Study of Electric Parameter Test Methods and Failure Mechanism for the Opticalcoupler

Abstract

Photoelectric coupler (abbreviation as Opticalcoupler) is a signal devices that the impaction is to provide input and output isolation transmission, and it is the main components of the smart meter. Once the Opticalcoupler is out of operation, it will lead to be unable to communicate et al, so it can affect the power system security and the interests of all parties. In this paper it was introduced of the main technical parameters of the Opticalcoupler used to the smart meter. The main facts of the electric stress, mechanical stress and environmental stress factors was analyzed that affected the failure of the Opticalcoupler in the design and use of the smart meter, according to the result and time parameter test methods were emphatically introduced. The paper can provide the basis for relevant selection and testing of Opticalcoupler.
