摘要：

为了提升新建特高压换流站阀厅的安全性能，提出了1 种兼顾防火与抗爆的新型封堵系统，在碳氢升温曲线下对5m×5.2 m 封堵系统真型样品进行了耐火试验，建立了封堵结构的抗爆性能数值分析模型，计算了典型爆炸工况下新型封堵结构的动力响应过程。结果表明，新型防火抗爆封堵系统在碳氢升温曲线下耐火极限大于3 h,在设计爆炸荷载作用下处于弹性状态，不影响系统防火性能。

Abstract:

In this paper, a new type of stopping system that takes into account both fire and blast resistance is proposed in order to improve the safety performance of the valve hall of the newly built UHVDC converter station. The sample stopping system with a size of 5 m × 5.2 m is conducted under the hydrocarbon fire curve, and a numerical analysis model for blast resistance performance of the stopping structure is established to calculate the dynamic response process of the new stopping structure under typical explosion conditions. The results show that the new blast and fire stopping system proposed in this paper has a fire resistance rating of more than 3 hours under the hydrocarbon fire curve. Meanwhile, the new stopping structure is in an elastic state under the designated blast loading and does not affect the fireproof performance of the system.
