Embodiment 1

[0049] This embodiment provides a specific operation steps for controlling aviation devices based on the collaborative control method of insulation and anti-evaporation performance of aviation fire extinguishing:

[0050] First of all, a fire broke out under the #43 tower of the 220kV Zilian II Line.

[0051] Through the PMS system, it is found that the height of the conductor of the transmission line section to the ground is 13m; the safety distance corresponding to 220kV is 3m, therefore, the height of the envelope conductor section is in the height range of 13-16m; the flight speed of the aviation fire extinguishing device is 13.8 m / s, the spray flow rate is 80L / s, the 34m between the initial flying height of 50m and the 16m of the enveloping wire section is the anti-evaporation section; the wire pair section is a height range of 0-13m.

[0052] Then, calculate and obtain the temperature curve of the fire scene as follows: Figure 4 shown. The temperature is 150°C at 12m ...

Abstract

The invention provides an insulation and evaporation prevention performance cooperative control method and system based on aviation fire extinguishing. The method comprises the steps that the height of wires of a power transmission line section of a mountain fire scene to the ground is obtained, and a falling water body of a fire extinguishing agent is divided into an anti-evaporation section between an initial flying height of an aviation fire extinguishing device and the wires, an enveloping wire section and a wire grounding section according to the height of the wires to the ground; the temperatures of high-temperature smoke plumes of the mountain fire scene at different heights is calculated, the heating temperature of the fire extinguishing agent in the falling process of the anti-evaporation section is calculated according to the set boundary conditions of heat exchange between the fire extinguishing agent and the high-temperature smoke plume of the fire scene, and the average diffusion degree of the fire extinguishing agent in the enveloping wire section when the fire extinguishing agent falls to the height of the wire to the ground is calculated; the relation between the heating temperature and an anti-evaporation system failure temperature threshold value as well as the relation between the average diffusion degree and an insulation critical diffusion degree are judged; and the flight height of the aviation fire extinguishing device is adjusted according to the relations.

Description

technical field [0001] The invention relates to the technical field of mountain fire prevention and control for power transmission lines, and specifically discloses a method and system for synergistic control of insulation and anti-evaporation performance based on aviation fire extinguishing. Background technique [0002] In recent years, due to the continuous drought and the impact of the production and life of residents near the transmission line, wildfire accidents in the transmission line corridor have occurred frequently, seriously threatening the safe and stable operation of the power grid. [0003] The use of helicopters to extinguish fires is not restricted by external conditions such as road blockage on the ground, and can quickly reach the fire scene for fire extinguishing. However, the scene environment of the transmission line mountain fire is complicated, and the fire extinguishing agent used for aviation fire extinguishing depends on the experience of the pilot...
