摘　　要：某型测试系统在测试作业中,接地电阻的技术指标为小于3Ω,但由于野外环境条件差异,其接地电阻往往难以满足指标要求。在分析接地电阻影响因素的基础上,提出了一种基于“组合接地网”的接地方法。实验证明该方法构造简单,实验设备便于携带,能有效地解决野外环境下接地电阻降阻值难的问题。In the test operation of a test system,it is required that the grounding resistance should be less than 3Ω.However,due to the difference of field environmental conditions,its grounding resistance is often difficult to meet the requirements of the index.Based on the analysis of the factors affecting the grounding resistance,a grounding method based on the“combined grounding network”is proposed.The experiment proves that the method is simple in construction,the experimental equipment is easy to carry,and it can effectively solve the problem that the grounding resistance is difficult to drop in the field environment.
