Abstract
Устройство защиты от однофазного замыкания на землю в сети с изолированной нейтралью, содержащее кольцеобразный магнитопровод, охватывающий проводники сети, и реле тока, отличающееся тем, что кольцеобразный магнитопровод имеет поперечный воздушный зазор с перпендикулярным ему тангенциальным сквозным отверстием и радиальное несквозное отверстие, ось вращения которого проходит через середину этого зазора, а реле тока выполнено в виде геркона и постоянного магнита в тангенциальном сквозном и радиальном несквозном отверстиях соответственно, при этом постоянный магнит может поворачиваться вокруг оси радиального отверстия, а контакты геркона подключены к отключающей цепи выключателя или сигнализации.A device for protecting against a single-phase earth fault in an insulated neutral network, containing an annular magnetic circuit covering the network conductors, and a current relay, characterized in that the annular magnetic circuit has a transverse air gap with a tangential through hole perpendicular to it and a radial through hole, the axis of rotation of which passes through the middle of this gap, and the current relay is made in the form of a reed switch and a permanent magnet in the tangential through and radial through holes respectively In fact, in this case, the permanent magnet can rotate around the axis of the radial hole, and the contacts of the reed switch are connected to the disconnecting circuit of the switch or alarm.
