本发明公开了一种井下旋转导向的能量信号同步传输耦合机构设计方法，涉及石油钻探井下旋转导向的电能传输装置技术领域。本发明将能量线圈和信号线圈串联在同一块区域，可以解决系统占用空间大，成本高的问题。为解决能量对信号的干扰问题，本发明对能量线圈和信号线圈进行设计，信号线圈相较于能量线圈而言，信号线圈绕制的感值偏小，用于信号传输，而能量线圈绕制的感值比信号线圈大，用于能量的传输。在高频下，信号发射线圈的等效阻抗较小，且功率等级低，对能量传输的影响可忽略，由于信号线圈绕制稀疏，能量线圈和信号线圈之间的互感较小，能量对信号传输的影响也较小，这样就能有效减小在无线电能传输过程中能量对信号的干扰。 The invention discloses a design method of an underground rotary steering energy signal synchronous transmission coupling mechanism, and relates to the technical field of underground rotary steering electric energy transmission devices for oil drilling.
