Online Monitoring Terminal for Transmission Line Ice Coating Early Warning System
I. Overview
Every early spring or around the time of winter, we see ice coating disasters on transmission lines in various regions in the news. In mild cases, the load on line fittings becomes too large, and the sag point is too low to cause discharge to the ground; in severe cases, line fittings and conductors may break. In some areas of southern China, due to high humidity, when continuous cold snaps hit, heavy ice sections are prone to occur. The operation and maintenance department often needs to frequently send staff to the site to check and record the ice coating conditions of lines, and carry out ice melting treatment for severely ice-coated lines, with poor efficiency. The power grid department has been pursuing a solution for early prevention of ice coating problems and timely response to dangerous ice coating values. The Online Monitoring Terminal for Transmission Line Ice Coating Early Warning System of Telincon was developed based on the above background.
II. Working Principle
The Online Monitoring Terminal for Transmission Line Ice Coating Early Warning System is powered by a combination of solar panels and high-capacity batteries as a whole. Normally, the solar panels provide daily power for the equipment, and the excess power is stored in the batteries. When sunlight conditions are poor or at night, the batteries are used for power supply. The tension sensor at the front end of the equipment can measure the conductor load data, and calculate the ice coating thickness through background calculation. If the calculated ice coating value exceeds the early warning value, an alarm message will be sent to the operation and maintenance personnel immediately, and ice removal measures such as ice melting will be taken in time to reduce the economic losses caused by ice coating.
III. Technical Parameters
1. Power supply system: Solar energy + battery
2. Working voltage: DC12V
3. Standby time: More than 30 days
4. Has the function of collecting battery voltage, etc.;
5. Has a good synchronization mechanism to ensure the synchronization of the collection time of each parameter;
IV. Postscript
The emergence of the Online Monitoring Terminal for Transmission Line Ice Coating Early Warning System has changed the current situation where operation and maintenance personnel conduct on-site surveys of ice coating conditions. The equipment sends the ice coating data monitored throughout the day to the background in real time through a wireless communication module, realizing that a back-end monitoring platform can access multiple sets of ice coating monitoring data, and the work efficiency is multiplied. In addition, the added video monitoring unit and micro-meteorological collection unit make the on-site ice coating conditions more intuitive, which can help operation and maintenance personnel formulate more reasonable ice removal plans, with little impact on the service life of the lines themselves.
V. Installation Suggestions
The Online Monitoring Terminal for Transmission Line Ice Coating Early Warning System uses the weighing method to calculate the ice coating thickness. This method has a small calculation error, but the obtained ice layer thickness is the average ice coating thickness. In order to meet the monitoring needs of different ice layer thicknesses in heavy ice area lines, it is recommended to match with a microwave ice coating device for auxiliary monitoring.
