Grid adaptability detecting device capable of working at full power under voltages of 35 kV and 10 kV

The invention discloses a grid adaptability detecting device capable of working at full power under voltages of 35 kV and 10 kV. The device comprises an input transformer module, a converter module and a boosting transformer module which are sequentially connected. The input transformer module that reduces different grid voltages to be at the same levels and then outputs the reduced voltages to the converter module includes a first input transformer and a second input transformer; when the input transformer module is connected to the 35-kV grid, primary windings of the first input transformerand the second input transformer are connected in series and are connected to be in a star shape; and when the input transformer module is connected to the 10-kV power grid, primary windings of the first input transformer and the second input transformer are connected in an angular shape and are connected in parallel. On the basis of the two kinds of connecting structures, the grid adaptability detecting device can work a
