Description

совани  5 и корректирующее звено 6 соединен с сумглатором 7, Датчик напр жени  8 через дифференцирующее зве но 9 также соединен с сумматором 7, выход которого, в свою очередь, подключен ко входу тиристорного преобразовател . . Устройство работает следуквдим образом. При отклонении тока дуги от заданнего значени  сигнал рассогласовани  на выходе блока 5 поступает на корректи1 )ук1цее звено 6, выходной сигнал которого после сложени  на сумматоре 7 с сигналом, пропорциональным скорости изменени  напр жени  дуги , с выхода диффёренцирук цего звена 9 поступает на управл ющий вход тиристорного преобразовател  1 и измен ет его выходное напр жение таким образом , чтобы уменьшить сигнгш рассогласовани  до нул . Использование новых элементов диф ференцирующего звена и сумматора поз вол ет уменьшить габариты и стоимост всего устройства путем уменьшени  сглаживающего реактора при одновреме ном повышении устойчивости и качеств стабилизации тока плазмотрона. Форцула- изобретени  Устройство дл  регулировани  режима плазмотрона посто нного тока, содержащее тиристорный преобразователь, выход которого соединен со сглаживающим реактором, подключенным к плазьютрону , датчик напр жени  и датчик тока , соединенный своим выходом со входом формировател  сигнала рассогласовани , выход которого через корректирующее звено соединен с тиристорным преобразователем, отличающеес  темг что, с целью улучшени  качества регулировани  путем повышени  точности стабилизации тока, оно снабжено сумматором, включенным между корректирующим звеном и тиристорным преобразователем, и дифференцирующим звеном, выход которого подключен ко второму входу сумматора, а вход - к датчику напр жени . .

Электротехника , № 12, 1968.5 and corrective link 6 are connected to the sumgator 7, the voltage sensor 8 through the differentiating link 9 is also connected to the adder 7, the output of which, in turn, is connected to the input of the thyristor converter. . The device works in the following way. When the arc current deviates from the predetermined value, the error signal at the output of block 5 is fed to corrections1) link 6, the output signal of which, after adding on the adder 7 to a signal proportional to the rate of change of arc voltage, goes from the output of differential link 9 to the control input thyristor converter 1 and changes its output voltage in such a way as to reduce the signal error to zero. The use of new elements of the differentiating link and adder makes it possible to reduce the size and cost of the entire device by reducing the smoothing reactor while simultaneously increasing the stability and stabilization properties of the plasma torch current. Formula Invention A device for controlling a DC plasmatron mode, comprising a thyristor converter, the output of which is connected to a smoothing reactor connected to a plasma cell, a voltage sensor and a current sensor connected to the output of the error generator, which is output through an adjusting link to a thyristor converter, characterized in that, in order to improve the quality of regulation by increasing the accuracy of current stabilization, it is equipped with an adder, in for prison between the correcting element and a thyristor converter, and a differentiating element, the output of which is connected to the second input of the adder, and an input - to the sensor voltage. .
