Description

Предлагаемое изобретение состоит особой срорме выполнени  катодного усилител , сетка усилительной лампы которого снабжена двум  выводами. Нить накала этой ламы питаетс  переменным , а цепь анода постб нным током.The present invention consists of a special design of the cathode amplifier, the grid of the amplifying lamp of which is equipped with two terminals. The filament of this llama is powered by variables, and the anode circuit is supplied with a post-current.

На чертеже изображена схема усилител .,The drawing shows an amplifier circuit.,

Сетка лампы усилител  присоединена к концам обмотк и 7 трехобмоточного трансформатора Тр2, втора  обмотка которого включена в цепь накала, а первична  обмотка (треть ) присоединена к источнику переменного тока. В цепь анода, питаемую от анодной батареи, включена первична  обмотка выходного трансформатора ТрЗ, Возбуждение лампы от вторичной обмотки трансформатора Тр1 подводитс  к средним точкам двух упом нутых выше вторичных обмоток / и 2 трансформатора Тр2.The grid of the amplifier lamp is connected to the ends of the winding and 7 of the three-winding transformer Tr2, the second winding of which is included in the heating circuit, and the primary winding (one third) is connected to the alternating current source. The anode circuit fed from the anode battery includes the primary winding of the output transformer TZ. The excitation of the lamp from the secondary winding of the transformer Tr1 leads to the midpoints of the two above mentioned secondary windings / and 2 transformers Tr2.

Сетка лампы выполнена из материала, обладающего достаточным сопротивлением , вследствие чего пад,ение напр жени  вдоль этой сетки можно подобрать таким образом, чтобы разности потенциалов всех ее точек по отношениюThe lamp grid is made of a material with sufficient resistance, as a result of which the voltage drop along this grid can be selected so that the potential differences of all its points with respect to

к противолежащим точкам нити накала были равны между собою независимо от колебаний переменного тока катода. Благодар  этому все части сетки при подведении возбуждени  будут находитьс  в одинаковых услови х и-лампа будет работать достаточно четко.to the opposite points, the filaments were equal to each other regardless of the oscillations of the alternating current of the cathode. Due to this, all parts of the grid will be under the same conditions when driving the excitation and the lamp will work quite clearly.

Описанна  система питани  сетки дл  выравнивани  разности потенциалов между двум  электродами может быть, в случае наличи  нескольких сеток, применена по отношению к любой из них или ко всем вместе.The described grid feeding system for equalizing the potential difference between the two electrodes can be, in the case of several grids, applied to either of them or to all of them.

Предмет изобретени .The subject matter of the invention.

Катодньш усилитель с применением усилительной лампы, сетка которой снабжена двум  выводами, при чем цепь накала питаетс  переменным током, а цепь анода - посто нным, отличающийс  тем, что сетка включена в обмотку 7 трехобмоточного трансформатора 7р2, в обмотку 2 когорого включена цепь накала; а в третью обмотку которого включен источник переменного тока , питающего цепь накала.A cathode amplifier with the use of an amplifying lamp, the grid of which is equipped with two terminals, with the filament circuit powered by alternating current and the anode circuit constant, characterized in that the grid is included in the winding 7 of the three-winding transformer 7p2, the coil of the incandescence circuit 2 is connected; and in the third winding of which the source of alternating current feeding the glow circuit is included.
