Line Online Monitoring Device - Function: Sharing the Principle of Galloping Monitoring System

Online Line Monitoring Device - Function: Galloping Monitoring System

I. Overview

In nature, wind is a common weather phenomenon, and different wind forces have various impacts on us, such as wind power generation. However, for power transmission departments, excessive wind can sometimes affect the normal operation of transmission lines. When lines swing with strong winds, excessive swing amplitude can easily cause line tripping and increase the wear degree of line connection fittings. Power grid operation and maintenance personnel have no good solutions to this. The emergence of Telikang's Online Line Monitoring Device - Function: Galloping Monitoring System provides power grid operation and maintenance personnel with data support when facing transmission line galloping disasters, facilitating later intelligent line management.

III. Working Principle of Online Line Monitoring Device - Function: Galloping Monitoring System

The built-in detection unit of Online Line Monitoring Device - Function: Galloping Monitoring System can collect real-time galloping data of lines and send the data to the back-end management platform in real time through the wireless communication module. Operation and maintenance personnel can monitor the galloping conditions of multiple lines remotely at the same time and respond to line abnormalities in a timely manner. It adopts wind-solar complementation for front-end power supply, and the whole equipment is easy to install. With the power supply mode of wind-solar complementation plus battery, it can be directly installed on the wire and started, without frequent charging in the later stage.

IV. Application Cases

Two sections of lines under the jurisdiction of a power department of a city bureau in Shandong Province often have the problem of excessive line galloping amplitude. The reason is that the wires in this area are prone to uneven icing, and the area around the wires is open without shelter, with frequent wind. This leads to rapid wear of line clamps and fittings, and even power outage accidents. After the installation of Online Line Monitoring Device - Function: Galloping Monitoring System, operation and maintenance personnel can check the on-site wire galloping data anytime and anywhere, avoiding serious consequences caused by failure to respond in time when the wire galloping amplitude is too large.

V. Postscript

The problem of transmission line galloping has always been difficult to monitor, so power grid departments have no good means to deal with it. In addition, with the frequent occurrence of extreme weather in recent years, the originally regular wind season has become unpredictable. Operation and maintenance personnel cannot obtain real-time on-site galloping data, so they cannot respond to the disasters caused by galloping in a timely manner. Telikang's Online Line Monitoring Device - Function: Galloping Monitoring System can monitor several characteristic quantities of lines during galloping disasters in real time and send them wirelessly to the background. The background software compares the set early warning values to decide whether to alert operation and maintenance personnel, allowing them to take the initiative when facing galloping problems.
