постоянный ток
Электрический ток, не изменяющийся во времени.
Примечание — Аналогично определяют постоянные электрическое напряжение, электродвижущую силу, магнитный поток и т. д.
[ ГОСТ Р 52002-2003]Параллельные тексты EN-RU For definition, the electric current called “direct” has a unidirectional trend constant in time.
As a matter of fact, by analyzing the motion of the charges at a point crossed by a direct current, it results that the quantity of charge (Q) flowing through that point (or better, through that cross section) in each instant is always the same.
[ABB]Постоянным током называется электрический ток, значение и направление которого, не изменяются во времени.
Если рассматривать постоянный ток как прохождение элементарных электрических зарядов через определенную точку, то значение заряда (Q), протекающего через эту точку (а вернее через это поперечное сечение проводника) за единицу времени будет постоянным.
[Перевод Интент]Direct current, which was once the main means of distributing electric power, is still widespread today in the electrical plants supplying particular industrial applications.
The advantages in terms of settings, offered by the employ of d.c. motors and by supply through a single line, make direct current supply a good solution for railway and underground systems, trams, lifts and other transport means.
In addition, direct current is used in conversion plants (installations where different types of energy are converted into electrical direct energy, e.g. photovoltaic plants) and, above all, in those emergency applications where an auxiliary energy source is required to supply essential services, such as protection systems, emergency lighting, wards and factories, alarm systems, computer centers, etc..
Accumulators - for example – constitute the most reliable energy source for these services, both directly in direct current as well as by means of uninterruptible power supply units (UPS), when loads are supplied in alternating current.
[ABB]Когда-то электрическая энергия передавалась и распределялась только на постоянном токе. Но и в настоящее время в отдельных отраслях промышленности постоянный ток применяется достаточно широко.
Возможности использования двигателей постоянного тока и передачи электроэнергии по линии с меньшим числом проводников дают неоспоримые преимущества при электроснабжении железных дорог, подземного транспорта, трамваев, лифтов и т. д.
Кроме того, существуют источники постоянного тока, являющиеся преобразователями различных видов энергии непосредственно в электрическую энергию, например, фотоэлектрические станции. Дополнительные источники постоянного тока применяют в аварийных ситуациях для питания систем защиты, аварийного освещения жилых районов и на производстве, систем сигнализации, компьютерных центров и т. д.
Для решения указанных задач наиболее подходящим источником электроэнергии является аккумулятор. Нагрузки постоянного тока получают электропитание непосредственно от аккумулятора. Нагрузки переменного тока – от источника бесперебойного питания (ИБП), частью которого является аккумулятор.
[Перевод Интент]Direct current can be generated:
- by using batteries or accumulators where the current is generated directly through chemical processes;
- by the rectification of alternating current through rectifiers (static conversion);
- by the conversion of mechanical work into electrical energy using dynamos (production through rotating machines).
[ABB]Постоянный ток можно получить следующими способами:
- от аккумуляторов, в которых электрическая энергия образуется за счет происходящих внутри аккумулятора химических реакций;
- выпрямлением переменного тока с помощью выпрямителей (статических преобразователей);
- преобразованием механической энергии в электрическую с помощью генераторов постоянного тока (вращающихся машин).
[Перевод Интент]In the low voltage field, direct current is used for different applications, which, in the following pages, have been divided into four macrofamilies including:
- conversion into other forms of electrical energy (photovoltaic plants, above all where accumulator batteries are used);
- electric traction (tram-lines, underground railways, etc.);
- supply of emergency or auxiliary services;
- particular industrial installations (electrolytic processes, etc.).
[ABB]Можно выделить четыре области применения постоянного тока в низковольтных электроустановках:
- преобразование различных видов энергии в электрическую (фотоэлектрические установки с аккумуляторными батареями);
- энергоснабжение транспорта на электрической тяге (трамваи, метро и т. д.)
- электропитание аварийных или вспомогательных служб;
- специальные промышленные установки (например, с использованием электролитических процессов и т. п.).
