Description: 本论文对国内外光电式电流互感器的供能方式进行了总结，论述了其优缺点。其中，基于超声波供能的光电式电流互感器是目前的最新研究成果，目前的研究已经验证了其可行性，但是存在传输效率低的严重问题。超声波供能系统的研究，需要大量的力学实验，不便于实现。本论文通过对力学中超声波的波动方程进行推导，寻找出了一组和电学中传输线方程相类似的方程组。通过对比电学和力学中的物理量，得到了它们之间的对应关系。在此基础上，构建出了超声波传能装置的等效电路模型，并进行了仿真实验。通过在电学中的仿真结果，较为直观的反应出了超声波传能装置的物理属性与能量传输效率的关系。超声波传能装置电学模型的仿真实验，取代了很大一部分的力学实验，简化了实验手段，为后续的研究提供了一种新的方法-The energy-provision ways of domestic and international Optical-Electric current transformer are summarized in this paper. The summarization shows both the advantages and disadvantages of these ways. Among all of the researches, Optical-Electric current transformer with ultrasonic power supply is the advanced research production nowadays. The results of the present research have testfied the feasibility of this project,but the transmitting efficiency is very low. Research on ultrasonic power supply requires a mass of mechanics experiments which are hard to work. In this paper, we find a set of differential equations by the derivation of the wave equation in ultrasonic. They are similar to the equations of transmission line in electricity. By the contrast of physical quantities in electricity and mechanics,we find out the corresponding relationship between them. Based on this conclusion, an equivalent circuit model of the ultrasonic power supply device is designed. The Simulation resul
