摘    要:通过对全国已安装的新一代天气雷达雷击灾害的调查,并结合湖北省武汉、十堰、恩施三部天气雷达雷击事故的分析,揭示了其事故原因主要在于防雷设备安装不完善、部分配置设备安装不合理及施工过程中未采取临时防雷措施。在此基础上,指出了新一代天气雷达防雷中的几个问题:一是雷达站应按行业标准对其采取综合防雷措施;二是对新一代天气雷达楼应科学划分雷电防护区并对各区采取全面的防雷措施;三是雷达辅助配置设备航空障碍灯不宜安装在天线罩顶端;四是在雷达安装施工期间必须增设临时防雷措施。

关 键 词:天气雷达  雷击灾害  天线罩  雷区划分  防雷措施

Abstract:Through investigation on lightning stroke accidents to NEXRAD built up in our country, especially by analyzing the accidents at the three radar stations in Wuhan, Shiyan and Enshi of Hubei province, causes of the lightning stroke accidents are revealed as the faultiness of lightning-prevention facility installation, the illogicality of some lightning-prevention fittings or the ignorance of temporal lightning-prevention methods during the construction. Further, some problems in NEXRAD lightning-prevention are pointed out as follows: firstly, synthetic lightning-prevention measurements according with the trade standard should be taken for radar stations; secondly, lightning-field division should be done for NEXRAD building and the complete measurements should be adopted for every field; thirdly, aviation obstruction lamp as lightning-prevention assistant fitting should not be fixed on the top of radome; fourthly, temporal lighting-prevention measurements should be added during radar construction period.
Keywords:Weather radar  Lightning stroke accident  Radome  Lightning-field division  Lightning-prevention method
