Study on the Lightning Protection Differentiation Technology of Power Distribution Lines

Abstract

With the continuous improvement of China’s economy, the current construction of China’s power grid has been continuously optimized and improved, and the structure of the power system has become more professional and advanced. At the same time, the operation of distribution and transmission lines has become more complicated, which also poses new requirements and challenges for the operation management and maintenance of daily distribution and transmission lines. Therefore, this article will focus on the daily operation and maintenance measures of distribution and transmission lines. This article analyzes the various faults in the operation of daily distribution and transmission lines, calculates the lightning strike rate based on the topography of the line, and finds the line. The lightning protection point is weak. Then propose feasible measures to promote the operation management and maintenance work. Based on the research and summary of the operation mode of the distribution line system, this paper points out the power distribution line maintenance technology commonly used in the current system operation, and on this basis, explores the construction method of the lightning protection technology system. So that the security level of the entire system can be maximized.
