500 kV新型防雷绝缘子仿真与试验分析

Dianci bileiqi
提高输电线路防雷能力，常采取安装避雷器和降低接地网接地电阻的方法，但前者安装维护难度大，后者经济性较差。为此，文中提出一种利用500 kV新型防雷绝缘子提高线路防雷能力的方法。该新型绝缘子经带环形ZnO电阻片的穿心结构避雷器与普通绝缘子串联进行实现。本研究通过ATP-EMTP软件搭建500 kV输电线路模型，对比分析安装新型防雷绝缘子和普通绝缘子线路，遭受反击、绕击时的过电压波特点。同时，通过雷电冲击闪络、操作冲击的现场试验对其防雷能力进行了充分验证。仿真和试验结果表明：线路遭受雷击时 ...

钳形环路电阻测试仪在防雷检测质量考核中的作用

Dianci bileiqi
文中结合笔者近几年参加防雷检测质量考核工作的实际情况，通过简单分析钳形环路电阻测试仪的测量原理和使用范围，以及到雷电防护重点单位现场开展防雷安全隐患排查的实践操作，验证在某些场合使用钳形环路电阻测试仪进行防雷安全检测的重要性，最后指出该测试仪在使用过程中的注意事项及优缺点。本研究旨在进一步提高质量考核人员对钳形环路电阻测试仪的认知度，提升防雷检测资质单位检测质量，并指导日常防雷安全监管隐患排查工作。
