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.
