Abstract

The invention discloses a power transmission line fault monitoring device and method, and can carry out comprehensive monitoring on a fault state of a power transmission line. The device comprises a mountain fire monitoring unit, an ice coating monitoring unit, a dirty monitoring unit, a conductor galloping monitoring unit and a monitoring main station, wherein the mountain fire monitoring unit isused for monitoring whether an abnormal heat source exists in a power transmission line passage and tower region, if yes, timely carrying out fire extinguishing, and uploading monitored data to the monitoring main station; the ice coating monitoring unit is used for monitoring conductor tension and meteorological environment data near the line and uploading the monitored data and data monitored by the conductor galloping monitoring unit to the monitoring main station; the dirty monitoring unit is used for detecting equivalent salt deposit density data of an insulator of the power transmissionline and uploading the monitored data to the monitoring main station; the conductor galloping monitoring unit is used for monitoring galloping information of the line and transmitting the galloping information to the ice coating monitoring unit; and the monitoring main station is used for receiving the data monitored by the mountain fire monitoring unit, the ice coating monitoring unit, the dirtymonitoring unit and the conductor galloping monitoring unit and carrying out analysis on a condition of the power transmission line

Description

technical field [0001] The present disclosure relates to the field of transmission line status monitoring, in particular to a transmission line fault monitoring device and method. Background technique [0002] The transmission line crosses mountains, rivers, etc., and is far away from the office of the operation and maintenance personnel. The time from the office to the transmission line is closely related to the area under the jurisdiction of the operation and maintenance department, topography, road conditions, etc. The status monitoring data of the transmission and transformation line It is a large part of the data in the smart grid, including not only the online status monitoring data, but also the basic information of the equipment, experimental data, defect records, etc., and the requirements for the reliability and real-time performance of data processing are very high. How to quickly locate the fault after the fault of the transmission line is an important technical ...
