本文利用等电势原理设计了一种井下参数测量装置远程供电系统，文中首先对等电势原理进行了介绍，通过地面三相电抗器，供电系统提供的直流电可以为井下测量装置远程供电。文中对地面供电系统电路进行了设计，系统的主体是较宽输入电压范围内都能保持稳定输出的反激变换电路，实验证明其电压调整率为0.36%，负载调整率为0.42%，均满足设计要求。
In this paper, a remote power supply system based on principle of equal potential for downhole parameters measurement instrument was designed. This paper introduced principle of equal potential. According to it, the DC power supply system could power downhole measurement instrument remotely by the uphole three-phase reactor. The circuit of power supply system was designed. Its main part was a flyback circuit with steady output voltage in spite of wide-ranging input voltage. According to experiment result, its voltage regulation was 0.36% and load regulation was 0.42%, which fulfilled the design demand.
