Early warning method and device for hidden trouble of power transmission line

Abstract

The invention discloses an early warning method and device for hidden trouble of a power transmission line. The method comprises the following steps: acquiring environmental data about the surrounding environment of the power transmission line in real time; performing comprehensive hidden danger detection on the power transmission line based on the environmental data, wherein the comprehensive hidden danger detection comprises tower touch detection, forest fire detection, tree obstacle detection and lightning stroke detection; and when the detection result of the tower touch detection, the forest fire detection, the tree obstacle detection or the lightning stroke detection is abnormal, triggering and generating a tripping early warning based on the abnormal detection result, so that a user can carry out corresponding maintenance operation. The environment data of the environment where the power transmission line is located can be collected in real time, different types of early warning detection can be carried out based on the environment data, when abnormity is detected, a user can be notified in an early warning mode so that the user can carry out corresponding maintenance operation according to the alarm, the maintenance time consumption of the user can be shortened, and the maintenance efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of transmission line fault alarm, in particular to a method and a device for early warning of hidden dangers of transmission line faults. Background technique [0002] Transmission lines are the arteries that transmit electricity, with wide distribution and long transmission distances. As an important part of the smart grid, the health of the transmission line is related to the reliable and stable operation of the power grid. Transmission line fault tripping is one of the frequent accidents in the power grid, and the tripping fault has a great impact on system safety, equipment safety and power supply reliability. Each tripping fault may damage the equipment, and even cause a large-scale power outage in the system, which not only brings huge losses to the power grid, but also has a greater impact on normal industrial and agricultural production and residents' lives. [0003] In order to ensure the stable t...

Problems solved by technology

[0004] However, the commonly used detection methods at present have the following technical problems: First, the commonly used detection methods can only determine whether the transmission line is faulty, and different transmission lines are distributed in different places, which may be set in deep forests, roadsides, and halfway up the mountain. Transmission lines in different places (especially in places with harsh environments such as barren mountains and mountains) may cause different types of failures due to changes in their environment, making technicians need to determine the specific cause and location of the failure again, which increases the time spent on troubleshooting and maintenance.
