Fault detection for equipment in distribution grid station house based on ubiquitous internet of things

The fault detection device for the equipment in distribution grid station house collects information such as line operation state, line load and voltage through the mobile phone APP and has a real-time detection of line faults to realize on-line monitoring and analysis of distribution lines, which enables the operation and maintenance personnel to know about the line working at any time and provides data support for line perception, early warning and prediction, and auxiliary diagnosis. As the edge facility under the ubiquitous Internet of Things, the fault detection device connects the smart grid and the data from the ubiquitous Internet of Things, which creates an open and innovative data application ecology and provides data services for lean management of the distribution grid. It meets the requirements of "Research on Key Technologies of Sensors and Research and Development of Equipment", one of the five key technical research projects of the State Grid on strengthening the construction of Internet of Things in Power Systems. It is innovative in micro-power wireless communication technology, sensor energy collection technology, weak signal filtering and calculation.
