The utility model relates to a tail protection device for a capacitor bushing. The tail protection device comprises a fixed frame, a connecting rod hinged with the fixed frame and a supporting plate arranged on the connecting rod, wherein the front end and the rear end of the fixed frame are respectively provided with a front trundle and a rear trundle. During the use of the tail protection device provided by the utility model, the whole tail protection device is fixed at the tail of the bushing through the connecting rod, and the supporting plate arranged on the connecting rod can support the bushing; as the connecting rod is hinged with the fixed frame, an angle between the connecting rod and the fixed frame is changed accordingly when the bushing is started to be hung; meanwhile, the two trundles are arranged front and back, so that the device can be prevented from being damaged or quickly sliding out; the trundles arranged on the fixed frame are always in contact with the ground and slide forwards along the hanging direction, so that the tail of the bushing is in no contact with the ground, and the bushing can be protected; the labor is reduced, and the injury to workers is avoided.
