Real-Time Monitoring Technology Service for Transmission Line Icing
I. Overview
Every year in early spring or around the time of winter onset, news reports frequently cover transmission line icing disasters across various regions. At the minimum, such disasters can cause excessive load on line hardware and low sag points leading to flashovers to the ground; at the worst, they can result in fracture of line hardware and conductors. Due to the high humidity in some southern regions of China, when hit by persistent cold snaps, heavy icing sections are prone to occur. Operation and maintenance (O&M) departments often need to frequently dispatch staff to on-site locations to inspect and record line icing conditions, and perform de-icing treatments on severely iced lines, which is inefficient. Power grid departments have been seeking a solution that enables early prevention of icing issues and timely response to dangerous icing levels. The Real-Time Monitoring Technology Service for Transmission Line Icing from Telincom was developed based on the above context.
II. Working Principle
The Real-Time Monitoring Technology Service for Transmission Line Icing is entirely powered by a combination of solar panels and high-capacity batteries. During normal times, solar panels supply daily power for the equipment, with excess electricity stored in the batteries. When sunlight is insufficient or at night, the battery power is activated. The tension sensor at the front end of the equipment can measure conductor load data, and calculate the icing thickness through background computing. If the calculated icing value exceeds the warning threshold, an alarm will be immediately sent to O&M staff, prompting timely de-icing measures such as melting ice to reduce economic losses caused by icing.
III. Technical Parameters
1. Power Supply System: Solar Energy + Battery
2. Operating Voltage: DC12V
3. Standby Duration: More than 30 days
4. Equipped with functions such as battery voltage acquisition;
5. Features a good synchronization mechanism to ensure the synchronization of parameter acquisition timings;
IV. Postscript
The advent of the Real-Time Monitoring Technology Service for Transmission Line Icing has changed the status quo of O&M staff conducting on-site icing inspections. The equipment uses a wireless communication module to transmit real-time icing data monitored throughout the day to the background, enabling a back-end monitoring platform to access multiple sets of icing monitoring data, thus multiplying work efficiency. Additionally, the integrated video monitoring unit and micro-meteorological acquisition unit make on-site icing conditions more intuitive, helping O&M staff formulate more reasonable de-icing plans with minimal impact on the service life of the lines.
V. Installation Recommendations
The Real-Time Monitoring Technology Service for Transmission Line Icing adopts the weighing method to calculate icing thickness. This method has a small calculation error, 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 device for auxiliary monitoring.
