雷击是雷暴云与大地之间的放电,当雷电流从云中泄放到大地时,将对建筑物、构筑物及电子设备造成毁坏,由于造成雷击灾害的形式不同,雷电防护采取的措施也不同,HBCORS的雷电防护工作主要有2方面:一是观测墩防雷,通过在观测墩3m处安装避雷针,并通过引下线与接地装置连接,达到保护建筑物不受直接雷击的目的;二是系统防雷,在电路线、信号线及天馈线上穿接避雷器,并通过引下线与接地装置连接,一旦有雷电流侵入,能通过避雷器迅速泄入大地,从而保护电子设备不受损害。 更多还原

【Abstract】 Lightning is an atmospheric discharge of electricity accompanied by thunder,lightning strike are electrical discharges caused by lightning,direct lightning strike can cause severe damage to ground structure and electrical device.For protection of ground structure and electrical equipment from lightning strike,different method may have to employed.For ground structure(observation pillar),lightning rod will installed 3m away from observation pillar,high voltage current will channel away by groundi... 更多还原
