Description

напр жени . Сигнал, пропорциональный действующему значению тока, с выхода блока 3 задани  мощности подаетс  на один из входов блока сравнени . О1гаал, пропорциональный действующему значению напр жени , снимаемый с блока 6 вычислени  действующего значени  напр жени  подаетс  на другой вход блока 7, сравнени .tension A signal proportional to the actual value of the current from the output of the power setting unit 3 is applied to one of the inputs of the comparison unit. A gal, proportional to the actual voltage value, taken from the current voltage value calculation block 6 is fed to another input of the block 7, the comparison.

В блоке 7 сравнени  сигналы действующих значений тока и напр жени  сравниваютс , и сигнал рассогласовани  подаетс  в усилитель 8, где усиливаетс  и определенной пол рности передаетс  исполнительному механизму 9, который перемещает электрод 2 в сторону устранени  возмущени .In comparison unit 7, the signals of the effective values of current and voltage are compared, and the error signal is fed to the amplifier 8, where it is amplified and of a certain polarity is transmitted to the actuator 9, which moves the electrode 2 towards the elimination of disturbance.

Использование новых элементов - блоков вычислени  действующих значений тока и напр жени  уменьшает погрешность, обусловленную детектированием сигналов и изменением коэффициента их формы, вследствие значительной несинусоидальности величин тока и напр жени  во врем  работы печи. В результате повьшиетс  точность- поддержани  режима, активна  вводима  мощность и улучшаетс  техника - экономические показатели работы печи.The use of new elements — units for calculating the effective values of current and voltage — reduces the error due to the detection of signals and the change in their shape factor, due to the considerable non-sinusoidality of the current values and voltage during operation of the furnace. As a result, the accuracy of maintaining the mode increases, the input power is active and the equipment is improved - the economic performance of the furnace.
