Summary of the invention
The object of this invention is to provide a kind of 132kV level 36 pulse wave drive rectifier transformer, single transformer is two splitted construction, and 12 pulse waves export, and 3 transformers connected in parallel with different phase shift angle realize 36 pulse waves outputs, improve the quality of power supply, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is:
A kind of 132kV level 36 pulse wave drive rectifier transformer, comprises iron core, low pressure basic winding I, low pressure Phase shift winding I, earth shield, high pressure winding I, high pressure winding II, the basic winding II of low pressure and low pressure Phase shift winding II; Rated primary voltage is that 132kV, D connect, all insulation structure; The two division of secondary side, phase shift, phase shift angle mutual deviation 10 °, single transformer exports 12 pulse waves, and three transformers export 36 pulse waves; Every platform transformer comprises three phase three limb core and winding, and every phase winding is formed by the low pressure winding be sleeved on successively from inside to outside on iron core, high pressure winding; The basic winding II of low pressure of the low pressure basic winding I that described low pressure winding comprises axially-aligned and low pressure Phase shift winding I, axially-aligned and low pressure Phase shift winding II, the basic winding of low pressure and Phase shift winding axially-aligned; It is that upper and lower two-way is in parallel that described high pressure winding comprises high pressure winding I and high pressure winding II, high pressure winding I and high pressure winding II; Between described high pressure winding, low pressure winding, earth shield is set; Adopt secondary side phase shift, secondary side does not have tap, and phase shifting angle precision is high, secondary side phase shift angle mutual deviation 10 °, and single transformer exports 12 pulse waves, and three transformers export 36 pulse waves.
Described low pressure Winding tap bit copper band, axial lead, lifts one's head and dresses outside aluminium foil crimped paper, uniform electric field, prevent partial discharge.
The two division of 132kV of the present invention, phase shift drive rectifier transformer, rated primary voltage 132kVD connects, the two division of secondary side, phase shift.Compare and the phase shift of background technology primary side, adopt secondary side phase shift, because secondary side does not have tap, phase shifting angle precision is high.Secondary side phase shift angle mutual deviation 10 °, single transformer exports 12 pulse waves, and three transformers export 36 pulse waves.The basic winding of low pressure and low pressure Phase shift winding axially-aligned, more radial arrangement architecture, not only reduced volume of transformer, reduced transformer loss, and improve the mechanical strength of low pressure winding, bore short-circuit capacity strong; Between high and low pressure winding, earth shield is set, reduces net side overvoltage to the impact of valve side rectifier cell and valve side harmonic component to the impact of electrical network; Low pressure Winding tap dresses outside aluminium foil crimped paper, can uniform electric field, reduces partial discharge.Compare with common rectifier transformer, the present invention can not only save material and machining period consumption, and can reduce transformer loss, improves transformer and bears short-circuit capacity.
Good effect of the present invention: the basic winding of low pressure and Phase shift winding axially-aligned, width was to arrangement architecture more in the past, improved spatial transformer utilance, reduced volume of transformer, reduce production cost; High pressure winding is that 132kV, D connect, all insulation structure; Between high and low pressure winding, earth shield is set, reduces net side overvoltage to the impact of valve side rectifier cell and valve side harmonic component to the impact of electrical network; Compare with common rectifier transformer, the present invention is insulated reliably, bear that short-circuit capacity is strong, phase shifting angle precision is high; Single transformer is two splitted construction, and 12 pulse waves export, and 3 transformers connected in parallel with different phase shift angle realize 36 pulse waves outputs, improve the quality of power supply.
