Предлагаетс  устройство дл  ограничени  тока короткого замьжани  в линии при помощи двухобмоточного дроссел  (реактора), сопротивление которого резко увеличиваетс  при коротком замыкании.A device is proposed for limiting a short-circuit current in a line by means of a double-wound throttle (reactor), whose resistance increases dramatically during a short circuit.

Принцип работы устройства показан на прилагаемой схеме.The principle of operation of the device is shown in the attached diagram.

Основна  обмотка дроссел  Д, включенна  непосредственно в линию , шунтирована емкостью С через разр дник Р.The main winding of the throttles D, is connected directly to the line, shunted with a capacitance C through the discharge gap R.

К зажимам разр дника подключена втора  обмотка дроссел  (реактора) последовательно с дополнительной индуктивностью L, рассчитанной на резонанс напр жений с указанной емкостью .A second winding of the drossel (reactor) is connected to the discharge terminals in series with an additional inductance L, designed for resonance of voltages with the indicated capacitance.

Ток в обмотках дроссел , как видно из схемы, протекает в разных направлени х и, таким образом, при нормальном режиме (когда разр дник не пробит) реактор размагничен и его реактивное сопротивление близко к нулю.The current in the windings of the throttles, as can be seen from the scheme, flows in different directions and, thus, under normal conditions (when the discharge is not broken), the reactor is demagnetized and its reactance is close to zero.

При коротком замыкании в линии разр дник пробиваетс , основна  обмотка замыкаетс  на емкость, а до12In the case of a short circuit in the line, the spark gap breaks through, the main winding closes on the capacitance, and up to 12

Предмет изобретени Subject invention

Устройство дл  ограничени  тока короткого замыкани  в линии при помощи двухобмоточного реактора, автоматически увеличивающего свое сопротивление при коротком замыкании , отличающеес  тем, что основна  обмотка шунтирована емкостью через разр дник, параллельно которому включена дополнительна  обмотка последовательно с индуктивностью , рассчитанной на резонанс напр жений с указанной емкостью , с той целью, чтобы при нормальной нагрузке дополнительна  обмотка полностью размагничивала реактор, а при коротком замыкании происходили пробои разр дника, замыкание основной обмотки на емкость , а дополнительной на индуктивность , и происходило намагничивание реактора.A device for limiting a short-circuit current in a line by means of a double-winding reactor, which automatically increases its resistance during a short circuit, characterized in that the main winding is shunted by a capacitor through a discharge circuit in parallel with which an additional winding is connected in series with the inductance calculated for voltage resonance with the indicated capacitance , with the intention that during normal load the additional winding completely demagnetizes the reactor, and during a short circuit, the the discharge wallpaper, the main winding shorting to the capacitor, and an additional one to the inductance, and the magnetization of the reactor occurred.
