The utility model protects an explosion-proof structure of the firewall on the side of the UHV converter valve hall. A two-way opening single-layer push-pull door is arranged on the side of the valve hall and the converter side of the firewall sealing structure, and a two-way opening explosion-proof push-pull door is added on the outer side of the single-layer push-pull door on the converter side. The single-layer push-pull door and the explosion-proof push-pull door contain a hole for passing through the wall casing, and the explosion-proof The upper and lower ends of single-layer push-pull doors and explosion-proof push-pull doors are positioned and moved by sliding rails in the form of beam-plate structure with H-shaped steel as the framework. The upper and lower hinges are also arranged. The sealing structure is a Nano-mesoporous fire-proof thermal insulation board. The utility model adopts the combination of H-shaped steel and plate and strip as the explosion-proof door, and achieves explosion-proof function on the converter side to solve the fire and explosion of transformers. The stability of medium fire-proof plugging can avoid the spread of converter fire to the valve hall and ensure the safety of the valve hall. At the same time, nano-medium fire-proof material is used to plug the hole, which has better fire-proof and heat-insulation performance.
【技术实现步骤摘要】
特高压换流变阀厅侧防火墙封堵防爆结构
本技术属于输变电领域,是一种适用于特高压换流站阀厅封堵的技术。
技术介绍
目前国内发生多起特高压换流变爆炸事故,其中阀厅侧防火墙的封堵均被破坏,甚至有由于封堵被破坏导致阀厅烧坍塌的事故,损失严重。目前特高压换流站阀厅侧的防火墙的封堵由于均未考虑防爆措施,导致换流变起火事故中,初期的爆炸直接把防火封堵破坏,无法起到隔火的作用,存在极大的安全隐患。
技术实现思路
本技术所解决的技术问题即在提供一种特高压换流变阀厅侧防火墙封堵防爆结构。本技术所采用的技术手段如下所述。一种特高压换流变阀厅侧防火墙封堵防爆结构,在防火墙封堵结构的阀厅侧和换流变侧均设置双向开合的单层推拉门,在换流变侧的单层推拉门外侧加设双向开合的防爆推拉门,所述单层推拉门和防爆推拉门上均包含供穿墙套管通过的洞口,所述防爆推拉门以H型钢为骨架的梁板结构形式;所述单层推拉门和防爆推拉门的上、下端通过滑轨定位并实现推拉移动。防火墙封堵结构并排穿设2个穿墙套管,在防爆推拉门的洞口位置设置可分别向上、下收起的上、下合叶,推拉门打开时上、下合叶向上、下收起,推拉门闭合时上、下合叶拼合,拼合后防爆推拉门和上、下合叶将防火墙封堵结构遮挡,仅有穿墙套管穿过。所述单层推拉门为钢板推拉门,采用10mmQ345钢板。所述板带和H型钢采用奥氏体304不锈钢材。所述封堵结构为200mm厚的纳米介孔防火保温板,该纳米介孔防火保温板与防火墙角钢框之间的缝隙,采用耐火胶泥填充。本技术所产生的有益效果如下。1、本技术在特高压换流站变压器阀厅侧防火墙中的防火封堵中外侧增加了防暴措施,即采用H型钢和板带组合的 ...
