Ice Monitoring Device for Overhead Transmission Lines
I. Overview
Every year in early spring or around the time of winter, news reports about ice disasters on transmission lines across various regions emerge. These disasters, at their mildest, cause excessive load on line hardware and low sag points leading to electric discharge to the ground; at their most severe, they result in fracture of line hardware and conductors. Due to the high humidity in some southern regions of China, when hit by continuous cold snaps, heavy ice sections are prone to form. Operation and maintenance departments often need to frequently dispatch staff to on-site locations to inspect and record the ice conditions of transmission lines, and carry out de-icing treatments for 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 values. The Ice Monitoring Device for Overhead Transmission Lines from Telcom is developed based on the above context.
II. Working Principle
The Ice Monitoring Device for Overhead Transmission Lines is entirely powered by a combination of solar panels and high-capacity batteries. During normal operation, solar panels supply daily power to the device, with excess electricity stored in the batteries. When sunlight is insufficient or at night, the device switches to battery power. The tension sensor at the front end of the device measures conductor load data, which is then processed by the backend to calculate ice thickness. If the calculated ice value exceeds the warning threshold, an alarm is immediately sent to operation and maintenance personnel, allowing timely implementation of 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 Ice Monitoring Device for Overhead Transmission Lines has changed the current situation where operation and maintenance personnel had to conduct on-site inspections of ice conditions. The device uses a wireless communication module to transmit real-time ice monitoring data to the backend throughout the day, enabling a single backend monitoring platform to access multiple sets of ice monitoring data, thus multiplying work efficiency. Additionally, the integrated video monitoring unit and micro-meteorological acquisition unit make on-site ice conditions more intuitive, assisting operation and maintenance personnel in formulating more reasonable de-icing plans and having minimal impact on the service life of the lines themselves.
V. Installation Recommendations
The Ice Monitoring Device for Overhead Transmission Lines adopts the weighing method to calculate ice thickness. This method has small calculation errors, but the obtained ice thickness is the average ice thickness. To meet the monitoring needs of different ice thicknesses in heavy ice zone lines, it is recommended to pair it with a microwave ice monitoring device for auxiliary monitoring.
