Online monitoring terminal of ice coating early warning system for transmission lines
I. Overview
Every year in early spring or around the time of winter, we see news reports of ice coating disasters on transmission lines in various regions. In mild cases, the load on line hardware is too large and the sag point is too low, leading to electric faults; in severe cases, line hardware and conductors may break. Due to the high humidity in some southern regions of China, when hit by a continuous cold snap, heavy ice sections are prone to occur. The operation and maintenance departments often need to frequently send staff to the site to inspect and record the ice coating conditions on the lines, and carry out de-icing treatment for lines with severe ice coating, which is inefficient. Power grid departments have been pursuing a solution that can prevent ice coating problems early and respond timely to dangerous ice coating values. The Online monitoring terminal of ice coating early warning system for transmission lines of Telcom is developed based on the above background.
II. Working principle
The Online monitoring terminal of ice coating early warning system for transmission lines is powered by a combination of solar panels and high-capacity batteries as a whole. In normal times, the solar panels provide daily power for the equipment, and the excess power is stored in the batteries. When there is insufficient sunlight or at night, the batteries are used for power supply. The tension sensor at the front end of the equipment can measure the load data of the conductor, and calculate the ice coating thickness through background operation. If the calculated ice coating value exceeds the early warning threshold, an alarm message will be immediately sent to the operation and maintenance staff, so that de-icing measures such as melting ice can 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. Equipped with functions such as battery voltage collection;
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 of ice coating early warning system for transmission lines has changed the current situation where operation and maintenance staff need to inspect ice coating conditions on site. 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 staff formulate more reasonable de-icing schemes and have less impact on the service life of the lines themselves.
V. Installation suggestions
The Online monitoring terminal of ice coating early warning system for transmission lines adopts the weighing method to calculate the ice coating thickness. This method has small calculation error, but the obtained ice thickness is the average ice coating thickness. In order to meet the monitoring needs of different ice thicknesses in lines in heavy ice areas, it is recommended to match with a microwave ice coating device for auxiliary monitoring.
VI. Alternative names of the product
Online line monitoring device, ice coating monitoring system, transmission line ice observation system, Online monitoring terminal of ice coating early warning system for transmission lines, important transmission channel ice coating monitoring device, intelligent online ice observation device
