摘要

本文主要提出一种基于单线圈涓流式高压线路电流传感装置，并详细阐述了单线圈涓流技术的实现方法。该装置主要使用一个电流互感器，即可实现高压线路上的能量提取和电流感测，在重量和体积上具有明显优势，而且更加的小巧轻便，方便安装。另外，装置主要采用超级电容来存储从高压线路提取的电能，并通过超级电容放电，为装置的正常工作提供电能。同时在超级电容电路周围设计了配套保护电路，使其适应变化范围很宽的电流。%This paper describes the single-coil current sensing device installed in higher voltage lines for trickle charging, and presents the method of single-coil current sensing device for trickle charging. The device can achieve the function of obtaining electricity and monitoring the current for using only one current transformer. This device has many obvious advantages in weight and volume, and it is small and easy to install. In addition, the device with the super capacitor can store electrical energy from higher voltage lines, and this super capacitor discharges to provide electrical energy for the device. At the same time, there are some protection circuits around the super capacitor, so the device could monitor the wide range of current.
