Reliability test method research of latching relay used in meter
摘要
Abstract
The reliability of latching relay in watt-hour meter has important influence on watt-hour meter quality and user electricity reliability .According to the features of latching relay used in meter , this paper proposes that mechani-cal reliability and electrical reliability adopt failure rate as its reliability characteristic quantity , the short circuit relia-bility adopts success rate as its reliability characteristic quantity , as a result, the reliability evaluation indices are clar-ified.The test environment and test method of mechanical reliability , electrical reliability and short circuit reliability are explained .On the basis of studying the sampling observation characteristics of failure rate and success rate , the test sampling scheme and test procedure of three kinds of reliability are put forward , and the test procedures of grad-ing, maintenance and upgrade are stipulated .Effect validation experiment shows that the reliability test method can effectively distinguish different quality reliability levels of the products .关键词
