Claims (8)

1. Выключатель высокого и среднего напряжения, в котором возникающий при выключении электрический дуговой разряд смещается под действием магнитного поля в гасительной камере, содержащей газ-диэлектрик, содержащий внешний цилиндрический электрод (6) и центральный электрод (9), расположенный по оси (L) внешнего электрода, отличающийся тем, что центральный электрод (9) проходит через внешний электрод (6).1. High and medium voltage switch, in which an electric arc discharge arising upon switching off is displaced by a magnetic field in a quenching chamber containing a dielectric gas containing an external cylindrical electrode (6) and a central electrode (9) located along the axis (L) an external electrode, characterized in that the central electrode (9) passes through the external electrode (6). 2. Выключатель по п.1, отличающийся тем, что концы (9А, 9В) центрального электрода (9) имеют закругленную форму. 2. The switch according to claim 1, characterized in that the ends (9A, 9B) of the central electrode (9) are rounded. 3. Выключатель по п.2, отличающийся тем, что концы центрального электрода (9) имеют форму полусфер. 3. The switch according to claim 2, characterized in that the ends of the central electrode (9) are in the form of hemispheres. 4. Выключатель по п.2, отличающийся тем, что закругленные поверхности представляют собой половины эллипсоида. 4. The switch according to claim 2, characterized in that the rounded surfaces are half ellipsoid. 5. Выключатель по любому из предшествующих пунктов, отличающийся тем, что два электрода (6,9) крепятся с помощью изолирующей детали (10). 5. The switch according to any one of the preceding paragraphs, characterized in that the two electrodes (6.9) are attached using an insulating part (10). 6. Выключатель по любому из предшествующих пунктов, отличающийся тем, что внешний или центральный электрод или оба электрода (6,9) покрыты изоляцией (11,12) из пластмассы или из огнеупорной керамики для предотвращения перемещения электрического дугового разряда за пределы гасящей камеры. 6. A switch according to any one of the preceding paragraphs, characterized in that the outer or central electrode or both electrodes (6.9) are coated with insulation (11.12) made of plastic or of refractory ceramic to prevent the movement of the electric arc discharge outside the quenching chamber. 7. Выключатель по любому из предшествующих пунктов, отличающийся тем, что центральный электрод (9) закреплен на изогнутом проводнике (8') для перемещения по углу подвижного контакта (2) к зажиму (13) заземления. 7. A switch according to any one of the preceding paragraphs, characterized in that the central electrode (9) is mounted on a curved conductor (8 ') to move along the corner of the movable contact (2) to the ground terminal (13). 8. Выключатель по п.7, в котором центральный электрод (9) связан с зажимом заземления (13) через подвижной контакт (2). 8. The switch according to claim 7, in which the central electrode (9) is connected to the ground terminal (13) through a movable contact (2).
