Description

Technical Field

[0001] This utility model relates to the field of measurement switch technology, specifically to a measurement switch based on a topology recognition circuit. Background Technology

[0002] A measurement switch is a low-voltage switching device equipped with a high-precision current sensor and measurement unit. It is used to perform normal connection and disconnection of power distribution lines, or overload and short-circuit protection functions. It also enables local or remote data exchange and can monitor node voltage, current, and energy, as well as perform segmented and refined processing. It is a crucial underlying node component for realizing smart grids. Traditional measurement switches mainly perform on / off operations based on preset parameters and cannot adjust their strategies according to changes in circuit topology. When the circuit topology changes, malfunctions are prone to occur, resulting in poor accuracy and flexibility in control. Furthermore, traditional measurement switches cannot autonomously identify the circuit topology; topology identification relies on manual intervention or other independent systems, preventing control decisions from being optimized for the current topology and making it difficult to adapt to complex dynamic changes in circuits.
