| 摘 要： | 分析了计算机联锁系统继电器电路中电阻-电容电路的特点,阐述了几种典型继电器电路中电阻-电容电路的作用。通过增加电阻-电容电路,可使继电器延时落下。通过选取合适大小的电容和电阻值,可以满足继电器电路对时序的要求。电阻-电容电路在增加继电器缓放时间的同时,对电路稳定性也存在一定的影响,需从继电器常态等其他因素综合考虑电路的整体结构。

| Abstract: | The characteristics of RC circuit in relay circuit of computer interlocking system is analyzed.Function of RC circuit in several typical relay circuits is expounded.By adding RC circuit,the fall of relay circuit can be delayed.By choosing appropriate value of voltage and resistance,requirement of relay sequential circuit can be satisfied.While increasing the delay time of the relay,RC circuit also exerts certain impact on the circuit stability.The overall structure of circuit must be considered with other factors such as relay standard status. |
