摘要
针对当前建筑电气工程中电气设备在雷暴天气易出现跳闸,影响电气设备运行安全性和稳定性的问题,开展防雷接地技术及其应用研究。分析瞬间过电压,划分防雷区域,为避免脉冲磁感应强度过大导致电气设备失效,进行屏蔽防护;通过电气设备工作接地与安全接地,实现防雷防护。实例证明,应用新的防雷接地技术后,雷暴天气电气设备连接线路不会出现跳闸情况,有效提高了电气设备运行稳定性。
Research on lightning protection and grounding technology and its application is conducted to address the issue of electrical equipment tripping during thunderstorm weather in current building electrical engineering,which affects the safety and stability of electrical equipment operation.Analyze instantaneous overvoltage,divide lightning protection areas,and provide shielding protection to avoid electrical equipment failure caused by excessive pulse magnetic induction intensity.Realize lightning protection through electrical equipment grounding and safety grounding.The example proves that after applying the new lightning protection grounding technology,the connection lines of electrical equipment in thunderstorm weather will not trip,effectively improving the operational stability of electrical equipment.
