System for automatic control of dynamic braking of independent transport facility

摘要

A system for automatic control of dynamic braking of an independent transport facility comprises an exciting-current regulator of traction motors provided with rotational-speed transducers whose outputs are connected to the input of a traction-motor reactive e.m.f. limiter, and a voltage transducer whose output is coupled to the first input of a traction-motor exciting-current and brake-horse-power limiter formed with three interconnected rectifying bridges, the outputs of the two bridges being connected in accord and coupled to the output of the third bridge and to one input of a comparison unit, while the inputs thereof are connected to an exciting-current transducer and to a braking intensity setter, the second input of the comparison unit being connected through a diode to the traction-motor reactive e.m.f. limiter.
