Abstract
Устройство контроля непрерывности нулевых проводников в линиях 0,38 кВ, содержащее силовой трансформатор, заземленная нейтраль которого через нулевой рабочий проводник соединена с однофазными потребителями, а через нулевой защитный проводник заземленная нейтраль трансформатора соединена с корпусами электрооборудования, отличающееся тем, что введены однофазный двухобмоточный трансформатор, первичная обмотка которого включена в рассечку нулевого рабочего проводника и соединена посредством резистора и кнопки с фазным проводом, а вторичная обмотка трансформатора соединена последовательно с реагирующим органом, воздействующим на сигнальный элемент, и включена в рассечку нулевого защитного проводника, выход которого соединяется с заземляющим устройством.A device for monitoring the continuity of neutral conductors in 0.38 kV lines, containing a power transformer, the grounded neutral of which is connected to single-phase consumers through a neutral working conductor, and through the protective conductor, the grounded neutral of the transformer is connected to the electrical equipment housings, characterized in that a single-phase double-winding transformer is introduced, the primary winding of which is included in the cut of the zero working conductor and is connected by means of a resistor and a button to a phase wire, and the second The transformer’s winding is connected in series with the reacting body acting on the signal element and is included in the cut-out of the zero protective conductor, the output of which is connected to the grounding device.
