Abstract

The invention relates to the technical field of vibration monitoring, and discloses an online monitoring system for power transmission line vibration. The system comprises a vibration monitoring instrument, a controller, a wireless communication module, a data communication module, an SCADA system, a client and a data processing server. The vibration monitoring instrument is mounted on a cross armof a power tower; the controller is mounted on the power tower and is in communication connection with the vibration monitoring instrument; the controller is in communication connection with the wireless communication module; the wireless communication module is connected with a Web server through Internet; the wireless communication module is connected with the data communication module; the data communication module is connected with the SCADA system through the data processing server; and the data processing server is respectively connected with the Web server and the client. A real-time early warning service can be provided for large-span safe operation of the power transmission line by rapidly and accurately acquiring, transmitting, processing and managing a large amount of data andinformation of large-span vibration of the line and mastering the change of the vibration elimination effect of the vibration prevention device of the ground wire in time.

Description

technical field [0001] The invention relates to the technical field of vibration monitoring, in particular to an online vibration monitoring system for transmission lines. Background technique [0002] Overhead line breeze vibration is a kind of overhead line vibration phenomenon caused by a gas vortex (Karman vortex) alternately shedding on the leeward side of the overhead line. At present, almost all high-voltage power transmission lines are affected by breeze vibration, especially on large spans , due to the characteristics of large span, high suspension point and open waters, the vibration energy transmitted by the wind to the ground wire is greatly increased, and the vibration intensity of the ground wire is much more serious than that of ordinary spans. Safe operation brings serious harm, and usually the direct loss of the line change project itself can be as high as several million yuan. [0003] Now in any area of ​​the world, almost all high-voltage overhead power ...
