Это устройство имеет низкую надежность.This device has low reliability.
Известно также переключающее устройство, содержащее вольтодобавочный трансформатор и ключевые элементы, выполненные, например, на встречно-параллельно включенных тиристорах 2.It is also known switching device containing the booster transformer and key elements made, for example, on anti-parallel thyristors 2.
Это устройство также имеет низкую надежность .This device also has low reliability.
Цель изобретени - повыщение надежности .The purpose of the invention is to increase reliability.
Эта цель достигаетс тем, что в предлагаемом переключающем устройстве магнитна система вольтодобавочного трансформатора выполнена в виде магнитообъемной конструкции, имеющей один общий керн и п кернов, на которых намотаны две группы обмоток, каждый из выводов первой гр}ппы обмоток соединен.This goal is achieved by the fact that, in the proposed switching device, the magnetic system of booster transformer is made in the form of a magnetic core structure having one common core and cores on which two groups of windings are wound, each of the terminals of the first group of windings is connected.
через ключевые элементы с шинами питани , а обмотки второй группы соединены последовательно и включены в цепь нагрузки, при этом обмотки второй группы имеют соотношение чисел витков 1:3:9.....through the key elements with the power rails, and the windings of the second group are connected in series and included in the load circuit, while the windings of the second group have the ratio of the numbers of turns 1: 3: 9 .....
На чертеже показана схема предлагаемого устройства применительно к сердечнику, имеющему один общий керн и три керна с питающими обмотками.The drawing shows a diagram of the proposed device in relation to the core having one common core and three cores with supply windings.
Устройство имеет вольтодобавочный трансформатор 1, магнитна система которого содержит один общий керн и три керна, на которых нанесены обмотки 2-4 и 5-7. Обмотки 2-4 подключаютс к питающей сети с помощью тиристорных ключей 8-19. Обмотки 5-7, соединенные последовательно, имеют соотнощение чисел витков 1:3:9 и включаютс в контур нагрузки с помощью зажимов 20 и 21. Тиристорные ключи реализуют три состо ни сетевых обмоток 2-4. Например обмотка 2 может быть с помощью тиристорных ключей включена пр мо - включены ключи 8 и 11, реверсно-включены ключи 9 и 10 или закорочены-включены ключи 8 и 10. Аналогично могут быть включены обмотки 3 и 4.The device has a booster transformer 1, the magnetic system of which contains one common core and three cores, on which windings 2-4 and 5-7 are applied. The windings 2-4 are connected to the mains using thyristor switches 8-19. The windings 5-7, connected in series, have a ratio of 1: 3: 9 turns and are included in the load circuit using clamps 20 and 21. The thyristor keys realize three states of the network windings 2-4. For example, winding 2 can be switched on using thyristor keys directly — keys 8 and 11 are turned on, keys 9 and 10 are reverse-turned on, and keys 8 and 10 are short-circuited — keys 3 and 4 can be turned on in the same way.
Выходное напр жение устройства формируетс путем алгебраического суммировани электродвижущих сил обмоток 5-7. Устройство реализует на выходе равномерный дискретный р д числовых значений выходного напр жени с числом позиций 3 .The output voltage of the device is formed by algebraically summing the electromotive forces of the windings 5-7. The device implements at the output a uniform discrete series of numerical values of the output voltage with the number of positions 3.
Применение магнитообъемной конструкции позвол ет уменьшить габарит -установки и повысить его надежность за счет сокращени числа ключевых элементов в расчете на одну позицию. Эти преимущества заметно про вл ютс при необходимости создани переключающего устройства с большим числом ступеней.The use of a magnetic construction reduces the size of the installation and increases its reliability by reducing the number of key elements per position. These advantages are noticeably manifested when it is necessary to create a switching device with a large number of stages.
