Abstract

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.
