太钢地震台避雷设施的布设及效果

在强雷电活动季节，地震观测仪器常受到雷电的侵害，太原钢铁（集团）有限公司地震台为解决这一问题采取了系统区域避雷的措施－在观测区域架设网状式避雷针塔，在观测设备的供电系统进行防电磁感应雷击的多级避雷，在观测信号系统串接避雷器等，避雷装置运行1a的结果表明，在遭受多次雷电时，该装置发挥了很好的避雷作用，保证了仪器的正常运转，得出该装置避雷效果较好的结论。

Installation and Effect ofLightning Arrester in Seismic Station of Taiyuan Iron and Steel Corporation

The seismic observation instruments are injured by the thunderbolt during the strong thunderbolt activity season.In order to avoid the problem，the Seismic Station of Taiyuan Iron and Steel Corporation adopted the measure of the lightning arrester in the systematic region which set up the netted lightning rod tower in the observation region，set up the multigrade lightning arrester protected the thunderstroke of the electromagnetic induction in the power supply system of the observation equipments，and series connected the lightning arrester to the observational signal system.The run situation of 1a suggested that the arrester set played best lightning protect role in the thunderstrokes，and ensured the norma l running of the observation instruments.
