| 摘 要： | 针对绝缘结构在实际使用过程中受到综合应力因素的影响的特点,提出了一种基于综合应力的绝缘结构可靠性评估方法,可以有效地指导绝缘结构加速寿命试验的设计和实施。首先通过对绝缘结构进行失效机理及应力分析,确定影响绝缘结构寿命的主要应力,选取适当的综合应力加速模型。其次,确定各加速应力水平,进行综合应力加速寿命试验方案的设计。最后,基于失效数据对绝缘结构进行可靠性评估。

| Abstract: | According to the characteristics of insulation system affected by various stresses in actual use, a reliability assessment method based on multi-stress accelerated model is proposed, which can be used as a guide for design and application of accelerated life test for insulation system. Firstly, the main stress that affects the life of insulation system are determined through the analysis of the failure mechanism, and the multi-stress accelerated model is properly selected. Secondly, the accelerated stress levels are determined and the accelerated life test of insulation system is designed. Finally, reliability assessment is carried out based on the failure data of the insulation system. |
