Claims (2)

1. Устройство присоединения аппаратуры связи к кабелю электропередачи, содержащее трансформатор, выполненный на кольцевом сердечнике, вторичная обмотка которого образована путем пропускания проводника, заземляющего бронирующую оплетку и металлическую оболочку кабеля электропередачи, через кольцевой сердечник с намотанной на нем первичной обмоткой, один вывод первичной обмотки трансформатора соединен с заземленной аппаратурой связи, а второй вывод заземлен, отличающееся тем, что токоведущие жилы кабеля электропередачи заземлены через конденсаторы.1. A device for connecting communication equipment to a power cable, containing a transformer made on an annular core, the secondary winding of which is formed by passing a conductor grounding the armor braid and the metal sheath of the power cable, through an annular core with a primary winding wound on it, one terminal of the transformer primary winding connected to a grounded communication equipment, and the second terminal is grounded, characterized in that the live conductors of the power cable are grounded through es capacitors. 2. Устройство присоединения аппаратуры связи к кабелю электропередачи по п.1, отличающееся тем, что последовательно с конденсаторами включены индуктивности, образующие резонансный контур, настроенный на частоту ВЧ-сигнала.2. The device for connecting the communication equipment to the power cable according to claim 1, characterized in that inductors are connected in series with the capacitors, forming a resonant circuit tuned to the frequency of the RF signal.
