摘　　要：为能够为SF6气体绝缘组合电器设备(GIS)局放在线报警系统提供电能,设计了一种基于电磁感应原理的无线取能系统。利用取能线圈从GIS盘式绝缘子外侧感应工频磁场,线圈两端的感应电势经整流电路后,应用具有电池管理功能的超低功耗升压充电器,将感应电能收集与管理,通过升压稳压电路为系统提供电能。通过理论分析和软件仿真,验证了该取能方案的可行性,满足系统的需求,有效解决了取能线圈输出电能低而无法满足系统工作的问题。结果表明,该取能电源能够周期性地为在线报警系统提供可靠的电能。In order to provide energy for GIS partial discharge online alarm system, a wireless draw-out power system was designed based on electromagnetic induction principle. Using draw-out power coil to induct power frequency magnetic field from the lateral disc insulator of GIS, and ultra-low power booster charger with battery management functions was applied to collect and manage induction power through the rectifier circuit, providing power to the system by the boost regulator circuit. Through theoretical analysis and software simulation, the feasibility of this solution was verified,effectively solving the problem of lower power from draw-out power coil which is unable to meet the system. The results show that this draw-out power supply can periodically provide sufficient energy for online alarm system.
