Abstract

Abstract:

Ring network cabinet is an indispensable switchgear in power grid.Since ring network cabinet failure is most likely led by its mechanical characteristics,it is particularly critical to monitoring its characteristic parameters.In the study on the mechanical characteristics of a ring network cabinet,its hardware and software were analyzed,and online monitoring on the travel-time parameters,open-close time and other characteristic parameters was made,and the data were collected,uploaded and communicated based on Internet of Things technology.The experimental results show that the relative error of the data from the ring network cabinet monitoring system based on the Internet of Things is within an acceptable range,which indicates that the system can realize mechanical characteristics monitoring and fault alarm.The system is feasible.

Key words: Internet of Things, ring network cabinet, mechanical characteristics, online monitoring system, fault warning
