户内变压器火灾烟气及温度时空发展特性研究
Study on the Spatial and Temporal Development Characteristics of Fire Smoke and Temperature in Indoor Transformer
摘要
Abstract
Water spray system is an important means for fire suppression of transformer.As for the transformer cham⁃ber equipped with water spray system,in this paper the FDS software is used to conduct numerical simulation re⁃search on the development of the fire in transformer chamber under the action of spray,and obtain the temperature variation and soot generation as well as distribution during the fire development process.The results show that in case of no spray the maximum temperature of observation point 1 in the combustion zone can reach 966℃,then grad⁃ually decreases and finally fluctuates around 500℃.The soot generated by combustion firstly accumulates at the top of the transformer chamber,then spreads around,and at last gradually diffuses throughout the entire transformer cham⁃ber.The role of the spray is mainly reflected in reducing the heat release rate and temperature at the same time during the fire process,but it has little effect on the indoor smoke plume movement.The motion of spray droplets is close to that of soot.The temperature near the wall of the transformer chamber is mainly affected by the diffusion of soot.关键词
