|Product Name||wholesale china factory 220KV 330KV 550KV power transformer|
|load capacity of the transformer||The transformer load capacity and accident overloading capacity meet the requirement of GB/T15164 oil-immersed power transformer load guide|
|Transformer structural requirements||Transformer oil: insulation oil of transformer is 25# transformer oil.|
The iron core is made of high quality magnetic cold-rolled oriented silicon steel sheet with full oblique joints at 45 degrees. The surface of the iron core is sealed with special resin, resistant to moisture and stainless steel. The core lamination adopts the latest step lamination method to reduce the no-load loss and no-load current.
The high and low voltage winding of the transformer is made of high quality material, which makes the winding ampere-turns balanced, has strong resistance to short circuit, and reduces the eddy current loss of the winding.
|Operation principle||High pressure of 35 KV, D connection, low voltage is 4 x 1.0 KV, using two groups of yanbian delta connection, in addition, respectively is the delta connection and Y connection to phase shifting transformer rectifier, yanbian triangle phase-shifting Angle of plus or minus 15 degrees, a 24-pulse rectifier transformer combination, if delta connection and low voltage transformer used Y connection to use, can be composed of 12 pulse wave, two groups of yanbian delta connection can also be used 12 pulse, low pressure 4 set of coils can be used at the same time run 24 pulse wave respectively.|
