新一代天气雷达运行保障能力分析

为提高全国新一代天气雷达运行保障能力,选取了近5年多新一代天气雷达发生的3211个故障案例,从9个雷达分系统方面,按不同型号,对其发生的故障进行了分类统计分析,同时对导致故障的原因也进行了分析。结果表明:对于长期处在高电压工作状态下,且极易被烧坏的器件,以及运行时间较长的器件,要加强备件的备份,提高备件的可靠性、耐压性;要保持机房环境恒温、恒湿、防尘,使雷达能在良好的环境下工作;加强对电机碳刷碳粉尘的清理,定期地对汇流环进行维护、清洗,防止碳刷磨损,以减小被损坏的机会,以及对长时间在高、低温环境下运转的机械结构器件定期维护,以提高运动部件的可靠性;还要重点保证电力、雷达与外界通信畅通,使资料能够正常上传。

Investigation on Capability of CINRAD Radar Operational Security

A total of 3211 fault cases of Doppler weather radar of various models in recent 5 years are classified and analyzed for 9 radar subsystems. The results indicate that it is necessary for these that work under high voltage for a long time and are vulnerable, to burnout to strengthen the backup of spare parts and improve the reliability of these spare parts and to improve the reliability and resistance to pressure. Moreover, the machine room environment should have constant temperature and humidity, as well as dust proof to keep radar operating normally. It is also important to clean carbon dusts in the motor and maintain and clean the collector ring to prevent carbon brush abrasion and damage. Meanwhile, regular maintenance of the mechanical devices under high/low temperature environment for a long time is also needed in order to improve the reliability of moving parts. The power supply and data communication with external users are also important.
