摘要

换流变压器的燃弧故障会导致变压器损坏甚至引起邻近的变压器或其他电气设备损坏，对变电站造成严重的破坏，影响到电网的安全稳定运行。文中针对换流变压器的薄弱环节—升高座内部的燃弧故障，采用数值仿真计算开展了换流变压器升高座内部故障条件下的故障特征研究，分析了升高座内部不同燃弧能量下的升高座筒身等效压力及应力分布，指出在电弧能量的情况下，通过加强器壁材料性能不能起到有效地抗爆作用，需要研发有效地泄压措施。

Abstract

The arcing fault of converter transformer will lead to damage to transformer and even to adjacent transformers or other electrical equipment

which will cause serious damage to substation and affect the safe and stable operation of the power grid. Aiming at the weak link of the converter transformer

namely arcing fault inside the elevated seat

the numerical simulation is used in this paper to perform the fault characteristics study under the internal fault condition of the converter transformer elevated seat

analyze the equivalent pressure and stress distribution of the elevated seat under different arcing energy of elevated seat. It is pointed out that under the arc energy enhancing the material properties of the wall can not achieve anti-explosion effects and it is therefore necessay to develop effective pressure relief measures.
