摘要
雷击是影响地震观测仪器正常运行的主要因素之一,由于地震前兆仪器种类多,观测原理不尽相同,加上台站自身布局和所处地区气候的不同,使得前兆台站综合防雷改造的效果提升必须依靠有针对性的方案设计。文章在介绍江苏地区前兆台站综合防雷改造的基础上,对现有综合防雷技术的关键点分别进行了阐述,并以盱眙地震台的综合防雷改造作为案例进行分析,阐述了防雷效能提升的技术途径。
Lightning is the most important factor to influence the normal operation of seismic observation instrument. The operational efficiency of lightning protection for seismic station must rely on a pertinence scheme. Since there are many kinds of earthquake precursor instruments, the observation principle is different from the each other. The layout of each seismic station and the climate in the area are also not same. This paper explains the key points of the current technology of lightning protection according to the basis of the experience of lightning protection of earth- quake precursor station in Jiangsu province. Then we take the work of lightning protection in Xuyi Seismic Station as a case analysis and elaborate the technical approach of the efficiency improvement on the lightning protection.
