Examples
- According to the topology of the substation and resistance measurements of down - leaders , the erosion diagnosis equation is built and the resistance variations of grounding grid branches are solved , and the erosion of grounding grid could be found through the fuzzy diagnosis regulation
利用接地网拓扑结构图及接地网引下线间的电阻测量值,建立腐蚀诊断方程,通过求解诊断方程,计算出接地网支路电阻值变化量,采用模糊诊断方法判断出接地网导体腐蚀的情况。 - Big separated scales integrating with standing node when do elementary diagnosis is a good method to large - scale grounding grid . the number of the nodes for elementary diagnosis is ten percent of the total grid nodes number . and the erosible grid areas , important electrical equipments areas and the down - leaders areas should be considered enough
初步测量节点数的选择以接地网节点总节点数的10 %为宜,另应充分考虑接地网可能腐蚀的区域,重要电气设备区域、接地引下线分布等情况。 - The research shows that the protection of the industrial control system are not only need the external lightning protection system such as air terminals , down conductors and grounding system , but also need the internal lightning protection system such as equipotential bonding , shielding and surge protection of information system and electrical system
经研究，对工业控制系统的防雷保护不仅要做好接闪器，引下线，接地体等基本的外部防护，还要做好等电位联结，屏蔽，信号系统和电源系统的电涌保护等相关内部防雷措施。
