摘要
为提高供电的可靠性,用可编程序控制器(简称PLC)代替继电器实现电气主接线——双母线切换母线时隔离开关和断路器的操作过程.设计模拟电路和PLC控制程序,以实现母线切换,误操作判断,并用灯光来反应断路器的状态,用音响作为故障报警信号.
In order to improve to replace relays, for realizing the main adjoin wire ——double - bus when it changes bus, the operation course of the disconnectors and circuit - breakers. Simulation circuit and PLC program are designed to realize bus＇s change, misoperation judgment and light is used to reflect the status of the circuit - breakers, with sound the signal of breakdown.
