接触导线拉出值超限检测系统

A System for Detecting the Excessive Staggers of Contact Wires

介绍了安装在电气化铁路运营电力机车上的接触导线拉出值超限检测装置。在该系统中利用了光电检测技术，并采用反射式红外光电开关作为拉出值超限检测传感器。空气隔离的光信号传递方式有效解决了高低电压隔离和信号传输问题。经实际运行证明，该检测装置抗干扰能力强，工作稳定可靠，检测结果准确。

A device for detecting the excessive staggers of contact wires is described, which is installed on an electric locomotive. The opto electric technique is applied in the system with the optoelectronic switch used as the excessive staggers detecting transducer. The voltage isolation and optical transmission of signals through the air from the high voltage side to the low one are realized. The practical operations show that the detecting device has the properties of accuracy, high reliability and anti interference.
