The invention relates to a device and method for achieving reclosing non-voltage check, and aims at solving the technical problem that protection of reclosing non-voltage check cannot be effectively achieved under the condition of connection of distributed power supplies in an existing power transmission line system. An output node of a live display device is connected to a reclosing protection device, and an input quantity of the live display device is taken as a judgment condition of a reclosing action logic. The device and the method can be widely used for a power system.
