摘要
随着电厂自动化程度的提高,电气自动控制柜内电器元件越来越多。若设计考虑不周,将导致电气设备运行过程中控制回路电压异常,影响继电器的动作与返回,设备无法正常工作。本文以电气控制柜拒动为例,讨论实际运行电压与理论运行电压相差较大时对控制回路的影响,提出了简单易行的解决方法。
With the improvement of automation of power plants,electrical components in the electrical control cabinet are growing.If the design lacks,there may be abnormal voltage control circuit during operation,which may affect the relay operation and return,the device may do not work.The article takes electrical control cabinet rejection for example,discusses the effect on control loop when actual operating voltage and theoretical voltage differs,and easy solution is proposed.
