摘要
为了提升小浪底水利枢纽坝用电10 kV系统智能化水平,增设了坝用电10 kV系统备自投装置自复功能并完成了相应控制回路改造,优化了备自投和进线保护配合逻辑,实现了备自投自复、手动分闸闭锁备自投和进线保护闭锁备自投功能。
In order to improve the intelligence of 10 kV dam distribution network in Xiaolangdi project,the automatic recovery function of 10 kV dam power system backup automatic switching device is added,and the corresponding control circuit transformation is completed.The coordination logic of backup automatic switching and incoming line protection is optimized.The functions of automatic switch on and automatic recovery,manual switch off blocking automatic switch on and incoming line protection blocking automatic switch on are realized.
