Description

ПреДоТагаетс  устройство дл  регз ировани  скорости двигател  посто нного тока, питаемого от управл емых ионных вентилей. В нем, как и в известных устройствах подобного рода, применены фазорегул тор дл  подачи управл ющего напр жени  на сетки вентилей, датчик скорости двигател  и усилитель, установленный между датчиком и регулирующим элементом фазорегул тора.A device is provided to regulate the speed of a DC motor powered by controlled ionic valves. In it, as in the known devices of this kind, a phase regulator is used to supply control voltage to the grid of valves, an engine speed sensor and an amplifier mounted between the sensor and the regulator element of the phase regulator.

Описываемое устройство  вл етс  более соверщенным, так как обеспечивает устойчивую работу при высокой точности регулировани  в щироком диапазоне скоростей. Эти преимущества достигаютс  включением между датчиком и усилителем инерционного звена, составленного из сопротивлени , емкости и усилительной лампы.The described device is more perfect as it ensures stable operation with high precision of regulation in a wide range of speeds. These advantages are achieved by switching between the sensor and the inertial link amplifier made up of resistance, capacitance, and an amplifying lamp.

На чертеже приведена электрическа  схема устройства.The drawing shows the electrical circuit of the device.

Источником питани   корной цепи регулируемого двигател  Д служит управл емый ионный преобразователь , состо щий из силового трансформатора TI и двух тиратронов ТГ, соединенных по схеме двухполупериодного выпр млени .The power source of the dormant motor circuit of the motor D is a controlled ion transducer consisting of a power transformer TI and two TG thyratrons connected in a full-wave rectifier circuit.

Обмотка возбуждени  двигател  питаетс  независимо от цепи  кор .The motor excitation winding is powered independently of the core circuit.

Устройство дл  регулировани  скорости воздействует на сеточные цепи тиратронов ТГ. Напр жение на сетки тиратронов подаетс  от трансформатора TZ, питающегос  от фазорегул тора , в одно из плеч которого включена лампа Лз, а в другое - конденсатор С. Фазорегул тор питаетс  от трансформатора Т.A device for speed control acts on the grid chains of TG thyratrons. The voltage on the grids of the thyratrons is supplied from a transformer TZ, powered by a phase regulator, in one of whose arms the lamp Lz is switched on, and in the other - by a capacitor C. The phase regulator is powered by a transformer T.

На валу регулируемого двигател  Д установлен датчик скорости двигател , выполненный в виде тахогенератора Т.An engine speed sensor is installed on the shaft of the regulated engine D, made in the form of a tachogenerator T.

Разность напр жений тахогенератора Г и установочного потенциометра П подаетс  последовательно с падением напр жени  на сопротивлении У на сетки ламп JJi и Лг усилител  и после усилени  на сетку лампы Лз фазорегул тора.The voltage difference between the tachogenerator G and the setpoint potentiometer P is applied in series with the voltage drop across the resistance U on the grids of the lamps JJi and Lg of the amplifier and after amplification of the phase regulator to the grid of the lamp Lz.

В схему введено инерционное звено , состо щее из сопротивлени  R с, конденсатора С .м усилительной лампы Лг и обеспечивающее устойчивую работу схемы при точности поддержани  скорости до 0,1-0,2% и диапазоне регулировани  500:1 при скорости протекани  переходных процессов пор дка 0,2-0,3 секунды.An inertial link is introduced into the circuit, consisting of the resistance R c, the capacitor C of the amplifying lamp Lg, which ensures stable operation of the circuit with an accuracy of maintaining the speed up to 0.1-0.2% and an adjustment range of 500: 1 at the rate of transient pores For 0.2-0.3 seconds.
