4 direct current
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.).

Direct-on-line starting
Direct-on-line starting, which is often abbreviated as DOL, is perhaps the most traditional system and consists in connecting the motor directly to the supply network, thus carrying out starting at full voltage.Direct-on-line starting represents the simplest and the most economical system to start a squirrel-cage asynchronous motor and it is the most used.
As represented in Figure 5, it provides the direct connection to the supply network and therefore starting is carried out at full voltage and with constant frequency, developing a high starting torque with very reduced acceleration times.
The typical applications are relevant to small power motors also with full load starting.
These advantages are linked to some problems such as, for example, the high inrush current, which - in the first instants - can reach values of about 10 to 12 times the rated current, then can decrease to about 6 to 8 times the rated current and can persist to reach the maximum torque speed.The effects of such currents can be identified with the high electro-dynamical stresses on the motor connection cables and could affect also the windings of the motor itself; besides, the high inrush torques can cause violent accelerations which stress the transmission components (belts and joints) generating distribution problems with a reduction in the mechanical life of these elements.
Finally, also the possible electrical problems due to voltage drops on the supply line of the motor or of the connected equipment must be taken into consideration.
[ABB]Прямой пуск
Прямой пуск, который по-английски часто сокращенно обозначают как DOL, является, пожалуй наиболее распространенным способом пуска. Он заключается в непосредственном (т. е. прямом) подключении двигателя к питающей сети. Это означает, что пуск двигателя осуществляется при полном напряжении.Схема прямого пуска является наиболее простым, экономичным и чаще всего применяемым решением для электродвигателей с короткозамкнутым ротором.
Схема прямого подключения к сети представлена на рисунке 5. Пуск осуществляется при полном напряжении и постоянной частоте сети. Электродвигатель развивает высокий пусковой момент при коротком времени разгона.
Типичные области применения – маломощные электродвигатели, в том числе с пуском при полной нагрузке.
Однако, наряду с преимуществами имеются и определенные недостатки, например, бросок пускового тока, достигающий в первоначальный момент 10…12-кратного значения от номинального тока электродвигателя. Затем ток двигателя уменьшается примерно до 6…8-кратного значения номинального тока и будет держаться на этом уровне до тех пор, пока скорость двигателя не достигнет максимального значения.
Такое изменение тока оказывает значительное электродинамическое воздействие на кабель, подключенный к двигателю. Кроме того пусковой ток воздействует на обмотки двигателя. Высокий начальный пусковой момент может привести к значительному ускорению и следовательно к значительной нагрузке элементов привода (ремней, крепления узлов), что вызывает сокращение их срока службы.
И, наконец, следует принять во внимание возможное возникновение проблем, связанных с падением напряжения в линии питания двигателя и подключенного к этой линии оборудования.

These advantages are linked to some problems such as, for example, the high inrush current, which - in the first instants - can reach values of about 10 to 12 times the rated current, then can decrease to about 6 to 8 times the rated current and can persist to reach the maximum torque speed.The effects of such currents can be identified with the high electro-dynamical stresses on the motor connection cables and could affect also the windings of the motor itself; besides, the high inrush torques can cause violent accelerations which stress the transmission components (belts and joints) generating distribution problems with a reduction in the mechanical life of these elements.
Finally, also the possible electrical problems due to voltage drops on the supply line of the motor or of the connected equipment must be taken into consideration.
[ABB]Прямой пуск
Прямой пуск, который по-английски часто сокращенно обозначают как DOL, является, пожалуй наиболее распространенным способом пуска. Он заключается в непосредственном (т. е. прямом) подключении двигателя к питающей сети. Это означает, что пуск двигателя осуществляется при полном напряжении.Схема прямого пуска является наиболее простым, экономичным и чаще всего применяемым решением для электродвигателей с короткозамкнутым ротором.
Схема прямого подключения к сети представлена на рисунке 5. Пуск осуществляется при полном напряжении и постоянной частоте сети. Электродвигатель развивает высокий пусковой момент при коротком времени разгона.
Типичные области применения – маломощные электродвигатели, в том числе с пуском при полной нагрузке.
Однако, наряду с преимуществами имеются и определенные недостатки, например, бросок пускового тока, достигающий в первоначальный момент 10…12-кратного значения от номинального тока электродвигателя. Затем ток двигателя уменьшается примерно до 6…8-кратного значения номинального тока и будет держаться на этом уровне до тех пор, пока скорость двигателя не достигнет максимального значения.
Такое изменение тока оказывает значительное электродинамическое воздействие на кабель, подключенный к двигателю. Кроме того пусковой ток воздействует на обмотки двигателя. Высокий начальный пусковой момент может привести к значительному ускорению и следовательно к значительной нагрузке элементов привода (ремней, крепления узлов), что вызывает сокращение их срока службы.
И, наконец, следует принять во внимание возможное возникновение проблем, связанных с падением напряжения в линии питания двигателя и подключенного к этой линии оборудования.
