Description

Дл  измерени  сеточных токов электронных ламп пользуютс  обычио методом компенсации напр жени , создаваемого сеточным током ни высокоомном сопротивлении, или различными методами измерени  зар да , создаваемого сеточным током на обкладках включенного в цепь сетки конденсатора.To measure the grid currents of the electron tubes, one uses the usual method of compensating for the voltage generated by the grid current or high resistance, or various methods of measuring the charge created by the grid current on the plates of the capacitor grid connected to the circuit.

Известные компенсационные схемы применимы дл  измерени  токов до а и мало пригодны дл  токов пор дка а и меньше.The known compensation circuits are applicable for measuring currents up to a and are not suitable for currents of the order of a and less.

Согласно предлагаемому способу, дл  измерени  сеточного тока электронной лампы пор дка а, измер емый ток следует компенсировать при помощи включенного в сеточную цепь фотоэлемента, освещаемого электрической лампой накаливани , и отсчитывать компенсируемый ток по показани м измерител  тока малой чувствительности, наход щегос  в цепи указанной лампы накаливани .According to the proposed method, to measure the grid current of the electron tube of the order a, the measured current should be compensated with a photocell included in the grid circuit, illuminated by an electric incandescent lamp, and the compensated current should be counted according to the indications of a low-sensitivity current meter filament.

Принципиальна  схема устройства дл  осуществлени  предлагаемого способа представлена на чертеже.A schematic diagram of an apparatus for carrying out the proposed method is shown in the drawing.

О величине тока в цепи фотоэлемента Ф суд т по показани м миллиамперметра Л, контролирующего величину тока в цепи лампы накаливани  Л-2, освещающей фотоэлемент Ф. .О величине напр жени  на сетке исследуемой лампы суд т по показаии м прибора А-2 в анодиой цепи лампы JJ.(ionic) grid current, is compensated by the current of the vacuum photocell F included in the grid circuit. The magnitude of the current in the photocell circuit F is judged by the readings of a milliammeter L, which controls the magnitude of the current in the L-2 lamp circuit, illuminating the photocell F. The magnitude of the voltage on the grid of the test lamp is judged by the indications of device A-2 in the anode JJ lamp chains.

Таким образом, пол чаетс  удобна  схема дл  сн ти  зависимостиThus, a convenient scheme is obtained for removing the dependencies
