Fire patrol and fire extinguishing system for transformer substation and fire extinguishing method of fire patrol and fire extinguishing system

Abstract

The invention provides a fire patrol and fire extinguishing system for a transformer substation and a fire extinguishing method of the fire patrol and fire extinguishing system. The fire patrol and fire extinguishing system for the transformer substation comprises an autonomous positioning navigation obstacle avoidance unit, a water mist fire extinguishing unit, a walking control unit, a sensing control unit and a power supply unit. Regular patrol is carried out on a predetermined area, and the surrounding environment is scanned through an infrared double-vision thermal imaging module. When afire is found, a master control module sends out an alarm signal, analysis is carried out through image data, and a fire scene area and a fire source area with the highest temperature are determined.If the maximum distance between the fire source area and the boundary of the fire scene area is smaller than or equal to 1 m, fire source fire extinguishing is executed preferentially. If the maximumdistance between the fire source area and the boundary of the fire scene area is greater than 1 m, diffusion-prevention fire extinguishing is executed preferentially, and then fire source fire extinguishing is carried out. When the surface temperature of an object ranges from 30 DEG C to 100 DEG C, fire extinguishing on the area is stopped. After fire extinguishing is completed, patrol continues to be carried out. Through the arrangement, the fire patrol and fire extinguishing system for the transformer substation has extremely high fire extinguishing efficiency, and meanwhile secondary damageto electronic equipment cannot be generated in the fire extinguishing process.

Description

technical field [0001] The invention relates to the field of substation maintenance, in particular to a substation fire inspection and fire extinguishing system and a fire extinguishing method thereof. Background technique [0002] Most substation fires are caused by accumulated heat. Therefore, in addition to perfect monitoring devices for fire prevention, an effective cooling auxiliary system with low collateral damage is also particularly important. [0003] The substation plays an important role in the whole power consumption field, and the fire prevention of the substation becomes very important. At present, the fire extinguishing methods that are widely used in substations are mainly heptafluoropropane fire extinguishing system, carbon dioxide fire extinguishing system and fixed water spray fire extinguishing system. However, the above-mentioned fire extinguishing technologies have certain deficiencies when they are applied to substations. When using heptafluoropropan...

AI Technical Summary

Problems solved by technology

However, the above-mentioned fire extinguishing technologies have certain deficiencies when they are applied to substations. When using heptafluoropropane to extinguish the fire, heptafluoropropane will produce acidic substances in a hot state, which will cause secondary damage to the equipment in the station, and the smoke generated in the fire is harmful to electronics, Stain loss from electrical equipment is high

Although the carbon dioxide gas fire extinguishing system is not corrosive, it also has a good protective effect in a confined space, but it requires the preservation of high concentrations of toxicity and release at low temperatures, which will cause serious harm to electronic equipment and staff in the station

The fixed water spray fire extinguishing system cannot achieve full area coverage due to layout restrictions, and the fire extinguishing efficiency in special areas such as valve halls and reactors in converter stations is often low
