Embodiment Construction
[0011] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.
[0012] A 132kV class 36-pulse drive rectifier transformer, including iron core 1, low-voltage basic winding I2, low-voltage phase-shifting winding I3, ground shield 4, high-voltage winding I5, high-voltage winding II6, low-voltage basic winding II7 and low-voltage phase-shifting winding II8; The rated voltage of the side is 132kV, D connection, fully insulated structure; the secondary side is double-split, phase-shifted, and the phase-shift angles are 10° different from each other. A single transformer outputs 12 pulses, and three transformers output 36 pulses; each transformer includes Three-phase three-column iron core and winding, each phase winding is composed of a low-voltage winding and a high-voltage winding that are sequentially placed on the iron core from inside to outside; the low-voltage winding includes low-voltage basic winding I2 a...
