摘 要：介绍了国内外开展交流接触器可靠性研究概况，阐述了机床用交流接触器机械操作可靠性试验方法与评估方法。指出交流接触器通断实际电气负载时产品失效分布类型为威布尔分布，失效率不是常数，不宜采用失效率大小作为交流接触器通断实际电气负载时的可靠性指标，而应采用可靠性测定试验，并给出了交流接触器通断实际电气负载时可靠性试验方法与提供可靠性数据的评估方法。

Abstract: Introduction was made to AC contactor reliability study development situations both at home and abroad. This paper described the reliability test method of machine tool used AC contactor mechanical operation and the evaluation method, pointing out that the product failure distribution type is Weibull distribution when AC contactor turning on/off the rating electrical load, failure rate is not constant, it is not suitable to adopt failure rate value as reliability index, but to adopt reliability measurement test, and the corresponding methods were given.
        Key words: AC contactor; reliability index; reliability verification test
