佛山电网500 kV砚西甲、乙线运行分析

根据佛山供电局500 kV砚西甲、乙线送电线路的运行维护工作,对线路故障、绝缘子运行情况、接地电阻和西江大跨越等情况进行分析,明确了运行维护应根据不同区段采取相应措施,在设计过程中应有足够裕度。并提出,杆塔接地电阻宜提倡充分利用自然接地,对线路建议安装振动实时监测系统。

Operation Analysis of Foshan Grid 500 kV Yanxi A and B Lines

Based on Foshan Power Supply Bureau's operation and maintenance works on 500 kV Yanxi A and B Lines,the line faults,insulator operating conditions,grounding resistance,and Xijian River large crossing,etc.,are analyzed.It is clarified that proper operation and maintenance measures should be taken according to conditions at different sections,there are must be enough margins in the design.It is also suggested that natural grounding should be used as tower grounding resistance,and real time vibration monitoring system should be equipped for the lines.
