摘　　要：输电线路中接地装置保持良好的接地性能直接关系着输电线路的安全运行。基于CDEGS仿真平台建立新型接地模型计算石墨基柔性降阻布的降阻效率,其降阻效率都达到25%~35%左右,并且随着降阻布敷设面积的增大,降阻效率逐渐提高。开展了模拟雨水冲刷石墨基柔性降阻布试验。结果表明:在雨水冲刷作用下降阻布可以保持长效稳定性。实际工程应用表明,石墨基柔性降阻布直接敷设在接地体下面,铺设和连接方便,其降阻效率可达到70%以上,降阻效果显著。The good grounding performance of the grounding device in the transmission line is directly related to the safe operation of the transmission line. Based on the universal CDEGS simulation platform, a new grounding model was established to calculate the drag reduction efficiency of graphite based flexible drag reduction cloth. The drag reduction efficiency reached about 25% ~ 35%, and with the increase of the laying area, the drag reduction efficiency gradually improved. The simulation results of rain-washed graphite based flexible drag reducing cloth showed that it could maintain long-term stability in rain-washed effect. The practical engineering application showed that the graphite based flexible drag reduction cloth was laid directly under the ground body, which was convenient for laying and connecting. The drag reduction efficiency was over 70%, and the drag reduction effect was remarkable.
