本文着重分析了在吉林油田采用“双升压”（即井排高压线路从６ｋＶ升到１０ＫＶ，低压线路从３８０Ｖ升到６６０Ｖ）供电系统的必要性、可行性、优越性以及所获得的经济效益。
This article focuses on the analysis of the necessity, feasibility, advantages and economic benefits of using “double-step-up” (ie, increasing the well-row high-voltage line from 6kV to 10kV and low-voltage lines from 380V to 660V) .
