Abstract

The invention relates to a power transmission line vibration state monitoring device, in particular to a power transmission line vibration monitoring device. The problem that no mature equipment or devices exist for monitoring power transmission line vibration conditions at present is solved. The power transmission line vibration monitoring device is composed of a main control computer, a vibration measurement auxiliary machine, an inclination angle measurement auxiliary machine, a wind speed measurement auxiliary machine and a PC in a monitoring center, wherein the vibration measurement auxiliary machine transmits power transmission line vibration frequency signals to the main control computer, the inclination angle measurement auxiliary machine transmits signals of inclination angles at the two ends of a power transmission line to the main control computer, the wind speed measurement auxiliary machine transmits local wind speed signals to the main control computer, and the PC receives the corresponding signals sent by the main control computer and processes the received corresponding signals under the support of the corresponding software. According to the power transmission line vibration monitoring device, line vibration frequency and amplitude detection can be achieved, information collection, information transmission and information processing and analysis are integrated, and the power transmission line vibration conditions are comprehensively monitored.

Description

technical field [0001] The invention relates to a vibration state monitoring device for a power transmission line, in particular to a vibration monitoring device for a power transmission line. Background technique [0002] Today, with my country's rapid economic growth and increasingly tense energy sources, the safety of transmission lines has been paid more and more attention. Transmission lines are an important part of the power grid system. In the wild environment, they are easily affected by natural disasters such as strong winds and rainstorms, causing various accidents. In recent years, various accidents on transmission lines have occurred frequently, and the line fatigue caused by wind vibration has caused line breakage, seriously affecting the normal operation of the power grid, and causing huge economic losses. Monitoring the vibration status of transmission lines (including vibration frequency and vibration amplitude) is of great significance to ensure the safe an...
