Abstract

PURPOSE:To secure the reduction of both the arc-extinguishing capacitor and the serial reactor down to 1/2 as well as the extreme reduction of the capacity for the charging device, by connecting the other end of a pair of auxiliary SCR's each to both ends of the main SCR. CONSTITUTION:The arc-extinguishing circuit consists of just a set of capacitor C5 charged one-sidedly to the polarity shown in the diagram and serial reactor L6. And then auxiliary SCR3 and 4' plus 3' and 4'' are connected to both the terminals connected in series. In case the current of main SCR1 is broken, the overcurrent is detected by current transformer 14. And the gate signal is applied to SCR3 and 3' through control unit 11, and the current is flowed through the circuits of C5, C6 plus SCR3, 1 and 3' each in order to give the arc-extinguishment to SCR1. After this, C5 is charged to the opposite polarity, and the breaking completes when the electric conduction is over for nonlinear resistance 12. And main SCR2 can be broken with application of the signals of SCR4 and 4'.
