摘要
在对直流电源系统隔离开关位置、回路电流及电压差等实时监测的基础上,研究隔离开关两侧压差判断法、回路电流判断法及辅助触点判断法,提出采用上述方式进行组合判断分析,实现对直流电源系统运行方式和隔离开关状态的实时在线监测与评估诊断,发现潜在故障隐患并及时预警。
On the basis of real-time monitoring on position of the isolating switch of DC power source system, loop current and voltage difference, this paper studies judgment method of voltage difference on both sides of the isolating switch, loop current judgment method and assistant contact judgment method. It also proposes to use all the above methods for combina-torial analysis so as to realize real-time online monitoring and assessment diagnosis on operation mode of the DC power source system and state of the isolating switch as well as discover potential fault hidden dangers and make early warning timeiy.
