The control circuit of the conveyor drive according to the MU - G - D system with dynamic current limiting.
Abstract
In powerful blast furnaces, conveyors equipped with DC electric drive controlled by MU-G-D system with dynamic current limiting by incorporating a semiconductor amplifier into the output diagonal of the differentiating bridge are used to feed the sinter from the racks to the weighing bins. On an analog computer, the gain of the amplifier was determined, providing the specified transient. The conclusion is made about the expediency of dynamic current limiting with an amplifier at the output of the differentiating bridge for all electric drives for which the stop mode is not an operating mode.
