ограничитель перенапряжений нелинейный
ОПН
Аппарат, предназначенный для защиты изоляции электрооборудования от грозовых и коммутационных перенапряжений, представляющий собой последовательно и/или параллельно соединенные металлооксидные варисторы без каких-либо последовательных или параллельных искровых промежутков, заключенные в изоляционный корпус
[ ГОСТ Р 52725-2007]EN
metal-oxide surge arrester without gaps
arrester having non-linear metal-oxide resistors connected in series and/or in parallel without any integrated series or parallel spark gaps
[IEC 60099-4, ed. 2.0 (2004-05)]FR
parafoudre à oxyde métallique sans éclateur
parafoudre à résistances variables à oxyde métallique connectées en série et/ou en parallèle, ne comportant pas d'éclateurs en série ou en parallèle
[IEC 60099-4, ed. 2.0 (2004-05)]В электрических сетях часто возникают импульсные всплески напряжения, вызванные коммутациями электроаппаратов, атмосферными разрядами или иными причинами. Несмотря на кратковременность такого перенапряжения, его может быть достаточно для пробоя изоляции и, как следствие, короткого замыкания, приводящего к разрушительным последствиям.Для того, чтобы устранить вероятность короткого замыкания, можно применять более надежную изоляцию, но это приводит к значительному увеличению стоимости оборудования. В связи с этим в электрических сетях целесообразно применять разрядники.
Ограничитель перенапряжения нелинейный (ОПН) — это элемент защиты без искровых промежутков. Активная часть ОПН состоит из легированного металла, при подаче напряжения он ведет себя как множество последовательно соединенных варисторов. Принцип действия ОПН основан на том, что проводимость варисторов нелинейно зависит от приложенного напряжения. При отсутствии перенапряжений ОПН не пропускает ток, но как только на участке сети возникает перенапряжение, сопротивление ОПН резко снижается, чем и обуславливается эффект защиты от перенапряжения. После окончания действия перенапряжения на выводах ОПН, его сопротивление опять возрастает. Переход из «закрытого» в «открытое» состояние занимает единицы наносекунд (в отличие от разрядников с искровыми промежутками, у которых это время срабатывания может достигать единиц микросекунд). Кроме высокой скорости срабатывания ОПН обладает еще рядом преимуществ. Одним из них является стабильность характеристики варисторов после неоднократного срабатывания вплоть до окончания указанного времени эксплуатации, что, кроме прочего, устраняет необходимость в эксплуатационном обслуживании
На электрических принципиальных схемах в России разрядники обозначаются согласно ГОСТ 2.727—68.

Surge arresters
To limit the occurrence of over voltages, an over voltage arrester is available upon request.
The encapsulated surge arrester is designed on the basis of metallic oxide conductive resistors.
These blow out if there is an overload, and the system protection turns off the faulty electrical circuit in a controlled manner.
The surge arrester is in single-pole design.
It has its own enclosure sealed by a sealed bushing.
Connections for equipment to monitor the arrester.
[Siemens]Ограничитель перенапряжений
По запросу КРУЭ оснащается ограничителями перенапряжений.
Ограничитель перенапряжений выполнен на базе металлооксидных варисторов и помещен в оболочку.
При возникновении перенапряжения варисторы переходят в проводящее состояние, в результате чего система защиты отключает неисправную электрическую цепь.
Ограничитель перенапряжений выполнен в виде однополюсного модуля.
Ограничитель имеет собственную оболочку, герметично закрытую проходным изолятором.
Ограничитель перенапряжений имеет выводы для подключения приборов контроля его состояния.
[Перевод Интент]The GIS lay out in option of zinc oxide lightning arrester under metal enclosure insulated with gas SF6.
The zinc oxide lightning arrester earths currents of considerable amplitude injected by accidental phenomena: lightning and operating overvoltages.
The non-linear resistance of the zinc oxide maintains a residual voltage lower than the GIS insulation voltage during the flow of high currents.
An impulse counter records the number of times high current passes through the conductor and the maximum amplitude attained.
[Siemens]В КРУЭ может быть установлен ограничитель перенапряжений, выполненный на основе оксидноцинковых варисторов, размещенных в металлической оболочке, заполненной элегазом.
Оксидноцинковый ограничитель перенапряжений отводит на землю значительные по амплитуде токи, которые могут появиться в результате атмосферных и коммутационных перенапряжений.
При протекании значительного тока значение поддерживаемого нелинейным оксидноцинковым варистором остающегося напряжения ниже напряжения изоляции КРУЭ.
Отдельный счетчик подсчитывает каждый проход тока через ограничитель и его амплитуду.
[Перевод Интент]Transport and storage
Lightning arresters are filled with SF6 or nitrogen gas under pressure in the factory.
They are also fitted with a moisture filter.
Maintain the lightning arrester in a vertical position during transport and storage.
[Siemens]Транспортирование и хранение
Ограничители перенапряжений заправлены на заводе-изготовителе элегазом или азотом под давлением.
Ограничители оснащены фильтром-осушителем.
При транспортировании и хранении ограничители перенапряжений должны находиться в вертикальном положении.
