摘要
由于泵站内干扰源众多、设备复杂、干扰频率范围宽．为使泵站微机数据采集系统可靠运行，必须采取防干扰或抑制措施。系统地描述了泵站微机数据采集系统的接地要求．提出增强系统抗干扰能力和电磁兼容性的实施方案．归纳出具体施工过程中切实可行的接地措施。
The earthing requirements of data acquisition system for pumping stations are described systematically. The implementation scheme for strengthening the ability of anti jamming and electtomagnetic commpatibility is presented. The practical and available earthing measures are summed up from the practical construction process. [
