Description
Изобретение относитс к области передачи телемеханической информации с использованием силовых сетей электроснабжени в качестве линии св зи.The invention relates to the field of telemechanical information transmission using power supply networks as a communication link.
Известно устройство высокочастотного обхода дл линий св зи по кабельной сети электроснабжени , содержащее трансформаторные устройства присоединени н трансформатор св зи.A high-frequency bypass device for communication lines over a power supply cable network is known, which contains transformer connection devices and a communication transformer.
Недостатком такого устройства вл етс сложность конструкции.The disadvantage of this device is the complexity of the design.
Цель изобретени - упрощение конструкции высокочастотного обходного устройства.The purpose of the invention is to simplify the design of the high-frequency bypass.
Поставленна цель достигаетс тем, что в этом устройстве трансформатор св зи первичной об.моткой через броню входного отрезка кабел и заземлител соединен со вторичной обмоткой входного трансформатора присоединени , а вторичной обмоткой - через броню входного отрезка кабел и заземлители - с первичной обмоткой выходного трансформатора присоединени .The goal is achieved by the fact that in this device the primary voltage transformer is connected through the armor of the input cable segment and the earthing switch is connected to the secondary winding of the input transformer of the terminal, and the secondary winding through the armor of the input cable section and grounding wires to the primary winding of the output transformer of the connection transformer.
Устройство показано на чертеже.The device is shown in the drawing.
Устройство обхода, например выключател , состоит из двух, настраиваемых в резонанс конденсаторами 1 трансформаторов нрнсоединепи 2 н 3, переходного трансформатора 4 и двух монтажных отрезков бронированного кабел 5, расположенных с обоих сторон от выключател 6.The bypass device, for example, a switch, consists of two transformers nrnodneepi 2 n 3 that are tuned in resonance by capacitors 1, a transition transformer 4, and two mounting pieces of armored cable 5 located on both sides of switch 6.
Высокочастотные сигналы по трем силовым жилам от источника питани проход т через первичную обмотку первого трансформатора присоединени 2 и навод тс во вторичной обмотке . К.п.д. трапсформатора, в осповпом, будет зависеть от еопротпвлени шунта, замыкающего вторичную обмотку со стороны места разрыва лнннн 6 на землю. Функцию щунта выполн ет в данном случае монтажный отрезок кабел 5. Одновременно но его броне передаетс сигнал до переходного трансформатора 4. Со вторнчной обмотки переходного трапсформатора сигнал но второму контуру «брон кабел - земл нередаетс во второеHigh-frequency signals along the three power conductors from the power source pass through the primary winding of the first transformer of connection 2 and are induced in the secondary winding. Kpd The trapsformator, in small scale, will depend on the shunt closing the secondary winding from the side of the interruption lnnn 6 to the ground. The function of the shunt is performed in this case by the installation section of the cable 5. At the same time, a signal is transmitted to its armor to the transition transformer 4. From the secondary winding of the transition trapsformer, the signal is transmitted to the second circuit of the bronze cable - the ground
