摘要
贵州地处云贵高原东侧,属典型的喀斯特地貌发育区域,受地形变化影响形成的立体气候特征明显,造成境内雷暴活动复杂多变。2020年06月,位于贵州省贵阳市花溪区青岩镇石门洞村的贵州某建设工程有限公司遭受雷击,其商砼站主搅拌楼及中控室生产电器被击坏不能工作,造成严重的经济损失。本文对该地区雷电数据分析,通过查阅雷电监测记录,发现雷电危害主要为直击危害、感应危害、电波入侵以及地电位反击。根据现场勘测及结合三维雷电监测系统资料,对本次雷击事故发生原因分析,建议通过接闪器整改、防雷电感应整改、防雷电波侵入整改、接地等电位整改、架空输电线路整改来减少雷电造成的影响,降低雷击事故的发生概率。
Guizhou is located in the east of the Yunnan-Guizhou Plateau and belongs to a typical karst landform development area.The three-dimensional climate characteristics formed by the impact of terrain changes are obvious, resulting in complex and changeable thunderstorm activities in the territory. In June 2020, a Guizhou Construction Engineering Co., Ltd. located in Shimandong Village, Qingyan Town, Huaxi District, Guiyang City, Guizhou Province, was struck by lightning, and its main mixing building and central control room production electrical equipment in the commercial concrete station were damaged and could not work, causing serious economic losses.Based on the analysis of lightning data in this area and the review of lightning monitoring records, it is found that lightning hazards mainly include direct strike hazards, inductive hazards, radio wave invasion and ground potential counterattack. According to the site survey and combined with the data of three-dimensional lightning monitoring system, the causes of this lightning accident are analyzed, and it is suggested to reduce the impact of lightning and reduce the probability of lightning accident through the rectification of lightning arrester,lightning induction, lightning wave invasion, grounding equipotential and overhead transmission line.
