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
