Description
Предлагаемое изобретение касаетс устройства дл питани цепи накала катодных ламп переменным током с применением трансформатора, вторична обмотка которого разделена на две части. Согласно изобретению, с целью точного нахождени средней точки вторичной об-, мотки, между част ми последней включено сопротивление с движком, соединенным со средним проводом устройства.The present invention relates to an apparatus for supplying the cathode lamp filament circuit with alternating current using a transformer, the secondary winding of which is divided into two parts. According to the invention, in order to accurately find the middle point of the secondary obel, between the parts of the latter, a resistance is connected with a slider connected to the middle conductor of the device.
Устройство, схема которого изображена на чертеже, состоит из трансформатора, первична обмотка А которого питаетс от сети /, 2 переменн|&го тока, а вторична обмотка ВС, питающа цепь накала лампы, разделена на две части В и С, соединенные между собою при помощи регулируемого сопротивлени . Дл более точного отыскани средней точки вто ричной обмотки трансформатора это регулируемое сопротивление разделено на две части, соединенные между собою проволокой 7-8, например из никвгел , на которой установлен движок, соединенный со средним проводом устройства.The device, whose circuit is shown in the drawing, consists of a transformer, the primary winding A of which is powered from the mains /, 2 alternating current, and the secondary winding, feeding the lamp filament circuit, is divided into two parts B and C, interconnected with adjustable resistance. In order to more accurately find the midpoint of the secondary winding of the transformer, this adjustable resistance is divided into two parts, connected together with a 7-8 wire, for example, from nickel, on which a slider is mounted, connected to the middle wire of the device.
Нить накала катодных ламп приключаетс к зажимам 5 и 5 вторичной обмотки трансформатора, а средний провод 4 движка-к аноду. Между зажимами 5, 4,3 включаютс конденсаторы 6,The filament of the cathode lamps comes to the terminals 5 and 5 of the secondary winding of the transformer, and the middle wire 4 of the slider to the anode. Between clamps 5, 4.3, capacitors 6 are turned on,
