Abstract
Изобретение относитс к электроавтоматике и может найти применение при коммутации индуктивных нагрузок. Цель изобретени - повышение надежности, быстродействи и расширени эксплуатационных возможностей. При замыкании коммутационного элемента импульсы тока, возникающие из-за дребезга контактов коммутационного элемента, подаютс в нагрузку и на зар д конденсатора. В моменты отсутстви импульсов конденсатор разр жаетс через нагрузку, поддержива в ней посто нный ток. При размыкании коммутационного элемента энерги , накопленна в конденсаторе, переходит через третий диод 6 в нагрузку, что уменьшает ЭДС самоиндукции за счет цепи из последовательно включенных четвертого диода 7 и резистора 9. 3 ил.The invention relates to electroautomatic and can be used when switching inductive loads. The purpose of the invention is to increase reliability, speed and increase operational capabilities. When the switching element is closed, the current pulses arising from the bounce of the contacts of the switching element are applied to the load and to the charge of the capacitor. At the moments when there are no pulses, the capacitor discharges through the load, maintaining a constant current in it. When the switching element is opened, the energy stored in the capacitor passes through the third diode 6 to the load, which reduces the self-induced EMF due to a circuit from the fourth diode 7 connected in series and the resistor 9. 3 Il.
