中文摘要: 轴角箱是CINRAD/SA雷达天伺系统中联系数字控制电路与机械电机的关键环节,它的故障造 成雷达系统报警不断,方位环节故障将导致终端产品出现蜘蛛网状回波,俯仰环节故障则导 致系统无法工作。为了降低轴角箱故障造成对雷达正常运行的影响,通过对广州雷达站前后 出现的5次同类故障的综合分析,总结得出问题多出现在轴角箱的激磁电压环节,原因是由 于天线罩温度高、湿度大,导致部分元器件出现性能退化。针对薄弱环节,采取相应的改进 措施之后,问题得以彻底解决。

Abstract:The encoder is a key part of servo system in CINRAD/SA radar, which contacts dig ital control unit with mechanism of the pedestal. While failure happens in azimu th loop, it will cause ananeose echo in products, and while fault happens in ele vation loop, it will cause INOP about radar system. Five faults about the encode r were analyzed. It discovered that the faults mainly come from the magnetizatio n voltage. When the temperature and humidity are too high in the antenna dome, partial parts will be degenerated. The problem will be throughout resolved after some measures are taken.
