With the development of national economy and the growing demand for electrical supply, the security of electricity production has become increasingly prominent. For the transmission lines, lightning trip has been a high-voltage transmission lines of the important factors in supply reliability. Activities due to atmospheric lightning randomness and complexity of the transmission lines on the world's understanding of Lightning there are still many unknown elements. Effective lightning protection measures taken to improve the high-voltage line lightning effect, the safe operation of power systems will be of great significance.This papers generated from the lightning theory, hazard, analyzes the different modes of lightning factors and restrictions to a Zhejiang 220kV four high-voltage transmission lines with the tower as an example, consider using a point of order method, electrical geometric model (EGM) calculated Principles such as computing, analysis tools, focusing on the trip around the strike rate, counter-trip rate is calculated by getting the total lightning trip rate calculation results of the four-circuit transmission line tower lightning with the effect of the amount of analysis. In the case of different types of lightning, as the basis to calculate the results for further analysis and verification, the corresponding proposals for the future use of the results to the four high-voltage transmission lines with the tower of the construction of lightning protection provide the basis for further research will in the future Lightning Protection for High Voltage Transmission Line and the proposed improvements of mine has a general theoretical significance.
