5、接地连接方法:
仪表及控制系统保护接地的各接地分干线应汇接到保护接地汇总板,再由保护接地汇总板经接地干线接到总接地板上;
仪表及控制系统工作接地的各接地分干线应分别接到工作接地汇总板,再由
工作接地汇总板经两根单独的工作接地干线连接到接地总接地板;
仪表信号公共点接地、DCS、PLC、SIS等的非隔离输入的接地,均应分别单独接到接地连接端子排或工作接地汇流排上,然后通过接地分干线接到工作接地
汇总板;
当有多根信号屏蔽电缆的屏蔽层接地时,宜先将各信号屏蔽电缆的屏蔽层汇接到工作接地汇流排,再经工作接地分干线接到工作接地汇总板;
直流电源的负端必须接到本机柜的工作接地汇流排,不设工作接地汇流排的情况应经工作接地分干线接到工作接地汇总板;
接地干线长度若超过10米或周围有强磁场设备,应采取屏蔽措施,将接地干线穿钢管保护,钢管间连为一体;或采用屏蔽电缆,钢管或屏蔽电缆的屏蔽层应单端接地。
若接地干线在室外走线并距离超过10米,应采用双层屏蔽,内层单点接地,外层两端接地,或每隔30米设一个接地点,以防止雷电电磁脉冲的干扰。
