Power transmission line comprehensive sensing system

Abstract

The invention discloses a power transmission line comprehensive sensing system. The system comprises a distributed short-circuit fault acquisition and processing unit, a distributed ground fault and online temperature measurement acquisition and processing unit, a background comprehensive management software platform and a server, wherein the distributed short-circuit fault acquisition and processing unit, the distributed ground fault and online temperature measurement acquisition and processing unit and the background comprehensive management software platform are electrically and bidirectionally connected with the server. According to the online sensing system, comprehensive monitoring of the cable state is achieved by means of the intelligent wireless communication technology, symptoms of cable operation state abnormity or faults are mastered in time, and data are reported so that corresponding measures can be taken, fault points can be rapidly reached, cable faults can be rapidly positioned and maintained, the maintenance period can be optimized, therefore, major accidents are avoided or reduced.

Description

technical field [0001] The invention relates to the technical field of wire monitoring, in particular to a comprehensive sensing system for power transmission lines. Background technique [0002] The transmission network covers a vast area and requires a lot of maintenance work. Once a problem occurs on the overhead high-voltage transmission line, it will have a major impact on national production. The self-healing and self-adaptive requirements of the transmission network require the power sector to keep abreast of the operation status of the transmission line, and timely discover, Rapid diagnosis and elimination of potential faults, as well as timely detection and treatment of faults, to avoid large-scale, long-term power outages and other accidents, this situation requires the establishment of a transmission line monitoring system to lay a solid foundation for the reliable operation and timely maintenance of transmission lines A solid foundation, but most of the overhead hi...

[0002] The transmission network covers a vast area and requires a lot of maintenance work. Once a problem occurs on the overhead high-voltage transmission line, it will have a major impact on national production, and the self-healing and self-adaptive requirements of the transmission network require the power sector to keep abreast of the operation status of the transmission line, and timely discover, Rapid diagnosis and elimination of potential faults, as well as timely detection and treatment of faults, avoid large-scale, long-term power outages and other accidents. In this case, a transmission line monitoring system needs to be established to lay a solid foundation for the reliable operation and timely maintenance of transmission lines. A solid foundation, and most of the overhead high-voltage transmission lines in my country are erected in places far away from human habitation and high mountains, and the transmission lines cross rivers and rivers, which brings great trouble to the work of electric power workers

[0003] The existing comprehensive sensing system for transmission lines has a serious problem that it cannot monitor the operating status of the cable around the clock when it is in use, and cannot quickly and accurately locate the fault point of the cable, which will increase the probability of major accidents. And because the cable is in the trench, it will increase future maintenance costs
