兴仁换流站站用电10kV系统由3回电源供电,第1回电源经500/10kV变压器降压、第2回电源经110/10kV变压器降压、第3回电源经35/10kV变压器降压后,通过10kV电缆送到控制楼一楼的10kV母线,经10kV母线分配后由10/0.4kV干式变压器送至各400V母线。该站用电系统采用WBT-821微机型备自投装置,经精心整定配合,并解决了存在的问题,满足设计要求,当工作电源消失时,能将其迅速地切换到备用电源,保证重要负荷的正常运行。
Xingren converter station power 10kV system powered by three back to the first back to power by 500 / 10kV transformer step-down, the second back to power by 110 / 10kV transformer step-down, the first three by 35 / 10kV transformer power transformer After pressing, it is sent to the 10kV bus on the first floor of the control building through a 10kV cable and is sent to each 400V bus by a 10 / 0.4kV dry-type transformer after being distributed by a 10kV bus. The station power system using WBT-821 microcomputer-based self-throwing device, carefully set to match and solve the existing problems to meet the design requirements, when the power disappears, it can quickly switch to the standby power supply, ensure Important load of normal operation.
