  • Current limiting device, current limiter and current limiting system for power grid
    Patent number: 9640984
    Abstract: A current limiting device for a power grid includes a first current limiting reactor; a first smart fast switch connected with the first current limiting reactor in parallel; a current transformer sleeved on a bus bar located on one side of a circuit resulting from the parallel connection of the first current limiting reactor with the first smart fast switch to monitor the current in the bus bar in real time; and a controller connected with the current transformer to control the switch-off of the first smart fast switch when the current in the bus bar is higher than a first preset value and the switch-on of the first smart fast switch when the current in the bus bar is smaller than a second preset value, wherein the first preset value is higher than the second preset value. The current limiting device improves the operational reliability of a power grid.
