摘　　要：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,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。通过ATP仿真和实验结果表明,限陡避雷器的使用,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 lightning current steepness is one of important reasons of destruction. Based on the electromagnetic wave dispersion,the use of the ICP-impedance circuits lightning limiting its use in direct lightning stroke prevention Against thunderstorm devices to develop a new type of anti-inductance limits steep arrester, and apply electro-magnetic transient program ATP to simulate and the 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 for the electrical power system.
