换流变压器有载调压开关防爆试验研究与分析

Gaoya dianqi
为研究有载调压开关的防爆能力，以换流变压器有载调压开关为研究对象，搭建了有载调压开关的防爆试验系统。在开关内部设置了一对电极，当试验大电流通过电极之间的细小铜丝使其发生熔断后，电极之间形成电弧通道。通过调整电弧电流、电弧间距、燃弧时长，从而获取了不同故障能量并测量了在此能量下的开关内的压力。计算并对比了在对应能量下开关油室的压力。试验研究表明：①开关的防爆能力有限，建议提高开关盖板强度，结合爆破膜对开关进行防爆；②为避免随着电弧能量增大使弧压变化过大，建议减小电极间距；③为避免电极烧蚀，建议使用比热容小、

封闭容器内部短路燃弧金属烧蚀对热—力效应的影响分析

Gaoya dianqi
金属封闭开关设备内部发生短路燃弧故障时，电弧烧蚀金属材料生成的金属蒸气是影响热—力效应的重要因素之一，但目前仍缺乏金属烧蚀量对热—力效应影响的定量研究。基于磁流体动力学（MHD）理论与金属蒸气的质量浓度方程，建立了考虑金属烧蚀的短路电弧数学模型，并在计算模型内部放置带孔金属板，通过改变金属板孔径大小控制金属烧蚀量，以定量评估金属烧蚀量对封闭容器内部短路燃弧产生的热—力效应的影响。结果表明：铜、铁金属板孔径越小，金属烧蚀量越大，封闭容器内压力升与最高温升越低；相同孔径下，铜金属板蒸发质量高于铁金属板 ...
