本文对Alcan Smelters and Chemicals股份有限公司的魁北克动力系统中装有单相自动重合闸和远方的跳闸的双回345kv输电线路作了叙述。报告和评论了重合闸装置工作13年来的性能,讨论了地网和架空避雷线对重合闸和雷电的影响。结果表明,单相重合闸在双回路中任何一回和双回线运行时,对维持系统稳定是成功的。 This article describes the double-circuit 345 kV transmission line with single-phase automatic reclosure and remote tripping in the Quebec power system of Alcan Smelters and Chemicals GmbH. Reported and commented on the performance of the reclosing device for 13 years of operation, and discussed the effects of the ground network and overhead lightning conductors on reclosing and lightning. The results show that single-phase reclosing is successful in maintaining the stability of the system when it is operated in any of the double loops and double loops.
