Introduction: Overhead transmission lines are an important part of the power grid and carry a huge amount of power. The safety of the lines is closely related to the stability of the power grid. However, with the continuous development of the afforestation business, the area of ​​forest land and the stock of forestry have increased year by year. The prevention of mountain fires is the primary task.
According to the high season of mountain fires, they are mainly concentrated on:
(1) The vegetation is dry at the end of winter and early spring, and the weather turns sunny and warm, and there is little rain and dryness;
(2) Before and after the Ching Ming Festival, it was concentrated during the ancestral graves;
(3) During the late autumn and early winter, when the weather is dry and windy, farmers are also burnt.
The dry and windy weather in spring and autumn is a period of high forest fire risk. With the arrival of Ching Ming Festival, burning of wasteland, burning of ancestors, burning of firewood, burning of sundries, and other reasons can easily cause mountain fires. The power facilities are protected against fires and fires. Faced with a grim situation. Once a fire has occurred, it must be taken extremely quickly to take measures to save the fire. Whether or not the fire is timely and the decision is appropriate depends on whether the discovery of the forest fire is timely. Therefore, a transmission line anti-fire monitoring system is particularly important.
The on-line monitoring system for the transmission line against hill fire consists of two parts, front-end equipment and back-office software. The transmission line mountain fire monitoring device integrates an infrared thermal imaging unit, an over temperature detection unit, a visible light imaging unit, a fire monitoring and analysis unit, a micro weather monitoring unit, a pan-tilt precision positioning unit, an audible and visual alarm unit, a video compression unit and a wireless communication unit And the power system and other components. Can output two video signals at the same time, with infrared thermal imaging over-temperature detection and visible light fire detection capabilities, and can be analyzed according to the confidence factor model, automatically give fire alarm information.
The State Grid Power Supply Company has made the prevention of mountain fire, fire prevention, and external defense damage under the line as the current key work. It has installed a transmission line anti-fire protection system to ensure that early warning of hill fire hidden dangers is prevented and the safe and stable operation of the power grid is guaranteed.
The forest fire may cause tripping of the line and cause serious impact on people's lives and production. Therefore, the power supply company should further increase the efforts in preventing fires on the transmission line and prevent external breakage, and actively implement early prevention, early detection, and early processing to ensure protection. The hidden dangers of transmission lines are controlled and controlled to ensure the safe and stable operation of the power grid.
