3、CS 配电柜内总开关断开。用同样方法再检查电气来的另一路电源。两路都没有问题后，都合上，再检查DCS 配电柜内总开关的输出电压品质，没有问题后，电气送至DCS 配电柜成功。（如果有两路的话，也可能当前只有一路临时电源经过 UPS 送至 DCS 配电柜）二、第二步 各 I/O 控制柜受电：应该先检查各控制机柜的信号地及系统地的接地情况，并记录数据，检查 DCS 配电柜内各空开的单相对地绝缘及相间绝缘（用万用表量一下电阻即可），把所有 I/O 卡件拔出其浮空（以后根据试运进度选择逐个卡件投入运行，例如明天准备转引风机，线也接完了，量一下现场来的信号没有强电压及强电流后才可以投入卡件）。没有问题后逐
4、个控制机柜送电，也是先送一路，检查电源品质没问题且DPU状态指示灯显示正常后，断开再合另一路，没问题后再两路都合上，再检查双电源供电时的电源品质。三、第三步 各 MMI 上位机受电：也是先检查DCS 配电柜内空开绝缘及线路绝缘，没问题后先合一路再合另一路，最后两路都合上。四、第四步 网络交换机受电：同上。正常后在上位机查看网络状况是否正常。五、整个 DCS 系统所有部件都上电正常后(包括检查直流部分的供电及输出是否正常)，进行电源冗余试验及网络冗余试验六、受电过程中应记录各种数据，包括电气至DCS 配电柜的电源电压等品质，线路相间绝缘，总开关对地绝缘，控制柜的信号地及安全地的接地电阻，电子间内
5、的温度湿度等，将来写报告及存档用。包括检查 DCS 配电柜内各小空气开关的相间及对地绝缘（这个用2K2MG-E专业技术人员绩效管理与业务能力提升练习与答案万用表大体测量一下电阻即可），检查各控制柜内接地线与接地铜排连接是否紧密。七、组织分工要明确，包括调试所、电建单位、DCS 厂家、监理等单位，谁指挥谁操作谁监护都要明确，确保通讯联系畅通，一有问题马上能快速处理（一般问题不大，但现场首次受电也可能存在些不确定因素），包括两个专业热工与电气（电气只负责把两路合格电源送至 DCS 配电柜），要有可操作性比较强的受电方案步骤，受电前要进行详细的交底会议，明确各岗位职责，避免误操作。Commissio
