Blazing sun in the sky, high temperature red warning signals frequently screen, the temperature all the way "wildly", many areas of the outdoor temperature of more than 40 ℃, Hebei, Shandong, Inner Mongolia and other places of the surface temperature even more than 70 ℃! Field interpretation of "hot to hot jio". With this week officially entered the "three days", high temperature is every day "card".
Continuous high-temperature weather, we can feel the preciousness of each degree of electricity, which also gives to the power line work to bring severe "baked" test, such as mountain fire hazards, last summer, Sichuan and Chongqing high temperatures, forest fires are also in a short period of time to focus on the occurrence.
During the summer heat, the characteristics of forest fires mainly include the following aspects:
1, dry conditions: summer and summer heat period, which makes the forest vegetation and dead fallout dry up, dry conditions increase the risk of fire and spread of fire, the probability of wildfires is greater!
2, strong winds fuel the fire: wind can fuel the spread of fire. Strong winds can not only quickly expand the fire, but also take away the sparks, so that the fire jump spread.
3, mountainous terrain: many forest fires occur in the mountain forest area, this terrain is complex and undulating, fire blockade and control is more difficult.
4, fuel accumulation: vegetation and dead fallout of combustible material within the forest.
5 , human activities: people carry out outdoor activities, improper wildfire, fireworks have also become one of the causes of forest fires.
In view of the characteristics of forest fires during the high temperature in summer, appropriate preventive and control measures should be taken. Especially near the overhead high-voltage lines, pylons and other power facilities and equipment in the forest area, it is necessary to stand solar voice warning poles, power pylons to install transmission lines to prevent hill fires on-line monitoring device (our transmission lines to prevent hill fires on-line monitoring device of the dual-spectrum + video monitoring module, real-time discovery of the channel smoke, open fire fire, visualization of the automatic alarm back to the rapid completion of hundreds of thousands of kilometers of power transmission line remote (line patrol).
The following picture is the scene of 2023.7.11, a 220kv line in Beihai installing Dingsin Wisdom Technology's hill fire monitoring device:
