摘要
介绍了调度主站综合分析与智能告警模块及主站的事故分闸信号生成机制,指出事故总信号的生成原理有合后继电器常开接点与断路器跳闸位置继电器常开接点串接启动和保护动作启动,并阐述几种实际的应用现状,通过几起厂站跳闸事件主站未推出事故分闸信号的实例分析,得出了事故总信号的最优生成方法为合后继电器常开接点与断路器跳闸位置继电器常开接点串联的方式。
This paper introduces the comprehensive analysis and intelligent alarm module of the dispatching main station and the generating mechanism of the accident tripping signal of the main station, points out that the generating principle of the total accident signal includes the starting of KKJ's normally open contact in series with TWJ's normally open contact and the starting of protective action, and expounds several practical application situations. Through the case analysis of several factory trip events in which the main station did not launch the accident tripping signal, it is concluded that the optimal generating method of the total accident signal is the way that the normally open contacts of KKJ and TWJ are connected in series.
