1、 本科生毕业论文 论文题目 110 可变电站的防雷设计 2013 年 04 月 12 2 110KV110KV 变电站的防雷设计变电站的防雷设计 摘 要 变电所是电力系统重要组成部分，是电网传输电能的核心。一旦变电所遭受雷击，可 能直接造成电网的瓦解，造成大面积的停电，给社会的安全和稳定以及人民的生活带来极 大的负面影响，这就要求变电所的防雷措施必须十分可靠。 高压变电站是供配电系统的中心枢纽，其正常运行直接关系到供电系统的连续性、可 靠性和安全性。雷电对于变电站高压供配电以及由耐低压且传输信号为毫伏安级的弱电设 备组成的控制、保护信息系统的危害较大。 本设计针对 110kV 变电站的防雷进行

2、分析及研究，指出了 110kV 变电站防雷的特点， 提出并解决了 110KV 变电站防雷应注意的一些问题和初步建议，从而防止雷电对控制、保 护系统等装置产生干扰、损害等故障，保证设备正常可靠运行。 本次设计通过研究变电站避雷针、避雷器的架设位置，加强了变电站防雷保护措施，提高 了变电站主要设备的耐雷水平，从而确定了 110KV 变电站防雷设计模型。 关键词：变电所，避雷器，防雷 Abstract Transformer station is not only an important part of electric power system, but also the core of ele

Some problems and preliminary suggestions about thunder prevention, to which attention must be paid, of 110kV transformer station, are raised here. The trouble like interference and damage to controlling-protecting system installations can be prevented so that the
