摘　　要：雷电流参数的测量是进行雷电研究的基础工作,对于研究雷电特性、分析雷害事故、鉴定雷击跳闸事故责任、探讨防雷对策及为绝缘配合设计提供精确的原始数据均具有十分重要的意义。在电力系统防雷保护与雷电特性基础研究工作中,雷电流的最大陡度、幅值具有重要的意义。该文采用记录品质较好的金属磁带作磁卡的磁层,对雷电流幅值、最大陡度进行了实地测量,并对测量数据进行了深入的研究。进而提出中国桂林地区雷电流最大陡度与幅值的频率分布曲线,为电力系统的防雷研究提供了很好的手段和真实的数据。Measuring of lightning parameters is the base of lightning research. It is very important for researching the lightning characteristics, analyzing the accident of lightning, identifying the responsibility of lightning strike outage accident and discussing the strategies of lightning protection. It also can provide precise original data for designing insulation coordination. The max lightning steepness and lightning peak current have the important significance to the base researching work of the lightning-protection in the power system and the lightning characteristics. This paper takes the road tests in engineering fields using the magnetic card with the magnetic layer of the best recording effect metal tape to detect the lightning parameters and takes thorough analyses. This study shows the curves of the distribution on measuring parameters of the lightning supreme steepness and lightning peak current in Guilin of China, makes a good way to reasach the lightning and gives the real data.
