摘要
阐述了低压断路器和漏电保护电器等低压保护类电器可靠性研究的重要性、科学意义及其社会效益,介绍了国际上权威学术机构IEEE在该方面所做工作的概况,指出了开展该方面研究工作的难度与创新意义;重点分析讨论了低压断路器和漏电保护电器的故障模式,在此基础上,在国内外首次提出了其可靠性指标与可靠性验证试验方案,为我国电器行业开展低压保护类电器的可靠性工作提出了理论依据与具体方法。
This paper expounded the importance of reliability study on low-voltage circuit-breakers and residual current operated circuit-breakers, introduced the general situation of their reliability study carried out by the international authoritative academic academy IEEE and pointed out the difficulty and significance of the research work on these aspects. Then this paper discussed the failure modes of low-voltage circuit-breakers and residual current operated circuit-breakers, and provided their reliability indexes and reliability compliance test plans at the first time, which provided a kind of theory and method for the reliability research work of low-voltage protective electrical apparatus carried through in Chinese electrical apparatus industry.
