变电站防雷接地技术

Lightning Protection and Grounding Technology of Substation

现如今社会用电量需求不断增加,电网建设规模随之不断扩大,变电站有着越来越复杂的系统,所用的设备也不断增多。为了保证变电站运行稳定,确保各个设备、系统能够正常地运转,提高供电质量,应充分做好防雷节点保护措施,合理设计并且安装防雷接地线路,将变电站运行的可靠性提高。通过设置防雷接地系统可以将雷电和静电对变电站产生的危害降低,避免发生触电事故或者短路问题。为了进一步提高变电站防雷接地水平,文中重点探讨雷电危害和变电站防雷接地施工技术。

Nowadays,the demand for electricity in society is increasing,and the scale of power grid construction is expanding.Substations have more and more complex systems,and the equipment used is also increasing.In order to ensure the stable operation of the substation,ensure the normal operation of all equipment and systems,and improve the quality of power supply,it is necessary to fully take lightning protection node protection measures,reasonably design and install lightning protection grounding lines,and improve the reliability of substation operation.The lightning protection and grounding system can reduce the harm of lightning and static electricity to the substation and avoid electric shock accidents or short circuit problems.In order to further improve the lightning protection and grounding level of substation,this paper focuses on the lightning hazard and the lightning protection and grounding construction technology of substation.
