输电线路在线监测系统的电源解决方案

Power solutions of high-voltage on-line monitoring equipment

目前在输电线路的自动化改造中,由于监测设备一般安装于野外,使得设备工作电源的获取和现有的低压监测设备有很大的不同。现阶段流行的光伏电源系统系统由于材料稳定性的原因,使其在使用上完全不能满足设备长期可靠工作的要求。针对目前几种主要的取能方案进行分析比较,在此基础上提出了一种以感应取能为基础的新电源解决方案,该方案不但在设计原理上克服了光能和风能取电的弱点,同时还克服了常规耦合取电方式中电源适应面过窄,使用寿命和使用范围受输电线路工作状态影响很大的问题。

Because the monitor device is installed in the filed during the auto-reconstruction of the transmit electricity lines,the power supply of the monitor device is very different with the low voltage equipment. The current solar energy can not satisfy the long reliable work of the device due to the poor stability of the material applied in the PV system. In this paper, the several options were analyzed, and based on the analysis, a new solution was provided, which could overcome the shortcomings of the existing way and greatly increase the adaptatlity of equipment.
