2、tors7、附录 16AppendixDCS复原通电调试方案一、第一步 DCS配电柜受电：应该先断开电气侧 UPS的电源开关（根据设计情况，有的两路用两套 UPS,有的用一套UPS）、DCS配电柜的总开关及至 DCS 各控制柜的小空气开关。 由电建单位电气专业检查电 气来两路电源的线路相间绝缘及总开关对地绝缘 （用摇表）,符合要求后先合一 路UPS电源，在DCS配电柜内测量电源品质，包括电压及频率，没有问题后 合上配电柜内总开关,测量总开关的出口（输出电压）是否满足要求,若没有 问题再把 DCS 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 D

3、CS 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

4、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。 - Y+ O* |（ C. O- t+ e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 1 $ ?. p/ A; B- r$ o, I L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

5、缘，控制柜的信号地及安全地的接地电阻，电子 间内的温度湿度等， 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。 3 ?0 & o8 B; % v） S/ T;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
