在高压电力线上安装的在线测量装置需要持续可靠的电能供应，提出了一种新的通过感应高压电场来获得能量的电源技术。这种技术的主要思想是通过安装在电力线与大地之间的一个金属极板来获得恒定的位移电流，使之向一个小容量的取能电容充电，进而通过一个放电电路将能量转移到一个大容量的储能电容上，当存储的能量达到一定水平，则提供给后端的测量装置。由于电力线的电压是稳定的，因此这种供电方式较少受到负载和环境的影响。文中详细介绍了放电法电场感应取能技术的主要原理和优化设计方法，并将之应用于一种隔离开关触头温度在线测量和无线传输装置中，该系统已经在110 kV 变电站中成功挂网运行，从而验证了技术的有效性。

Sustained and reliable power supply is required by an online measuring device installed on high voltage transmission lines.A new power supply technology based on electric-field induction is proposed,the main idea of which is a constant displacement current is induced from a metal sheet installed between power line and earth to discharge a small energy-acquiring capacitor.Then,the stored energy will be transferred to another large energy-storing capacitor by means of a discharge circuit. Once the stored energy gets enough,it will supply a subsequent measuring device.Since the voltage of power line is stable, this power supply mode is less affected by the load and environment.The principle and optimal design of this electric-field induction energy-acquiring technology based on the discharge method is described in detail.The technology is applied in a temperature measuring and wireless transporting system for disconnecting switches.The effectiveness of the power supply technology is verified by the system”s successful online operation in a 1 10 kV substation.
