Description

Предлагаемое изобретение относитс  к устройствам дл  одновременной передачи одной и той же программы по радио и по проводам с питанием трансл ционной линии от одной из ступеней передатчика через трансформатор или при посредстве реактивного или ваттного сопротивлени , включаемого в линию прохождени  тока звуковой частоты. Согласно изобретению, дл  целей лучшего обеспечени  безопасности линии от перенапр|Яжений , могущих возникнуть в случае какой - либо аварии с передатчиком, параллельно вводимому в цепь прохождени  тока звуковой частоты в передатчике сопротивлению, либо вторичной обмотке трансформатора, присо един ютс , включенные между собой последовательно-конденсатор и реактивна  катушка . К зажимам этой катушки присоедин етс  лини . Реактивна  катушка рассчитываетс  так, чтобы в случае перенапр жений на зажимах сопротивлени  или в первичной цепи трансформатора возрастание тока в шунтирующей катушке вызывало бы насыщение сердечника этой катушки и, вследствие падени  на232The present invention relates to devices for simultaneous transmission of the same program over the radio and by wire with the power of a transmission line from one of the transmitter stages through a transformer or through reactive or watt impedance included in the audio current frequency transmission line. According to the invention, in order to better ensure the safety, lines from overvoltages, which may occur in the event of any accident, with a transmitter in parallel with the impedance of the transmitter, or the secondary winding of the transformer, are connected in parallel with the transmitter capacitor and reactive coil. A line is attached to the terminals of this coil. The reactive coil is calculated so that in case of overvoltages on the resistance terminals or in the primary circuit of the transformer, an increase in the current in the shunt coil would cause the core of this coil to saturate and, due to a drop in 222
