摘要
计算了葛上±５００ｋＶ直流输电工程上海直流接地极的溢流分布，指出了在引流电缆和馈电钢棒连接处溢流的过分集中是导致原上海直流接地极烧毁故障的主要原因之一。为此，合理选择引流钢棒的布置是延长上海直流接地极运行寿命的有效方法。
In this paper the current distribution of original and present Shanghai DC ground electrodes are calculated. It is pointed out that current over accumulation at the connected positions between feeder cables and electrode steel rods was one of the main reasons that cause original Shanghai DC
