摘　　要：较大的雷电流陡度是雷电流产生破坏的重要原因之一。从电磁波弥散现象出发,改用电感型阻抗对闪电限流并将其运用在线路防直击雷上,研制一种新型的防直击雷装置——电感型限陡避雷器。ATP仿真和实验均表明,限陡避雷针的使用,能有效的降低雷电流陡度,降低塔顶电位。限陡避雷器为电力系统防雷又提供了一个新的手段。The relatively large lightning current steepness is one of the important causes of lightning destruction. Based on the electromagnetic wave dispersion, ICP-impedance circuits for lightning current limiting are used in prevention of direct lightning striking; a new type arrester for preventing direct lightning striking is developed： inductance limiting steepness arrester. ATP simulation and experiments indicate that inductance limiting steepness arrester can effectively reduce the lightning steepness and the voltage of tower top. Inductance limiting steepness arrester provides a new method of lightning protection for power system.
