两种类型中央事故信号装置的比较

The Comparison of two Kinds of the Central Trouble Signal Apparatus

在目前供电系统常规采用继电式控制的情况下,对继电式和PLC式两种控制装置方式进行了比较。研究发现,PLC装置具有体积小,组装方便,编程简单,可靠性高,抗干扰能力强等优点,其性能明显优于前者。

It introduced relay style and PLC of two control modes in the power supply system of central trouble signal apparatus,and also compared with them under using the relay style control in the power supply systerm at present.The results showed that the PLC has many advantages,such as small volume,convenience assemble,simple program,high reliability and strong anti-interference ability,so its performance is superior to the former.
