摘要
根据500kV阳淮输电系统切机传输回路运行原理,通过对运行情况的分析,对传输回路中转发接点潜在的缺陷提出合理的改造方案,制定切实可行的措施,解决了设备存在的问题,消除了系统隐患,防止误切机信号的传递,确保切机传输回路的安全可靠,提高了电力线载波通道的运行可靠性。
According to the operating principles of generator tripping channels of the 500 kV Yanghuai transmission system,reasonable modification scheme was presented against the potential defects of retransmission junctions in the transmission loops through analysis of the operation situations. Practical measures were established which solved the existing problems of equipments, removed the hidden trouble of the system,prevented the transportation of mis-signals for generator tripping, ensured the safety and reliability of tripping channels and increased the operating reliability of power line cartier channels.
