摘要
传统防雷系统存在防雷水平不佳,花费过高等问题,为此,设计一种土壤电阻率影响下输电杆塔线路自主防雷保护系统。结合信息中心机房设计系统的硬件部分,详细描述系统硬件的设计原则。由于土壤电阻率影响下输电杆塔线路的杆塔横担接地,采用延续伸长接地体连接各个基杆塔的接地装置,为输电杆塔线路自主防雷提供一条低阻通道,有效预防输电杆塔线路遭受雷击。仿真实验结果表明,所设计系统能够有效防止雷电攻击,同时为后续的研究奠定坚实的基础。
The traditional lightning protection system has the problems of low lightning protection level and high cost.Therefore,an independent lightning protection system for transmission tower line under the influence of soil resistivity is designed.Combined with the hardware part of the computer room design system of the information center,the design principle of the system hardware is described in detail.Due to the influence of soil resistivity,the cross arm of transmission tower line is grounded.The continuous extension grounding body is used to connect the grounding device of each base tower,which provides a low resistance channel for independent lightning protection of transmission tower line and effectively prevents transmission tower line from being struck by lightning.The simulation results show that the designed system can effectively prevent lightning attack and lay a solid foundation for future research.
