接地的重要性

摘要

本文通过对发电厂、变电所实际接地及相关问题的分析，阐述了保护接地、接触电压和跨步电压等概念，说明了接地技术的重要性，并指出，伴随着高科技信息化时代的到来．接地技术将在各个领域得到更为广泛的应用，并且形成系统化的“接地学学科”%In this paper the analysis of grounding in power Stations,substations and associated problems are given. Also given the conelpts of protecting grounding,warking grounding and step voltage, and their importance are described. It was pointed out that with development of.science and technolagy, the grounding technigul will be used in many engineering areas.
