Abstract

Устройство для автоматического переключения с основного электроагрегата постоянного тока на дублирующий, например электродвигателей вентиляторов, содержащее блоки защиты и коммутационные элементы в цепях их питания, отличающееся тем, что, с целью повышения эксплуатационной надежности за счет исключения вращения колеса отключенного вентилятора, в него введено промежуточное реле с контактами, обмотка которого подключена параллельно выходу блока защиты основного электродвигателя, а контакты реле включены на выходе блока защиты дублирующего электродвигателя, при этом коммутационный элемент дублирующего электродвигателя связан с блоком защиты основного электродвигателя.A device for automatic switching from the main DC electrical unit to the backup one, for example, fan electric motors, containing protection blocks and switching elements in their power supply circuits, characterized in that, in order to increase operational reliability by eliminating the rotation of the fan off wheel, an intermediate relay with contacts, the winding of which is connected in parallel with the output of the main motor protection unit, and the relay contacts are connected at the output of the duplicate protection unit uyuschego motor, the switching element of the backup motor is connected with the main motor protection unit.
