摘要
介绍备自投装置闭锁原理,分析备自投装置在典型接线方式下的动作逻辑及闭锁方案配置,并结合现场实际,对备自投跳合闸回路进行说明,以保证备自投装置正确动作。
The action logic and locking scheme configuration of automatic back-up switching device under typical wiring were analyzed based on locking principle of the automatic back-up switching device.According to the actual situation,the trip and close circuit was introduced to ensure the actual correct action of the device.
