地震台站的防雷技术探讨
|
摘要
雷电灾害主要发生在天线、电源线、控制线等外部部位,以及通过相关线路和机壳感应进入设备内部。常见故障为损坏天线、架空明线及设备元器件。随着电脑及通讯设备在地震台站的广泛应用,雷电造成的危害越来越严重。采用合理的预防措施可以防止灾害发生或减轻灾害损失。
The thunder calamities usually happened on outer components such as antenna,power line,pilot wire and etc.,or entered into equipment inside through interrelated circuit and envelope induction.The typical fault was the damages from antenna,aerial line,and equipment components.With the wide applications of computers and communication equipments in seismic station,the harm from the thunder calamities had become much more fearful.The thunder calamities can be prevented or mitigated,only adopted the rational precautionary measures.
