CONTROL DEVICE FOR OPERATED REVERSIBLE VOLTAGE TRANSDUCER AT ELECTRIC POWER INSTALLATION WITH AC AND DC SOURCES

摘要

FIELD: electricity.;SUBSTANCE: being comprised of three-phase voltage generator, accumulator battery pack, reversible voltage transducer with current and voltage sensors, transducer control unit and transducer operational mode setting unit the device is equipped additionally with two comparators, two one-cycle multivibrators, three inhibit circuits, 2AND element, OR-NOT element and three transistor keys with LEDs indicating status of the reversible voltage transducer. Introduction of additional elements allows implementing simple and reliable method to control operation of the reversible voltage transducer. In order to design the device wide-spread analogue and digital integrated circuits are used, and the above ICs are featured by low costs, weight and dimensions.;EFFECT: reliability of the device attained by its completion with operation control circuits for the reversible transducer, which allow timely fault detection and elimination.;1 dwg
