The utility model relates to the technical field of high-voltage direct-current generators and high-voltage silicon rectifiers, in particular to a rapid polarity-changing large-current partial-discharge-free silicon rectifier tube, which comprises an insulating shell, silicon discs uniformly distributed in the insulating shell, and voltage-sharing caps arranged at two ends of the insulating shell and used for sharing voltage of non-uniform electric fields at two ends of a silicon rectifier. The axis of the insulating shell is provided with a transmission rod capable of quickly changing polarity, and a hydraulic oil cylinder for driving the transmission rod to reciprocate is arranged in the voltage-sharing cap at one end. The silicon rectifier has the advantages that the silicon direct-current units are all sealed in the insulating shell body, the two ends of the silicon direct-current units adopt the aluminum voltage-sharing caps, the problem of uneven external electric field is effectively solved, the contact adopts the copper block and spring steel ball structure, the through-current problem and the problem of unstable polarity change are solved, and the silicon rectifier is more stable.
