| Abstract: | With the rapid development of economic, the requirements for the stability and continuous operation of medium voltage distribution network by the business electricity and residential electricity consumption are more and more high. The paper analyzes the factors on the trip of lightning rate of medium voltage distribution network line, points out that we should consider the factor of altitude in analyzing the cloud-to-ground lightning of medium voltage distribution network, proposes the concept of correction coefficient, and obtains the calculation formula of the correction coefficient based on the data analysis. At last, considering altitude factors, this article puts forward the lightning protection scheme for medium voltage distribution lines in intensive lightning region. |
