| 摘 要： | 为保证对重要用户可靠供电,在终端变电站中常配有备自投装置.但若备自投方案中存在缺陷,则可能因备自投误动而导致全站失电.结合禄口变35 kV备自投误动案例,分析了误动原因,并提出合理建议,即采用双节点替代单节点遥信、或采用开关辅助接点信号来判别开关位置,可有效避免因跳(合)闸线圈烧坏而诱发的备自投误动.

| Abstract: | In order to ensure the reliable power supply for VIP customers,busbar automatic transfer equipments are generally used in terminal substations.If the busbar automatic transfer switch is not configured properly,its mal-operation may cause the whole substation power-off.After analyzing the reasons for mal-operation accident occurred in the Lukou substation,it is brought forward that using double-node remote communication to replace the single-node,or using the auxiliary node of breakers to distinguish the swi... |
