摘要
防雷装置的使用效能取决于电气连接性能,我国国家和地方防雷测试标准对防雷装置的电气连接性能有明确的检测指标和测试要求,特别是目测难以保证质量的隐蔽项目需要测试过渡电阻和接地电阻等参数。借鉴国际、国外标准的相关测试要求,以一个实际防雷工程检测项目为例,探讨我国防雷装置电气连接性能测试方面的不足。
The effectiveness of lightning protection system depends on the electrical connection performance.China’s national and local standards for lightning protection test specify the test indexes and requirements for the electrical connection performance of lightning protection system.Especially for hidden items of which the quality cannot be guaranteed through visual inspection,transition resistance and earth resistance shall be tested.Requirements for relevant test specified in international and domestic standards are used for reference,and an actual test project of lightning protection engineering is taken as an example to discuss China’s shortcomings of electrical connection performance test on lightning protection system.
