Description

Современные однопериодные дистанционные и высокочастотные защиты требуют дл  своего выполнени  сверхбыстродействующих реле сонротивлени , врем  срабатывани  и возврата которых не превыщапо бы 0,005-0,008 сек.Modern single-period remote and high-frequency protections require a high-resistance relay to operate, the response and return times of which do not exceed 0.005-0.008 sec.

Предлагаемое реле сопротивлени , в котором исполнительный орган подключен к цеп м трансформаторов напр жени  и тока через выпр мители , способствует решению этой задачи. Уменьшение времени срабатывани  и возврата такого реле достигаетс  путем включени  указанных трансформаторов в трехфазные системы, соединенные по схеме полной звезды, и включени  выпр мителей по трехфазной двухполупериодной схеме.The proposed resistance relay, in which the actuator is connected to the circuits of voltage and current transformers through rectifiers, contributes to this task. A reduction in the response time and the return time of such a relay is achieved by including these transformers in three-phase systems connected according to a full-star circuit, and switching on rectifiers according to a three-phase full-wave circuit.

На чертеже, изображающем схему предлагаемого реле сопротивлени , изображены первичные обмотки / трансформаторов тока, включенные на фазные токи; вторичные обмотки /; трансформаторынапр жени  2, включенные на фазные напр жени ; сопротивлени  3; выпр мители 4 и конденсатор 5.The drawing depicting the circuit of the proposed resistance relay shows primary windings / current transformers connected to phase currents; secondary windings /; transformer voltage 2 connected to phase voltages; resistance 3; rectifier 4 and capacitor 5.

В каждой фазе левого плеча схемы протекает ток, пропорциональный напр жению V - K.J, в каждой фазе правого плеча - ток, пропорциональный току /Сз/.In each phase of the left arm of the circuit, a current is proportional to the voltage V - K.J, in each phase of the right arm - a current proportional to the current / C3 /.

Таким образом, к выходному устройству реле подаетс  ток пропорциональный /,(1/ - /Ci/) -(/(г/).Thus, a current proportional to /, (1 / - / Ci /) - (/ (g /) is supplied to the output device of the relay.

Это выражение представл ет собой формулу реле сопротивлени .This expression is a resistance relay formula.

Малое врем  срабатывани  и возврата этого реле обеспечиваетс  тем, что он выполнено по трехфазной сравнивающей схеме с трехфазным двухполупериодным выпр млением и потому практически не требует никаких расщепл ющих или сглаживающих устройств. Схема реле построена так, что имеетс  возможность получени  направленного реле сопротивлени , реле полного сопротивлени , а также промежуточных дистанционных реле со смещенной характеристикой.The short response time and the return time of this relay is ensured by the fact that it is made according to a three-phase comparison circuit with a three-phase full-wave rectification and therefore requires almost no splitting or smoothing devices. The relay circuit is designed in such a way that it is possible to obtain a directional impedance relay, an impedance relay, as well as intermediate remote relays with an offset characteristic.
