事、工业等高峰值功率场合有着广泛的应用。当前美国、日本、俄罗斯的产品几乎占据了整个超级电容器市场，我国在超级电容器领域的研究与应用水平明显落后于世界先进水平。 Super Capacitance Technology for Renewable Energy Recycling QU Wei-ping, LIN Yan ? Abstract: Supercapacitor is a high efficient, practical and environmental friendly device for energy storage. In rubber-type gantry cranes (RTG), super capacitors may save the energies fed back from all the mechanisms, so they may prevent feedback energies from wasting. When load sharply increases at the moment of lifting, supplement energies can be supplied to keep engines operating normally and the purpose of energy saving may be realized. In the power system circuit of cranes, operating voltage is larger than the maximum permissible value of single-chip capacitors. In order to meet the demand for voltage, it is necessary to reasonably connect several single-chip capacitors. Super capacitors are widely used in high peak power situations such as machinery and equipment, electric automobile, consumption electronic power supplies, military affairs, industry etc. Currently, the products produced by America, Japan and Russia almost take up the whole market for super capacitors. However, the Chinese research and application levels in the field of super capacitors obviously lag behind international advanced levels.
