摘要
为查找一起保护装置调试中发现的重合闸不正确动作原因,文中从现场保护装置实际动作分析入手,发现重合闸回路设计中将三相的TWJ短接而导致重合闸闭锁为直接原因,提出分相独立引入TWJ开入量的整改措施,保证重合闸正确动作。
To find out the reason of incorrecting motion occurring in protective devices debug of reclosing device, the thesis makes ananalysis of practical action process phenomenon in the field of protective devices. It finds out that the direct reason for the incorrect motion of reclosing device is reclosing locked. Resulted by shorting three-phase TWJ in circuit design of reclosing device, it puts forwardsthe rectification measure of exporting TWJ input by separation and independence ensuring. It corrects motion of reclosing device.
