摘要
针对银盘水电厂自动化信号回路两起信号故障现象,分析了故障产生的原因,从理论上对故障原因进行了较深入的探讨,提出了正确接地、硬件隔离、软件抗干扰等消除干扰的措施。
Two signal failures in the automatic signal circuit in Yinpan Hydropower Station are investigated and the pos- sible interference causes are discussed theoretically. Some recommendation of prevention measurements are proposed, including the correct grounding, hardware insulation and software anti-interference, etc.
