Description

Известные трансформаторы дл  дуговой ;Сварки, имеющие многостержневой магнитопровод, три первичных обмотки, включаемых в трехфазную сеть, и одну вторичную однофазную обмотку, не обеспечивают получени  требуемых сварочных характеристик.Known transformers for arc welding; having a multi-core magnetic conductor, three primary windings connected to a three-phase network, and one secondary single-phase winding do not provide the required welding characteristics.

С целью получени  вторичного напр жени  тройной частоты и улучшени  характеристик трансформатора предлагаетс  магнитопровод выполн ть в виде трех независимых двухстержневых сердечников с увеличенной магнитной индукцией, а вторичную обмотку выполн ть в виде одной катушки, охватывающей три стержн  магнитопровода.In order to obtain a triple frequency secondary voltage and improve the transformer characteristics, it is proposed that the magnetic core be made in the form of three independent double-core cores with increased magnetic induction, and the secondary winding should be made in the form of a single coil spanning three magnetic cores.

Схема трансформатора, по сн юша  его устройство, представлена на чертеже.A diagram of a transformer, according to its device, is shown in the drawing.

На трех независимых двухстержневых сердечниках / расположены три однофазных первичных обмотки 2, соединенных в звезду и.включаемых в трехфазную сеть. Вторична  обмотка 5 охватывает три сердечника магнитопровода. Первичные обмотки и магнитопровод трансформатора рассчитываютс  так, чтобы магнитна  индукци  в сердечниках имела повышенное значение пор дка 18000-22000 гаус. В этом случае в магнитном потоке возникает, кроме основной волны, треть  гармоническа  составл юща . Соответственно этому во вторичной обмотке возникнет электродвижуща  сила тройной частоты. Сумма э.д.с. основной волны в первичных обмотках равна нулю, так как при трехфазном питании магнитные потоки основной волны в отдельных сердечниках магнитопровода расположены под углом 180° и сумма их равна нулю.On three independent double core cores / there are three single-phase primary windings 2, connected in a star and connected to a three-phase network. The secondary winding 5 covers the three cores of the magnetic circuit. The primary windings and the magnetic core of the transformer are calculated so that the magnetic induction in the cores has an increased value in the order of 18000-22000 gaus. In this case, in addition to the main wave, a third harmonic component arises in the magnetic flux. Accordingly, a triple frequency electromotive force arises in the secondary winding. Amount of emf The main wave in the primary windings is zero, since with a three-phase power supply, the magnetic fluxes of the main wave in individual cores of the magnetic core are located at an angle of 180 ° and their sum is zero.

При указанных значени х индукции величина третьей гармонической составл ющей потока достаточна дл  получени  во вторичной обмотке трансформатора напр жени  60-65 в, необходимого дл  сварки.With the indicated induction values, the third harmonic component of the flow is sufficient to produce a voltage of 60-65 V in the secondary winding of the transformer, which is necessary for welding.

Наличие у предлагаемого трансформатора трехфазной первичной обмотки дает возможность равномерно загружать трехфазную сеть, аThe presence of the proposed transformer three-phase primary winding makes it possible to uniformly load the three-phase network, and
