广州抽水蓄能电站500kV充油电缆运行监测与分析

Supervision to an 500kV oil-filled Cable Operating in GuangZhou Pumped Storage Station

广州抽水蓄能电站两回500kV高落差充油电缆,是由法国引进的,自1993年3月投入运行以来,经516天的1监测,取得了许多数据。据此,进行了电缆特性参数的分析比较,电缆载流量与芯线温度的关系,SF_(6)电缆终端的漏油监测与分析以及电缆真空绝缘油系统的运行分析等等。可供运行与工程设计人员参考。

Two line 500kV large height difference oil-filled cables, put into operation in March 1993, are bought from France. Five hundred and sixteen days monitoring has made on the relation between load current and temperature of the conductor, oil leakage at the terminal of this SF6 cable, and the operating status of vaccum insulation oil system and many analysis results that will be useful for operation and engineering design are gained.
