Abstract
According to the wireless power transfer system (WPT) in oil-gas downhole, the structure of the WPT device suitable for the simultaneous existence of oil-water medium in high-temperature and high-pressure environment is put forward by using the principle of electromagnetic induction. Through the analysis of magnetic circuit, the electromagnetic mutual inductance coupling model is established, and the main factors affecting the transmission efficiency are obtained. Based on the model, the system is simulated and verified by experiments, in order to further improve the efficiency of power transfer system.This publication has 1 reference indexed in Scilit:
