Installed on the outside of the tower above the instrument and equipment vulnerable to lightning strike, lightning protection facilities are crucial. On the basis of the basic requirements of the lightning protection standards, this paper explores how to improve the lightning protection methods, improve the lightning protection performance of lightning protection facilities, and reduce the probability of lightning strike. Based on the analysis on the example of a large number of lightning, lightning from the pulse spectrum characteristics and electromagnetic compatibility principle indepth analysis of lightning details for lightning causes, can weaken or blocking lightning impulse characteristic of inductance capacitance conductor based on the distributions presented by a circuitous strategy change device set point discharge from the main path, the barrier effect of inductance adjustment of shunt, the solution to reduce the direct impact of lightning current on the equipment. In view of the low cost engineering of lightning protection has been built system, put forward the “short circuitous strategy” for the new system, put forward the "long circuitous strategy" lightning protection solutions, and gives the concrete design method, improved the traditional practice of lightning protection. After nearly twenty years of statistical analysis, the results show that the circuitous strategy of lightning protection method is more practical, effective and easy to implement.
