摘要
避雷工作是一项较复杂的系统工程,在数字化台网的运行过程中,易县台的数字化地震前兆观测仪器(以后简称数字化仪器)连续数次因遭雷击而损坏,给台站工作和资料质量造成巨大损失。本文分析了造成雷击的原因,介绍了我台所采取的避雷方法。
Lightning prevention is a complex work. In the operation of past, the digital seismic precursor instruments have been damaged by lightning several times and it affected the quality of observational data greatly.
