摘要
继电器是自动控制系统中常用的电器,它用于接通和断开电路,用以发布控制命令和反映设备状态,以构成自动控制和远程控制电路。铁路信号继电器是将电信号从一个导体传向另—个导体,在导体与导体的连接处就会产生电接触。这种传导是借助于继电器接点完成的,接点直接承担着接通和分断这种传导,它的性能是影响传导工作可靠性、稳定性和精确性的关键因素。
A relay is a commonly used electrical appliance in an automatic control system. It is used to turn on and off a circuit to issue control commands and reflect the status of equipment to form an automatic control and remote control circuit. A railway signal relay relays electrical signals from one conductor to another, and electrical contact occurs between the conductor and the conductor. This conduction is accomplished by means of a relay contact, which is directly responsible for making and breaking such conduction. Its performance is a key factor that affects the reliability, stability and accuracy of the conduction operation.
