On September 27, 2022, at 30 ℃ at noon, the sun was blazing hot, but there were people working on and under the Wuzhou 110kv power tower. "It was reported that a photoelectric composite temperature sensor was installed." So far, the installation of Dingxin Smart DX-WPS100-SH mountain fire monitoring device for 6 lines has been successfully completed!

According to the forest coverage monitoring results of the whole region in 2021 released by the Forestry Bureau of the Autonomous Region, Wuzhou has the highest forest coverage rate in the region. While protecting forest resources for the benefit of the public, the density of vegetation in the transmission line channel is also increasing. There are many dry trees, weeds and other combustibles in the forest, which virtually increases the pressure on hidden dangers of mountain fires. Every year, there are hidden dangers of transmission line fires in China. These fires are mainly caused by burning wasteland and sacrificing. During the Qingming Festival, Chongyang Festival and other festivals, mountain fires are more serious; Some mountain fires are caused by short circuit and high temperature of transmission lines, which produce metal slag and ignite combustibles.

The fire is merciless, spreads fast and covers a large area. Mountain fires have occurred in the forest area. The overhead transmission lines and towers of the power grid in the forest area cannot avoid the erosion of mountain fires. Tower collapse, burning, tripping and even forced emergency shutdown may occur, which has a huge impact on the normal operation of the power grid.

Take precautions. Just like the example we saw at the beginning, we can timely install a mountain fire prevention monitoring device, which integrates the image video and photoelectric composite overlapping temperature measurement technology to achieve real-time detection of the target fire source in the line corridor and image video feedback around the clock, and automatically alarm the operation and maintenance personnel about the mountain fire location and on-site fire conditions through apps and WeChat. According to the fire situation, the operation and maintenance personnel can respond in a timely manner, Fire fighting measures shall be taken.

Shenzhen Dingxin is committed to maintaining the safety of power facilities. At present, DX-WPS100-SH anti mountain fire monitoring device has been installed and enabled in many domestic lines, helping the power sector to achieve early response to grid mountain fire and ensure power security
