Relay Aging and Reliability Analysis of Nuclear Power Station

摘要: 通过对LEACH继电器的老化失效及可靠性分析实验,得知1999年批次继电器失效的原因,是由于线圈绝缘材料中增塑剂氧化变质而导致的绝缘性能下降和发热量增加,并有针对性地提出了继电器老化的外壳温度监测方法,制定了批次更换措施。

Abstract: Based on the analysis and test of the aging failure and reliability of LEACH relays produced in 1999,it was realized that the failure is due to the resistance decrement and heat generation caused by insu-lation material degradation.Measuring the outer shell temperature can monitor the aging process.For the unreliable batch,it is necessary to start the batch replacement program.
