Description
жаетс батаре конденсаторов через сварочный трансформатор 20.A capacitor battery is fed through the welding transformer 20.
Напр жение f/g на сварочных электродах возрастает. В момент, когда t/g, подаваемое на схему 10 сравнени , превысит опорное напр жение от источника 11, на выходе схемы 10 сравнени возникает напр жение рассогласовани , которое подаетс на сумматор 12 и далее на управл емый шунт 16.The f / g voltage on the welding electrodes increases. At the moment when t / g supplied to the comparison circuit 10 exceeds the reference voltage from source 11, the output voltage of the comparison circuit 10 causes a misalignment voltage that is applied to the adder 12 and then to the controlled shunt 16.
Это соответствует времени ti на осциллограммах (О и (t).This corresponds to the time ti on the oscillograms (O and (t).
Далее происходит поддержание посто нного напр жени на электродах до момента достижени в зоне сварки заданной температуры tzК моменту 4 температура в зоне сварки достигает заданного значени , и на выходе схемы 8 сравнени возникает напр жение рассогласовани , подаваемое на сумматор 12 и одновременно запускающее электронное реле 13 времени.Next, a constant voltage is maintained at the electrodes until a predetermined temperature tz is reached in the welding zone. At time 4, the temperature in the welding zone reaches a predetermined value, and the output voltage of the comparison circuit 8 causes an error voltage that is applied to the adder 12 and simultaneously starts the electronic time relay 13 .
В дальнейшем происходит поддержание заданной температуры в зопе сварки. При этом ток сварки уменьшаетс , что приводит к уменьшению напр жени на сварочных электродах .In the future, the preset temperature is maintained at the welding zope. In this case, the welding current decreases, which leads to a decrease in voltage at the welding electrodes.
Через отрезок времени 4-ta, на которое настроено реле времени, выдаетс импульс на управл юш.ий электрод тиристора 19, тиристор открываетс и шунтирует сварочный трансформатор 20. Процесс сварки прекращаетс .After a time interval of 4-ta, to which the time relay is tuned, a pulse is given to the control electrode of the thyristor 19, the thyristor opens and shunts the welding transformer 20. The welding process stops.
