Description
(54) УСТРОЙСТВО ДЛЯ СОЗДАНИЯ ИСКУССТВЕННОГО КОРОТКОГО ЗАМЫКАНИЯ НА ВОЗДУШНОЙ ЛИНИИ ЭЛЕКТРОПЕРЕдаЧИ(54) DEVICE FOR CREATING ARTIFICIAL SHORT CIRCUIT ON AIRLINE ELECTRICAL TRANSMISSION LINES
2 защищаемой линии, и крепитс кронштейном 3 к корпусу 4, электрически св занного/ проводником 5 с э.г1ементом , электрический потенциал которого отличен отпотенциала провода 2, например, с проводом другой фазы.2 of the line to be protected, and is fastened with a bracket 3 to the housing 4 electrically connected / conductor 5 with the electrical circuit, the electric potential of which is different from the potential of the wire 2, for example, with the wire of another phase.
При обрыве любого провода он падает на металлический электрод 1, |вследствие чего возникает надежное металлическое короткое замыкание между упавшим проводом и проводом другой фазы. Защитный токовый элемент, установленный в начале линии, ера- батывает. Аналогично устройство работает при соединении электродов с землей или арматурой изол тора.When any wire is broken, it falls on the metal electrode 1, so that a reliable metal short circuit occurs between the fallen wire and the wire of another phase. The protective current element installed at the beginning of the line is working. Similarly, the device works by connecting the electrodes to the ground or the insulator fittings.
За счет установки электродов отдельно под каждым проводом достигаетс больша веро тность .контакта упавшего провода и электрода и обеспечиваетс возможность использовант устройства в сет х с изолированной нейтралью.By installing the electrodes separately under each wire, a greater probability of contact of the fallen wire and electrode is achieved, and it is possible to use devices in networks with an insulated neutral.
