摘　　要：电弧故障保护电器的产品测试中,电缆碳化通道的质量直接影响试验效率以及试验结果的可靠性。然而电缆碳化通道的一致性较低、随机性较大,使得电缆碳化通道的成功率难以得到保证。提供了一种提高电缆碳化通道成功率的方法,将碳化通道电缆制作过程中的切割步骤加以研究分析,将无法精确测量的爬电距离量化为适当的弯折角度,并通过测量第二步碳化中特定条件下流过碳化通道的电流(以下称判定电流)大小来表征标准中停止冒烟的现象,两种量化指标数据互相印证。通过所提方法找出对应的弯折角度以及判定电流就能提高电缆碳化通道的成功率,从而提高测试效率。In the product verification and certification test of arc fault detective device,the quality of cable carbonization has impact on the efficiency of test significantly. The success rate of carbonization can not keep in a high level due to the randomness of cable making. This paper provided a way to increase the success rate of cable carbonization. After research into the step of cable making the paper replaces the creepage distance which is hard to measure with appropriate bending angle,and represents stop smoking in carbonization by specific criteria current through carbonization path. These two values prove each other correlatively so that we find a way to increase the success rate of cable carbonization.
