在选择设备时,首先要选择有较高抗干扰能力的产品,其包括了电磁兼容性(EMC),尤其是抗外部干扰能力,如采用浮地技术、隔离性能好的PLC系统;其次还应了解生产厂给出的抗干扰指标,如共模拟制比、差模拟制比,耐压能力、允许在多大电场强度和多高频率的磁场强度环境中工作;另外是靠考查其在类似工作中的应用实绩。在选择国外进口产品要注意:我国是采用220V高内阻电网制式,而欧美地区是110V低内阻电网。由于我国电网内阻大,零点电位漂移大,地电位变化大,工业企业现场的电磁干扰至少要比欧美地区高4倍以上,对系统抗干扰性能要求更高,在国外能正常工作的PLC产品在国内工业就不一定能可靠运行,这就要在采用国外产品时,按我国的标准(GB/T13926)合理选择。
2综合抗干扰设计
主要考虑来自系统外部的几种如果抑制措施。主要内容包括:对PLC系统及外引线进行屏蔽以防空间辐射电磁干扰;对外引线进行隔离、滤波,特别是原理动力电缆,分层布置,以防通过外引线引入传导电磁干扰;正确设计接地点和接地装置,完善接地系统。另外还必须利用软件手段,进一步提高系统的安全可靠性。
