Full-insulation electric electronic recitifier bridge arm

The utility model relates to a full-insulation electric power electronic rectifier bridge arm. In the prior art, in the structure of the insulation electric power electronic rectifier bridge arm, an insulation jacket is arranged on a fastening bolt. However, as the wall of the insulation jacket is relatively thin, after a few years, a generatrix is broken down because of insulation aging, moisture and partial discharge, which causes fateful short circuit accident and serious equipment damage. The bolt and the insulation jacket of the utility model are in all-in-one structure. The bolt and the insulation jacket, which are in all-in-one structure use high strength polyester materials. So the utility model is simple in structure and durable. The industrial frequency withstand voltage is over twenty thousand voltage, and the insulation breakdown problem is avoided.
