摘　　要：多年来的运行数据表明南阳油田供电线路现有的绝缘配合方案存在很多薄弱环节,在油田生产过程中经常发生线路闪络和开关跳闸事故。针对南阳油田供电线路存在的绝缘薄弱环节,提出了南阳油田供电线路绝缘配合的优化方案。采用新方案油田供电线路绝缘强度得到加强,供电线路抗过电压能力得到很大提高,基本实现了油田电网“全天候”运行的目标。Many years operating data showe that there are many weak links in existing insulation coordinating scheme of power supply lines of Nanyang Oilfield. Flashover of transmission lines and tripping accidents of switchgears were of frequent occurrence during production process. Therefore an optimized insulation coordinating scheme for the power supply lines was developed. With the new scheme, the insulating ability was strengthened and the anti-overvoltage capacity was enhanced; thus the goal of ＂ operating in all weathers＂ for the oilfield power network was achieved.
