Description

Известны способы автоматизации рудничных подъемных установок с асинхронным приводом.Known methods of automation miner hoisting plants with asynchronous drive.

Отличительной особенностью предлагаемой системы  вл етс  применение многообмоточных регул торов давлени  с обмотками, включенными в схему сравнени  фактической и заданной скоростей- Эта сист€ма дает возможность управл ть жидкостным реостатом и механическим тормозом по нескольким сигналам управлени  без промежуточных cилитeлeй, что упрощает схему и повышает экономичность установки.A distinctive feature of the proposed system is the use of multiwinding pressure regulators with windings included in the comparison circuit of actual and predetermined speeds. This system makes it possible to control the liquid resistor and mechanical brake using several control signals without intermediate power, which simplifies the design and increases the efficiency installation.

На чертеже изображена предлагаема  принципиальна  схема автоматизации шахтной подъемной установки.The drawing shows the proposed schematic diagram of the automation of mine lifting installation.

Жидкостный реостат / и .механически) тормоз 2 управл ютс  однотипно электропневматическими регул торами 3 ц 4 давлени . Катушки 5, 6 W 7 управлени  регул торов включены в схему сравнени  фактической и заданной скоростей, состо щую из тахогенератора 8 и реостата 9 задани . Регул тор 3 реостата имеет две катушки 5 и 6. Катушка 6 включена на напр жение заданной скорости, чем обеспечиваетс  снижение сопротивлени  в роторе по .мере увеличени  задани  скорости. Катушка 5 корректирует скорость ввода или вывода ножей реостата в зависимости от фактического рассогласовани  скорости, обеспечива  точное соответствие между фа-чтической и необходи.мой величиной момента двигател . Катушка 7 регул тора тормоза включена на рассогласование скоростей, чем обеспечиваетс  требуема  величина тормозного момента.The fluid resistor / and. Mechanically) brake 2 are controlled in the same manner by electropneumatic controllers 3 q 4 pressure. The control coils 5, 6 W 7 are included in the comparison circuit of the actual and set speeds, consisting of the tachogenerator 8 and the rheostat 9 of the task. The regulator 3 of the rheostat has two coils 5 and 6. The coil 6 is turned on for a voltage of a given speed, thereby reducing the resistance in the rotor as the speed increase increases. The coil 5 adjusts the speed of input or output of the rheostat blades depending on the actual speed mismatch, providing an exact match between the actual and the required value of the engine torque. The brake regulator coil 7 is switched on for the velocity mismatch, thus ensuring the required braking torque.

Одновременное нарастание тормозного и двигательного моментов исключено. В зависимости от отклонени  фактического движени  от заданного , система сама настраиваетс  на требуемый режим.The simultaneous increase of the braking and motor moments is excluded. Depending on the deviation of the actual movement from the target, the system itself adjusts to the desired mode.
