Icing on power transmission lines continuously increases the load on the conductors, causing the ice layer to thicken and steadily reducing the line’s safety margin. Once the load exceeds the line’s design limits, it can easily trigger various ice-related accidents. For example, when the load is transferred to the towers and the tensile force exceeds the tower’s load-bearing capacity, the towers may tilt or crack; in severe cases, they may collapse. To address the need for ice condition monitoring on transmission lines, Dinsee Smart Technology has launched the DX-WSP100-GB Transmission Line Ice Thickness Detection Device. This is a hybrid online monitoring system that integrates image and tension sensor technologies to collect real-time data on conductor tension, on-site images, and micro-meteorological conditions, calculate the thickness of ice on the conductors, and predict the trends of ice-related incidents.
As an effective solution for monitoring ice conditions on power grids, the device’s front end integrates an image capture unit, a high-precision tension sensor, and a power supply module, enabling it to capture images of the conductors and right-of-way at monitoring points.
Core Capabilities of the Equipment
1. Efficient and Stable Live Installation: This device supports live installation; its innovative design, which eliminates the need to shut down power, significantly improves installation efficiency without disrupting normal power supply, thereby ensuring the continuity of power delivery.
2. Multi-modal Monitoring and Precise Early Warning: The front-end system consists of image and video capture devices, high-precision tension sensors, power supply modules, and other components. It captures photos of the conductors and transmission corridors at monitoring points and transmits the data via 4G, 5G, Wi-Fi, and other communication methods, allowing users to view ice thickness data, on-site images and videos, and early warning information at any time. This helps power utilities monitor ice accumulation conditions and trends in real time. Combined with image and video capture as well as micro-meteorological data collection capabilities, the system can also calculate ice accumulation thickness, predict ice growth trends, and promptly identify potential safety hazards.
3. Diverse Communication Options for Seamless Data Transmission: The wireless communication unit supports multiple modes (4G/5G/Wi-Fi/LoRa), ensuring uninterrupted data transmission in both areas with and without signal coverage, and guaranteeing that monitoring data is transmitted to the server in a timely and accurate manner.
4. Comprehensive Features Ensure Reliable Operation: This device simulates power line data modeling to enable precise, real-time data calculations; the data collection interval can be freely configured remotely; it supports a mobile app, allowing users to view data at any time; it features data encryption and supports integration with the unified back-end systems of State Grid and China Southern Power Grid, providing comprehensive safeguards for the safe operation of transmission lines.
Practical Value
This integrated ice monitoring system replaces manual on-site inspections and provides 24-hour continuous monitoring of conductor loads and changes in ice buildup. By detecting ice buildup trends in advance, it shifts the focus from reactive emergency repairs to proactive early warning of ice-related disasters, thereby reducing the likelihood of ice-related incidents such as conductor breaks, tower collapses, and conductor fluttering, and minimizing power outage losses and on-site emergency repair costs caused by ice disasters.
