摘要
对电缆与架空线路连接的薄弱环节进行了分析,提出了限制雷电侵入波值和限制护层过电压的措施;改进设计引流导线与电缆终端头的连接金具,合理选择镀层,可以有效降低接触电阻,提高电缆与架空连接的电气性能;使用预绞丝耐张金具,可以比传统方案减少60%的电接触次数,同时施工简便,用于技改工程中,可缩短停电时间。
The cable and weaknesses overhead lines connected analyzed, proposed measures to limit the lightning invasion wave values and limits sheath overvoltage; improved design drainage wire and cable terminal head connector fittings, a reasonable choice coating, can effectively reduce contact resistance, improved electrical performance overhead cables and connections; using preformed wire strain fittings can be 60% less than traditional solutions electrical contact times, while the construction is simple, for technological transformation projects,you can shorten the outage time.
