Abstract
Способ параметрической стабилизации процесса контактной сварки, предусматривающий перед началом сварки определение напряжения питающей сети Uc, коэффициента трансформации на данной ступени Km и индуктивного сопротивления X2k в режиме короткого замыкания, а в процессе сварки измерение в каждом периоде коэффициента мощности cosφ и принятие решения о корректировке угла αj+1 включения тиристоров в следующем периоде, отличающийся тем, что значение αj+1 на интервале Uн±ΔU, где Uн и ΔU - номинальное напряжение сети и его допускаемое отклонение, по формуле ! αj+1=A1·(Uc-Uн)+A0, ! где A0 и A1 - коэффициенты, зависящие от cosφ, которые определяют как коэффициенты линейного двучлена наилучшего равномерного приближения в соответствии с формулами ! и , ! где α' и α'' задают для значений и как результат решения относительно α уравнения ! , ! где I2 - заданное значение сварочного тока; ! ki - коэффициент регулирования сварочного тока, который зависит от значений α и cosφ. The method of parametric stabilization of the resistance welding process, which involves determining the supply voltage Uc, the transformation coefficient at this stage Km and the inductive resistance X2k in the short circuit mode before starting welding, and during the welding process, measure the power factor cosφ in each period and decide on the correction of the angle αj +1 turn on of the thyristors in the next period, characterized in that the value αj + 1 in the interval Un ± ΔU, where Un and ΔU are the rated voltage of the network and its permissible deviation, according to Ole! αj + 1 = A1 · (Uc-Un) + A0,! where A0 and A1 are cosφ-dependent coefficients, which are defined as the linear binomial coefficients of the best uniform approximation in accordance with the formulas! and,! where α 'and α' 'are given for the values and as a result of the solution of the equation with respect to α! ! where I2 is the set value of the welding current; ! ki is the welding current control coefficient, which depends on the values of α and cosφ.
