Claims (2)

1. Устройство защиты погружного насосного агрегата, содержащее погружной электродвигатель (ПЭД), включенный в трехфазную силовую цепь с изолированной нейтралью посредством прерывателя силового питания с блоком управления, трансформатором питания ПЭД и силового кабеля с экраном, устройство контроля изоляции кабеля, связанное по исполнительной цепи с блоком управления и по входной цепи с нулевой точкой вторичной обмотки трансформатора питания ПЭД, погружное устройство, включающее в себя как минимум один датчик параметров, с выходной частью, подключенной к силовой цепи ПЭД и экрану кабеля, отличающееся тем, что, с целью повышения надежности в работе, существенного упрощения и удешевления оборудования, выходная часть погружного устройства выполнена в виде ключа, включенного гальванически между силовой цепью ПЭД и экраном силового кабеля.1. The protection device of a submersible pump unit, comprising a submersible electric motor (SEM) included in a three-phase power circuit with an isolated neutral by means of a power supply interrupter with a control unit, a SEM power transformer and a power cable with a shield, a cable insulation control device connected via an executive circuit with the control unit and the input circuit with a zero point of the secondary winding of the power transformer PED, an immersion device that includes at least one parameter sensor, with an output hour a plug connected to the power circuit of the SEM and the cable screen, characterized in that, in order to increase reliability in operation, significantly simplify and reduce the cost of equipment, the output part of the submersible device is made in the form of a key connected galvanically between the power circuit of the SEM and the screen of the power cable. 2. Устройство по п.1, отличающееся тем, что ключ имеет сопротивление в режиме заданных допустимых параметров датчика (датчиков) выше сопротивления срабатывания устройства контроля изоляции, а в режиме отклонения от заданных допустимых параметров датчика (датчиков) имеет сопротивление ниже сопротивления срабатывания устройства контроля изоляции.2. The device according to claim 1, characterized in that the key has a resistance in the mode of preset allowable parameters of the sensor (s) above the response resistance of the insulation monitoring device, and in the mode of deviation from the set permissible parameters of the sensor (s), it has a resistance below the response resistance of the control device isolation.
