Online Monitoring Device for Transmission Line Icing
I. Overview
Every year in early spring or around the time of winter, icing disasters on transmission lines occur in various regions. In mild cases, the load on line hardware becomes excessive, and the sag point is too low, leading to discharge to the ground; in severe cases, line hardware and conductors may break. Due to the high humidity in some southern regions of China, when continuous cold snaps hit, heavy icing sections are prone to form. Operation and maintenance departments often need to frequently send staff to the site to inspect and record the icing conditions of lines, and carry out de-icing treatment for iced lines, which is inefficient. Power grid departments have been pursuing a solution that can prevent icing problems early and respond timely to dangerous icing values. The Online Monitoring Device for Transmission Line Icing from Telcom is developed based on the above background.
II. Working Principle
The Online Monitoring Device for Transmission Line Icing is powered by a combination of a solar panel and a high-capacity battery. In normal times, the solar panel provides daily power for the device, and the excess power is stored in the battery. When sunlight is insufficient or at night, the battery is used for power supply. The tension sensor at the front end of the device can measure the conductor load data, and calculate the icing thickness through background operation. If the calculated icing value exceeds the early warning threshold, an alarm will be immediately sent to the operation and maintenance personnel, who can take de-icing measures such as melting ice in time to reduce the losses caused by icing.
III. Technical Parameters
1. Power supply system: Solar energy + battery
2. Working voltage: DC12V
3. Standby time: More than 30 days
4. Equipped with functions such as battery voltage acquisition;
5. Equipped with a synchronization mechanism
IV. Postscript
The emergence of the Online Monitoring Device for Transmission Line Icing has changed the current situation where operation and maintenance personnel need to conduct on-site inspections of icing conditions. The device uses a wireless communication module to send real-time icing data monitored throughout the day to the background, enabling a backend monitoring platform to access multiple sets of icing monitoring data, thus improving work efficiency. Additionally, the integrated video monitoring unit and micro-meteorological acquisition unit make the on-site icing conditions more intuitive, helping operation and maintenance personnel formulate more reasonable de-icing plans, and having less impact on the service life of the lines themselves.
V. Installation Suggestions
The Online Monitoring Device for Transmission Line Icing uses the weighing method to calculate the icing thickness. This method has small calculation errors, but the obtained ice thickness is the average icing thickness. To meet the monitoring needs of different ice thicknesses in heavy icing areas, it is recommended to pair it with a microwave icing monitoring device for auxiliary monitoring.
