变加速因子的低压熔断器寿命评估方法

Lifetime Evaluation Method of Low Voltage Fuse Based on Variable Accelerated Factor

基于熔断器加速老化试验的特点,提出了一种变加速因子的熔断器寿命评估方法。该方法能够更加准确、有效地评估熔断器的寿命信息。最后,以某熔断器为例进行了试验,将恒定加速因子与变加速因子2种方法的评估结果进行对比,表明了该方法的有效性。

A lifetime evaluating method of variable accelerated factor was proposed based on the characteristic of accelerated ageing test for fuse.The method,compared with the method of constant accelerated factor,was more accurate and effective to evaluate fuse’s lifetime.Two methods based on the constant accelerated factor and variable accelerated factor were used to evaluate the lifetime of a type of fuse,and the results were compared to confirm the effectiveness.
