Comprehensive evaluation of reliability life and economy of electric energy meter considering intermittent operation mode

In the application process of smart electric energy meter, not all components are in working state all the time. According to the working stress to predict its reliability index will lead to the conservatism of the predicted results. Therefore, it is necessary to consider the non-stress state of the intermittent mode unit, so as to make a more reasonable and accurate prediction. In this paper, a reliability prediction method considering non-stress state of components in intermittent operation mode is proposed, and a practical reliability prediction model of electric energy meter is established, which realizes the accurate reliability prediction of intelligent electric energy meter in intermittent mode. Based on the theory of reliability prediction and life cycle cost of electric energy meter, a comprehensive evaluation model of reliability and economy of smart electric energy meter is established, which provides a theoretical basis for the formulation of reliability index and related management policies of smart electric energy meter.
