System and method for on-line monitoring of suspended overhead transmission lines

Abstract

Suspended overhead transmission line online monitoring system and method, the system includes a suspended monitoring device, a master station system; the suspended monitoring device includes a main board module, a sensor module, a data storage unit, a suspension module, a power-taking device, a communication module, Camera module, inner diameter adjustment mechanism. The main board module is respectively connected with the sensor module, the suspension module, the camera module, the communication module and the data storage unit; the suspension module is connected with the inner diameter adjustment mechanism as a whole. The suspension monitoring device is used to collect various meteorological conditions and displacement of the transmission wire, and transmit the data to the main station system through the communication module. Through the model established by the neural network in the main station system, it can be judged whether the corresponding warning threshold has been reached. On-line monitoring of galloping or icing of transmission wires under various weather conditions. The on-line monitoring system and method of the suspended overhead transmission line of the present invention can realize the self-adaptive adjustment of the monitoring device when detecting transmission lines with different outer diameters by adjusting the inner diameter conversion mechanism, which overcomes the non-adjustable problem of traditional wire fixed monitoring equipment Shortcomings increase the versatility of the device of the present invention.

Description

technical field [0001] The invention belongs to the field of overhead power transmission line engineering, and in particular relates to an on-line monitoring system and method for suspended overhead power transmission lines. Background technique [0002] With the development of my country's smart grid, a number of new large-capacity, long-distance overhead transmission lines will be built soon, and their line security is facing new challenges. Large-span overhead transmission lines usually cross rivers, seas and lakes. In areas with bad weather, when subjected to complex environments such as wind, rain, ice and snow, the transmission line will have safety problems such as breeze vibration, dancing, and even ice-covered disconnection, resulting in line breakage and hardware damage. , or even the collapse of line towers, etc., will cause large-scale power outages, seriously affecting people's production, life and property safety. Therefore, through the online monitoring devic...

AI Technical Summary

Problems solved by technology

However, fixedly installed monitoring devices are often loosened due to wind vibration, galloping and thermal expansion and contraction of the transmission line, which affects the normal use of the sensor, reduces the service life of the monitoring device, and increases the maintenance cost of the monitoring system.

At the same time, after the monitoring device is loose and deviates from the original fixed position, the monitoring device will slip along with the vibration of the transmission line and touch other anti-vibration fittings on the transmission line, affecting the safety of the transmission line

[0005] Therefore, in order to solve the shortcomings of the existing fixed monitoring devices such as easy loosening, poor stability, and low durability, it is urgent to develop a long-term on-line monitoring device and method for intelligent transmission lines with novel design, durability, and high performance.
