中文摘要: 简要介绍了某型燃气轮机振动监测系统的结构组成及其工作原理,通过对振动异常现象分析、试验, 排除其他因素的可能性,确定干扰来源于电容性耦合噪声。采取切断耦合途径方式,将电缆屏蔽层重新接地,加大噪声导体与受感应导体之间距离,有效消除振动干扰信号,为类似降噪除噪处理提供参考。
Abstract:The structure and working principle of a certain type of gas turbine vibration monitoring system are briefly introduced, through the analysis of abnormal vibration phenomena and experimental verification, the possibility of other factors is excluded, and it is determined that the interference comes from capacitive coupling noise. By cutting off the coupling, re-grounding the cable shield and increasing the distance between the noise conductor and the induced conductor, the vibration interference signal is electively eliminated, which can be used as a reference for similar noise reduction and noise reduction processing.
