Description
и вызывает размыкание контакта 2 или 3. Питание с электромагнитного клапана 4 снимаетс и через последовательную цепь, составленную из искрогас щего диода 10, резистора 12 и стабилитрона 14. При этом устран етс ток самоиндукции. Соответственно с электромагнитного клапана 5 питание снимаетс через искрогас щий диод 11, резистор 12 и стабилитрон 15.and causes contact 2 or 3 to open. Power is removed from the solenoid valve 4 through a series circuit made up of a spark-suppressing diode 10, a resistor 12 and a zener diode 14. This eliminates the self-induction current. Respectively from the electromagnetic valve 5, the power is removed through the spark-suppressing diode 11, the resistor 12 and the zener diode 15.
В первый момент времени после разрыва управл ющей цепи под действием ЭДС самоиндукции пробиваетс один из стабилитронов 14 или 15, ток в контуре начинает убывать по экспоненте с посто нной времени , определ емой динамическими сопротивлени ми стабилитрона и диода и активными сопротивлени ми регулируемого резистора и обмотки электромагнитного клапана . Напр жение на контуре в этот момент равно сумме падений напр жений на диоде , регулируемом резисторе и стабилитроне . При токе, меньшем минимального тока стабилизации, сопротивление разр дной цепи увеличиваетс и далее процесс уменьшени тока в контуре протекает со значительно меньшей посто нной времени. Так как врем работы стабилитрона значительно меньше общего времени переходного процесса, то мощность, рассеиваема на стабилитроне, настолько мала, что позвол ет обойтись маломощным диодом и стабилитроном .At the first moment of time after the control circuit breaks, under the action of self-induction EMF, one of the Zener diodes 14 or 15 is punched, the current in the circuit begins to decrease exponentially with a constant time determined by the dynamic resistance of the Zener diode and the active resistance of the adjustable resistor and electromagnetic winding valve. The voltage on the circuit at this moment is equal to the sum of the voltage drops on the diode, the adjustable resistor and the zener diode. With a current less than the minimum stabilization current, the resistance of the discharge circuit increases and then the process of reducing the current in the circuit proceeds with a much shorter time constant. Since the operating time of the Zener diode is significantly less than the total transient time, the power dissipated at the Zener diode is so small that it allows you to get by with a low-power diode and a Zener diode.
Использование предлагаемого устройства по сравнению с известным обеспечит повышение схемной и эксплуатационной надежности устройства за счет снижени перенапр жени на коммутирующих электромагнитные клапаны элементах и повышени коэффициента запаса (по мошности) примен емых элементов и улучшение энергоэкономических и весогабаритных характеристик за счет обеспечени возможности бесконтактной коммутации электромагнитных клапанов и применени маломощных элементов.The use of the proposed device in comparison with the known one will provide an increase in the circuit and operational reliability of the device by reducing the overvoltage of the switching electromagnetic valves and increasing the safety factor (in terms of power) of the elements used and improving the energy-saving and weight-dimensional characteristics by providing non-contact switching of the electromagnetic valves and use of low-power elements.
