摘　　要：分析了接触器式继电器的工作特点和失效模式。接触器式继电器是频繁操作的控制电器,主要发生触头断开不良和触头接触不良两类故障。针对其工作特点和失效模式,参考国内外标准提出了接触器式继电器的可靠性检测方法,进行可靠性检测装置的研究,以实现其可靠性的定量分析。The operational features and the fault modes of contactor relay were analyzed. The contactor relay is frequently-operated control electrical apparatus and has two kinds of failures, poor contact and poor break. Based on its operational fearures and the fault modes and refered the international and national standards of electrical apparatus, the measure method of contact relay＇ s reliability was provided. The instrument was designed to measure the reliability level of contactor relay.

关 键 词：接触器式继电器 可靠性 失效模式
