摘要/Abstract

摘要： 通过对特高压换流变Box-in降噪装置布置特点、火灾危险性和常用灭火技术的分析，揭示了现有Box-in降噪装置对特高压换流变灭火效果和火势发展的影响。结合新型热熔降噪材料系列检测结果，提出了一种融合新型消防模块、热熔支撑板、防坠网、泄爆口的新型降噪设计方案，并通过全尺寸试验验证了其在换流变火灾场景下的熔断有效性。试验结果表明，新型消防模块和热熔支撑板在火灾情况下均能快速有效脱落，脱落时间小于2 min，脱落后的消防模块呈小碎块状，不阻挡和干扰消防介质有效灭火。该新型降噪设计方案能够为外部消防灭火提供有利条件，显著降低爆炸冲击对内部固定消防系统可能产生的损坏，同时因新增加功能带来的价格上涨幅度较小。

Abstract: Based on analysis for the arrangement characteristics of Box-in noise reduction device of UHV converter transformer, fire risk and common fire extinguishing technology, the influence of Box-in noise reduction device on fire extinguishing and fire development of UHV converter transformer was explained.Combined with the series test results of new hot melt noise reduction materials, a new noise reduction design scheme integrating new firefighting modules, hot melt support plates, anti-falling nets and explosion vents was proposed. The effectiveness of the design was verified by full-scale tests. The test results showed that the new firefighting module and hot melt support plate can quickly and effectively fall off under fire conditions, and the falling time was less than 2 min. The firefighting module after falling off was small and fragmentary, and the firefighting medium was not blocked and interfered. The new noise reduction design scheme can provide favorable conditions for external fire extinguishing, and significantly reduce the damage that explosion shock may cause to the internal fixed fire extinguishing system. At the same time, the price rise of the new noise reduction design scheme due to the new added function was acceptable.
