FIELD: electrical engineering. SUBSTANCE: invention is meant for increased manufacturability and diminished production cost of vacuum arc chute. Vacuum arc chute has vacuumed body composed of cylindrical insulator which butts are closed by metal flanges with mobile and immobile rods. One of rods has communicating holes tightly filled with solder. One or several holes brought out over periphery of rod into internal space of vacuumed body are connected on one level at angle α<arccos2d1/D-d with blind hole passing along rod. EFFECT: increased manufacturability and diminished production cost of vacuum arc chute. 2 dwg |
