Description

Известны устройства дл  сигнализации и защиты при по влении обратных токов в цеп х тюсто нного тока, например при обратных зажигани х ртутных выпр мителей с использованием электрического импульса , возникающего при изменении тока в проводе на обратный.Signaling and protection devices are known for the occurrence of reverse currents in a tail current circuit, for example, with a reverse ignition of a mercury rectifier using an electrical impulse that occurs when the current in the wire changes to reverse.

Предлагаемое устройство отличаетс  от известных тем, что в нем применены два надетых на токонесущий провод замкнутых магнитных сердечника, предварительно подмагничениых в противоположных направлени х и снабженных импульсными измерительными обмотками, сигналы напр жени  которых поданы через запирающие выпр мители на суммирующий потенциометр, к выходу которого подключена триггерна  схема на полупроводниках, предназначенна  дл  включени  одной из двух сигнальных ламп при измерении на обратное направление тока в контролируемом проводе.The proposed device differs from the known ones in that it uses two closed magnetic cores, mounted on a current-carrying wire, which are premagnetized in opposite directions and equipped with pulsed measuring windings, the voltage signals of which are applied through a locking rectifier to a summing potentiometer, to the output of which a trigger is connected a semiconductor circuit designed to turn on one of the two signal lamps when measured in the opposite direction of the current in a controlled ode.

Такое выполнение устройства позвол ет повысить его быстродействие .Such an embodiment of the device makes it possible to increase its speed.

На чертеже изображена схема устройства.The drawing shows a diagram of the device.

Устройство служит дл  сигнализации о возникновении обратного зажигани  в каждом отдельном вентиле и содержит два магнитных сердечника Ci и С, надеваемых на контролируемый токонесущий провод П. Каждый из сердечников снабжен двум  обмотками W и Wz, при этом одна из обмоток каждого сердечника служит дл  подмагничивани  их вспомогательным посто нным током в противоположных направлени х.The device serves to signal the occurrence of a reverse ignition in each individual valve and contains two magnetic cores Ci and C mounted on a controlled current-carrying wire P. Each of the cores is equipped with two windings W and Wz, and one of the windings of each core is used to bias them with an auxiliary direct current in opposite directions.

При протекании по проводу Я рабочего тока в необходимом на правлении один из сердечников намагнититс  до насыщени , а второй перемагнититс  в обратном направлении до того же значени . При возникновении в проводе обратного тока происходит перемагничивание сердечников в обратном направлении. Дл  фиксации импульсов, возникающих во вторичных обмотках W сердечников при изменении направлени  тока в проводе, применена триггерна  схема на полупроводWhen the working current flows along the I wire in the required direction, one of the cores magnetizes to saturation, and the second one magnetizes in the opposite direction to the same value. When reverse current occurs in the wire, the cores re-magnetize in the opposite direction. To fix the pulses that occur in the secondary windings of the W cores when the current in the wire changes, a trigger circuit on the semiconductor is used.
