Использование: низковольтные автоматические выключатели. Сущность: электромагнитный расцепитель содержит П-образную магнитную систему, основную намагничивающую обмотку, питаемую током защищаемой цепи, и дополнительную намагничивающую обмотку, питаемую током цепи управления. Обмотки размещены на двухсекционном каркасе, их начала соединены наконечником и они включены согласно (имеют одинаковое направление намотки провода). Увеличение тока в цепи управления при возникновении в ней тока короткого замыкания приводит к увеличению магнитного потока и силы, воздействующей на якорь. Якорь, преодолевая противодействующее усилие пружины, перемещается до соприкосновения со стопом и перемещает толкатель, воздействующий на рейку механизма свободного расцепления. Положительный эффект: обеспечение защиты цепи управления от токов короткого замыкания при сохранении защитных функций для главной цепи.Use: low-voltage circuit breakers. Essence: the electromagnetic release contains a U-shaped magnetic system, the main magnetizing winding, fed by the current of the protected circuit, and the additional magnetizing winding, fed by the current of the control circuit. The windings are placed on a two-section frame, their beginnings are connected by a tip and they are connected according to (they have the same direction of winding the wire). An increase in the current in the control circuit when a short circuit current occurs in it leads to an increase in the magnetic flux and force acting on the armature. Anchor, overcoming the opposing force of the spring, moves to the contact with the stop and moves the pusher acting on the rail of the mechanism of free tripping. Positive effect: ensuring the protection of the control circuit against short-circuit currents while maintaining the protective functions for the main circuit.
