商品描述
前言

前 言我国是风能资源比较丰富的区域,风能能够造福人类,使人类获取能源,此外,也对人们生产生活带来危害。以输变电设备为例,“风害”能够造成输电线路风偏跳闸、金具磨损断裂、导地线断股断线、塔材变形,严重的情况下能够造成杆塔倒塌的恶性事故。输变电设备风害地区分布广泛,以西北、东北和沿海等区域尤为显著,这些地区长期存在着极端风害,给输变电设备建设、运行维护和检测检修等工作带来了巨大的难题,同样也给电力设备的安全运行带来严重危害。本书作者以多年来的新疆典型案例为例,结合其他区域的输变电风害案例,整理并总结了输变电设备风害典型案例,在此基础上,提出了相关应对措施,为相关专业人员提供重要技术参考。国网新疆电力有限公司和湖北大学深度联合,依托疆电外送的特高压输电工程,环绕塔克拉玛干沙漠、穿越西天山等多条750kV 输变电工程,以及其他区域的风区线路,从实际输变电设备发生的各种风害故障出发,研究了输变电设备风害故障发生的机理,总结了输变电设备发生风害的规律及特点,从实际工程中发生的典型案例进行了故障原因分析并提出了相应改造防范措施。本书由董新胜、张陵、张博、王建和黄浩共同完成,李岳彬教授和楼平教授负责审稿和校核。共分为七章,第一章由张陵、杜平、董新胜、金铭、赵普志和付豪执笔,介绍了风的基本概念、风场实测和分析、场址长期风速资料分析;第二章由董新胜、黄浩、王立福、杨洋、郭克竹、赵蓂冠和李孟执笔,详细介绍了导线风偏跳闸机理和案例;第三章由董新胜、朱咏明、王奇、杨定乾、周利兵和刘举成执笔,着重于电力金具磨损的机理、案例和应对策略;第四章由董新胜、张博、刘威、董仲凯、曾东、胡帅和王红霞执笔,着重于导线断股断线的机理、案例和应对措施;第五章由董新胜、王建、张陵、庄文兵、、马永录和郑子梁执笔,介绍了输电杆塔风害故障机理、案例和应对措施;第六章由董新胜、黄浩、赵蓂冠、李孟、刘威、董仲凯和张力夫执笔,介绍了避雷针风害故障机理、案例和应对措施;第七章由张陵、张博、董新胜、王建、金铭、赵普志、付豪、张力夫和张小军执笔,介绍了其他变电设备比风害故障机理、案例和应对措施。中国电力科学研究院邬雄教授、国网电力科学研究院聂德鑫研究员和湖北大学胡永明教授提出了宝贵建议,在此一并表示感谢。本专著介绍的案例、方法、技术、装置和标准适用于整个电力系统,适合电力设备防灾减灾科技人员参考,也适用电力设备运维检修技术人员,可为从事风害地区输变电工程设计、运行维护等专业的科研与生产人员提供参考,也可以作为相关专业教职人员、研究人员的参考资料。由于水平和经验有限,书中难免有缺点或错误,敬请读者批评指正。著 者2022 年4 月
