| Abstract: | 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. |
