换流变压器阀厅抗爆门抗冲击性能实验研究

Experimental Study on Anti-shock Performance of Explosion-resistant Door of Converter Transformer Valve Hall

抗爆门作为换流变压器阀厅的重要安全防护设施,有着很高的质量要求,因此对阀厅抗爆门的抗冲击性能研究具有很大的实用价值。主要对300 kPa和1000 kPa冲击波超压载荷工况下,有泡沫铝填充和无填充的抗爆门抗爆性能进行实验研究,验证抗爆门的抗冲击性,并通过门扇形变量对两种不同材质抗爆门的抗爆性能进行对比评估。实验结果表明:有泡沫铝填充的抗爆门在300 kPa和1000 kPa强度冲击波情况下,面板最大变形量为分别为2 mm和3 mm,与不带填充的抗爆门相比,抗冲击性能明显提高,且随着爆炸载荷的增加,其抗冲击性能提升越显著。

As an important safety protection facility of converter transformer valve hall,the explosion-resistant door should meets high quality requirements.Therefore,it is of great practical value to study the anti-shock performance of the explosion-resistant door of the valve hall.The anti-shnock performance of the explosion-resistant door filled with foam aluminum and nothing filled was studied and verified experimentally under the shock wave condition of 300 kPa and 1000 kPa,respectively.The anti-shock performance of the two different doors was evaluated through the amount of deformation,whose maximum values turned out to be 2 mm and 3 mm.The experimental results show that the explosion-resistant door with aluminum foam filling has better anti-shorck performance under higher loadings.
