Abstract
The invention discloses a locomotive rectifier. Positioning rings are arranged at the two ends of a pipe core and located in a ceramic ring so that the pipe core can be protected. The pipe core is covered with a layer of polyester modified silicon paint, under high voltage, the charge transporting stability of the pipe core can be improved, the polyester modified silicon paint is covered with a layer of silicon rubber, excellent insulating performance is achieved, the crushing resistance of the pipe core can be improved, edge breakage or damage is avoided, and a cooler is a copper cooler and is small in unit size heat resistance, high in efficiency, attractive in appearance and stable in assembly repeated press fitting performance. The locomotive rectifier has the advantages of being low in cost, small in structure, good in cooling performance and long in service life and has wide market prospects.
