摘要（英）：

The invention discloses a flow cable partial discharge online monitoring system, comprising a high frequency sensor, an extra-high frequency sensor, a preposition conditioning unit, a detection front end and a portable detection terminal, wherein the preposition conditioning unit comprises a preposition high frequency conditioning unit and a preposition extra-high frequency conditioning unit; the preposition high frequency conditioning unit is correspondingly connected with the high frequency sensor; the preposition extra-high frequency conditioning unit is correspondingly connected with the extra-high frequency sensor; the detection front end is connected with the preposition conditioning unit, and is used for collecting a signal transmitted by the preposition conditioning unit and sending relevant data after characteristic parameters of the signal are extracted; the portable detection terminal is wirelessly connected with the detection front end, and is used for receiving data sent by the detection front end and performing analysis and diagnosis on the data. The flow cable partial discharge online monitoring system is flexible and convenient to use, large in the coverage area, and capable of continuously working for a long time, greatly improving the antijamming capability of the field, and improving the reliability of a field detection result.
