电气设备防雷工程设计探讨

雷电天气常对电气、电子系统造成灾害.以威海市驾驶员电子桩考场遭受雷击事故为例,对电子桩的结构、线路的设置方式、雷电防护的措施等情况进行了调查分析,在雷击风险评估的基础上,结合规范和考场特点,设计了该考场的防雷方案,重点探讨了直击雷防护和感应雷防护的设计,对考场内信号线路系统、办公楼内监控系统、控制室接地系统进行了合理的设计,从而对电气系统防雷工程设计进行了探讨,为电气系统防雷工程设计提供一些可靠的参考.

Lightning Protection Engineering Design of Electrical Systems

Lightning weather often induces hazards to electrical systems. A lightning induced electrical system accident is studied in detail, which happened at the electronic pile examination spot for car drivers in Weihai. The structure of the electronic piles, the layout of lines, and the measures of lightning protection are investigated. Based on the assessment of lightning risk, combined with the safety standards and the features of the examination spot, the design of lightning protection scheme for the electronic pile examination spot is given. The direct lightning protection and induction lightning protection design are discussed emphatically. The examination spot signal lines within the system, the office building monitoring system, the control room grounding system are reasonably designed. The lightning protection design of electrical systems is also discussed, and the results can be used as references for electrical system lightning protection design.
