摘要
在快脉冲信号测量和传输线故障诊断中,常用到精确的传输线延迟时间。论文介绍一种用示波器精确测量传输线延迟时间的方法,并介绍了用示波器诊断传输线故障点的方法,在实际工作中得到成功应用。在遭遇"中国南方雪灾"等类似问题时,传输线故障诊断方法将对快速查找和修复电力线路、通讯电缆等有很大的帮助。
In the signal measurements and the diagnoses of transmission line＇s hitch fields, the transmission line＇s delay time is usually used. In the paper, a method of using oscilloscope to measure transmission line ＂s delay time is discussed. A method diagnosing transmission line＇s hitches is also provided. The methods have been used successfully. It will help the power transmission line＇s and communication line＇s hitches to be found and restored fast in many fields, for example, the heavy snow disaster in the southern of China.
