Development of a Sensing Device for Multi-branch Station Areas in Low-Voltage Distribution Networks

In response to the issues of large monitoring blind spots, difficulty in fault localization, and time-consuming manual line inspection during fault patrols in low-voltage distribution network multi-branch station areas, a novel sensing device for such areas has been developed. This device draws on the networking technology of household routers and the data-sharing mechanism of cloud platforms. It adopts a modular design combining distributed monitoring terminals and centralized data aggregation units, featuring real-time monitoring at the branch level, active fault warning, and multi-end information synchronization. Practical application demonstrates that the device achieves comprehensive perception of complex station areas, significantly reduces the average fault detection time in low-voltage distribution networks, and enhances operational efficiency and power supply reliability.
