Novel valve hall plugging structure and fire resistance checking method
The invention discloses a novel valve hall plugging structure and a fire resistance checking method, and relates to the field of direct-current power transmission. The structure is used for enhancingthe fire resistance and explosion resistance of a firewall between a converter transformer and a valve hall; the structure comprises a first plug and a second plug, a converter transformer sleeve on the converter transformer side penetrates through the first plug and extends to the valve hall side, and the second plug is arranged on the contact surface of the converter transformer sleeve and the first plug; the first plug is sequentially connected with a buffer energy absorption layer, an explosion-proof steel plate layer and a fireproof layer from the converter transformer side to the valve hall side; and the second plug comprises a ceramic silicone rubber waterproof sealing sleeve used for being arranged on the converter transformer sleeve in a sleeving mode and an aluminum silicate fiber needled blanket arranged between the contact faces of the converter transformer sleeve and the first plug in a filling mode. The method is used for checking the fire resistance of the structure. Thestructure can not deform or fail under the severe high-temperature combustion condition, and therefore valve hall equipment is protected against damage under the adverse condition that a transformerexplodes and is on fire.
本发明公开了一种阀厅封堵新型结构及耐火校核方法，涉及直流输电领域，所述结构用于加强换流变与阀厅之间的防火墙的防火防爆能力，其包括第一封堵和第二封堵，换流变侧的换流变套管穿过所述第一封堵伸出到阀厅侧，所述换流变套管与所述第一封堵的接触面设置有所述第二封堵；所述第一封堵从换流变侧到阀厅侧依次连接的缓冲吸能层、防爆钢板层和防火层，所述第二封堵包括用于套设在所述换流变套管上的陶瓷化硅橡胶防水密封套筒以及填充在所述换流变套管与所述第一封堵的接触面之间的硅酸铝纤维针刺毯。所述方法用于结构的耐火校核。本发明的结构能在苛刻高温燃烧条件下不变形不失效，从而实现在变压器爆炸起火的不利条件下保护阀厅设备不损坏。
