摘要 海南地处我国最南端,雷电活动极为强烈,绝缘水平较低的10kV配电线路极易因雷击跳闸,直接影响海南工农业生产生活用电。因此,有效提高10kV配电线路防雷性能评估水平与治理能力,对保证海南地区供电的稳定可靠十分重要。本文采用配电网差异化防雷技术开展海南强雷区10kV配电线路防雷综合治理研究,首先建立综合考虑雷电信息、线路结构及绝缘配置信息的雷击风险评估流程;然后选择雷害最为严重的典型配电线路开展逐基杆塔的精细化雷击风险评估;根据风险评估结果,结合配电网各种防雷措施特点,选择安装带间隙避雷器作为改造措施;最后依据改造杆塔范围和次序,制定两套线路防雷改造方案,并量化评估各套方案的预期效果。

Abstract:Lightning activity is very strong in Hainan, which is in the southernmost of China. Because of the low insulation level, 10kV distribution line is easily to occur lightning tripping. Therefore, in order to improve power supply stability and reliability, it is very important to improve the assessment level and rebuilding ability of lightning protection for distribution lines. This paper researches on comprehensive management of lightning protection for the transmission lines in strong lightning district of Hainan based on the technology of differentiated lightning protection. First, the process of lightning protection risk assessment based on lightning activities and line's structures is set up. Then the typical distribution line is selected and elaborate lightning protection risk assessment for each tower is carried out. According to assessment result, characteristics of lightning protection measures, arrester with gap is selected to be improvement measure. At last, based on the scope and sequence of lightning protection rebuilding, two rebuilding schemes have been formulated. And quantitativel evaluate the expected effect of each scheme.
