摘　　要：针对高压输电线路上能耗较大而体积重量要求严格的设备或需要在线快速充电的设备的能量补给问题,提出了一种以蓄电池为储能单元的感应取电电源装置方案.理论分析和实验研究表明:在相同材料的铁芯下,最大取电功率与铁芯截面积、输电导线电流成正比;在相同材料的铁芯和相同的电池电压下,最优次级绕组匝数与铁芯截面积成反比.开发了一种相对独立的、用于输电导线移动或固定设备电能补给的可开合式感应取电电源装置,并在作者研制的巡线机器人上得到了成功应用;最后给出了感应取电电源装置现场运行的实验结果,证明了该方案在实际运用中的稳定性、可靠性和有效性.The research on power supplement system for power induction devices,featured with large power consumption,small volume,light weight,and fast recharge rate,is introduced.A scheme of power induction taking battery as energy storage unit is proposed systematically and comprehensively.Theoretical analysis and experimental tests are carried out and two conclusions can be drawn as follows： with the iron core material unchanged maximum power output of draw-out winding is positive proportional to cross-section area of iron core and current amplitude of the transmission line;in addition,when the iron core material and battery voltage are unchanged optimal secondary winding turns is inversely related to cross-section area of iron core.A relatively independent automatic power supplement device is developed for the equipments moving along or fixed to transmission line;and it has successfully been applied to self-developed inspection robot.Finally,the results of field tests are also given;and the scheme proposed is proved to be stable,reliable and efficient in practical running.
