摘　　要：搭建了户外实体接地装置试验场,用于探索不同接地材料、不同敷设深度、不同接地面积及不同接地体长度影响条件下的接地装置阻抗情况。通过对不同接地网模型的实际测量,确认了接地阻抗值直接取决于接地体的面积,接地材料、敷设深度和接地体长度对接地装置阻抗值影响较小。The outdoor solid grounding device test field is built to explore the impedance of grounding device under the influence of different grounding materials,different laying depth,different grounding area and different grounding body length.Through the actual measurement of different grounding grid models,it is confirmed that the grounding impedance value directly depends on the area of grounding body,and the grounding material,laying depth and grounding body length have little influence on the impedance value of grounding device.
