摘要 基于数学公式的电弧失效影响模型中的未知参数需要依据数据求取,利用Ansys CFX与Mechanical APDL分析了航空直流28V和交流115V电压下的并行电弧故障发生时,其能量在周围管路上的温度分布情况,并提取分析数据,计算电弧失效影响模型参数。运用类比法证明了模型计算结果的正确性,能够利用该模型预测电弧发生后对其他物体的损伤。 The unknown parameters in arc damage modeling based on mathematical formulas need to be obtained. The temperature of the pipeline around is analyzed when parallel arc faults occur at DC 28V and AC l15V circuit with Ansys CFX and Mechanical APDL. The result is extracted to calculate the model parameters. Analogy is used to show the correctness of the model and the applicability of arc damage predication to other objects around.
