摘要:
建筑物接地系统雷电冲击特性主要是指雷电流通过接地装置向周围大地散流的特征,通常表现为冲击电流对接地装置作用后局部暂态地电位升高导致地电位反击。利用土壤测试数据及接地系统图模拟实际建筑物接地模型下雷击冲击试验反击地电位特性,通过搭建CDEGS地电位仿真模型实现地电位分布计算并验证了反击试验结果的可靠性,得出地电位分布与注入点位置、接地系统支路分布之间影响关系,对雷击分流接地系统预防地电位反击提出了合理优化措施。
Abstract:
The lightning impulse characteristic features of building grounding system mainly refers to lightning current through the grounding device to the surrounding earth by scattered streams, usually presents that ground potential counterattack caused by partial transient ground potential rise after the effect of impulse current on device. The soil test data and the grounding system diagram model are used to simulate the lightning impulse test counterattack ground potential features under actual building ground, the potential distribution calculation is realized and the reliability of the test results are verified through constructing CDEGS ground potential simulation model, the influence relationship between potential distribution and injection point location, grounding system branch distribution is obtained, reasonable optimization measures are proposed for lightning distribution grounding system to prevent potential counterattack.
