摘　　要：研究了电力系统继电保护装置可靠性的特征量、评估方法并设计了高加速寿命试验的方法。通过对几种典型装置的环境因素的影响试验,得出试验的结果,以此来分析不同因素的影响程度。提出了继电保护装置高加速寿命试验宜选用的应力极限,并探讨了高加速寿命试验的特征量与正常环境下特征量的换算方法。This paper studied the characteristic amount and evaluation method of reliability in relay protection devices of power system, designing the highly accelerated life test method. The test results were got by the influence tests of environmental factors for several typical devices, so as to analyze the influence degree of different factors. The stress limit were selected for the highly accelerated life test of relay protection devices and discussion was made on the conversion method from the characteristic amount of the highly accelerated life test to the characteristic amount of normal environment.

关 键 词：继电保护装置 高加速寿命试验 可靠性
