Abstract

The invention discloses a high-voltage cable state intelligent diagnosis and accurate positioning device in the technical field of circuit fault positioning equipment, and the device comprises a first integrated box shell, a second integrated box shell, a power module, a power switch, a lightning arrester, a power output port, a wireless router, and a 4G/5G antenna output port. A plurality of high-frequency current signal input ports and cable fault traveling wave current signal input ports are fixed on one side of the second integrated box shell, and a plurality of power frequency current input ports and a GPS clock timing antenna are arranged on the other side of the second integrated box shell. The cable fault traveling wave current, the body power frequency current or grounding current and the high-frequency pulse current signals are sent back to a background server end in a 4G/5G and GPS wireless mode, related personnel can be timely notified of various monitoring state information and fault positioning results in a short message or WEB mode, processing measures are timely provided to prevent faults or eliminate the faults, the device has the advantages of small data volume, high processing speed, simple hardware, low cost, strong interference resistance and the like.

Description

technical field [0001] The invention relates to the technical field of circuit fault location equipment, in particular to an intelligent diagnosis and precise location device for a high-voltage cable state. Background technique [0002] Power cables are widely used in power grids, but most cables operate in poor working conditions, and are always facing the threat of soil and groundwater corrosion and various excavation operations. Once damaged, it will directly cause short-circuit tripping of the line, seriously affecting the reliability of power supply. [0003] After retrieval, Chinese Patent No. CN210487896U discloses a high-voltage power cable fault on-line positioning device. The setting of the high-voltage cable short-circuit fault precise positioning device is to install a GPS timing module in the device, and use the precise clock provided by GPS to measure the arrival of traveling wave signals. The time difference between the two ends of the high-voltage cable deter...
