Prevention and Protective Measures against EMI of UMT Substation

介绍了城市轨道交通变电所电磁干扰的危害,分析了轨道交通系统电磁干扰的产生源。从变电所设备的设计、制造、组装及其安装现场等方面提出解决系统抗干扰的有效措施。重点介绍了轨道交通变电所微机监控系统的抗干扰措施,从而达到抑制干扰的目的。

This paper introduces the harm of EMI （electromagnatic interference） on UMT substation, analyses its causes and the basic preventive and protective measures for the equipment in substation. The effective measures could be displayed in several aspects, such as the design, the production, and the assembly of the equipment in substation. Here the anti - EMI measures of UMT monitoring system are disscussed,which will play an important part in the stable operation of UMT substation against EMI.
