The utility model discloses a transformer high-speed signal coupling and transmitting device, comprising a rotating shaft, a rotor which, with the rotating shaft as the center, is arranged on the rotating shaft, a stator which, with the rotating shaft as the center, is arranged in parallel with the rotor, a first exciting coil and a first detecting coil on the rotor, a second exciting coil and a second detecting coil on the stator and at least one point probe on the rotating shaft. The point probe is connected with the first exciting coil and the first detecting coil on the rotor, and an eddy current testing instrument is connected with the second exciting coil and the second detecting coil on the stator. The transformer high-speed signal coupling and transmitting device has the beneficial effects that due to the adoption of transformer-type coupling, signals are transmitted with low loss and low distortion, high-frequency exciting signals can be transmitted to the exciting coil in an undistorted manner, and
