Problems solved by technology

[0005] 2. Produce a large amount of toxic gas; on the one hand, the outer sheath material of the cable will produce a lot of toxic gas under the high temperature conditions of the fire. When the concentration of toxic gas is greater than the concentration that people can bear, it will cause poisoning symptoms to the personnel It will add difficulty to the rescue work of firefighters; on the other hand, toxic hydride gas will combine with water vapor to form acid substances, which will adhere to the surrounding electrical equipment, causing electrical equipment to be corroded to a large extent, equipment and wiring There is a downward trend in the insulation of the circuit;
[0006] 3. Affect visibility; visibility directly affects the evacuation of people around the cable trench under fire conditions, as well as the rescue and firefighting work of firefighters. During the fire development process, some smoke particles will be produced to block visible light; on the other hand, toxic gases have Stimulating, shortening the visible distance of people

Abstract

The invention discloses a transformer substation electrical equipment fire hazard residue detection and analysis system. The system comprises a WRF-ARW meteorological field simulation unit for collecting and analyzing meteorological and topographic data near a transformer substation and a CALPUFF simulation unit for collecting and analyzing flue gas mixture data after a transformer substation electrical equipment fire hazard. Pollutants in atmospheric sedimentation are subjected to source analysis by adopting a positive definite matrix factorization (PMF) model by analyzing toxic and harmful pollution conditions and spatial distribution characteristics in the atmospheric sedimentation of the transformer substation. Through the transformer substation electrical equipment fire residue detection and analysis software, the transformer substation electrical equipment fire residue detection and analysis can achieve an accurate evaluation effect.

Description

technical field [0001] The invention relates to an electrical equipment management system, in particular to a detection and analysis system and analysis method for electrical equipment fire residues in substations. Background technique [0002] As we all know, the substation is a hub in the power system, which exchanges voltage and current, and is a place for receiving and distributing electric energy, which can be seen everywhere in the city. Once a fire occurs in a substation, it will threaten the normal operation of the entire power grid system and the reliability of power supply. Therefore, taking good fire prevention measures in the substation will help ensure the safe and stable operation of the power grid system. However, due to the aging of the substation facilities or the influence of the external environment (such as typhoons, rainstorms, lightning, etc.), arcs or short-circuit sparks will destroy nearby combustible materials. Steam and dust ignite, causing fire, ...
