The invention relates to a switching experiment device for an on-load tap changer. The switching experiment device comprises a power supply, a synchronous driving mechanism, an accompanied on-load tapchanger, an electric reactor and a capacitor, wherein a tested on-load tap changer and the accompanied on-load tap changer are connected with the power supply and are respectively independently connected to one of the electric reactor and the capacitor, and the electric reactor and the capacitor are connected with the power supply; and the synchronous driving mechanism is connected with the accompanied on-load tap changer and the tested on-load tap changer and is used for driving the accompanied on-load tap changer and the tested on-load tap changer to be synchronously switched. According tothe switching experiment device for the on-load tap changer, the switching action of the tested on-load tap changer can be realized under a load condition, the actual operation state is effectively simulated, and the switching experiment equivalence of each performance of the on-load tap changer can be improved.
