Claims (2)

1. Способ защиты управляемого подмагничиванием реактора от внутренних коротких замыканий, заключающийся в том, что при появлении переменного напряжения между электрически уравновешенными по переменному току точками обмоток управления реактора, соединенных в треугольник, к которым подключается внешний источник постоянного тока, в дополнительно подключенных тиристорах на выводах источника подмагничивания и в трансформаторе тока, охватывающем их ошиновку, появляется ток, приводящий к срабатыванию максимального токового реле и подаче сигнала на отключение реактора и его системы управления.1. A method of protecting a reactor controlled by magnetization from internal short circuits, which consists in the fact that when an alternating voltage appears between the points of the reactor control windings electrically balanced by alternating current connected in a triangle to which an external DC source is connected, in additionally connected thyristors at the terminals bias source and in the current transformer, covering their busbar, a current appears, leading to the operation of the maximum current relay and supply Igna reactor shutdown and control system. 2. Устройство защиты управляемого подмагничиванием реактора от внутренних коротких замыканий для осуществления способа по п.1, содержащее два встречно-параллельно включенных неуправляемых тиристора или стабилитрона на выводах внешнего источника подмагничивания реактора, трансформатор тока, охватывающий ошиновку этих тиристоров или стабилитронов, и максимальное токовое реле, подключенное на вторичную обмотку трансформатора тока и действующее своими выходными контактами на отключение сетевого выключателя и системы управления реактора. 2. The device for protecting the reactor controlled by magnetization from internal short circuits for implementing the method according to claim 1, comprising two counter-parallel connected uncontrolled thyristors or a zener diode at the terminals of an external source of magnetization of the reactor, a current transformer covering the busbar of these thyristors or zener diodes, and a maximum current relay connected to the secondary winding of the current transformer and acting with its output contacts to disconnect the network switch and the react control system pa.
