Description
Насто щее изобретение относитс к устройствам дл измерени сдвига фаз между токами в дифференциально-фазной, высокочастотной защите линий, содержащим приемопередатчики, установленные на обоих концах защищаемой линии и манипулирующие высокочастотные сигналы токами промышленной частоты.The present invention relates to devices for measuring the phase shift between currents in a differential-phase, high-frequency protection of lines, comprising transceivers installed at both ends of the protected line and manipulating high-frequency signals with industrial frequency currents.
Предлагаемое устройство отличаетс от известных тем, что в нем применен интегрирующий контур, включенный через диод в цепь приемника и содержащий конденсатор и включенное параллельно ему сопротивление. К выходу этого контура через полупроводниковый триод подключено реле.The proposed device differs from the known ones in that it uses an integrating circuit, connected via a diode to the receiver circuit and containing a capacitor and a resistance connected in parallel with it. A relay is connected to the output of this circuit through a semiconductor triode.
Такое выполнение устройства позвол ет значительно упростить его схему.Such an embodiment of the device makes it possible to significantly simplify its scheme.
На фиг. 1 и .2 изображены электрические схемы предлагаемого устройства в двух вариантах исполнени .FIG. 1 and .2 depict the electric circuits of the device proposed in two versions.
Устройство состоит из триода Г (фиг. 1) с заземленным эмиттером , база которого приключена к движку потенциометра R. Параллельно потенциометру включен конденсатор С. Потенциометр и конденсатор получают питание от приемника высокочастотной, защиты через диод D. В цепь коллектора триода включено выходное реле Р защиты.The device consists of a triode G (Fig. 1) with a grounded emitter, the base of which is connected to the engine of potentiometer R. Parallel to the potentiometer, capacitor C is turned on. protection.
Триод Г нормально закрыт положительным потенциалом на базе . При подаче к устройству отрицательных импульсов от высокочастотного приемника происходит зар д конденсатора С, открытие триода TI и срабатывание реле Р.Triode G is normally closed with a positive potential at the base. When negative pulses are fed to the device from a high-frequency receiver, capacitor C is charged, TI triode is opened, and relay P is triggered.
Дл увеличени крутизны фазовой характеристики может быть применен дополнительный триод TZ, работающий по схеме эмиттерного повторител (фиг. 2).To increase the phase response slope, an additional triode TZ can be used, which operates according to the emitter follower circuit (Fig. 2).
