Title: Improvements in and relating to rotary converters
IPC: H02P1/16
Filed: 1921-07-18
Abstract: 183,037. Igranic Electric Co., Ltd.. (Cutler-Hammer Manufacturing Co.). July 18, 1921. Systems for conversion, employing rotary converters.-In order to ensure correct polarity on the direct-current side of a rotary converter, the field winding of the converter is temporarily connected to a direct-current source of constant polarity each time the converter is started. In the arrangement shown, the converter is supplied from the three-phase lines L<1>, L<2>, L<3> through a transformer T. On closing a main switch 8. the winding 6<a> of a starting-switch 6 is energized from the secondary of the transformer through a circuit which includes an auxiliary switch 10 connected to the running switch 7. The slip rings 3 of the converter are thereupon connected to low-voltage taps on the secondary of the transformer, and the converter starts as an induction motor, the circuit of the field winding 2 being closed through one arms 12<a>, 13<a> of switches 12, 13 and through a resistance R. When synchronism is attained, a winding 9<a> connected across the direct-current lines L<4>, L<5> operates a switch 9, and closes the circuit of the energizing- winding 7<a> of the running switch 7 at 9<c>, the energizing-circuit of the starting-switch 6 being simultaneously opened at 9<b>. The switch 7 then closes to supply the full voltage of the transformer to the slip-rings 3. At the same time the switch 10 opens to ensure continued interruption of the energizing. circuit of the switch 6, and a switch 11 closes to establish a maintaining-circuit for the winding 7a. Closure of the switch 11 also completes the energizing-circuit of switch 12, which, in responding, disconnects the field winding 2 from the resistance R through the arm 12a and connects it to a battery B through the arms 12<b>, 12<c>, thereby correcting reversal of polarity of the converter if such has occurred during starting. At the same time the winding 14a of a relay 14 is connected across the battery through the arms 12<b>, 12<c>. This relay is provided with an additional winding 14<b> connected across the direct-current lines, and when the current in these lines is of zero frequency and of correct polarity, the windings 14a, 14b act cumulatively to effect response of the relay 14 against the action of a dash-pot 16. This closes the circuit of the energizing-winding 13f of switch 13, which thereupon connects the field winding 2 across the direct-current lines through the arms 13<b>, 13<c>. At the same time the energizing-circuit. of the switch 12 is opened at the arm 13<d>, and the energizing-circuit of a line switch 15 is closed by the arm 13e.
