Description

Предметом п,сбретек 1Я  вл етс  устройство дл  диференциальиой защиты трансформаторов с применением реле с тормозными катушками .The subject of the first battery is a device for differential protection of transformers using relays with brake coils.

Согласно изобретению, с целью блскировки зашиты от бросков тока намагнич1изани , предлагаетс  :тополнительнук ) тормозную кату.ику реле ннтать от обмотки, наложенной иа вспомогательный магнитопрсзод , установленный на глазном магнитопрОБОде трансформатора.According to the invention, for the purpose of blocking protection from inrush currents, it is proposed: an additional brake brake cat relay relay from a winding superimposed on an auxiliary magnetic field mounted on the transformer magnetic field.

На чертеже приведена прнчцппиальна  электрическа  схема пред/гагаемого устройства.The drawing shows an electrical circuit diagram of a pre / gag device.

На магнитопроводе .VI лащ1 щаемого трансформатора устанавливаетс  дополнительный магнитопровод Л1,, на который наматываетс  вспомогательна  обмотка 6.An additional magnetic circuit L1 is mounted on the magnetic conductor .VI of the transformer's trough transformer, onto which the auxiliary winding 6 is wound.

Защита трансфор.матора осуществл етс  обычным балансным эпектромагннтньпг реле с рабочими катущками /. 2 и . и тормозными катушками 4 и 5. Последние питаотс  от вспомогательной обмотки (j трансформатора (обмотка 5 не об зательна ).The protection of the transformer is carried out by a conventional balanced relay with working coils. 2 and. and brake coils 4 and 5. The last pithots from the auxiliary winding (j transformer (winding 5 is not necessary).

При броске намагничивающего тока ампер-витки тормозной обмот| и 4 тормоз т подвижную систему реле и не дают efi замкнуть контакты . Одновременно обмотка 5 комненсирует действие рабочей обмотки 3. Благодар  этому защита .-ie реагирует на броски намагничиваюндего тока.When throwing a magnetizing current amp-turns brake coil | and 4 brake t mobile relay system and do not allow efi to close the contacts. At the same time, winding 5 compensates for the action of the working winding 3. Thanks to this, the protection.-Ie reacts to inrush current magnetizing.

При повреждении в 3r3i unuae.ioii зоне намагничивающий ток имеет незначнтельиую вели-1ину (во вс ком случае, не превос.кодп своего нормального значени ), вследствие чего ампер-витки об ото1ч -# и 5 не могут противодействовать амперг иткам рабочей обмотки S. через которую в этом случае проходит бильщой ток. При этом з.-шгита работает на отк.почеиие трансформатора .In case of damage in the 3r3i unuae.ioii zone, the magnetizing current has an insignificant magnitude (in all cases, it does not exceed its normal value), as a result of which the amp-turns about ot1ch - # and 5 cannot counteract the ampers of the operating winding S. through which in this case the current flows. In this case, z.-shgita works on the opening of the transformer.
