摘　　要：Y/Δ转化器在低负载率时,节电效果较好。可控硅调压控制器在高负载率时,节电效果较好。采用高精度三相电能计量芯片ATT7022A,设计了一种结合两者优点的抽油机节能控制仪。对抽油机电动调压节能系统的软硬件设计做了较详细的分析。通过在多口油井上安装Y/Δ可控硅调压组合式抽油机节能控制仪,并对5口井进行了现场对比测试,单口井年节电约2.1万kW.h。The energy-saving effect of Y/Δ change-over controller is better than the silicon controlled rectifier（SCR） voltage regulating style when the load rate of oil-pumping unit is less;.but the silicon controlled rectifier（SCR） voltage regulating style is better than the energy-saving effect of Y/Δ change-over controller when the load rate of oil-pumping unit is higher.Based on high-precision three-phase electrical energy measurement IC-ATT7022A,an new energy saving controller of combining the advantages of both controllers is designed.On the analysis of based on the principle of voltage regulating and energy saving of electric motor of pumping units,The system＇s design of software and hardware are made.Through the installation of Y/Δ-SCR controller and comparison tests at the scene in five oil wells,every well saves 21 000 kW·h annual.
