Description
(5) УСТРОЙСТВО ДЛЯ ЗАЩИТЫ ПРЕОБРАЗОВАТЕЛЯ(5) DEVICE FOR PROTECTION PROTECTION
1one
Изобретение относитс к электротехнике и может быть использовано дл защиты управл емых выпр мителей от короткого замыкани на стороне посто нного тока.This invention relates to electrical engineering and can be used to protect controlled rectifiers from short-circuiting on the DC side.
Известно устройство дл защиты преобразовател на основе трансформатора посто нного тока, содержащее два сердечника, через отверсти которых пропущен один из проводов посто нного тока. На сердечниках расположены обмотки, которые соединены последовательно и подключены к источнику переменного напр жени стандартной частоты 1 .A device for protecting a converter based on a DC transformer, comprising two cores, through the openings of which one of the DC wires is passed, is known. On the cores there are windings that are connected in series and connected to a standard voltage alternating voltage source 1.
Недостатком устройства вл етс необходимость в перенастройке уставки защиты при изменении режима работы нагрузки или преобразовател .The drawback of the device is the need to reconfigure the protection setpoint when changing the operating mode of the load or converter.
Наиболее близким к предлагаемому по технической сущности вл етс устройство дл защиты преобразовател , содержащее включенный между шинами посто нного тока конденсатор, два установленных на шине посто нного тока сердечника, обмотка первого из которых подключена к цепи управлени тиристора реагирующего органа, а обмотка второго выполнена со среднейThe closest to the proposed technical entity is a device for protection of the converter, containing a capacitor connected between the DC buses, two installed on the DC bus of the core, the winding of the first of which is connected to the control circuit of the thyristor of the reacting organ, and the winding of the second is made from the middle
5 точкой, и генератор высогтой частоты выполненный в виде мультивибратора, причем средн точка обмотки подключена к одной из клемм источника питани мультивибратора, а ее концы - к5 point, and a high frequency generator made in the form of a multivibrator, the middle point of the winding being connected to one of the terminals of the multivibrator power source, and its ends to
О транзисторам мультивибратора 2.About multivibrator transistors 2.
Недостатком устройства вл етс мала мощность высокочастотных колебаний в обмотке из-за большой ин15 дуктивности ее секций, вследствие чего магнитный поток в сердечнике становитс недостаточным дл создани такого напр жени на входе реагирующего органа, которое способно The drawback of the device is the low power of high-frequency oscillations in the winding due to the high inductance of its sections, as a result of which the magnetic flux in the core becomes insufficient to create such a voltage at the input of the reacting organ that is capable of
20 обеспечить надежную работу устройства .20 to ensure reliable operation of the device.
