摘要
针对发生在500 kV长春合心变电站里的大面积220 kV线路保护装置出现“距离保护告警”的现象,经分析,认为应采用并接多个端子排的方式把电压母线N 600分配给各套保护和安全自动装置,直接从母线电压屏处通过电缆的方式取用电压公共母线N 600。
Aimed at the “distance protection alarm” in large area 220 kV line protection device of Hexin 500 kV substation, this paper considered that it should parallel in multi-terminal row to distribute every suit of protection and safety auto-device, and through cable to get the voltage common bus bar N600 directly from the bus bar voltage screen.
