摘要
针对某500 kV新建智能变电站低压侧总开关事故总信号的生成方式进行研究,指出断路器智能终端二次回路设计及监控后台信号名称设置存在的问题,分析了其对现场电力设备运行和检修操作造成的影响。提出了对断路器智能终端二次回路结构及监控后台低压侧总开关事故总信号合成方式的改进策略,为断路器操作回路设计优化、信号设置以及现场基建验收提供经验。
This paper studies the generation method of the integrated accident signal of the main switch on the low voltage side of a certain newly built 500 kV intelligent substation,then points out the problems existing in designing the secondary circuit of the circuit breaker intelligent terminal and setting the monitoring backstage signal name,and also analyzes their influence on the operation and maintenance of on-site electric power equipment.Finally,the paper proposes the improvement strategy for the secondary circuit structure of the intelligent terminal of circuit breaker and the synthesizing method of the low-voltage side main switch’s integrated accident signal in the monitoring backstage,thus providing experience for the operation circuit design optimization of circuit breaker,signal setting and on-site infrastructure acceptance.
