Description
многотактного реверсивного ключа, к выходам которого подключена обмотка подмагничивани дроссел .a multi-tact reversing key, to the outputs of which a magnetic bias winding is connected.
На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
В схему вход т компенсирующий дроссель 1 с обмоткой подмагничива-г НИН NJVv, , блок выделени знака прира )дени ;2, подклю енный к допрлнительнбй обмотке дроссел , низковольтовый , ,.,нepaтop импульсов 3, выход KOTOOTiro подключен к первьлм входам логических элементов И 4, 5, вторые входы которых соединены с выходами плюс и минус блока вьщелени знака приращени 2, а выходы элементов И 4, 5 подключены соответственно к управл ющим входам плюс и минус многотактного реверсивного ключа б, к выходам которого подключена обмотка подмагничивани дроссел .The circuit includes a compensating choke 1 with a bias magnetic winding NINV Nv, unit for the selection of the sign of the prefix date; 2, connected to the additional winding of the choke, low voltage,. 4, 5, the second inputs of which are connected to the outputs plus and minus of the block of the increment sign 2, and the outputs of the And 4, 5 elements are connected respectively to the control inputs plus and minus of the multi-action reversing switch b, to the outputs of which the magnetic stray winding is connected.
Схема работает следующим образом.The scheme works as follows.
Компенсирующий дроссель 1 включен в нейтраль электрической сети. Напр жение с сигнальной обмотки поступает в блок выделени знака приращени 2. В момент - включени блок наделени знака приращени может находитьс в любом состо нии. Если первый импульс с генератора импульсов 3 уменьшит напр жение сигнальной обмотки, то срабатывает блок выделени знака приращени , С этого момента напр жение сигнальной обмотки будет увеличиватьс , В момент перехода максимума напр жени сигнальной обмотки снова сработает блок выделени знака приращени и перейдет в другое состо ние, И таким образом все врем напр жение будет колебатьс около положени максимума . Этим достигаетс настройка компенсирующего дроссел в резонанс с.емкостью электрической сети. В момент касани одной из фаз или замыкани одной из фаз на корпус электроГ 9,°The compensating choke 1 is connected to the neutral of the electrical network. The voltage from the signal winding enters the block for the selection of the increment sign 2. At the moment of switching on, the block for endowing the sign of the increment can be in any state. If the first pulse from the pulse generator 3 reduces the voltage of the signal winding, the increment sign extracting unit triggers. From this moment the voltage of the signal coil will increase. And so all the time the voltage will fluctuate around the position of the maximum. This is achieved by adjusting the compensating throttle to resonance with the capacity of the electrical network. At the moment of contact of one of the phases or the closure of one of the phases on the housing of the electroGeneral 9, °
оборудовани срабатьшает реле защиты устройства,которое отключает схему от сигнальной обмотки и прерывает подачу сигналов от генератора импуль .сов.В случае, какого-либо сбо работы устройства предусмотрен реверс регул тора многотактного реверсивного ключа,перевод щий схему из одного крайнего состо ни в другое.The equipment triggers the device protection relay, which disconnects the circuit from the signal winding and interrupts the signals from the pulse generator. In the event of any device malfunction, a reversing multivariate reversing key regulator is provided that takes the circuit from one extreme state to another.
