The terrifying aspect of transmission line channel fires lies in their rapid spread, which not only threatens the safety of power supply, but may also trigger large-scale power outages, causing serious impacts on economic and social operations as well as people's lives. The sources of its generation are mainly the following:
1. Thunderstorms and lightning strikes trees or dry vegetation, generating high temperatures when strong currents pass through instantly, which may cause trees and other vegetation to burn, leading to fires in transmission line channels.
2. The high temperature and low humidity weather of time can dry up the vegetation inside the transmission line channel. In this case, even a small spark, such as an unextinguished cigarette butt discarded by pedestrians or sparks from high-temperature exhaust from vehicles, can trigger a fire. Especially in some areas with large vegetation coverage, dry grass and fallen leaves are everywhere flammable materials.
3. Forest fires or wasteland fires that occur in the surrounding areas, under the influence of wind, can spread rapidly and may spread to transmission line channels.
4. During festivals or sacrificial activities, people burn incense, paper, etc. near power transmission lines. Mars can easily be blown onto the surrounding vegetation by the wind, causing fires.
5. Agricultural use of fire involves burning straw in farmland near transmission lines to clean up the land. If the fire gets out of control, it will spread to the vegetation area of the transmission line channel.
The rapid production of high temperatures by a large fire can cause a decrease in the performance of the metal material of the wire, leading to situations such as breakage, disconnection, tripping, and power outages. Moreover, a large amount of smoke and ash from the fire adhere to the insulators, and the subsequent pollution flashover problem is also a headache.
Our company's transmission line fire hazard monitoring system DX-WPS100-SH, also known as online monitoring for preventing wildfires, can monitor the surrounding environment of transmission lines in real time and accurately. It uses advanced infrared thermal imaging, image recognition and other technologies to quickly detect small fire sources that may cause fires, such as sacrificial fires, agricultural fires, construction sparks, etc. The detection range reaches a radius of 3km or more, and potential fire hazards can be detected in the early stages.
Once a fire is detected, the device will immediately send an alarm reminder to the platform. Staff can also view real-time on-site video information or push image alarms through the background, WeChat, etc. The alarm methods include on-site alarms, background alarms, mobile alarms, etc., to ensure that users can timely detect and respond to the fire source, avoid damage to the transmission line caused by the spread of fire, and ensure the safe and stable operation of the transmission line.
In addition, the equipment can accurately capture the latitude and longitude positions of wildfires through the combination of Beidou satellite navigation system and 3D point cloud technology, providing guidance for rescue work. Through the path planning of GIS geographic information system, it helps operation and maintenance personnel to rush to the scene with a fast path, improving the efficiency of fire rescue.
