Transformer low voltage side winding characteristic fault simulation device and simulation method thereof

Abstract

The invention discloses a transformer low voltage side winding characteristic fault simulation device and simulation method thereof. The device comprises an a phase winding, a b phase winding, a c phase winding and a neutral line n. Each phase of winding comprises a resistor and three parallel connected branch windings which are connected in series with the resistor. The two ends of the resistor are connected with a resistor short circuit switch. Each branch winding comprises a first strand of winding and a second strand of winding which are connected in series in turn. The start end and the tail end of the first strand of winding are connected with a winding short circuit switch. An open circuit switch is connected between the first strand of winding and the second strand of winding. The first branch line after merging of the tail ends of all the branch windings is connected with a double-gear switch. One end of the two outgoing line ends of the double-gear switch is connected with the start end of the branch winding of the adjacent winding, and the other end is connected with the neutral line n. Low voltage side winding characteristic fault simulation can be realized by operating all the switches so that the structure is simple, the cost is low, the space occupation is small, the simulation effect is better, equipment operation with fault can be avoided, the equipment risk can be reduced and the training effect can be enhanced.
