| 摘 要： | 针对太原北郊DYYZII型自动气象站温度信号干扰的故障,结合该型自动站的信号传输方式和结构类型、设备接地网的分布形式、作用原理以及接地电阻测量值、外部环境对系统的影响程度评估等进行了综合分析。在常规处理方法不能彻底解决问题的情况下,运用多学科理论知识,对接地引线连接中由于金属氧化物作用对实际接地效果产生影响等方面的原因进行了详细的分析,同时提出了"接地电阻值符合要求不一定等于实际接地效果符合要求"的观点。在最终故障处理、验证过程中证明了金属氧化物对接地线的导电性能有直接的影响,为今后处理自动气象站温度信号干扰问题提供了一种新的分析思路和解决方法。

| Abstract: | Aiming at the troubleshooting of AWS temperature signal interference in the north suburbs of Taiyuan, a detailed analysis is made of the signal transmission mode and structure of the DYYZII automatic weather station,the distribution,working principles of the equipment grounding grid,and earthing resistance measurements, as well as the influence of metal oxides on actual grounding effectiveness in the grounding wire and the origin of the temperature sensor signal interference. The earthing resistance correspondence between requirements and actual grounding effect is discussed,and it is point out that meeting the requirements of grounding resistance values is not necessarily equal to meeting the requirements of the actual grounding effect. The troubleshooting and verification process indicates that there is direct impact of metal oxides on the conductivity of the grounding wire,which provides an analytical solution for future AWS temperature signal interference researches. |
