Description

Изобретение касаетс  бесконтактных устройств дл  управлени  электрическими аппаратами с переменной индуктивностью (например, контакторами и реле переменного тока).The invention relates to contactless devices for controlling electrical devices with variable inductance (e.g., contactors and AC relays).

Известны феррорезонансные магнитные бесконтактные выключатели дл  нагрузок с переменной индуктивностью, состо щие из феррорезонансного магнитного усилител , в цепь нагрузки которого включена переменна  индуктивность. Предлагаемое изобретение имеет цель уменьшить потребл емую усилителем мощность и снизить его габариты.Ferroresonant magnetic proximity switches for loads with variable inductance are known, consisting of a ferroresonant magnetic amplifier whose variable inductance is included in the load circuit. The present invention aims to reduce the power consumed by the amplifier and reduce its dimensions.

Отличительной особенностью изобретени   вл етс  то, что переменна  индуктивна  нагрузка щунтируетс  емкостью, создающей дополнительный резонансный контур.A distinctive feature of the invention is that a variable inductive load is shunted by a capacitor creating an additional resonant circuit.

На чертеже приведена принципиальна  электрическа  схема бесконтактного управлени  контактором.The drawing shows a circuit diagram of a contactless control contactor.

Последовательно с нагрузочными обмотками W магнитного усилител  МУ и емкостью Ci к питающей сети присоединена обмотка контактора К, защунтированна  емкостью С.Consistently with the load windings W of the magnetic amplifier MU and the capacitance Ci, the coil of contactor K is connected to the mains supply and is clamped by the capacitor C.

При отсутствии сигнала в обмотке управлени  IF магнитного усилител  МУ, сопротивление его нагрузочных обмоток W наиблоьщее и и по цепи нагрузочных обмоток и обмотке контактора течет ток, недостаточный дл  вт гивани  контактора /С.In the absence of a signal in the control winding IF of the magnetic amplifier MU, the resistance of its load windings W is most pronounced and there is not enough current through the circuit of the load windings and the winding of the contactor to retract the contactor / C.

При присоединении обмотки управлени  Wy к источнику посто нного тока магнитный усилитель МУ подмагничиваетс  и сопротивление его нагрузочных обмоток IF уменьшаетс . Через обмотку контакгора /С протекает ток, достаточный дл  срабатывани  контактора. При включении контактора К, реактивное сопротивление его обмотки возрастает , и если бы не было емкости Сь могло быть уменьшение тока в цепи обмотки контактора. Емкость С, выбираетс  таким образом, чтобыWhen the control winding Wy is connected to the direct current source, the magnetic amplifier MU is magnetised and the resistance of its load windings IF decreases. A sufficient current is flowing through the contactor / C winding to operate the contactor. When the contactor K is switched on, the reactance of its winding increases, and if there were no capacitance C, there could be a decrease in the current in the contactor winding circuit. Capacity C is selected so that
