Abstract

Система, содержащая резистивные плечи цепи, соединенные с (a) преобразователем, который преобразует электрический ток для электродвигателя механизированной системы, и с (b) источником электрического тока для питания электродвигателя, и размещенные между ними, при этом каждое плечо цепи содержит тормозное сопротивление, соединенное с преобразователем, контактор, соединенный с тормозным сопротивлением так, что тормозное сопротивление расположено между преобразователем и контактором, и полупроводниковый ключ, соединенный с контактором так, что контактор расположен между полупроводниковым ключом и тормозным сопротивлением, и при этом в режиме рекуперативного торможения механизированной системы рекуперируемую из электродвигателя энергию передают на тормозное сопротивление и рассеивают в виде тепла.A system comprising resistive circuit legs connected to (a) a converter that converts electric current for the electric motor of the mechanized system, and (b) an electric current source for powering the electric motor, and placed between them, and each leg of the circuit contains a braking resistance connected with the converter, a contactor connected to the brake resistor so that the brake resistor is located between the converter and the contactor, and a semiconductor switch connected to the contactor so that the contactor is located between the semiconductor switch and the brake resistor, and at the same time, in the regenerative braking mode of the motorized system, regenerative from In the electric motor, the energy is transferred to the braking resistor and dissipated as heat.
