Embodiment Construction

[0049] as attached figure 1 As shown, an online high-voltage cable line fault location device based on traveling wave principle and multi-source data fusion of the present invention includes a data collection device, a data background, a server and a front end of equipment.

[0050] The data collection device is used to collect parameter data of faulty cables on site and transmit the data to the data background.

[0051] The data background is used to collect parameter data of faulty cables. After summarizing the data, package it to the server.

[0052] The server uses a computer with large capacity and high computing power to analyze and process data, and packs and sends the analysis results to the front end of the device.

[0053] The device front end refers to portable devices such as tablet computers and mobile terminals, which are used to send fault diagnosis information to operation and maintenance personnel.

[0054] A data collection device is installed at both ends...

Abstract

The invention relates to a multi-source data fusion high-voltage cable line fault on-line positioning device and method based on a traveling wave principle. The positioning device comprises a data collection device, a data background, a server and an equipment front end. According to the improved cable fault accurate identification and positioning method, signals are deeply researched and analyzed, characteristic semaphore is further extracted by using various signal analysis methods, and through theoretical analysis and simulation, fault judgment can be further improved, and a current cable detection method is improved. Operation and maintenance personnel are assisted to discover cable fault hidden troubles in time, normal operation of the cable is ensured, electric power accidents are reduced, and an effective solution is provided for intelligent detection of a power grid cable line.

Description

technical field [0001] The invention belongs to the field of safe operation of power transmission and distribution cables, and in particular relates to an online fault location device and location method for high-voltage cable lines based on traveling wave principle and multi-source data fusion. Background technique [0002] It is generally believed that the service life of power cables under normal conditions is 20 to 30 years, but because cables are often placed in underground trenches or directly buried in the soil, its construction environment and use conditions have greatly affected its lifespan. changes. Long-term contact with soil, water, and moisture, the insulation layer of the cable is easy to be corroded and penetrated, and the wear and tear during cable manufacturing or installation can cause hidden dangers and cause failures in the future. Once the underground cable fails. It is very difficult to judge its fault point, which will not only cause the loss of man...
