Description
Предметом изобретени вл етс лалпювый генератор с самовозбуждением дл индукционного нагрева и плавки металлов. В нем между нагревательным контуром и лампоГ| включен промежуто1 ный контур, индуктивно св занный с нагревательным контуром. В ламиовых генераторах подобного типа наблюдаетс в,1ение зат гивани , которое состоит 3 том, что в процессе нагревани и плавки шихты ироисходит резкое л 1ежелательиое изменение частоть и iie/iUiMa работы генератора. Поэтому в иромышленных установках такие xcTpoiicTBa не нашли применени .The subject of the invention is a self-excited Lappy generator for induction heating and melting of metals. It between the heating circuit and the lamp | an intermediate loop is connected inductively connected to the heating loop. In lamic oscillators of this type, it is observed in 1 of the indentation, which consists in the fact that in the process of heating and melting the charge, there is a sharp change in the frequency and iie / iUiMa of the generator. Therefore, in industrial installations such xcTpoiicTBa have not been applied.
В нредлагаемом ламповом геиераторе вление зат гивани устранено путем иодачи наир жени обратной св зи в цеиь сетки ламны с нагревательного контура.In the proposed lamp geieratora, the tightening phenomenon is eliminated by iodizing our feedback to the chains of the lamp from the heating circuit.
На чертеже изображена схема предлагаемого ламнового генератора.The drawing shows a diagram of the proposed lamnogo generator.
В цеиь анода ламнового генератора включен контур LiCi, который индуктивно св зан (/Vl-взаимна индуктивность) с нагревательным контуром LC2LL. На чертеже обозначены: Р-рубильник дл иодключени емкости. Я/-расплавл ема шихта. В этой двухкоитурной схеме напр жение обратной св зи вз то с катхшки L нагревате,1ьного контура. При таком сиособе подачи обратиой св зи зат гивание устран етс благодар тому, что обратна св зь оказываетс недостаточной дл генерации более высокой частоты, так как дл этой частоты нагревательHbiii контур представл ет собой малое сопротивление.A LiCi circuit is connected to the anode of the lam-oscillator, which is inductively coupled (/ Vl-mutual inductance) with the LC2LL heating circuit. In the drawing are marked: P-switch for capacitance connection. I / smelt blend. In this two-colouri circuit, the feedback voltage is taken from the K Lathka L Heater, 1 loop circuit. With this reversal connection supply method, the puffing is eliminated due to the fact that the feedback is not sufficient to generate a higher frequency, since for this frequency the Hbiii heater circuit is low resistance.
