中文摘要: 随着电子设备复杂程度越来越高,电子设备的可靠性要求也越来越突出。由于影响电子式电能表不运行的因素比感应式电能表更多更复杂,对电子式电能表的可靠性提出了更高的要求。通过分析电子电能表可靠性评估技术的发展现状及存在的问题,结合电能表自身的技术特点及可靠性评估技术要求,提出了加速寿命试验和元器件应力法两种预测方法,这两种方法是开展电子式电能表可靠性预测的最实用、最具理论价值和工程应用价值的技术方法,有利于电力企业选用更高可靠性、长寿命的电子式电能表,大大降低电力系统经营运行成本。
Abstract:With the increasing complexity of electronic equipment, the reliability of electronic equipment is becoming more and more prominent.Because the factors that affect the non-operation of electronic energy meter are more and more complex than the inductive power meter, the reliability of the electronic energy meter is higher.This paper analyzes the electronic watt-hour meter reliability evaluation technology development present situation and existing problems, combined with the technical characteristics of watt-hour meter and reliability assessment of technical requirements, proposed the accelerated life test and the component stress method two kinds of forecasting method, the two methods is the most practical reliability prediction of electronic watt-hour meter, most theoretical value and engineering application value of technical methods and is helpful for the electric power enterprise to choose higher reliability, long service life of electronic watt-hour meter, electric power system operation cost is greatly reduced.
