摘要:

电磁传感器是根据电磁感应原理用于检测电磁信号的。在精确检测电缆故障点时,根据故障点产生的磁场变化,电磁传感器拾取到这种变化的磁场信号,并将其转换成感应电压,感应电压经放大、整流处理后,用于后续检测指示电路,最后确定故障点的位置。

Abstract:

An electromagnetic sensor is designed according to the principle of electromagnetic induction for electromagnetic signals detection.The electromagnetic sensor can pickup the change of the magnetic field signal according to the changing magnetic field generated by the fault point,and converts it into the induced voltage.The induced voltage is amplified and rectified and then fed into the follow-up testing and indicating circuit to determine the location of the fault point.

Key words: Inductor;electromagnetic;cable fault location
