电气接地技术的应用实践与故障问题

Application practice and fault problems of electrical grounding technology

电气接地系统在水利工程中的安全要求越来越高,但实际应用中常出现故障,影响设备运行安全。文章研究了接地技术类型与作用,包括工作接地和保护接地;分析了接地系统应用中的故障原因,如设计不合规、施工不规范等。为提高接地系统的可靠性,提出了有效措施:合理布线设计、严禁混接PE线与N线、加强电缆屏蔽与保护接地、规范施工管理、加强建筑物等电位联接。这些措施有助于预防接地故障,提高系统的稳定性和安全性。

The safety requirements of electrical earthing system in water conservancy projects are getting higher and higher,but faults often occur in practical applications,affecting the safety of equipment operation.The article studies the types and functions of grounding technologies,including working grounding and protective grounding;the fault causes in the application of earthing system are analyzed,such as design non-compliance,construction irregularities,etc.In order to improve the reliability of the earthing system,effective measures are proposed:reasonable wiring design,no mixing of PE lines and N lines,strengthening cable shielding and protective grounding,standardizing construction management,and strengthening equipotential bonding of buildings.These measures help prevent ground faults and improve the stability and safety of the system.
