УСТРОЙСТВО дл  ЗАЩИТЫ ОБМОТКИ РОТОРА СИНХРОННОГО ГЕНЕРАТОРА ОТ ЗАМЫКАНИЯ НА ЗЕМЛЮDEVICE FOR PROTECTION OF WINDING OF ROTOR OF SYNCHRONOUS GENERATOR FROM GROUNDING TO EARTH

За влено 1 марта 1941 г. за № 42090 в Народць Комиссариат электросинций ССС:РIt was registered on March 1, 1941 for No. 42090 in Narodts, Commissariat of Electroinfections CCC: Р

В Предлагаемом устройстве дл  защиты обмотки ротора синхронного генератора от замыкани  на землю параллельно зап;ищаемой обмотке приключаетс  нотенциометр, между движком которого и землей включаетс  реле. С целью исключени  вли ни  на действие этого реле переменной составл ющей тока замыкани  на землю последовательно с реле включаетс  дополнительный трансформатор, питаюН1ИЙ всномогательную размагничивающую обмотку реле.In the proposed device for protection of the rotor winding of a synchronous generator from a ground fault parallel to the station, a notentiometer takes place in the winding under search, between which the engine and the earth turn on a relay. In order to eliminate the effect of this relay on the variable component of the earth fault current, an additional transformer is switched on in series with the relay, supplying an all-coherent demagnetizing winding of the relay.

На чертеже изображена электрическа  схема преллагаемого устройства .The drawing shows the electrical circuit of the proposed device.

Между движком нотепциометра / и землей включены последовательно соединенные первична  обмотка дополнительного трансформатора 2 и основна  обмотка реле о. Вторична  обмотка трансформатора 2 пптает вспомогательную размагничивающую обмотку реле 3.Between the engine of the nothepciometer / and the earth are connected in series the primary winding of the additional transformer 2 and the main winding of the relay o. The secondary winding of the transformer 2 ppht auxiliary demagnetizing winding of the relay 3.

Переменна  составл юща  тока замыкани  на землю 1шводнт во вторичной обмотке трансформатора 2 э.д.с., котора  замыкаетс  на вспомогательную обмотку реле 3.The alternating component of the ground wiring current is 1W in the secondary winding of the transformer 2 electromotive force, which is closed to the auxiliary winding of the relay 3.

Так как токи, обусловленные указанной переменной составл юол ,ей и протекающие по основной и вспомогательной обмоткам реле 3. равны по величине и противоположны по фазе, то действие их на  корь реле исключено.Since the currents caused by the specified variable are yol, and the relays 3. flowing through the main and auxiliary windings are equal in magnitude and opposite in phase, their action on the relay is ruled out.

Опыт показывает, что нет необходимости добиватьс  малых угловых онжбок трансформатора.Experience shows that there is no need to achieve small angular onshoot transformers.

Предмет изобретени Subject invention

Устройство дл  защиты обмотки ротора сиихрониого генератора от замыкаии  на землю при помощи реле, включенного между землей и движком иотенцио.метра, ириключеиного параллельно запипцаемой обмотке, о тл и ч а юн;е е с   тем, что дл  исключени  вли ни  на де1 Ствие реле перемен.иой составл ющей тока замыкани  на землю, носледовательно с реле включен дополнительный трансформатор, нит ющий вспомогательную размагничивающую обмотку реле.The device for protection of the rotor winding of the synchronous generator against a ground fault using a relay connected between the earth and the engine of the potentiometer meter and parallel to the lockable winding is parallel to the winding of the relay; An alternating component of the earth-fault current, along with the relay, is an additional transformer, which feeds the auxiliary demagnetizing winding of the relay.
