摘要
在线监测装置是保证高压线路安全稳定运行的重要组成部分,但受限于户外的运行环境,该装置缺乏稳定的供电电源.文章提出一种基于恒流源特性的电场感应取能电源,通过换能器有效放大高压导线与大地之间的恒定位移电流,可满足高压架空输电线路低功率传感器的功率需求.首先,建立基于恒流源特性的电场感应取能电源的电路模型,分析其关键影响因素;其次,针对影响因素进行理论和仿真分析,以优化参数配置;最后,将该取能电源应用于一种隔离开关触头温度在线测量和无线传输装置,分析其应用效果.本研究为在线监测装置的户外供电提供了一种新的方式.
Abstract
On-line monitoring device is an important part to ensure the safe and stable operation of high-voltage lines,but limited by the outdoor operation environment,the device lacks stable power supply.In this paper,an electric field induction power supply based on the characteristics of constant current source is proposed,which can effectively amplify the constant displacement current between the high-voltage conductor and the earth through the transducer,and can meet the power demand of low-power sensors of high-voltage overhead transmission lines.Firstly,the circuit model of electric field induction energy extraction power supply based on the characteristics of constant current source is established,and its key influencing factors are analyzed.Secondly,the influencing factors are analyzed theoretically and simulated to optimize the parameter configuration.Finally,the power supply is applied to an on-line temperature measurement and wireless transmission device of disconnector,and its application effect is analyzed.This study provides a new way for outdoor power supply of online monitoring devices.
