Description

Дл  защиты линий электропере .дачи примен ют реле сопротивлени , воспринимающий орган которых выполнен по схеме моста, содержащего в разных плечах два элемента сопротивлени , измен ющих свою величину в зависимости от тока и напр жени  защищаемой линпи .To protect power lines, impedance relays are used, the sensing organ of which is made according to the bridge circuit, which contains two impedance elements in different arms, which vary in magnitude depending on the current and voltage of the protected linpie.

Предлагаемое реле более надежно в работе по сравнению с известными реле подобного рода и дает меньщие погрешности измерени .The proposed relay is more reliable in operation as compared to the known relays of this kind and gives smaller measurement errors.

Это достигаетс  тем, что элементы сопротивлени  выполнены из материалов , величина электрического сопротивлени  которых зависит от индукпии магнитного пол , создаваемого катушками, питаемыми током и напр жением защищаемой линии.This is achieved by the fact that the resistance elements are made of materials whose electrical resistance depends on the induction of the magnetic field created by the coils fed by the current and the voltage of the protected line.

На чертеже приведена принципиальна  схема предлагаемого реле. Реле содержит два полупроводниковых сопротивлени  1 и 2, включенные в мостовую схему, у которой два других плеча состо т из линейных сопротивлений 3. К одной из .диагоналей моста подключен источник питани  а к другой-пол ризованное или магнитоэлектрическое реле 5.The drawing shows a schematic diagram of the proposed relay. The relay contains two semiconductor resistors 1 and 2, included in a bridge circuit, in which the other two arms consist of linear resistances 3. A power supply is connected to one of the bridge diagonals and the other is polarized or magnetoelectric relay 5.

Полупроводниковые сопротивлени  моста помещены в пол , создаваемые катущками электромагнитных систем 6 и 7, питаемых током и напр жением защищаемой линии.The semiconductor resistances of the bridge are placed in the floor generated by the coils of the electromagnetic systems 6 and 7, fed by the current and voltage of the protected line.

При одинаковых ампер-витках в катушках электромагнитных систем 6 и 7 сопротивлени  1   2 будут равны , и ток в цепи пол ризованного реле 5 будет равен нулю.With the same ampere turns in the coils of the electromagnetic systems 6 and 7, the resistances 1 2 will be equal, and the current in the circuit of the polarized relay 5 will be zero.

При нарушении равенства указанных ампер-витков сопротивлени  / и 2 измен ютс  неодинаково, и через реле 5 протекает ток, вызывающий его срабатывание.If the equality of the indicated ampere-turns of the resistances I and 2 is violated differently, a current flows through the relay 5 causing it to trip.

Вторична  обмотка трансформатора 8, через который подаетс  питание на катушки электромагнитных систем 6 и 7, имеет ответвлени  дл  регулировки уставки реле.The secondary winding of the transformer 8, through which the power is supplied to the coils of the electromagnetic systems 6 and 7, has branches for adjusting the relay setpoint.
