New power cable partial discharge monitoring system

The present invention relates to a novel partial discharge between the power cable line monitoring system, said monitoring node, the central node and the wireless transmission data management platform, without laying a communication cable, with high reliability, real-time, and low cost. The UHF sensor, is formed in the form of welded seamless outer surface of the insulating layer of the endless belt, facilitate the spread of the UHF signal, improving the accuracy of monitoring partial discharge and avoids damage XLPE power cable accessories original insulation and electric field distribution. Since the sensor is a sheet UHF sensor, may be cut according to the thickness and site installation of XLPE power cable accessories, a wide range. Furthermore, the feed line having one end connected to the UHF sensor, the other end of the feed line head waterproof N, N waterproof head is used to connect the partial discharge detection device, in actual operation, the water head N easy installation and removal can be a partial discharge detection device.
