大修後DCS係統如何上電,如何對DCS供電檢查?
How to power on DCS system after overhaul and how to check DCS power supply?
DCS係統對供電質量有一定要求,大修後DCS上電應注意:
DCS system has certain requirements for power supply quality. After overhaul, attention should be paid to:
1、確認外部供電是否平穩,如檢修期間電壓不穩不要上電。
1. Confirm whether the external power supply is stable. If the voltage is unstable during maintenance, do not power on.
2、測試外部供電電壓是否符合198V-242V要求。
2. Test whether the external power supply voltage meets the requirements of 198v-242v.
3、上電時按先總電源,再操作站,控製櫃,外配櫃順序上電(斷電則相反)。
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、上電後對DCS卡件故障報警、電壓故障報警、交換機和網絡檢查,對供電電壓測試。
4. After power on, DCS card fault alarm, voltage fault alarm, switch and network inspection, power supply voltage test.
5、用萬用表可檢查DCS每個機籠的5V、24V電壓,如低於5V、24V則不正常。如需對供電質量深入檢查,需用示波器或電能質量分析儀檢測分析。
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.
專家建議:係統維護負責人確認條件具備方可上電。應嚴格遵照上電步驟進行。
Expert suggestion: the system maintenance person in charge should confirm the conditions before power on. Power on procedures should be strictly followed.
