Description

Известны устройства дл  подмагинчивани  трехфазным переменным током обмоток коммутирующих дросселей контактиого преобразовател  с фазорегул т ором в цепи подмагничивани  дросселей, служащим дл  изменени  угла регулировани .Devices are known for biasing three-phase alternating current windings of commutating chokes of a contact converter with a phase regulator in a bias circuit of chokes, serving to change the angle of regulation.

В подобных преобразовател х при регулировании угла перекрыти  контактов в соответствии с изменением фазы тока подмагничивани  не удаетс  обеспечить безыскровую работу контактного аппарата и получить оптимальный режим подмагничивани .In such converters, when adjusting the contact overlap angle in accordance with the change in the phase of the bias current, it is not possible to ensure sparkless operation of the contact device and to obtain an optimal bias mode.

В описываемом изобретении эти недостатки устранены путем регулировани  угла перекрыти  -контактов при помощи вспомогательного электродвигател , служащего дл  одновременного поворота ротора фазорегул тора в цепи подмагничивающего тока дросселей и статора приводного двигател  контактного аппарата.In the described invention, these disadvantages are eliminated by adjusting the angle of overlap of the -contacts using an auxiliary electric motor, which serves to simultaneously rotate the phase regulator rotor in the bias current circuit of the chokes and the stator of the drive motor of the contact apparatus.

Схема описываемого устройства показана на чертеже.The scheme of the described device is shown in the drawing.

Подмагничивание дросселей / контактного преобразовател  с переменной фазой тока подмагничивани  производ т от вторичной обмотки фазорегул тора 2. Первична  обмотка фазорегул тора 2 подключена к сети трехфазпого переменного тока, питаюп;его контактный преобразователь .The bias of the chokes / contact transducer with a variable phase bias current is produced from the secondary winding of the phase regulator 2. The primary winding of the phase regulator 2 is connected to the three-phase alternating current network, powered by its contact converter.

Электродвигатель 3 служит дл  изменени  угла перекрыти  контактов . Вал двигател  св зан мехХанически или электрически с ротором и статором приводного двигател  4 контактного аппарата. В этом случае регулировочный электродвигатель, производ щий изменение угла регулировани , одновременно будет поворачивать ротор фазорегул тора подмагничивани  так, что изменение фазы тока подмагничивани  будет равно изменению угла регулировани .The motor 3 serves to change the contact angle. The motor shaft is connected mechanically or electrically with the rotor and stator of the driving motor 4 of the contact apparatus. In this case, the adjustment motor making the change in the angle of adjustment will simultaneously rotate the bias magnet control rotor so that the change in the phase of the bias current will be equal to the change in the angle of control.

При изменении угла регулировани  от О до 180° крива  тока подмагничивани  сдвигаетс  одновременно со сдвигом ступени тока относительно напр жени  переменного тока, и при любом угле регулировани  обеспечиваетс  отсутствие искрени  контактов, а также оптимальныйWhen the angle of regulation is changed from 0 to 180 °, the bias current curve shifts simultaneously with the current level shift relative to the AC voltage, and at any angle of regulation, there is no contact sparking, as well as optimum
