摘要： 针对换流变压器现有Box-in降噪结构对外部灭火救援有阻碍、遮挡作用，严重影响外部消防有效灭火的难题，通过试验研究换流变新型降噪板熔断脱落行为及其灭火过程，分析新型降噪板熔断过程对灭火效果的影响和高温热油火对Box-in内部固定消防系统管路的影响。试验结果表明，两种新型降噪板在火灾中能够熔断并掉落，为Box-in降噪装置外部的消防操作提供有利条件，但其灭火难度仍明显大于无遮挡火的情形，而且火灾过程的高温会导致固定消防支管明显改变方向，使覆盖目标错位，无法包络目标部位。

Abstract: The Box-in reduction structure outside the transformer has hindered and blocked the external fire fighting and rescue, which seriously affects the effective fire fighting. The melting behavior of the new noise reduction board (Box-in) and the fire extinguishing process in converter substation were investigated experimentally. The influence of the breaking process of the new noise reduction plate on the fire extinguishing effect and the influence of high temperature hot oil fire on the pipeline of Box-in internal fixed fire extinguishing system were analyzed. The experimental results showed that the two new noise reduction plates could fuse and fall in the fire, which provided favorable conditions for the external fire operation of the Box-in noise reduction device. However, the fire extinguishing difficulty was still significantly greater than that of the unshielded fire. The high temperature of the fire process would lead to the obvious change of the direction of the fixed fire branch, which made the cover target dislocation and could not cover the target part.

Key words: melting behavior, fire extinguishing, noise reduction board, converter substation
