Abstract
424,954. Converting. AKT.-GES. BROWN, BOVERI, & CIE, Baden, Switzerland. May 31, 1933, No. 15708. Void [Abridged as open to inspection under Sect. 91 of the Acts, Dec. 4, 1933]. [Class 38 (ii)] In a mercury arc rectifier for supplying a flame-arc furnace a falling voltage characteristic is obtained by controlling the phase of the grid potential in such a way that the moment of ignition is progressively retarded with increasing load. In the form shown in Fig. 1, the grid e of a 6-phase rectifier g are supplied from a transformer s, the primary of which is supplied from a further transformer h, the leads including the secondary windings of a current transformer p in the A.C. supply circuit n to the rectifier. In this way the voltage applied to the grid is the combination of a component of constant voltage and a component the voltage of which is dependent on the load current and 90‹ out of phase therewith. Fig. 2 is a vector diagram showing the current and voltage relationships. EA is the anode voltage, eg is the component of grid voltage due to the transformer h, ez is the component of voltage due to the current transformer p. The locus of the end point of the vector eg representing the grid voltage is a circle on O, A as chord and having a peripheral angle of 30‹. The angle EA, O, A is the phase angle between the anode and grid voltages at zero load. The shape of the characteristic can be modified by varying this angle.
