摘　　要：以直流钻机在实际钻进工况期间测量的无功、谐波电流、谐波电压为基础;简要分析了这些因素对电网的影响;提出了在以工业电网为动力时对这些因素的应对措施;说明了对钻机影响最大的问题在于谐波电压可能会使数字型开关电源装置中的电解电容器过热而烧毁。Based on the reactive power,harmonic wave current and voltage of DC drilling rig under actual working condition,this paper briefly analyses the effect of these factors on power grid,puts forward the solutions to these factors when industrial power grid is used as power source,and illustrates that the harmonic wave voltage may cause the electrolytic capacitors in the digital switching power supply unit to overheat and burn down.
