Abstract

The invention relates to the field of reactor fault simulation, in particular to a single-phase double-column paralleling reactor fault simulation device and method, a device body is of a double-silicon-steel-sheet iron core column structure, a winding is wound on the column, and iron yokes are arranged on the periphery of the column. The iron core column is pressed by a pressing bolt at the top of the transformer body; the upper iron yoke, the lower iron yoke and the side iron columns are fastened through U-shaped steel clamps and clamping bolts, and the iron yokes are connected through four screws on a clamping piece. The upper and lower ends of the winding are pressed by insulating plates and fixing bolts. The device can accurately simulate various mechanical faults such as core limb looseness, yoke lamination looseness, inter-yoke looseness and winding looseness at different positions and severity degrees, realizes fault evolution dynamic observation and signal characteristic analysis under different loads, and provides a systematic test basis for subsequent construction of a fault diagnosis model and an active defense strategy.
