Description

(54) ЭЛЕКТРОГИДРАВЛИЧЕСКИЙ РЕГУЛЯТОР МОЩНОСТИ(54) ELECTRO-HYDRAULIC POWER CONTROLLER

ДУГОВЫХ ЭЛЕКТРОПЕЧЕЙArc furnaces

Статическое давление в полости цилив ра 1 несколько выше, чем давление в аккумул торе , поэтому обратные клапаны 6 и 8 закрыты.The static pressure in the cylinder cavity 1 is slightly higher than the pressure in the accumulator, therefore, the check valves 6 and 8 are closed.

При преобладании сигнала, например, по току золотник 10 электроги;фавлического :преобразовател  2 перемещаетс  вправо и I пропорционально сигналу рассогласовани  i перекрывает щель полости преобразовател . Количество поступающей на вход насоса 5 рабочей жидкости уменьшаетс , в то врем  как насос 3 обеспечивает прежнюю номи- нальную производительность. Гидроцилин/ф 1 перемешаетс  вверх до достижени  зада1ь ного электрического режима. Таким обра- зом, отрабатываютс  возмущени  в номинальном режиме работы регул тора.When the signal prevails, for example, over the current, the spool 10 of the electrogauge is favored: converter 2 moves to the right and I, in proportion to the error signal i, overlaps the slot of the converter cavity. The amount of working fluid entering the pump 5 is reduced, while pump 3 provides the same nominal capacity. Hydrocyline / f 1 is stirred upward to achieve a predetermined electric mode. Thus, the perturbations in the nominal mode of the regulator are fulfilled.

При возникновении короткого замыкани , когда сигнал рассогласовани   о току достигает максимальной величины, золотник Ю перекрывает щель полости преобразовател  2, и сигнал, например, от реле максимального тока поступает на электродвигатель 11 насоса 7 форсированного переме .щени  элшстрода. Насос 7 качает жидкость jB попорть цилиндра перемещени  электрода. Суммарна  производительность насоса 3 и насоса 7 обеспечивают быстрый подъем I электрода.When a short circuit occurs, when the current mismatch signal reaches its maximum value, the spool Yu closes the gap of the converter 2, and the signal, for example, from the overcurrent relay, is fed to the electric motor 11 of the pump 7 of the forced switching of the electr. Pump 7 pumps fluid jB through the cylinder moving the electrode. The total performance of the pump 3 and pump 7 provide a quick rise of the I electrode.
