该文基于一次强对流天气中三明CINRAD/SA雷达天线动态错误故障,分析伺服系统工作特点、数据指标、电路构成、故障原因,遵循先易后难、向上寻错的原则,排查电机、汇流环、电缆接口等伺服系统天线机械部分,最终锁定故障原因为天线策略外过冲至超限范围外带来电机不工作,可为CINRAD/SA雷达保障提供参考。
Based on the dynamic error of Sanming CINRAD / SA radar antenna in a severe convective weather, this paper analyzes the characteristics of the servo system, data indicators, circuit configuration, cause of failure, follow the principle of easy first, rearward and wrong. , The cable interface and other servo system antenna mechanical parts, the ultimate cause of locking failure for overshoot outside the antenna strategy to bring the motor does not work outside the limits, CINRAD / SA radar protection can provide a reference.
