4、正确选择接地点,完善接地系统

接地的目的通常有两个,其一为了,其二是为了抑制干扰。完善的接地系统是PLC控制系统抗电磁干扰的重要措施之一。

 

系统接地方式有:浮地方式、直接接地方式和电容接地三种方式。对PLC控制系统而言,它属高速低电平控制装置,应采用直接接地方式。由于信号电缆分布电容和输入装置滤波等的影响,装置之间的信号交换频率一般都低于1MHz,所以PLC控制系统接地线采用一点接地和串联一点接地方式。

集中布置的PLC系统适于并联一点接地方式,各装置的柜体中心接地点以单独的接地线引向接地极。如果装置间距较大,应采用串联一点接地方式。用一根大截面铜母线(或绝缘电缆)连接各装置的柜体中心接地点,然后将接地母线直接连接接地极。接地线采用截面大于22 mm2的铜导线,总母线使用截面大于60mm2的铜排。接地极的接地电阻小于2Ω,接地埋在距建筑物10 ~ 15m远处(或与控制器间不大于50m),而且PLC系统接地点与强电设备接地点相距10m以上。

 

信号源接地时,屏蔽层应在信号侧接地;不接地时,应在PLC侧接地;信号线中间有接头时,屏蔽层应牢固连接并进行绝缘处理,要避免多点接地;多个测点信号的屏蔽双绞线与多芯对绞总屏电缆连接时,各屏蔽层应相互连接好,并经绝缘处理。选择适当的接地处单点接点。
