Description
Изобретение относитс к электрической схеме сварочной машины посто нного тока с независимым возбуждением .This invention relates to a circuit diagram of a DC welding machine with independent excitation.
С целью получени резко падающей внешней характеристики предлагаетс специально подобранное сопротивление в цепи возбуждени одновременно включать последовательно в цепь дуги.In order to obtain a sharply falling external characteristic, a specially selected resistance in the excitation circuit is proposed to be simultaneously connected in series with the arc circuit.
На чертеже изображена электрическа схема .предлагаемой машины.The drawing shows an electrical diagram of the proposed machine.
В этой схеме посторонний источник посто нного тока П, обмотка независимого возбуждени в и сопротивление /, включенное последовательно в цепь сварочного тока, образуют замкнутую цепь.In this circuit, an extraneous direct current source P, an independent excitation winding in and a resistance / connected in series to the welding current circuit, form a closed circuit.
При работе машины растет падение напр жени в сопротивлении К. Благодар росту этого падени напр жени сила тока возбуждени уменьшаетс When the machine runs, the voltage drop in resistance K increases. Due to the increase in this voltage drop, the field current is reduced
(М:(M:

..
вследствие чего уменьшаетс напр жение : кор I.,as a result, the voltage decreases: core I.,
Таким образом, характеристика сварочной машины получаетс падающей.Thus, the characteristic of the welding machine is obtained falling.
Сопротивление R может быть выполнено как одно целое с успокоительным дросселе или отдельно.Resistance R can be made as one unit with a soothing choke or separately.
Противономпаундна обмотка а может также отсутствовать.Counter-wound winding may also be absent.
Предмет изобретени .The subject matter of the invention.
