换流变阀侧套管防火墙洞口封堵抗冲击结构研究

A Study on Shock Resistance Structure of Firewall Hole Sealing of Side Casing on Converter Valve

换流变压器发生严重故障时,由于压力瞬间增大,可能会引起爆炸,对周围设备造成不可逆的破坏,尤其是可能破坏阀厅封堵,对阀厅内设备产生严重的破坏,造成巨大的经济损失。换流变压器防火墙洞口抗冲击结构能在不影响换流变压器正常运行的情况下,保护阀厅封堵的完整性,免受爆炸冲击的破坏,将爆燃事故造成的损失限制在最小的范围内。

When the converter transformer has a serious failure,due to the instantaneous increase in pressure,it may cause an explosion,causing irreversible damage to the surrounding equipment,especially it may damage the valve hall blockage,causing serious damage to the equipment in the valve hall,causing huge economic loss.The impact-resistant structure of the firewall opening of the converter transformer can protect the integrity of the valve hall blockage without affecting the normal operation of the converter transformer,avoid the damage of explosion impact,and limit the loss caused by the deflagration accident to a minimum.
