▎ 摘　　要

NOVELTY - The device has a graphene wire (2) wound on an annular superconductor inner core. The graphene wire is electrically connected with an input end of a signal processing module (3). An output end of the signal processing module is electrically connected with an input end of a signal wireless transmission module (4). An output end of the signal wireless transmission module is connected with an input end of a signal rendezvous point (5). An insulating layer (6) is wrapped with a superconductor inner core (1) that is wound with the graphene wire. The signal processing module is provided with a power supply unit, a filter circuit, a signal amplifying circuit and an output circuit. USE - Electric transmission line corona discharge detecting device. ADVANTAGE - The device can measure corona discharge signal, avoids electrical connection between a high-voltage cable and a measuring loop so as to inhibit noise signal interference, and ensures detection accuracy and efficiency of corona discharge signal. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram of an electric transmission line corona discharge detecting device.
