电力巡检机器人移动式无线充电系统分析与验证OA北大核心

To improve the degree of intelligence of a substation and cut down the cost of inspection,substation in-spection robots instead of the human labor are employed to perform daily inspections.However,the battery life greatly limits the work of inspection robots,so the full-time inspection cannot be realized.To solve this problem,a dynamic wireless charging method is used to charge the robots,so that the robots can perform inspections while charging and real-ize full-time inspection.In this paper,the relationship between coil mutual inductance and system efficiency is analyzed at first.Then,aimed at the segmented primary coil rails used in the dynamic wireless charging system,a soft-switching method for rails is put foiward to reduce the inrush current during the switching process,thus protecting the circuit com-ponents.Finally,the influence of coil mutual inductance on the system efficiency was verified by experimental results,and the feasibility and effectiveness of the soft-switching method for rails was also proved.
