大修后DCS系统如何上电,如何对DCS供电检查?
How to power on DCS system after overhaul and how to check DCS power supply?
DCS系统对供电质量有一定要求,大修后DCS上电应注意:
DCS system has certain requirements for power supply quality. After overhaul, attention should be paid to:
1、确认外部供电是否平稳,如检修期间电压不稳不要上电。
1. Confirm whether the external power supply is stable. If the voltage is unstable during maintenance, do not power on.
2、测试外部供电电压是否符合198V-242V要求。
2. Test whether the external power supply voltage meets the requirements of 198v-242v.
3、上电时按先总电源,再操作站,控制柜,外配柜顺序上电(断电则相反)。
3. Power on according to the sequence of main power supply, then operation station, control cabinet and external distribution cabinet (power failure is the opposite).

4、上电后对DCS卡件故障报警、电压故障报警、交换机和网络检查,对供电电压测试。
4. After power on, DCS card fault alarm, voltage fault alarm, switch and network inspection, power supply voltage test.
5、用万用表可检查DCS每个机笼的5V、24V电压,如低于5V、24V则不正常。如需对供电质量深入检查,需用示波器或电能质量分析仪检测分析。
5. The 5 V and 24 V voltage of each cage of DCs can be checked with a multimeter. If it is lower than 5 V and 24 V, it will be abnormal. If it is necessary to deeply inspect the power supply quality, the oscilloscope or power quality analyzer should be used for detection and analysis.
专家建议:系统维护负责人确认条件具备方可上电。应严格遵照上电步骤进行。
Expert suggestion: the system maintenance person in charge should confirm the conditions before power on. Power on procedures should be strictly followed.
