Description

Предметом насто щего изобретенп   вл етс  защитное устройство дл  автоматического выключени  высоковольтного рад1говещательного фидера при аварии (обрыв пли заземление липни).The subject of the present invention is a protective device for automatically switching off a high-voltage radio broadcasting feeder in the event of an accident (open or broken ground).

Известны способы защиты радиовещательной линии: создание искусственных средних точек иа коицах защип1,аемой лиипи и включепио между ПИМ11 отключающего реле, расиоложениогй в месте устанонкп автоматического выключател .There are known methods for protecting a broadcasting line: the creation of artificial midpoints on the terminals of the taper1, aemy line, and on between the PIM11 tripping relay, located in the place of the automatic switch installation.

В описываемом устройстве, с целью иовыизени  чувствительности защиты, указанна  искусственна  цепь Шхлючаетс  носледовательно с емкость о и: индуктивностью в плечо сбалансированного моста, питаемого неременным током; реле защиты включаетс  в диагональ этого же моста.In the described device, in order to determine the sensitivity of the protection, the specified Artificial Shchlyuchaetsya circuit with the capacitance O and: inductance in the shoulder of a balanced bridge fed by a non-temporal current; protection relay is included in the diagonal of the same bridge.

Как видно из чертежа, в устройстве использованы цень «два ироЕода-земл , дополненна  дросселем 1 и конденсатором 2 в одном плече моста, и балансный контур 3 из дроссел , конденсатора и переменного сопротивлепи  4-в другом плече моста.As can be seen from the drawing, the device uses the price of “two iROEOEds-earth, supplemented by choke 1 and capacitor 2 in one arm of the bridge, and balanced circuit 3 made of droselle, capacitor and variable resistance 4 in the other arm of the bridge.

Дроссель 1 предназначен дл  предотвращенн  ложных срабатываний защитного устройства от воздействи  на него токов частотного сиектра передачи, которые могут по витьс  в цепи «два провода-земл  при наличии асимметрии в линии. Заземление средней точки на удаленном конце системы «два провода-земл  через конденсатор 2 обеспечивает возможность проверки пзол ции линии иередачи посылкой в нее посто нного тока.The choke 1 is designed to prevent false positives of the protective device from being influenced by currents of the transmission frequency spectrum, which can appear in a two-ground-circuit in the presence of asymmetry in the line. Grounding the midpoint at the remote end of the system “two wires-ground through the capacitor 2 provides the ability to check the isolation of the line and the transmission by sending a direct current to it.

В диагональ моста включены выпр митель 5 и реле защиты 6, выключающее фидер 7. Каждое плечо моста настроено приблизительно Б резонанс на частоту питающего систему защиты напр жени , подаваемого через трансформатор 8.The bridge diagonal includes a rectifier 5 and a protection relay 6, which turns off the feeder 7. Each bridge arm is tuned approximately B to resonance at the frequency of the voltage protection system supplied through the transformer 8.
