仪表自动化中继电器型开关量的探讨

The discussion of relay switching volume in instrument automation

变电站仪表自动化是国家电网随着科技不断发展的成果。当下变电站自动化系统中一般选用的是继电器开关量,来作为开关型控制电器的主要结构,达到对高低压回路进行接通以及断开的作用,从而实现控制以及报警的目的。文章通过对变电站自动化系统中,固态继电器开关量供电回路进行分析,对目前站控程序不统一的问题进行了归纳分析,最终给出了更为合理的接线方式,改善了目前程序不统一的问题,为我市的仪表自动化优化给出了建设性意见。

The automation of substation instrumentation is the result of the continuous development of national power grid? The substation automation system is generally selected in relay switch, and as the main structure of switch type control appliances, to achieve the high and low voltage circuit on and off, so as to realize the purpose of control and alarm? Based on substation automation system, the amount of solid state relay switch power supply circuit is analyzed, the current stand accused of program is not unified question has carried on the induction analysis, finally presents a more reasonable wiring way, the question of improving the current program is not unified, constructive Suggestions are given for zhuhai instrument automation optimization?
