摘要
针对以泥浆发电机为供电方式的自动垂直钻井工具,提出了一种大功率非接触式电能传输系统。利用电磁感应原理与变压器理论,结合高频逆变技术实现了钻井工具中的电能从转子到定子的非接触式的耦合传输,并满足井下近钻头处随钻仪器设备的大功率供电需求,性能稳定可靠、电能效率达到80%。
This article introduces a contactless induction power transmission system base on the mud generator in automatic vertical drilling tools, which uses electromagnetic induction and transformer theory, combined with high-frequency inverter circuit to achieve a contactless induction power transmission from the rotor to the stator. It meets the requirement of power supply for the near drill bit drilling equipment, stable performance and energy efficiency can reach 80%.
