Abstract

406,017. Arc rectifiers. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Aug. 12, 1932, No. 22657. Convention date, Sept. 19, 1931. [Class 39 (i).] Back-ignition is prevented by the provision within the arc to each anode of a blocking space which is closed at each end by a group of grids, the grids in each group extending to the boundary surface of the anode sleeve or arm or of the rectifier vessel, and being so arranged that straight lines parallel to the axis of the discharge path cannot pass through them. The grids may be formed of flat, cylindrical, spherical, oblique, curved or bent surfaces in louvre arrangement. A mercury arc rectifier is provided with a blocking space 7, Fig. 1, which is closed at each end by grids 4, 5 connected to a potentiometer 12 to subdivide the potential between the anode and cathode into approximately equal steps. In a modification, a gas-filled valve is provided with a hot cathode 17, Fig. 5, and blocking spaces formed by grids 19-22 which consist of perforated surfaces provided with wires 23. Further arrangements of grids are shown in Figs. 2, 3 and 4. The shortest distance a between adjacent groups of grids and between the anode and the group nearest thereto is less than the depth, preferably less than one fifth of the depth, of the cathode dark space and less than the diameter d of the path of the discharge. The orifices in the outer lying grids are small compared with the distance between adjacent groups, and the width b of the channels in the grid is equal to or less than the distance between adjacent groups. To facilitate ignition, a battery may be used as shown in Fig. 2 to create a comparatively small difference of potential between the grids of a group. The overlap between the members of adjacent grids may be increased at the edges as shown in Fig. 4 to arrest ions which are not moving in a path parallel to that of the discharge. The cross-sectional area of the channels through the grids is equal to about the square of b, and the width b of the channels is less than the distance a. A relationship between a and b is given in the Specification. The grids may be used for controlling the arc.
