石化企业配电网防雷措施浅析

摘要

Distribution network was the important component of transmission and distribution system for petrochemical enterprise.The lightning over -voltages would make the distribution line trip and then lead to the power supply interruptions , which often caused serious harm to petrochemical production safety , even resulted in serious injury , economic losses and social impacts.In order to ensure the safety and reliability service of distribution network and to reduce stroke-incidence rate of the electric line , integrated measures must be taken to prevent the harm of the lightning over-voltages and improve the reliability of the power supply system.%配电网是石化企业输配电系统的重要组成部分，雷电过电压会使配电线路跳闸进而导致供电中断事件，这往往给石化企业的安全生产造成严重危害，甚至造成严重的人员伤害、经济损失以及社会影响。为确保配电网安全、可靠运行并有效的降低线路雷击跳闸率，需采取综合性措施以防止雷电过电压的危害，提高供电的可靠性。
