Repulsive force mechanism switching-on and switching-off buffer device suitable for reactive compensation equipment switching

The invention relates to a repulsive force mechanism for reactive power compensation equipment switching. The repulsive force mechanism comprises a repulsive force mechanism and a buffer device. The buffer device comprises a fixed-value resistor R1 and an adjustable resistor R2 which are connected in parallel, and the fixed-value resistor R1 and the adjustable resistor R2 are both connected with the coil panel in series. The buffer device further comprises a switch used for controlling on-off of branches where the fixed-value resistor R1 and the adjustable resistor R2 are located, and the branches where the fixed-value resistor R1 and the adjustable resistor R2 are located cannot be in an on state at the same time. A buffer device is additionally arranged in a power supply circuit of the coil panel, a repulsive magnetic field between the repulsive force disc and the coil panel is adjusted to drive the repulsive force disc to act, and opening and closing actions of the vacuum arc-extinguishing chamber are achi
